TECHNICAL FIELD
[0001] The present invention relates to a destination floor registration device for registering a destination floor of a user in a destination oriented allocation system (DOAS, elevator destination prediction system).
BACKGROUND ART
[0002] In elevator systems, there is provided a destination oriented allocation system (DOAS, elevator destination prediction system) that has a destination floor registration device installed in an elevator hall, and optimally operates a plurality of elevators on the basis of destination floors registered from the destination floor registration device. [0003] In DOAS, the destination floor registration device has been used to input a number or an alphabet of the destination floor or to input a floor name of the destination floor, such as a restaurant floor or a parking lot. Thus, as a specific configuration for registering the destination floor, the destination floor registration device is required to include numeric keys for enabling a user of the elevator to input all the floors, or buttons or a touch panel display device displaying all the floor names of the building. Further, to know whether registration of the destination floor has been steadily performed, or to verify display of the destination floor, the user needs to find the destination floor registered by the user himself/herself from information on all the displayed floors, and verify whether display indicating the registration is shown.
Displaying a large amount of information including unnecessary information on numeric keys or many floor names and prompting the user to select and input

necessary information from among the displayed information force the user to take many operation steps. In addition, there is a problem in that the size of a housing of the device is required to be large enough to display all the numeric keys and all the floor names.
[0004] In DOAS, to cope with such a problem, Patent Literature 1 conventionally discloses a destination floor registration device that selects and displays a candidate of a destination floor on the basis of a use history associated with personal information of a user, the use history having day and time similar to the current time when the user is using the elevator, and determines the destination floor, for example, as a technology for releasing the burden of the user contributed to a large amount of information to be displayed.

SUMMARY OF INVENTION TECHNICAL PROBLEM
[0006] Since the technology disclosed in Patent Literature 1 selects and displays a candidate of a destination floor on the basis of a use history associated with personal information of a user, the use history having similar date and time at a time of registration of the destination floor, information of the destination floor candidates can be narrowed and presented in accordance with the user. However, the user does not necessarily desire to go to the same destination floor as that indicated by the past use history every time, and the user may desire to go to a destination floor different from the

destination floor based on the past use history, depending on a situation at the time of use, a schedule of the day, or the like.
In the destination floor registration device disclosed in Patent Literature 1, only the use history associated with the personal information of the user is taken into consideration, and information of destination floor candidates in consideration of a situation at a time when the uses the elevator, is not presented, besides the use history to be obtained, and there is still a problem in that the destination floor suitable for the current user is not displayed.
[0007] The present invention has been made to solve the above problem, and an object is to provide a destination floor registration device capable of estimating a destination floor in consideration of an attribute of a user and a situation at the time of use and more appropriately presenting a destination floor candidate, which would be selected by the user.

DESCRIPTION OF EMBODIMENTS
[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First Embodiment
FIG. 1 is a diagram for describing a configuration of an elevator system including a destination floor registration device 1 according to a first embodiment of the present invention. FIG. 1 illustrates an example of an elevator system that employs the above-described DO AS.
As illustrated in FIG. 1, the elevator system of the first embodiment includes the destination floor registration device 1, a group management control device 2, an elevator control device 3, and a destination floor display device 4.
The destination floor registration device 1 is a device to which a user registers a destination floor before the user gets on an elevator car. The destination floor registration device 1 is installed in one or a plurality of elevator halls of a building or the like. In the example illustrated in FIG. 1, one destination floor registration device 1 is installed in the elevator hall of each floor of a four-story building, for example. Alternatively, a plurality of the destination floor registration devices 1 may be installed in one elevator hall.
When the user of the elevator performs a destination floor registration operation on the destination floor registration device 1, the destination floor registration device 1 transmits the registered information, that is, a landing call and a destination call to the group management control device 2. [0012] The group management control device 2 has a function to perform group

management control on a plurality of elevators installed in the same building or the like. This group management control device 2 includes the function of DOAS.
To be specific, when receiving the registration information from the destination floor registration device 1, the group management control device 2 allocates an optimum elevator from among the plurality of elevators on the basis of the received registration information. Then, when having performed the allocation to the registration information, the group management control device 2 transmits the allocation information to the destination floor registration device 1 that has transmitted the registration information, and causes the destination floor registration device 1 to display an allocation result. That is, after registering the destination floor, the user sees the allocation result displayed on the destination floor registration device 1 and recognizes the elevator that the user should get on.
[0013] Further, when having performed the allocation to the registration information, the group management control device 2 transmits, to the elevator control device 3 of the allocated elevator, an operation command based on the registration information registered by the user to the destination floor registration device 1. [0014] The elevator control device 3 is provided for each elevator and controls the operation of the elevator, such as running of the car of the elevator, landing on the landing, opening and closing a door of the car.
The destination floor display device 4 is provided on the landing or the car of each elevator, and displays, to the user, the destination floor of the car of the elevator. [0015] Note that, in the first embodiment, as illustrated in FIG. 1, four destination floor registration devices 1, four elevator control devices 3, and four destination floor display devices 4 are provided. However, the present invention is not limited to the example, and the destination floor registration device 1, the elevator control device 3,

and the destination floor display device 4 may be appropriately installed depending on
an installation status at the landing and the number of elevators.
[0016] The first embodiment relates to the destination floor registration device 1
included in the elevator system described in FIG. 1 and can provide the destination floor
registration device 1 that enables presentation of the destination floor candidate in
consideration of an attribute of the user and a situation at the time of use, and more
appropriately display the destination floor candidate, which would be selected by the
user.
[0017] FIG. 2 is a diagram for describing a configuration of the destination floor
registration device 1 according to the first embodiment of the present invention.
The destination floor registration device 1 includes a personal information receiving unit 101, a personal authentication unit 102, a personal information database (DB) 103, a display unit 104, a display control unit 105, an operation receiving unit 106, a registration information creating unit 107, a registration information transmitting unit 108, an elevator-unit instruction receiving unit 109, and a destination floor estimating unit 110.
[0018] The personal information receiving unit 101 receives information for identifying an individual. Here, for example, it is assumed that the personal information receiving unit 101 is a card reader, and a user causes an IC card to be read by the card reader to input the information for identifying an individual, and the personal information receiving unit 101 acquires the input information for identifying an individual. The personal information receiving unit 101 outputs the received information to the personal authentication unit 102 as personal information.
Further, when the personal information is output from the operation receiving unit 106, the personal information receiving unit 101 recognizes an input of the personal

information and acquires the output personal information, and outputs the personal information to the personal authentication unit 102.
[0019] The personal authentication unit 102 acquires the personal information from the personal information receiving unit 101 and performs processing for authenticating the individual with reference to the personal information DB 103. The personal authentication unit 102 outputs personal authentication result information, which is a result of the processing for authenticating the individual, to the destination floor estimating unit 110.
The personal information DB 103 stores information uniquely determining an individual. Note that, in the first embodiment, as illustrated in FIG. 2, the personal information DB 103 is provided in the destination floor registration device 1. However, the embodiment is not limited thereto, and the personal information DB 103 may be provided outside the destination floor registration device 1. [0020] The destination floor estimating unit 110 estimates the destination floor to be presented to the user from the personal authentication result information acquired from the personal authentication unit 102, and information of a situation at a point of time when the personal information of the user has been input to the operation receiving unit 106 described later or the personal information receiving unit 101, that is, information of a situation at the time of using the elevator.
To be specific, when the destination floor estimating unit 110 determines that the personal authentication has succeeded, that is, the user has been able to be identified on the basis of the personal authentication result information acquired from the personal authentication unit 102, the destination floor estimating unit 110 determines the destination floor candidate to be presented to the user from the personal authentication result information and the information of a situation at a point of time when the personal

information has been input, and outputs information of the determined destination floor candidate to the display control unit 105. Further, when the destination floor estimating unit 110 determines that the personal authentication has failed, that is, the user has not been able to be identified on the basis of the personal authentication result information acquired from the personal authentication unit 102, the destination floor estimating unit 110 determines the destination floor candidate to be presented to the user from the information of a situation at a point of time when the personal information has been input, and outputs information of the determined destination floor candidate to the display control unit 105.
[0021] The information of a situation at a point of time when the personal information has been input, that is, the information of a situation at a point of time when the user has operated the destination floor registration device 1 to input the personal information is information of a situation at the time of using the elevator, for example, information of a reception time or a time zone of the reception time of the personal information acquired from the operation receiving unit 106 or the personal information receiving unit 101, information of date and time or a day at the time of using the elevator acquired from a calendar storage unit (not illustrated), information of an event of specific date and time, air temperature information acquired from an air temperature control unit (not illustrated), or the like. What kind of information is acquired as the information of a situation at a time of using the elevator is determined in accordance with a preset condition for destination floor estimation.
The destination floor estimating unit 110 outputs information of the estimated destination floor candidate to the display control unit 105. [0022] The display control unit 105 controls information to be displayed on the display unit 104. To be specific, the display control unit 105 causes the display unit

104 to display the destination floor candidate on the basis of the information of the destination floor candidate acquired from the destination floor estimating unit 110. Further, when a display switching instruction is output from the operation receiving unit 106, the display control unit 105 switches the display on the display unit 104 and causes the display unit 104 to display numeric keys. Further, when the allocation information indicating an elevator unit is output from the elevator-unit instruction receiving unit 109 as specific information regarding allocation of the elevator, the display control unit 105 causes the display unit 104 to display the allocation information.
The display unit 104 displays the destination floor candidate, the numeric keys, or the allocation information of an elevator unit in accordance with the control of the display control unit 105.
[0023] The operation receiving unit 106 receives various operations performed on the destination floor registration device 1 by the user. When receiving the operation of selecting a destination floor from the user, the operation receiving unit 106 outputs destination floor selection information and information of a floor where the destination floor registration device 1 that has received the operation from the user is installed to the registration information creating unit 107 on the basis of the received operation of selecting a destination floor. Further, when receiving the operation of selecting for switching display from the user, the operation receiving unit 106 outputs the received selection information of the switching display to the display control unit 105. Further, the operation receiving unit 106 outputs a time when the operation has been received from the user and the information of a floor where the destination floor registration device 1 that has received the operation from the user is installed to the destination floor estimating unit 110.
Further, when receiving an input of the personal information such as

information indicating that the user is a non-IC card holder, the operation receiving unit 106 outputs the received personal information to the personal information receiving unit 101.
[0024] The registration information creating unit 107 creates registration information, that is, information of the landing call and the destination call, on the basis of the destination floor selection information acquired from the operation receiving unit 106 and the information of a floor where the destination floor registration device 1 that has received the operation from the user is installed, and transmits the registration information to the group management control device 2 through the registration information transmitting unit 108.
The registration information transmitting unit 108 transmits the registration information created by the registration information creating unit 107 to the group management control device 2.
[0025] The elevator-unit instruction receiving unit 109 receives, from the group management control device 2, the allocation information of the elevator unit to the registration information transmitted by the registration information transmitting unit 108, and outputs the received allocation information to the display control unit 105. [0026] FIG. 3 is diagrams illustrating examples of a hardware configuration of the destination floor registration device 1 according to the first embodiment of the present invention.
In the first embodiment of the present invention, the display unit 104 and the operation receiving unit 106 are a display 403. The display 403 is, for example, a touch panel liquid crystal display or plasma display. Further, the display unit 104 may be constituted by a light emitting diode (LED), a Braun tube, or the like. [0027] In the first embodiment, it is assumed that the personal information receiving

unit 101 is a card reader 401, and the user causes the card reader 401 to read the IC card, whereby the personal information receiving unit 101 receives the personal information for identifying an individual.
Note that this is only an example, and the embodiment is not limited to this example. Any configuration can be employed as long as the configuration can be used for identifying an individual. For example, the personal information receiving unit 101 may be a barcode reader and may receive the personal information by reading a barcode, or the personal information receiving unit 101 may be an encryption input device and may receive the personal information by receiving a personal identification number, a password, or the like from the user. In that case, the personal information receiving unit 101 is integrated with the operation receiving unit 106, and the operation receiving unit 106 receives, from the user, an instruction to display an input screen for a personal identification number or a password on the display 403, and causes the display 403 to display a screen based on the received instruction. Then, the operation receiving unit 106 receives an operation of the user from the display 403, and outputs the received information to the personal information receiving unit 101, as the personal information.
In addition, the personal information receiving unit 101 may be a receiver capable of performing wireless communication with an information terminal owned by a user, such as a smartphone and may receive the personal information by receiving information from the information terminal owned by the user, or the personal information receiving unit 101 may be a face authentication camera and may receive the personal information by acquiring a face image of the user. Alternatively, the personal information receiving unit 101 may be a fingerprint authentication device and may receive the personal information from a fingerprint pressed by the user.

[0028] The functions of the personal authentication unit 102, the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107 are implemented by a processing circuit 402. That is, the destination floor registration device 1 includes the processing circuit 402 for performing processing for user authentication, performing estimation of the destination floor candidate of the user, and controlling a display operation of the destination floor candidate, and the processing circuit 402 for controlling a registration information creation operation based on the received destination floor. The processing circuit 402 may be dedicated hardware as illustrated in FIG. 3 A or a central processing unit (CPU) 406 that executes a program stored in a memory 407 as illustrated in FIG. 3B.
[0029] In a case where the processing circuit 402 is dedicated hardware, the processing circuit corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a combination thereof.
[0030] In a case where the processing circuit 402 is the CPU 406, the functions of the personal authentication unit 102, the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107 are implemented by software, firmware, or a combination of software and firmware. That is, the personal authentication unit 102, the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107 are implemented by the CPU 406 that executes a program stored in a hard disk drive (HDD) 404, the memory 407, or the like, and a processing circuit such as a system large-scale integration (LSI). Further, the program stored in the HDD 404, the memory 407, or the like causes a computer to execute procedures and methods of the personal

authentication unit 102, the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107. Here, the memory 407 corresponds to, for example, a nonvolatile or volatile semiconductor memory such as a random access memory (RAM), a read only memory (ROM), a flash memory, an erasable programmable read only memory (EPROM), an electrically erasable programmable read only memory (EEPROM), a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a digital versatile disk (DVD). [0031] Note that some of the functions of the personal authentication unit 102, the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107 may be implemented by dedicated hardware and other functions may be implemented by software or firmware. For example, the function of the personal authentication unit 102 can be implemented by the processing circuit 402 as dedicated hardware, and the functions of the display control unit 105, the destination floor estimating unit 110, and the registration information creating unit 107 can be implemented by the processing circuit by reading and executing the program stored in the memory 407.
[0032] The personal information DB 103 uses the HDD 404. Note that this is merely an example, and the personal information DB 103 may be configured with a DVD, the memory 407, and the like.
The registration information transmitting unit 108 and the elevator-unit instruction receiving unit 109 use a communication I/F 405. Note that this is merely an example, and the registration information transmitting unit 108 and the elevator-unit instruction receiving unit 109 may be configured with other hardware. [0033] Here, FIG. 4 is an external view of the destination floor registration device 1 according to the first embodiment.

As illustrated in FIG. 4, the destination floor registration device 1 has the housing and displays either the destination floor candidates or the numeric keys on the display 403. Note that FIG. 4 illustrates a case where the destination floor candidates are displayed.
The personal information is received as the user causes the card reader 401 provided in the housing to read the IC card owned by the user himself/herself, for example.
Note that the destination floor registration device 1 may be mounted on a base installed on the floor of the elevator hall or may be attached to a wall of an elevator hall. Further, the housing of the destination floor registration device 1 is not limited to the shape as illustrated in FIG. 4. [0034] An operation will be described.
FIG. 5 is a flowchart for describing an operation of the destination floor registration device 1 according to the first embodiment.
The personal information receiving unit 101 waits until receiving the personal information for identifying an individual from the user (in the case of "NO" in step ST601). When receiving the personal information for identifying an individual from the user (in the case of "YES" in the step ST601), the personal information receiving unit 101 outputs the received personal information to the personal authentication unit 102 (step ST601).
The operation of this step ST601 will be described with a specific example.
For example, in a case of a user who is not the user using the building every day and not an employee who works in the building but a mere visitor or the like from the outside, and does not carry a medium capable of specifying an individual, such as an IC card, the user performs a touch operation on the display 403 as the display unit 104

or presses a button indicating a non-IC card holder (not illustrated) provided on the destination floor registration device 1. The operation receiving unit 106 receives the touch operation or the like of the user, and outputs information indicating that the user is a non-IC card holder to the personal information receiving unit 101, as the personal information. The personal information receiving unit 101 may just determine that the personal information is received by acquiring the personal information from the operation receiving unit 106.
Note that this is merely an example, and the operation receiving unit 106 may receive the information indicating that the user is a non-IC card holder from the user by another method. When receiving an input of the information for identifying an individual such as a personal ID, the operation receiving unit 106 may output the received information to the personal information receiving unit 101, as the personal information.
[0035] Further, for example, in a case where the user owns a medium capable of specifying an individual such as an IC card, the user causes the card reader 401 to read the IC card, for example, whereby the personal information receiving unit 101 acquires the personal information for identifying an individual, that is, here, an IC card number owned by the user. [0036] Referring back to the flowchart of FIG. 5.
The personal authentication unit 102 acquires the personal information output by the personal information receiving unit 101 in step ST601 and performs authentication of the individual by comparing the personal information stored in the personal information DB 103 (step ST602). [0037] Here, the operation of step ST602 will be specifically described.
FIG. 6 is a diagram illustrating an example of content of personal information

stored in the personal information DB 103 in the first embodiment.
In the personal information DB 103, information of users who use the building, for example, information of employees who works in the building is stored for each individual.
Here, as illustrated in FIG. 6, at least a personal ID, an IC card number, a department, and an office floor of the department are associated and registered in the personal information DB 103.
The personal authentication unit 102 compares the IC card number of the user acquired as the personal information in step ST601 with the IC card number stored in the personal information DB 103, and performs authentication of the individual of the user. For example, when the user's IC card number is " 11111", the personal authentication unit 102 authenticates that the user is a person with a personal ID "10001" and belonging to the general affairs department on the 4th floor. Then, the personal authentication unit 102 outputs the authenticated personal ID and office floor information to the destination floor estimating unit 110 as personal authentication result information.
Further, in a case where the user's IC card number acquired as the personal information in step ST601 is not matched with the IC card number stored in the personal information DB 103, the personal authentication unit 102 outputs information indicating personal authentication failure to the destination floor estimating unit 110, as the personal authentication result information. For example, in a case where the user is not an employee who works in the building and is a visitor from an outside, and does not have an IC card or a case where an IC card that the user has is invalid, the comparison with the personal information stored in the personal information DB 103 cannot be performed, and thus the personal authentication unit 102 outputs the

information indicating personal authentication failure to the destination floor estimating unit 110, as the personal authentication result information.
[0038] The destination floor estimating unit 110 determines whether the personal authentication has succeeded in the personal authentication unit 102 on the basis of the personal authentication result information acquired from the personal authentication unit 102 (step ST603). Note that the destination floor estimating unit 110 may just determine whether the personal authentication has succeeded in the personal authentication unit 102 from content of the acquired personal authentication result information. To be specific, here, when information of the authenticated personal ID and office floor information are included, determination that the personal authentication has succeeded is made. When the information indicates the personal authentication failure, determination that the personal authentication has failed, that is, the user cannot be identified is made.
[0039] In step ST603, when it is determined that the personal authentication has succeeded (in the case of "YES" in step ST603), the destination floor estimating unit 110 determines the destination floor candidate to be presented to the user, from the personal authentication result information of the user, which has been acquired from the personal authentication unit 102, and the information of a situation at the time of use, and outputs information of the determined destination floor candidate to the display control unit 105 (step ST604).
[0040] On the other hand, when it is determined that individual authentication has failed in step ST603 ("NO" in step ST603), the destination floor estimating unit 110 determines the destination floor candidate to be presented to the user from the information of a situation at the time of using the elevator, and outputs information of the determined destination floor candidate to the display control unit 105 (step ST605).

Note that the destination floor candidate determined by the destination floor estimating unit 110 in steps ST604 and ST605 follows a condition determined in advance for destination floor estimation, and the destination floor estimating unit 110 appropriately acquires the information of a situation at the time of use in accordance with the condition. Further, it is assumed that the number of destination floor candidates determined by the destination floor estimating unit 110 is also determined in advance.
The specific operation of the destination floor candidate determination by the destination floor estimating unit 110 in steps ST604 and ST605 will be described below with a specific example.
[0041] The display control unit 105 causes the display unit 104 to display the information of the destination floor candidate acquired from the destination floor estimating unit 110 in step ST604 or step ST605 (step ST606).
Here, an example of the screen displayed on the display unit 104 is as illustrated in FIG. 4.
FIG. 4 illustrates an example in which display of "4", "10", and "LOBBY" indicating the destination floor candidates "the 4th floor, the 10th floor, and the entrance floor", and "OTHER" that is switching display for switching the screen to a screen for inputting the destination floor when a user desires to register a floor other than the destination floor candidates are displayed on the display 403 as the display unit 104. [0042] The user checks the displayed content and if there is a desired destination floor in the displayed destination floors, the user registers the destination floor by touching the corresponding destination floor.
That is, for example, assuming that the screen as illustrated in FIG. 4 is displayed at step ST606, and if a desired destination floor corresponds to the 4th, 10th,

or lobby floors, the user registers the desired destination floor by touching the destination floor candidate.
[0043] In this way, the destination floors highly likely to match the user's intention from among all the floors in the building are estimated, and only the estimated destination floors are displayed, whereby the number of floors displayed on the display unit 104 can be reduced, and the user can complete the operation of the destination floor registration with fewer procedures. Completion of the operation of the destination floor registration with fewer steps can reduce the user's distraction. Further, reduction of the user's distraction makes the operation time of the user short and enables a larger number of passengers to perform the operation of the destination floor registration with one destination floor registration device 1, whereby to reduce the waiting time when a large number of people are in the landing.
[0044] In addition, the destination floor candidates highly likely to match the user's intension are narrowed down, and only the information highly likely to be selected and operated by the user is displayed on the display unit 104. Therefore, the table of unnecessary information for the user can be reduced and the display area of the destination floor registration device 1 can be made small. Therefore, the display device of the destination floor registration device 1 can be downsized. In general, a display device smaller than a large display device is inexpensive. Also, the power consumption is also generally reduced. Therefore, the cost and the power consumption can be reduced.
[0045] In addition, by use of a small display device, the size of the destination floor registration device 1 as a whole can be made smaller than conventional ones, and the destination floor registration device 1 is less likely to be restricted by buildings and walls that are installation places.

[0046] Note that if there is no desired destination floor in the displayed destination floors, the user touches "OTHER" that is switching display.
[0047] The operation receiving unit 106 determines whether an operation of selecting the destination floor candidate has been received from the user (step ST607). Here, to be specific, the operation receiving unit 106 determines whether there has been any touch operation of "4", "10", and "LOBBY" displayed on the display 403 as the display unit 104 from the user.
[0048] When it is determined that the operation of selecting the destination floor candidate has been received from the user in step ST607 (in the case of "YES" in step ST607), the operation receiving unit 106 outputs information of the destination floor candidate received by the selecting operation to the registration information creating unit 107, as the destination floor selection information, on the basis of the received operation of selecting the destination floor candidate.
[0049] On the other hand, when it is determined that the operation of selecting the destination floor candidate has not been received from the user in step ST607 (in the case of "NO" in step ST607), the operation receiving unit 106 determines whether an operation of selecting the switching display has been received (step ST612).
When it is determined that the operation of selecting the switching display has not been received in step ST612 (in the case of "NO" in step ST612), the processing returns to step ST607.
When the operation of selecting the switching display has been received in step ST612 (in the case of "YES" in step ST612), that is, when the user has performed the touch operation on display of "OTHER", the operation receiving unit 106 outputs switching display selecting information to the display control unit 105 on the basis of the received operation of selecting the switching display. That is, the user determines

that there is no desired destination floor in the destination floor candidates presented in step ST606, and instructs the switching of a screen display by the operation of selecting the switching display to call numeric keys in order to input another floor not displayed as the destination floor candidates.
[0050] The display control unit 105 causes the display unit 104 to display the numeric keys on the basis of the switching display selection information output by the operation receiving unit 106 (step ST613).
Here, FIG. 7 is a diagram illustrating an example of a state in which the display control unit 105 causes the display unit 104 to display the numerical keys in step ST613.
The display control unit 105 causes the display 403 as the display unit 104 to switch the display screen from the state where the destination floor candidates are displayed as illustrated in FIG. 4 to a state where the numeric keys are displayed as illustrated in FIG. 7.
The user registers the destination floor by touching the numeric keys to input the desired destination floor.
[0051] In this manner, the numeric keys are displayed on the display unit 104 by the display control unit 105 only when there is no user's desired destination floor in the destination floor candidate. Therefore, the display unit 104 does not need to display the destination floor candidates and the numeric keys at the same time.
Therefore, in the display device, there is no need to prepare an area for displaying both the destination floor candidates and the numeric keys, or an area provided with the numeric keys for determining the destination floor separately from the destination floor candidate display screen. Therefore, the display device of the destination floor registration device 1 can be reduced in size, leading to downsizing of the destination floor registration device 1 as a whole.

[0052] The operation receiving unit 106 receives an input of the desired destination floor by the touch operation of the numeric keys from the user, and outputs information of the received destination floor to the registration information creating unit 107, as the destination floor selection information (step ST614).
[0053] The registration information creating unit 107 creates registration information on the basis of the destination floor selection information output by the operation receiving unit 106 in step ST607 or ST614 and the information of the floor where the destination floor registration device 1 that has received the operation from the user is installed (step ST608). Here, for example, assuming that the user is on the dining room floor and the destination floor registration is performed from the destination floor registration device 1 installed on the lobby floor. In step ST607, "4" is touched and the 4th floor is selected as the destination floor, the registration information creating unit 107 creates the registration information of a landing call setting the dining room floor as the landing and a destination call setting the 4th floor as the destination floor.
The registration information creating unit 107 transmits the registration information created in step ST608 to the group management control device 2 via the registration information transmitting unit 108 (step ST609). [0054] When receiving the registration information from the destination floor registration device 1, the group management control device 2 allocates an optimum elevator unit from among a plurality of elevators in response to the received registration information, and transmits allocation information of the elevator unit to the destination floor registration device 1 that has transmitted the registration information. [0055] The elevator instruction receiving unit 109 waits to receive the allocation information of the elevator unit to the registration information transmitted in step ST609 from the group management control device 2 (in the case of "NO" in step ST610).

When receiving the allocation information of the elevator unit from the group
management control device 2 (in the case of "YES" in step ST610), the elevator
instruction receiving unit 111 outputs the received allocation information of the elevator
unit to the display control unit 105.
[0056] The display control unit 105 causes the display unit 104 to display the elevator
unit that the user should enter on the basis of the allocation information of the elevator
unit output from the elevator instruction receiving unit 109 (step ST611). To be
specific, for example, here, assuming that a second elevator unit is allocated to the
registration information of the user who has registered the 4th floor as the destination
floor in step ST607, the display control unit 105 causes the display unit 104 to display
an instruction to prompt the user to get on the second elevator unit for the 4th floor, like
"Please get on the second elevator unit".
[0057] The user sees the allocation result of the elevator unit displayed on the display
403 as the display unit 104 in step ST611, the user recognizes the elevator unit that the
user should get on, and waits for arrival of the car of the elevator in front of the elevator
unit.
[0058] The display control unit 105 causes the display unit 104 to display the elevator
unit that the user should get on in step ST611 and then causes the display unit 104 to
display an initial screen after a lapse of a certain period of time, for example.
[0059] Here, a specific operation of the destination floor candidate determination by
the destination floor estimating unit 110 in steps ST604 and ST605 will be described
with a specific example.
First, the operation of step ST604, that is, the operation of the destination floor candidate determination performed by the destination floor estimating unit 110 in a case where it is determined that the individual authentication has succeeded will be described

with a specific example.
As an example, description will be given on the estimation that a user a, who works in a building in which the destination floor registration device 1 is installed and who owns the IC card with an IC card number "11111" illustrated in FIG. 6, performs the landing call and the destination call by the destination floor registration device 1 on May 22, 2015. Further, here, assuming that the information of a time zone at the time of using the elevator is the information of a situation at the time of using the elevator, the condition for the destination floor estimation is set such that the destination floor is estimated on the basis of the time zone, and the time zone is divided into the time of arrival at work (until 10:00), the time of lunch break (11:30 to 13:00), and the time for work (10:00 to 11:30 and 13:00 to 18:00), and the time of going home (after 18:00). Further, the content of the personal information DB 103 is the same as the content illustrated in FIG. 6. Further, as for the time of using the elevator, the destination floor estimating unit 110 acquires, from the operation receiving unit 106, the time when the user has operated the destination floor registration device 1, that is, the time when the operation receiving unit 106 has received the input of the personal information from the user, and determines the aforementioned time as the time when the elevator is used. That is, in the first embodiment, the situation at the point of time when the user has performed the operation of the destination floor registration device 1 is the situation at the time when the elevator is used, and the situation at a point of time when the personal information has been input.
[0060] For example, in a case where the user a operates the destination floor registration device 1 at 8:45 that is in the time zone of the time of arrival at work, the destination floor estimating unit 110 narrows down the destination floor candidates in priority order of the user's office floor as the first, a conference room booked on the day

as the second, and a floor where an event is scheduled on the day as the third. [0061] To be specific, the user a causes the card reader 401 of the destination floor registration device 1, which is the personal information receiving unit 101, to read the IC card owned by the user a, and the personal information receiving unit 101 acquires the IC card number (step ST601). Then, the personal authentication unit 102 compares it with the IC card number stored in the personal information DB 103, and outputs the personal authentication result information authenticating that the user has the personal ID "10001" and is a person belonging to the general affairs department on the 4th floor (step ST603), and the destination floor estimating unit 110 sets the 4th floor as the first destination floor candidate from the personal authentication result information.
Next, the destination floor estimating unit 110 determines whether there is a conference room scheduled for a conference on the day, for the user a, and if there is a conference room scheduled for a conference, the destination floor estimating unit 110 sets the floor of the conference room as the second destination floor candidate. [0062] Whether there is a conference room scheduled for a conference can be determined, for example, by the destination floor estimating unit 110 confirming whether there is a conference room reservation made by the user a, in conjunction with a conference room reservation system. Here, as an example, it is assumed that the destination floor estimating unit 110 confirms the reservation status information (see FIG. 8) managed by the conference room reservation system, and determines whether there is conference room reservation by the user a within one hour from the time when the user has operated the destination floor registration device 1, that is, from the time when the input of the personal information from the user has been received, which has been acquired from the operation receiving unit 106. The conference room reservation by the user a with the personal ID "10001" has been made to a conference room 1001

on the 10th floor at the use start time 9:30 on the use day 2015/05/22, and thus the destination floor estimating unit 110 sets the 10th floor where the conference room is located as the second destination floor candidate.
[0063] Next, the destination floor estimating unit 110 confirms whether there is an event scheduled on the day from event information on a specific date and time acquired from the calendar storage unit (not illustrated), and if there is an event scheduled on the day, the destination floor estimating unit 110 sets the floor where the event is to be held as the third destination floor candidate. Here, assuming that a regular social gathering once a month is scheduled in the dining room from 9:00, the destination floor estimating unit 110 sets the dining room floor as the third destination floor candidate.
Note that the event information of specific date and time stored in the calendar storage unit includes at least information of the scheduled event, the floor where the event is to be held, and the hours for the event. For example, in a case where there is an event scheduled on the day, and the start time of the event is within two hours from the time when the user has operated the destination floor registration device 1, that is, the time when the personal information has been received from the user, which has been acquired from the operation receiving unit 106, the destination floor estimating unit 110 may determine the floor where the event is to be held as the third destination floor candidate.
Further, in a case where the number of the destination floor candidates is less than three, such as when there are no scheduled events on the day, only floors corresponding to the condition determined in advance may be set as the destination floor candidates.
[0064] In this way, when the user a operates the destination floor registration device 1 in the morning time zone, the situation at the time of using the elevator is estimated as

the time of arrival at work, and thus the office floor is estimated as the destination floor in accordance with the attribute of the individual. Further, here, at the same time, when it is clear that a specific floor has a plan at this time, such as a conference, or when a specific event or the like is scheduled as a schedule of the day, the floors are estimated as the destination floors. Note that when to set the time zone of the time of arrival at work in the morning may just be set as appropriate.
[0065] Further, for example, when the user a operates the destination floor registration device 1 at 13:00 that is in the time zone of lunch break, the destination floor estimating unit 110 determines that the user a is at lunch time, and determines the dining room floor and the entrance floor as the first and second destination floor candidates, respectively, assuming that the user a goes out for a meal. Further, the user a may come back to the office once before the lunch, in the case where there is a conference in the morning, and thus the office floor of the user a is determined as the third destination floor candidate. As for the third destination floor candidate, the destination floor estimating unit 110 operates synchronously with the conference room reservation system, or acquire event information of specific date and time, and when there is a reservation of a conference in the morning or when an event is scheduled, the office floor may be set to the destination floor candidate, for example.
Further, as for which of the dining room floor and the entrance floor is prioritized, air temperature information may be acquired from an air temperature sensor (not illustrated), and the dining room floor may be prioritized when the air temperature is equal to or higher than a set temperature or equal to or lower than a set temperature, and the entrance floor may be prioritized when the air temperature falls within a set temperature, as the destination floor candidate. For example, even when the user a usually goes out for lunch, if the temperature at the time of using the elevator is low, the

user a may take lunch inside without eating out on the day. By setting the priority order of the floors as the destination floor candidates on the basis of the air temperature, the destination floor candidates more suitable for the situation at the time of using the elevator can be presented.
[0066] In this way, when the user a operates the destination floor registration device 1 during the time zone of lunch break, it can be estimated that the user a goes out for lunch as the situation at the time of using the elevator, and thus the dining room floor or the entrance floor is estimated as the destination floor. In addition, here, the office floor according to the attribute of the individual is also estimated as the destination floor. Note that when to set the time zone of lunch break may just be set as appropriate. [0067] Further, for example, when the user a operates the destination floor registration device 1 at 18:30 that is in the time zone of going home, the destination floor estimating unit 110 determines the entrance floor and the parking lot as the first and second destination floor candidates, respectively, assuming that the user a is at the time of going home. Further, the user a may stop by the office once after attending a conference or the like before going home, and thus the office floor of the user a is determined as the third destination floor candidate. As for the third destination floor candidate, the destination floor estimating unit 110 operates synchronously with the conference room reservation system, or acquire event information of specific date and time, or acquires the time at which the operation of the destination floor registration device 1 has been performed, from the operation receiving unit 106 or the personal information receiving unit 101, and the office floor may be set to the destination floor candidate when there is reservation of a conference or an event is scheduled 30 minutes before the reception time. [0068] In this way, when the user a operates the destination floor registration device 1

during the time zone of going home, it can be estimated that the user a is going home as the situation at the time of using the elevator, and thus the entrance floor or the parking lot is estimated as the destination floor. In addition, here, the office floor according to the attribute of the individual is also estimated as the destination floor. Note that from when to when being set to the time zone of going home may just be set as appropriate. [0069] In this manner, the destination floor candidates are estimated on the basis of not only the floor that would be registered as the floor in accordance with the attribute of an individual but also the time zone when the destination floor is registered, and are presented. Therefore, the destination floor candidates can be more appropriately presented to the user on the basis of the situation at the time of using the elevator. [0070] Next, the operation of step ST605, that is, the operation of the destination floor candidate determination performed by the destination floor estimating unit 110 when the individual authentication has failed will be described with a specific example.
As an example, description will be given on the estimation that a user b who visits a building that is a complex building having offices, commercial facilities, a theater, and the like, where the destination floor registration device 1 is installed, performs the landing call and the destination call from the destination floor registration device 1 on May 22, 2015. In addition, here, it is assumed that calendar information of whether a holiday or a weekday at the time of using the elevator is the information of a situation at the time of using the elevator, and a condition for destination floor estimation is set such that the destination floor is estimated depending on the holiday or the weekday.
[0071] For example, when the user b operates the destination floor registration device 1 on a holiday, the destination floor estimating unit 110 narrows down the destination floor candidates in priority order of the observatory —► the theater —► the restaurant floor.

When the user operates the destination floor registration device 1 on the holiday, it can be estimated that there is a high possibility of visiting the commercial facility, and thus the observatory, the theater, and the restaurant floor, which are the commercial facilities, are determined as the destination floor candidates. Further, the destination floor estimating unit 110 may acquire the reception time from the operation receiving unit 106, and if the reception time is in the time zone for lunch or dinner, for example, 11:00 to 13:00 or 17:00 to 21:00, the restaurant floor may be preferentially determined as the destination floor candidate. Further, schedule information of the theater may be acquired, and the parking lot or the entrance floor may be determined as the destination floor candidate when it is determined that a performance or a show has ended on the basis of the reception time and the schedule information. [0072] Further, for example, when the user b operates the destination floor registration device 1 on a weekday, the destination floor estimating unit 110 narrows down the destination floor candidates in priority order of the entrance floor of the office in the building —► the lobby —► the rest area.
When the user operates the destination floor registration device 1 on the weekday, it can be estimated that there is a high possibility of visiting the office, and thus the entrance floor of the office in the building, the lobby, and the rest area are determined as the destination floor candidates.
[0073] In this manner, even when the personal authentication has failed, the destination floor candidates are estimated on the basis of the day when the destination floor is registered, and are presented. Therefore, the destination floor candidates can be more appropriately presented to the user on the basis of the situation at the time of using the elevator. [0074] Further, in the above example, the user b who is a visitor to the office has been

described that the individual authentication has failed. However, for example, the personal authentication unit 102 may be able to allow the personal authentication as a specific visitor from information for specifying the individual received by the personal information receiving unit 101. To be specific, for example, an IC card to be lent to a visitor, which includes information as to whether a visitor is the specific visitor, is registered to the personal information DB 103, and whether the visitor is the specific visitor may be determined from an IC card number of the IC card to be lent. For example, in this case, the IC card number of the IC card to be lent to a visitor invited to a conference is registered in advance to the personal information DB 103 by an employee.
Further, the visitor is registered as an attendee to the conference room reservation information that the visitor attends in the conference room reservation system. When the personal authentication unit 102 authenticates the visitor, the destination floor estimating unit 110 may estimate the floor of the conference room to which the visitor is invited as the destination floor candidate.
Also, when the conference to which the visitor is invited has finished, the destination floor estimating unit 110 can determine the end of the conference from that time and estimate the entrance floor as the destination candidate floor.
By doing in this way, the destination floor candidate can be more appropriately presented on the basis of the situation at the time of using the elevator of a visitor as the user, that is, the schedule of the day.
[0075] Further, in the above example, regarding the situation at the time of use, the destination floor estimating unit 110 may determine the situation at the time of use, using the information of the floor where the destination floor registration device 1 has been operated as the information of a situation at the time of use, estimate the

destination floor candidate, and cause the display unit 104 to display the estimated destination floor candidate.
[0076] To be specific, for example, when the personal information receiving unit 101 receives the personal information (in the case of "YES" in step ST601), the destination floor estimating unit 110 estimates the destination floor candidate on the basis of the floor where the destination floor registration device 1 that has received the personal information, that is, the operation, is installed. For example, when the floor where the destination floor registration device 1 is installed is the parking lot floor, a floor of a tenant, which is not the parking lot floor, may be estimated as the destination floor candidate, assuming that the visitor is in a situation of visiting a facility in the building, or when the floor where the destination floor registration device 1 that has received the operation is installed is the floor of a conference room usable by the visitor, the entrance floor may be estimated as the destination floor candidate, assuming that the visitor is in a situation of going home after the conference.
Which floor is estimated as the destination floor candidate by the destination floor estimating unit 110 on the basis of the floor where the destination floor registration device 1 that has received the operation is installed can be appropriately set.
Note that the destination floor estimating unit 110 may acquire the information of the floor where the destination floor registration device 1 that has received the operation is installed from the operation receiving unit 106.
[0077] As described above, in steps ST604 and ST605, the destination floor estimating unit 110 determines the destination floor candidate on the basis of the situation at the time of using the elevator.
Note that, in the above example, the destination floor candidate has been determined on the basis of the information of the time zone or the calendar information

of the holiday or weekday when the destination floor registration device 1 has been operated as the information of a situation at the time of use. However, the embodiment is not limited to the example. For example, the destination floor candidate may be determined on the basis of seasonal information in such a manner that a floor with a pool is determined in summer or a floor with a skate link is determined in winter, or the destination floor candidate may be determined on the basis of weather information in such a manner that an indoor commercial facility is determined when raining or a rooftop floor is determined in a sunny day. Further, for example, on a day when a large party takes place in the building in which the destination floor registration device 1 is installed, a party room may be uniformly determined as the destination floor candidate from the calendar information. When the date operated by the destination floor registration device 1 is a new year's eve, the new year's eve is specified from the calendar information and the floor of the observatory may be uniformly determined as the destination floor candidate.
What information is used to determine the situation at the time of using the elevator and determine the destination floor candidate can be appropriately set in advance as long as the destination floor estimating unit 110 can determine the destination floor candidate from the situation at the time of using the elevator.
Further, the priority order of the floor to be the destination floor candidate is set in advance and can be appropriately set.
In the above-described example, the destination floor estimating unit 110 estimates three destination floor candidates at maximum, but the number of destination floor candidates is not limited thereto. For example, the number of the destination floor candidates may be one, or may be three or more as long as the display area of the display unit 104 is not enlarged due to an increase in the amount of information to be

displayed or does not cause the user to be distracted.
[0078] Further, in the first embodiment, when the switching display has been selected and operated in step ST612 in FIG. 5, the display control unit 105 has cause the display unit 104 to display the numerical keys, prompting the user to input the desired destination floor. However, the embodiment is not limited thereto, and for example, the display control unit 105 may cause the display unit 104 to display a list of all the floors in the building, and the user may select a desired destination floor from the list of the floors. It is sufficient as long as only the necessary information for the user to register the desired destination floor is displayed in a switchable manner. [0079] Further, in the first embodiment, the display unit 104 is the display 403 such as a touch panel liquid crystal display or plasma display. However, the present embodiment is not limited thereto, and the display 403 may not be a touch panel display. In that case, as illustrated in FIG. 9, input buttons 408 corresponding to the destination floor candidates or the switching display are provided beside the display 403 that is the display unit 104 of the destination floor registration device 1, so that the user performs the selection operation of the destination floor or the selection operation of the switching display by pressing the input button 408.
[0080] As described above, according to the first embodiment, the destination floor is estimated in consideration of the attribute of the user and the situation at the time of use and the destination floor candidate, which would be selected by the user, can be more appropriately presented.
[0081] Further, the destination floor registration device 1 according to the first embodiment includes the personal authentication unit 102 and the destination floor estimating unit 110. When the personal authentication unit 102 performs processing for authenticating the individual and outputs the result as personal authentication result

information (step ST601 in FIG. 5), the destination floor estimating unit 110 has the steps (steps ST603 to ST605 in FIG. 6) of determining the destination floor candidate of the user on the basis of the personal authentication result information and the information at a point of time when the operation receiving unit 106 has received the operation of the destination floor registration device 1 from the user, that is, the information of a situation at a point of time when the personal information has been input, and thus the destination floor candidate in consideration of the attribute of the user and the situation at the time of use can be presented.
[0082] Note that the invention of the present application allows modification of an arbitrary configuration element of the embodiment or omission of an arbitrary configuration element of the embodiment within the scope of the invention.
