[0025]
　Figure 8 is a diagram showing a first operation example of the forklift.
　Figure 8 shows a state forklift 10, which insert the forks of the bottom forklift 10 of the container 20 which are placed on the site, such as a container yard. This example is the situation seen in the second time the first timing or forklift 10, the forklift 10 starts carrying lifts the containers 20 from the ground is disposed at a predetermined position of the site by moving the container 20.
　Luggage management unit 72 if the determined first timing, first, baggage management unit 72 when in a state of not carrying container 20 does not receive the cargo ID in the first antenna 11 and second antenna 12 determines (1-a). Then when the fork is inserted under the container 20, baggage management unit 72 if the luggage tag 21 is attached to the container 20 that receives the package ID and the first forklift ID with only the first antenna 11 determining (1-b1). If the luggage tag 21 is not attached to the container 20, baggage management unit 72 determines that it has received the first forklift ID with only the first antenna 11 (1-b2). If the condition of such time series occurs, baggage management unit 72 determines that the first timing has occurred. Note the second antenna 12 is mounted on the forklift 10 so that the radio wave directivity that can not detect the cargo ID and first forklift ID in the context of the 1-b.
[0026]
　Luggage management unit 72 in the case of determining a second timing when the driver lifts the container 20 by operating the forklift 10, the first antenna 11 if baggage tag 21 is attached to the container 20 and the second antenna 12 as you receive the package ID and the first forklift ID in both the cargo management unit 72 determines (2-a1). Also when the driver lifts the container 20 by operating the forklift 10 receives the first forklift ID in both the first antenna 11 unless luggage tag 21 is attached to the container 20 and the second antenna 12 It is the package management unit 72 determines (2-a2). Luggage management unit 72, when the forklift 10 is put containers 20 on the destination receives the package ID and the first forklift ID only the first antenna 11 if baggage tag 21 is attached to the container 20 It determines that there (2-b1).

The baggage managing unit 72, when the forklift 10 is back, the first antenna 11 and the second both the antenna 12 is determined not to have received the parcel ID or the first forklift ID in (2-c). If the condition of such time series occurs, baggage management unit 72 determines that the second timing has occurred. Note the second antenna 12, in the context of 2-b1 or 2-b2 is attached to the forklift 10 so that the radio wave directivity that can not detect the package ID.
[0027]
　Figure 9 is a diagram showing a second operation example of the forklift.
　Forklift 10 in FIG. 9, showing a state in which in a state where the container 20 is disposed in freight cars for stacking containers 20 are insert the fork of the forklift 10 in the bottom of the container 20. This example is seen in the fourth timing tertiary timing or the forklift 10, to begin carrying lift the container 20 forklift 10 from wagon to another position tries to load by moving the freight containers 20 from another position in the wagons is a situation that is.
　Luggage management unit 72 when determining the third timing, first of antenna 11 and the second antenna 12 Failure to detect cargo ID and first forklift ID in both the cargo management unit 72 determines (3-a ). Then cargo management unit 72 determines that when the luggage tag 21 is attached to container 20 has detected the package ID and position ID and the first forklift ID in the first antenna 11 (3-b1) . Or baggage managing unit 72, a container when the baggage tag 21 is not attached to the 20, position ID and the determining (3-b2) was detected and the first forklift ID in the first antenna 11. If the condition of such time series occurs, baggage management unit 72 determines that the third timing occurs. Note the second antenna 12 is mounted on the forklift 10 so that the radio wave directivity that can not detect the cargo ID and position ID and first forklift ID in the context of the 3-b1 and 3-b2.
[0028]
　Luggage management unit 72 when determining the fourth timing, if baggage tag 21 is attached to the container 20, baggage ID is like during traveling of the forklift 10 in both the first antenna 11 and second antenna 12 When package management unit 72 and detects the first forklift ID determines (4-a1). Or luggage management unit 72 when determining the fourth timing, unless the baggage tag 21 is attached to the container 20, is such as during traveling of the forklift 10 second in both the first antenna 11 and second antenna 12 luggage management unit 72 and detects an forklift ID determines (4-a2). Then when placing the container 20 in wagons, determined if baggage tag 21 is attached to the container 20, baggage managing unit 72 can not detect the package ID and the first forklift ID at the second antenna 12 to (4-b1). Or container 20 when placed in wagons, unless luggage tag 21 is attached to the container 20, baggage management unit 72 determines that it can not detect the first forklift ID at the second antenna 12 (4-b2 ). Then cargo management unit 72 if the luggage tag 21 is attached to the container 20, it is judged that it has detected the position ID and the first forklift ID and package ID in the first antenna 11 (4-c1). Or if cargo management unit 72 has not luggage tag 21 is attached to the container 20, it is judged that it has detected the position ID and the first forklift ID in the first antenna 11 (4-c2). If the condition of such time series occurs, baggage management unit 72 determines that the fourth timing is generated. Note the second antenna 12, 4-c1 and luggage ID in the context of the 4-c2, position ID, and is attached, such as the forklift 10 so as to be directed in the radio which can not detect the first forklift ID.
[0029]
　Figure 10 is a diagram showing a third operation example of the forklift.
　10 In the forklift 10, showing a state where the bottom has insert the fork of the forklift 10 of the container 20 disposed in the upper in a state where the container 20 is arranged to overlap. This example forklift 10 is a fifth timing or forklift 10, to begin carrying lift the container 20 disposed in the upper to the other position is to complete the deployment of the container 20 has been moved from another position on the container 20 is a situation that is seen in the sixth timing to be.
[0030]
　If baggage managing unit 72 to determine the fifth timing, first because the forklift 10 is not carrying a container 20, are able to both detect cargo ID and first forklift ID is the first antenna 11 and second antenna 12 and without cargo management unit 72 determines (5-a). Then for inserting the fork of the forklift 10 in the bottom of the upper container 20, luggage both cargo management unit 72 when the baggage tag 21 is attached to container 20 from the first antenna 11 and second antenna 12 ID and determines that it has detected a first forklift ID (5-b1). Or for inserting the fork of the forklift 10 in the bottom of the upper container 20, the container 20 loads management unit 72 when the luggage tag 21 is not attached to the first in both the first antenna 11 and second antenna 12 It determines that it has detected a forklift ID (5-b2). If the condition of such time series occurs, baggage management unit 72 determines that the fifth timing occurs.
　If baggage managing unit 72 to determine a sixth timing, if baggage tag 21 is attached to the container 20, and luggage ID on both the first antenna 11 during running of the forklift 10 and the second antenna 12 second luggage management unit 72 has been detected and one forklift ID determines (6-a1). Unless luggage tag 21 is attached to the container 20, baggage managing unit 72 during travel to the first antenna 11 and detects the first forklift ID in both the second antenna 12 of the forklift 10 determines (6- a2). The package managing unit 72 determines that the time has detected the package ID and the first forklift ID in both the first antenna 11 and the second antenna 12 is longer than a predetermined time (6-b). The package managing unit 72 judges that no longer detect the cargo ID and first forklift ID in both the first antenna 11 and second antenna 12. If the condition of such time series occurs, baggage management unit 72 determines that the sixth timing occurs.
[0031]
　Incidentally determination method of each timing shown in FIGS. 8 to 10 described above is only an example, the reception time and the time of the first antenna 11 and the second package ID received by the antenna 12 and the arrangement position ID and the first forklift ID luggage management unit according to the reception conditions in the sequence 72 may be configured to determine the respective timing and other timings.
[0032]
　Figure 11 is a first diagram showing a series of operations of the forklift.
　Then forklift explaining an example of the case of disposing the containers 20 are placed on the site, such as a container yard to another position on site. In this case the position where the container 20 is placed in the premises of the container yard is carried origin. The other position is a carry-out destination. Also described using the example of a case where unattached luggage tags to the container 20.
　Driver inserting the fork of the forklift 10 in the bottom of the container 20 by operating the forklift 10 (step S1). Thus the radio signals that originated in the first antenna 11 is reflected by the container 20. The first tag 15 transmits the first forklift ID based on the received reflected signals of the outgoing radio signals from the first antenna 11. The first antenna 11 receives a first forklift ID. Luggage management unit 72 determines that it has detected the first forklift ID in a first antenna 11, detects that it is the first time. Luggage management unit 72 acquires from the position detecting unit 74 the current position of the forklift 10 at the time of obtaining the first forklift ID. Luggage management section 72 information indicating that the package tag 21 is not attached to the primary recording and the current position in the storage unit 77. The package managing unit 72 information indicating that the package tag 21 is not attached, and outputs the current position to the other device cooperation unit 76. It may inform the information and current position and the first forklift ID indicating that not been other devices linkage unit 76 attached luggage tag 21 to the host system. This notification may be to include the information indicating the first timing. Such host system by treatment, which forklifts, when, at any position, it is possible to manage whether to any luggage, what was. Also it is possible to detect whether a container 20 unattached luggage tag 21 is present where the host system.
[0033]
　Driver moves the container 20 by operating the forklift 10 at other locations on site. In this case the driver to secure a visual field by lifting the forks of the forklift 10 (step S2). Then each the first antenna 11 and the second antenna 12 receives a first forklift ID. After the transition to this state from the first timing, it determines that transportation state determination unit 73 is being transported. When the forklift 10 arrives at the arrangement position of the predetermined unloading location on-site, to place the container 20 in position. In this case the second antenna 12 can not be detected the first forklift ID. Luggage management unit 72 detects that the second timing. Luggage management unit 72 acquires the current position when it detects that the second timing from the position detection unit 74. Luggage management unit 72 when the forklift 10 is back determines that no longer able to detect the first forklift ID in the first antenna 11 (step S3). Luggage management unit 72 outputs a first forklift ID that is no longer detected by the first antenna 11 and second antenna 12, the present position to another device cooperation unit 76. Other devices linkage unit 76 may inform the fact has been detected first forklift ID and the current position and the second timing to the host system. Such host system by treatment, which forklifts, when, at any position, it is possible to manage whether to any luggage, what was. The host system is able to detect whether a container 20 unattached luggage tag 21 where present.
[0034]
　Figure 12 is a second view of the series of operations of the forklift.
　Then the container 20 forklift 10 is placed on one of the wagons 41, an example of a case of arranging the other wagons 42. In this case, it is one of the wagons 41 carrying sources. In addition, which is the other wagons 42 carry-out destination. Note will be described with reference to examples in the case where the baggage tag not attached to the container 20.
　Driver inserting the fork of the forklift 10 in the bottom of the container 20 stacked on the wagons 41 by operating the forklift 10 (step S121). Thus the radio signals that originated in the first antenna 11 is reflected by the container 20. The first tag 15 receives the reflected signal outgoing radio signals from the first antenna 11, transmits the first forklift ID based on the received reflected signal. The first antenna 11 receives a first forklift ID. The first antenna 11 receives the originated placement location ID from the arrangement position tag 31. Luggage management unit 72 determines that it has detected the position ID with the first forklift ID in a first antenna 11, detects that a third timing (FIG. 9). Note the tag data check unit 78 may determine whether the position ID indicates wagons. For example, when the forklift 10 is unloading cargo from pre-specified wagons, tag data checking unit 78 determines whether position ID is or wagons, if not wagons may be determined that a warning is displayed . First antenna 11 if the container 20 to the freight car 41 were arranged continuous plurality is there is a possibility of receiving a package ID from baggage tag 21 attached to the other container 20. If baggage managing unit 72 detects a cargo ID of the container 20, to determine whether the received strength high signal to the same extent as the first forklift ID, if the signal strength to the same extent as the first forklift ID is not high signal it may be discarded. Further, at this time, when a plurality of positions tags 31 wagons is attached, baggage managing unit 72 is likely to determine that it has received the plurality of positions ID. In that case package management unit 72 determines whether it has received the position ID by a signal of the signal strength and comparable signal strength of a signal received first forklift ID. If it is received position ID is a signal of the signal strength and comparable signal strength of the first forklift ID, the position and location of baggage unattached luggage tag 21 are almost identical. Therefore, luggage management unit 72
[0035]
　Luggage management unit 72 acquires from the position detecting unit 74 the current position of the forklift 10 at the time of the acquisition and placement position ID with the first forklift ID. Luggage management unit 72 first forklift ID, position ID, and the primary recording in the storage unit 77 the current position. The luggage management unit 72 first forklift ID, position ID, and outputs the current position to the other device cooperation unit 76. Other devices linkage unit 76 first forklift ID, position ID, may inform the current position to the host system. This notification may be to include the information indicating that the third timing. Such forklift by treatment when, at any position, for any load, what you are doing can be managed by the host system. The host system is able to detect whether a container 20 unattached luggage tag 21 where present.
[0036]
　Driver moves the container 20 to the other wagons 42 by operating the forklift 10. In this case the driver to secure a visual field by lifting the forks of the forklift 10 (step S122). Then the first antenna 11 and the second antenna 12 receives a first forklift ID respectively. After the transition to this state from the third timing, it determines that transportation state determination unit 73 is being transported. When the driver arrives at the other wagon 42, to place the container 20 in the freight car 42. In this case the second antenna 12 can not be detected the first forklift ID. The first antenna 11 receives the position ID of the position tags 31 attached to freight cars 42 with the first forklift ID. This package management unit 72 by detects that a fourth timing. Incidentally, at this time, when a plurality of positions tags 31 wagons is attached, baggage managing unit 72 is likely to determine that it has received the plurality of positions ID. In that case package management unit 72 determines whether it has received the position ID by a signal of the signal strength and comparable signal strength of a signal received first forklift ID. If it is received position ID by a signal of the signal strength and comparable signal strength of the first truck ID, the position of the container 20 unattached luggage tag 21 and the arrangement position are almost identical. Accordingly, baggage managing unit 72 obtains the position ID received by the signal strength about the same signal strength of the first forklift ID.
[0037]
　Luggage management unit 72 acquires the current position when it detects that the fourth timing from the position detection unit 74. Luggage management unit 72 when the forklift 10 is back can not be detected with the first forklift ID and position ID with the first antenna 11 (step S123). Luggage management unit 72 outputs the arrangement ID and their first forklift ID to another device cooperation unit 76. Other devices linkage unit 76 first forklift ID, position ID, current position, the forklift ID, may inform the host system the detection of the fourth timing. Such host system by treatment, which forklifts, when, at any position, it is possible to manage whether to any luggage, what was. The host system is able to detect whether a container 20 unattached luggage tag 21 where present.
[0038]
　Figure 13 is a diagram illustrating a processing flow of cargo management apparatus 1.
　Luggage management unit 72 in the cargo management device 1 judges ID luggage ID received in the first antenna 11, the arrangement position ID, first forklift ID, the on which of one or more of the second Forklift ID ( step S131). Then transportation state determination unit 73 determines transportation state of the forklift (step S132). Luggage management unit 72 determines the current timing (such the first to sixth timing) based on the transportation state to detect, also received ID to identify the information of those time series are recorded ( step S133). The tag data checking unit 78 checks the baggage ID or position ID received (step S134). If the data system of the tag data check unit 78 package ID and position ID that they check does not match the system stored in the storage unit 77 may output such as a monitor warning information. Luggage management unit 72 if the current timing is a predetermined timing, determines to transmit the information to the host system (step S135). Luggage management unit 72 obtains the current position from the position detection section 74 (step S136). Luggage management unit 72 transmits package ID to the host system, position ID, first forklift ID, information of a second truck ID, current position and timing (step S137).
[0039]
　Luggage management device 1, in advance from such higher-level system, may be stored by receiving the work schedule list.
