Description

  The present invention relates to a management system, a management method, a program, a management device, and a vehicle mounting machine for managing a transport vehicle in a distribution base where a plurality of loading and unloading positions are provided.

  The logistics network is composed of logistics routes and logistics bases. The logistics route connects the logistics bases. Luggage is transported from the distribution base to another distribution base on the physical distribution route by a transportation means such as a transport vehicle. Among distribution bases, distribution centers / distribution centers maintained and operated by companies are also called “distribution centers”.

  A large number of transport vehicles that deliver merchandise come and go in the distribution center, where luggage stock storage, sorting, delivery, distribution processing, and the like are performed. The distribution center is provided with a plurality of unloading spaces, and a transport vehicle is parked in each unloading space, and loads are loaded and unloaded.

  Since there are a lot of different types and quantities of goods that are picked up at distribution centers, there is a constant demand for efficient handling of goods. Therefore, in a distribution center, it is common that a guide is arranged and a transport vehicle such as a truck is guided to a predetermined handling position by the guide.

S11). When the truck 1 passes through the entrance gate 13 and enters the distribution center 200, the radio wave of the beacon signal from the wireless communication unit 21 of the management device 20 is supplemented. Then, the controller 65 of the vehicle-mounted device 40 establishes a wireless communication channel with the management device 20 via the wireless LAN 30. Thereafter, transmission / reception between the management device 20 and the vehicle-mounted device 40 is performed via the wireless communication units 21 and 64 and the wireless LAN 30.

  After establishing the wireless communication channel, the controller 65 transmits a guidance request including identification information such as the number and ID of the track 1 stored in the storage unit 63 and information such as the load on the track 1 to the management device 20. (Step S13). Hereinafter, the identification information of the truck 1 and the information on the load of the truck 1 are also referred to as unique information of the truck 1.

  On the other hand, the controller 25 of the management apparatus 20 is waiting to receive unique information from the track 1 (step S12). When the controller 25 receives the specific information of the truck 1, the controller 25 refers to the storage unit 24, and determines the unloading parking area 12 where the truck 1 should park and load / unload luggage based on the specific information (step). S14).

  For example, when the load loaded on the truck 1 is the load A, and the load A is loaded / unloaded only in a specific load handling parking area 12, the specific load handling parking area 12 1 is determined as an area to be parked. That is, according to the present embodiment, in step S14, the controller 25 functions as a determination unit.

  Subsequently, the controller 25 refers to the usage status table 26 of the storage unit 24 and checks whether or not the determined handling parking area 12 is in use. Here, if the cargo handling parking area 12 is empty, that is, if the usage status of the cargo handling parking area 12 determined in the usage status table 26 of the storage unit 24 is 0, the controller 25 stores the storage unit 24. The usage status is updated by switching the usage status of the unloading parking area 12 in the usage status table from empty (0) to reserved (1) (step S16).

  Moreover, the controller 25 produces | generates the guidance information to the cargo handling parking area 12 determined in said step S14 with respect to the vehicle mounting machine 40 which transmitted the guidance request | requirement (step S18). This guidance information includes the determined area number of the cargo handling parking area 12.

  On the other hand, if the usage status of the cargo handling parking area 12 determined in the usage status table 26 of the storage unit 24 is reserved for use (1) or in use (2), the cargo handling parking area 12 is another truck. 1, the controller 25 registers the ID of the truck 1 on which the vehicle-mounted device 40 that transmitted the guidance request is mounted in the queue 27 of the cargo handling parking area 12 (step S16). Moreover, the controller 25 produces | generates the guidance information to the turn waiting area 14 with respect to the vehicle mounting machine 40 which transmitted the guidance request | requirement (step S18).

  After execution of step S18, the controller 25 of the management device 20 transmits guidance information for guiding the truck 1 to the vehicle-mounted device 40 that has transmitted the guidance request (step S20). As described above, when the cargo handling parking area 12 is vacant, the guidance information includes the area number and position information of the cargo handling parking area 12. On the other hand, when the cargo handling parking area 12 is not vacant and the turn is waiting, information including an instruction to wait in the turn waiting area 14 is included.

  The controller 65 of the vehicle-mounted device 40 is waiting to receive guidance information (step S21). When receiving the guidance information, the controller 65 determines whether or not the received guidance information is guidance information to the turn waiting area 14 (step S23).

  Here, it is assumed that it was not waiting for a turn. If it is not waiting for a turn (No in step S23), the controller 65 of the vehicle-mounted device 40 controls the OSD unit 62 to monitor the position, direction, area number, etc. of the cargo handling parking area 12 included in the guidance information 51. (Step S25). The driver moves the truck 1 toward the displayed handling parking area 12.

  Here, the controller 65 of the vehicle-mounted device 40 is waiting for mark recognition in the image recognition unit 61 (step S27). When the truck 1 enters the handling parking area 12 in the back, for example, as shown in FIG. 5B, the area number of the handling parking area 12 is captured in the imaging field of view of the camera 41. become. When the image recognition unit 61 recognizes the area number, it proceeds to the next.

  The controller 65 of the vehicle-mounted device 40 determines whether or not the recognized area number matches the area number of the cargo handling parking area 12 included in the guidance information (step S29). Here, if the recognized area number and the area number of the unloading parking area 12 included in the guidance information do not match, the controller 65 informs the monitor 51 via the OSD unit 62 of that fact. It can also be displayed and alert the driver to move the truck 1 to the correct handling and parking area 12.

  When the recognized area number and the area number of the unloading parking area 12 included in the guidance information match, the controller 65 sends a work start notification including the recognized area number and the ID of the truck 1, It transmits to the management apparatus 20 (step S31). Thereafter, the truck 1 is loaded and unloaded on the truck 1 while the truck 1 is parked in the unloading and parking area 12.

  On the other hand, the controller 25 of the management device 20 is waiting to receive a work start notification (step S32). When the work start notification is received, the controller 25 performs an arrival confirmation process (step S34).

  In this arrival confirmation process, it is confirmed that the truck 1 has arrived at the designated handling parking area by matching the area number included in the work start notification with the area number of the handling parking area 12 included in the guidance information. Is done. After this confirmation, when the two area numbers match, the controller 25 switches the usage status of the cargo handling parking area 12 in the usage status table 26 of the storage unit 24 from being used (1) to being used (2). . That is, here, the usage status of the cargo handling parking area 12 is determined as being in use.

  After performing the arrival confirmation process, the controller 25 of the management device 20 waits to receive a work end notification as shown in FIG. 7 (step S36).

  On the other hand, as shown in FIG. 7, the controller 65 of the vehicle-mounted machine 40 is waiting for the work to be completed (step S37). When the driver operates the control panel 52 and inputs the end of work, the controller 65 of the vehicle-mounted machine 40 gives the management device 20 the ID number of the truck 1 and the area number of the unloading parking area 12. A work end notification including is transmitted (step S39). When the work end notification is received, the controller 25 of the management device 20 performs usage status update processing (step S40).

  In this usage status update process, the controller 25 uses the usage status of the handling parking area 12 when the truck 1 is not registered in the queue 27 of the handling parking area 12 of the storage unit 24. When medium (2) is switched to empty (0) and truck 1 is registered in queue 27, the usage status of the unloading parking area 12 is changed from being used (2) to being reserved for use (1) Switch to.

  Further, when the ID of the truck 1 is registered in the queue 27 of the handling parking area 12 of the storage unit 24 (Yes in step S42), the controller 25 obtains the ID number of the truck 1 from the queue 27. By deleting the queue 27, the queue 27 is updated (step S44). Subsequently, the controller 25 includes the area number and the like of the unloading parking area 12 for the vehicle-mounted machine 40 mounted on the truck 1 having the highest priority among the trucks 1 registered in the queue 27. Guidance information is generated (step S46). Next, the controller 25 transmits the generated guidance information to the vehicle-mounted device 40 mounted on the truck 1 having the highest priority (Step S48). After the end of step S48 and when the ID of the truck 1 is not registered in the queue 27 of the cargo handling parking area 12 of the storage unit 24 (No in step S42), the controller 25 ends the process.
