Description of Embodiments
[0009] Hereinafter, a driving operation management
system, a management server, a terminal device, and a
25 driving operation management method according to
embodiments of the present invention will be described in
detail with reference to the drawings. Note that the
present invention is not limited to the embodiments.
[0010] First Embodiment.
30 FIG. 1 is a block diagram illustrating an example of a
configuration of a driving operation management system 50
according to a first embodiment of the present invention.
FIG. 2 is a diagram illustrating an example of installation
6
of the driving operation management system 50 according to
the first embodiment. Although FIG. 2 illustrates a train
100 of two cars including a first car 101 and a middle car
102, in reality, it is assumed that another middle car 102
5 or a rear car having a structure similar to that of the
first car 101 is also connected to the right side of the
middle car 102. Note that FIG. 2 illustrates integrated
train management apparatuses 30 and 30a separately, but the
present invention is not limited thereto. The integrated
10 train management apparatuses 30 and 30a may be integrated.
Hereinafter, the first car 101 and the middle car 102 of
the train 100 will be described. The driving operation
management system 50 includes a biosensor 10, a terminal
device 20, the integrated train management apparatus 30,
15 and a management server 40.
[0011] The biosensor 10 is worn on an operator 1 who
operates the train 100. The biosensor 10 includes a
biological information acquisition unit 11. The biological
information acquisition unit 11 detects and acquires
20 biological information of the operator 1 inside and outside
the train 100. The biological information is, for example,
mental and physical information such as a heart rate, an
amount of perspiration, a line of sight, movement of an
eyeball, brain waves, blood pressure, a body temperature,
25 and a blood glucose level. Specifically, the biosensor 10
is assumed to be a heart rate meter, a thermometer, or the
like having a communication function, but is not limited
thereto. The biosensor 10 may be an imaging device such as
a camera capable of detecting blink speed of the operator 1.
30 The driving operation management system 50 may also include
a plurality of the biosensors 10 of different types, or a
plurality of the biosensors 10 of the same type. The
biological information acquisition unit 11 causes an
7
operator information accumulation unit 21 of the terminal
device 20, which will be described later, to accumulate the
detected biological information as operator information.
Communication between the biosensor 10 and the terminal
5 device 20 may be wireless communication or wired
communication. The biosensor 10 is assumed to have
identification information such as a model number that can
be uniquely identified.
[0012] The terminal device 20 is a communication device
10 carried by the operator 1 inside and outside the train 100.
Specifically, the terminal device 20 is a communication
device such as a tablet or a smartphone capable of wireless
communication or wired communication with the biosensor 10
and the management server 40. The terminal device 20
15 includes the operator information accumulation unit 21 and
a notification unit 22. The operator information
accumulation unit 21 accumulates the operator information
that is information indicating a state of the operator 1 of
the train 100. In the first embodiment, the operator
20 information accumulation unit 21 accumulates, as the
operator information, the biological information of the
operator 1 acquired by the biological information
acquisition unit 11 of the biosensor 10. In accordance
with a determination result by a determination unit 46 of
25 the management server 40 described later, the notification
unit 22 notifies the operator 1 of the determination result,
that is, an operating state of the operator 1 by sound,
screen display, or the like. The notification unit 22 may
be installed on a cab 60 of the train 100 instead of the
30 terminal device 20. Note that in FIG. 2, the terminal
device 20 is emphasized and illustrated in a large size for
easy understanding of an image of the appearance of the
terminal device 20, and in reality has the size that can be
8
carried in the train 100 by the operator 1.
[0013] The integrated train management apparatus 30 is,
for example, an integrated train management system
installed on the train 100. In the example of FIG. 2, the
5 integrated train management apparatus 30 is assumed to be a
central apparatus of the integrated train management system
installed on the first car 101 of the train 100. Also in
the train 100, it is assumed that the integrated train
management apparatus 30a, which is a terminal device of the
10 integrated train management system, is installed on the
middle car 102. The integrated train management apparatus
30 is connected to each of the cab 60, a No Fuse Breaker
(NFB) 61, a Remote Input Output (RIO) 62, and a Brake
Electronic Control Unit (BECU) 64, thereby controlling the
15 operation of each device and monitoring the operating state
of each device. The integrated train management apparatus
30a is connected to each of an RIO 63, BECUs 65 and 66, and
a Variable Voltage Variable Frequency (VVVF) 67, thereby
controlling the operation of each device and monitoring the
20 operating state of each device. In the example of FIG. 2,
the integrated train management apparatus 30 acquires a
control state of each device installed on the middle car
102 from the integrated train management apparatus 30a, and
manages a control state of the entire train 100. Note that
25 in FIG. 2, the devices connected to the integrated train
management apparatuses 30 and 30a are merely examples, and
are not limited thereto. Moreover, in FIG. 2, the
operation of each device is controlled and monitored by the
integrated train management apparatuses 30 and 30a, but the
30 present invention is not limited thereto as long as
information on the devices installed on the train can be
acquired.
[0014] The integrated train management apparatus 30
9
includes a mobile object information acquisition unit 31
and a driving operation reception unit 32. The mobile
object information acquisition unit 31 acquires mobile
object information that is information on a service state
5 of the train 100 while the train 100 is in service. The
mobile object information is, for example, information such
as a train speed, an air-conditioning temperature, or the
number of passengers regarding the train 100. The driving
operation reception unit 32 receives a driving operation
10 from the outside, specifically, the operator 1. The
driving operation includes power running, braking, button
operation, and the like.
[0015] The management server 40 is installed on the
train 100. The present embodiment describes a case where
15 the management server 40 is installed on the train 100,
that is, on a car as an example, but the present invention
is not limited thereto. The driving operation management
system 50 may be in a form in which the management server
40 is installed on the ground. The management server 40
20 includes a service information management unit 41, a
service information accumulation unit 42, a determination
logic setting unit 43, a determination logic accumulation
unit 44, an individual identification unit 45, and the
determination unit 46.
25 [0016] The service information management unit 41
acquires the operator information from the operator
information accumulation unit 21 of the terminal device 20,
acquires the mobile object information from the mobile
object information acquisition unit 31 of the integrated
30 train management apparatus 30, and acquires operation
information indicating the driving operation received by
the driving operation reception unit 32 from the driving
operation reception unit 32 of the integrated train
10
management apparatus 30. The service information
management unit 41 associates the operator information with
at least one of the mobile object information or the
operation information, and causes the service information
5 accumulation unit 42 to accumulate the information as
service information. That is, the service information
management unit 41 may associate the operator information,
the mobile object information, and the operation
information and cause the service information accumulation
10 unit 42 to accumulate the information as the service
information, may associate the operator information and the
mobile object information and cause the service information
accumulation unit 42 to accumulate the information as the
service information, or may associate the operator
15 information and the operation information and cause the
service information accumulation unit 42 to accumulate the
information as the service information. The service
information is information related to the state of each
device installed on the train 100 that is in service and
20 the state of the operator 1 during service and out of
service. Communication between the management server 40
and each of the terminal device 20 and the integrated train
management apparatus 30 may be wireless communication or
wired communication. Note that when installed on the
25 ground, the management server 40 communicates with the
terminal device 20 and the integrated train management
apparatus 30 by wireless communication.
[0017] The service information accumulation unit 42
accumulates the service information associated by the
30 service information management unit 41. FIG. 3 is a table
illustrating an example of the service information
accumulated in the service information accumulation unit 42
of the management server 40 according to the first
11
embodiment. The example of FIG. 3 indicates that, for each
acquired date and time, the service information
accumulation unit 42 accumulates information on an operator
identifier (ID) for identifying the operator 1 currently
5 operating the train 100, a speed of the train 100, a power
running state of the train 100, a temperature around the
train 100, and a heart rate of the operator 1 as the
service information. Here, the information on the operator
ID, the speed, and the temperature is information acquired
10 from the mobile object information acquisition unit 31 by
the service information management unit 41, the information
on the power running is information acquired from the
driving operation reception unit 32 by the service
information management unit 41, and the information on the
15 heart rate is information acquired from the operator
information accumulation unit 21 by the service information
management unit 41. In the example of FIG. 3, the service
information management unit 41 causes the service
information accumulation unit 42 to accumulate the acquired
20 information as the service information in association with
the acquisition date and time. FIG. 3 illustrates the
example in which the service information management unit 41
associates the operator information, the mobile object
information, and the operation information as the service
25 information.
[0018] The individual identification unit 45 identifies
the operator 1 who is currently operating the train 100 on
the basis of the information acquired by the service
information management unit 41. Among the information
30 acquired by the service information management unit 41, for
example, for the operator information, the individual
identification unit 45 identifies the operator 1 by the
type, model number, or the like of the biosensor 10, or
12
identifies the operator 1 by the operator ID or the like
for the mobile object information and the operation
information. As a result, the individual identification
unit 45 can determine from which operator 1 each
5 information acquired by the service information management
unit 41 has been acquired.
[0019] The determination logic setting unit 43 sets a
determination logic for the determination unit 46 to
determine the operating state of the operator 1 on the
10 basis of the service information accumulated in the service
information accumulation unit 42. In addition, the
determination logic setting unit 43 updates the
determination logic accumulated in the determination logic
accumulation unit 44 on the basis of the service
15 information accumulated in the service information
accumulation unit 42. Determining the operating state of
the operator 1 is to predict the occurrence of a human
error by the operator 1. The human error is, for example,
a violation such as overrun of the train 100 by the
20 operator 1 or overspeed of the train 100 by the operator 1.
When such a human error occurs, the operator 1 may perform
an operation such as abrupt steering or hard braking, which
may affect the ride quality or the like of the passengers
on the train 100. Therefore, predicting the occurrence of
25 a human error, that is, determining the operating state of
the operator 1, is an important operation in the regular
service of the train 100. When setting and updating the
determination logic, the determination logic setting unit
43 sets and updates the determination logic for each
30 operator 1 on the basis of an identification result by the
individual identification unit 45. That is, the
determination logic setting unit 43 sets and updates the
determination logic for each operator 1 by preferentially
13
adopting the service information acquired from the same
operator 1 and accumulated in the service information
accumulation unit 42.
[0020] Note that when the determination logic setting
5 unit 43 sets the determination logic on the basis of the
service information accumulated in the service information
accumulation unit 42, a designer or the like sets the
determination logic for a phenomenon subjected to
determination of the operating state of the operator 1 by
10 the determination unit 46. For example, in order to
determine the possibility of overspeed of the train 100 in
the determination unit 46, the designer sets information
indicating that a state of “○○” km/h or faster is a state
of overspeed. In addition, in order to determine the
15 possibility of overrun of the train 100 in the
determination unit 46, the designer sets information
indicating that the train is in an overrun state when going
beyond a prescribed stop position by “××” meters or more.
The determination logic setting unit 43 can set the
20 determination logic by detecting a feature value or the
like from the service information when the phenomenon
occurs, on the basis of the information set by the designer.
A specific example of the determination logic will be
described later.
25 [0021] The determination logic accumulation unit 44
accumulates the determination logic set or updated by the
determination logic setting unit 43.
[0022] The determination unit 46 determines the
operating state of the operator 1 using the determination
30 logic accumulated in the determination logic accumulation
unit 44. Specifically, the determination unit 46
determines the possibility of occurrence of a human error
by the operator 1 from the current service information
14
acquired by the service information management unit 41 and
the determination logic accumulated in the determination
logic accumulation unit 44. The determination unit 46
determines the operating state of the operator 1 by
5 performing individual identification on the service
information on the basis of the identification result by
the individual identification unit 45, and preferentially
acquiring the determination logic of the operator 1 from
the determination logic accumulation unit 44. The
10 determination unit 46 can determine the operating state
according to each operator 1 by using the determination
logic for each operator 1.
[0023] Note that the arrangement of the components of
the driving operation management system 50 illustrated in
15 FIG. 1 is an example, and the present invention is not
limited thereto. For example, the management server 40 may
include the operator information accumulation unit 21 and
the notification unit 22.
[0024] Next, an operation of the driving operation
20 management system 50 will be described. First, an
operation in which the driving operation management system
50 determines the operating state of the operator 1 of the
train 100 will be described. FIG. 4 is a flowchart
illustrating the operation in which the driving operation
25 management system 50 according to the first embodiment
determines the operating state of the operator 1 of the
train 100. In the driving operation management system 50,
the service information management unit 41 of the
management server 40 acquires the service information (step
30 S1). Specifically, the service information management unit
41 acquires the mobile object information from the mobile
object information acquisition unit 31, acquires the
operation information from the driving operation reception
15
unit 32, and acquires the operator information from the
operator information accumulation unit 21.
[0025] The determination unit 46 determines the
operating state of the operator 1 using the service
5 information acquired by the service information management
unit 41 (step S2). Specifically, the determination unit 46
predicts the occurrence of a human error by the operator 1
as described above. Here, first, the individual
identification unit 45 identifies an individual for the
10 service information acquired by the service information
management unit 41. The determination unit 46 acquires the
determination logic of the operator 1 from the
determination logic accumulation unit 44 on the basis of
the identification result by the individual identification
15 unit 45.
[0026] A specific example of determining the operating
state of the operator 1 in the determination unit 46 will
be described. For example, it is assumed that the blood
glucose level and the blood pressure are detected as the
20 biological information of the operator 1, and a
determination logic of “determination logic #1: when the
blood glucose level and the blood pressure are low,
drowsiness tends to be high so that drowsy driving may
occur” is accumulated in the determination logic
25 accumulation unit 44. When detecting that the blood
glucose level of the operator 1 is lower than the average
and the blood pressure is also lower than the average in
the service information acquired by the service information
management unit 41, the determination unit 46 extracts the
30 determination logic #1 matching the detected phenomenon
from the determination logic accumulation unit 44. The
determination unit 46 determines a determination level from
the actual blood glucose level and blood pressure. The
16
determination level is, for example, a specific numerical
value, and varies depending on a difference between the
numerical value indicated by the determination logic and
the numerical value indicated by the service information.
5 The determination unit 46 outputs the determined
determination level to the notification unit 22 as a
determination result.
[0027] The notification unit 22 notifies the operator 1
of the determination result acquired from the determination
10 unit 46 of the management server 40 by a method such as
sound or screen display (step S3). It is assumed that the
content of notification made according to the determination
result is stored in the notification unit 22 in advance.
FIG. 5 is a table illustrating an example of the content of
15 the notification made by the terminal device 20 of the
driving operation management system 50 according to the
first embodiment. For example, in a case where the
determination result by the determination unit 46 of the
management server 40 indicates the operating state of the
20 operator 1 by the determination level that is a numerical
value, it is assumed that the notification unit 22 stores
information on a notification method for each determination
level. In the example of FIG. 5, it is assumed that the
larger the numerical value of the determination level, the
25 higher the probability of occurrence of a human error by
the operator 1. In a case where the determination level by
the determination unit 46 is “100”, the notification unit
22 makes notification by sound with the content of “sound 2”
and also makes notification by screen display with the
30 content of “alert Lv. 3”. As a result, the operator 1 can
grasp the current operating state by checking the content
of the notification by the notification unit 22.
[0028] Note that, in the driving operation management
17
system 50, in a case where a conductor is on board the
train 100 and carries the terminal device 20 or a device
equivalent to the terminal device 20, the determination
unit 46 may also notify the device carried by the conductor
5 of the determination result. As a result, the conductor on
board the train 100 can also grasp the operating state of
the operator 1.
[0029] Next, an operation in which the driving operation
management system 50 updates the determination logic
10 accumulated in the determination logic accumulation unit 44
will be described. FIG. 6 is a flowchart illustrating the
operation in which the driving operation management system
50 according to the first embodiment updates the
determination logic. In the driving operation management
15 system 50, the service information management unit 41 of
the management server 40 acquires the service information
(step S11). Specifically, the service information
management unit 41 acquires the mobile object information
from the mobile object information acquisition unit 31,
20 acquires the operation information from the driving
operation reception unit 32, and acquires the operator
information from the operator information accumulation unit
21. The service information management unit 41 associates
the acquired information with one another and causes the
25 service information accumulation unit 42 to accumulate the
information as the service information (step S12).
[0030] The determination logic setting unit 43 updates
the determination logic accumulated in the determination
logic accumulation unit 44 using the service information
30 accumulated in the service information accumulation unit 42
(step S13). As described above, the determination logic
setting unit 43 performs individual identification on the
service information accumulated in the service information
18
accumulation unit 42, and preferentially uses the service
information for the identified operator 1 when updating the
determination logic of each operator 1. The determination
logic setting unit 43 can also reflect a common
5 characteristic not related to the operator 1 in the
determination logic by using the service information
acquired from other than the operator 1. Specifically, the
determination logic setting unit 43 can automatically
update the determination logic by using artificial
10 intelligence (AI) technology, deep learning, or the like,
but may update the determination logic by receiving a
manual operation. The determination logic setting unit 43
automatically updates the determination logic at a
predetermined timing. The predetermined timing may be, for
15 example, a time interval such as “every 10 seconds” or may
be when an event such as “arriving at the station” occurs,
but is not limited thereto.
[0031] An example of updating a specific determination
logic in the determination logic setting unit 43 will be
20 described. For example, it is assumed that a determination
logic of “determination logic #2: there is a possibility of
overspeed when the heart rate of the operator 1 is 100 or
higher” is accumulated in the determination logic
accumulation unit 44. When overspeed is detected in speed
25 information in the mobile object information acquired from
the train 100, the determination logic setting unit 43
checks the service information when the overspeed is
detected that is accumulated in the service information
accumulation unit 42. When the heart rate of the operator
30 1 is 90 in the service information that has been checked,
the determination logic setting unit 43 updates the
determination logic accumulated in the determination logic
accumulation unit 44 to “determination logic #2: there is a
19
possibility of overspeed when the heart rate of the
operator 1 is 90 or higher”. As a result, the
determination unit 46 can improve the accuracy of
determining the occurrence of a human error by the operator
5 1 by using the updated determination logic.
[0032] Note that as illustrated in FIG. 2, in the
present embodiment, the management server 40 is installed
on the train 100. Therefore, when there is a plurality of
the trains 100, the service information accumulation unit
10 42 and the determination logic accumulation unit 44
included in the management server 40 on each train 100 may
accumulate different information, specifically, the service
information and the determination logic having different
content. Moreover, in a case where a certain operator 1
15 boards a plurality of different trains 100 of the same type,
each train 100 needs to start from the setting of the
determination logic for the operator 1 who boards the train
for the first time. Thus, the service information and the
information of the determination logic accumulated by the
20 management server 40 may be shared or transferred between
the trains 100. Sharing or transferring of the information
between the trains 100 may be performed by the trains 100
directly performing wireless communication or wired
communication to transmit and receive the information, may
25 be performed via a ground system not illustrated, or may be
performed via a storage medium not illustrated.
[0033] Next, a hardware configuration of the driving
operation management system 50 will be described. In the
driving operation management system 50, the biosensor 10
30 including the biological information acquisition unit 11 is
a general sensor such as a heart rate meter as described
above. In the terminal device 20, the notification unit 22
is a monitor such as a liquid crystal display (LCD), a
20
device that outputs sound, or the like for notifying the
operator 1 or the like of the determination result by the
determination unit 46. The operator information
accumulation unit 21 is implemented by processing circuitry.
5 The integrated train management apparatus 30 including the
mobile object information acquisition unit 31 and the
driving operation reception unit 32 is a general integrated
train management system as described above. In the
management server 40, the service information accumulation
10 unit 42 and the determination logic accumulation unit 44
are memories. The service information management unit 41,
the determination logic setting unit 43, the individual
identification unit 45, and the determination unit 46 are
implemented by processing circuitry. The processing
15 circuitry may include a memory and a processor executing
programs stored in the memory, or may include dedicated
hardware.
[0034] FIG. 7 is a diagram illustrating an example of a
case where the processing circuitry of the management
20 server 40 or the like according to the first embodiment
includes a processor and a memory. When the processing
circuitry includes a processor 91 and a memory 92, each
function of the processing circuitry of the management
server 40 or the like is implemented by software, firmware,
25 or a combination of software and firmware. The software or
firmware is described as programs and stored in the memory
92. The processing circuitry implements each function by
the processor 91 reading and executing the programs stored
in the memory 92. That is, the processing circuitry
30 includes the memory 92 for storing the programs that result
in the execution of the processing of the management server
40 or the like. It can also be said that these programs
cause a computer to execute the procedure and method
21
related to the management server 40 or the like.
[0035] Here, the processor 91 may be a central
processing unit (CPU), a processing unit, an arithmetic
unit, a microprocessor, a microcomputer, a digital signal
5 processor (DSP), or the like. The memory 92 corresponds to,
for example, a non-volatile or volatile semiconductor
memory such as a random access memory (RAM), a read only
memory (ROM), a flash memory, an erasable programmable ROM
(EPROM), or an electrically EPROM (EEPROM (registered
10 trademark)), a magnetic disk, a flexible disk, an optical
disk, a compact disc, a mini disc, a digital versatile disc
(DVD), or the like.
[0036] FIG. 8 is a diagram illustrating an example of a
case where the processing circuitry of the management
15 server 40 or the like according to the first embodiment
includes dedicated hardware. When the processing circuitry
includes dedicated hardware, processing circuitry 93
illustrated in FIG. 8 corresponds to a single circuit, a
complex circuit, a programmed processor, a parallel20 programmed processor, an application specific integrated
circuit (ASIC), a field programmable gate array (FPGA), or
a combination of those, for example. The functions of the
management server 40 or the like may be implemented
individually or collectively by the processing circuitry 93.
25 [0037] Note that the functions of the management server
40 or the like may be implemented partly by dedicated
hardware and partly by software or firmware. The
processing circuitry can thus implement the aforementioned
functions by the dedicated hardware, software, firmware, or
30 a combination of these.
[0038] As described above, according to the present
embodiment, the driving operation management system 50
combines the biological information of the operator 1 who
22
is driving with the service information that can be
acquired from the train 100, thereby being able to predict
the occurrence of a human error by the operator 1 and avoid
the occurrence of a human error by notifying the operator 1
5 of the prediction. Moreover, the driving operation
management system 50 quickly detects poor physical
condition of the operator 1 such as a sudden illness or
seizure and notifies the conductor or the ground system of
the detected physical condition, thereby being able to more
10 reliably deal with the situation. Furthermore, the driving
operation management system 50 updates the determination
logic by performing individual identification, and can thus
perform the determination in consideration of individual
differences. The driving operation management system 50
15 can also collect and accumulate the operator information
outside the train 100 by separating the operator
information accumulation unit 21 from the management server
40. In addition, the driving operation management system
50 can use the biological information acquired when a
20 different train 100 is operated as common information when
another train 100 is operated. Therefore, the driving
operation management system 50 can improve the accuracy of
determining the operating state of the operator 1 who
operates the train 100.
25 [0039] Second Embodiment.
As the operator information, a second embodiment
further uses operator behavior information obtained by
detecting a motion of the operator 1 while he operates the
train. Differences from the first embodiment will be
30 described.
[0040] FIG. 9 is a block diagram illustrating an example
of a configuration of a driving operation management system
50a according to the second embodiment. The driving
23
operation management system 50a is obtained by replacing
the terminal device 20 in the driving operation management
system 50 of the first embodiment illustrated in FIG. 1
with a terminal device 20a. The terminal device 20a
5 includes an operator information accumulation unit 21a, the
notification unit 22, and an operator behavior detection
unit 23. The operator behavior detection unit 23 detects a
motion of the operator 1 and causes the operator
information accumulation unit 21a to accumulate operator
10 behavior information, which is information on the detected
motion of the operator 1, as the operator information. The
motion of the operator 1 includes, but is not limited to,
pointing and calling by the operator 1, a line of sight of
the operator 1, and the like. The operator behavior
15 detection unit 23 is, for example, a camera capable of
capturing the motion of the operator 1. The operator
information accumulation unit 21a includes the function of
the operator information accumulation unit 21 of the first
embodiment and the function of accumulating the operator
20 behavior information as the operator information. The
operator information accumulation unit 21a outputs, as the
operator information, biological information acquired from
the biosensor 10 and the operator behavior information
acquired from the operator behavior detection unit 23 to
25 the service information management unit 41.
[0041] In the management server 40, the service
information management unit 41 associates the operator
information including the biological information and the
operator behavior information, the mobile object
30 information, and the operation information, thereby causing
the service information accumulation unit 42 to accumulate
them as service information. The determination logic
setting unit 43 sets and updates the determination logic
24
using the service information including the operator
behavior information. The determination unit 46 determines
an operating state of the operator 1 using the service
information including the operator behavior information.
5 For example, when the operator 1 has forgotten to perform
pointing and calling, the determination logic setting unit
43 determines that the operator 1 is not concentrating on
driving and sets a determination logic for the possibility
of overspeed or overrun. When the operator information
10 acquired by the service information management unit 41
indicates that pointing and calling by the operator 1 has
been forgotten, the determination unit 46 can increase the
determination level and determine that there is a
possibility of occurrence of overspeed, overrun, or the
15 like.
[0042] A specific example of determining the operating
state of the operator 1 in the determination unit 46 will
be described. For example, it is assumed that a body
temperature and brain waves are detected as the biological
20 information of the operator 1, a blink speed of the
operator 1 is detected as the operator behavior information
of the operator 1, and a determination logic of
“determination logic #3: when △△ seconds or longer have
elapsed from the last operation and a decrease in the blink
25 speed, a decrease in the brain function, and an increase in
the body temperature are detected, drowsiness tends to be
high so that drowsy driving may occur” is accumulated in
the determination logic accumulation unit 44. When the
blink speed, the brain waves, and the body temperature of
30 the operator 1 match the determination logic #3 in the
service information acquired by the service information
management unit 41, the determination unit 46 determines a
determination level regarding the possibility of drowsy
25
driving of the operator 1 and outputs the determination
level as a determination result to the notification unit 22.
As a result, the operator 1 can grasp the current operating
state by checking the content of the notification by the
5 notification unit 22.
[0043] A flowchart for illustrating the operation of the
driving operation management system 50a is similar to the
flowchart of the operation of the driving operation
management system 50 of the first embodiment illustrated in
10 FIGS. 4 and 6. In a hardware configuration of the driving
operation management system 50a, the operator behavior
detection unit 23 is a sensor such as a camera as described
above.
[0044] As described above, according to the present
15 embodiment, the driving operation management system 50a can
further improve the accuracy of determining the operating
state of the operator 1 by using, as the operator
information, the operator behavior information indicating
the behavior of the operator 1 that is significantly
20 related to driving together with the biological information.
The driving operation management system 50a can also point
out simple omission of checking by the operator 1 or the
like, and can cause the operator 1 to operate the train 100
more reliably.
25 [0045] Note that the driving operation management system
50a uses the biological information and the operator
behavior information as the operator information, but is
not limited to such a configuration. The driving operation
management system 50a may use only the operator behavior
30 information as the operator information.
[0046] Third Embodiment.
As the operator information, a third embodiment
further uses living information of the operator 1 obtained
26
when he is not operating the train. Differences from the
first embodiment will be described. Note that although the
description will be made using the first embodiment as an
example, the description is also applicable to the second
5 embodiment.
[0047] FIG. 10 is a block diagram illustrating an
example of a configuration of a driving operation
management system 50b according to the third embodiment.
The driving operation management system 50b is obtained by
10 replacing the terminal device 20 in the driving operation
management system 50 of the first embodiment illustrated in
FIG. 1 with a terminal device 20b. The terminal device 20b
includes an operator information accumulation unit 21b, the
notification unit 22, and a living information acquisition
15 unit 24. The living information acquisition unit 24
acquires the living information indicating a living
condition of the operator 1, and causes the operator
information accumulation unit 21b to accumulate the
acquired living information as the operator information.
20 The living information of the operator 1 is information
other than that related to the train service by the
operator 1, specifically, information such as hours of
sleep or whether or not the operator has an illness. For
example, the living information acquisition unit 24 may
25 cause the operator 1 to input information such as the hours
of sleep of the operator 1 on the previous day or whether
or not he had breakfast in a questionnaire form, or may
have a sleep hour acquisition application or the like
included in the terminal device 20b in advance and
30 automatically acquire the information. The living
information acquisition unit 24 is, for example, an input
interface such as a button or a keyboard with which the
operator 1 can input information. The operator information
27
accumulation unit 21b includes the function of the operator
information accumulation unit 21 of the first embodiment
and the function of accumulating the living information as
the operator information. The operator information
5 accumulation unit 21b outputs, as the operator information,
biological information acquired from the biosensor 10 and
the living information acquired from the living information
acquisition unit 24 to the service information management
unit 41.
10 [0048] In the management server 40, the service
information management unit 41 associates the operator
information including the biological information and the
living information, the mobile object information, and the
operation information, thereby causing the service
15 information accumulation unit 42 to accumulate them as
service information. The determination logic setting unit
43 sets and updates the determination logic using the
service information including the living information. The
determination unit 46 determines an operating state of the
20 operator 1 using the service information including the
living information. For example, in a case where the
operator 1 had short hours of sleep on the previous day,
the determination logic setting unit 43 sets a
determination logic for the possibility of overrun by the
25 operator 1. When the operator information acquired by the
service information management unit 41 indicates that the
operator 1 had short hours of sleep on the previous day,
the determination unit 46 can increase the determination
level and determine that there is a possibility of
30 occurrence of overrun.
[0049] A specific example of determining the operating
state of the operator 1 in the determination unit 46 will
be described. For example, it is assumed that the heart
28
rate and the amount of perspiration are detected as the
biological information of the operator 1, information that
the hours of sleep of the operator 1 on the previous day
are five hours is acquired as the living information of the
5 operator 1, and a determination logic of “determination
logic #4: when the hours of sleep are within six hours, the
heart rate is 80 or higher, and the amount of perspiration
is high, there is a possibility of overrun” is accumulated
in the determination logic accumulation unit 44. When the
10 information on the heart rate and amount of perspiration of
the operator 1 and the hours of sleep of the operator 1 on
the previous day in the service information acquired by the
service information management unit 41 matches the
determination logic #4, the determination unit 46
15 determines the determination level regarding the
possibility of overrun by the operator 1 and provides
notification to the operator 1 via the notification unit 22.
[0050] A flowchart for illustrating the operation of the
driving operation management system 50b is similar to the
20 flowchart of the operation of the driving operation
management system 50 of the first embodiment illustrated in
FIGS. 4 and 6. In a hardware configuration of the driving
operation management system 50b, the living information
acquisition unit 24 is the input interface such as a button
25 or a keyboard as described above.
[0051] As described above, according to the present
embodiment, the driving operation management system 50b can
further improve the accuracy of determining the operating
state of the operator 1 by using, as the operator
30 information, the living information such as information
that cannot be acquired by the biological information
acquisition unit 11 and information that does not change
with time together with the biological information.
29
[0052] Note that the driving operation management system
50b may further use the operator behavior information
described in the second embodiment. This allows the
driving operation management system 50b to further improve
5 the accuracy of determining the operating state of the
operator 1. In this case, the operator information
accumulation unit 21b outputs, as the operator information,
the biological information acquired from the biosensor 10,
the operator behavior information acquired from the
10 operator behavior detection unit 23, and the living
information acquired from the living information
acquisition unit 24 to the service information management
unit 41. In the management server 40, the service
information management unit 41 associates the operator
15 information including the biological information, the
operator behavior information, and the living information,
the mobile object information, and the operation
information, thereby causing the service information
accumulation unit 42 to accumulate them as the service
20 information.
[0053] Fourth Embodiment.
In a fourth embodiment, route information on a route
on which the train 100 travels is included in the service
information. Differences from the first embodiment will be
25 described. Note that although the description will be made
using the first embodiment as an example, the description
is also applicable to the second and third embodiments.
[0054] FIG. 11 is a block diagram illustrating an
example of a configuration of a driving operation
30 management system 50c according to the fourth embodiment.
The driving operation management system 50c is obtained by
replacing the integrated train management apparatus 30 in
the driving operation management system 50 of the first
30
embodiment illustrated in FIG. 1 with an integrated train
management apparatus 30c. The integrated train management
apparatus 30c includes the mobile object information
acquisition unit 31, the driving operation reception unit
5 32, a route information accumulation unit 33, and a route
information acquisition unit 34. The route information
accumulation unit 33 accumulates the route information that
is information on a route on which the train 100 travels.
The route information is information associated with the
10 route such as a landmark or a gradient. The landmark is,
for example, a traffic light, a railroad crossing, a sign,
or the like. The route information acquisition unit 34
acquires, from the route information accumulation unit 33,
the route information on a route on which the train 100
15 currently travels. The route information acquisition unit
34 outputs the acquired route information to the service
information management unit 41. The route information
acquisition unit 34 identifies necessary route information
by using a route name, a distance from a station, or the
20 like. The route information may also include weather
information at a travel point. The route information
acquisition unit 34 may acquire the weather information at
the travel point from an external device (not illustrated)
via a communication device (not illustrated).
25 [0055] In the management server 40, the service
information management unit 41 associates the operator
information, the mobile object information, the operation
information, and the route information, thereby causing the
service information accumulation unit 42 to accumulate them
30 as service information. That is, the service information
management unit 41 causes the service information
accumulation unit 42 to accumulate the service information
including the route information. The determination logic
31
setting unit 43 sets and updates the determination logic
using the service information including the route
information. The determination unit 46 determines an
operating state of the operator 1 using the service
5 information including the route information. For the heart
rate and the amount of perspiration of the operator 1, the
determination logic setting unit 43 changes the content of
the determination logic for overspeed depending on the
travel route of the train 100 such as between a straight
10 section and a curved section. On the basis of the route
information included in the service information acquired by
the service information management unit 41, the
determination unit 46 can determine the operating state of
the operator 1 using the determination logic that matches
15 the condition of the current travel route. The
determination unit 46 can, for example, determine the
possibility of overspeed of the train 100 using the
determination logic that matches the condition of the
current travel route.
20 [0056] A flowchart for illustrating the operation of the
driving operation management system 50c is similar to the
flowchart of the operation of the driving operation
management system 50 of the first embodiment illustrated in
FIGS. 4 and 6. In a hardware configuration of the driving
25 operation management system 50c, the route information
accumulation unit 33 is a memory. The route information
acquisition unit 34 is implemented by processing circuitry.
[0057] As described above, according to the present
embodiment, the driving operation management system 50c
30 includes the route information on the route on which the
train 100 travels in the service information, thereby being
able to set and update the determination logic using the
service information of a similar travel route, and further
32
improve the accuracy of determining the operating state of
the operator 1. Since points to be noted are different
depending on the travel route, the driving operation
management system 50c can provide information according to
5 the travel route.
[0058] The configuration illustrated in the above
embodiment merely illustrates an example of the content of
the present invention, and can thus be combined with
another known technique or partially omitted and/or
10 modified without departing from the scope of the present
invention.
