Abstract

To provide a patrol task support and management system that can reduce burden on a commander that issues commands to operation vehicles that performs patrol tasks on a patrol route, and enables effective operations of the operation vehicles.SOLUTION: A management server stores, as a patrolled locus, position information that is sequentially received from an on-vehicle terminal on each of operation vehicles that perform patrol tasks. 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 a patrol work in which the work vehicle travels along a predetermined patrol route and performs a predetermined task. [Background technology]

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

[0003] Patent Document 1 describes a patrol work support management system for refuse collection work. This system includes a management server and a worker terminal device. The worker terminal device acquires a list of refuse stations (STs) on a refuse collection route from the management server, displays a map on a touch panel display (TD), and displays each ST position on the map with a mark "●" based on each ST information in the ST list. In addition, the ST information included in the ST list is displayed as a list on the side of the map on the TD screen. Then, a worker selects one ST by touching the ST information included in the ST list, and an ST photo and guide information related to the selected ST are displayed on the TD or output from a speaker. This makes it easier to grasp the location of STs whose locations are difficult to understand, and even when a worker is in charge of the route for the first time, he or she can reliably perform collection work at each ST. As a result, a high level of refuse collection service is homogenized regardless of the worker's personal skill level and 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 Figs. 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, 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's movement on pre-prepared 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 position, reverse section, stop position, and stop direction on the trajectory, and generates vehicle trajectory information by adding the additional information to the trajectory. The in-vehicle device (30) displays map information in the vicinity of the current location on the display device (see FIG. 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 the collected position 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. Also, 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 new driver to drive as efficiently as a veteran driver.

[0005] Patent Document 3 describes a mobile work support management system (waste collection support system) for refuse collection work. 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 them (see Figure 1 of the document). The server (10) includes a waste collection determination unit (21a) that determines whether each collection station (scheduled collection site) is a collection completed point or an 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 in the navigation device 100 via a communication line. A map is drawn on the display of the navigation device (100), and icons of collection stations 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 when the distance between the current location of the collection vehicle and a collection station is within a predetermined distance, it considers that collection of waste at the collection station is completed. The display control unit (21b) displays a map on the display at a scale based on the collection stations where collection is incomplete (a scale where the number of collection incomplete points is at least equal to or greater than the set number of points). This can prevent the collector from having to check the collection station where collection is incomplete every time collection is performed. In addition, when collection of waste is completed at the collection station where collection is incomplete, the color of the icon of the collection station is changed, or the display of the collection station is erased. This allows the collector to easily determine whether the collection station displayed on the display is a collection completed point or an incomplete collection point.

[0006] [Patent Document 1] JP 2020-129374 A [Patent Document 2] JP 2008-071072 A [Patent Document 3] JP 2023-109373 A [Patent Document 4] JP 2021-156581 A [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 patrol service, can be roughly 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 the discharge and collection of general waste (household garbage)) and the garbage is collected by a collection company. "Door-to-door collection" refers to a system in which garbage is placed 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 above are all systems that support or manage the 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 the purpose of collecting garbage and transporting it to a disposal facility) travels along a predetermined route and collects garbage placed in front of each house or business along the route (within the premises of the home or business facing the road). In this case, too, a navigation system is used to guide the patrol route (see Patent Document 4).

[0010] In actual work sites, in order to reduce the overall work time, a single door-to-door collection route may be covered by multiple garbage trucks. In such cases, the command center that instructs each garbage truck to operate the same door-to-door collection route issues instructions on which points and sections each truck should cover.

[0011] However, when there are many refuse trucks operating at the same time, it is a lot of work for the command center to issue instructions to each refuse truck regarding the starting point of the patrol and the patrol section, which places a heavy burden on the command center's commander (the person who issues instructions to each refuse truck). In addition, it is easy for command errors to occur, such as accidentally instructing the same truck to cover a section that has already been collected. The above-mentioned conventional patrol work support management system is insufficient to deal with such 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 a commander who issues commands to each work vehicle when multiple work vehicles patrol a single patrol route to perform patrol work, 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 a predetermined task, A management server; a vehicle-mounted terminal device that is mounted on each of the work vehicles and has a positioning device for measuring a 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 includes: a work vehicle information storage means for storing information on each of the work vehicles, the work vehicle information including information on a route that the work vehicle is currently traveling; A work vehicle track storage means for storing the completed patrol tracks of each of the work vehicles; a work vehicle trajectory update means for receiving position information of each work vehicle transmitted from the vehicle-mounted 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 in the work vehicle trajectory storage means as a completed patrol trajectory; Equipped with The management server or the in-vehicle terminal device A display device; A map information storage means for storing map information; a route information storage means for storing information on the route; a map display means for displaying a map on the display device; a route display means for reading out the route from the route information storage means and displaying the route on the map displayed on the display device; a viewing vehicle track display means for displaying a viewing vehicle completed track, which is a track completed by a certain one of the work vehicles (hereinafter referred to as "viewing vehicle"), on a map displayed on the display device; an other vehicle trajectory acquisition means for acquiring a other vehicle trajectory, which is a trajectory of a work vehicle (hereinafter referred to as "other vehicle") other than the observation vehicle that patrols the patrol route on which the observation vehicle is currently patrolling, on the patrol route; a vehicle trajectory display means for displaying the vehicle trajectory acquired by the vehicle trajectory acquisition means on a map displayed on the display device so as to be distinguishable from the observation vehicle trajectory; The present invention is characterized by comprising:

[0014] According to this configuration, when a single patrol route is performed by a plurality of work vehicles, the display device displays the patrol route of other vehicles in addition to the patrol route of the observation vehicle, thereby making it possible to grasp the progress of the patrol route including the work progress of the observation vehicle as well as other vehicles, and to grasp in real time the sections on the patrol route where the patrol route has been completed. This makes it possible to prevent redundant patrols of sections where the patrol route 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 a designated task or work, including garbage collection, delivery of letters, packages, or goods, and road cleaning. "Traveling route" refers to the route traveled around each location to perform a designated task. "Loading" refers to loading an on-board terminal device onto a work vehicle or installing an on-board terminal device onto a work vehicle, and includes the case where a worker carrying an on-board terminal device is riding on the work vehicle while carrying the on-board terminal device. "Positioning device" refers to a device that determines the position of a moving object, and includes the Global Navigation Satellite System (GNSS), which performs positioning using a satellite positioning system, and base station positioning using base station positioning (which calculates the distance from the telecommunications carrier's base station to the mobile terminal and determines the terminal's position).

[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 when the work vehicle is at that position" referred to here may be the time when the position information is detected by the positioning device and transmitted to the management server by the vehicle position transmission means, and the time included in the position information may be regarded as the "time when the vehicle is at that position", or the time when the management server receives the position information transmitted from the vehicle-mounted terminal device may be regarded as the "time when the vehicle is at that position". This is because, in general, it is considered that the time lag between when the position information is detected by the positioning device, when that position information is transmitted to the management server, and when that position information is received by the management server is small.

[0017] A second configuration of the mobile work support management system according to the present invention is the first configuration, further comprising: 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 track display means acquires a current position detected by the positioning device at each time, and displays a completed tour track 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, a trajectory of another vehicle that is a trajectory of the other vehicle traveling on the patrol route on which the observation vehicle is currently traveling. It is characterized by:

[0018] According to this configuration, when patrol work on one patrol route is performed by multiple work vehicles, a worker in an observation vehicle (in this case, the observation vehicle refers to the worker's own vehicle (a 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 as well as the patrol work completed by other vehicles, and can 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 within a specified time from its current position is displayed, allowing workers aboard the observation vehicle to visually grasp how much progress will be made on the patrol work within a specified time, making it easier to decide whether or not to request a support vehicle to share the patrol work on that patrol route.

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

It is characterized by:

[0025] According to this configuration, when there is a participating vehicle already patrolling a certain route and the vehicle applying to participate joins in to support the patrol work on that route, the start point of the work is instructed 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 vehicle applying to participate will perform is minimized, making it possible to carry out the entire patrol work efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. EXAMPLES

[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 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 showing the overall configuration of a patrol work support management system according to a first embodiment of the present invention. The patrol 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 mounted on a work vehicle 4 that performs patrol work. The "route work" here refers to a garbage collection work by 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 on 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 who rides on the work vehicle 4, such as a tablet or a 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 is also equipped with a positioning device 42, such as a GNSS (Global Navigation Satellite System), as described later. Furthermore, the management server 1 is operated by a commander who issues various work instructions to each work vehicle 4, and the vehicle 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] Fig. 2 is a block diagram showing the functional configuration of the management server 1 of Fig. 1. In Fig. 2, the management server 1 comprises, as its hardware configuration, a display device 10 and an input device 11. In addition, as its functional configuration, it comprises a work vehicle information storage means 12, a map information storage means 13, a tour route information storage means 14, a work vehicle track storage means 15, a work vehicle track update means 16, a map display means 17, a work vehicle selection means 18, a tour route display means 19, a viewing vehicle track display means 20, another vehicle track acquisition means 21, and another vehicle track display means 22. Each of these functional components is configured as a functional module in 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 travel route that the work vehicle is currently traveling. The "travel route" here refers to the route that travels around each location where food waste collection is performed in order to perform food waste collection work. The map information storage means 13 stores information about a map (map information). "Map information" includes information about roads, buildings and landmarks, and the information about roads includes information about the number of lanes, the presence or absence of a median strip, road width, speed limit, one-way streets, etc. The travel route information storage means 14 stores information about each travel route (travel route information). The travel route information includes identification information (travel route ID) of the travel route, information about the tracks (roads, paths, other passages) that the travel route passes through, and information about the business operator in charge of the travel 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 traveled when it 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 vehicle-mounted 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 position q in the vehicle trajectory storage means 15 as a trajectory point of the already-patrolled trajectory. The position q=(x, y) is a latitude and longitude coordinate (coordinates of longitude x and latitude y). The already-patrolled trajectory stored in the vehicle trajectory update means 16 is made up 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 work vehicle 4 transmitted 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 work vehicle 4 is at its position q". If the position information of the work vehicle 4 transmitted 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 work vehicle 4 is at its position q".

[0045] The map display means 17 reads out 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, according to an instruction 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 and watching. The tour route display means 19 reads out tour route information of the tour route currently traveled by the observation vehicle selected by the work vehicle selection means 18 from the tour route information storage means 14, and displays the tour route on the map displayed on the display device 10. Hereinafter, on the management server 1 side, the tour route currently traveled by the observation vehicle is 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 present time on the map displayed on the display device 10. The trajectory of the observation route already traveled by the observation vehicle at the present time is called the "observation vehicle trajectory". The other vehicle trajectory acquisition means 21 acquires the trajectory of the observation route traveled by the other work vehicle other than the observation vehicle that is currently patrolling the observation route currently patrolled by the observation vehicle from the work vehicle trajectory storage means 15. The other work vehicle other than the observation vehicle that is currently patrolling the observation route is called the "other vehicle". Also, the trajectory of the observation route traveled by the other vehicle at the present 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 as to be distinguishable from the observation vehicle trajectory.

[0047] Fig. 3 is a block diagram showing the functional configuration of the vehicle-mounted terminal device 2 of Fig. 1. In Fig. 3, the management server 1 includes a display device 40, an input device 41, and a positioning device 42 as a hardware configuration. In addition, the management server 1 includes a vehicle position transmission means 43, a map information storage means 44, a tour route information storage means 45, a vehicle track information storage means 46, a different vehicle track information storage means 47, a map display means 48, a tour route selection means 49, a tour route display means 50, a viewing vehicle track display means 51, a different vehicle track acquisition means 52, and a different vehicle track display means 53 as a functional configuration. Each of these functional components is configured as a functional module in a computer by having the computer read and execute a program. It is assumed that the vehicle-mounted terminal device 2 stores the work vehicle ID of the work vehicle on which the vehicle-mounted terminal device 2 is mounted.

[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 locates the position (latitude and longitude) of the in-vehicle terminal device 2 in real time by 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 vehicle track information storage means 46 stores the toured track of the work vehicle 4 on which the vehicle-mounted terminal device 2 is mounted. Hereinafter, the work vehicle 4 on which the vehicle-mounted terminal device 2 is mounted is referred to as the "vehicle". The "vehicle" corresponds to the "monitoring vehicle" on the vehicle-mounted terminal device 2 side. Also, on the vehicle-mounted terminal device 2 side, the tour route on which the vehicle is currently patrolling (or about to patrol) is referred to as the "monitoring route". The other vehicle track information storage means 47 stores the toured tracks of each work vehicle other than the 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 itself that is currently traveling on the viewing route is called "other vehicle."

[0050] The map display means 48 reads out 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 according to a selection instruction input by an operator from the input device 41. The tour route display means 50 reads out the tour route (viewing route) selected by the tour route selection means 49 from the tour route information storage means 45 and displays the tour route on the map displayed on the display device 40. The viewing vehicle track display means 51 displays the own vehicle's completed tour track, which is the completed tour track of the own vehicle (viewing vehicle) on which the vehicle-mounted 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 "other vehicle's already traveled track" is a track that another vehicle patrolling the observation route that the vehicle is currently patrolling has traveled on the observation route. The other vehicle's track display means 53 reads out from the other vehicle's track information storage means 47 the already traveled track that another vehicle currently patrolling the observation route that the vehicle is currently patrolling has traveled on the observation route.

[0051] The operation of the mobile work support management system according to the first embodiment configured as above will be described below. First, the operation of the mobile terminal device 2 for supporting the work of the worker will be described, and then the operation of the management server 1 for supporting 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 Fig. 4 is a flowchart of an initial operation for supporting the work of an operator on the vehicle-mounted terminal device 2 side in the patrol work support management system according to the first embodiment. Fig. 4 shows the initial operation from when the vehicle-mounted terminal device 2 communicates with the management server 1 and acquires the latest tour route information to when it moves to the next tour guidance session. This operation is executed by communication between the vehicle-mounted terminal device 2 and the management server 1 via the communication line 3.

[0053] In step S001, the vehicle-mounted 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 vehicle-mounted terminal device 2, it extracts tour route information of 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 vehicle-mounted terminal device 2 (S013). The vehicle-mounted 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, one or more patrol routes are assigned to each business operator performing refuse collection work, and patrol route information for all businesses is stored in the patrol route information storage means 14. In the above step S012, one or more patrol routes assigned to the business operator specified by the work vehicle ID are extracted from the 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 vehicle-mounted terminal device 2, the tour route selection means 49 displays on the display device 40 a "route selection screen" for selecting a tour route to be traveled by the vehicle from among the tour routes stored in the tour route information storage means 45. The worker who operates the vehicle-mounted terminal device 2 performs a selection input to select one tour route from this "route selection screen" using the input device 41 (S021). When the selection input is performed, the map display means 48 displays on the display device 40 a map of the surroundings of the current position of the vehicle detected by the positioning device 42, and the tour route selection means 49 reads out 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 vehicle-mounted terminal device 2 transmits to the management server 1 the work vehicle ID of the vehicle, the tour route ID of the selected viewing route, and a tour guide session start request (S023). When the management server 1 receives (work vehicle ID, tour route ID, tour guidance session start request) from the vehicle-mounted 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 two hosts to the end of data communication when communication is performed between a client (vehicle-mounted terminal device 2) and a server (management server 1) in a computer network.

[0057] Next, the vehicle-mounted terminal device 2 detects the current position (latitude and longitude) of the vehicle by 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 vehicle to the management server 1 (S025). When the management server 1 receives (vehicle ID, position information) from the vehicle-mounted terminal device 2 (S052), the vehicle track 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 at which the observation vehicle is at the position q in the vehicle track storage means 15 as a track point of the toured track (S053). As a result, the vehicle track storage means 15 of the management server 1 continues to update the toured track of each work vehicle patrolling each tour route in real time.

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

[0059] When the other vehicle locus acquisition means 52 of the in-vehicle terminal device 2 receives this other vehicle completed trajectory 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 completed trajectories of other vehicles traveling 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 completed trajectory information received from the management server 1 is null information, the other vehicle locus acquisition means 52 cannot acquire even one other vehicle completed trajectory, so 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 viewing route from the tour route information storage means 45, and displays the viewing route on the map displayed on the display device 40 (S028). Next, the viewing 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. The other vehicle trajectory display means 53 reads out the already-traveled trajectories of other vehicles currently traveling on the viewing route (other vehicle already-traveled trajectories) from the other vehicle trajectory information storage means 47, and displays the already-traveled 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 viewed 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 by using a predetermined icon (S030).

[0061] Next, the vehicle-mounted terminal device 2 determines whether or not a work end instruction has been input from the input device 41 by the worker, and if a work end instruction has not been input, 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] Fig. 6 is a diagram showing an example of a map image displayed on the display device 40 of the in-vehicle terminal device 2 in the above-mentioned steps S027 to S030. Fig. 6(a) shows a map display screen when there is no other vehicle on the tour route (viewing route) on which the vehicle is currently traveling, and Fig. 6(b) shows a map display screen when there is another vehicle on the viewing route. In Fig. 6(a) and (b), the viewing route is displayed by a thick solid line in display color C1 (e.g., blue), the vehicle's toured track 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 vehicle's current position is displayed by a double circle icon in display color C2 (note that, since Fig. 6 shows a grayscale image that cannot be displayed in color, colors are omitted. The same applies below). In addition, in Fig. 6(b), the patrolled trajectory 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 Fig. 6(b) shows a case in which 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 a median strip on the observation route), but of course there are also cases in which the traveling directions of the own vehicle and the other vehicle are the same.

[0063] In Fig. 6, each work vehicle performs a door-to-door garbage collection operation to collect garbage placed in front of each house along the observation route while traveling along the observation route. As shown in Fig. 6(b), when a patrol operation of one observation route is performed by a plurality of work vehicles, the display device 40 displays the patrol operation trajectories of other vehicles in addition to the patrol operation trajectories of the own vehicle, so that the worker can grasp the progress of the patrol operation on the observation route, including the work progress of the other vehicles in addition to the own vehicle, and can grasp in real time the section on the observation route where the patrol operation has been completed. This prevents the vehicle from patrolling a section where the patrol operation has already been completed by another vehicle, thereby improving the work efficiency.

[0064] (2) Operations related to the support of the commander 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, as a prerequisite, capable of displaying 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 in 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 an icon of the current position of each work vehicle and the completed patrol path of the work vehicle are displayed on the map by the work vehicle selection means 18. Also, the information on the completed patrol 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, a commander who operates the management server 1 selects an icon of the current position of a work vehicle to be observed from among the icons of the current positions of each work vehicle displayed on the map, by 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 of the tour route (observation route) on which the observation car is currently traveling from the tour route information storage means 14. Also, the observation car track display means 20 reads out the toured track of the observation car (the toured track of the observation car) from the work vehicle track storage means 15, and acquires the current position of the observation car.

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

[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 out from the tour route information storage means 14 on the map displayed on the display device 40.

[0070] Next, in step S065, the observation car track display means 20 of the management server 1 reads out the completed tour track of the observation car (completed tour track of the observation car) from the work vehicle track 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 trajectory (other vehicle patrolled trajectory) of the other vehicle patrolling the observation route on which the observation vehicle is currently patrolling, from the work vehicle trajectory storage means 15. Here, the information on the patrolled trajectory 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 the information on the patrolled trajectory of the other vehicle is acquired in real time. Next, in step S067, the other vehicle trajectory display means 22 of the management server 1 displays the other vehicle patrolled trajectory acquired by the other vehicle trajectory acquisition means 21 on the map displayed on the display device 10 in a manner that makes it distinguishable from the patrolled trajectory of the observation vehicle, for example, by using a color different from that of the previously displayed patrolled trajectory of the observation vehicle. In this case, the screen display of the display device 10 becomes, for example, as shown in FIG. 6(b) described above.

[0072] Here, if there is no other vehicle traveling along the viewing route, no information on the other vehicle's traveled track is extracted in step S066, and the process of step S067 is omitted. In this case, the screen display of the display device 10 is, for example, as shown in FIG. 6(a) described above.

[0073] Next, in step S068, the management server 1 judges 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 an instruction to end the display has not been input, returns to the above-mentioned step S062 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, displays a map read from the map information storage means 13 on the display device 10 by the map display means 17, and displays on the map an icon of the current position of each work vehicle in the map display area and the trajectory of the work vehicle that has already been patrolled by the work vehicle by the work vehicle selection means 18, and ends the process.

[0074] In this way, when the patrol work of the observation route patrolled by one selected observation vehicle is being performed by a plurality of work vehicles, by displaying the completed patrol tracks of other vehicles patrolling the same patrol route in addition to the completed patrol track of the observation vehicle on the display device 10, 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 the patrol work has been completed. As a result, the commander can issue instructions to each work vehicle not to patrol sections where the patrol work has already been completed, thereby preventing the occurrence of unnecessary operational work and improving the overall work efficiency.

[0075] In this embodiment, an example of applying the present invention to a door-to-door garbage collection service has been described, but the present invention is not limited to garbage collection services, and can be similarly applied to delivery services for letters, packages or goods, and patrol services such as road sweeping. EXAMPLES

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

[0077] Fig. 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 the description thereof is omitted. In the management server 1 of this embodiment, compared to the first embodiment, a travel speed estimation means 30, a viewing vehicle progress estimation means 31, a different vehicle progress estimation means 32, a viewing vehicle predicted progress trajectory display means 33, a different 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 travel speed estimation means 30 calculates an estimated travel 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 travel speed" refers to the travel speed when the work vehicle 4 travels 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 both ends of each partial section when the tour route from the start point to the end point is divided into small partial sections. Figure 9 shows an example of dividing a tour route into partial sections. For example, assume that there is a tour route as shown in Figure 9(a). When dividing this tour route into partial sections, it is divided at each intersection or turning point on the tour route as shown in Figure 9(b). If the partial section divided at the intersection or turning point has a length of d or more, the partial section is further divided so that it has a length of d or less. In this way, when the tour route from the start point to the end point is divided into small partial sections, both ends (start point and end point) of each partial section are "each point on the tour route" (see Figure 9(c)). Also, "required time from the previous point" refers to the required time from the start point to the end point of a certain partial section when the tour route from the start point to the end point is divided into the above partial sections 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 therefore essentially indicates speed, in this specification, the "required time from the previous point" will also be referred to collectively as the "estimated operating speed."

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

[0081] The observation car progress estimation means 31 calculates the observation car's predicted progress trajectory based on the estimated travel speed at each point on the patrol route (observation route) on which the observation car is traveling. The "observation car's predicted progress trajectory" refers to the trajectory that the observation car will follow on the observation route within a predetermined time T from the 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 car will follow on the observation route in 10 minutes from the current position becomes the "observation car's predicted 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 vehicle other than the observation vehicle currently traveling on the observation route based on the estimated travel speed at each point on the observation route on 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 moves 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 arbitrarily set by the worker by making 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 operation participation vehicle selection means 35 selects a work vehicle to participate in patrol work for the observation route on 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." In addition, a request to a specific work vehicle to participate (support) in patrol work for a specific patrol route is called a "operation participation request." A work participation request is a request made by the commander to a worker in a participation requested vehicle.

[0085] When the 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 participating vehicle on the route of the patrol route related to the operation participation request. In addition, when the operation participation application described later is received from the vehicle-mounted terminal device 2, the operation start point determination means 36 determines the operation start point of the participation application vehicle on the route of the patrol route related to the operation participation application (hereinafter referred to as the "application route") of the work vehicle 4 (hereinafter referred to as the "participation application vehicle") related to the vehicle-mounted terminal device 2 that transmitted the operation participation application, and transmits information on the operation start point to the vehicle-mounted terminal device 2 of the participation application vehicle. Here, an application by a specific work vehicle to participate (support) in a patrol operation of a specific patrol route is called a "operation participation application". A operation participation application is a request made to the commander (or the management server 1) by the worker of the participation application vehicle who made the operation participation application. The "operation start point" refers to the point where the participation request vehicle or the participation application vehicle starts the patrol operation of 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 mobile operation support management system according to the second embodiment of the present invention. In Fig. 9, the same components as those in Fig. 3 of the first embodiment are given the same reference numerals and the description thereof is 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 business participation application sending means 62, and a business 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 observation vehicle predicted progress trajectory from the management server 1, it displays the observation 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 other vehicle predicted progress trajectory 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 business participation application sending means 62 sends a business participation application requesting participation in a patrol business of a specific patrol route to the management server 1 in accordance with instructions inputted from the input device 41 by the worker operating the in-vehicle terminal device 2. When the business start point display means 63 receives information on the business start point in response to the business participation application from the management server 1, it displays the business 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 the work of a worker on the vehicle-mounted terminal device 2 side in the tour work support management system according to the second embodiment. Note that the initial operation is similar to that in Fig. 4 of the first embodiment, and therefore a description thereof will be omitted. Also, in Fig. 11, the same reference numerals are used for the operation steps similar to those in Fig. 5 of the first embodiment, and a description thereof will be omitted.

[0092] In this embodiment, in step S025, (work vehicle ID, position information) is transmitted 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 transmitted the position information identified by the work vehicle ID is referred to as the "observation vehicle", and the patrol route currently being traveled by the 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 the information on the patrol paths of each work vehicle 4 that has previously traveled the observation route, which is stored in the work vehicle path storage means 15. Then, the observation car progress estimation means 31 of the management server 1 calculates the observation car predicted progress path for the observation car using the calculated estimated travel speed. At this time, the predicted time T of the observation car predicted progress path is assumed to be set in advance.

[0094] Furthermore, regarding 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 and store it in the memory within the management server 1, and this stored estimated operating speed may be used.

[0095] Next, in step S053_2, the other vehicle trajectory acquisition means 21 of the management server 1 reads out information (other vehicle patrol trajectory information) about the patrol trajectories (other vehicle patrol 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 the other work vehicles have traveled along the observation route (other vehicle patrol trajectories) from the work vehicle trajectory storage means 15.

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

[0097] Then, in step S054, the management server 1 transmits the observation vehicle's predicted progress locus information and the other vehicle's predicted progress locus information, in addition to the other vehicle's completed patrol locus information, to the observation vehicle's in-vehicle terminal device 2. Note that, if the work vehicle currently operating on the observation route is only the own vehicle, the other vehicle's completed patrol locus information and the other vehicle's predicted progress locus information are null information that does not include any other vehicle's completed patrol locus or other vehicle's predicted progress locus 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 completed trajectory information, the observed vehicle predicted progress trajectory information, and the other vehicle 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, a viewing vehicle predicted progress trajectory (host vehicle predicted progress trajectory), which is a predicted trajectory along which the host vehicle will proceed on the viewing 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, a other vehicle predicted progress trajectory, which is a predicted trajectory along which the other vehicle will proceed on the viewing 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 viewing vehicle track display means 51 of the vehicle-mounted 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 already-patrolled trajectory of the own vehicle and the already-patrolled trajectory of the other vehicle, the predicted progress trajectory of the observed vehicle (predicted progress trajectory of the own vehicle) and the predicted progress trajectory of the other vehicle are also displayed on the observation route. Fig. 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 viewing route is displayed by a thick solid line in display color C1 (e.g., blue), the vehicle's already 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; for example, red), the vehicle's current position is displayed by a double circle icon in display color C2, the other vehicle's already 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; for example, green), and the other vehicle's current position is displayed by a double circle icon in display color C3 (note that since Figure 12 is a grayscale image that cannot display colors, colors are omitted. The same applies below). Furthermore, the observed vehicle's predicted travel trajectory (own 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, although the example shown in Fig. 12 shows a case where the travel directions of the own vehicle and the other vehicle on the observation route are opposite to each other, there are of course cases where the travel directions of the own vehicle and the other vehicle are the same.

[0103] 12, when a patrol operation of one inspection route is performed by multiple work vehicles, by displaying the patrol operation trajectories of other vehicles in addition to the patrol operation trajectories of the own vehicle on the display device 40, the worker can grasp the progress of the patrol operation on the inspection route, including the work progress of the other vehicles in addition to the own vehicle, and can grasp in real time the section on the inspection route where the patrol operation has been completed. This makes it possible to prevent redundant patrols of sections where patrol operation has already been completed by other vehicles, and improves work efficiency. Furthermore, by displaying the observation vehicle's predicted progress trajectory (host vehicle's predicted progress trajectory) as the host vehicle moves along the observation route within a specified time from its current position, and the predicted progress trajectories of other vehicles operating on the same observation route as the host vehicle moves along the patrol route within a specified time from its current position, the worker aboard the observation vehicle can visually grasp how much progress will be made on the patrol work for this observation route within a specified time T, making it easier to decide whether or not to request additional support vehicles to share the patrol work for the observation route.

[0104] (2) Operations related to the support of the commander 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 mobile work support management system according to the embodiment 2. In Fig. 13, the same operation steps as those in Fig. 7 of the embodiment 1 are given the same reference numerals and the description thereof will be omitted.

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

[0106] In step S067, the other vehicle trajectory display means 22 of the management server 1 displays the other vehicle's completed patrol trajectory 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 travel speed calculated previously. In addition, the other vehicle predicted progress trajectory display means 34 of the management server 1 calculates the other vehicle's predicted progress trajectory 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 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 set in advance.

[0107] Then, in step S067_2, the observation vehicle predicted progress trajectory display means 33 of the management server 1 displays 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, on the map displayed on the display device 10 of the management server 1 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 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, on the map displayed on the display device 10 of the management server 1 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 on the patrol work within a specified time, 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 the work from the work vehicle to the management server Next, the operation of the patrol work support management system will be described in the case where a work vehicle is to newly join a patrol work on a patrol route along which another work vehicle is already operating.

[0110] FIG. 14 is a flow chart 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 a 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 participation of the application vehicle in the patrol business of the inputted 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 an 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 patrolled trajectories of each work vehicle 4 stored in the work vehicle trajectory storage means 15.

[0114] Next, in step S082, the task start point determination means 36 of the management server 1 determines the task start point of the participation application vehicle on the applied route. Here, if there is no work vehicle currently traveling on the applied route, the task start point determination means 36 determines the start point of the applied route as the task start point. Also, if there is a work vehicle currently traveling on the applied route (hereinafter referred to as "already participating vehicle"), the task start point (recommended entry point) is determined based on the estimated driving speed at each point on the applied route so that the sum (T1+T2) of the estimated travel time T1 that the already participating vehicle will take to travel on the applied route from the current time point onwards and the estimated travel time T2 that the participation application vehicle will take to reach the task start point from its current position and then travel on the applied route (however, the section on the applied route traveled by the already participating vehicle and the section on the applied route traveled by the participation application vehicle do not overlap) is minimized. This will be explained with reference to FIG. 15 for easy understanding. In Figure 14, the start point of the application route is q 0 , the end point is q 1 Then, the current location of the already participating vehicle on the application route is q 2 , the current location of the participating vehicle 3 , the starting point of the operation (recommended entry point) 4 The estimated travel time T1 that an already participating vehicle will take to travel along the applied route from the current time is the time from the current position q 2 From the starting point of business 4 This is the estimated time that the participating vehicle will travel to the current position q 3 From the starting point of business 4 The estimated time to reach the starting point of the work is T2a and the estimated time to reach the starting point of the work is q. 4 From the end point of the application route q 1 If the estimated time that the participation application vehicle travels to is T2b, the estimated travel time T2 of the participation application vehicle is T2a+T2b. The operation start point determination means 36 determines the position q of the operation start point so that the sum (T1+T2) is minimized. 4 Here, the participating car is at its current position q 3 From the starting point of business 4The estimated time T2a to reach the destination can be calculated based on the road information included in the map information, as in normal car navigation. 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 position 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 position 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 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 task start point displayed on the display device 40 of the in-vehicle terminal device 2. In Fig. 16, the task start point (recommended entry point) is shown 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 task start point is shown by an arrow.

[0117] (4) A request from the management server to the work vehicle to participate in the work FIG. 17 is a flow chart 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 viewing route, and in step S092, the tour route display means 19 of the management server 1 displays the viewing 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 already participating vehicle) of the work vehicle 4 currently traveling on the viewing route (hereinafter referred to as the "already participating vehicle") from the work vehicle trajectory storage means 15, and the other vehicle trajectory display means 22 displays the read out already participating vehicle toured trajectory on the map displayed on the display device 10.

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

[0120] Next, in step S 095 , the travelling speed estimation means 30 of the management server 1 calculates an estimated travelling speed at each point on the observation route based on the completed patrol trajectory 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 of 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 request vehicle. Then, in step S110, the in-vehicle terminal device 2 of the participation request 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 vicinity of 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 patrol route and the commander requests a participation request vehicle to join in support of the patrol work on that patrol 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 in the future and the time required for the patrol work that the participation request vehicle will perform in the future is minimized, making it possible to carry out the entire patrol work efficiently.

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