[0002] Conventionally, there is known a business in which a plurality of vehicles are used to patrol a plurality of predetermined locations and perform work at each location (for example, route delivery, garbage collection, etc.). Patent documents 1 and 2 describe a configuration in which, as a result of a vehicle inspection before the start of work, the vehicles are controlled to operate if no problems are found. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-226500 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-199696 Summary of the Invention [Problem to be solved by the invention]

[0004] With conventional technology, if there is a problem with the inspection results, the vehicle will not operate. The vehicle may be in a state where it is not possible to operate, or in a state where it is possible to operate but requires caution. It is not easy to determine whether or not the operation plan needs to be revised based on the results of inspections covering multiple items. The present invention has been made in consideration of the above-mentioned problems, and aims to provide a technology that automatically determines whether or not an operation plan needs to be modified based on inspection results. [Means for solving the problem]

[0005] In order to achieve the above-mentioned objective, the operation management system includes an inspection result acquisition unit that acquires the results of inspections conducted on a vehicle that is planned to patrol multiple predetermined locations before the plan is executed, and a correction necessity determination unit that determines whether or not the operation plan planned for the vehicle needs to be corrected based on the inspection results.

[0006] That is, the operation management system can automatically determine whether or not the operation plan needs to be modified based on the inspection results of the inspection performed before the operation plan is executed. [Brief explanation of the drawings]

[0007] [Figure 1] FIG. 1 is a block diagram showing the configuration of a traffic management system. [Figure 2] FIG. 2A is a diagram showing an example of a vehicle DB, and FIG. 2B is a diagram showing an example of an operation plan DB. [Figure 3] 10 is a flowchart showing a traffic management process. DETAILED DESCRIPTION OF THE INVENTION

[0008] Here, the embodiments of the present invention will be described in the following order. (1) Configuration of the traffic control system: (2) Traffic management processing: (3) Other embodiments:

[0009] (1) Configuration of the traffic control system: FIG. 1 is a block diagram showing the configuration of a traffic management system 10 according to the present invention. In this embodiment, the traffic management system 10 is a system that manages the operation of multiple vehicles that perform garbage collection work, and cooperates with a worker terminal 50, a manager terminal 60, a repairman terminal 70, and a terminal of an external contractor (not shown). The garbage collection work involves visiting multiple predetermined garbage collection points, loading garbage onto a collection vehicle at each garbage collection point, and transporting it to a garbage treatment facility. Garbage collection vehicles are managed by local governments and the like, and there are multiple garbage collection vehicles, including spare vehicles for loaners. Each garbage collection vehicle is identified and managed by a vehicle ID.

[0010] The worker terminal 50 is a portable terminal (which may be, for example, a tablet terminal) used by one worker per garbage collection vehicle, and is used by the worker who drives the garbage collection vehicle and the worker who rides in the garbage collection vehicle to collect garbage. Because there are multiple garbage collection vehicles, there are multiple worker terminals 50, but FIG. 1 shows only one of them. The manager terminal 60 is a terminal used by the manager of the garbage collection work. If there are multiple managers, there may also be multiple manager terminals 60, but FIG. 1 shows only one of them. The repairperson terminal 70 is a terminal used by a repairperson in charge of repairing minor malfunctions of the garbage collection vehicle. There may also be multiple repairperson terminals 70. Note that the terminal used by the person in charge of the external repair company is not shown in FIG. 1.

[0011] The worker terminal 50 includes a communication unit 50a, a GNSS receiving unit 50b, a control unit 50c, and a user I / F unit 50d. The control unit 50c includes a CPU, ROM, RAM, and a recording medium, and the CPU can execute various programs, including a worker terminal control program, that are recorded in the ROM or recording medium.

[0012] The communication unit 50a includes a communication circuit for wireless communication with other devices. The worker terminal 50 can communicate with the operation control system 10 via the communication unit 50a. The user I / F unit 50d is an interface unit through which a user (worker) inputs instructions and provides various information to the user. The user I / F unit 50d includes a touch panel display, switches, a speaker, and the like (not shown). That is, the user I / F unit 50d includes an image and audio output unit and a user instruction input unit. The GNSS receiver 50b is a device that receives signals from a Global Navigation Satellite System. The GNSS receiver 50b receives radio waves from navigation satellites and outputs signals for calculating the position of the worker terminal 50 via an interface (not shown). By executing the worker terminal control program, the control unit 50c acquires these signals and obtains the position of the worker terminal 50.

[0013] Before starting a garbage collection operation, each worker is required to inspect each garbage collection vehicle (pre-trip inspection). The control unit 50c executes the worker terminal control program to display a checklist of pre-trip inspection items on the display of the user I / F unit 50d. The worker operates the touch panel to input their own worker ID and the vehicle ID of the garbage collection vehicle to be inspected into the worker terminal 50. The worker also inspects the areas indicated by each inspection item and inputs the results of each inspection item (no problems, presence of problems, etc.) by operating the touch panel. The inspection items include, for example, general vehicle-related inspection items (engine, tires, brakes, remaining gasoline, air conditioner, power windows, etc.) as well as inspection items related to the garbage loading and compaction mechanisms. Once the inspection results for all inspection items have been input, the control unit 50c transmits the inspection results to the traffic management system 10. The inspection results transmitted to the traffic management system 10 include the vehicle ID of the garbage collection vehicle that underwent the pre-trip inspection, the worker ID of the worker who performed the pre-trip inspection, the results of each inspection item, and the inspection date and time. Furthermore, as will be described later, when the control unit 50c receives an operation plan from the operation management system 10, it displays the operation plan on the display.

[0014] By executing the operator terminal control program, the control unit 50c references the garbage collection vehicle operation plan distributed from the operation management system 10 and acquires the locations of garbage collection points defined in the operation plan. The control unit 50c displays a map on the display and displays the current location of the garbage collection vehicle and the garbage collection points around the current location on the map. The operator driving the garbage collection vehicle can understand the garbage collection points defined in the operation plan by referring to this map. The control unit 50c acquires the time from a timing unit (not shown). Based on the location and time, if the location of the operator terminal 50 (i.e., the current location of the garbage collection vehicle) remains within a predetermined range of a garbage collection point for a predetermined time or longer, the control unit 50c assumes that the garbage collection vehicle used by the operator terminal 50 has stopped at the garbage collection point and that the operator has performed garbage collection work. The control unit 50c distinguishes between garbage collection points where garbage collection has been completed and those where garbage collection has not been completed on the map, for example, by displaying icons of different colors.

[0015] The administrator terminal 60 includes a communication unit 60a, a control unit 60c, and a user I / F unit 60d. The control unit 60c includes a CPU, ROM, RAM, and a recording medium, and the CPU can execute various programs including an administrator terminal control program recorded in the ROM or recording medium. The communication unit 60a includes a communication circuit for wireless communication with other devices. The administrator terminal 60 can communicate with the operation control system 10 via the communication unit 60a. The user I / F unit 60d is an interface unit that allows the user (administrator) to input instructions and provides the user with various information, and includes a touch panel display, switches, a speaker, etc. (not shown).

[0016] By executing the manager terminal control program, the control unit 60c can obtain the inspection results of the pre-operation inspection of each garbage collection vehicle and an approval request for the operation plan associated with the garbage collection vehicle, and display them on the display of the user I / F unit 60d. The manager can refer to the inspection results of each garbage collection vehicle displayed on the display. The approval request is sent from the operations management system 10 to the manager terminal 60 when there are no problems with the garbage collection vehicle that would prevent it from being operated. Upon receiving the approval request, the manager terminal 60 displays an approval button on the display to obtain the manager's approval. When the manager touches the approval button, the control unit 60c sends a message to the operations management system 10 that the manager has approved.

[0017] The repairperson terminal 70 includes a communication unit 70a, a control unit 70c, and a user I / F unit 70d. The control unit 70c includes a CPU, ROM, RAM, and a recording medium, and the CPU can execute various programs, including a repairperson terminal control program, stored in the ROM or recording medium. The communication unit 70a includes a communication circuit for wireless communication with other devices. The repairperson terminal 70 can communicate with the operation control system 10 via the communication unit 70a. The user I / F unit 70d is an interface unit that allows the user (repairperson) to input instructions and provides the user with various information, and includes a touch panel display, switches, a speaker, etc. (not shown).

[0018] By executing the repair technician terminal control program, the control unit 70c receives from the traffic management system 10 the vehicle ID of the vehicle needing repair and a repair request including the inspection results, and displays this on the display of the user I / F unit 70d. The repair technician confirms the contents of the repair request and repairs the problem area of ​​the garbage collection vehicle with that vehicle ID. Once the repair is complete, the repair technician inputs into the repair technician terminal 70 that the repair of the garbage collection vehicle with that vehicle ID has been completed, and the control unit 70c sends a repair completion notification to the traffic management system 10. Upon receiving the repair completion notification, the vehicle whose repair has been completed will be managed by the traffic management system 10 as a spare vehicle (for use as a loaner vehicle).

[0019] The operation management system 10 includes a control unit 20 equipped with a CPU, RAM, ROM, etc., a recording medium 30, and a communication unit 41, and can execute programs stored in the recording medium 30 or ROM using the control unit 20. In this embodiment, the program that can be executed is an operation management program 21. The communication unit 41 includes a circuit for communicating with other devices, and the control unit 20 can communicate with a worker terminal 50, a manager terminal 60, and a repair person terminal 70 via the communication unit 41.

[0020] The recording medium 30 stores a vehicle DB 30a and an operation plan DB 30b. The vehicle DB 30a is a database that manages information about each garbage collection vehicle. FIG. 2A is a diagram showing an example of the configuration of the vehicle DB 30a. As shown in the figure, in the vehicle DB 30a in this embodiment, information indicating the vehicle status, such as whether the vehicle is assigned to an operation plan or is a spare vehicle for a loaner, is associated with each vehicle ID. The vehicle DB 30a also stores, in association with the vehicle ID, the results of each inspection item in the pre-operation inspection of the garbage collection vehicle associated with that vehicle ID, the inspection date and time, and the operator ID of the inspector. The vehicle DB 30a may store not only the most recent inspection results but also a history of inspection results over a certain period of time.

[0021] The operation plan DB 30b stores operation plans for each garbage collection vehicle. FIG. 2B is a diagram showing an example of the configuration of the operation plan DB 30b. As shown in FIG. 2B, in this embodiment, the operation plan DB 30b stores the vehicle ID of each garbage collection vehicle and the worker ID of the worker who will implement the operation plan, in association with a plan ID for identifying the operation plan. In addition, the identification symbol of each garbage collection point and the location of that point are recorded in association with the plan ID.

[0022] By executing the operation management program 21, the control unit 20 can function as an inspection result acquisition unit 21a and a correction necessity determination unit 21b. The control unit 20 uses the function of the inspection result acquisition unit 21a to acquire the results of inspections conducted before the execution of a plan for vehicles scheduled to patrol multiple predetermined locations. In other words, the control unit 20 acquires, from each worker terminal 50, the inspection results of the pre-operation inspections conducted for each garbage collection vehicle on the day the garbage collection work is to be performed. The control unit 20 stores the inspection results acquired from each worker terminal 50 in the vehicle DB 30a.

[0023] The control unit 20 determines, based on the inspection results, whether or not the operation plan planned for the vehicle needs to be modified using the function of the modification necessity determination unit 21b. If it is determined based on the inspection results of the multiple vehicles that there is an inoperable vehicle among the multiple vehicles, the control unit 20 modifies at least one operation plan so that the multiple vehicles patrol all scheduled locations without using the inoperable vehicle. For each inspection item, whether or not to determine that an abnormality in the item indicates an inoperable problem is predetermined. In this embodiment, the control unit 20 considers a vehicle that does not have an abnormality in an item corresponding to an inoperable problem as an inoperable vehicle and automatically assigns a substitute vehicle. Specifically, the control unit 20 refers to the vehicle DB 30a to identify the vehicle ID of the garbage collection vehicle with the inoperable problem, and further refers to the operation plan DB 30b to identify the plan ID of the operation plan associated with the vehicle ID. The control unit 20 then cancels the association between the vehicle ID and the corresponding plan ID. The control unit 20 refers to the vehicle DB 30a to extract a spare vehicle and assigns the vehicle ID of the spare vehicle to the aforementioned plan ID. In this embodiment, the control unit 20 corrects the operation plan by automatically arranging for a replacement vehicle in this way.

[0024] The control unit 20 notifies the worker terminal 50 operated by the worker who inspected the garbage collection vehicle that had a problem that made it impossible to operate of the vehicle ID of the vehicle newly assigned to the operation plan and sends a request to perform a pre-operation inspection of that vehicle. In response to the inspection request, the worker performs a pre-operation inspection of the newly assigned vehicle, and the worker terminal 50 sends the inspection results to the operation management system 10. The control unit 20 then repeats the processing of the inspection result acquisition unit 21a and the processing of the correction necessity determination unit 21b described above.

[0025] Furthermore, for garbage collection vehicles with problems that prevent them from being operated, the control unit 20 sends a repair request to a terminal (not shown) of an external repair company. The repair request to the external repair company may be sent, for example, by email, fax, or push notification of a dedicated application provided by the operation management system 10. A garbage collection vehicle undergoing repair by an external repair company is managed in the vehicle DB 30a as a vehicle under repair. Once the repair is complete, the vehicle is managed in the vehicle DB 30a as a vehicle other than one under repair, for example, as a spare vehicle.

[0026] When the control unit 20 determines, based on the vehicle inspection results, using the function of the correction necessity determination unit 21b, that the vehicle is operable but requires repair, the control unit 20 notifies the repair technician of the inspection results of the vehicle requiring repair. As described above, for each inspection item, it is predetermined whether or not to determine that a problem that would make the vehicle inoperable if the item is not normal. If the inspection results show that an item other than the item that would be determined to be an issue that would make the vehicle inoperable if the inspection results are not normal, the control unit 20 considers the vehicle to be a vehicle requiring repair. In this case, the control unit 20 continues the day's operation using the vehicle as is, but after the operation is completed, sends a repair request to the repair technician terminal 70 so that the repair technician can repair the vehicle. The repair request includes the vehicle ID of the garbage collection truck and the inspection results.

[0027] For garbage collection vehicles that are determined to be operable as a result of the inspection, the control unit 20 transmits the contents of the operation plan associated with the vehicle, the inspection results of the day's pre-operation inspection, and an approval request to the manager terminal 60. When the manager receives a notification that approval has been granted in response to the approval request, the control unit 20 transmits the operation plan planned for the vehicle (i.e., the vehicle associated with the operation plan DB 30b) to the worker terminal 50 used by the worker who performed the pre-operation inspection of the vehicle. As a result, the garbage collection points indicated in the operation plan can be displayed on the worker terminal 50 operated by the worker of the vehicle, and the vehicle is ready to begin garbage collection work.

[0028] As described above, according to this embodiment, it is possible to automatically determine whether or not an operation plan needs to be modified based on the inspection results of an inspection performed before the operation plan is executed, thereby reducing the burden on managers and workers.

[0029] (2) Traffic management processing: Next, the operation management process executed by the control unit 20 will be described with reference to Fig. 3. The operation management process is executed when the control unit 20 receives the inspection results of a pre-operation inspection for one vehicle. When the operation management process starts, the control unit 20 acquires the inspection results of the pre-operation inspection using the function of the inspection result acquisition unit 21a (step S100). That is, the control unit 20 refers to the vehicle DB 30a and acquires the inspection results of the pre-operation inspection performed on the target garbage collection vehicle.

[0030] Next, the control unit 20 determines whether or not there is a problem in the inspection results using the function of the correction necessity determination unit 21b (step S105). That is, the control unit 20 refers to each item in the inspection results and determines whether or not there is an item with an abnormality. If it is determined in step S105 that there is a problem, the control unit 20 determines whether or not there is a problem that will prevent operation using the function of the correction necessity determination unit 21b (step S110). That is, for each inspection item, it is predetermined whether or not there is an item that will prevent operation if an abnormality is found, and if the result shows that there is an abnormality in an item that will prevent operation, the control unit 20 determines that there is a problem that will prevent operation.

[0031] If it is determined in step S110 that there is a problem that makes the operation impossible, the control unit 20 modifies the operation plan using the function of the correction necessity determination unit 21b (step S120) and sends a repair request to the terminal of an external repair company (not shown) (step S125). That is, the control unit 20 cancels the association between the vehicle ID of the target garbage collection truck and the plan ID of the operation plan in the operation plan DB 30b, and newly associates the vehicle ID of the spare vehicle with that plan ID. Then, the control unit 20 notifies the worker terminal 50 of the worker who was performing the pre-operation inspection of the vehicle with the canceled vehicle ID of the newly associated spare vehicle, and guides the worker to perform a pre-operation inspection in order to operate the vehicle. The control unit 20 also sends a repair request for the vehicle that is no longer operable to the terminal of the external repair company. After executing step S125, the control unit 20 returns to step S100 and waits for the inspection results of the pre-operation inspection of the newly associated vehicle to be transmitted from the worker terminal 50.

[0032] If it is determined in step S110 that there is no problem that would make the vehicle inoperable, the control unit 20 uses the function of the correction necessity determination unit 21b to send the inspection results of the vehicle requiring repair to the repair person terminal 70 (step S115). In this case, after the garbage collection work for the day is completed, the repair person will repair the vehicle.

[0033] If it is determined in step S105 that there is no problem, or after executing step S115, the control unit 20 obtains approval from the manager using the function of the correction necessity determination unit 21b (step S130). Specifically, the control unit 20 transmits the results of the pre-operation inspection of the target vehicle and an approval request for the target vehicle to implement the corresponding operation plan to the manager terminal 60. When the manager terminal 60 receives the approval request, it displays an approval button on the display of the user I / F unit 60d. When the manager touches the approval button, a message that the manager has approved is transmitted from the manager terminal 60, and the control unit 20 obtains approval from the manager.

[0034] Next, the control unit 20 uses the function of the correction necessity determination unit 21b to send the operation plan to the worker terminal 50 (step S135). As a result, the worker terminal 50 is able to display a map showing waste collection points based on the operation plan, and the waste collection vehicle equipped with the worker terminal 50 is able to start waste collection work in accordance with the operation plan.

[0035] (3) Other embodiments: The above embodiment is one example for carrying out the present invention, and various other embodiments can be adopted. For example, the operator terminal 50 may be a portable terminal or an in-vehicle terminal. At least a part of the inspection result acquisition unit 21a and the correction necessity determination unit 21b that constitute the operation management system may be separated into multiple devices. For example, part of the function of the correction necessity determination unit 21b (such as determining whether or not there is an abnormality based on the inspection results) may be realized by the operator terminal. Of course, part of the configuration of the above embodiment may be omitted, and the order of processing may be changed or omitted.

[0036] The operation plan may be any plan that specifies traveling to predetermined locations and performing work at each location, and the content of the work may be any. Therefore, in addition to garbage collection work, the present invention may also be applied to delivery of goods to predetermined stores such as convenience stores. Furthermore, the operation management system may target one vehicle or multiple vehicles.

[0037] If the correction necessity determination unit determines, based on the inspection results of the multiple vehicles, that there is an inoperable vehicle among the multiple vehicles, it is sufficient that it corrects at least one operation plan so that the multiple vehicles visit all of the scheduled patrol points without using the inoperable vehicle. As in the above embodiment, one operation plan may be corrected to replace the inoperable vehicle with a spare vehicle. Alternatively, if there is no spare vehicle, the operation plan may be corrected so that the scheduled patrol points for the inoperable vehicle are assigned to the remaining operable vehicles. For example, all of the scheduled patrol points and the number of vehicles may be input into a known VRP algorithm to obtain an output of the patrol order of each patrol point for each patrol group that minimizes cost (e.g., travel time or travel distance between two points). This output may be applied to the operation plan of each vehicle to correct the operation plan.

[0038] The correction necessity determination unit may be configured to notify each worker of the operation plan for each vehicle if it is determined that all vehicles are operable based on the inspection results of multiple vehicles. For example, if a normal operation is performed with M vehicles (M is an integer greater than or equal to 3) but one of the vehicles is determined to be inoperable, and operation is required with (M-1) vehicles, and operation plans other than the inoperable vehicle's operation plan also need to be modified, the correction necessity determination unit notifies each vehicle of the modified operation plan once it has confirmed that all (M-1) vehicles other than the inoperable vehicle are operable and that modified operation plans have been assigned to each vehicle. For example, if a portion of the (M-1) vehicles, i.e., L vehicles (L is an integer greater than or equal to 1 and less than (M-1)), are notified of the pre-modification operation plan and the notified vehicle begins operating according to the pre-modification operation plan, the remaining (M-1-L) vehicles must cover the patrol points for the inoperable vehicle. This can result in an increased workload for certain vehicles. However, once it is confirmed that all vehicles (M-1) other than the inoperable vehicles are operable and that the revised operation plan has been assigned to each vehicle, the revised operation plan can be notified to each vehicle, thereby reducing the possibility of the workload on each vehicle becoming unbalanced.

[0039] Furthermore, the correction necessity determination unit may be configured to notify the manager that, when it determines that there is an inoperable vehicle among the plurality of vehicles based on the inspection results of the plurality of vehicles, the correction necessity determination unit notifies the manager that at least the operation plan related to the inoperable vehicle needs to be corrected. This configuration reduces the effort and burden on the manager in determining whether the operation plan needs to be corrected. Upon receiving such a notification, the manager can easily recognize which operation plan needs to be corrected. Then, the manager can manually correct the operation plan by replacing the inoperable vehicle with a loaner vehicle or, if a loaner vehicle is not available, by allocating the patrol points of the inoperable vehicle to another vehicle.

[0040] If the pre-operation inspection reveals that the vehicle is operable but its remaining fuel or charge is less than the amount of fuel required to execute the operation plan for that day, the operation plan for the vehicle may be modified. For example, the operation plan for the vehicle may be modified so that the vehicle passes through a refueling facility along the way. Alternatively, the operation plan may be modified so that some of the routes of the vehicle with little remaining fuel are allocated to other vehicles. In the above embodiment, the local government may have multiple bases for garbage collection vehicles. In this case, a spare vehicle for replacement vehicles may be provided at each base, and the number of spare vehicles may be managed (recorded in the vehicle DB) for each base.

[0041] Furthermore, the techniques of the present invention can also be applied as programs or methods. The above-described systems, programs, and methods may be realized as standalone devices or may be realized using components shared with various parts of a vehicle, and thus include various aspects. They can also be modified as appropriate, such as being partly software and partly hardware. Furthermore, the invention can also be realized as a recording medium for a program that controls the system. Of course, the recording medium for the program may be a magnetic recording medium or a semiconductor memory, and any recording medium developed in the future can be considered in the same way.
