Garbage collection support management system and program

Abstract

To provide a garbage collection operation support management system capable of efficiently collecting special garbage such as pruned branches.SOLUTION: When a work vehicle performs garbage collection work while traveling along a normal patrol route for general garbage, if a worker finds special type garbage at a work point, the worker enters a location of the work point and type information of the special type garbage into an on-vehicle terminal device and sends the inputted items, as special collection point information, to a management server. The management server accumulates the special collection point information sent from each on-vehicle terminal device. In this way, by using the special collection point information collected during garbage collection operation on the normal patrol route for general garbage, it is possible to efficiently collect various types of special garbage.SELECTED DRAWING: Figure 8

Description

[Technical Field]

[0001] The present invention relates to a garbage collection operation support management system that supports and manages the garbage collection operations of each work vehicle in a garbage collection operation in which the work vehicle travels along a predetermined route and collects predetermined garbage. [Background technology]

[0002] "Garbage collection" is one of the processes in waste disposal, and refers to collecting garbage and transporting it to an incineration plant or a landfill. Also, the term "garbage collection work" refers to the work (continuous work or tasks related to a profession or business) in which a work vehicle (such as a garbage truck) travels along a predetermined route to collect garbage and transport it to a garbage collection site. To improve the operational efficiency of such garbage collection work, for example, garbage collection support management systems have been proposed, as described in Patent Documents 1 to 3.

[0003] In the garbage collection management system described in Patent Document 1, a management server controls the operation of garbage collection trucks (refuse trucks) in response to user requests, dynamically determines the garbage truck's route, and provides garbage collection services to users. In this system, when a garbage truck approaches a user's area, it simultaneously notifies the mobile phones or information communication devices of multiple users in the area via multicast distribution of "approaching garbage collection information" and "deadline for garbage disposal request replies." Users then reply to the management server from their mobile phones or information communication devices as garbage collection requests, including their "intention to dispose of food waste," "type of garbage" (e.g., "food waste"), and "quantity" (e.g., "three bags of food waste"). Upon receiving multiple garbage collection requests for the area, the management server stores the requests in a garbage collection database and uses route calculation software to determine the optimal collection route based on the standard route for the area. Then, using time calculation software, the management server calculates the optimal route by setting the garbage collection truck's speed to a constant, calculates the distance to the user's home where the garbage is to be collected, and calculates the estimated time of arrival at the user's home where the garbage will be disposed. The "estimated arrival time" and "location" are then notified to the user's mobile phone or information communication terminal, and at the same time, the "optimal route for garbage collection on that day" and the "estimated time of arrival at the user's house" are notified to the information communication terminal inside the garbage collection truck.

[0004] The bulky waste collection system described in Patent Document 2 is a system that centrally manages information about bulky waste collection. In this system, a user visits a nearby convenience store with a reception terminal, logs in to the server of the bulky waste collection center using the reception terminal, accesses a website for applying for bulky waste collection, and submits an application for bulky waste collection. The server uses the application information for bulky waste collection to list the collection points where bulky waste should be collected on the collection date and creates a collection route to visit these collection points. The server creates the collection route to be the shortest route in terms of distance and time for these collection points. The server then prints this collection route data on a collection route map using a printing device and distributes it to each collection vehicle. Alternatively, the server wirelessly transmits the collection route to a display device installed in the collection vehicle, which receives the collection route and displays it superimposed on the map on its screen.

[0006] [Non-Patent Document 1] Kaoru Suzuki, "Garbage Collection Methods," National Institute for Environmental Studies News, Vol. 39, No. 4, pp. 11-14, 2020. [Non-patent document 2] National Center for Industrial Property Information and Training, "2004 Patent Distribution Support Chart: Electricity 22: Car Navigation Route Search Technology," March 2005. Summary of the Invention [Problem to be solved by the invention]

[0007] In the conventional garbage collection support management system described above, users who put out garbage basically apply to the management center for collection of food waste and bulky garbage, and the management server creates a route for garbage collection operations based on the information provided by the application.

[0008] However, while the above-mentioned conventional system assumes that users (those who put out the garbage) will always contact the management center, in actual garbage collection sites, there are many cases where large garbage such as pruning branches and cardboard, non-combustible garbage like plastic, and hazardous garbage like lithium-ion batteries that cannot be contained in garbage trucks due to their risk of fire are disposed of without prior notice at garbage dumps for general garbage (places where various types of garbage, mainly from households, are accumulated until garbage trucks arrive to collect them). In this way, when specific types of garbage (hereinafter referred to as "special garbage") that cannot be collected by garbage trucks are disposed of, they cannot be left as they are for environmental hygiene or safety reasons, so separate collection trucks must be used to collect the special garbage. The days and locations where such special garbage is disposed of are irregular and cannot be predicted in advance. Therefore, when a worker makes another round to collect special waste, he or she must go around the normal route while checking each waste dump, which is inefficient.

[0009] On the other hand, if a worker discovers special waste that has not been reported in advance during a regular collection operation of general waste, the worker must contact the management center by phone or other means each time, and it is also inefficient for a special waste collection vehicle to head to the waste dump every time a call is received.

[0010] Therefore, an object of the present invention is to provide a garbage collection business support management system that enables efficient collection of special garbage when it is put out at a garbage dump without prior notice. [Means for solving the problem]

[0011] A first configuration of the garbage collection operation support management system according to the present invention is a garbage collection operation support management system that supports and manages garbage collection operations in which multiple work vehicles patrol a predetermined area to perform garbage collection operations, A management server; an on-board terminal device mounted on each work vehicle, the on-board terminal device having a display device, an input device, and a positioning device for measuring a current position, and capable of communicating with the management server via a communication line; Equipped with The management server a route storage means for storing normal route information, which is information about a normal route that a work vehicle follows within a predetermined area; a route information transmitting means for transmitting the normal route information of the normal route to the in-vehicle terminal device; Equipped with The in-vehicle terminal device a map display means for displaying a map image on the display device based on map information; a route display means for displaying the normal tour route on a map image displayed on the display device based on the normal tour route information transmitted from the management server; a type specification means for displaying on the display device an input area (hereinafter referred to as a "special type input area") for inputting the type of special type garbage (hereinafter referred to as "special type garbage") that has been put out at a location where garbage collection work is to be done (hereinafter referred to as a "work point"), and specifying the type of special type garbage that has been put out at the work point in accordance with input from the input device to the special type input area; For the task point on the normal tour route displayed on the display device, which is at a position determined by input from the input device or a position determined by the current position measured by the positioning device, (a) special type information, which is information on the type of special type waste put out at the work point, identified by the type identification means; and (b) location-specific information for identifying the location of the work point; Special collection point information, including special information transmission means for transmitting to the management server; Equipped with The management server further special collection point information storage means for storing information on the special collection points on the normal route; a special information updating means for receiving the special collection point information transmitted from the in-vehicle terminal device and storing the information in the special collection point information storage means; The present invention is characterized by the following features.

[0012] According to this configuration, when a worker discovers that special-type garbage has been disposed of at each work point while traveling along a normal route (collecting general garbage), the worker transmits the type of special-type garbage disposed of and the location of the work point from the on-board terminal device to the management server as special-type collection point information, and the management server stores information on the presence or absence and distribution of each type of special-type garbage. This enables the commander of the management server to determine whether to issue instructions for the collection of each type of special-type garbage, and also to issue instructions for the collection route for each type of special-type garbage based on the distribution information for each type of special-type garbage.

[0013] Here, "garbage collection work" refers to the work of a work vehicle traveling along a designated route, collecting garbage (trash), and transporting it to a garbage collection site. "Garbage collection task" refers to the work of collecting garbage at the location where each piece of garbage was disposed of. "Work vehicle" refers to a motor vehicle used for garbage collection work, such as a garbage truck or a truck for transporting bulky garbage. "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 cases where a worker carrying the on-board terminal device is riding on the work vehicle. "Task point" refers to the location where garbage collection work is performed, such as a garbage station (clean station) in the case of a station collection system or a garbage dump in the case of a door-to-door collection system. "Specific species refuse" refers to specific types of garbage. "Species" refers to each category of garbage (e.g., combustible garbage, non-combustible garbage, bulky garbage, etc.). "Specific species" refers to a specially designated category. Examples of "specific species" include pruning branches, lithium-ion batteries, plastic garbage, cardboard, and hazardous garbage. "Special species input area" refers to an input area displayed on a display device for inputting the type of special garbage. "Special species information" refers to information about the type of special garbage. "Special species collection point information" refers to information about the work point where specific types of garbage are collected, including (a) the special species information of the special garbage collected at the work point, as identified by a type identification means, and (b) location information identifying the location of the work point. The "location information" referred to here does not necessarily have to be coordinate information; for example, if the location of the work point is predetermined, the "location information" may be identification information identifying the work point.

[0014] A second configuration of the garbage collection business support management system according to the present invention is the first configuration, wherein the management server Based on the special collection point information stored in the special collection point information storage means, each type K of special waste is i Regarding the item K i a special collection route generating means for generating route information for a special collection route that travels around the work points where the special waste is disposed; Each item of special waste K i Regarding the item K i For the in-vehicle terminal device designated in advance regarding the item K i special collection route transmitting means for transmitting route information of the special collection route to the vehicle-mounted terminal device that has transmitted a signal related to an application to participate in the collection service; The present invention is characterized by the following features.

[0015] According to this configuration, the management server creates special collection routes based on distribution information for each type of special waste obtained during regular garbage collection (collection of general garbage) on regular routes, and distributes this information to the onboard terminal devices of the work vehicles that collect each type of special waste, allowing each work vehicle to carry out its regular collection efficiently.

[0016] Here, the "special collection route" refers to a route that goes around the work points where special waste of a specific type is collected. To "generate route information," a known route generation algorithm (see, for example, Non-Patent Document 2) such as those widely used in car navigation devices can be used. i The in-vehicle terminal device designated in advance for the item K refers to, for example, an in-vehicle terminal device of a work vehicle belonging to a contractor with whom a business contract has been concluded in advance. i The on-board terminal device that transmitted the signal related to the application for participation in the collection work for the item K is the terminal device that transmitted the signal related to the application for participation in the collection work for the item K via a communication line from the work vehicle (or the worker on board the work vehicle). iWhen a signal related to a participation application is sent to the management server as an indication of intent to participate in the collection work related to the above, it refers to the on-board terminal device mounted on the work vehicle that made the participation application. The "signal related to a participation application" may be any signal that can confirm the intention to participate, for example, a code signal that indicates a participation application, or a signal indicating intent to participate in the event K. i Examples of such requests include a request for delivery of route information for special collection routes.

[0017] A third configuration of the garbage collection business support management system according to the present invention is the first configuration, wherein the management server a fixed work point information storage means for storing fixed work point information, which is information including position identification information of each fixed work point, which is a work point whose position is predetermined on the normal patrol route; Equipped with the route information transmitting means transmits the normal route information of the normal route and the fixed work point information on the normal route to the in-vehicle terminal device; The in-vehicle terminal device a fixed work point display means for displaying the positions of the fixed work points on a map image displayed on the display device based on the fixed work point information transmitted from the management server, and / or displaying a fixed work point list, which is a list of the fixed work points, on the display device; Equipped with The type identification means displays on the display device a special type input area for inputting the type of special type waste that has been put out at the fixed work point displayed on the display device, the special type input area being selected by input from the input device or selected as the point that is closest to the current position measured by the positioning device, and identifies the type of special type waste that has been put out at the fixed work point in accordance with the input from the input device to the special type input area; The special information transmitting means, for the fixed work point selected by input from the input device or selected as the one closest to the current position measured by the positioning device, (a) special type information, which is information on the type of special type waste placed at the fixed work point, identified by the type identification means; and (b) location-specific information that identifies the location of the fixed work point; Special collection point information, including The information is transmitted to the management server.

[0018] According to this configuration, when garbage collection is performed on a normal route, one or both of the following (a) and (b) are displayed on the display device of the in-vehicle terminal device. (a) The normal patrol route is displayed on the map image, along with the location of the fixed work point. (b) A normal patrol route is displayed on a map image, along with a list of fixed work points. When the worker selects one of the fixed work points using the input device, or when the on-board terminal automatically selects one of the fixed work points closest to the current location determined by the positioning device, a special input area for inputting the type of special waste being disposed of at that fixed work point is displayed on the display device. When the worker inputs a type of special waste into this special input area using the input device, the type of special waste being disposed of at the fixed work point and the location of the work point are transmitted to the management server as special collection point information, and information on the presence or absence and distribution of each type of special waste is stored in the management server. This allows, in cases where work points are predetermined, such as in the station collection system, the management server to store information on the presence or absence and distribution of each type of special waste at each work point, making it possible to assist in determining whether to issue a collection instruction for each type of special waste and instructing the collection route for each type of special waste.

[0019] Here, a "station task point" refers to a task point whose location is predetermined. Specific examples include garbage stations (clean stations) in station collection systems and garbage collection points in other garbage collection operations. Note that garbage dumps in door-to-door collection systems (garbage dumps on each household's property facing the road) are not task points whose location is predetermined, and therefore do not qualify as "station task points."

[0020] A fourth configuration of the garbage collection operation support management system according to the present invention is the first configuration, wherein the in-vehicle terminal device a transmission decision means for displaying a transmission instruction input area on the display device for inputting a transmission instruction for special collection point information, and outputting a transmission instruction when the transmission instruction input area is selected by input from the input device; Equipped with The special information transmitting means is characterized in that when the transmission instruction is output by the transmission decision means, it transmits to the management server special collection point information including special information, which is information on the type of special waste put out at the work point identified by the type identification means, and location identification information that identifies the location of the work point, for the work point on the normal patrol route displayed on the display device, which is located at a position determined by the current position determined by the positioning device.

[0021] According to this configuration, when a worker aboard a work vehicle equipped with an on-board terminal device discovers special waste at a work point whose location is not predetermined, such as a garbage dump (a garbage dump on the property of each household facing the road) in a door-to-door collection system, the worker identifies the type of special waste at the work point using the type identification means and issues a transmission instruction using the transmission decision means. Then, the special waste information transmission means transmits the type of special waste at the fixed work point and the location of the work point to the management server as special collection point information, using the current location measured by the positioning device as the location of the work point. Information on the presence or absence and distribution of each type of special waste is stored in the management server. This allows the management server to accumulate information on the presence or absence and distribution of each type of special waste at each work point, even in cases where work points are not predetermined, such as in a door-to-door collection system, and supports the decision on whether to issue a collection instruction for each type of special waste and the issuance of a collection route for each type of special waste. The present invention is not limited to the door-to-door collection system, but can also be applied to a station collection system in which work points are determined in advance.

[0022] Here, the "send instruction input area" refers to an area displayed on a display device where a send instruction is entered, such as a send button (a button in a graphical user interface (GUI), which is a representation on a computer screen that the user presses to perform a send operation).

[0023] A fifth configuration of the garbage collection operation support management system according to the present invention is the second configuration, wherein the special collection route generation means The method is characterized in that it generates route information for a special collection route, which is a route that travels around the work points where the special waste of each type is disposed, based on the special collection point information on a plurality of the normal patrol routes stored in the special collection point information storage means, for each type of special waste.

[0024] According to this configuration, the special collection route generation means generates route information for a single special collection route by integrating special collection point information collected by on-board terminal devices mounted on work vehicles that patrol multiple normal routes, thereby enabling more efficient generation of special collection routes.

[0025] Here, the multiple regular routes to be integrated may be determined in advance, or the combination of multiple regular routes to be integrated may be changed in accordance with the distribution of work points (hereinafter referred to as "special collection points") where special waste is disposed on each regular route and the number of special collection points.

[0026] A sixth configuration of the garbage collection operation support management system according to the present invention is the second configuration, wherein the in-vehicle terminal device a locus information transmitting means for transmitting the current position measured by the positioning device as locus information to the management server at predetermined time intervals; Equipped with The management server a remaining travel time estimation means for calculating an estimated value (hereinafter referred to as the "estimated remaining travel time") T1 of the travel time required for the work vehicle B1 to travel from the current position Q1 of the work vehicle B1 specified by the trajectory information transmitted from the on-board terminal device mounted on each of the normal patrol routes (hereinafter referred to as the "normal patrol route R1") to the end point of the normal patrol route R1; Each item of special waste K i In response to the request, the special collection route generation means generates route information for the special collection route based on the special collection point information on the normal route R1 traveled by the work vehicle B1, which has been stored in the special collection point information storage means up to the present time, a confirmed special route travel time estimation means for calculating an estimated travel time T2 required for a work vehicle B2 performing garbage collection work to travel from the start point to the end point of the generated special collection route (hereinafter referred to as the "confirmed special collection route R2") (hereinafter referred to as the "confirmed special collection route estimated travel time"); Each item of special waste K i When the estimated remaining travel time T1 becomes less than or equal to the determined special collection route estimated travel time T2, The special collection route transmitting means distributes route information of the determined special collection route R2, The special collection route transmission means transmits route information of the determined special collection route to the on-board terminal device, and a dispatch command C(K) instructs the start of garbage collection work on the determined special collection route R2. i ) a dispatch command issuing means for transmitting the Each item of special waste K i Regarding After the current position Q1 of the work vehicle B1, which is specified by the trajectory information transmitted from the on-board terminal device mounted on the work vehicle B1 patrolling the normal patrol route R1, reaches the end point of the normal patrol route R1, The special collection route generation means generates route information for the special collection route based on the special collection point information on the partial section of the normal route R1 from the end point of the determined special collection route R2 to the end point of the normal route R1, which has been stored in the special collection point information storage means up to that point in time; The dispatch command issuing means issues the dispatch command C(K i a remaining special collection route transmitting means for distributing the route information to the in-vehicle terminal device that has transmitted the route information; The present invention is characterized by the following features.

Here, when the dispatch command issuance condition T1≦T2 is satisfied, it is assumed that when the work vehicle B2 performing garbage collection work on the special collection route R2 reaches the end point of the fixed special collection route R2, the work vehicle B1 performing garbage collection work on the normal patrol route R1 has reached the end point of the normal patrol route R1, and all remaining special collection points on the normal patrol route R1 have been fixed. Therefore, when the dispatch command issuance condition T1≦T2 is satisfied, the dispatch command issuance means issues a dispatch command C(K i ) is transmitted. When the work vehicle B1 reaches the end point of the normal patrol route R1 (or while the work vehicle B1 is on its way to the end point of the normal patrol route R1), the remaining special collection route transmitting means transmits a dispatch command C(K i ), route information for the special collection route that goes around the determined special collection points is generated and distributed to the on-board terminal device of the work vehicle B2. i ) is the confirmed special collection route R2 (K i When the vehicle reaches the end point of the special collection route or before that, route information for the remaining special collection routes has been distributed to the vehicle-mounted terminal device, so that garbage collection operations can continue on the remaining special collection routes.

[0028] In this way, before the work vehicle B1 performing garbage collection work on the normal route R1 reaches the end point of the normal route R1, i Dispatch command C (K) to work vehicle B2, which performs garbage collection work on the special collection route i By issuing the order, it will be possible to complete the entire garbage collection work in a shorter time, improving work efficiency.

[0029] Here, "travel time" refers to the time required to travel between two points. The "estimated remaining travel time" can be calculated statistically using the track information of the work vehicle when it traveled the regular route R1 in the past (information on the location of the work vehicle at each time). The "estimated travel time for the confirmed special collection route" can be calculated statistically using the road information included in the map information (information such as the distance between road nodes and speed limits) and the average patrol speed of the work vehicle, which is calculated based on the track information of the work vehicle when it traveled the special route in the past.

[0030] In addition, the management server may further include a trajectory information storage means, and a trajectory information update means that receives the trajectory information transmitted from the vehicle-mounted terminal device mounted on the work vehicle patrolling the normal patrol route and stores the trajectory information in the trajectory information storage means, and the remaining travel time estimation means may calculate the estimated remaining travel time T1 based on past movement trajectories related to the normal patrol route R1 stored in the trajectory information storage means.

[0031] A seventh configuration of the garbage collection work support management system according to the present invention is the sixth configuration, wherein the management server Each item of special waste K i The special collection route transmission means distributes route information of the special collection route. A starting point arrival travel time estimation means calculates an estimated value (hereinafter referred to as "starting point arrival estimated time") T20 of the travel time required for the work vehicle B2 to move from the current position of the work vehicle B2 equipped with the on-board terminal device specified by the trajectory information transmitted from the on-board terminal device to the starting point of the defined special collection route R2. Equipped with When the estimated remaining travel time T1 becomes equal to or less than the sum T2+T20 of the determined special collection route estimated travel time T2 and the estimated time to arrive at the starting point T20, the dispatch command issuing means issues a dispatch command C(K) to the in-vehicle terminal device to which the special collection route transmitting means distributes route information of the special collection route, instructing the start of garbage collection work on the special collection route. i ) is transmitted.

[0032] According to this configuration, when the current position of the work vehicle B2 scheduled to perform garbage collection work on the special collection route R2 is known, the dispatch command issuance condition T1≦T2+T20 (T20 is the estimated travel time from the current position of the work vehicle B2 to the starting point of the fixed special collection route R2 (estimated time to reach the starting point)) is used instead of the dispatch command issuance condition T1≦T2, so that the dispatch command C(K i ) will be issued, which will enable the entire garbage collection process to be completed in a shorter time, further improving work efficiency.

[0038] A second configuration of the program according to the present invention is characterized in that, by loading and executing the program into a computer built into an in-vehicle terminal device having a display device, an input device, and a positioning device for determining the current location, the in-vehicle terminal device functions as an in-vehicle terminal device having any one of the first, third, or fourth configurations. [Effects of the Invention]

[0039] As described above, the garbage collection operation support management system of the present invention does not require users (those who put out garbage) to contact the management center, so there is no decrease in efficiency due to user inaction (failure to contact). Furthermore, since information on the distribution of special garbage is collected during garbage collection on the regular route, there is no need to separately collect information on the distribution of special garbage. Furthermore, since information on the distribution of each type of special garbage is obtained during the first garbage collection tour on the regular route, there is no need to travel the entire regular route when collecting each type of special garbage, which makes it possible to efficiently perform mobile collection.

[0064] (2) System operation The operation of the garbage collection business support management system of this embodiment configured as above will now be described.

[0065] (2.1) Initialization Session First, the latest normal patrol route information and fixed work point information are downloaded from the management server 1 to the on-board terminal device 2 mounted on the service vehicle 4 that performs garbage collection work of general waste (household garbage) along the normal patrol route. The session in which this normal patrol route information and fixed work point information is downloaded is called the "initial setting session." Figure 4 is a flowchart showing the operation of the initial setting session in the garbage collection work support management system of Example 1.

[0066] First, in step S100, the tour route information update means 65 of the on-board terminal device 2 sends a route send request together with the work vehicle ID of the vehicle to the management server 1 in accordance with instructions input by the worker from the input device 51. Here, the "route send request" refers to a request command issued by the on-board terminal device 4 to the management server 1 requesting the distribution of normal tour route information.

[0067] Next, in step S110, when the management server 1 receives the (route transmission request, work vehicle ID) transmitted from the vehicle-mounted terminal device 2, in step S111 the tour route information transmission means 30 extracts from the tour route storage means 13 all normal tour route information for the normal tour route managed by the group (such as a garbage collection company) to which the work vehicle 4 with that work vehicle ID belongs, and also extracts all fixed work point information for each fixed work point on those normal tour routes. Then, in step S112, the tour route information transmission means 30 transmits all of the extracted normal tour route information and fixed work point information to the vehicle-mounted terminal device 2.

[0068] Next, in step S101, the in-vehicle terminal device 2 receives each ordinary tour route information and each fixed work point information transmitted from the management server 1, and in step S102 the tour route information update means 65 stores each received ordinary tour route information in the tour route storage means 54, and stores each received fixed work point information in the fixed work point information storage means 55. As a result, the ordinary tour route information in the tour route storage means 54 and the fixed work point information in the fixed work point information storage means 55 are updated to the latest information.

[0069] When the above operations of the initial setting session are completed, the process moves to the next patrol work session (steps S101, S113).

[0070] (2.2) Rotating Work Sessions A patrol work session is a session executed between the vehicle-mounted terminal device 2 and the management server 1 when a work vehicle performs garbage collection work at each fixed work point while traveling along its normal patrol route. In this embodiment, the "fixed work point" is a "garbage station (garbage ST)," so for simplicity, hereinafter, the "fixed work point" will be referred to as a "garbage ST" and "fixed work point information" will be referred to as "garbage ST information." Figure 5 is a flowchart showing the operation of a patrol work session in the garbage collection work support management system of embodiment 1.

[0071] First, in step S120, the in-vehicle terminal device 2 displays on the display device 50 a selection screen for selecting a normal patrol route stored in the patrol route storage means 54, and the worker on the work vehicle 4 on which the in-vehicle terminal device 2 is mounted selects one normal patrol route using the input device 51. When one normal patrol route R1 is selected, in step S121, the map display means 61 displays, on the display screen of the display device 50, a map image of a map of the area around the current position determined by the positioning device 52. Furthermore, the patrol route display means 62 displays the selected normal patrol route R1 on the map image displayed on the display device 50. Next, in step S122, the fixed work point display means 63 displays, on the map image displayed on the display device 50, the positions of the fixed work points on the normal patrol route R1, and also displays a list of the fixed work points (fixed work point list) on the display screen of the display device 50.

[0072] 6 shows an example of a screen displayed on the display screen of the display device 50. Here, the display screen of the display device 50 is a touch panel display, and also includes an input device 51.

[0073] In Figure 6, a map image is displayed in the map display area in the center of the screen, and a list of fixed work points (hereinafter referred to as the "ST list") is displayed in the ST list display area to the right of the map display area. Furthermore, below the ST list are a "Send button," which is a transmission instruction input area, and a "Garbage Presence / Absence Input Button" for inputting information (garbage presence / absence information) on whether or not garbage has been placed at the work point (garbage ST). The "Garbage Presence / Absence Input Button" is a radio button (exclusive options, i.e., a button form in which only one can be selected from the options) offering two choices: "Yes" (garbage present) and "No" (no garbage). On the map image, the patrol route (normal patrol route R1) is displayed with a thick line. In addition, each garbage ST is displayed with a square mark along the patrol route.

[0074] The ST list displays rectangular buttons for garbage STs (hereinafter referred to as "garbage ST buttons") along the patrol route in order, and the garbage ST button for the garbage ST that the work vehicle should head to next (hereinafter referred to as the "next garbage ST") is highlighted with a bold frame. The ST list is scrolled by the worker using a swipe or flick up or down. The number of the garbage ST (ST number) corresponding to each garbage ST button is displayed in the lower left corner of each garbage ST button. In addition, the completion time of that garbage collection work is displayed in the lower right corner of the garbage ST button for garbage STs for which garbage collection work has been completed, and the word "Incomplete" is displayed in the lower right corner of the garbage ST button for garbage STs for which garbage collection work has not been completed.

[0075] Returning to the flowchart of Figure 5, next, in step S123, the fixed work point display means 63 highlights the next garbage ST to which the work vehicle 4 should next head in the ST list displayed on the display screen of the display device 50 by surrounding it with a bold frame (see Figure 6).

[0076] Next, in step S124, the trajectory display means 68 acquires the trajectory information of the vehicle stored in the trajectory information storage means 56, acquires the current position of the vehicle measured by the positioning device 52, and displays the trajectory of the vehicle (vehicle trajectory) and the position of the vehicle (vehicle position) on a map displayed on the display screen of the display device 50. In Fig. 6, the vehicle trajectory is displayed by a series of dots, and the vehicle position is displayed by a bull's-eye dot mark.

[0077] Next, in step S125, the trajectory information update means 67 acquires the current position of the vehicle as determined by the positioning device 52, and updates the trajectory information of the vehicle stored in the trajectory information storage means 56 so as to add the pair of the acquired position and current time (position, time) to the trajectory information of the vehicle. Furthermore, when the trajectory information of the vehicle stored in the trajectory information storage means 56 is updated, the trajectory information transmission means 69 transmits the trajectory information (or information on the update difference) together with the vehicle's work vehicle ID to the management server 1. In step S131, the trajectory information update means 31 of the management server 1 receives the (vehicle ID, trajectory information) transmitted from the on-board terminal device 2, and in step S132, the trajectory information update means 31 uses the trajectory information to update the trajectory information of the vehicle 4 identified by the vehicle ID stored in the trajectory information storage means 15.

[0078] Next, in step S126, the in-vehicle terminal device 2 compares the current position of the vehicle with the position information of the next garbage ST to determine whether the vehicle has reached the next garbage ST, and if not, returns to step S123, and if it has reached, proceeds to the next step S127.

[0079] In steps S127 and S133, the in-vehicle terminal device 2 and the management server 1 execute the operation of the work record sub-session, which will be described later.

[0080] Next, in step S128, the vehicle-mounted terminal device 2 determines whether or not the garbage collection work for all garbage ST on the current normal patrol route R1 has been completed, and if not, returns to step S123, and if completed, ends the operation of the patrol work session.

[0081] (2.3) Work Record Sub-Session Next, the operation of the work recording sub-session executed in steps S127 and S133 of Fig. 5 will be described. Fig. 7 is a flowchart showing the operation of the work recording sub-session. Fig. 8 is a diagram showing an example of a screen displayed on the display screen of the display device 50 of the in-vehicle terminal device 2 during the work recording sub-session.

[0082] First, in step S140, the type identification means 73 of the in-vehicle terminal device 2 displays a special type input area on the display screen of the display device 50 for inputting the type of special waste disposed in the next waste ST. For example, as shown in FIG. 8, the special type input area is displayed in the upper right corner of the map display area in the center of the screen. The special type input area has an input field for inputting whether or not there is special waste of that type for each type of special waste. Each input field displays a radio button with two options: "Yes" (special type waste present) or "No" (no special type waste present). The worker taps to select this radio button to input the type of special waste disposed in the next waste ST. In the example of FIG. 8, the special type input area displays four fields for the types of special waste: "pruned branches ([Branches])," "lithium ion batteries ([Batteries])," "plastic ([Plastic])," and "cardboard ([Cardboard])." These types can be changed as needed depending on the work content.

[0083] Next, in steps S141 to S143, if the worker operates the input device 51 to input "present" for any of the special type garbage types in the special input area, the type specification means 73 of the in-vehicle terminal device 2 generates special collection point information that designates this next garbage ST as a special collection point, sets the position specification information of the special collection point information to the position specification information of the next garbage ST (position coordinates or the identification number (station ID) of the next garbage ST), and sets information on the one or more types that have been specified as "present" to the special information of the special collection point information. Also, if the worker operates the input device 51 to input "present" by pressing the "Garbage Presence / Absence Input Button" (see FIG. 8), the work history information update means 71 sets the garbage presence information in the work history information for this next garbage ST to "present," and if the worker operates the "Garbage Presence / Absence Input Button" to "absence," the work history information update means 71 sets the garbage presence information in the work history information for this next garbage ST to "absence."

[0084] Next, in step S143, if the "send button" (send instruction input area) is selected by the worker using the input device 51, the transmission determination means 75 determines that an instruction to send the work history information has been issued. Then, in step S144, the work history information update means 71 sets the information identifying the placement work point in the work history information for the next waste ST as the position identification information for the next waste ST, sets the date and time when the waste collection work was performed in the work history information as the current time, and stores these in the work history information storage means 57, and transmits this work history information together with the work vehicle ID of the user's vehicle to the management server 1. Furthermore, if special collection point information is generated in steps S141 to S143 above, the special information transmission means 74 stores this special collection point information in the special collection point information storage means 58, and transmits this special collection point information together with the work vehicle ID of the user's vehicle to the management server 1. Note that the special collection point information and work history information can also be transmitted together to the management server 1 together with the work vehicle ID.

[0085] In step S150, when the management server 1 receives (work vehicle ID, work history information, special collection point information) or (work vehicle ID, work history information) sent from the vehicle-mounted terminal device 2, in step S151 the special information update means 33 determines whether special collection point information is included, and if it is included, in step S152 the special information update means 33 stores the received special collection point information in the special collection point information storage means 18.

[0086] Next, in step S153, the work history information update means 32 stores the received work history information in the work history information storage means 17, and ends the operation of the work recording sub-session.

[0087] Through the above operations, special collection point information for the garbage ST where special garbage has been disposed is transmitted to the management server 1 from the on-board terminal device 2 of the service vehicle 4 performing regular garbage collection operations on the regular route, and this special collection point information is stored in the special collection point information storage means 18 of the management server 1. Then, when regular garbage collection operations on the regular route are completed, all special collection points are determined. In this way, based on the special collection point information stored in the special collection point information storage means 18, the commander operating the management server 1 can issue instructions regarding the collection of special garbage, thereby enabling efficient patrol collection of the special garbage disposed at each garbage ST.

[0088] (2.3) Operations from special collection route generation to dispatch orders Next, we will explain the system operation from generating special collection routes based on the special collection point information stored in the special collection point information storage means 18 of the management server 1 to issuing a dispatch command for special waste collection work. Here, we will explain two examples: a case where a commander manually issues a dispatch request / dispatch command, and a case where the management server 1 automatically issues a dispatch request / dispatch command.

[0089] (2.3.1) When a call for action is issued artificially 9 is a flowchart showing the process of generating special collection routes and issuing dispatch orders when a dispatch request and dispatch order are manually issued. The process of generating special collection routes and issuing dispatch orders is executed in parallel with the patrol work session shown in FIG. 6 on the management server 1.

[0090] First, the map information storage means 12 of the management server 1 displays a map image on the display screen of the display device 10, similar to the display of the map display area shown in Fig. 6, the patrol route storage means 13 displays each normal patrol route on the map image displayed on the display device 10, and the fixed work point information storage means 14 displays each fixed work point (garbage ST) on the map image displayed on the display device 10. Also, the work vehicle information display means 23 displays the trajectory and current position of each work vehicle 4 on the map image displayed on the display device 10, based on the trajectory information stored in the trajectory information storage means 15.

[0091] In step S160, the management server 1 determines whether special collection point information has been transmitted from the vehicle-mounted terminal device 2 (see steps S144 and S150 in FIG. 7). Upon receiving the special collection point information from the vehicle-mounted terminal device 2, in step S161, the management server 1 outputs a special collection point occurrence notification, displays the type of special waste included in the special collection point information on the display device 10, and displays the location of the special collection point on the map image displayed on the display device 10. The "special collection point occurrence notification" refers to a notification that notifies the commander that a special collection point for a certain type of special waste has occurred. For example, the display device 10 may display a notification that a special collection point has occurred, or an audio output device (not shown) may output an alarm notifying the commander that a special collection point has occurred. This allows the commander to recognize that a special collection point has occurred, and to recognize the type of special waste that has been disposed of at the special collection point and the location of the special collection point. Based on this information, the commander can issue instructions to the business operator that will be carrying out the collection of the special type of garbage to stand by and wait for deployment.

[0092] Next, in step S162, the special collection route generation means 34 of the management server 1 determines whether or not the garbage collection work on the normal patrol route (hereinafter referred to as the "monitoring route") patrolled by the work vehicle 4 (hereinafter referred to as the "monitoring work vehicle") equipped with the on-board terminal device 2 that transmitted the special information related to the special collection point occurrence notification has been completed. Here, the determination of whether or not the garbage collection work on the normal patrol route has been completed is made by referring to the work history information that is successively updated and accumulated in the work history information storage means 17.

[0093] If it is determined in step S162 that the garbage collection operation on the observation route patrolled by the observation work vehicle has not been completed, the process returns to step S160, and if it is determined that the garbage collection operation has been completed, the process proceeds to step S163. When the garbage collection operation on the observation route is completed, the positions of all special collection points on the observation route are determined.

[0094] Next, in step S163, the special collection route generation means 34 determines whether or not there is a special collection point on the observation route. If there is not, the special collection route generation / dispatch command issuance process is terminated; if there is, the process proceeds to the next step S164.

[0095] Next, in step S164, the special collection route generating means 34 generates the special collection point information (special collection point location information and special waste type information (special type information)) of each special collection point on the observation route stored in the special collection point information storage means 18 and the map information read out from the map information storage means 12, and calculates the number of special waste types K. i Regarding the item K i Route information is generated for a patrol route (special collection route) that travels around the fixed work points (garbage ST) where special garbage is disposed.

[0096] Here, at each special collection point on the observation route, multiple items K i (i=1,2,…,N k ;N k If special waste (number of items) is being disposed of, iA special collection route is generated for each special collection point. The route is generated based on road information included in the map information and the location information of the special collection point included in the special collection point information. A known route generation algorithm (see, for example, Non-Patent Document 2) can be used to generate the route.

[0097] Next, in step S164, the special collection route generating means 34 i The route information of the special collection route for each of the work vehicles 4 is stored in the special collection route storage means 19a. Next, in step S165, the special collection route transmission means 35 refers to the information about the work vehicles 4 stored in the work vehicle information storage means 19a, and stores the route information of the special collection route for each of the work vehicles 4. i A list of service vehicles available for garbage collection work (hereinafter referred to as the "dispatchable service vehicle list") is displayed on the display device 10. This allows the commander to check the dispatchable service vehicle list and assign the type K to each service vehicle 4 in the list. i When the request for dispatch is accepted, the vehicle terminal device 2 mounted on the accepting work vehicle 4 sends the request for dispatch for the special waste collection work of category K, as in FIG. i A route transmission request for the special collection route information for item K is sent to the management server 1, and in response, the special collection route transmission means 35 transmits the route information for the special collection route to the vehicle-mounted terminal device 2. i Category K according to the special collection route i It is possible to carry out garbage collection work for special garbage.

[0098] Figure 10 shows an example of the distribution of each special collection point on a regular route at the time when garbage collection work on the regular route is completed. Figure 11 shows an example of a special collection route generated by the special collection route generation means 34, which visits each special collection point in Figure 10. In Figures 10 and 11, garbage ST on the regular route is shown as a square, garbage ST where special garbage has not been disposed of is shown as a white square (□), and garbage ST where special garbage has been disposed of is shown as a black square (■). In Figure 10, the route with a thick line indicates the regular route, and in Figure 11, the route with a thick line indicates the special collection route.

[0099] Generally, special collection points are often sparsely distributed on regular routes, so it is inefficient to travel along regular routes when collecting special waste. On the other hand, in this embodiment, the special collection route generation means 34 generates a dedicated route (special collection route) for special waste collection, as shown in Figure 11, and special waste collection is carried out along this special collection route, thereby improving work efficiency.

[0100] (2.3.2) When a call for action or an order for action is automatically issued 12 is a flowchart showing the special collection route generation process on the management server side when a dispatch request and dispatch command issuance are performed automatically. This special collection route generation and dispatch command issuance process is executed in parallel with the patrol work session shown in FIG. 6 on the management server 1.

[0101] First, in step S170, the management server 1 determines whether or not special collection point information has been transmitted from the vehicle-mounted terminal device 2 (see steps S144 and S150 in FIG. 7). Upon receiving the special collection point information from the vehicle-mounted terminal device 2, in step S171, the management server 1 determines the type K of special waste from the special information included in the special collection point information (information specifying the location of the special collection point and information on the type of special waste (special information)). i Identify the special waste category K i For each event, iThe in-vehicle terminal device 2 of each pre-registered work vehicle 4 that performs the garbage collection work of the special garbage type K is i Identification number (specific type ID) and dispatch standby request Req (K i ) is transmitted. A "request for standby for dispatch" is a command signal requesting standby for dispatch for special waste collection work. Hereinafter, the work vehicle 4 equipped with the on-board terminal device 2 that transmitted this special waste collection point information will be referred to as the "monitoring work vehicle," and the normal patrol route that the monitoring work vehicle patrols will be referred to as the "monitoring route."

[0102] Dispatch standby request Req(K i ), when a dispatch acceptance application is returned from any of the vehicle-mounted terminal devices 2 together with the work vehicle ID related to that vehicle-mounted terminal device 2, in step S172, the management server 1 assigns the work vehicle 4 related to that work vehicle ID to category K. i The vehicle is registered with the work vehicle (hereinafter referred to as "contracted work vehicle") to be entrusted with the garbage collection work, and a dispatch reservation registration notice is sent to the vehicle-mounted terminal device 2. Here, "dispatch acceptance application" refers to a command signal offering to accept the garbage collection work for special garbage. "dispatch reservation registration notice" refers to a command signal notifying that the dispatch acceptance application has been accepted.

[0103] Then, in step S173, the special collection route generation means 34 of the management server 1 determines whether all garbage collection work on the observation route has been completed. Here, the determination of whether garbage collection work on the normal patrol route has been completed is made by referring to the work history information that is successively updated and accumulated in the work history information storage means 17. If it is determined that garbage collection work on the observation route patrolled by the inspection work vehicle has not been completed, the process returns to step S170, and if it is determined that it has been completed, the process proceeds to step S174. When garbage collection work on the observation route has been completed, the positions of all special collection points on that observation route have been determined.

[0104] Here, a certain event K i Regarding the above, once a contract work vehicle is registered, it will be iRegarding the standby request Req(K i ) will not be sent. Also, when the operations of steps S170 to S173 are completed, there may be cases where there is no dispatch acceptance application and the outsourced work vehicle has not been decided, in which case the pre-contracted work vehicle can be forcibly designated as the outsourced work vehicle, or the management server 1 can output a notification that the outsourcer is not registered, and in response to this notification, the commander can separately coordinate with the business operator in advance to designate the outsourced work vehicle as the outsourced work vehicle.

[0105] Next, in step S174, the special collection route generation means 34 determines whether or not there is a special collection point on the observation route, and if there is not, ends the special collection route generation / dispatch command issuance process, and if there is, proceeds to the next step S175.

[0106] Next, in step S175, the special collection route generating means 34 generates the special collection point information (special collection point location information and special waste type information (special type information)) of each special collection point on the observation route stored in the special collection point information storage means 18 and the map information read out from the map information storage means 12, and calculates the number of special waste types K. i Regarding the item K i Route information is generated for a patrol route (special collection route) that travels around work points (special collection points) where special waste is disposed.

[0107] Next, in step S176, the special collection route generating means 34 i The route information of the special collection route for each item K is stored in the special collection route storage means 19. i For the contract work vehicle registered for the category K i Next, in step S177, the dispatch command issuing means 36 transmits the route information of the special collection route for each item K for which the special collection route transmitting means 35 has transmitted the route information of the special collection route. i For the contracted work vehicle, the category K i Dispatch order C(K) to start garbage collection work on special collection routesi ) and completes the special collection route generation and dispatch command issuance process.

[0108] By the above operation, the management server 1 automatically i This will reduce the workload of commanders and improve efficiency, as requests will be made to dispatch garbage collection operations on special collection routes.

[0109] FIG. 13 is a flowchart showing the dispatch acceptance process on the vehicle-mounted terminal device 2 side when the management server 1 automatically issues a dispatch request.

[0110] Event K i In step S180, the on-board terminal device 2 mounted on the work vehicle 4 entrusted with the garbage collection work of the special garbage first receives a dispatch standby request Req(K i ) (see step S171), the on-board terminal device 2 sends a standby request Req(K i A dispatch request acceptance selection button is displayed on the display device 50 to prompt the operator to input whether or not to accept the dispatch request. If the operator uses the input device 51 to select not to accept, the process returns to step S180, and if the operator uses the input device 51 to select to accept, the process proceeds to the next step S182.

[0111] In step S182, the on-board terminal device 2 transmits a dispatch acceptance application to the management server 1 together with the work vehicle ID of the work vehicle on which the on-board terminal device 2 is mounted. In response, the on-board terminal device 2 receives a dispatch reservation registration notice (see step S172) from the management server 1. If the dispatch reservation registration notice is not received, it is assumed that a dispatch request has not been made, and the process returns to step S180.

[0112] Next, in step S183, the vehicle-mounted terminal device 2 waits to receive the special collection route information (see step S176) sent from the management server 1, and when the special collection route information is received, in step S184, the special collection route information update means 81 stores the received special collection route information in the special collection route storage means 59.

[0113] Next, in step S185, the event K transmitted from the management server 1 is i Dispatch order C(K) to start garbage collection work on special collection routes i ) (see step S177), the special collection route display means 82 displays the item K on the map displayed on the display device 50. i The special collection route of the item K is displayed on the map displayed on the display device 50. i Each special collection point on the special collection route is displayed. This is the same as in the case of a normal route. Then, the process proceeds to step S121 of the patrol work session described in Figure 5, and from then on, the process of the patrol work session is executed in the same way as in the case of a normal route (step S186).

[0114] Furthermore, when garbage collection work is performed on special collection routes, there is no need to identify special garbage again at each fixed work point (special collection point), so when garbage collection work is performed on special collection routes, the processing of steps S141 to S142 and S151 to S152 in the work record sub-session of Figure 7 is omitted. [Example]

[0115] In Example 2, a case where the present invention is applied to a garbage collection service using a door-to-door collection method (see Non-Patent Document 1) will be described. The "door-to-door collection method" refers to a garbage collection method in which garbage is placed in front of each house (on the premises of a home or business facing the road) and collected by a collection company (see Non-Patent Document 1). In the door-to-door collection method, there are no fixed work points (garbage ST), and each work vehicle (garbage truck) that performs garbage collection work collects garbage placed in front of houses while traveling along a set regular route. Therefore, here, the location where garbage is placed (garbage dump) on the premises of a home or business facing the road is defined as the "work point."

[0116] (1) System configuration The overall configuration of the garbage collection operation support management system is the same as that of the first embodiment shown in FIG. 1, and therefore a description thereof will be omitted.

[0117] The block diagram showing the functional configuration of the management server 1 is the same as that shown in Figure 2 of the first embodiment, so its explanation will be omitted. In this embodiment, since there are no fixed collection points (garbage ST), the fixed collection point information storage means 14 and fixed collection point display means 22 are not used. Furthermore, in the case of door-to-door collection, the location of the collection points is not fixed, so the garbage collection history for each collection point is not recorded. When the service vehicle 4 patrols along the normal route, it is considered that garbage collection work has been carried out on the section of the normal route. Therefore, the work history information storage means 17 and work history information update means 32 are not used.

[0118] The block diagram showing the functional configuration of the on-board terminal device 2 is the same as that shown in Figure 3 of the first embodiment, and a description of the similar configuration will be omitted. In this embodiment, since there are no fixed work points (garbage ST), the fixed work point information storage means 55 and the fixed work point display means 63 are not used. Also, as mentioned above, in the case of the door-to-door collection method, when the service vehicle 4 has traveled along the normal route, it is considered that garbage collection work has been carried out in the section of the normal route, and therefore the work history information storage means 57, work history information update means 71, and work history information transmission means 72 are not used either.

[0119] In this embodiment, when the work vehicle 4 is patrolling the normal route during garbage collection work, the display screen of the display device 50 does not display a "fixed work point list" as shown in FIGS. 6 and 8 of the first embodiment. Instead, a "special collection point list display area" that displays a list of registered special collection points is displayed. FIG. 14 shows an example of a screen displayed on the display screen of the display device 50 of the second embodiment. The "special collection point list display area" displays a vertical row of rectangular frames (hereinafter referred to as "list item frames") indicating confirmed special collection points. Each list item frame displays the location information of the special collection point, the registration number of the special collection point, and the registration time of the special collection point. In addition, the list item frame below the last registered list item frame displays a "next special collection point registration button" for registering the next special collection point. 6 and 8 in the first embodiment, a "left / right roadside input button" is displayed, which is a radio button for selecting whether the special collection point is on the left or right side of the road in the direction of travel of the normal route. Also, as shown in FIG. 14, the "special collection input area" is always displayed while traveling along the normal route.

[0120] The transmission decision means 75 displays a transmission instruction input area (send button) (see FIG. 14) on the display device for inputting an instruction to send special collection point information, and outputs a transmission instruction when the transmission instruction input area is selected by input from the input device 51. Furthermore, when a transmission instruction is output by the transmission decision means 75, the special information transmission means 74 transmits to the management server, for a work point located at a position determined by the current position measured by the positioning device 52, special collection point information including special type information, which is information on the type of special waste put out at the work point identified by the type identification means 73, and location identification information, which identifies the location of the work point.

[0121] (2) System operation In this embodiment, among the operations of the garbage collection work support management system, the operation of the patrol work session differs from that in the first embodiment, so the following describes the operation of the patrol work session in this embodiment.

[0122] 15 is a flowchart showing the operation of a patrol work session in the waste collection work support management system of Example 2. This patrol work session is a session executed between the on-board terminal device 2 of the work vehicle 4 and the management server 1 when the work vehicle 4 travels along a normal patrol route and performs waste collection work at each work point on the normal patrol route (a waste dump site on the premises of a home or business facing the road).

[0123] First, in step S200, the in-vehicle terminal device 2 displays on the display device 50 a selection screen for selecting a normal patrol route stored in the patrol route storage means 54, and a worker on the work vehicle 4 on which the in-vehicle terminal device 2 is mounted selects one normal patrol route R1 for door-to-door collection using the input device 51. When one normal patrol route R1 is selected, in step S201, the map display means 61 displays, on the display screen of the display device 50, a map image of a map of the area around the current position determined by the positioning device 52. In addition, the patrol route display means 62 displays the selected normal patrol route R1 on the map image displayed on the display device 50.

[0124] Next, in step S202, the type identification means 73 of the in-vehicle terminal device 2 displays on the display screen of the display device 50 a special type input area for inputting the type of special type waste placed in the next waste ST, and also displays a list of special type collection points (special type collection point list) in the special type collection point list display area on the display screen of the display device 50 (see FIG. 14). At this stage, since not a single special type collection point has been registered, the special type collection point list is empty, all list item boxes of the special type collection point list are marked "unregistered," and the topmost list item box displays a "next special type collection point registration button" for registering the next special type collection point. The type identification means 73 also displays on the display screen of the display device 50 a left / right roadside input button for selectively inputting information on whether the special type collection point is on the left or right side of the road as viewed in the direction of travel of the normal route. Furthermore, the transmission decision means 75 displays on the display screen of the display device 50 a transmission instruction input area (transmission button) for inputting an instruction to transmit the special collection point information.

[0125] Next, in step S203, the trajectory display means 68 acquires the trajectory information of the vehicle stored in the trajectory information storage means 56, and also acquires the current position of the vehicle measured by the positioning device 52, and displays the trajectory (vehicle trajectory) and position (vehicle position) of the vehicle on the map displayed on the display screen of the display device 50 (see Figure 14. In Figure 14, the vehicle trajectory is displayed by a series of dots, and the vehicle position is displayed by a bull's-eye dot mark).

[0126] Next, in step S204, the trajectory information update means 67 acquires the current position of the vehicle as determined by the positioning device 52, and updates the trajectory information of the vehicle stored in the trajectory information storage means 56 so as to add the pair of the acquired position and current time (position, time) to the trajectory information of the vehicle. Furthermore, when the trajectory information of the vehicle stored in the trajectory information storage means 56 is updated, the trajectory information transmission means 69 transmits the trajectory information (or information on the update difference) together with the vehicle's work vehicle ID to the management server 1. In step S220, the trajectory information update means 31 of the management server 1 receives the (vehicle ID, trajectory information) transmitted from the on-board terminal device 2, and in step S221, the trajectory information update means 31 uses the trajectory information to update the trajectory information of the vehicle 4 identified by the vehicle ID stored in the trajectory information storage means 15.

[0127] Here, when the worker aboard the work vehicle 4 arrives in front of a work point and discovers that special waste has been disposed of at that work point, he or she uses the input device 51 (touch panel) to input and set the type of special waste in the special waste input area (for example, if the type of special waste is "pruned branches," the radio button in the pruned branches ([Branches]) field in the special waste input area is set to "Yes" as shown in FIG. 14). Then, using the input device 51 (touch panel), the worker inputs and sets information on whether the work point where the special waste has been disposed of (special collection point) is on the left or right side of the road in the direction of travel of the normal route, using the left or right roadside input button. After the above settings, the worker uses the input device 51 (touch panel) to select the send button (send instruction input area) to confirm the special collection point information for the special collection point. Here, as described in Example 1, a "special collection point" refers to a work point on the normal route where special waste has been disposed of.

[0128] In step S205, the transmission decision means 75 of the in-vehicle terminal device 2 determines whether or not the transmission instruction input area has been selected by input from the input device 51. If it has not been selected, the process returns to step S203; if it has been selected, the transmission decision means 75 outputs a transmission instruction and proceeds to the next step S206.

[0129] Next, in step S206, the special type information transmitting means 74 determines whether any of the special type waste categories are set to "Yes" in the special type input area. If all of the special type waste categories are set to "No," the process returns to step S203. If any of the special type waste categories are set to "Yes," in step S207 the special type information transmitting means 74 sets the category set to "Yes" as the special type waste category, and generates special type collection point information that sets the position on the left or right road side closest to the current position as the position of the special type collection point. Here, whether the special type collection point is set to the left or right road side is determined based on the setting of the left or right road side input button.

[0130] As explained in Example 1, "special collection point information" refers to information about work points where specific types of garbage are disposed of, and includes (a) information about the type of special garbage disposed of at the work point (special information) identified by a type identification means, and (b) location identification information (in this example, location coordinate information) that identifies the location of the work point.

[0131] Next, in step S208, the special information transmission means 74 displays the generated special collection point information in the ``Next special collection point registration button'' column in the special collection point list displayed in the special collection point list display area on the display screen of the display device 50 (see the ``Confirmed special collection point'' list item frame in Figure 14), and moves the ``Next special collection point registration button'' to the list item frame one below.

[0132] Next, in step S209, the special information transmission means 74 stores the generated special collection point information in the special collection point information storage means 58, and transmits the special collection point information together with the work vehicle ID of the vehicle to the management server 1. Next, in step S222, when the management server 1 receives (the work vehicle ID, special collection point information) transmitted from the vehicle-mounted terminal device 2, the special information update means 33 stores the received special collection point information in the special collection point information storage means 18 in step S223.

[0133] The operations of steps S203 to S209 and S220 to S223 are repeatedly executed until the vehicle reaches the end point of the normal patrol route.

[0134] In parallel with this patrol work session, the special collection route generation and dispatch command issuance process described in FIG. 9 or FIG. 12 or FIG. 13 in the first embodiment is executed.

[0135] Through the above operations, special collection point information for work points (special collection points) where special garbage is disposed is transmitted to the management server 1 from the on-board terminal device 2 of the service vehicle 4 performing regular garbage collection work on the regular door-to-door collection route, and this special collection point information is stored in the special collection point information storage means 18 of the management server 1. Then, when regular garbage collection work on the regular door-to-door collection route is completed, all special collection points on that regular route are determined. In this way, based on the special collection point information stored in the special collection point information storage means 18, the commander operating the management server 1 can issue instructions regarding the collection of special garbage, thereby enabling efficient round-trip collection of special garbage disposed at each garbage station.

[0136] Figure 16 shows an example of the distribution of special collection points on a regular route at the time when garbage collection work on the regular route for door-to-door collection is completed. Figure 17 shows an example of a special collection route generated by the special collection route generation means 34 for door-to-door collection, which visits each special collection point in Figure 16. In Figures 16 and 17, garbage ST where special garbage is disposed is indicated by a rectangle. In door-to-door collection, there are no fixed work points (garbage ST), so only special collection points that are registered sequentially are sparsely located on the regular route for door-to-door collection. Then, as shown in Figure 17, the special collection route generation means 34 generates a dedicated route (special collection route) for special garbage collection work, and special garbage collection work is carried out along this special collection route, thereby improving work efficiency. [Example]

[0137] In Example 1, an example was described in which special collection route information was collected for one regular route where special collection points where special waste was disposed were collected to create a special collection route. In Example 3, an example is described in which special collection route information was collected for multiple regular routes where special collection points where special waste was disposed were collected to create a special collection route.

[0138] In Example 3, it is assumed that garbage collection operations are carried out in parallel on multiple regular routes by the service vehicles 4 in charge of each regular route. Of these multiple regular routes, two or more regular routes (hereinafter referred to as "routes to be integrated") that are integrated when creating one special collection route are designated R1(1), ..., R1(Nf). Nf is the number of routes to be integrated. Based on each special collection point registered by the garbage collection operations on each of the integrated routes R1(1), ..., R1(Nf), a special collection route that is created as a route that visits all of these special collection points is designated R2.

[0139] The areas where garbage collection is performed that are covered by each integrated route are assumed to be close to each other. Creating a special collection route by integrating regular routes that cover areas that are far apart would lead to a decrease in the efficiency of special garbage collection operations.

[0140] The integration target route may be predetermined, or may be appropriately selected and determined in accordance with the number and distribution of special waste collection points that occur. i It may be different depending on the type of special waste. i The frequency of garbage disposal varies depending on the event. i This is because the distribution density of special collection points differs for each route. In this embodiment, for simplicity of explanation, it is assumed that the integration target routes are predetermined.

[0141] The garbage collection work support management system of the third embodiment has an overall configuration similar to that shown in FIG. 1 of the first embodiment, a functional configuration of the management server 1 similar to that shown in FIG. 2 of the first embodiment, and a functional configuration of each vehicle-mounted terminal device 2 similar to that shown in FIG. 3 of the first embodiment. Furthermore, among the operations of the garbage collection work support management system of the third embodiment, the operations of the initial setting session and the patrol work session are similar to those of the first embodiment or the second embodiment. In the garbage collection work support management system of the third embodiment, the operations of the special collection route generation and dispatch command issuance process differ from those of the first and second embodiments.

[0142] Fig. 18 is a flowchart showing the operation of the special collection route generation and dispatch command issuance process of the garbage collection operation support management system of Example 3. Note that Fig. 18 shows the operation of the management server 1, similar to Fig. 12 of Example 1. In response to the operation of this management server 1, the operation of each vehicle-mounted terminal device 2 that accepts the dispatch request is the same as Fig. 13.

[0143] First, in step S300, the management server 1 determines whether special collection point information has been transmitted (see steps S144 and S150 in FIG. 7) from the on-board terminal device 2 of each work vehicle 4 patrolling each of the integration target routes R1(1), ..., R1(Nf). When special collection point information is received from any of the on-board terminal devices 2, in step S301, the management server 1 determines the type K of special waste from the special information included in the special collection point information (information specifying the location of the special collection point and information on the type of special waste (special information)). i Identify the special waste category K i For each event, i The in-vehicle terminal device 2 of each pre-registered work vehicle 4 that performs the garbage collection work of the special garbage type K is i A specific event ID and a call-out standby request Req(K i ) to send.

[0144] Dispatch standby request Req(K i ), when a dispatch acceptance application is returned from any of the vehicle-mounted terminal devices 2 together with the work vehicle ID related to that vehicle-mounted terminal device 2, in step S302, the management server 1 assigns the work vehicle 4 related to that work vehicle ID to category K. iThe vehicle is registered as a contracted work vehicle to be contracted for the garbage collection work, and a dispatch reservation registration completion notice is sent to the vehicle-mounted terminal device 2.

[0145] Then, in step S303, the special collection route generation means 34 of the management server 1 determines whether all garbage collection operations for each integration target route R1(1), ..., R1(Nf) have been completed. Here, the determination of whether garbage collection operations for each integration target route R1(1), ..., R1(Nf) have been completed is made by referencing the work history information that is successively updated and accumulated in the work history information storage means 17. If it is determined that garbage collection operations for any integration target route have not been completed, the process returns to step S300. If it is determined that garbage collection operations for all integration target routes R1(1), ..., R1(Nf) have been completed, the process proceeds to step S304. When garbage collection operations for all integration target routes R1(1), ..., R1(Nf) have been completed, the locations of all special collection points within the areas covered by these integration target routes R1(1), ..., R1(Nf) have been determined.

[0146] Here, a certain event K i Regarding the above, once a contract work vehicle is registered, it will be i Regarding the standby request Req(K i ) will not be sent. Also, when the operations of steps S300 to S303 are completed, there may be cases where there is no dispatch acceptance application and the outsourced work vehicle has not been decided, in which case the pre-contracted work vehicle can be forcibly designated as the outsourced work vehicle, or the management server 1 can output a notification that the outsourcer is not registered, and in response to this notification, the commander can separately coordinate with the business operator in advance to designate the outsourced work vehicle as the outsourced work vehicle.

[0147] Next, in step S304, the special collection route generation means 34 determines whether there is a special collection point on any of the integration target routes R1(1), ..., R1(Nf), and if there is not, terminates the special collection route generation / dispatch order issuance process, and if there is, proceeds to the next step S305.

[0148] Next, in step S305, the special collection route generation means 34 extracts the special collection point information of each special collection point on each integrated target route R1(1), ..., R1(Nf) stored in the special collection point information storage means 18, and generates a route map for each special collection point K for each special collection point K based on the extracted special collection point information (special collection point location information and special collection point type information (special information)) and the map information read out from the map information storage means 12. i Regarding the item K i Route information is generated for a patrol route (special collection route) that travels around work points (special collection points) where special waste is disposed.

[0149] Next, in step S306, the special collection route generating means 34 i The route information of the special collection route for each item K is stored in the special collection route storage means 19. i For the contract work vehicle registered for the category K i Next, in step S307, the dispatch command issuing means 36 transmits the route information of the special collection route for each item K for which the special collection route transmitting means 35 has transmitted the route information of the special collection route. i For the contracted work vehicle, the category K i Dispatch order C(K) to start garbage collection work on special collection routes i ) and completes the special collection route generation and dispatch command issuance process.

[0150] FIG. 19 is a diagram showing an example of two integration target routes R1(1) and R1(2) to be integrated and the special collection points registered on those routes. FIG. 20 is a diagram showing an example of a special collection route generated based on the special collection points registered on the integration target routes R1(1) and R1(2) in FIG. 19. In FIGS. 19 and 20, work points (special collection points) where special waste is disposed are indicated by rectangles. In FIG. 19, the integration target route R1(1) is indicated by a thick dashed line, and the integration target route R1(2) is indicated by a thick solid line. Also, in FIG. 20, the generated special collection route is indicated by a thick solid line. The special collection points registered on the integration target routes R1(1) and R1(2) are sparsely located on these routes. Because the areas covered by the integration target routes R1(1) and R1(2) are close to each other, the special collection points on these routes are distributed within a relatively concentrated area. Therefore, the special collection route generation means 34 generates a dedicated route (special collection route) for special waste collection operations, as shown in Figure 20, so as to visit all of the special collection points distributed within such a relatively concentrated area.

[0151] As described above, in the garbage collection work support management system of this embodiment, each special collection point on multiple integrated target routes R1(1), ..., R1(Nf) is integrated to generate a single special collection route, so that garbage collection work can be carried out using a single special collection route for special collection points distributed within a relatively concentrated area, thereby further improving the efficiency of special garbage collection work. [Example]

[0152] In the first and second embodiments, when one special collection route is generated from special collection points that occur on one normal route, an example is described in which a dispatch command for garbage collection work on the special collection route is issued after all garbage collection work on the normal route is completed. However, in the fourth embodiment, an example is described in which a dispatch command for garbage collection work on the special collection route is issued before the garbage collection work on the normal route is completed, without waiting for the garbage collection work on the normal route to be completed.

[0153] (1) Basic Concept In Example 4, a special collection route is generated and a dispatch command is issued without waiting for the completion of patrol work on the normal patrol route. This shortens the waiting time until the dispatch of the contracted work vehicle, further improving the efficiency of special waste collection work. However, in this case, it is expected that information on a work point (special collection point) where special waste has been subsequently disposed of in a section of the normal patrol route where waste collection work has not been completed at the time the dispatch command is issued will be sent to the management server 1. Therefore, in this case, it is necessary to add and update the special collection route during the special waste collection work on the special collection route for which the dispatch command was issued.

[0154] FIG. 21 shows the state of the normal route R1 and the special collection route R2(t) at time t when garbage collection work on the normal route R1 is incomplete. In FIG. 21, (a) shows the state of the normal route R1 at time t when garbage collection work is incomplete, and (b) shows the state of the special collection route R2(t) generated based on the special collection points established on the normal route R1 at time t. In FIG. 21, the starting point of the normal route R1 is indicated by a black square (■), and the end point of the route is indicated by a white square (□). The locations of the special collection points are indicated by a cross (×), and the position q1(t) at time t of the work vehicle B1 performing garbage collection work on the normal route R1 is indicated by a bull's-eye point (black dot in a circle).

[0155] At a certain time t when the garbage collection work on the normal route R1 is not completed, as shown in FIG. 21, special collection points P1, ..., P Np (Np is the number of special collection points) are found by a work vehicle B1 performing garbage collection work on this normal route R1 and are registered (saved) in the special collection point information storage means 18 of the management server 1.

[0156] The estimated travel time T1(t) for the work vehicle B1 to travel from its current position q1(t) to the route end point while performing garbage collection (i.e., the time required to travel between two points) is called the "estimated remaining travel time." The estimated remaining travel time T1(t) can be statistically calculated based on the movement trajectory of the work vehicle when it previously performed garbage collection on the normal route R1, which is stored in the trajectory information storage means 15. For example, if the average travel time from the current position q1(t) to the route end point, as determined from the movement trajectory, is E(T1) and the standard deviation is σ(T1), and assuming that the travel time follows a normal distribution, the estimated remaining travel time T1 can be calculated as T1(t) = E(T1) + α σ(T1) (α is a constant that determines the significance level. For example, if the one-sided significance level is 2.5%, α = 1.96).

[0157] In addition, the special collection points P1,...,P Np If the special collection route generated by the special collection route generating means 34 is defined as a determined special collection route R2(t) based on the above, the start point of the determined special collection route R2(t) is the special collection point P1, and the end point is the special collection point P Np The estimated travel time T2(t) of the work vehicle B2 when performing special waste collection work along this determined special collection route R2(t) is called the "determined special collection route estimated travel time." With regard to the determined special collection route estimated travel time T2, if the average travel speed v2 of the determined special collection route R2 is set to an appropriate value (for example, an average travel speed statistically determined from the travel trajectory during past special waste collection work), it can be calculated based on the distance of the determined special collection route R2(t), which is calculated based on the road information of the map information stored in the map information storage means 53.

[0158] Here, if the condition T1(t)≦T2(t) is satisfied, it is estimated that while the work vehicle B2 is performing its special waste collection work along the confirmed special collection route R2(t) determined at time t, all garbage collection work along the normal patrol route R1 by the work vehicle B1 will be completed, and during that time, all additional special collection points from the current position q1(t) on the normal patrol route R1 to the route end point will be determined. Therefore, when the condition T1(t)≦T2(t) is satisfied, a dispatch command can be sent from the management server 1 to the on-board terminal device 2 of the work vehicle B2. Such conditions that determine the timing of sending a dispatch command from the management server 1 to the on-board terminal device 2 of the work vehicle B2 are called "dispatch command issuance conditions."

[0159] Furthermore, if the current position q2 of work vehicle B2 at time t is known, the travel route and required time T20(t) from the current position q2(t) of work vehicle B2 to the starting point P1 of the defined special collection route R2(t) can be calculated using a route calculation algorithm that is typically used in car navigation systems, etc. Therefore, in this case, the condition for issuing a dispatch command can be set to T1(t) ≦ T2(t) + T20(t), allowing the dispatch command to be issued earlier.

[0160] After the dispatch command is issued, when all garbage collection work on the normal patrol route R1 by the work vehicle B1 is completed, all additional special collection points on the normal patrol route R1 from the position q1(t) to the route end point are determined. At this point, the special collection route generation means 34 determines the special collection points P Np An additional special collection route R2'(t) (hereinafter referred to as the "remaining special collection route") is generated that starts at and passes through all additional special collection points, and the route information of the additional special collection route is transmitted to the work vehicle B2. As a result, the work vehicle B2 can reach the end point P of the final special collection route R2(t). Np When it reaches , it can immediately switch to the garbage collection operation of special garbage on the remaining special collection route R2'(t).

[0161] (2) Configuration and operation The overall configuration of the garbage collection work support management system of the fourth embodiment is the same as that shown in FIG. 1 of the first embodiment, and the functional configuration of each vehicle-mounted terminal device 2 is the same as that shown in FIG. 3 of the first embodiment. Furthermore, among the operations of the garbage collection work support management system of the fourth embodiment, the operations of the initial setting session and the patrol work session are the same as those of the first embodiment or the second embodiment. In the garbage collection work support management system of the present embodiment, the functional configuration of the management server 1 is partially different from that of the first and second embodiments, and the operation of the special collection route generation and dispatch command issuance process is partially different from that of the first and second embodiments.

[0162] Fig. 22 is a block diagram showing the functional configuration of the management server 1 in the garbage collection work support management system of Example 4. In Fig. 22, components that are the same as those in Fig. 2 are given the same reference numerals and descriptions thereof will be omitted. Compared to Fig. 2, the management server 1 of this example additionally includes a remaining travel time estimation means 40, a confirmed special route travel time estimation means 41, a start point arrival travel time estimation means 42, and a remaining special collection route transmission means 43.

[0163] The remaining travel time estimation means 40 calculates the estimated remaining travel time T1 from the current position q1 of the work vehicle B1 identified by the trajectory information transmitted from the vehicle terminal device 2 mounted on the work vehicle B1 patrolling each normal route R1.

[0164] The determined special route travel time estimation means 41 is i Based on the special collection point information stored in the special collection point information storage means 18 up to the present time on the normal route R1 on which the work vehicle B1 is traveling, the special collection route generation means 34 generates a determined special collection route R2 (K i ) route information is generated, and the finalized special collection route R2(K i ) for the confirmed special collection route estimated travel time T2(K i ) is calculated.

[0165] The starting point arrival travel time estimation means 42 estimates the determined special collection route R2(K i ) to entrust the garbage collection work to the work vehicle B2 (K i ) from the current location of the confirmed special collection route R2 (Ki ) to the starting point of the work vehicle B2 (K i ) is the estimated time required to reach the starting point T20(K i ) is calculated.

[0166] teeth, The dispatch command issuing means 36 is i The conditions for issuing a dispatch command are judged for the dispatch command C(K i ) to work vehicle B2 (K i ) to

[0167] The remaining special collection route transmitting means 43 sends the dispatch command C(K i After the special collection route generation means 34 transmits the dispatch command C(K i ) related to the confirmed special collection route R2 (K i ) remaining special collection route R2'(K i ) and generate work vehicle B2 (K i ) to

[0168] 23 is a flowchart showing the process of generating special collection routes and issuing dispatch commands by the management server in the garbage collection work support management system of Example 4. For simplicity of explanation, the number of special garbage categories is assumed to be one (only category K1), and the subscript "(K1)" is omitted.

[0169] First, in steps S400 to S402, the management server 1 performs the process of requesting standby for dispatch and registering the outsourcing between the on-board terminal device 2 of the outsourced work vehicle that is outsourcing the special waste. This is the same as steps S170 to S172 in Fig. 12 of the first embodiment, so a detailed explanation will be omitted. Here, the work vehicle 4 that has been registered for outsourcing is referred to as outsourced work vehicle B2.

[0170] Next, in step S403, the confirmed special route travel time estimation means 41 of the management server 1 determines whether, at the current time t, special collection point information on the normal route R1 has been received from the service vehicle B1 patrolling the normal route R1 and registered in the special collection point display means 24 (i.e., whether one or more special collection points have been confirmed on the normal route R1). If not registered, the process proceeds to step S407; if registered, the process proceeds to the next step S404.

[0171] Next, in step S404, the confirmed special route travel time estimation means 41 acquires information about special collection points on the normal patrol route R1 that has been confirmed at the current time t from the special collection point information storage means 18, and generates route information for the confirmed special collection route R2(t) using the special collection route generation means 34. Furthermore, if the contracted work vehicle B2 is registered in step S402, the start point arrival travel time estimation means 42 generates route information from the current position q2(t) of the contracted work vehicle B2 to the start point of the confirmed special collection route R2(t), which is sent from the on-board terminal device 2 of the contracted work vehicle B2.

[0172] Next, in step S405, the confirmed special route travel time estimation means 41 calculates the confirmed special collection route estimated travel time T2(t) for the special collection route R2(t). In addition, the remaining travel time estimation means 40 acquires the current position of the work vehicle B1 from the trajectory information storage means 15, and calculates the estimated remaining travel time T1(t) from the current position of the work vehicle B1 to the end point of the regular patrol route R1. In addition, if the contracted work vehicle B2 is registered in step S402, the start point arrival travel time estimation means 42 calculates the start point arrival estimated time T20(t), which is an estimate of the travel time from the current position q2(t) of the contracted work vehicle B2 to the start point of the confirmed special collection route R2(t).

[0173] Next, in step S406, the dispatch command issuing means 36 determines whether the dispatch command issuing condition T1(t)≦T2(t) (if T20 has been calculated, T1(t)≦T2(t)+T20(t)) is satisfied. If the dispatch command issuing condition is satisfied, the process proceeds to step S408; if not, the process proceeds to the next step S407.

[0174] Next, in step S407, the management server 1 determines whether all garbage collection operations on the normal route R1 have been completed. If garbage collection operations on the normal route R1 have not been completed, the process returns to step S400. If garbage collection operations on the normal route R1 have been completed, there are no special collection points on the normal route R1, so the special collection route generation and dispatch command issuance process ends.

[0175] Next, in step S408, the special collection route transmission means 35 transmits route information for the confirmed special collection route R2(t) generated in step S404 to the on-board terminal device 2 of the contracted work vehicle B2. Next, in step S409, the dispatch command issuing means 36 transmits a dispatch command C(K1) to the on-board terminal device 2 of the contracted work vehicle B2, instructing the start of garbage collection work along the confirmed special collection route R2(t). This causes the contracted work vehicle B2 to start collecting special garbage along the confirmed special collection route R2(t).

[0176] Next, in step S410, the remaining special collection route transmission means 43 of the management server 1 monitors the trajectory information of the work vehicle B1, which is continuously updated in the trajectory information storage means 15 by the trajectory information update means 31, and waits until the garbage collection work on the normal patrol route R1 is completed.

[0177] When the garbage collection work on the normal circuit route R1 is completed, in step S411, the remaining special collection route transmission means 43 determines whether a new special collection point has been registered in the special collection point information storage means 18 in the section from the position q1(t) of the work vehicle B1 at the time t when the dispatch command C(K1) was sent to the end point of the normal circuit route R1 (hereinafter referred to as the "remaining normal circuit route R1'"). If a new special collection point has been registered, in step S412, the remaining special collection route transmission means 43 generates a remaining special collection route R2'(t) that starts from the end point of the determined special collection route R2(t) and travels through all of the special collection points on the remaining normal circuit route R1', and transmits this to the on-board terminal device 2 of the contracted work vehicle B2. As a result, when the contracted work vehicle B2 reaches the end point of the confirmed special collection route R2(t), it can continue to carry out the garbage collection work of special garbage on the remaining special collection route R2'(t). [Example]

[0178] In Example 5, another example will be described in which an early dispatch command for garbage collection work on a special collection route is issued before the garbage collection work on a regular route is completed. In Example 4, a case where one special collection route is generated based on special collection points on one regular route is described as a basic case in which an early dispatch command is issued, but in this example, a method will be described that can also be applied to the case where one special collection route is generated based on special collection points on multiple regular routes.

[0179] In Example 3, special collection routes were generated and dispatch orders were issued after garbage collection work was completed on all of the regular patrol routes (integration target routes) that served as the basis for creating special collection routes, but in Example 5, special collection routes are generated and dispatch orders are issued without waiting for garbage collection work on all integration target routes to be completed.This reduces the waiting time of contracted work vehicles that perform garbage collection work on special collection routes, thereby improving the work efficiency of garbage collection work for special garbage.

[0180] However, in this case, it is expected that information on special collection points will be sent to the management server 1 later on in a section of the integrated route where garbage collection work has not been completed at the time the dispatch order is issued. Therefore, in this case, it is necessary to add and update the special collection route in the middle of the garbage collection work for special garbage on the special collection route for which the dispatch order has been issued.

[0181] (1) Basic Concept When integrating special collection points on multiple routes to be integrated, the positional relationships of each special collection point also have an effect when generating a special collection route, so it is not possible to issue a dispatch command simply by comparing estimated travel times as in Example 4. Therefore, in order to incorporate the positional relationships of each special collection point, the area covered by the routes to be integrated is divided into multiple zones, and for each zone, the time it will take to complete garbage collection within that zone is estimated and a decision is made as to whether to issue a dispatch command.

[0182] First, let R1(1), ..., R1(Nf) be the routes to be integrated. Nf is the number of routes to be integrated, and is an integer equal to or greater than 1. The area covered by all routes to be integrated R1(1), ..., R1(Nf) is divided into multiple zones, and each zone is designated as Z1, Z2, ..., Z Nz Nz represents the number of zones.

[0183] Figure 24 shows an example in which the area covered by the integrated routes is divided into multiple zones. In this example, the area covered by two integrated routes, R1(1) and R1(2), is divided into four zones, Z1, Z2, Z3, and Z4. The integrated route R1(1) is shown with a thick dashed line, and the integrated route R1(2) is shown with a thick solid line. In addition, the current locations of the work vehicles B1(1) and B1(2) performing garbage collection work on the integrated routes R1(1) and R1(2) are indicated by bull's-eye dots, and the traveling directions of the work vehicles B1(1) and B1(2) are indicated by arrows.

[0184] In Figure 24, work vehicle B1(1) is in zone Z3, and work vehicle B1(2) is in zone Z4. In zones Z1 and Z2, garbage collection work has been completed on all integrated routes R1(1) and R1(2). In this way, when garbage collection work has been completed on all integrated routes within a zone, that zone is called a "work completed zone." If garbage collection work has not been completed on even one integrated route within a zone, that zone is called an "incomplete work zone." In Figure 24, zone Z3 is an incomplete work zone because garbage collection work has been completed on integrated route R1(2), but garbage collection work on integrated route R1(1) has not been completed. Zone Z4 is an incomplete work zone because garbage collection work has not been completed on both integrated routes R1(1) and R1(2).

[0185] 24, special collection points (confirmed special collection points) whose special collection point information has been sent to the management server 1 by the work vehicles B1(1) and B1(2) and registered are indicated by a cross (×). Special collection points (undetermined special collection points) that have not yet been passed by the work vehicles B1(1) and B1(2) and are not registered in the management server 1 are indicated by a triangle (△). Undetermined special collection points are special collection points that are scheduled to be confirmed when the work vehicles B1(1) and B1(2) pass through them in the future.

[0186] A Certain Zone Z k However, when the work incomplete zone changes to the work completed zone, at that point it becomes Zone Z k All special collection points within the zone are determined. In this way, a zone that has newly transitioned from an incomplete zone to a completed zone at a certain time t is called a "new zone" at time t. Therefore, at each time t, the new zone Z k Whenever this occurs, all work completion zones Z1 to Z2 at time t are k Special collection routes that circulate around the designated special collection points within the zone will be constructed on a zone-by-zone basis.

[0187] At some time t, zone Z itransitions from the incomplete zone to the completed zone, and at this time, zones Z1 to Z k is the work completion zone, Zone Z k+1 ~Z Nz In this case, the special collection route generation means 34 generates the zones Z1 to Z2. k A special collection route R2(t) (hereinafter referred to as the "confirmed special collection route") that visits all special collection points within the designated area is generated. The estimated travel time required for the work vehicle B2 performing garbage collection work on the confirmed special collection route R2 to travel is defined as the confirmed special collection route estimated travel time T2(t). In addition, the estimated remaining travel times (see Example 4) for each of the integration target routes R1(1), ..., R1(Nf) are defined as T1(1;t), ..., T1(Nf;t), and the maximum of these is defined as the estimated normal tour completion time T1(t) (T1(t) = max(T1(1;t), ..., T1(Nf;t))).

[0188] Figure 25 shows an example of a special collection route R2(t) that visits all special collection points in the work completion zones Z1 and Z2 that were determined at the time of Figure 24, and an example of a special collection route R2(t)+R2'(t) that visits all special collection points in zones Z1 to Z4.

[0189] Here, if the condition T1(t)≦T2(t) is satisfied, then while the service vehicle B2 is performing its special waste collection work along the confirmed special collection route R2(t) confirmed at time t, all garbage collection work by the service vehicles B1(1), ..., B1(Nf) on each integrated target route R1(1), ..., R1(Nf) will be completed, and during that time, all unconfirmed special collection points on each integrated target route R1(1), ..., R1(Nf) at time t will be confirmed and become confirmed special collection points. Therefore, when the condition T1(t)≦T2(t) is satisfied, a dispatch command can be sent from the management server 1 to the on-board terminal device 2 of the service vehicle B2. Such conditions that determine the timing of sending a dispatch command from the management server 1 to the on-board terminal device 2 of the service vehicle B2 are referred to as "dispatch command issuance conditions."

[0190] Furthermore, if the current position q2 of work vehicle B2 at time t is known, the travel route and required time T20(t) from the current position q2(t) of work vehicle B2 to the starting point of the defined special collection route R2(t) can be calculated using a route calculation algorithm that is typically used in car navigation systems, etc. Therefore, in this case, the condition for issuing a dispatch command can be set to T1(t) ≦ T2(t) + T20(t), allowing the dispatch command to be issued earlier.

[0191] After the dispatch command is issued, when all of the garbage collection work on each of the integrated target routes R1(1), ..., R1(Nf) by the work vehicles B1(1), ..., B1(Nf) is completed, the special collection route generation means 34 sets the end point of the confirmed special collection route R2(t) as the starting point and all of the additional special collection points (zone Z i+1 ~Z Nz An additional special collection route (hereinafter referred to as the "remaining special collection route") R2'(t) that passes through the final special collection point (special collection point within the designated area) is generated, and the route information of the additional special collection route is transmitted to the work vehicle B2. As a result, when the work vehicle B2 reaches the end point of the final special collection route R2(t), it can immediately switch to the garbage collection work of special garbage on the remaining special collection route R2'(t).

[0192] (2) Configuration and operation The overall configuration of the garbage collection work support management system of the fourth embodiment is the same as that shown in FIG. 1 of the first embodiment, and the functional configuration of each vehicle-mounted terminal device 2 is the same as that shown in FIG. 3. Of the operations of the garbage collection work support management system of the fifth embodiment, the operations of the initial setting session and the patrol work session are the same as those of the first embodiment or the second embodiment. In the garbage collection work support management system of the present embodiment, the functional configuration of the management server 1 is partially different from that shown in FIG. 2, and the operation of the special collection route generation / dispatch command issuance process is partially different from that of the third embodiment.

[0193] Fig. 26 is a block diagram showing the functional configuration of the management server 1 in the garbage collection work support management system of Example 5. In Fig. 26, components similar to those in Fig. 2 are given the same reference numerals and descriptions thereof will be omitted. Compared to Fig. 2, the management server 1 of this example additionally includes a remaining travel time estimation means 40, a confirmed special route travel time estimation means 41, a start point arrival travel time estimation means 42, a remaining special collection route transmission means 43, a work completion zone determination means 44, and a normal patrol completion time estimation means 45.

[0194] The remaining travel time estimation means 40 calculates the estimated remaining travel time T1(j) from the current position q1(j) of the work vehicle B1(j) identified by the trajectory information transmitted from the on-board terminal device 2 mounted on the work vehicle B1(j) patrolling each integrated target route R1(j) (j = 1, ..., Nf).

[0195] The work completion zone determination means 44 determines the zone Z based on the trajectory information transmitted from the vehicle terminal device 2 mounted on the work vehicle B1(j) traveling along each integration target route R1(j) (j=1, . . . , Nf). k For (k=1,…,Nz), the zone Z k is in the work completion zone.

[0196] The determined special route travel time estimation means 41 is i In response to this, the special collection route generation means 34 generates route information for the special collection route R2 based on the special collection point information of the special collection points within the work completion zone on the integrated target route R1(j) patrolled by each work vehicle B1(j) (j=1, ..., Nf) that has been stored in the special collection point information storage means 18 up to the present time, and calculates the confirmed special collection route estimated travel time T2 for the special collection route R2.

[0197] The starting point arrival travel time estimation means 42 calculates the estimated starting point arrival time T20 required for the work vehicle B2 entrusted with garbage collection work on the special collection route R2 to travel from its current position to the starting point of the special collection route R2.

[0198] Each time the work completion zone determination means 44 determines that all consecutive zones from zone Z(1) to zone Z(k) (k is any integer from 1 to Nz) are work completion zones, the normal tour completion time estimation means 45 calculates, using the remaining travel time calculation means 40, an estimated remaining travel time T1(j) for each integration target route R1(j) (j = 1, ..., Nf), and calculates an estimated normal tour completion time T1, which is the maximum of the Nf estimated remaining travel times T1(1), ..., T1(Nf) calculated.

[0199] The dispatch command issuing means 36 is i The conditions for issuing a dispatch command are judged for the dispatch command C(K i ) to work vehicle B2.

[0200] The remaining special collection route transmitting means 43 sends the dispatch command C(K i After the special collection route generation means 34 transmits the dispatch command C(K i ) generates a remaining special collection route R2' of the special collection route R2 relating to the above, and transmits it to the work vehicle B2.

[0201] 27 is a flowchart showing the process of generating special collection routes and issuing dispatch orders by the management server in the garbage collection work support management system of Example 5. For simplicity of explanation, the number of special garbage categories is assumed to be one (only category K1), and the subscript "(K1)" is omitted.

[0202] First, in steps S500 to S502, the management server 1 performs processing to request a standby call and register the outsourcing between the on-board terminal device 2 of the outsourced work vehicle that is outsourcing the special waste. This is the same as steps S170 to S172 in Figure 12, so a detailed explanation will be omitted. Here, the work vehicle 4 that has been registered for outsourcing is referred to as outsourced work vehicle B2.

[0203] Next, in step S503, the work completion zone determination means 44 of the management server 1 determines a zone (new zone) Z that has newly transitioned from a work incomplete zone to a work completed zone at the current time t.k Determine whether there is a new zone Z. k If not, the process proceeds to step S506, and if so, the process proceeds to the next step S504.

[0204] Next, in step S504, the determined special route travel time estimation means 41 calculates the travel time of the work completion zones Z1 to Zf among the special collection points on the integrated target route R1(j) patrolled by each work vehicle B1(j) (j=1, . . . , Nf) that are stored in the special collection point information storage means 18 up to the present time. k Based on the special collection point information of the special collection points in the list, the special collection route generation means 34 generates route information for a special collection route (confirmed special collection route) R2(t). Furthermore, if the contracted work vehicle B2 is registered in step S402, the starting point arrival travel time estimation means 42 generates route information from the current position q2(t) of the contracted work vehicle B2 to the starting point of the confirmed special collection route R2(t), which is sent from the on-board terminal device 2 of the contracted work vehicle B2.

[0205] Next, in step S505, the confirmed special route travel time estimation means 41 calculates the confirmed special collection route estimated travel time T2(t) of the confirmed special collection route R2(t) generated in step S504. Furthermore, if the contracted work vehicle B2 is registered in step S402, the starting point arrival travel time estimation means 42 calculates the starting point arrival estimated time T20(t), which is an estimate of the travel time from the current position q2(t) of the contracted work vehicle B2 to the starting point of the special collection route R2(t).

[0206] Next, in step S506, the work completion zone determination means 44 of the management server 1 determines all zones Z1, Z2, . . . , Z Nz If there is no work completion zone, the process proceeds to step S509, and if there is, the process proceeds to the next step S507.

[0207] Next, in step S507, the remaining travel time estimation means 40 acquires the current position of each vehicle B1(j) (j=1, ..., Nf) from the trajectory information storage means 15 and calculates the estimated remaining travel time T1(j;t) from the current position of vehicle B1(j) to the end point of the normal tour route R1(j).Then, the normal tour completion time estimation means 45 calculates the estimated normal tour completion time T1(t), which is the maximum of the calculated Nf estimated remaining travel times T1(1;t), ..., T1(Nf;t).

[0208] Next, in step S508, the dispatch command issuing means 36 determines whether the dispatch command issuing condition T1(t)≦T2(t) (if T20 has been calculated, T1(t)≦T2(t)+T20(t)) is satisfied. If the dispatch command issuing condition is satisfied, the process proceeds to step S510; if not, the process proceeds to the next step S509.

[0209] Next, in step S509, the management server 1 determines whether all garbage collection operations have been completed on all integration target routes R1(1), ..., R1(Nf). If garbage collection operations have not been completed on all integration target routes R1(1), ..., R1(Nf), the process returns to step S500. If garbage collection operations have been completed on all integration target routes R1(1), ..., R1(Nf), there are no special collection points on the integration target routes R1(1), ..., R1(Nf), so the special collection route generation and dispatch command issuance process ends.

[0210] Next, in step S510, the special collection route transmission means 35 transmits route information for the confirmed special collection route R2(t) generated in step S504 to the on-board terminal device 2 of the contracted work vehicle B2. Next, in step S511, the dispatch command issuing means 36 transmits a dispatch command C(K1) to the on-board terminal device 2 of the contracted work vehicle B2, instructing the start of garbage collection work along the confirmed special collection route R2(t). This causes the contracted work vehicle B2 to start collecting special garbage along the confirmed special collection route R2(t).

[0211] Next, in step S512, the remaining special collection route transmission means 43 of the management server 1 monitors the trajectory information of each work vehicle B1(1), ..., B1(Nf) that is continuously updated in the trajectory information storage means 15 by the trajectory information update means 31, and waits until garbage collection operations on all integrated target routes R1(1), ..., R1(Nf) are completed.

[0212] When the garbage collection work on all of the integrated target routes R1(1), ..., R1(Nf) is completed, in step S513, the remaining special collection route transmission means 43 determines whether there is a special collection point in the work incomplete zone as of time t when the dispatch command C(K1) was sent. If a special collection point is present, in step S514, the remaining special collection route transmission means 43 generates a remaining special collection route R2'(t) that starts from the end point of the confirmed special collection route R2(t) and travels to all special collection points in the work incomplete zone as of time t, and in step S515 transmits this to the on-board terminal device 2 of the contracted work vehicle B2. As a result, when the contracted work vehicle B2 reaches the end point of the confirmed special collection route R2(t), it can continue to collect special garbage along the remaining special collection route R2'(t).
