In a case where a plurality of operation vehicles patrol on one patrol route, display means of the on-vehicle terminal (or a management server) of each patrolling operation vehicle displays the patrolled locus of the own vehicle (observing vehicle) on a map, and displays the patrolled locus of other vehicle on the map. Thus, the progress of patrol tasks on the patrol route, including the operation progress of the other vehicles in addition to the observing vehicle, can be determined, and a section where the patrol task on the patrol route is completed can be determined in real time. Also, a redundant patrol in a section where patrol task on the patrol route is already completed is prevented and an improvement in operation efficiency can be achieved.SELECTED DRAWING: Figure 6

Description

[Technical Field]

[0001] The present invention relates to a patrol work support management system that supports and manages the patrol work of each work vehicle in patrol work in which the work vehicle travels along a predetermined patrol route and performs predetermined tasks. [Background technology]

[0002] A "patrol work" refers to a task in which a work vehicle travels along a predetermined patrol route while performing a predetermined work (a job or task that is performed continuously in relation to an occupation, business, etc.). Examples of patrol work include garbage collection, delivery of letters, packages, or goods, and road sweeping. In order to improve the efficiency of such patrol work, patrol work support management systems have been proposed, for example, as described in Patent Documents 1 to 3.

[0003] Patent Document 1 describes a patrol operation support management system for refuse collection operations. This system includes a management server and a worker terminal device. The worker terminal device acquires a list of refuse stations (STs) along a refuse collection route from the management server, displays a map on a touch panel display (TD), and marks each ST location on the map with a "●" mark based on the ST information in the ST list. The ST information included in the ST list is also displayed as a list on the side of the map on the TD screen. A worker can select a ST by touching the ST information included in the ST list, and a ST photo and guide information for the selected ST are displayed on the TD or output from a speaker. This makes it easier to locate even difficult-to-find STs, allowing workers to reliably perform collection work at each ST even when working on the route for the first time. As a result, a high level of uniformity in refuse collection services is achieved, regardless of the worker's personal proficiency or experience.

[0004] Patent Document 2 describes a patrol operation support management system for refuse collection operations. This system includes a server (20) and an on-board device (30) (see Figures 1 and 2 of the document). The on-board device (30) includes an information acquisition means (11) that acquires vehicle status information, including the vehicle's position, direction, speed, and reverse information, at predetermined time intervals via measuring devices (GPS receiver, gyro sensor, vehicle speed sensor, and reverse sensor) mounted on the vehicle, a vehicle position acquisition means (12), and a display means (13). The server (20) includes a trajectory information generation means (21) that generates a trajectory of the vehicle on pre-stored map information based on the vehicle status information acquired by the information acquisition means, including roads present in the map information and routes other than roads present in the map information, and generates additional information indicating all or part of the vehicle's U-turn positions, reverse sections, stopping positions, and stopping directions on the trajectory, and generates vehicle trajectory information by adding the additional information to the trajectory. The in-vehicle device (30) displays map information around the current location on a display device (see Figure 7 of the document) and displays the vehicle's trajectory R superimposed on the map. When displaying the trajectory R, ​​various displays are made based on the detailed driving information and collected location identification information. For example, the vehicle's forward section is displayed with a dashed line, the U-turn position is displayed with a solid line, and the reverse section is displayed with a dashed line. In addition, specific symbols and text such as "This is a reverse section" and "Please make a U-turn" are displayed for each section and position. This allows even a novice driver to drive as efficiently as a veteran driver.

[0005] Patent Document 3 describes a mobile operation support management system (waste collection support system) for refuse collection operations. This system includes a navigation device (navigation system) (100) mounted on a collection vehicle, an administrator terminal (200) that manages waste collection, and a server (10) that can communicate with these (see Figure 1 of the document). The server (10) includes a waste collection determination unit (21a) that determines whether each collection station (scheduled collection location) is a collection completion point or a collection incomplete point, and a display control unit (21b) that displays the collection station on the display of the navigation device (100). The display control unit (21b) controls the display of a map on the navigation device (100) via a communication line. A map is drawn on the display of the navigation device (100), and collection station icons are drawn on the map (see Figures 2 and 3 of the document). The waste collection determination unit (21a) acquires the current location of the collection vehicle from the navigation device (100) and considers waste collection at a collection station to be complete when the distance between the current location of the collection vehicle and the collection station is within a predetermined distance. The display control unit (21b) displays a map on the display at a scale based on the collection stations where collection has not yet been completed (a scale where the number of collection points where collection has not yet been completed is at least equal to the set number of collection points). This reduces the need for the collector to check the collection station for a collection point where collection has not yet been completed each time collection is completed. Furthermore, when waste collection is completed at a collection station for a collection point where collection has not yet been completed, the color of the icon for that collection station is changed or the display of that collection station is erased. This allows the collector to easily determine whether the collection station displayed on the display is a collection point where collection has been completed or a collection point where collection has not yet been completed.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2020-129374 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-071072 [Patent Document 3] Japanese Patent Application Publication No. 2023-109373 [Patent Document 4] Patent Publication No. 2021-156581 [Non-patent literature]

[0007] [Non-Patent Document 1] Kaoru Suzuki, "Garbage Collection Methods," National Institute for Environmental Studies News, Vol. 39, No. 4, pp. 11-14, 2020. Summary of the Invention [Problem to be solved by the invention]

[0008] In Japan, garbage collection, which is one type of mobile garbage collection service, can be broadly divided into "station collection" and "door-to-door collection" (Non-Patent Document 1). "Station collection" refers to a system in which multiple households share a garbage collection point (garbage station: a temporary collection location for disposing of and collecting general waste (household garbage)), and garbage is collected by a collection company. "Door-to-door collection" refers to a system in which garbage is left in front of each house and collected by a collection company.

[0009] The patrol work support management systems described in Patent Documents 1 to 3 are all systems that support or manage garbage collection work by visiting garbage collection sites, and can be said to be based on station collection. On the other hand, in the case of door-to-door collection, a garbage truck (a work vehicle specialized for collecting garbage and transporting it to a disposal facility) travels along a predetermined route and collects garbage placed in front of each home or business along the route (within the premises of a home or business facing the road). In this case, too, a navigation system is used to guide the route (see Patent Document 4).

[0010] In actual practice, in order to shorten the overall work time, multiple refuse trucks may be used to cover a single door-to-door collection route. In such cases, the command center that instructs each refuse truck on its operation determines which points and sections each truck should cover.

[0011] However, when there are a large number of refuse compactor vehicles operating at the same time, it is a tedious task for the command center to issue instructions to each refuse compactor vehicle regarding the patrol start point and patrol section, which places a heavy burden on the command center commander (the person who issues instructions to each refuse compactor vehicle).It is also prone to command errors, such as accidentally issuing duplicate instructions for sections that have already been collected.The above-mentioned conventional patrol work support management system is insufficient to deal with these problems, and a new solution was required.

[0012] Therefore, an object of the present invention is to provide a patrol work support management system that reduces the burden on the commander who issues commands to each work vehicle when patrol work is performed by using multiple work vehicles to patrol a single route, and supports and manages each work vehicle to efficiently perform patrol work. [Means for solving the problem]

[0013] A first configuration of the patrol work support management system according to the present invention is a patrol work support management system that supports and manages the patrol work of each work vehicle in a patrol work in which the work vehicle travels along a predetermined patrol route and performs predetermined work, A management server; an on-board terminal device that is mounted on each of the work vehicles and has a positioning device that measures the current position and is capable of communicating with the management server via a communication line; The in-vehicle terminal device a vehicle position transmitting means for transmitting current position information detected by the positioning device at each time to the management server; It is equipped with The management server a work vehicle information storage means for storing information about each of the work vehicles, the information including information about the route that the work vehicle is currently traveling; a work vehicle trajectory storage means for storing the patrolled trajectories of each of the work vehicles; a work vehicle trajectory update means for receiving position information of each work vehicle transmitted from the on-board terminal device mounted on each work vehicle, and storing the position of the work vehicle and the time when the work vehicle is at that position as a traveled trajectory in the work vehicle trajectory storage means; It is equipped with The management server or the in-vehicle terminal device a display device; a map information storage means for storing map information; a travel route information storage means for storing information about the travel route; a map display means for displaying a map on the display device; a route display means for reading the route from the route information storage means and displaying it on the map displayed on the display device; an observation vehicle track display means for displaying an observation vehicle completed track, which is the completed track of a certain one of the work vehicles (hereinafter referred to as "observation vehicle"), on a map displayed on the display device; an other vehicle trajectory acquisition means for acquiring other vehicle trajectory, which is the trajectory of another work vehicle (hereinafter referred to as "other vehicle") other than the observation vehicle that patrols the patrol route currently patrolled by the observation vehicle, on the patrol route; another vehicle locus display means for displaying the other vehicle's completed patrol locus acquired by the other vehicle locus acquisition means on the map displayed on the display device so as to be distinguishable from the observation vehicle's completed patrol locus; The present invention is characterized by the following.

[0014] According to this configuration, when patrol work on one patrol route is carried out by multiple work vehicles, by displaying the patrol locus of other vehicles in addition to the patrol locus of the observation vehicle on the display device, it is possible to grasp the progress of patrol work on the patrol route, including the work progress of other vehicles in addition to the observation vehicle, and to grasp in real time the sections on the patrol route where patrol work has been completed. This prevents redundant patrols of sections where patrol work has already been completed, and improves work efficiency.

[0015] Here, "route work" refers to work in which a work vehicle travels along a designated route while performing designated tasks or works, including garbage collection, delivery of letters, parcels, or goods, and road sweeping. "Traveling route" refers to the route traveled around each location to perform designated work. "Loading" refers to loading an on-board terminal device onto a work vehicle or installing an on-board terminal device on a work vehicle, and also includes cases where a worker carrying the on-board terminal device is riding on the work vehicle. "Positioning device" refers to a device that determines the position of a moving object, and includes GNSS (Global Navigation Satellite System), which performs positioning using a satellite positioning system, and base station positioning using base station positioning (which calculates the distance from a telecommunications carrier's base station to a mobile terminal and determines the terminal's location).

[0016] The work vehicle trajectory update means stores the position of the work vehicle and the time when the work vehicle is at that position in the work vehicle trajectory storage means as a patrolled trajectory, but the "time at that position" referred to here may be the time when the position information was detected by the positioning device and transmitted to the management server by the vehicle position transmission means, and the time included in that position information may be used as the "time at that position," or the time when the management server receives the position information transmitted from the on-board terminal device may be used as the "time at that position." This is because it is generally considered that there is a small time lag between the time when position information is detected by the positioning device, the time when that position information is transmitted to the management server, and the time when that position information is received by the management server.

[0017] A second configuration of the mobile work support management system according to the present invention is the first configuration, wherein the in-vehicle terminal device: the display device, the map information storage means, the tour route information storage means, the map display means, the tour route display means, the observation vehicle track display means, the other vehicle track acquisition means, and the other vehicle track display means; It is equipped with the observation vehicle trajectory display means acquires the current position detected by the positioning device at each time, and displays the observation vehicle completed patrol trajectory, which is the patrol trajectory of the observation vehicle, which is the work vehicle on which the vehicle-mounted terminal device is mounted, on a map displayed on the display device; The other vehicle trajectory acquisition means acquires, in real time from the management server, other vehicle trajectories that are trajectories of other vehicles traversing the patrol route on which the observation vehicle is currently patrolling. It is characterized by:

[0018] According to this configuration, when patrol work on one patrol route is carried out by multiple work vehicles, the worker in the observation vehicle (in this case, the observation vehicle refers to the worker's own vehicle (the work vehicle equipped with an on-board terminal device)) can grasp the progress of patrol work on the patrol route, including the work progress of other vehicles, by displaying the patrol work completed by the observation vehicle on the display device, and can also grasp in real time the sections on the patrol route where patrol work has been completed. This prevents the worker in the observation vehicle from patrolling sections where patrol work has already been completed, thereby improving work efficiency.

[0020] With this configuration, the predicted progress trajectory of the observation vehicle as it moves along the patrol route from its current position within a specified time is displayed, allowing workers aboard the observation vehicle to visually grasp how much progress will be made in the patrol work within the specified time, making it easier to decide whether or not to request a support vehicle to share the patrol work on the patrol route.

[0021] Here, "estimated operating speed" refers to the operating speed when a work vehicle operates at each point on each patrol route, or the required time from the previous point. "Each point on the patrol route" refers to the end points of each subsection when the patrol route from its start point to its end point is divided into small subsections. "Required time from the previous point" refers to the required time from the start point to the end point of a certain subsection when the patrol route from its start point to its end point is divided into small subsections and the end points of each subsection are considered to be "each point on the patrol route." (Note that, strictly speaking, "required time from the previous point" is not a speed, but because it is essentially proportional to the speed of the subsection, it will also be referred to as "estimated operating speed.")

DETAILED DESCRIPTION OF THE INVENTION

[0038] Hereinafter, embodiments of the present invention will be described with reference to the drawings. [Example]

[0039] In the first embodiment, a mobile work support management system for garbage collection work is shown as an example of the mobile work support management system of the present invention. In particular, the mobile work support management system is used when garbage collection work is performed by door-to-door collection (a method in which garbage is placed in front of each house and collected by a garbage collector).

[0040] FIG. 1 is a diagram illustrating the overall configuration of a route work support management system according to a first embodiment of the present invention. The route work support management system of this embodiment includes a management server 1, which is a computer installed in a control center or a data center, and an on-board terminal device 2, which is a computer terminal installed in a work vehicle 4 that performs route work. The "route work" here refers to a garbage collection operation using a door-to-door collection method, and the "work vehicle" here refers to a garbage truck. The on-board terminal device 2 may be a terminal device equipped with a computer that is fixedly installed in the work vehicle 4, such as a car navigation device, or may be a terminal device equipped with a computer that is carried by a worker riding in the work vehicle 4, such as a tablet or smartphone. The on-board terminal device 2 is capable of communicating with the management server 1 via a wireless or wired communication line 3. The on-board terminal device 2 also includes a positioning device 42, such as a Global Navigation Satellite System (GNSS), as described below. The management server 1 is operated by a commander who issues various work instructions to each work vehicle 4, and the on-board terminal device 2 mounted on each work vehicle 4 is operated by a worker who rides in the work vehicle 4 and performs patrol work.

[0041] Figure 2 is a block diagram showing the functional configuration of the management server 1 of Figure 1. In Figure 2, the management server 1 has, as its hardware configuration, a display device 10 and an input device 11. It also has, as its functional configuration, a work vehicle information storage means 12, a map information storage means 13, a patrol route information storage means 14, a work vehicle trajectory storage means 15, a work vehicle trajectory update means 16, a map display means 17, a work vehicle selection means 18, a patrol route display means 19, an observation vehicle trajectory display means 20, another vehicle trajectory acquisition means 21, and another vehicle trajectory display means 22. Each of these functional components is configured as a functional module within the computer by having the computer read and execute a program.

[0042] The display device 10 is a computer display device such as a liquid crystal display or an organic EL display, and the input device 11 is a computer input device such as a keyboard, a mouse, or a touch panel.

[0043] The work vehicle information storage means 12 stores the work vehicle information of each work vehicle. "Work vehicle information" refers to information about a work vehicle, including the identification information (work vehicle ID) of the work vehicle and information about the patrol route that the work vehicle is currently traveling. Here, the "traveling route" refers to the route that the work vehicle takes to travel around each location where food waste collection is performed in order to carry out food waste collection work. The map information storage means 13 stores information about maps (map information). "Map information" includes information about roads, buildings, and landmarks. The road information includes information about the number of lanes, the presence or absence of a median strip, road width, speed limits, one-way streets, etc. The patrol route information storage means 14 stores information about each patrol route (patrol route information). The patrol route information includes the identification information of the patrol route (patrol route ID), information about the tracks (roads, paths, and other passages) that the patrol route passes through, and information about the business operator in charge of the patrol route. The work vehicle locus storage means 15 stores the traveled locus of each work vehicle. A "traveled locus" refers to the path that the work vehicle has taken when it has traveled a patrol route in the past.

[0044] The vehicle trajectory update means 16 receives the position information of each vehicle 4 transmitted from the on-board terminal device 2 mounted on the vehicle 4, and stores the pair (q, t) of the position q of the vehicle 4 and the time t when the vehicle 4 is at that position q in the vehicle trajectory storage means 15 as a trajectory point of the traveled trajectory. The position q = (x, y) is a latitude and longitude coordinate (coordinates of longitude x and latitude y). The traveled trajectory stored in the vehicle trajectory update means 16 is a set of these trajectory points (pair (q i ,t i )) permutation {(q i ,t i)} (i is an index indicating the order in which position information was received from the same vehicle-mounted terminal device 2). Here, if the position information of the vehicle 4 sent from the vehicle-mounted terminal device 2 includes the detection time t of that position information, then that time t is taken to be "the time t when the vehicle 4 is at its position q." If the position information of the vehicle 4 sent from the vehicle-mounted terminal device 2 does not include the detection time t, then the reception time t of that position information is taken to be "the time t when the vehicle 4 is at its position q."

[0045] The map display means 17 reads map information from the map information storage means 13 and displays the map on the display device 10. The work vehicle selection means 18 selects one piece of work vehicle information from the work vehicle information stored in the work vehicle information storage means 15 as work vehicle information for the observation vehicle, in accordance with instructions input by the commander of the management server 1 from the input device 11. The "watching vehicle" here refers to one work vehicle that the commander of the management server 1 is paying attention to. The tour route display means 19 reads out tour route information for the tour route currently being patrolled by the observation vehicle selected by the work vehicle selection means 18 from the tour route information storage means 14, and displays this tour route on the map displayed on the display device 10. Hereinafter, the tour route currently being patrolled by the observation vehicle on the management server 1 side will be referred to as the "watching route."

[0046] The observation vehicle trajectory display means 20 displays the trajectory of the observation route already traveled by the observation vehicle at the current time on the map displayed on the display device 10. The trajectory of the observation route already traveled by the observation vehicle at the current time is called the "observation vehicle trajectory." The other vehicle trajectory acquisition means 21 acquires from the work vehicle trajectory storage means 15 the trajectory of the observation route traveled by work vehicles other than the observation vehicle that are currently patrolling the observation route currently patrolled by the observation vehicle. Work vehicles other than the observation vehicle that are currently patrolling the observation route are called "other vehicles." The trajectory of the observation route already traveled by other vehicles at the current time is called the "other vehicle trajectory." The other vehicle trajectory display means 22 displays the other vehicle trajectory acquired by the other vehicle trajectory acquisition means 21 on the map displayed on the display device 10 so that it is distinguishable from the observation vehicle trajectory.

[0047] FIG. 3 is a block diagram showing the functional configuration of the on-board terminal device 2 of FIG. 1. In FIG. 3, the management server 1 includes, as its hardware configuration, a display device 40, an input device 41, and a positioning device 42. It also includes, as its functional configuration, a vehicle position transmission means 43, a map information storage means 44, a tour route information storage means 45, a vehicle trajectory information storage means 46, a vehicle trajectory information storage means 47, a map display means 48, a tour route selection means 49, a tour route display means 50, a vehicle observation trajectory display means 51, a vehicle trajectory acquisition means 52, and a vehicle trajectory display means 53. Each of these functional components is configured as a functional module within a computer by loading and executing a program into the computer. It is assumed that the on-board terminal device 2 stores the vehicle ID of the vehicle on which the on-board terminal device 2 is installed.

[0048] The display device 40 is a display device of a computer terminal such as a liquid crystal display or an organic EL display. The input device 41 is an input device of a computer terminal such as a touch panel or a pen tablet. The positioning device 42 is a device for locating the position of the in-vehicle terminal device 2, and measures the position (latitude and longitude) of the in-vehicle terminal device 2 in real time using various known methods such as GNSS and base station positioning. The vehicle position transmission means 43 transmits current position information detected by the positioning device 42 at each time to the management server 1 via the communication line 3.

[0049] The map information storage means 44 stores information about maps (map information). The "map information" is the same as the map information stored in the map display means 17 of the management server 1. The tour route information storage means 45 stores information about each tour route (tour route information). The host vehicle trajectory information storage means 46 stores the toured trajectory of the work vehicle 4 on which the on-board terminal device 2 is mounted. Hereinafter, the work vehicle 4 on which the on-board terminal device 2 is mounted will be referred to as the "host vehicle." The "host vehicle" corresponds to the "monitoring vehicle" on the side of the on-board terminal device 2. Furthermore, on the side of the on-board terminal device 2, the tour route that the host vehicle is currently patrolling (or about to patrol) is referred to as the "monitoring route." The other vehicle trajectory information storage means 47 stores the toured trajectories of each work vehicle other than the host vehicle that is currently operating on the monitoring route. On the side of the in-vehicle terminal device 2, each work vehicle other than the vehicle currently traveling on the observation route is called "other vehicle."

[0050] The map display means 48 reads map information from the map information storage means 44 and displays the map on the display device 40. The tour route selection means 49 selects one tour route from the tour routes stored in the tour route information storage means 45 as a viewing route in accordance with a selection instruction input by an operator from the input device 41. The tour route display means 50 reads the tour route (viewing route) selected by the tour route selection means 49 from the tour route information storage means 45 and displays the selected tour route on the map displayed on the display device 40. The viewing vehicle track display means 51 displays the host vehicle's completed tour track, which is the track that the host vehicle (viewing vehicle) on which the in-vehicle terminal device 2 is mounted, on the map displayed on the display device 10. The other vehicle track acquisition means 52 acquires the other vehicle's completed tour track from the management server 1 in real time and stores it in the other vehicle track information storage means 47. The "already traveled locus of another vehicle" is the already traveled locus of another vehicle patrolling the observation route currently patrolled by the own vehicle on the observation route. The other vehicle locus display means 53 reads out and displays the already traveled locus of another vehicle currently patrolling the observation route currently patrolled by the own vehicle from the other vehicle locus information storage means 47.

[0051] The operation of the patrol work support management system according to the first embodiment configured as described above will be described below. First, the operation of the in-vehicle terminal device 2 related to the support of the work of the worker will be described, and then the operation of the management server 1 related to the support of the work of the commander will be described.

[0052] (1) Operations related to supporting the work of workers on the vehicle-mounted terminal device side 4 is a flowchart of the initial operation of the on-board terminal device 2 for supporting the work of the worker in the patrol work support management system according to the first embodiment. Fig. 4 shows the initial operation from when the on-board terminal device 2 communicates with the management server 1 and acquires the latest patrol route information to when the on-board terminal device 2 moves to the next patrol guidance session. This operation is executed by communication between the on-board terminal device 2 and the management server 1 via the communication line 3.

[0053] In step S001, the on-board terminal device 2 transmits the work vehicle ID of its own vehicle and a tour route information request to the management server 1. In step S011, when the management server 1 receives (the work vehicle ID, tour route information request) from the on-board terminal device 2, it extracts tour route information for all tour routes related to the business operator identified by the work vehicle ID from the tour route information storage means 14 (S012) and transmits the read tour route information to the on-board terminal device 2 (S013). The on-board terminal device 2 stores the received tour route information in the tour route information storage means 45 (S003) and proceeds to the next tour guidance session (FIG. 5) (S004, S014).

[0054] Here, each business operator that performs refuse collection work is assigned one or more patrol routes that the business operator is responsible for, and patrol route information for all businesses is stored in the patrol route information storage means 14. In step S012, one or more patrol routes that are assigned to the business operator identified by the work vehicle ID are extracted from this patrol route information.

[0055] FIG. 5 is a flowchart illustrating the operation of a tour guidance session of the tour work support management system according to the first embodiment.

[0056] First, in the on-board terminal device 2, the tour route selection means 49 displays on the display device 40 a "route selection screen" on which the operator can select a tour route to be traveled by the vehicle from among the tour routes stored in the tour route information storage means 45. The operator operating the on-board terminal device 2 uses the input device 41 to input a selection to select one tour route from the "route selection screen" (S021). When the selection is input, the map display means 48 displays on the display device 40 a map of the area surrounding the current position of the vehicle detected by the positioning device 42, and the tour route selection means 49 reads the selected tour route from the tour route information storage means 45 as a viewing route and displays the selected tour route on the map displayed on the display device 40 (S022). Next, the on-board terminal device 2 transmits to the management server 1 the service vehicle ID of the vehicle, the tour route ID of the selected viewing route, and a tour guidance session start request (S023). When the management server 1 receives (work vehicle ID, tour route ID, tour guidance session start request) from the on-board terminal device 2, it starts a tour guidance session for the tour route specified by the tour route ID of the work vehicle specified by the work vehicle ID (S051). Here, a "session" refers to a series of operations from the start of the exchange of necessary data (data communication) between the two hosts to the end of data communication when communication is performed between a client (on-board terminal device 2) and a server (management server 1) on a computer network.

[0057] Next, the on-board terminal device 2 detects the current position (latitude and longitude) of its own vehicle using the positioning device 42 (S024), and the vehicle position transmission means 43 transmits the position information of the detected vehicle position together with the vehicle ID of the own vehicle to the management server 1 (S025). When the management server 1 receives (vehicle ID, position information) from the on-board terminal device 2 (S052), the vehicle trajectory update means 16 stores the pair (q, t) of the position q indicated by the position information of the work vehicle 4 (observation vehicle) corresponding to the work vehicle ID and the time t when the observation vehicle is at position q as a trajectory point of the traveled trajectory in the vehicle trajectory storage means 15 (S053). As a result, the traveled trajectories of each work vehicle patrolling each patrol route are continuously updated in real time in the vehicle trajectory storage means 15 of the management server 1.

[0058] Next, the other vehicle trajectory acquisition means 21 of the management server 1 reads from the work vehicle trajectory storage means 15 information (other vehicle trajectory information) about the patrolled trajectories (other vehicle trajectories) of other work vehicles (other vehicles) other than the observation vehicle that are currently patrolling the observation route currently patrolled by the observation vehicle that transmitted the position information in step S025, and transmits this information to the on-board terminal device 2 of the observation vehicle (S054). Note that if the subject vehicle is the only work vehicle currently operating on the observation route, the other vehicle trajectory information will be empty information that does not include a single other vehicle trajectory.

[0059] When the other vehicle locus acquisition means 52 of the in-vehicle terminal device 2 receives this other vehicle's traveled locus information from the management server 1, it stores it in the other vehicle locus information storage means 47 (S026). As a result, the other vehicle's traveled loci of other vehicles operating on the observation route are stored in the other vehicle locus information storage means 47 of the in-vehicle terminal device 2, and these are continuously updated in real time. Note that if the other vehicle's traveled locus information received from the management server 1 is null information, the other vehicle locus acquisition means 52 cannot acquire even one other vehicle's traveled locus, and therefore the stored information in the other vehicle locus information storage means 47 is not updated in step S026.

[0060] Next, the map display means 17 of the in-vehicle terminal device 2 reads out from the map information storage means 44 a map sheet of the surrounding area centered on the position of the vehicle detected by the positioning device 42 in step S024, and displays the map on the display device 40 (S027). Next, the tour route display means 50 of the in-vehicle terminal device 2 reads out tour route information of the observation route from the tour route information storage means 45, and displays the observation route on the map displayed on the display device 40 (S028). Next, the observation vehicle track display means 51 of the in-vehicle terminal device 2 reads out the toured track of the vehicle (the vehicle's toured track) from the vehicle track information storage means 46, and displays it on the map displayed on the display device 10. Further, the other vehicle trajectory display means 53 reads out the patrolled trajectories of other vehicles currently traveling on the observation route (the patrolled trajectories of other vehicles) from the other vehicle trajectory information storage means 47, and displays the patrolled trajectories of other vehicles together with icons indicating the current positions of the other vehicles on the map displayed on the display device 10 (S029).Then, the observed vehicle trajectory display means 51 of the in-vehicle terminal device 2 displays the current position of the vehicle detected by the positioning device 42 in step S024 on the map displayed on the display device 10 using a predetermined icon (S030).

[0061] Next, the vehicle-mounted terminal device 2 determines whether or not a work end instruction has been input by the worker from the input device 41, and if a work end instruction has not been input, the process returns to the above-mentioned step S024 and repeats the processes of S024 to S030 (S031). On the other hand, if a work end instruction has been input, the vehicle-mounted terminal device 2 transmits the work vehicle ID of its own vehicle and a request to end the tour guidance session to the management server 1 (S032), and upon receiving this (work vehicle ID, tour guidance session end request), the management server 1 ends the tour guidance session for the work vehicle identified by the work vehicle ID (S055).

[0062] 6A and 6B are diagrams showing examples of map images displayed on the display device 40 of the in-vehicle terminal device 2 in steps S027 to S030. Fig. 6A shows a map display screen when there are no other vehicles on the route (viewing route) currently being traveled by the vehicle, and Fig. 6B shows a map display screen when there are other vehicles on the viewing route. In Figs. 6A and 6B, the viewing route is displayed by a thick solid line in display color C1 (e.g., blue), the track already traveled by the vehicle is displayed by a dotted line in display color C2 (display color C2 is a different color that can be distinguished from display color C1, e.g., red), and the current position of the vehicle is displayed by a double circle icon in display color C2 (note that color is omitted in Fig. 6 because it is a grayscale image that cannot be displayed in color; the same applies below). In addition, in Figure 6(b), the patrolled path of the other vehicle is displayed as a dotted line in display color C3 (display color C3 is a different color that can be distinguished from display colors C1 and C2, for example, green), and the current location of the other vehicle is displayed as a double circle icon in display color C3. Note that the example shown in Figure 6(b) shows a case where the traveling directions of the own vehicle and the other vehicle on the observation route are opposite (the condition is that there are no one-way sections or sections with central dividers on the observation route), but of course there are also cases where the traveling directions of the own vehicle and the other vehicle are the same.

[0063] In Figure 6, each work vehicle travels along a monitoring route, performing door-to-door garbage collection work, collecting garbage placed in front of each house along the monitoring route. When multiple work vehicles are performing patrol work on a single monitoring route, as shown in Figure 6(b), the display device 40 displays the patrol tracks of other vehicles in addition to the patrol track of the vehicle itself. This allows workers to grasp the progress of the patrol work on the monitoring route, including the progress of the work of the other vehicles, as well as the progress of the work of the vehicle itself. This also allows workers to grasp in real time the sections of the monitoring route that have been completed. This prevents redundant patrols of sections already completed by other vehicles, thereby improving work efficiency.

[0064] (2) Operations related to the commander's business support on the management server side Since the commander on the management server 1 side needs to issue appropriate instructions to all operating work vehicles 4, the management server 1 is required to be able to display the operating status of all work vehicles 4 on a map displayed on the display device 10.

[0065] 7 is a flowchart of the operation related to the support of a commander's work on the management server 1 side of the patrol work support management system according to Example 1. The management server 1 displays a map read from the map information storage means 13 on the display device 10 by the map display means 17, and on the map an icon of the current position of each work vehicle and the patrolled path of the work vehicle are displayed by the work vehicle selection means 18. In addition, the information on the patrolled path of each work vehicle stored in the work vehicle path storage means 15 is continuously updated in real time by the work vehicle path update means 16.

[0066] First, in step S061, the commander operating the management server 1 selects the icon of the current position of the work vehicle to be observed from the icons of the current positions of the work vehicles displayed on the map, using the input device 11. The work vehicle selection means 18 sets the selected work vehicle as the observation vehicle.

[0067] Next, in step S062, the tour route display means 19 reads out tour route information for the tour route (observation route) that the observation vehicle is currently patrolling from the tour route information storage means 14. Also, the observation vehicle track display means 20 reads out the toured track of the observation vehicle (observation vehicle toured track) from the work vehicle track storage means 15, and acquires the current position of the observation vehicle.

[0068] Next, in step S063, the map display means 17 displays on the display device 10 a map sheet of the area surrounding the current observation car position that has been acquired.

[0069] Next, in step S064, the tour route display means 19 of the management server 1 displays the tour route information of the viewing route read from the tour route information storage means 14 on the map displayed on the display device 40.

[0070] Next, in step S065, the observation vehicle trajectory display means 20 of the management server 1 reads out the observation vehicle's completed patrol trajectory (observation vehicle's completed patrol trajectory) from the work vehicle trajectory storage means 15 and displays it on the map displayed on the display device 10.

[0071] Next, in step S066, the other vehicle trajectory acquisition means 21 of the management server 1 extracts information on the patrolled trajectories (other vehicle trajectories) of other vehicles patrolling the observation route currently patrolled by the observation vehicle from the work vehicle trajectory storage means 15. Here, the information on the patrolled trajectories of each work vehicle stored in the work vehicle trajectory storage means 15 is continuously updated in real time by the work vehicle trajectory update means 16, so that information on the patrolled trajectories of other vehicles is acquired in real time. Next, in step S067, the other vehicle trajectory display means 22 of the management server 1 displays the patrolled trajectories of other vehicles acquired by the other vehicle trajectory acquisition means 21 on the map displayed on the display device 10 so that they can be distinguished from the patrolled trajectories of the observation vehicle, for example, by using a different color from the patrolled trajectory of the observation vehicle previously displayed. In this case, the screen display of the display device 10 may appear, for example, as shown in FIG. 6(b) described above.

[0072] If there are no other vehicles traveling along the viewing route, no information on the already traveled trajectories of other vehicles is extracted in step S066, and the process of step S067 is omitted. In this case, the screen display of the display device 10 will be, for example, as shown in FIG. 6(a) described above.

[0073] Next, in step S068, the management server 1 determines whether or not an instruction to end the display of the observation vehicles has been input from the input device 11 by the commander, and if the instruction to end the display has not been input, the process returns to step S062 described above and repeats the observation route display process of S062 to S067. On the other hand, if an instruction to end the display has been input, the management server 1 leaves the observation route display process and causes the map display means 17 to display on the display device 10 a map read from the map information storage means 13, and on the map, the work vehicle selection means 18 displays an icon of the current position of each work vehicle in the map display area and the locus that the work vehicle has already traveled, and the process ends.

[0074] In this way, when a plurality of work vehicles are performing patrol work on the observation route patrolled by a selected observation vehicle, by displaying on the display device 10 the patrol tracks of other vehicles patrolling the same route in addition to the patrol track of the observation vehicle, the commander of the management server 1 can grasp the overall progress of the patrol work on the observation route, including the work progress of the other vehicles, and can grasp in real time the sections on the patrol route where patrol work has been completed. In this way, the commander can issue instructions to each work vehicle so that they do not patrol sections where patrol work has already been completed, thereby preventing the occurrence of unnecessary operational work and improving overall work efficiency.

[0075] In this embodiment, an example of applying the present invention to door-to-door garbage collection work has been described, but the present invention is not limited to garbage collection work, and can also be applied to delivery work of letters, packages or goods, and patrol work such as road cleaning work. [Example]

[0076] In the second embodiment, a travel work support management system that can display a predicted progress trajectory and a work start point will be described. In this embodiment, the overall configuration of the travel work support management system is the same as that shown in FIG.

[0077] 8 is a block diagram showing the functional configuration of the management server 1 in the patrol work support management system according to the second embodiment of the present invention. In FIG. 8, components similar to those in FIG. 2 of the first embodiment are given the same reference numerals, and descriptions thereof will be omitted. In the management server 1 of this embodiment, compared to the first embodiment, a travel speed estimation means 30, an observation vehicle progress estimation means 31, another vehicle progress estimation means 32, an observation vehicle predicted progress trajectory display means 33, another vehicle predicted progress trajectory display means 34, a work participating vehicle selection means 35, a work start point determination means 36, and a work start point display means 37 are newly added.

[0078] The operating speed estimation means 30 calculates the estimated operating speed at each point on each patrol route based on the patrol trajectory of each work vehicle 4 stored in the work vehicle trajectory storage means 15. "Estimated operating speed" refers to the operating speed when the work vehicle 4 operates at each point on the patrol route or the required time from the previous point.

[0079] Here, "each point on the tour route" refers to the endpoints of each subsection when the tour route is divided into smaller subsections from the start point to the end point. Figure 9 shows an example of dividing a tour route into subsections. For example, assume a tour route as shown in Figure 9(a). When dividing this tour route into subsections, it is divided at each intersection or turning point on the tour route, as shown in Figure 9(b). Furthermore, if a subsection divided at an intersection or turning point has a length of d or more, it is further divided into subsections of length d or less. In this way, when the tour route is divided into smaller subsections from the start point to the end point, the endpoints (start point and end point) of each subsection are defined as "each point on the tour route" (see Figure 9(c)). Furthermore, "required time from the previous point" refers to the required time from the start point to the end point of a certain subsection when the tour route from the start point to the end point is divided into the above-mentioned subsections and "each point on the tour route" is set. Strictly speaking, the "required time from the previous point" is time and not speed, but since this time is proportional to the speed of the partial section and essentially indicates speed, in this specification, the "required time from the previous point" will also be collectively referred to as the "estimated operating speed."

[0080] Furthermore, when the operating speed estimation means 30 calculates the estimated operating speed at each point on the patrol route, it simply reads out the past patrol trajectories of each work vehicle 4 on that patrol route stored in the work vehicle trajectory storage means 15 and calculates the average operating speed (or the time required from the previous point). Furthermore, if the average operating speed (or the time required from the previous point) varies depending on the day of the week, it is sufficient to calculate the average value for each day of the week.

[0081] The observation vehicle progress estimation means 31 calculates the predicted observation vehicle progress trajectory based on the estimated travel speed at each point on the patrol route (observation route) on which the observation vehicle is traveling. The "predicted observation vehicle progress trajectory" refers to the trajectory that the observation vehicle will follow on the observation route within a predetermined time T from its current position. The "predetermined time T" can be set arbitrarily by the commander using the input device 11. For example, if the predetermined time T is set to 10 minutes, the trajectory that the observation vehicle will follow on the observation route in 10 minutes from its current position will be the "predicted observation vehicle progress trajectory." Hereinafter, this "predetermined time T" will be referred to as the "predicted time."

[0082] The other vehicle progress estimation means 32 calculates the predicted progress trajectory of each other vehicle other than the observation vehicle currently traveling on the observation route based on the estimated traveling speed at each point on the observation route along which the observation vehicle is traveling. The "predicted progress trajectory of other vehicles" refers to the trajectory that a vehicle other than the observation vehicle currently traveling on the observation route will take on the tour route within a predetermined time T from its current position. Here, the "predicted time T" (predicted time) is the same as in the case of the predicted progress trajectory of the observation vehicle. The predicted time T here can also be set arbitrarily by the worker by sending a request to the management server 1 via a communication line using the input device 41 of the on-board terminal device 2.

[0083] The observation vehicle predicted progress trajectory display means 33 displays the observation vehicle predicted progress trajectory on the map displayed on the display device 10 of the management server 1. In addition, the other vehicle predicted progress trajectory display means 34 displays the other vehicle predicted progress trajectory on the map displayed on the display device 10 of the management server 1.

[0084] The work participation vehicle selection means 35 selects a work vehicle to participate in patrol work on the observation route along which the observation vehicle is patrolling, in accordance with instructions input from the commander via the input device 11. The work vehicle selected here is called a "participation requested vehicle." Furthermore, a request to a specific work vehicle to participate (support) in patrol work on a specific patrol route is called a "work participation request." A work participation request is a request made by the commander to a worker in a participation requested vehicle.

[0085] When a participating vehicle is selected by the participating vehicle selection means 35, the operation start point determination means 36 determines the operation start point of the participation requesting vehicle on the patrol route related to the operation participation request. Furthermore, when the operation participation application described below is received from the on-board terminal device 2, the operation start point determination means 36 determines the operation start point of the participation requesting vehicle on the patrol route related to the operation participation request (hereinafter referred to as the "application route") for the work vehicle 4 (hereinafter referred to as the "participation requesting vehicle") related to the on-board terminal device 2 that sent the operation participation application, and transmits information about the operation start point to the on-board terminal device 2 of the participation requesting vehicle. Here, a request by a specific work vehicle to participate (support) in a patrol operation on a specific patrol route is called a "operation participation application." A operation participation application is a request made to the commander (or management server 1) by the worker of the participation requesting vehicle who made the operation participation application. The "operation start point" refers to the point where the participation requesting vehicle or the participation requesting vehicle starts patrol operation on the patrol route related to the operation participation request or the operation participation application. .

[0086] The business start point display means 37 displays the business start point on the map displayed on the display device 10 of the management server 1.

[0087] Fig. 10 is a block diagram showing the functional configuration of the in-vehicle terminal device 2 in the patrol work support management system according to the second embodiment of the present invention. In Fig. 9, components similar to those in Fig. 3 of the first embodiment are given the same reference numerals and their description will be omitted. In the management server 1 of this embodiment, compared to the first embodiment, a viewing vehicle predicted progress trajectory display means 60, another vehicle predicted progress trajectory display means 61, a work participation application sending means 62, and a work start point display means 63 are newly added.

[0088] When the observation vehicle predicted progress trajectory display means 60 receives the information on the above-mentioned predicted progress trajectory of the observation vehicle from the management server 1, it displays the observed vehicle predicted progress trajectory on the map displayed on the display device 40 of the in-vehicle terminal device 2. When the other vehicle predicted progress trajectory display means 61 receives the information on the above-mentioned predicted progress trajectory of the other vehicle from the management server 1, it displays the other vehicle predicted progress trajectory on the map displayed on the display device 40 of the in-vehicle terminal device 2.

[0089] The work participation application sending means 62 sends a work participation application requesting participation in a patrol work of a specific patrol route to the management server 1 in accordance with instructions input from the input device 41 by the worker operating the in-vehicle terminal device 2. When the work start point display means 63 receives information on the work start point sent from the management server 1 in response to the work participation application, it displays the work start point on the map displayed on the display device 40 of the in-vehicle terminal device 2.

[0090] The operation of the thus configured mobile work support management system according to the second embodiment will be described below.

[0091] (1) Operations related to supporting the work of workers on the vehicle-mounted terminal device side Fig. 11 is a flowchart of the operation of a tour guidance session related to the support of work by a worker on the in-vehicle terminal device 2 side in the tour work support management system according to the second embodiment. Note that the initial operation is the same as that in Fig. 4 of the first embodiment, and therefore a description thereof will be omitted. In Fig. 11, the same operational steps as those in Fig. 5 of the first embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

[0092] In this embodiment, in step S025, (work vehicle ID, location information) is sent from the vehicle-mounted terminal device 2 to the management server 1, and after the management server 1 receives this (S052), the work vehicle trajectory update means 16 stores this as a trajectory point of the patrolled trajectory in the work vehicle trajectory storage means 15 (S053). Here, the work vehicle that sent the location information identified by the work vehicle ID is referred to as the "observation vehicle," and the patrol route currently being traveled by this observation vehicle is referred to as the "observation route."

[0093] Next, in step S053_1, the travel speed estimation means 30 of the management server 1 calculates an estimated travel speed at each point on the observation route based on information about the patrolled trajectories of each work vehicle 4 that has previously traveled the observation route, which is stored in the work vehicle trajectory storage means 15. Then, the observation vehicle progress estimation means 31 of the management server 1 uses the calculated estimated travel speed to calculate the observation vehicle's predicted progress trajectory for the observation vehicle. At this time, the predicted time T of the observation vehicle's predicted progress trajectory is assumed to be set in advance.

[0094] Furthermore, with regard to the estimated operating speed at each point on the observation route, when the management server 1 receives a session start request in step S051, the operating speed estimation means 30 may calculate the estimated operating speed at each point on the observation route in advance, store it in the memory of the management server 1, and use this stored estimated operating speed.

[0095] Next, in step S053_2, the other vehicle trajectory acquisition means 21 of the management server 1 reads out information (other vehicle trajectory information) about the patrolled trajectories (other vehicle patrolled trajectories) of other work vehicles (other vehicles) other than the observation vehicle that are currently patrolling the observation route on which the observation vehicle is currently patrolling, which have traveled on the observation route.

[0096] Next, in step S053_3, the other vehicle predicted travel locus display means 34 of the management server 1 calculates the other vehicle predicted travel locus for each other vehicle other than the observation vehicle currently traveling on the observation route, using the estimated travel speed at each point on the observation route on which the observation vehicle is traveling. If there are no other vehicles, this step is omitted.

[0097] Then, in step S054, the management server 1 transmits the other vehicle's already-patrolled trajectory information, as well as the observation vehicle's predicted progress trajectory information and the other vehicle's predicted progress trajectory information, to the observation vehicle's in-vehicle terminal device 2. Note that if the own vehicle is the only work vehicle currently operating on the observation route, the other vehicle's already-patrolled trajectory information and the other vehicle's predicted progress trajectory information will be null information that does not include one other vehicle's already-patrolled trajectory or other vehicle's predicted progress trajectory information.

[0098] Next, in step S026, when the other vehicle trajectory acquisition means 52 of the in-vehicle terminal device 2 receives the other vehicle's completed trajectory information, the observation vehicle's predicted progress trajectory information, and the other vehicle's predicted progress trajectory information from the management server 1, it stores these in the other vehicle trajectory information storage means 47.

[0099] Next, as in the first embodiment, in step S027, the map display means 17 of the in-vehicle terminal device 2 displays a map on the display device 40, in step S028, the tour route display means 50 of the in-vehicle terminal device 2 displays the tour route on the map displayed on the display device 40, and in step S029, the toured vehicle trajectory display means 51 and the other vehicle trajectory display means 53 of the in-vehicle terminal device 2 display the host vehicle's toured trajectory and the other vehicle's toured trajectory on the map displayed on the display device 40.

[0100] Next, in step S029_1, the observation vehicle predicted progress trajectory display means 60 of the in-vehicle terminal device 2 displays, on the map displayed on the display device 40, the observation vehicle predicted progress trajectory (host vehicle predicted progress trajectory), which is the predicted trajectory along which the host vehicle will proceed on the observation route at a predetermined predicted time T, based on the observation vehicle predicted progress trajectory information received in step S026. Also, the other vehicle predicted progress trajectory display means 61 of the in-vehicle terminal device 2 displays, on the map displayed on the display device 40, the other vehicle predicted progress trajectory, which is the predicted trajectory along which the other vehicle will proceed on the observation route at a predetermined predicted time T, based on the other vehicle predicted progress trajectory information received in step S026.

[0101] Next, in step S030, the observation vehicle track display means 51 of the in-vehicle terminal device 2 displays the current position of the vehicle detected by the positioning device 42 in step S024 on the map displayed on the display device 40 using a predetermined icon.

[0102] In this way, in the patrol work support management system of this embodiment, in addition to the patrol path of the subject vehicle and the patrol path of the other vehicle, the predicted travel path of the observed vehicle (predicted travel path of the subject vehicle) and the predicted travel path of the other vehicle are also displayed on the observation route. Figure 12 is a diagram showing an example of a map image displayed on the display device 40 of the in-vehicle terminal device 2 in steps S027 to S030 of the second embodiment. In Figure 12, as in Figure 6(b), the observation route is displayed by a thick solid line in display color C1 (e.g., blue), the vehicle's patrolled path is displayed by a dotted line in display color C2 (display color C2 is a different color that can be distinguished from display color C1; e.g., red), the vehicle's current position is displayed by a double circle icon in display color C2, the other vehicle's patrolled path is displayed by a dotted line in display color C3 (display color C3 is a different color that can be distinguished from display colors C1 and C2; e.g., green), and the other vehicle's current position is displayed by a double circle icon in display color C3 (note that color is omitted in Figure 12 because it is a grayscale image that cannot display color; the same applies below). Furthermore, the observed vehicle's predicted travel trajectory (host vehicle's predicted travel trajectory) is displayed as a thick solid line in display color C2' (display color C2' is a different color that can be distinguished from display colors C1, C2, and C3, for example, pink), and the other vehicle's predicted travel trajectory is displayed as a thick solid line in display color C3' (display color C3' is a different color that can be distinguished from display colors C1, C2, C2', and C3, for example, yellow-green). Note that the example shown in Figure 12 shows a case where the host vehicle and other vehicles on the observation route are traveling in opposite directions, but of course there are also cases where the host vehicle and other vehicles are traveling in the same direction.

[0103] 12, when patrolling a single inspection route is performed by multiple work vehicles, by displaying the patrolled locus of other vehicles in addition to the patrolled locus of the own vehicle on the display device 40, the worker can grasp the progress of the patrol work on the inspection route, including the work progress of not only the own vehicle but also the other vehicles, and can grasp in real time the sections on the inspection route where patrol work has been completed. This prevents redundant patrols of sections where patrol work has already been completed by other vehicles, and improves work efficiency. Furthermore, by displaying the predicted progress trajectory of the observation vehicle (predicted progress trajectory of the subject vehicle) as it moves along the observation route from its current position within a specified time, and the predicted progress trajectory of other vehicles operating on the same observation route as it moves along the patrol route from its current position within a specified time, workers on board the observation vehicle can visually grasp how much progress will be made in the patrol work on this observation route within the specified time T, making it easier to decide whether to request additional support vehicles to share in the patrol work on the observation route.

[0104] (2) Operations related to the commander's business support on the management server side Fig. 13 is a flowchart of the operation related to the support of the commander's work on the management server 1 side in the patrol work support management system according to the embodiment 2. In Fig. 13, the same operational steps as those in Fig. 7 of the embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted.

[0105] In this embodiment, after an observation vehicle is selected in step S061, in step S061_1, the traveling speed estimation means 30 of the management server 1 calculates an estimated traveling speed at each point on the observation route (the patrol route on which the observation vehicle is currently traveling) based on information on the patrol trajectories of each work vehicle 4 that has previously traveled the observation route (the patrol route on which the observation vehicle is currently traveling), which is stored in the work vehicle trajectory storage means 15. The calculated estimated traveling speeds at each point are stored in the memory of the management server 1.

[0106] Furthermore, in step S067, after the other vehicle trajectory display means 22 of the management server 1 displays the patrolled trajectory of the other vehicle on the map displayed on the display device 10, in step S067_1 the observation vehicle progress estimation means 31 of the management server 1 calculates the observation vehicle's predicted progress trajectory for the observation vehicle using the estimated traveling speed calculated previously. Also, the other vehicle predicted progress trajectory display means 34 of the management server 1 calculates the predicted progress trajectories of other vehicles other than the observation vehicle currently traveling on the observation route using the estimated traveling speed at each point on the observation route on which the above-mentioned observation vehicle is traveling. At this time, the predicted time T of the observation vehicle's predicted progress trajectory and the other vehicle's predicted progress trajectory is assumed to be set in advance.

[0107] Then, in step S067_2, the observation vehicle predicted progress trajectory display means 33 of the management server 1 displays, on the map displayed on the display device 10 of the management server 1, the observation vehicle predicted progress trajectory, which is the predicted trajectory along which the host vehicle will proceed on the observation route at a predetermined predicted time T, based on the observation vehicle predicted progress trajectory information. Also, the other vehicle predicted progress trajectory display means 34 of the management server 1 displays, on the map displayed on the display device 10 of the management server 1, the other vehicle predicted progress trajectory, which is the predicted trajectory along which the other vehicle will proceed on the observation route at a predetermined predicted time T, based on the other vehicle predicted progress trajectory information. As a result, the display image displayed on the display device 10 of the management server 1 is similar to that shown in FIG.

[0108] In this way, by displaying on the display device 10 of the management server 1 the predicted movement trajectory of the observation vehicle selected by the commander and the predicted movement trajectories of other vehicles operating on the same patrol route as the observation vehicle, the commander can visually grasp how much progress will be made in the patrol work within a specified time period, making it easier for him to decide whether or not to request the dispatch of a support vehicle to share the patrol work on that patrol route.

[0109] (3) Request for participation in work from the work vehicle to the management server Next, we will explain the operation of the patrol work support management system when a work vehicle is already operating on a patrol route and another work vehicle is newly joining the patrol work on that route.

[0110] FIG. 14 is a flowchart showing the operation of the patrol work support management system when a work vehicle newly joins a patrol work on a patrol route.

[0111] First, in step S070, a worker operating the on-board terminal device 2 of the work vehicle 4 (hereinafter referred to as the "participation applying vehicle") inputs a selection instruction from the input device 41 of the on-board terminal device 2 to select the patrol route in which the participation applying vehicle will participate in the work.

[0112] Next, in step S071, the business participation application sending means 62 of the vehicle-mounted terminal device 2 sends a business participation application, which requests the application vehicle to participate in the patrol business of the input patrol route (hereinafter referred to as the "application route"), together with the work vehicle ID of the application vehicle and the patrol route ID of the application route, to the management server 1. In step S080, the management server 1 receives (business participation application, work vehicle ID, patrol route ID) from the vehicle-mounted terminal device 2.

[0113] Next, in step S081, the operating speed estimation means 30 of the management server 1 calculates the estimated operating speed at each point on the applied route identified by the route ID received along with the business participation application, based on the completed patrol trajectories of each work vehicle 4 stored in the work vehicle trajectory storage means 15.

[0114] Next, in step S082, the operation start point determination means 36 of the management server 1 determines the operation start point of the application route for the participating vehicle. Here, if there is no work vehicle currently traveling on the application route, the operation start point determination means 36 determines the start point of the application route as the operation start point. Furthermore, if there is a work vehicle currently traveling on the application route (hereinafter referred to as the "existing participant vehicle"), the operation start point determination means 36 determines the operation start point (recommended entry point) based on the estimated operating speed at each point on the application route so as to minimize the sum (T1 + T2) of the estimated travel time T1 for the existing participant vehicle to travel on the application route from the current point and the estimated travel time T2 for the participation applicant vehicle to reach the operation start point from its current position and then travel on the application route (however, the section on the application route traveled by the existing participant vehicle and the section on the application route traveled by the participation applicant vehicle do not overlap). This is explained for clarity using FIG. 15. In FIG. 14, the start point of the applied route is q0, the end point is q1, the current position of the already participating vehicle on the applied route is q2, the current position of the participation applying vehicle is q3, and the operation start point (recommended entry point) is q4. The estimated travel time T1 for the already participating vehicle to travel along the applied route from the current position q2 of the already participating vehicle is the estimated time it takes for the already participating vehicle to travel from the current position q2 to the operation start point q4. Furthermore, if the estimated time for the participation applying vehicle to travel from the current position q3 to the operation start point q4 is T2a, and the estimated time for the participation applying vehicle to travel from the operation start point q4 to the end point q1 of the applied route is T2a + T2b, the estimated travel time T2 for the participation applying vehicle is T2a + T2b. The operation start point determination means 36 determines the position q4 of the operation start point so that the sum (T1 + T2) is minimized. Here, the estimated time T2a for the participating vehicle to arrive at the operation start point q4 from the current position q3 can be calculated based on the road information included in the map information, just like in a normal car navigation system. The estimated times T1 and T2b can be calculated based on the road information of the applied route included in the map information and the estimated driving speed at each point on the applied route.

[0115] Next, in step S083, the business start point determination means 36 of the management server 1 transmits location information of the determined business start point (recommended entry point) to the in-vehicle terminal device 2 of the participation applying vehicle. In step S072, the in-vehicle terminal device 2 of the participation applying vehicle receives the location information of the business start point (recommended entry point). Then, in step S073, the business start point display means 63 displays the business start point on the map displayed on the display device 40 of the in-vehicle terminal device 2, and also displays a guide route to the business start point of the participation applying vehicle.

[0116] Fig. 16 is a diagram showing an example of a map image showing a work start point displayed on the display device 40 of the in-vehicle terminal device 2. In Fig. 16, the work start point (recommended entry point) is indicated by a pin mark on the tour route. Also, the entry direction in which the work vehicle that has applied to participate will enter the tour route from the work start point is indicated by an arrow.

[0117] (4) A request from the management server to the work vehicle to participate in the work FIG. 17 is a flowchart showing the operation of the patrol work support management system when the commander of the management server issues a new work request to a specific work vehicle for patrol work on a patrol route.

[0118] First, in step S090, the management server 1 displays a map on the display device 10. Next, in step S091, the management server 1 selects one tour route as a monitoring route, and in step S092, the tour route display means 19 of the management server 1 displays the selected tour route on the map displayed on the display device 10. Next, in step S093, the other vehicle trajectory acquisition means 21 of the management server 1 reads out information on the toured trajectory (the toured trajectory of the previously participating vehicle) of the work vehicle 4 currently traveling on the monitoring route (hereinafter referred to as the "previously participating vehicle") from the work vehicle trajectory storage means 15, and the other vehicle trajectory display means 22 displays the read toured trajectory of the previously participating vehicle on the map displayed on the display device 10.

[0119] Next, in step S094, the operation participating vehicle selection means 35 of the management server 1 According to input from the commander, a work vehicle other than a vehicle already participating in the observation route (hereinafter referred to as a "participation requested vehicle") is selected to be requested to participate in the patrol work on the observation route.

[0120] Next, in step S095, the operating speed estimation means 30 of the management server 1 calculates the estimated operating speed at each point on the observation route based on the patrolled trajectories of each work vehicle 4 stored in the work vehicle trajectory storage means 15.

[0121] Next, in step S096, the business start point determination means 36 of the management server 1 determines a business start point (recommended entry point) of the participation requested vehicle on the applied route. The method for determining the business start point is the same as the method described above with reference to FIG.

[0122] Next, in step S097, the task start point display means 37 of the management server 1 displays the task start point on the map displayed on the display device 10 of the management server 1. The commander of the management server 1 can recognize the task start point of the participation requested vehicle by looking at this display.

[0123] Next, in step S097, the management server 1 transmits the business participation request together with the tour route ID of the observation route and the business start point (recommended entry point) information to the in-vehicle terminal device 2 of the participation requesting vehicle. Then, in step S110, the in-vehicle terminal device 2 of the participation requesting vehicle receives (business participation request, tour route ID, business start point).

[0124] Next, in step S111, the map display means 48 of the in-vehicle terminal device 2 displays a map of the area around the business start point on the display device 40, in step S112 the tour route display means 50 of the in-vehicle terminal device 2 displays the viewing route specified by the tour route ID on the map displayed on the display device 40, and in step S113 the business start point display means 63 of the in-vehicle terminal device 2 displays the business start point on the map displayed on the display device 40. The display on the screen at this time is similar to the display shown in FIG.

[0125] In this way, when there is a participating vehicle already patrolling a certain route and the commander requests a participation request vehicle to participate in support for the patrol work on that route, the commander can instruct the start point of the work so that the sum of the time required for the patrol work that the already participating vehicle will perform and the time required for the patrol work that the participation request vehicle will perform can be minimized, making it possible to carry out the entire patrol work efficiently.

[0126] In this embodiment, an example of applying the present invention to door-to-door garbage collection work has been described, but the present invention is not limited to garbage collection work, and can also be applied to delivery work of letters, packages or goods, and patrol work such as road cleaning work.
