Description

  The present invention relates to a position management system and a position management method.

  At the airport, a towing tractor (hereinafter referred to as “TT car”) and a dolly are used to move luggage within the airport. The TT vehicle moves within the airport by towing a plurality of dollies carrying containers and pallets.

  The dolly arrived at the destination by being pulled by the TT car is separated from the TT car. Since the dolly itself has no power, the dolly separated from the TT car is left on the spot until it is next connected to the TT car. This makes it difficult to know where the dolly is in the airport.

  In order to manage the position of the object that moves with the moving body, a configuration using GPS (Global Positioning System) is conceivable. For example, Patent Document 1 discloses a configuration in which a GPS device is provided in a dolly and position information is periodically transmitted from the dolly to the remote control device. Further, for example, Patent Document 2 discloses a configuration in which GPS signals are received at a tag attached to a load loaded on a mobile body, and position information is transmitted to a server via a mobile communication device. .

  However, as disclosed in Patent Document 1, in the configuration in which the position information is transmitted from each dolly to the remote control device, the power consumption in each dolly increases. Therefore, it is difficult to apply to a dolly in which the capacity of the mounted battery is relatively small. Further, in the configuration disclosed in Patent Document 2, since the position information acquired with the tag is transmitted to the server via the mobile communication device, the power consumption in the tag is relatively small. However, although the position of the load when the load is moving with the moving body can be grasped, it is not possible to determine where the load is after the movement of the load with the moving body is completed.

  The present invention has been made in view of such circumstances, and aims to manage the position of an object when the movement of the object with the moving body is completed after reducing the power consumption of the object. To do.

Or four or more.

  Base unit 110 is installed in TT car 140 (moving body). Master device 110 acquires information related to dolly 150 connected to TT vehicle 140 from slave device 120 installed in dolly 150. Acquisition of information from the slave unit 120 can be performed using short-range wireless communication such as infrared communication, for example. Then, base unit 110 transmits dolly position information that is information related to the position of dolly 150 to management server 130. Transmission to the management server 130 is performed using, for example, a mobile phone line. Specifically, base unit 110 can transmit information to management server 130 via Internet 170 by communicating with mobile phone base station 160.

  The subunit | mobile_unit 120 is installed in the dolly 150 (object). The subunit | mobile_unit 120 transmits the information regarding the dolly 150 to the main | base station 110 currently installed in the TT car 140. FIG. The subunit | mobile_unit 120 can transmit the dolly information (object information) which is the information regarding the dolly 150 regularly, for example, while the dolly 150 is moving. The dolly information includes, for example, a dolly ID that is an identifier of the dolly, position information that indicates the current position of the dolly 150, mounted object information that indicates a state of the container 180 (mounted object) mounted on the dolly 150, and the like.

  Management server 130 stores dolly position information received from base unit 110 installed in TT car 140. The management server 130 grasps the position and state of the dolly 150 based on the dolly position information.

  FIG. 2 is a diagram showing an example of the configuration of base unit 110. Master device 110 includes power supply unit 200, position sensor 210, movement sensor 220, processor 230, memory 240, short-range communication interface 250, and wireless communication interface 260.

  The wireless communication interface 260 is an interface for performing wireless communication with the base station 160. For example, a mobile phone line or a wireless LAN (Local Area Network) can be used for communication through the wireless communication interface 260. The power consumption of the wireless communication interface 260 is generally larger than the power consumption of the short-range communication interface 250.

  FIG. 3 is a diagram illustrating an example of the configuration of the slave unit 120. The subunit | mobile_unit 120 is provided with the power supply part 300, the position sensor 310, the movement sensor 320, the mounted object sensor 330, the processor 340, the memory 350, and the near field communication interface 360.

  The power supply unit 300 supplies power to each element of the child device 120. The power supply unit 300 acquires power from, for example, a rechargeable battery. The power supply unit 300 may charge the battery using solar power generation or power generation associated with the running of the dolly 150. The power supply unit 300 need not always supply power to all elements of the slave unit 120. For example, the slave unit 120 may supply electric power only to the movement sensor 320 when the dolly 150 is stopped, and may supply electric power to other elements when the movement of the dolly 150 is detected by the movement sensor 320.

  The position sensor 310 is a sensor that can output position information indicating the current position. The position sensor 310 is, for example, a GPS receiver. Note that when the parent device 110 includes the position sensor 210, the child device 120 does not need to include the position sensor 310.

  The movement sensor 320 is a sensor that can detect a movement state. The movement sensor 320 is, for example, an acceleration sensor or an angular velocity sensor. In addition, the subunit | mobile_unit 120 does not need to be provided with the movement sensor 320. FIG.

  The load sensor 330 is a sensor that can detect the state of a load mounted on the dolly 150. The on-board sensor 330 is, for example, an infrared sensor, an RFID reader, a weight sensor, or the like. The mounted object sensor 330 can detect the presence or absence of a mounted object and the ID of the mounted object, for example. In addition, the subunit | mobile_unit 120 does not need to be provided with the mounted object sensor 330. FIG.

  The processor 340 can implement various functions by executing a program stored in the memory 350. Functions realized in the slave unit 120 will be described later.

  The memory 350 is a storage device for storing programs and data. The memory 350 includes, for example, a nonvolatile memory and a volatile memory.

  The short-range communication interface 360 is an interface for performing short-range wireless communication with the parent device 110. For communication using the short-range communication interface 360, for example, infrared rays, Bluetooth (registered trademark), RFID (Radio Frequency Identifier), or the like can be used. Note that the short-range communication interface 360 does not have to actively transmit information. For example, the short-range communication interface 360 may be a passive IC (Integrated Circuit) tag.

  FIG. 4 is a diagram illustrating an example of a functional unit realized in the parent device 110. Base device 110 includes TT car ID storage unit 400, dolly information acquisition unit 410, dolly information storage unit 420, movement determination unit 430, and position information transmission unit 440. These units can be realized, for example, by using a storage area of the memory 240 or by the processor 230 executing a program stored in the memory 240.

  The TT car ID storage unit 400 stores a TT car ID that is an identifier of the TT car 140. The TT vehicle ID stored in the TT vehicle ID storage unit 400 can be rewritten.

  The dolly information acquisition unit 410 (object information acquisition unit) acquires the dolly information from the child device 120 installed in the dolly 150 and stores it in the dolly information storage unit 420. For example, the dolly information acquisition unit 410 may receive dolly information periodically transmitted from the child device 120 or may actively acquire the dolly information from the child device 120. It should be noted that the dolly information acquisition unit 410 stores only the dolly information of the dolly 150 identified as being connected to the TT car 140 in the dolly information storage unit 420 among the acquired dolly information. The dolly information includes, for example, a dolly ID, position information, movement information, and load information. The position information is information indicating the current position of the dolly 150. The position information includes time information. The movement information is information indicating the movement state (movement direction, movement speed, movement acceleration, etc.) of the dolly 150. The mounted object information is information related to a mounted object mounted on the dolly 150 (presence / absence of a mounted object, ID of the mounted object, etc.). The dolly information may include battery information indicating the state of the battery. Information other than the dolly ID in the dolly information is not essential.

  The movement determination unit 430 determines the movement state of the dolly 150. Specifically, movement determination unit 430 identifies dolly 150 connected to TT vehicle 140 in which base unit 110 is installed. For example, the movement determination unit 430 can specify that the dolly 150 that acquired the dolly information is the connected dolly 150.

  By the way, since there are a large number of dollies 150 in the airport, there is a possibility that the base unit 110 of the TT car 140 may acquire dolly information of the dollies 150 that are not connected. Therefore, for example, the movement determination unit 430 can identify the dolly 150 connected to the TT vehicle 140 based on the detection result of the movement sensor 320 of the parent device 110 and the movement information acquired from the child device 120. .

  FIG. 5 is a diagram showing an example of how the dolly 150 connected to the TT car 140 is specified. In the example shown in FIG. 5, dollies 150A1 and 150A2 are connected to the TT vehicle 140A, and dollies 150B1 and 150B2 are connected to the TT vehicle 140B. Dolly 150B1 and 150B2 are connected to TT vehicle 140B, but are also close to TT vehicle 140A. Therefore, base unit 110 of TT car 140A may acquire dolly information of dollies 150B1 and 150B2 in addition to the dolly information of dollies 150A1 and 150A2. Therefore, even if base unit 110 of TT car 140A identifies dollies 150A1 and 150A2 connected to TT car 140A based on movement information (movement direction, movement speed, movement acceleration, etc.) included in the dolly information. Good. Specifically, for example, base unit 110 of TT car 140 is a dolly in which dollies 150A1 and 150A2 moving at substantially the same speed in the same direction as TT car 140A are connected to TT car 140A. Can be specified. Similarly, the master unit 110 of the TT car 140B also identifies the dollies 150B1 and 150B2 that are moving at substantially the same speed in the same direction as the TT car 140B as being connected to the TT car 140B. Can do.

  Note that the method for identifying the dolly 150 that is connected to the TT vehicle 140 and moves is not limited to this. For example, as described above, the movement determination unit 430 may specify that all the dollies 150 that have acquired the dolly information are connected dollies 150. In this case, there is a high possibility that the dolly information of the dolly 150 that is not actually connected cannot be acquired midway. The movement determination unit 430 can determine that the dolly 150 is not connected when the dolly information of some of the dollies 150 cannot be acquired from the middle. When specifying the connected dolly 150, the signal strength of the dolly information (the signal strength (RSSI) of the radio wave received by the parent device 110 from the child device 120; the same shall apply hereinafter) may be used. Moreover, the movement determination part 430 may show the information of all the dolly 150 which acquired dolly information to the pilot of the TT car 140, and may identify the connected dolly 150 by a pilot's input.

  In addition, the movement determination unit 430 can determine that the dolly 150 is disconnected after the dolly 150 is connected. For example, the movement determination unit 430 may determine that the dolly 150 has been disconnected when the dolly information cannot be acquired from the connected dolly 150 for a predetermined time or longer after the connected dolly 150 is identified. In addition, the determination method of connection cancellation | release is not restricted to this. For example, the movement determination unit 430 may determine that the connection of the dolly 150 is released when the position of the TT vehicle 140 and the position of the dolly 150 are separated by a predetermined distance or more. Further, for example, the movement determination unit 430 may determine that the connection of the dolly 150 has been released when the movement state of the TT vehicle 140 and the movement state of the dolly 150 change from substantially the same state to a different state.

  Furthermore, the movement determination unit 430 may determine the arrangement order of the connected dollies 150 based on the dolly information acquired from the child device 120. For example, the movement determination unit 430 can determine the arrangement order of the dollies 150 based on the position information included in the dollie information. In addition, the movement determination unit 430 can determine the arrangement order of the dollies 150 based on the signal strength of the dollie information and the communication time between the parent device 110 and the child device 120.

  The position information transmission unit 440 is based on the position information acquired by the position sensor 210 of the parent device 110 or the position sensor 310 of the child device 120, the dolly information acquired from the child device 120, and the determination result of the movement determination unit 430. Then, the dolly position information (object position information) indicating the position of the connected dolly 150 is transmitted to the management server 130. The position information transmission unit 440 sends at least the dolly position information indicating the position of the dolly 150 to the management server 130 when the movement of the dolly 150 associated with the TT car 140 is completed (that is, when the connection of the dolly 150 is released). Send. Further, the position information transmission unit 440 may transmit the dolly position information indicating the position of the dolly 150 to the management server 130 when the dolly 150 is being connected to the TT car 140. The dolly position information includes, for example, a TT car ID, a dolly ID, position information, connection information indicating a connection state (connected or disconnected), information indicating an arrangement order, and mounted object information. Information other than the dolly ID and the position information in the dolly position information is not essential.

  FIG. 6 is a diagram illustrating an example of a functional unit realized in the slave unit 120. The subunit | mobile_unit 120 is provided with the dolly ID memory | storage part 600 and the dolly information transmission part 610. FIG. These units can be realized, for example, by using a storage area of the memory 350 or by the processor 340 executing a program stored in the memory 350.

  The dolly ID storage unit 600 stores a dolly ID that is an identifier of the dolly 150. The dolly ID stored in the dolly ID storage unit 600 can be rewritten.

  Dolly information transmission unit 610 (object information transmission unit) transmits dolly information to base unit 110. For example, the dolly information transmission unit 610 may periodically transmit the dolly information. Further, the dolly information transmission unit 610 may transmit the dolly information in response to a request from the parent device 110. In the slave unit 120, power is supplied to the dolly information transmission unit 610 when the dolly 150 is moving under the control of the power supply unit 300, and power is supplied to the dolly information transmission unit 610 when the dolly 150 is stopped. Can be stopped.

  FIG. 7 is a diagram illustrating an example of a functional unit realized in the management server 130. The management server 130 includes a position information receiving unit 700, a position information storage unit 710, a search reception unit 720, a dolly information output unit 730, an operation information storage unit 740, a reservation reception unit 750, and a reservation information storage unit 760. The management server 130 is a computer including a memory and a processor, and each unit illustrated in FIG. 7 can be realized by, for example, using a storage area of the memory or executing a program stored in the memory by the processor. it can.

  Position information receiving section 700 receives dolly position information from base unit 110 and stores it in position information storage section 710.

  The search reception unit 720 receives a search request for confirming the position of the dolly 150 from the user. The search request includes, for example, a dolly ID. Further, when not only the disconnected dolly 150 but also the dolly position information of the connected dolly 150 is stored in the position information storage unit 710, a connection state (connected or disconnected) is specified in the search request. Information may be included.

  The dolly information output unit 730 outputs information indicating the position and connection state of the dolly 150 based on the dolly position information stored in the position information storage unit 710. Any format can be adopted for the output of information. For example, the information output format may be display on a display, data transmission via a network, printing on paper, or the like. The dolly information output unit 730 can display the position of each dolly 150 on the screen based on the dolly position information, for example. When the dolly position information of the connected dolly 150 is also stored in the position information storage unit 710, the dolly information output unit 730 displays the position of the dolly 150 on the airport map so that the connection state can be identified. be able to. Further, the dolly information output unit 730 may output the state of the mounted object, the state of the battery of the slave unit 120, and the like.

  The flight information storage unit 740 stores flight schedule information (such as flight name, date, departure / arrival airport, terminal, gate, equipment used, etc.).

  The reservation receiving unit 750 receives a reservation request for reserving use of the dolly 150 from the user. For example, the reservation receiving unit 750 can receive a reservation for use of the dolly 150 that has been disconnected (that is, not used) based on the output result of the dolly information output unit 730. Moreover, the reservation reception part 750 can provide the operation schedule information memorize | stored in the operation information memory | storage part 740 as a reference information for making a reservation of the dolly 150 to a user. For example, the user can reserve the dolly 150 to be used in a specific flight with reference to the information output from the dolly information output unit 730 and the operation schedule information. The reservation receiving unit 750 stores the confirmed reservation information in the reservation information storage unit 760.

  FIG. 8 is a flowchart illustrating an example of processing in the location management system 100. FIG. 8 shows processing in the parent device 110 and the child device 120.

  First, the processing of the slave unit 120 will be described. In the slave unit 120, when the movement of the dolly 150 is detected based on the detection result of the movement sensor 320 (S801), the power supply unit 300 starts power supply to each element of the slave unit 120 (S802). The position sensor 310 acquires the current position (S803), and the movement sensor 320 detects the movement state (S804). The dolly information transmission unit 610 transmits the dolly information to the parent device 110 (S805). Based on the detection result of the movement sensor 320, while the dolly 150 is moving (S806: moving), the current position is acquired (S803), the moving state is detected (S804), and the dolly information is transmitted (S805). Is done.

  When the movement sensor 320 detects the movement stop of the dolly 150 (S806: movement stop), the position sensor 310 acquires the current position (S807), and the dolly information transmission unit 610 transmits the dolly information to the base unit 110 (S808). . And the power supply part 300 stops the electric power supply to each element other than the movement sensor 320 (S809). By acquiring the current position and transmitting the dolly information after the movement stop is detected, accurate position information of the dolly 150 when the movement of the dolly 150 associated with the TT car 140 is completed can be transmitted to the base unit 110. it can. Since the dolly position information is repeatedly transmitted during the movement, the dolly information may not be transmitted after the movement stop is detected.

  Next, processing of base unit 110 will be described. In base unit 110, position sensor 210 acquires the current position (S811), and movement sensor 220 detects the movement state (S812). When the dolly information acquisition unit 410 receives the dolly information from the child device 120 (S813), the movement determination unit 430 determines the connection of the dolly 150 (S814). While the dolly 150 is not connected (S814: not connected), acquisition of the current position (S811), detection of the moving state (S812), and reception of dolly information (S813) are repeatedly executed.

  When the connection of the dolly 150 is detected (S814: connection), the position sensor 210 acquires the current position (S815), and the movement sensor 220 detects the movement state (S816). Further, the dolly information acquisition unit 410 receives the dolly information from the slave unit 120 of the connected dolly 150 (S817). Then, the position information transmission unit 440 transmits the dolly position information of the connected dolly 150 to the management server 130 (S818). While the dolly 150 is being connected (S819: being connected), acquisition of the current position (S815), detection of the moving state (S816), reception of dolly information (S817), and transmission of dolly position information (S818) are repeatedly executed. .

  When the movement determination unit 430 detects the disconnection of the dolly 150 (S819: disconnection), the dolly information acquisition unit 410 receives the dolly information when the dolly 150 stops moving (S820). Then, the position information transmission unit 440 transmits the dolly position information of the disconnected dolly 150 to the management server 130 (S821). Thereafter, returning to the top of the process, until the next dolly 150 is connected, acquisition of the current position (S811), detection of the moving state (S812), and reception of dolly information (S813) are repeatedly executed.

  The present embodiment has been described above. In the present embodiment, the slave unit 120 installed in each dolly 150 transmits the dolly information to the master unit 110 installed in the TT car 140 by communication means with relatively small power consumption such as short-range wireless communication. . Then, base unit 110 transmits, to management server 130, dolly position information indicating the position of dolly 150 when the connection is released from TT car 140 via a communication network such as a mobile phone line. As a result, it is possible to manage the position of the dolly 150 when the movement of the dolly 150 accompanying the TT car 140 is completed while reducing the power consumption in the dolly 150.

  As described in the present embodiment, dolly position information indicating the position of the dolly 150 connected to the TT vehicle 140 may be transmitted to the management server 130. Thereby, it is possible to grasp the position of the dolly 150 that is connected to the TT car 140 and is moving.

  In the present embodiment, the dolly position information transmitted to the management server 130 can include the load information related to the load mounted on the dolly 150. Thereby, the position of a load (for example, container) can also be grasped.

  In the present embodiment, the movement of the dolly 150 is detected. When the dolly 150 starts moving, power supply to the dolly information transmission unit 610 is started, and when the movement of the dolly 150 ends, the dolly information transmission unit 610 is supplied. The power supply can be stopped. Thereby, the power consumption in the dolly 150 can be further reduced.

  Moreover, in this embodiment, based on the movement information (movement direction, movement speed, etc.) of the dolly 150, it is possible to identify the dolly 150 that moves with the TT vehicle 140 among the plurality of dolly 150. Then, base unit 110 of TT car 140 can transmit the dolly position information of the identified dolly 150 (connected dolly 150) to management server 130. Thereby, the determination accuracy of the dolly 150 connected to the TT car 140 can be increased in an environment where there is a possibility that a large number of dollies may be close to each other as in an airport.

  Note that this embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  For example, in the present embodiment, the parent device 110 installed in the TT vehicle 140 determines the movement state (connected / disconnected) of the dolly 150 associated with the TT vehicle 140, but the management server 130 determines the dolly 150. The movement state may be determined. In this case, base unit 110 installed in TT vehicle 140 may transmit dolly position information indicating the position of dolly 150 to management server 130 regardless of the movement state of dolly 150. The management server 130 can determine the movement state (connected / unconnected) of the dolly 150 based on the history of the dolly position information received from the parent device 110. For example, when the position information of the dolly 150 changes, the management server 130 can determine that the dolly 150 is connected to the TT car 140 and is moving. Further, when the state in which the position information of the dolly 150 does not change continues for a predetermined time, it can be determined that the movement of the dolly 150 accompanying the TT car 140 is completed (disconnected).

  In the present embodiment, an example of managing the position of the dolly 150 has been shown. However, in the present invention, the position management target is not limited to the dolly 150, and may be applied to any object that moves with a moving object. it can. For example, the present invention can be applied to position management of blood or organ containers (objects) that move with an emergency transport vehicle (moving body).
