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 business support and management system that supports and manages the garbage collection business of each work vehicle in a garbage collection business where a work vehicle performs predetermined garbage collection while traveling along a predetermined tour route.

Background Art

[0002] "Garbage collection" is one of the steps of waste treatment, which means collecting garbage and transporting it to a place where a cleaning factory or landfill disposal is carried out. In addition, the operation (work or operation continuously carried out with respect to a profession, business, etc.) of a work vehicle (such as a garbage truck) traveling along a predetermined tour route while collecting garbage (refuse) and transporting it to a garbage collection site is called "garbage collection business". In order to improve the business efficiency of such a garbage collection business, for example, garbage collection support and management systems described in Patent Documents 1 to 3 have been proposed.

[0003] The garbage collection management system described in Patent Document 1 is such that the management server responds to the requests of users to control the operation of garbage collection trucks (dust carts), dynamically determines the operation routes of the dust carts, and provides garbage collection services to users. In this system, when a dust cart approaches the corresponding area where a user's address is located, "garbage collection approaching information" and "deadline for reply to garbage disposal requests" are simultaneously multicast to the mobile phones and information communication terminals of multiple users in the corresponding area. Users reply to the management server with "intention to dispose of raw garbage", "type of garbage" (e.g., "raw garbage"), "quantity" (e.g., "3 bags of raw garbage"), etc. as garbage collection requests from their mobile phones or information communication terminals. When the management server receives multiple garbage collection requests in the corresponding area, it saves the requests in the garbage collection DB, and based on the standard route in the corresponding area, uses route calculation software to determine the optimal collection route. Then, using time calculation software, it sets the speed of the garbage collection truck to be constant, calculates the optimal route, calculates the distance to the user's house where garbage is to be collected, and calculates the scheduled arrival time at the user's house where garbage is to be disposed of. Then, it notifies the user's mobile phone or information communication terminal of the "scheduled arrival time" and "location", and at the same time, notifies the information communication terminal in the garbage collection truck of the "optimal route for garbage collection on the day" and "scheduled arrival time at the user's house".

[0004] The bulky waste collection system described in Patent Document 2 is a system for centrally managing information on bulky waste collection. In this system, users go to a convenience store near which a reception terminal is installed, log in to the server of the bulky waste collection center via the reception terminal, access the homepage for applying for bulky waste collection, and apply for bulky waste collection. From these bulky waste collection application information, the server lists up the collection points where bulky waste should be collected on the collection date, and creates a collection route for touring these collection points. At this time, for these collection points, the collection route is created so as to be the shortest route in terms of distance and time. The server prints the collection route data as a collection route map by a printing device and distributes it to each collection vehicle. Or, the server wirelessly transmits the collection route to a display device installed on the collection vehicle, and the display device receives the collection route and displays it overlaid on a map on the screen.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In the above-described conventional garbage collection support management system, basically, users who dispose of garbage apply to the management center for the collection of household garbage and bulky waste, and the management server creates a collection route for the garbage collection operation based on the applied information.

[0008] However, in the above conventional system, it is premised that the user (the person who disposes of garbage) must always contact the management center. However, at the actual garbage collection site, there are various types of garbage such as pruning branches and cardboard boxes that are too large, non-combustible garbage such as plastic, and garbage such as lithium-ion batteries and hazardous waste that pose a risk of ignition and cannot be accommodated in the garbage truck. There are many cases where such garbage is disposed of at the garbage storage site for general garbage (a place where various types of garbage mainly from households are accumulated until the garbage truck comes for collection) without prior notice. Thus, when specific types of garbage (hereinafter referred to as "special garbage") that cannot be collected by the garbage truck are disposed of, it is not possible to leave them unattended from the perspective of environmental hygiene or safety. Therefore, it is necessary to separately conduct a special garbage collection operation by another collection vehicle. The days and locations where such special garbage is disposed of are irregular and cannot be predicted in advance. Therefore, when making a round during the special garbage collection operation again, the workers need to check each garbage storage site and make one round of the normal collection route, which has the problem of being inefficient.

[0009] On the other hand, during the general garbage collection operation, when the worker discovers that special garbage has been disposed of without prior notice, each time the worker contacts the management center by phone or the like, and each time such a contact is made, it is also inefficient for the special garbage collection vehicle to head to that garbage storage site.

[0010] Therefore, an object of the present invention is to provide a garbage collection operation support management system that can efficiently collect such special garbage when it is disposed of at the garbage storage site without prior notice.

Means for Solving the Problems

[0011] The 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 a garbage collection operation in which a plurality of work vehicles patrol a predetermined area and perform garbage collection operations, a management server, an in-vehicle terminal device mounted on each work vehicle, including a display device, an input device, and a positioning device for measuring the current position, and capable of communicating with the management server via a communication line, and is provided with The management server has a tour route storage means for storing normal tour route information which is information on a normal tour route in which a work vehicle patrols within a predetermined area, a tour route information transmission means for transmitting the normal tour route information of the normal tour route to the in-vehicle terminal device, and is provided with The in-vehicle terminal device has 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 the map image displayed on the display device based on the normal tour route information transmitted from the management server, displays an input area (hereinafter referred to as "special waste input area") for inputting the type of a specific type of waste (hereinafter referred to as "special waste") that is placed at a point where a garbage collection operation is performed (hereinafter referred to as "work point") on the display device, and specifies the type of special waste that is placed at the work point according to the input from the input device to the special waste input area. A type specifying means, For the work point on the normal tour route displayed on the display device at the position determined by the input from the input device or the position determined by the current position measured by the positioning device, (a) special information which is information on the type of special waste that is placed at the work point, specified by the type specifying means, and (b) position specifying information for specifying the position of the work point Special collection point information including a special information transmission means for transmitting to the management server, and is provided with The management server further special collection point information storage means for storing the special collection point information on the normal patrol route, special information update means for receiving the special collection point information transmitted from the in-vehicle terminal device and storing it in the special collection point information storage means, and is characterized by comprising the same.

[0012] According to this configuration, when performing normal garbage collection (general garbage collection) while patrolling the normal patrol route, if an operator discovers that special garbage is being discharged at each work point, the operator transmits, from the in-vehicle terminal device, the type of special garbage being discharged and the position of the work point as special collection point information to the management server, and information on the presence or absence and distribution of each type of special garbage is accumulated in the management server. As a result, the commander of the management server can determine whether to issue a collection instruction for each type of special garbage, and can also issue an instruction for the collection route of each type of special garbage based on the distribution information of each type of special garbage.

[0013] Here, the "garbage collection work" (refuse collection work) refers to the work of a work vehicle traveling along a predetermined circuit route to collect garbage (refuse) and transport it to a garbage accumulation site. The "garbage collection task" refers to the work of collecting garbage performed at the location where individual garbage is put out. The "work vehicle" refers to a motor vehicle used for performing the work of garbage collection, such as a garbage truck or a truck for transporting bulky waste. "Loading" refers to loading an in-vehicle terminal device onto a work vehicle or installing an in-vehicle terminal device on a work vehicle, including the case where a worker who possesses the in-vehicle terminal device rides on the work vehicle while possessing the in-vehicle terminal device. The "task point" refers to the location where the garbage collection task is performed, such as a garbage station (clean station) in the case of a station collection method or a garbage storage area in the case of a door-to-door collection method. "Specific species refuse" refers to garbage of a specific category. The "category" refers to each individual item obtained by classifying garbage (for example, items such as combustible garbage, non-combustible garbage, and bulky waste). The "specific species" refers to a specially defined category. Examples of the "specific species" include pruning branches, lithium-ion batteries, plastic garbage, cardboard, and hazardous waste. The "specific input area" refers to an input area for inputting the category of specific species refuse displayed on a display device. The "specific information" refers to information on the category of specific species refuse. The "specific collection point information" refers to information on the task point where specific species refuse is put out, including (a) the specific information on the specific species refuse put out at the task point identified by a category identification means, and (b) the position identification information for identifying the position of the task point. The "position identification information" mentioned here does not necessarily have to be coordinate information. For example, when the position of the task point is predetermined, the identification information for identifying the task point may be used as the "position identification information".

[0014] The second configuration of the garbage collection operation support management system according to the present invention is that, in the first configuration, the management server Based on the special collection point information stored in the special collection point information storage means, for each type K i of the special garbage, a special collection route generation means for generating route information of a special collection route, which is a tour route for touring the work points where the special garbage of the type K i is discharged, and For each type K i of the special garbage, for the in-vehicle terminal device specified in advance regarding the type K i , or for the in-vehicle terminal device that has transmitted a signal related to an application to participate in the collection operation regarding the type K i , a special collection route transmission means for distributing the route information of the special collection route, and is characterized by comprising.

[0015] According to this configuration, the management server creates a special collection route based on the distribution information of various types of special garbage obtained in the garbage collection operation of the normal tour route during normal garbage collection (collection of general garbage), and distributes it to the in-vehicle terminal device of the work vehicle that collects various types of special garbage, so that each work vehicle can perform circular collection efficiently.

[0016] Here, the "special collection route" refers to a tour route for touring the work points where specific types of special garbage are discharged. For "generating route information", a known route generation algorithm (for example, see Non-Patent Document 2) widely used in a car navigation device or the like can be used. The "in-vehicle terminal device specified in advance regarding the type K i " refers to, for example, the in-vehicle terminal device of a work vehicle belonging to a contractor who has a prior business contract. The "in-vehicle terminal device that has transmitted a signal related to an application to participate in the collection operation regarding the type K i " refers to the work vehicle (the worker on board) side, via a communication line, regarding the type K iWhen a signal related to an application to participate in the collection operation is transmitted to the management server, it refers to the in-vehicle terminal device mounted on the work vehicle that submitted the application. The "signal related to the application to participate" may be anything as long as it enables confirmation of the intention to apply. For example, a signal of a code representing the application to participate, or item K that also serves as an indication of the intention to apply for participation i Examples include a request for distribution of route information of a special collection route related to i .

[0017] The third configuration of the garbage collection operation support management system according to the present invention is, in the first configuration, the management server For each of the stationary work points that are the work points whose positions are predetermined on the normal tour route, stationary work point information storage means for storing stationary work point information which is information including the position identification information of the stationary work point is provided, The tour route information transmission means transmits the normal tour route information of the normal tour route and the stationary work point information on the normal tour route to the in-vehicle terminal device, The in-vehicle terminal device Based on the stationary work point information transmitted from the management server, the position of the stationary work point is displayed on the map image displayed on the display device, and / or a stationary work point list which is a list of the stationary work points is displayed on the display device. Stationary work point display means is provided, For the stationary work point selected by the input from the input device or selected as the one closest to the current position measured by the positioning device and displayed on the display device, a special input area for inputting the type of special garbage issued at the stationary work point is displayed on the display device, and according to the input from the input device to the special input area, the type of special garbage issued at the stationary work point is specified. The special item specifying means The special information transmission means is for the stationary work point selected by the input from the input device or selected as the one closest to the current position measured by the positioning device (a) Special information which is information on the type of special waste placed at the stationary work point, specified by the type specifying means, and (b) Position specifying information for specifying the position of the stationary work point Special collection point information including is transmitted to the management server, which is characterized in that.

[0018] According to this configuration, when performing the garbage collection business on the normal patrol route, on the display device of the in-vehicle terminal device, one or both of the following (a) and (b) are displayed. (a) The normal patrol route is displayed on the map image, and the position of the stationary work point is displayed. (b) The normal patrol route is displayed on the map image, and a list of stationary work points is displayed. Then, when an operator selects one of the stationary work points by the input device, or one of the stationary work points closest to the current position measured by the positioning device by the in-vehicle terminal device is automatically selected, a special input area for inputting the type of special waste placed at the stationary work point is displayed on the display device. When the operator inputs the type of special waste to the special input area by the input device, the type of special waste placed at the stationary work point and the position of the work point are transmitted to the management server as special collection point information, and information on the presence or absence and distribution for each type of special waste is accumulated in the management server. As a result, in the case where the work points are determined in advance as in the station collection method, information on the presence or absence and distribution for each type of special waste at each work point can be accumulated in the management server, and it becomes possible to assist in determining whether to issue a collection instruction for each type of special waste and in instructing a collection route for each type of special waste.

[0019] Here, the "station task point" refers to a work point with a predetermined position. Specifically, for example, a garbage station (clean station) in the station collection method, a garbage accumulation site in other garbage collection operations, etc. may be mentioned. Incidentally, the garbage storage site in the door-to-door collection method (the garbage storage site within the site facing the road of each household) does not correspond to the "station task point" because it is not a work point with a predetermined position.

[0020] The fourth configuration of the garbage collection operation support management system according to the present invention is that, in the first configuration, the in-vehicle terminal device displays a transmission instruction input area for inputting a transmission instruction for special collection point information on the display device, and when the transmission instruction input area is selected by an input from the input device, a transmission decision means for outputting a transmission instruction is provided, and when the transmission instruction is output by the transmission decision means, the special information transmission means transmits special collection point information including special information which is information on the type of special garbage issued at the work point specified by the type specifying means for the work point on the normal tour route displayed on the display device at a position determined by the current position measured by the positioning device and position specifying information for specifying the position of the work point to the management server.

[0021] According to this configuration, when a worker on a work vehicle equipped with an on-board terminal device finds special waste at a work point whose location is not predetermined, such as a garbage dump (a garbage dump in the premises of each household facing the road) in the case of a door-to-door collection method, the worker identifies the type of special waste at the work point by the type identification means at the work point and issues a transmission instruction by the transmission decision means. Then, the special information transmission means transmits the type of special waste at the fixed work point and the position of the work point as special collection point information to the management server, with the current position measured by the positioning device as the position of the work point, and the management server accumulates information on the presence or absence and distribution of each type of special waste. As a result, even in the case where a work point is not predetermined, such as in the case of a door-to-door collection method, the management server accumulates information on the presence or absence and distribution of each type of special waste at each work point, and it becomes possible to assist in judging whether or not to issue an instruction to collect each type of special waste and instructing the collection route of each type of special waste. Incidentally, 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 for inputting a send instruction displayed on a display device, such as a send button (a button in a graphical user interface (GUI), 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 comprises: The method is characterized in that it generates route information for a special collection route, which is a patrol route that patrols the work points where the special waste of each type is put out, based on the special collection point information on multiple 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 integrates the special collection point information collected by the in-vehicle terminal device mounted on the work vehicle that tours a plurality of normal tour routes, and generates route information for one special collection route. Thereby, it becomes possible to generate a more efficient special collection route.

[0025] Here, the plurality of normal tour routes to be integrated may be determined in advance, or according to the distribution status of the work points (hereinafter referred to as "special collection points") where special waste is discharged on each normal tour route, or the number of special collection points, the combination of the plurality of normal tour routes to be integrated may be changed.

[0026] The sixth configuration of the garbage collection operation support management system according to the present invention is, in the second configuration, the in-vehicle terminal device has a trajectory information transmission means for transmitting the current position measured by the positioning device to the management server as trajectory information at predetermined time intervals and the management server calculates an estimated value of the travel time (hereinafter referred to as "estimated remaining travel time") T1 required for the work vehicle B1 to move from the current position Q1 of the work vehicle B1 specified by the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle B1 that tours each of the normal tour routes (hereinafter referred to as "normal tour route R1") to the end point of the normal tour route R1. The remaining travel time estimation means, for each type K of the special waste i based on the special collection point information on the normal tour route R1 that the work vehicle B1 is touring, which is stored in the special collection point information storage means up to the current time, the special collection route generation means generates route information for the special collection route, and calculates an estimated value of the travel time (hereinafter referred to as "estimated travel time for the determined special collection route") T2 required for the work vehicle B2 to move from the start point to the end point of the generated special collection route (hereinafter referred to as "determined special collection route R2") to perform the garbage collection operation on the determined special collection route R2. The determined special route travel time estimation means For each type K of the special waste, i when the estimated remaining travel time T1 becomes less than or equal to the determined special collection route estimated travel time T2, the route information of the determined special collection route R2 is distributed by the special collection route transmission means, and a dispatch command issuing means for transmitting a dispatch command C(K i ) to instruct the in-vehicle terminal device to which the special collection route transmission means distributes the route information of the determined special collection route to start the waste collection operation on the determined special collection route R2; For each type K of the special waste, i with respect to, after the current position Q1 of the work vehicle B1 specified by the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle B1 traveling on the normal tour route R1 reaches the end point of the normal tour route R1, based on the special collection point information on the partial section of the normal tour route R1 from the end point of the determined special collection route R2 to the end point of the normal tour route R1 stored in the special collection point information storage means up to that point in time, the special collection route generation means generates the route information of the special collection route, and a remaining special collection route transmission means for distributing the route information to the in-vehicle terminal device to which the dispatch command issuing means has transmitted the dispatch command C(K i ); and It is characterized by comprising.

[0027] According to this configuration, at each time, the remaining travel time estimation means calculates the estimated remaining travel time T1 from the current position Q1 of the work vehicle B1 traveling on the normal tour route R1 to the end point. On the other hand, on the normal tour route R1, for type K iWhen a special collection point is detected, at each time, the special collection route generation means generates a confirmed special collection route R2 that tours the special collection points detected so far, and the confirmed special route travel time estimation means calculates an estimated value of the travel time of the confirmed special collection route R2 (confirmed special collection route estimated travel time) T2. Here, when the dispatch command issuance condition T1 ≤ T2 is satisfied, when the work vehicle B2 performing the garbage collection operation on the special collection route R2 reaches the end point of the confirmed special collection route R2, the work vehicle B1 performing the garbage collection operation on the normal tour route R1 has reached the end point of the normal tour route R1, and it is presumed that all the remaining special collection points on the normal tour route R1 have been determined. Therefore, when the above dispatch command issuance condition T1 ≤ T2 is satisfied, the dispatch command issuance means issues a dispatch command C(K i ) to the work vehicle B2. Then, when the work vehicle B1 reaches the end point of the normal tour route R1 (or during the period when the work vehicle B1 reaches the end point of the normal tour route R1), the remaining special collection route transmission means generates route information of the special collection route that tours the special collection points determined after the transmission of the dispatch command C(K i ), and distributes it to the in-vehicle terminal device of the work vehicle B2. As a result, the work vehicle B2(K i ) can continue to perform the garbage collection operation on the remaining special collection route as it is because the route information of the remaining special collection route has been distributed to the in-vehicle terminal device when it reaches or before reaching the end point of the confirmed special collection route R2(K i ).

[0028] In this way, by issuing a dispatch command C(K i ) to the work vehicle B2 performing the garbage collection operation on the special collection route of each item K i before the work vehicle B1 performing the garbage collection operation on the normal tour route R1 reaches the end point of the normal tour route R1, it becomes possible to complete the entire garbage collection operation in a shorter time, and the work efficiency is improved.

[0029] Here, the "travel time" refers to the time required to move between two points. The calculation of the "estimated remaining travel time" can be statistically estimated using the trajectory information of the work vehicle (information on the position points of the work vehicle at each time) when the normal tour route R1 was toured in the past. Also, for the "confirmed special collection route estimated travel time", it can be statistically estimated using the information on the roads included in the map information (information such as the distance between the node points of the road and the speed limit) and the average tour speed of the work vehicle obtained based on the trajectory information of the work vehicle when the special route was toured in the past.

[0030] Further, the management server further includes a trajectory information storage means and a trajectory information update means for receiving the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle that tours the normal tour route and storing it in the trajectory information storage means. As such, the remaining travel time estimation means can calculate the estimated remaining travel time T1 based on the past movement trajectory of the normal tour route R1 stored in the trajectory information storage means.

[0031] The seventh configuration of the garbage collection business support management system according to the present invention is, in the sixth configuration, the management server for each type K of the special garbage i an estimated value of the travel time required for the work vehicle B2 equipped with the in-vehicle terminal device identified by the trajectory information transmitted from the in-vehicle terminal device that distributes the route information of the special collection route to travel from the current position of the work vehicle B2 to the starting point of the confirmed special collection route R2 (hereinafter referred to as "estimated start point arrival time") T20, a start point arrival travel time estimation means is provided, when the estimated remaining travel time T1 becomes less than or equal to the sum T2 + T20 of the confirmed special collection route estimated travel time T2 and the start point arrival estimated time T20, the dispatch command issuing means sends a dispatch command C(K i ) to the in-vehicle terminal device that distributes the route information of the special collection route, instructing the start of the garbage collection business on the special collection route.

[0032] According to this configuration, when the current position of the work vehicle B2 scheduled to perform the garbage collection operation on the special collection route R2 is known, instead of the departure command issuance condition T1≤T2, by using the departure command issuance condition T1≤T2+T20 (T20 is the estimated travel time from the current position of the work vehicle B2 to the start point of the determined special collection route R2 (estimated start point arrival time)), it becomes possible to issue the departure command C(K i ) to the work vehicle B2 earlier, enabling the entire garbage collection operation to be completed in a shorter time and further improving the operational efficiency.

[0033] The eighth configuration of the garbage collection operation support management system according to the present invention is, in the second configuration, for each type K i of the special garbage, taking the normal circuit route R1(j) (j = 1,..., Nf; Nf is an integer of 1 or more) that is the basis for creating the special collection route related to the type K i as, regarding the area where the garbage collection operation is performed by all these normal circuit routes R1(j) (j = 1,..., Nf) as the operation target area, when the operation target area is divided into M (M is an integer of 2 or more) predetermined partial areas, each partial area is defined as zone Z(1),..., Z(M), among zones Z(1),..., Z(M), regarding the zone where the garbage collection operation in all the normal circuit routes R1(1),..., R1(Nf) passing through its interior has been completed as the operation completed zone, and the zone that is not the operation completed zone as the operation uncompleted zone, the in-vehicle terminal device is provided with trajectory information transmission means for transmitting, at predetermined time intervals, the current position measured by the positioning device to the management server as trajectory information , the management server An estimated value of the travel time required for the work vehicle to move from the current position of the work vehicle specified by the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle traveling on each of the normal tour routes to the end point of the normal tour route (hereinafter referred to as "estimated remaining travel time") is calculated by the remaining travel time estimation means. For each of the normal tour routes R1(j) (j = 1,..., Nf), the remaining travel time calculation means calculates the estimated remaining travel time for the normal tour route R1(j) (hereinafter referred to as "estimated remaining travel time T1(j)"). The normal tour completion time estimation means calculates the estimated normal tour completion time T1, which is the maximum value of the Nf calculated estimated remaining travel times T1(1),..., T1(Nf). Based on the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle traveling on each of the normal tour routes R1(j) (j = 1,..., Nf), the work completion zone determination means determines, for each zone, whether the zone is a work completion zone. At each time, when a zone that has transitioned from an unfinished work zone to a work completion zone is detected by the determination of the work completion zone determination means, For the type K of the special waste i Based on the special collection point information among the special collection point information on each of the normal tour routes R1(j) (j = 1,..., Nf) stored in the special collection point information storage means and located inside any work completion zone, the special collection route generation means generates route information of the special collection route. The estimated value of the travel time required for the work vehicle B2 to move from the start point to the end point of the generated special collection route (hereinafter referred to as "determined special collection route estimated travel time") T2 is calculated by the determined special route travel time estimation means. For each type K of the special waste i When the estimated normal tour completion time T1 is less than or equal to the determined special collection route estimated travel time T2, ​The route information of the determined special collection route R2 is distributed by the special collection route transmission means, and a dispatch command issuing means for transmitting a dispatch command C(K i ) to instruct the start of the garbage collection operation on the special collection route to the in-vehicle terminal device to which the special collection route transmission means distributes the route information of the special collection route; Regarding each type K i of special garbage, after the current position Q1(j) of the work vehicle B1(j) specified by the trajectory information transmitted from the in-vehicle terminal device mounted on the work vehicle B1(j) that circulates on each normal circulation route R1(j) (j = 1,..., Nf) reaches the end point of the normal circulation route R1(j), Based on the special collection point information located inside any of the work incomplete zones at the time when the dispatch command C(K i ) is transmitted among the special collection point information on each normal circulation route R1(j) (j = 1,..., Nf) stored in the special collection point information storage means, the route information of the special collection route is generated by the special collection route generation means, a remaining special collection route transmission means for distributing to the in-vehicle terminal device to which the dispatch command issuing means has transmitted the dispatch command C(K i ); It is characterized by comprising.

[0034] According to this configuration, even when integrating the special collection point information detected on a plurality of normal circulation routes R1(K i ,j) (j = 1,..., Nf) and generating the route information of one special collection route R2(K i ) for each type K i , before all of the work vehicles B1(j) performing the garbage collection operation on the normal circulation route R1(K i ,j) (j = 1,..., Nf) reach the end point of the normal circulation route R1(K i ,j), for the work vehicle B2(K i ) performing the garbage collection operation on the special collection route of each type K i , a dispatch command C(K iIt is possible to issue an order, enabling the entire garbage collection operation to be completed in a shorter time, thus improving work efficiency.

[0035] The ninth configuration of the garbage collection operation support management system according to the present invention is, in the eighth configuration, that the management server For each item K of the special garbage i From the current position of the work vehicle B2 equipped with the in-vehicle terminal device identified by the trajectory information transmitted from the in-vehicle terminal device that distributes the route information of the determined special collection route R2 by the special collection route transmission means, to the start point of the determined special collection route R2, an estimated travel time (hereinafter referred to as "estimated arrival time at the start point") T20 required for the work vehicle B2 to move is calculated by the start point arrival travel time estimation means is provided with When the estimated normal circuit completion time T1 is less than or equal to the sum T2 + T20 of the estimated travel time T2 of the determined special collection route and the estimated arrival time at the start point T20, the special collection route transmission means issues a dispatch command C(K i ) to the in-vehicle terminal device that distributes the route information of the special collection route, instructing the start of the garbage collection operation on the special collection route.

[0036] According to this configuration, when the current position of the work vehicle B2 scheduled to perform the garbage collection operation on the determined special collection route R2 is known, instead of the dispatch command issuance condition T1 ≤ T2, 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 start point of the special collection route R2 (estimated arrival time at the start point)) is used, enabling the dispatch command C(K i ) to be issued to the work vehicle B2 earlier, making it possible to complete the entire garbage collection operation in a shorter time and further improving work efficiency.

Effect of the Invention

[0039] As described above, according to the garbage collection business support management system according to the present invention, since it does not assume that the user (the person who produces garbage) contacts the management center, there is no efficiency reduction due to the randomness (non-contact) of the user. In addition, since information collection of the distribution of special garbage is performed during the garbage collection of the normal patrol route that is normally performed, there is no need to separately perform the information collection work of the distribution of special garbage. Further, since the distribution information of various types of special garbage can be obtained by the patrol of the garbage collection of the first normal patrol route, when collecting various types of special garbage, it is not necessary to patrol all of the normal patrol routes, so that the patrol collection can be performed efficiently.

[0064] (2) System operation Regarding the waste collection business support management system of this embodiment configured as described above, its operation will be described below.

[0065] (2.1) Initial setting session First, in the in-vehicle terminal device 2 mounted on the work vehicle 4 that initially performs the garbage collection operation of general waste (household waste) on the normal tour route, the in-vehicle terminal device 2 downloads the latest normal tour route information and fixed work point information from the management server 1. The session for downloading this normal tour route information and fixed work point information is called the "initial setting session". FIG. 4 is a flowchart showing the operation of the initial setting session in the garbage collection operation support management system of the first embodiment.

[0066] First, in step S100, the tour route information update means 65 of the in-vehicle terminal device 2 transmits a route transmission request together with the work vehicle ID of its own vehicle to the management server 1 according to an instruction input from the input device 51 by the operator. Here, the "route transmission request" (route send request) refers to a request command for the in-vehicle terminal device 4 to request the management server 1 to distribute the 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 in-vehicle terminal device 2, in step S111, the tour route information transmission means 30 extracts all the normal tour route information of the normal tour route that the group (such as a garbage collection contractor) to which the work vehicle 4 of the work vehicle ID belongs is responsible from the tour route storage means 13, and also extracts all the fixed work point information of each fixed work point on those normal tour routes. Then, in step S112, the tour route information transmission means 30 transmits all the extracted normal tour route information and fixed work point information to the in-vehicle terminal device 2.

[0068] Next, in step S101, when the in-vehicle terminal device 2 receives each normal tour route information and each fixed work point information transmitted from the management server 1, in step S102, the tour route information update means 65 stores each received normal 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. Thereby, the normal 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 operation of the above initial setting session ends, the process proceeds to the next patrol work session (Steps S101, S113).

[0070] (2.2) Patrol Work Session The patrol work session is a session executed by the in-vehicle terminal device 2 and the management server 1 when the work vehicle conducts garbage collection work at each stationary work point while patrolling the normal patrol route. In this embodiment, since the "stationary work point" is the "garbage station (Garbage ST)", hereinafter, for simplicity, the "stationary work point" will be referred to as "Garbage ST" and the "stationary work point information" will be referred to as "Garbage ST information". FIG. 5 is a flowchart showing the operation of the patrol work session in the garbage collection business 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 the normal patrol route stored in the patrol route storage means 54, and an operator of the work vehicle 4 equipped with the in-vehicle terminal device 2 selects one normal patrol route by means of 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 the area around the current position measured by the positioning device 52. Also, 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 stationary work point display means 63 displays on the map image displayed on the display device 50 the positions of the stationary work points on the normal patrol route R1, and also displays on the display screen of the display device 50 a list of stationary work points (stationary work point list).

[0072] Here, an example of the screen displayed on the display screen of the display device 50 is shown in FIG. 6. Here, it is assumed that the display screen of the display device 50 is a touch panel display and also serves as the input device 51.

[0073] In FIG. 6, a map image is displayed in the map display area at the center of the screen, and a stationary work point list (hereinafter referred to as the "ST list") is displayed in the ST list display area on the right side of the map display area. Further, below the ST list, a "transmission button" which is a transmission instruction input area, and a "garbage presence / absence input button" for inputting information on whether or not garbage has been put out at a work point (garbage ST) (garbage presence / absence information) are displayed. The "garbage presence / absence input button" is a radio button for choosing between "present" (garbage present) and "absent" (no garbage) (exclusive options, that is, a button form in which only one option can be selected from the options). On the map image, a tour route (normal tour route R1) is displayed in bold. Also, along the tour route, each garbage ST is displayed as a square mark.

[0074] In the ST list, rectangular buttons of garbage STs along the tour route (hereinafter referred to as "garbage ST buttons") are arranged and displayed in order, and the garbage ST button of the garbage ST that the work vehicle should go to next (hereinafter referred to as the "next garbage ST") is highlighted with a thick frame. The ST list is scrolled by a vertical swipe operation or a flick operation by the operator. At the lower left of each garbage ST button, the number (ST number) of the garbage ST corresponding to that garbage ST button is displayed. Also, at the lower right of the garbage ST button of the garbage ST for which the garbage collection work has been completed, the work completion time of that garbage collection work is displayed, and at the lower right of the garbage ST button of the garbage ST for which the garbage collection work is incomplete, "incomplete" is displayed.

[0075] Returning to the flowchart of FIG. 5, next, in step S123, the stationary work point display means 63 highlights, with a thick frame, the next garbage ST that the work vehicle 4 should go to next in the ST list displayed on the display screen of the display device 50 (see FIG. 6).

[0076] Next, in step S124, the trajectory display means 68 acquires the trajectory information of the host vehicle stored in the trajectory information storage means 56, and also acquires the current position of the host vehicle measured by the positioning device 52, and displays the trajectory of the host vehicle (host vehicle trajectory) and the position of the host vehicle (host vehicle position) on the map displayed on the display screen of the display device 50. In FIG. 6, the host vehicle trajectory is displayed by dot sequence marks, and the host vehicle position is displayed by crosshatch marks.

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

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

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

[0080] Next, in step S128, the in-vehicle terminal device 2 determines whether the refuse collection work for all the refuse STs on the current normal tour route R1 has been completed. If not completed, it returns to step S123, and when completed, it ends the operation of the tour work session.

[0081] (2.3) Work recording 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 in the work recording sub - session.

[0082] First, in step S140, the item - specifying means 73 of the in - vehicle terminal device 2 displays a special - input area for inputting the item of the special waste put out in the next waste ST on the display screen of the display device 50. For example, as shown in FIG. 8, the special - input area is displayed in the upper - right corner of the map - display area in the center of the screen. In the special - input area, an input field for inputting the presence or absence of the special waste of each item is provided for each item of the special waste. In each input field, a radio button for selecting either "Yes" (there is special waste) or "No" (there is no special waste) is displayed, and the operator taps and selects this radio button to input the item of the special waste put out in the next waste ST. In the example of FIG. 8, four columns of "pruning branches ([branches])", "lithium - ion battery ([battery])", "plastic ([pl])", and "cardboard ([cardboard])" are displayed in the special - input area as items of the special waste. These items can be appropriately changed according to the work content.

[0083] Next, in steps S141 to S143, when an input is made by the input device 51 through the operation of the operator such that the type of any special waste in the special input area is set to "yes", the item specifying means 73 of the in-vehicle terminal device 2 generates special collection point information designating this next waste ST as a special collection point, sets the position specifying information of the special collection point information to the position specifying information (position coordinates or the identification number (station ID) of the next waste ST) of the next waste ST, and sets the information of one or more types set to "yes" to the special information of the special collection point information. Further, when an input is made by the input device 51 through the operation of the operator such that the "waste presence / absence input button" (see FIG. 8) is set to "yes", the work history information updating means 71 sets the waste presence / absence information in the work history information of this next waste ST to "yes", and when an input is made such that the "waste presence / absence input button" is set to "no", the work history information updating means 71 sets the waste presence / absence information in the work history information of this next waste ST to "no".

[0084] Next, in step S143, when the "transmission button" (transmission instruction input area) is selected by the input device 51 through the operation of the operator, the transmission determination means 75 determines that a transmission instruction has been made for the work history information. Then, in step S144, the work history information updating means 71 sets the specifying information of the stationary work point in the work history information of the next waste ST to the position specifying information of the next waste ST, sets the date and time when the waste collection work of the work history information was performed to the current time, stores it in the work history information storage means 57, and transmits the work history information to the management server 1 together with the work vehicle ID of the own vehicle. Further, when special collection point information is generated in steps S141 to S143 described above, the special information transmission means 74 stores the special collection point information in the special collection point information storage means 58 and transmits the special collection point information to the management server 1 together with the work vehicle ID of the own vehicle. Incidentally, the special collection point information and the work history information can also be transmitted 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) transmitted from the in-vehicle terminal device 2 of the work vehicle 4, in step S151, the special information update means 33 determines whether the special collection point information is included. 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 record sub-session.

[0087] Through the above operations, the special collection point information of the garbage ST with special garbage is transmitted from the in-vehicle terminal device 2 of the work vehicle 4 that performs normal garbage collection operations on the normal patrol route to the management server 1, and these special collection point information is accumulated in the special collection point information storage means 18 of the management server 1. And when the normal garbage collection operation on the normal patrol route is completed, all special collection points are determined. In this way, based on the special collection point information accumulated in the special collection point information storage means 18, the commander who operates the management server 1 can efficiently perform the circuit collection of the special garbage discharged to each garbage ST by issuing an instruction regarding the collection of the special garbage.

[0088] (2.3) Operations from special collection route generation to dispatch command Next, based on the special collection point information accumulated in the special collection point information storage means 18 of the management server 1, the system operations until the generation of the special collection route and the issuance of the dispatch command for the special garbage collection operation will be described. Here, two examples will be described: a case where the commander manually issues a dispatch request and a dispatch command, and a case where the management server 1 automatically issues a dispatch request and a dispatch command.

[0089] (2.3.1) Case of manually issuing a dispatch request FIG. 9 is a flowchart showing a special collection route generation and dispatch command process when manually issuing a dispatch request or dispatch command. The special collection route generation and dispatch command process is executed in the management server 1 in parallel with the patrol work session shown in FIG. 6.

[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 in the same manner as 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 stationary work point information storage means 14 is assumed to display each stationary work point (garbage ST) on the map image displayed on the display device 10. Further, the work vehicle information display means 23 is assumed to display 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 in-vehicle terminal device 2 (see steps S144 and S150 in FIG. 7). When receiving the special collection point information from the in-vehicle terminal device 2, in step S161, the management server 1 outputs a special collection point occurrence notification, displays the type of special garbage included in the special information on the display device 10, and displays the position of the generated special collection point on the map image displayed on the display device 10. The "special collection point occurrence notification" refers to a notification for notifying the commander that a special collection point related to a certain type of special garbage has occurred. For example, it is possible to display a notification of the occurrence of a special collection point on the display device 10 or output a notification alarm of the occurrence of a special collection point by an audio output device (not shown). Thereby, the commander can recognize the occurrence of the special collection point and can recognize the type of special garbage placed at the generated special collection point and the position of the special collection point. Based on these pieces of information, the commander can give an instruction to wait for dispatch to the operator who conducts the garbage collection business of the type of special garbage.

[0092] Next, in step S162, the special collection route generation means 34 of the management server 1 determines whether or not the garbage collection operation of the normal tour route (hereinafter referred to as the "observation route") along which the work vehicle 4 equipped with the in-vehicle terminal device 2 that transmitted the special information related to the special collection point notification is traveling has been completed. Here, the determination as to whether or not the garbage collection operation of the normal tour route has been completed is made by referring to the work history information sequentially updated and stored in the work history information storage means 17.

[0093] In step S162, if it is determined that the garbage collection operation of the observation route along which the observation work vehicle is traveling has not been completed, the process returns to step S160, and if it is determined that the operation has been completed, the process proceeds to step S163. When the garbage collection operation of the observation route is completed, the positions of all the 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 are special collection points on the observation route. If there are no special collection points, the special collection route generation and dispatch command issuance process ends, and if there are special collection points, the process proceeds to the next step S164.

[0095] Next, in step S164, the special collection route generation means 34 generates route information for a tour route (special collection route) that tours the stationary work points (garbage ST) where the special garbage of each type K of special garbage is placed, based on the special collection point information (position specifying information of the special collection point and information on the type of special garbage (special 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 from the map information storage means 12. i for each type K i of special garbage.

[0096] Here, at each special collection point on the observation route, if a plurality of types K i (i = 1, 2,..., N k ; N k is the number of types) of special garbage are placed, then for each type K iA special collection route is generated every time. Also, the generation of the tour route is performed based on the road information included in the map information and the location identification information of the special collection point included in each special collection point information. Regarding the method for generating the tour route, a known route generation algorithm (for example, see Non-Patent Document 2) can be used.

[0097] Next, in step S164, the special collection route generation means 34 stores the route information of the special collection route for each item K generated in the special collection route storage means 19. Next, in step S165, the special collection route transmission means 35 refers to the information regarding the work vehicle of each work vehicle 4 stored in the work vehicle information storage means 19a, and for each item K i displays a list of work vehicles that can be dispatched for the garbage collection business (hereinafter referred to as the "dispatchable work vehicle list") for the special garbage of each item K on the display device 10. Thereby, the commander can, by looking at the dispatchable work vehicle list, issue a dispatch request for the garbage collection business of the special garbage of each item K i to each work vehicle 4 in the list. When the dispatch request is accepted, as in FIG. 4, a route transmission request for the route information of the special collection route for item K i is transmitted from the in-vehicle terminal device 2 mounted on the accepted work vehicle 4 to the management server 1, and in response thereto, the special collection route transmission means 35 transmits the route information of the special collection route to the in-vehicle terminal device 2. Thereby, the work vehicle 4 can carry out the garbage collection business of the special garbage of item K i according to the special collection route for item K i and item K i of the special garbage.

[0098] Fig. 10 shows an example of the distribution of each special collection point on the normal tour route when the garbage collection operation on the normal tour route is completed. Fig. 11 shows an example of the special collection route that traverses each special collection point in Fig. 10 generated by the special collection route generation means 34. In Figs. 10 and 11, the garbage ST on the normal tour route is indicated by a square. The garbage ST from which no special garbage is discharged is indicated by a white square (□), and the garbage ST from which special garbage is discharged is indicated by a black square (■). In Fig. 10, the thick line route indicates the normal tour route, and in Fig. 11, the thick line route indicates the special collection route.

[0099] Generally, since special collection points are often sparsely distributed on the normal tour route, it is inefficient to travel along the normal tour route during the special garbage collection operation. On the other hand, in this embodiment, as shown in Fig. 11, the special collection route generation means 34 generates a dedicated tour route (special collection route) for the special garbage collection operation, and the special garbage collection operation is performed along this special collection route, so the operation efficiency will be improved.

[0100] (2.3.2) When automatically issuing a dispatch request and a dispatch command Fig. 12 is a flowchart showing the special collection route generation process on the management server side when automatically issuing a dispatch request and a dispatch command. This special collection route generation and dispatch command process is executed in the management server 1 in parallel with the tour operation session in Fig. 6.

[0101] First, in step S170, the management server 1 determines whether special collection point information has been transmitted from the in-vehicle terminal device 2 (see steps S144 and S150 in Fig. 7). When receiving the special collection point information from the in-vehicle terminal device 2, in step S171, the management server 1 determines the type K of special garbage from the special information included in the special collection point information (position identification information of the special collection point and information on the type of special garbage (special information)). For each type K of special garbage i to identify, for the type K of special garbage i for each, the type K iFor each in-vehicle terminal device 2 of each pre-registered work vehicle 4 that performs the special waste collection service, the item K of the special waste i is transmitted with an identification number (specific item ID) for specifying it and a call standby request Req(K i ). The "call standby request" refers to a command signal that requests waiting for departure for the special waste collection service. Hereinafter, the work vehicle 4 equipped with the in-vehicle terminal device 2 that has transmitted this special collection point information is referred to as an "observation work vehicle", and the normal patrol route along which the observation work vehicle patrols is referred to as an "observation route".

[0102] When a call acceptance application is returned from any in-vehicle terminal device 2 together with the work vehicle ID related to that in-vehicle terminal device 2 in response to the call standby request Req(K i ), in step S172, the management server 1 registers the work vehicle 4 related to the work vehicle ID as a work vehicle (hereinafter referred to as a "commissioned work vehicle") commissioned to perform the waste collection service of item K i and transmits a call reservation registration completed notification to the in-vehicle terminal device 2. Here, the "call acceptance application" refers to a command signal that offers to accept the special waste collection service. The "call reservation registration completed notification" refers to a command signal that notifies that the call acceptance application has been received.

[0103] Then, in step S173, the special collection route generation means 34 of the management server 1 determines whether all the waste collection services on the observation route have been completed. Here, the determination of whether the waste collection service on the normal patrol route has been completed is made by referring to the work history information sequentially updated and stored in the work history information storage means 17. If it is determined that the waste collection service on the observation route along which the observation work vehicle patrols 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 the waste collection service on the observation route is completed, the positions of all the special collection points on the observation route are determined.

[0104] Here, for a certain item K i , once a commissioned work vehicle is registered, thereafter, that item K iFor, the transmission of the activation standby request Req(K i ) in step S171 shall not be performed. Also, when the operations in steps S170 to S173 are completed, there may be a case where there is no acceptance application for activation and no commissioned work vehicle is determined. In that case, either the pre-contracted work vehicle shall be forcibly set as the commissioned work vehicle, or the management server 1 shall output a notification that the consignor is not registered, and for this notification, the commander can separately pre-adjust with the business operator and set the work vehicle to be used as the commissioned work vehicle.

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

[0106] Next, in step S175, the special collection route generation means 34, based on the special collection point information (position identification information of the special collection point and information on the types of special waste (special 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 from the map information storage means 12, for each type K i of special waste, generates route information of a tour route (special collection route) that tours the work points (special collection points) where the special waste of the type K i is discharged.

[0107] Next, in step S176, the special collection route generation means 34 stores the route information of the special collection route for each type K i generated in the special collection route storage means 19, and transmits the route information of the special collection route for each type K i to the commissioned work vehicle registered for each type K i . Next, in step S177, the activation command issuance means 36 issues an activation command C(K i to the commissioned work vehicle of each type K i for which the special collection route transmission means 35 has transmitted the route information of the special collection route, instructing the start of the waste collection operation on the special collection route of the type Ki ) is transmitted, and the special collection route generation and activation command issuance process is terminated.

[0108] Through the above operations, in the management server 1, requests for activation of the garbage collection business on various special collection routes of item K i will be automatically made. Therefore, the labor of the commander is reduced, and the efficiency is improved.

[0109] Fig. 13 is a flowchart showing the activation acceptance process on the in-vehicle terminal device 2 side when the management server 1 automatically issues an activation request.

[0110] Item K i In the in-vehicle terminal device 2 mounted on the work vehicle 4 entrusted with the garbage collection business of special garbage of item K, first, in step S180, when the activation standby request Req(K i )(see step S171) from the management server 1 is received, in step S181, the in-vehicle terminal device 2 displays an activation request acceptance selection button on the display device 50 to prompt the operator to input whether to accept the activation standby request Req(K i ). Here, if the operator makes a selection not to accept by the input device 51, the process returns to step S180. If the operator makes a selection to accept by the input device 51, the process proceeds to the next step S182.

[0111] In step S182, the in-vehicle terminal device 2 transmits an activation acceptance application to the management server 1 together with the work vehicle ID of the work vehicle on which the in-vehicle terminal device 2 is mounted. In response, the in-vehicle terminal device 2 receives an activation reservation registration notice (see step S172) from the management server 1. If the activation reservation registration notice is not received, it is regarded that no activation request has 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) transmitted 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 i Dispatch order C(K) to start garbage collection work on the special collection route i ) (see step S177), the special collection route display means 82 displays the category K on the map displayed on the display device 50. i The special collection route of the special collection point display means 83 displays the special collection point of the item K 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 tour work session described in FIG. 5, and from then on, the process of the tour work session is executed in the same way as in the case of a normal route (step S186).

[0114] Furthermore, in garbage collection work on special collection routes, there is no need to identify special garbage again at each fixed work point (special collection point), so in the case of garbage collection work 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. EXAMPLES

[0115] In the second embodiment, the present invention will be described in the case where it is applied to a garbage collection service using a door-to-door collection method (see Non-Patent Document 1). The "door-to-door collection method" refers to a garbage collection method in which garbage is placed in front of each house (within 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 (refuse truck) that performs garbage collection work collects garbage placed in front of a house while traveling along a set normal patrol route. Therefore, here, the location where garbage is placed (garbage dump) within 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 waste collection work support management system is similar to that of the first embodiment shown in FIG. 1, and therefore will not be described.

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

[0118] The block diagram showing the functional configuration of the vehicle-mounted terminal device 2 is the same as that of Fig. 3 in the first embodiment, and a description of the similar configuration will be omitted. In this embodiment, since there is no fixed work point (garbage ST), the fixed work point information storage means 55 and the fixed work point display means 63 are not used. As described above, in the case of the door-to-door collection method, when the work vehicle 4 has traveled along the normal patrol route, it is deemed that garbage collection work has been carried out in the section of the normal patrol 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] Also, in this embodiment, when the work vehicle 4 is traveling on the normal route during the garbage collection operation, on the display screen of the display device 50, the "stationary work point list" as shown in FIGS. 6 and 8 of Embodiment 1 is not displayed. Instead, a "special collection point list display area" for displaying a list of registered special collection points is displayed. FIG. 14 shows an example of the screen displayed on the display screen of the display device 50 of Embodiment 2. In the "special collection point list display area", rectangular frames (hereinafter referred to as "list item frames") indicating the determined special collection points are displayed in a vertical column. In each list item frame, the position information of the special collection point, the registration number of the special collection point, and the registration time of the special collection point are displayed. Also, in the list item frame below the last registered list item frame, a "next special collection point registration button" for registering the next special collection point is displayed. Also, instead of the "garbage presence / absence input button" in FIGS. 6 and 8 of Embodiment 1, a radio button "left / right road side input button" for selecting whether the special collection point is on the left road side or the right road side in the traveling direction of the normal route is displayed. Also, as shown in FIG. 14, when traveling on the normal route, the "special input area" is always displayed.

[0120] The transmission determination means 75 displays a transmission instruction input area (transmission button) (see FIG. 14) for inputting a transmission instruction for special collection point information on the display device, and outputs a transmission instruction when the transmission instruction input area is selected by an input from the input device 51. Also, when a transmission instruction is output by the transmission determination means 75, the special information transmission means 74 transmits special collection point information including special information which is information on the type of special garbage issued at the work point specified by the item specifying means 73 for the work point at the position determined by the current position measured by the positioning device 52 and position specifying information for specifying the position of the work point to the management server.

[0121] (2) System operation In this embodiment, among the operations of the garbage collection business support management system, the operation of the patrol work session is different from that of the first embodiment. Therefore, below, the operation of the patrol work session in this embodiment will be described.

[0122] FIG. 15 is a flowchart showing the operation of the patrol work session in the garbage collection business support management system of the second embodiment. This patrol work session is a session executed by the in-vehicle terminal device 2 and the management server 1 of the work vehicle 4 when the work vehicle 4 performs garbage collection work at each work point (garbage disposal site within the site of a private house or business facing the road) on the normal patrol route while patrolling the normal patrol route.

[0123] First, in step S200, the in-vehicle terminal device 2 displays on the display device 50 a selection screen for selecting the normal patrol route stored in the patrol route storage means 54, and an operator of the work vehicle 4 equipped with the in-vehicle terminal device 2 selects the normal patrol route R1 for collection by household using the input device 51. When a normal patrol route R1 is selected, in step S201, the map display means 61 displays a map image of the area around the current position measured by the positioning device 52 on the display screen of the display device 50. Further, 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 item specifying means 73 of the in-vehicle terminal device 2 displays a special input area for inputting the item of the special waste put out for the next waste ST on the display screen of the display device 50, and displays a list of special collection points (special collection point list) in the special collection point list display area on the display screen of the display device 50 (see FIG. 14). At this stage, since no special collection points have been registered yet, the special collection point list is an empty list, all list item frames of the special collection point list are set to "unregistered", and a "next special collection point registration button" for registering the next special collection point is displayed in the top list item frame. Further, the item specifying means 73 displays left and right road side input buttons for selecting whether the special collection point is on the left road side or the right road side in the traveling direction of the normal tour route on the display screen of the display device 50. Further, the transmission determination means 75 displays a transmission instruction input area (transmission button) for inputting a transmission instruction for the special collection point information on the display screen of the display device 50.

[0125] Next, in step S203, the trajectory display means 68 acquires the trajectory information of the own vehicle stored in the trajectory information storage means 56, acquires the current position of the own vehicle measured by the positioning device 52, and displays the trajectory of the own vehicle (own vehicle trajectory) and the position of the own vehicle (own vehicle position) on the map displayed on the display screen of the display device 50 (see FIG. 14. In FIG. 14, the own vehicle trajectory is displayed by dot sequence marks, and the own vehicle position is displayed by crosshatch marks).

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

[0127] Here, when an operator boarding the work vehicle 4 discovers that the work vehicle 4 has reached in front of a work point and special waste is placed at the work point, the operator uses the input device 51 (touch panel) to input and set the type of special waste in the special input area (for example, when the type of special waste is "pruning branches", as shown in FIG. 14, the radio button in the pruning branches ([branches]) column of the special input area is set to "yes"). Then, information on whether the work point (special collection point) where special waste is placed is on the left side or the right side in the traveling direction of the normal tour route is input and set from the left / right road side input buttons using the input device 51 (touch panel). After the above settings, the operator uses the input device 51 (touch panel) to select the transmission button (transmission instruction input area) and performs an operation to confirm the special collection point information of the special collection point. Here, as described in the first embodiment, the "special collection point" refers to a work point where special waste is placed on the normal tour route.

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

[0129] Next, in step S206, the special information transmission means 74 determines whether or not any special waste item type is set to "yes" in the special input area. If all special waste item types are "no", the process returns to step S203. If any special waste item type is "yes", then in step S207, the special information transmission means 74 generates special collection point information with the "yes" item type as the special waste item type and the position of the nearest left or right road side of the current position as the position of the special collection point. Here, whether the position of the special collection point is on the left or right road side is determined based on the setting of the left and right road side input buttons.

[0130] Still, as described in the first embodiment, the "special collection point information" is information on a work point where a specific type of waste is discharged, and includes (a) information on the type of special waste (special information) discharged at the work point identified by the item identification means, and (b) position identification information (in this embodiment, position coordinate information) for identifying the position of the work point.

[0131] Next, in step S208, the special information transmission means 74 displays the generated special collection point information in the column of the "next special collection point registration button" in the special collection point list displayed in the special collection point list display area on the display screen of the display device 50 (refer to the list item frame of "confirmed special collection point" in FIG. 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 own vehicle to the management server 1. Next, in step S222, when the management server 1 receives (work vehicle ID, special collection point information) transmitted from the in-vehicle terminal device 2, in step S223, the special information update means 33 stores the received special collection point information in the special collection point information storage means 18.

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

[0134] Also, in parallel with this patrol operation session, the special collection route generation and dispatch command issuance process described in FIG. 9, FIG. 12, or FIG. 13 of Example 1 is executed.

[0135] Through the above operations, special collection point information of work points (special collection points) where special waste is discharged is transmitted from the in-vehicle terminal device 2 of the work vehicle 4 that performs normal waste collection operations on the normal patrol route for household-by-household collection to the management server 1, and these special collection point information are accumulated in the special collection point information storage means 18 of the management server 1. And when the normal waste collection operation on the normal patrol route for household-by-household collection is completed, all the special collection points on the normal patrol route are determined. In this way, based on the special collection point information accumulated in the special collection point information storage means 18, the commander who operates the management server 1 can issue instructions regarding the collection of special waste, enabling the efficient circuit collection of the special waste discharged at each waste ST.

[0136] FIG. 16 shows an example of the distribution of each special collection point on the normal patrol route when the waste collection operation on the normal patrol route for household-by-household collection is completed. FIG. 17 shows an example of a special collection route that circulates through each special collection point in FIG. 16, generated by the special collection route generation means 34 for household-by-household collection. In FIGS. 16 and 17, the waste ST where special waste is discharged is indicated by a square. In household-by-household collection, there is no stationary work point (waste ST), so only the sequentially registered special collection points are sparsely present on the normal patrol route for household-by-household collection. And as shown in FIG. 17, the special collection route generation means 34 generates a dedicated patrol route (special collection route) for the collection operation of special waste, and the collection operation of special waste is carried out along this special collection route, thus improving the work efficiency.

Example

[0137] In Example 1, an example of collecting special collection point information where special waste is discharged for one normal collection route and creating a special collection route was described. In Example 3, an example of collecting special collection point information where special waste is discharged for a plurality of normal collection routes and creating a special collection route will be described.

[0138] In Example 3, it is assumed that in a plurality of normal collection routes, the waste collection operations are carried out in parallel by the work vehicles 4 in charge of their respective normal collection routes. Among these plurality of normal collection routes, two or more normal collection routes (hereinafter referred to as "routes to be integrated") to be integrated when creating one special collection route are denoted as R1(1), …, R1(Nf). Nf is the number of routes to be integrated. Based on each special collection point registered by the waste collection operations in each route to be integrated R1(1), …, R1(Nf), a special collection route R2 is created as a collection route that traverses all of these special collection points.

[0139] It is assumed that the areas where the waste collection operations are carried out by each route to be integrated are close to each other. Integrating normal collection routes that cover distant areas to create a special collection route will lead to a decrease in the operational efficiency of the waste collection operation for special waste.

[0140] Also, the routes to be integrated may be determined in advance, or may be appropriately selected and determined according to the number and distribution of the generated special collection points. Also, the routes to be integrated may be made different according to the type K i of the special waste. This is because the frequency of waste disposal is different depending on the type K i of the special waste, and the distribution density of the special collection points is different for each type K i of the special waste. In this example, for the sake of simplicity, the routes to be integrated will be described as being determined in advance.

[0141] The garbage collection operation support management system of Embodiment 3 has the same overall configuration as that of FIG. 1 in Embodiment 1, the functional configuration of the management server 1 is the same as that of FIG. 2 in Embodiment 1, and the functional configuration of each in-vehicle terminal device 2 is the same as that of FIG. 3 in Embodiment 1. Also, among the operations of the garbage collection operation support management system of Embodiment 3, the operations of the initial setting session and the patrol operation session are the same as those in Embodiment 1 or Embodiment 2. In the garbage collection operation support management system of this embodiment, the operation of the special collection route generation and dispatch command issuance process is different from that in Embodiments 1 and 2.

[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 Embodiment 3. Note that FIG. 18 shows the operation of the management server 1, similar to the case of FIG. 12 in Embodiment 1. Corresponding to the operation of this management server 1, the operation of each in-vehicle terminal device 2 that accepts the dispatch request is the same as that in 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 in-vehicle terminal device 2 of each work vehicle 4 that patrols each integrated target route R1(1),..., R1(Nf). When receiving special collection point information from any of the in-vehicle terminal devices 2, in step S301, the management server 1 identifies the type K of special garbage from the special information included in the special collection point information (position identification information of the special collection point and information on the type of special garbage (special information)), and for each type K of special garbage, it transmits a specific type ID that identifies the type K of special garbage and a dispatch standby request Req(K i to the in-vehicle terminal device 2 of each work vehicle 4 that has been pre-registered to perform the garbage collection operation for the type K of special garbage. i For each type K i of special garbage, to the in-vehicle terminal device 2 of each work vehicle 4 that has been pre-registered to perform the garbage collection operation for the type K of special garbage, it transmits a specific type ID that identifies the type K of special garbage and a dispatch standby request Req(K i ) i .

[0144] When a dispatch acceptance application is returned from any of the in-vehicle terminal devices 2 together with the work vehicle ID related to that in-vehicle terminal device 2 in response to the dispatch standby request Req(K i ), in step S302, the management server 1 designates the work vehicle 4 related to the work vehicle ID as the type K iRegister it as a commissioned work vehicle that commissions the garbage collection service, and send a notification of successful reservation registration to the in-vehicle terminal device 2.

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

[0146] Here, for a certain item K i once a commissioned work vehicle is registered, thereafter, for that item K i the transmission of the standby request for dispatch Req(K i ) in step S301 shall not be performed. Also, when the operations in steps S300 to S303 are completed, there may be a case where there is no application for acceptance of dispatch and no commissioned work vehicle is determined. In that case, either force the pre-contracted work vehicle to be the commissioned work vehicle, or the management server 1 outputs a notification of unregistered consignor, and for this notification, the commander can separately pre-adjust with the operator and set the work vehicle to be the commissioned work vehicle.

[0147] Next, in step S304, the special collection route generation means 34 determines whether or not there is a special collection point on any of the integrated target routes R1(1), …, R1(Nf). If not, the special collection route generation and dispatch command issuance process ends. If there is, the process 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 based on the extracted special collection point information (position specifying information of the special collection point and information on the types of special waste (special information)) and the map information read from the map information storage means 12, for each type K i of the special waste, route information of a tour route (special collection route) that tours the work points (special collection points) where the special waste of that type K i is put out is generated.

[0149] Next, in step S306, the special collection route generation means 34 stores the route information of the special collection route for each type K i generated in the special collection route storage means 19, and transmits the route information of the special collection route for each type K i to the commissioned work vehicle registered for that type K i . Next, in step S307, the deployment order issuing means 36 issues a deployment order C(K i ) to the commissioned work vehicle of each type K i for which the special collection route transmission means 35 has transmitted the route information of the special collection route, instructing the start of the waste collection operation on the special collection route of that type K i , and ends the special collection route generation / deployment order issuing process.

[0150] FIG. 19 is a diagram showing two integration target routes R1(1) and R1(2) to be integrated and an example of special collection points registered on these 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, the work points (special collection points) where special waste is discharged are indicated by quadrilaterals. 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 present on these routes. Since the areas covered by the integration target routes R1(1) and R1(2) are close to each other, the special collection points existing on these routes will be distributed within a relatively concentrated area. Therefore, the special collection route generation means 34 generates a dedicated circuit route (special collection route) for the collection operation of special waste as shown in FIG. 20 so as to cover all the special collection points distributed within such a relatively concentrated area.

[0151] As described above, in the waste collection operation support management system of this embodiment, by integrating each special collection point on a plurality of integration target routes R1(1),..., R1(Nf) to generate one special collection route, it is possible to perform the waste collection operation for the special collection points distributed within a relatively concentrated area with one special collection route. Therefore, it is possible to further improve the operational efficiency of the special waste collection operation.

Embodiment

[0152] In Examples 1 and 2, when generating one special collection route from the special collection points occurring on one normal circuit route, an example was described in which the activation command for the waste collection operation of the special collection route is issued after all the waste collection operations on the normal circuit route are completed. However, in Example 4, an example will be described in which the activation command for the waste collection operation of the special collection route is issued without waiting for the completion of the waste collection operation on the normal circuit route, before the waste collection operation on the normal circuit route is completed.

[0153] (1) Basic concept In the fourth embodiment, without waiting for the completion of the regular route patrol work, a special collection route is generated and a dispatch order is issued. As a result, the waiting time until the commissioning vehicle is dispatched is shortened, so the efficiency of the special waste collection service is further improved. However, in this case, it is assumed that information on the work points (special collection points) where special waste has been issued later is transmitted to the management server 1 in the section of the regular route where the waste collection service is not completed at the time of issuing the dispatch order. Therefore, in this case, it is necessary to update the special collection route additionally during the special waste collection service on the special collection route for which the dispatch order has been issued.

[0154] FIG. 21 is a diagram showing the states of the regular route R1 and the special collection route R2(t) at the time t when the waste collection service of the regular route R1 is not completed. In FIG. 21, (a) shows the state of the regular route R1 at a certain time t when the waste collection service is not completed, and (b) shows the state of the special collection route R2(t) generated based on the special collection points determined on the regular route R1 at time t. In FIG. 21, the route start point of the regular route R1 is indicated by a black square (■), and the route end point is indicated by a white square (□). The position of the special collection point is indicated by a cross (×), and the position q1(t) of the work vehicle B1 performing the waste collection service on the regular route R1 at time t is indicated by a dotted point (a black dot in a circle).

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

[0156] The travel time (the time required to move between two points) estimate T1(t) for this work vehicle B1 to move while performing garbage collection operations from the current position q1(t) to the route end point 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 performing garbage collection operations on the normal circuit route R1 in the past, which is stored in the trajectory information storage means 15. For example, if the average value of the travel time from the current position q1(t) to the route end point obtained from the movement trajectory is E(T1) and the standard deviation is σ(T1), 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%, then α = 1.96).

[0157] Also, based on the special collection points P1,..., P determined at time t Np If the special collection route generated by the special collection route generation means 34 based on this is the determined special collection route R2(t), the starting 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 becomes. The estimated value T2(t) of the travel time of the work vehicle B2 when performing garbage collection operations for special garbage on this determined special collection route R2(t) is called the "determined special collection route estimated travel time". Regarding the determined special collection route estimated travel time T2, if the average moving speed v2 of the determined special collection route R2 is set to an appropriate value (for example, the average moving speed statistically obtained from the movement trajectory during past garbage collection operations for special garbage), it can be calculated based on the course distance of the determined special collection route R2(t) 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, while the work vehicle B2 is performing the special waste collection operation along the determined special collection route R2(t) at time t, all the waste collection operations on the normal patrol route R1 by the work vehicle B1 are completed. During this period, it is estimated that all the additional special collection points from the current position q1(t) on the normal patrol route R1 to the route end point are determined. Therefore, when the condition T1(t) ≤ T2(t) is satisfied, a dispatch command may be sent from the management server 1 to the in-vehicle terminal device 2 of the work vehicle B2. The condition for determining the timing of sending such a dispatch command from the management server 1 to the in-vehicle terminal device 2 of the work vehicle B2 is called the "dispatch command issuance condition".

[0159] Furthermore, when the current position q2 of the work vehicle B2 at time t is known, the movement route and the required time T20(t) from the current position q2(t) of the work vehicle B2 to the start point P1 of the determined special collection route R2(t) can be calculated by a route calculation algorithm used in a normal car navigation device or the like. Therefore, in this case, the dispatch command issuance condition can be set as T1(t) ≤ T2(t) + T20(t), and the dispatch command can be issued earlier.

[0160] After the issuance of the dispatch command, when all the waste collection operations on the normal patrol route R1 by the work vehicle B1 are completed, all the additional special collection points from the position q1(t) on the normal patrol route R1 to the route end point are determined. At this time, the special collection route generation means 34 Np uses the special collection point P as the starting point and generates an additional special collection route (hereinafter referred to as the "remaining special collection route") R2'(t) passing through all the additional special collection points, and the route information of the additional special collection route may be transmitted to the work vehicle B2. Thereby, when the work vehicle B2 reaches the end point P Np of the determined special collection route R2(t), it can immediately shift to the special waste collection operation on the remaining special collection route R2'(t).

[0161] (2) Configuration and operation The garbage collection operation support management system of Example 4 has the same overall configuration as that of FIG. 1 in Example 1, and the functional configuration of each in-vehicle terminal device 2 is the same as that of FIG. 3 in Example 1. Also, among the operations of the garbage collection operation support management system of Example 4, the operations of the initial setting session and the patrol operation session are the same as those in Example 1 or Example 2. In the garbage collection operation support management system of this example, the functional configuration of the management server 1 is partially different from that in Examples 1 and 2, and the operation of the special collection route generation and dispatch order issuance process is partially different from that in Examples 1 and 2.

[0162] FIG. 22 is a block diagram showing the functional configuration of the management server 1 in the garbage collection operation support management system of Example 4. In FIG. 22, for the components having the same configuration as those in FIG. 2, the same reference numerals are given and the description thereof is omitted. Compared with FIG. 2, in the management server 1 of this example, a remaining travel time estimation means 40, a determined special route travel time estimation means 41, a starting point arrival travel time estimation means 42, and a remaining special collection route transmission means 43 are added.

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

[0164] The determined special route travel time estimation means 41 is for each type K i of special garbage, based on the special collection point information on the normal patrol route R1 that the work vehicle B1 is patrolling and stored in the special collection point information storage means 18 up to the current time, generates route information of the determined special collection route R2(K i ) by the special collection route generation means 34, and calculates a determined special collection route estimated travel time T2(K i ) related to the determined special collection route R2(K i ).

[0165] The starting point arrival travel time estimation means 42 is from the current position of the work vehicle B2(K i ) that commissions the garbage collection operation on the determined special collection route R2(K i ) to the determined special collection route R2(Ki ) to the starting point, the estimated time T20(K i ) required for the work vehicle B2(K i ) to move is calculated.

[0166] is The dispatch command issuing means 36 determines the dispatch command issuing conditions for each type K i of the special waste, and issues a dispatch command C(K i ) to the work vehicle B2(K i ).

[0167] After the remaining special collection route transmission means 43 transmits the dispatch command C(K i ), the special collection route generation means 34 generates the remaining special collection route R2’(K i ) of the confirmed special collection route R2(K i ) related to the dispatch command C(K i ), and transmits it to the work vehicle B2(K i ).

[0168] Fig. 23 is a flowchart showing the special collection route generation / dispatch command issuing process of the management server in the waste collection business support management system of Example 4. Here, for simplicity of explanation, the number of types of special waste is one type (only type K1), and the subscript “(K1)” is omitted.

[0169] First, in steps S400 to S402, the management server 1 performs processes of requesting standby for dispatch and registering business entrustment with the in-vehicle terminal device 2 of the work vehicle entrusted with special waste. Since this is the same as steps S170 to S172 in Fig. 12 of Example 1, the description is omitted. Here, the work vehicle 4 for which business entrustment has been registered is taken as the entrusted work vehicle B2.

[0170] Next, in step S403, the definite 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 tour route R1 is received from the work vehicle B1 traveling on the normal tour route R1 and registered in the special collection point display means 24 (one or more special collection points are determined on the normal tour 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 definite special route travel time estimation means 41 acquires the special collection point information on the normal tour route R1 determined at the current time t from the special collection point information storage means 18, and generates the route information of the definite special collection route R2(t) by the special collection route generation means 34. Further, when the commissioned work vehicle B2 is registered in step S402, the starting point arrival travel time estimation means 42 generates the route information from the current position q2(t) of the commissioned work vehicle B2 sent from the in-vehicle terminal device 2 of the commissioned work vehicle B2 to the starting point of the definite special collection route R2(t).

[0172] Next, in step S405, the definite special route travel time estimation means 41 calculates the estimated travel time T2(t) of the definite special collection route of the special collection route R2(t). Further, 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 normal tour route R1. Further, when the commissioned 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 the estimated value of the travel time from the current position q2(t) of the commissioned work vehicle B2 to the starting point of the definite special collection route R2(t).

[0173] Next, in step S406, the dispatch command issuing means 36 determines whether or not the dispatch command issuing condition T1(t) ≤ T2(t) (when T20 is 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 or not all the garbage collection operations on the normal tour route R1 have been completed. If the garbage collection operations on the normal tour route R1 have not been completed, the process returns to step S400. If the garbage collection operations on the normal tour route R1 have been completed, since there are no special collection points on the normal tour route R1, the special collection route generation / dispatch command issuing process ends.

[0175] Next, in step S408, the special collection route transmission means 35 transmits the route information of the determined special collection route R2(t) generated in step S404 to the in-vehicle terminal device 2 of the commissioned work vehicle B2. Next, in step S409, the dispatch command issuing means 36 transmits a dispatch command C(K1) instructing the start of the garbage collection operation on the determined special collection route R2(t) to the in-vehicle terminal device 2 of the commissioned work vehicle B2. Thereby, the garbage collection operation of the special garbage on the determined special collection route R2(t) by the commissioned work vehicle B2 is started.

[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 that is continuously updated in the trajectory information storage means 15 by the trajectory information updating means 31, and waits until the garbage collection operation on the normal tour route R1 is completed.

[0177] When the garbage collection operation on the normal tour 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 transmitted to the end point of the normal tour route R1 (hereinafter referred to as "remaining normal tour 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 tours all the special collection points on the remaining normal tour route R1', and transmits it to the in-vehicle terminal device 2 of the commissioned work vehicle B2. As a result, when the commissioned work vehicle B2 reaches the end point of the determined special collection route R2(t), it can continue to perform the garbage collection operation for special garbage on the remaining special collection route R2'(t).

Embodiment

[0178] In Embodiment 5, another example of early issuing the dispatch command for the garbage collection operation on the special collection route before the completion of the garbage collection operation on the normal tour route will be described. In Embodiment 4, as a basic case of early issuing the dispatch command, the case of generating one special collection route based on the special collection points on one normal tour route was described. In this embodiment, a method applicable to the case of generating one special collection route based on the special collection points on a plurality of normal tour routes will be described.

[0179] In Embodiment 3, after the garbage collection operation was completed for all of the normal tour routes (routes to be integrated) that form the basis for creating the special collection route, the special collection route was generated and the dispatch command was issued. However, in Embodiment 5, the special collection route is generated and the dispatch command is issued without waiting for the completion of the garbage collection operation for all the routes to be integrated. As a result, the waiting time of the commissioned work vehicle that performs the garbage collection operation on the special collection route is shortened, so the working efficiency of the garbage collection operation for special garbage is improved.

[0180] However, in this case, it is assumed that in the section of the integrated target route where the garbage collection work is not completed at the time of issuing the dispatch command, information on the special collection points is subsequently transmitted to the management server 1. Therefore, in this case, it is necessary to add and update the special collection route during the garbage collection work of the special garbage on the special collection route for which the dispatch command has been issued.

[0181] (1) Basic concept When integrating the special collection points on multiple integrated target routes, when generating the special collection route, since the positional relationship of each special collection point is also affected, it is not possible to issue a dispatch command simply by comparing only the estimated travel time as in Example 4. Therefore, in order to incorporate the positional relationship of each special collection point, the area covered by the integrated target routes to be integrated is divided into a plurality of zones, and for each zone, the time when the garbage collection work within the zone is completed is estimated, and a determination is made as to whether to issue a dispatch command.

[0182] First, let the integrated target routes to be integrated be R1(1), …, R1(Nf). Nf is the number of integrated target routes and is an integer of 1 or more. The area covered by all the integrated target routes R1(1), …, R1(Nf) is divided into a plurality of zones, and each zone is Z1, Z2, …, Z Nz Let Nz represent the number of zones.

[0183] Fig. 24 shows an example of dividing the area covered by the integrated target routes into a plurality of zones. In this example, the area covered by two integrated target routes R1(1) and R1(2) is divided into four zones Z1, Z2, Z3, and Z4. The integrated target route R1(1) is shown by a thick dashed line, and the integrated target route R1(2) is shown by a thick solid line. Also, the current positions of the work vehicles B1(1) and B1(2) performing garbage collection work on the integrated target routes R1(1) and R1(2) are shown by crosshatch points, and the traveling directions of the work vehicles B1(1) and B1(2) are shown by arrows.

[0184] In FIG. 24, the work vehicle B1(1) is within zone Z3, and the work vehicle B1(2) is within zone Z4. The waste collection operations for all the integrated target routes R1(1) and R1(2) in zones Z1 and Z2 have been completed. In this way, when the waste collection operations for all the integrated target routes within a zone have been completed, that zone is called a "completed work zone". If there is even one integrated target route within a zone for which the waste collection operation has not been completed, that zone is called an "uncompleted work zone". In FIG. 24, zone Z3 is an uncompleted work zone because the waste collection operation for the integrated target route R1(2) has been completed, but the waste collection operation for the integrated target route R1(1) has not been completed. Zone Z4 is an uncompleted work zone because the waste collection operations for both of the integrated target routes R1(1) and R1(2) have not been completed.

[0185] Also, in FIG. 24, the special collection points (confirmed special collection points) for which the special collection point information has been transmitted to and registered with the management server 1 by the work vehicles B1(1) and B1(2) are indicated by a cross mark (×). The special collection points (unconfirmed special collection points) that the work vehicles B1(1) and B1(2) have not yet passed through and are not registered with the management server 1 are indicated by a triangle mark (△). The unconfirmed special collection points are the special collection points that are scheduled to be confirmed when the work vehicles B1(1) and B1(2) pass through them later.

[0186] When a certain zone Z k changes from an uncompleted work zone to a completed work zone, all the special collection points within zone Z k are confirmed at that time. In this way, a zone that newly changes from an uncompleted work zone to a completed work zone at a certain time t is called a "new zone" at time t. Therefore, every time a new zone Z k occurs at each time t, a special collection route that tours the confirmed special collection points within all the completed work zones Z1 to Z k at time t is constructed on a zone-by-zone basis.

[0187] At a certain time t, when zone Z itransitions from the work-incomplete zone to the work-completed zone, and at this time, zones Z1 to Z k is the work-completed zone, zone Z k+1 ~Z Nz is assumed to be the work-incomplete zone. At this time, the special collection route generation means 34 generates a special collection route (hereinafter referred to as the "determined special collection route") R2(t) that tours all the special collection points within zones Z1 to Z k . Then, the estimated value of the travel time required for the work vehicle B2 to move while performing the garbage collection operation along the determined special collection route R2 is defined as the determined special collection route estimated travel time T2(t). Also, at this time, the estimated remaining travel times (refer to Example 4) in the respective integrated target routes R1(1),..., R1(Nf) are denoted as T1(1;t),..., T1(Nf;t), and the maximum value of these is defined as the estimated normal tour completion time T1(t) (T1(t) = max(T1(1;t),..., T1(Nf;t))).

[0188] Fig. 25 shows an example of the special collection route R2(t) that tours all the special collection points within the work-completed zones Z1 and Z2 determined at the time of Fig. 24, and the special collection route R2(t) + R2’(t) that tours all the special collection points within all the zones Z1 to Z4.

[0189] Here, if the condition T1(t) ≤ T2(t) is satisfied, while the work vehicle B2 performs the garbage collection operation for special garbage along the determined special collection route R2(t) determined at time t, the garbage collection operations by the work vehicles B1(1),..., B1(Nf) on each of the integrated target routes R1(1),..., R1(Nf) are all completed. During this period, it is estimated that all the undetermined special collection points at time t on each of the integrated target routes R1(1),..., R1(Nf) are determined and become determined special collection points. Therefore, when the condition T1(t) ≤ T2(t) is satisfied, it is sufficient to send a departure command from the management server 1 to the in-vehicle terminal device 2 of the work vehicle B2. The condition for determining the timing of sending such a departure command from the management server 1 to the in-vehicle terminal device 2 of the work vehicle B2 is called the "departure command issuance condition".

[0190] Furthermore, when the current position q2 of the work vehicle B2 at time t is known, the movement route and the required time T20(t) from the current position q2(t) of the work vehicle B2 to the start point of the determined special collection route R2(t) can be calculated by a route calculation algorithm used in a normal car navigation device or the like. Therefore, in this case, the activation command issuance condition can be set as T1(t) ≦ T2(t) + T20(t), and the activation command can be issued earlier.

[0191] After the issuance of the activation command, when all the garbage collection operations on the respective integration target routes R1(1), …, R1(Nf) by the work vehicles B1(1), …, B1(Nf) are completed, the special collection route generation means 34 sets the end point of the determined special collection route R2(t) as the start point, and all additional special collection points (special collection points within the zones Z i+1 ~Z Nz It is only necessary to generate an additional special collection route (hereinafter referred to as the “remaining special collection route”) R2’(t) that passes through the special collection points) and transmit the route information of the additional special collection route to the work vehicle B2. Thereby, when the work vehicle B2 reaches the end point of the determined special collection route R2(t), it can immediately shift to the special garbage collection operation on the remaining special collection route R2’(t).

[0192] (2) Configuration and operation The garbage collection operation support management system of Example 4 has the same overall configuration as that of FIG. 1 in Example 1, and the functional configuration of each in-vehicle terminal device 2 is the same as that of FIG. 3. Also, among the operations of the garbage collection operation support management system of Example 5, the operations of the initial setting session and the patrol operation session are the same as those in Example 1 or Example 2. In the garbage collection operation support management system of this example, the functional configuration of the management server 1 is partially different from that of FIG. 2, and the operation of the special collection route generation / activation command issuance process is partially different from that of Example 3.

[0193] FIG. 26 is a block diagram showing the functional configuration of the management server 1 in the garbage collection operation support management system of Example 5. In FIG. 26, for the same components as in FIG. 2, the same reference numerals are given and the description thereof is omitted. Compared with FIG. 2, in the management server 1 of this embodiment, a remaining travel time estimation means 40, a determined special route travel time estimation means 41, a starting 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 round-trip completion time estimation means 45 are added.

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

[0195] The work completion zone determination means 44, based on the trajectory information transmitted from the in-vehicle terminal device 2 mounted on the work vehicle B1(j) that tours each integrated target route R1(j) (j = 1,..., Nf), for each zone Z k (k = 1,..., Nz), determines whether or not the zone Z k is a work completion zone.

[0196] The determined special route travel time estimation means 41, for each type K i of special garbage, based on the special collection point information of the special collection points within the work completion zone among the special collection points on the integrated target route R1(j) that each work vehicle B1(j) (j = 1,..., Nf) is touring and stored in the special collection point information storage means 18 up to the current time, generates route information of the special collection route R2 by the special collection route generation means 34, and calculates a determined special collection route estimated travel time T2 regarding the special collection route R2.

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

[0198] Generally, 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, for each integrated target route R1(j) (j = 1, …, Nf), the remaining travel time calculation means 40 calculates the estimated remaining travel time T1(j) for the integrated target route R1(j), and calculates the estimated normal tour completion time T1, which is the maximum value of the Nf calculated estimated remaining travel times T1(1), …, T1(Nf).

[0199] The dispatch order issuing means 36 determines the dispatch order issuing conditions for each type K i of special waste, and transmits the dispatch order C(K i ) to the work vehicle B2.

[0200] After transmitting the dispatch order C(K i ), the remaining special collection route transmission means 43 generates the remaining special collection route R2’ of the special collection route R2 related to the dispatch order C(K i ) by the special collection route generation means 34, and transmits it to the work vehicle B2.

[0201] FIG. 27 is a flowchart showing the special collection route generation / dispatch order issuing process of the management server in the waste collection business support management system of the fifth embodiment. Here, for simplicity of explanation, the number of types of special waste is set to one type (only type K1), and the subscript “(K1)” is omitted.

[0202] First, in steps S500 to S502, the management server 1 performs processes of requesting standby for dispatch and registering business entrustment with the in-vehicle terminal device 2 of the work vehicle that entrusts special waste. Since this is the same as steps S170 to S172 in FIG. 12, the description is omitted. Here, the work vehicle 4 for which business entrustment has been registered is set as the entrusted work vehicle B2.

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

[0204] Next, in step S504, the definite special route travel time estimation means 41, based on the special collection point information of the special collection points on the integrated target route R1(j) (j = 1, …, Nf) traveled by each work vehicle B1(j) stored in the special collection point information storage means 18 up to the current time, among which the special collection points within the work completion zones Z1 to Z k generates the route information of the special collection route (definite special collection route) R2(t) by the special collection route generation means 34 based on the special collection point information of the special collection points within. Also, when the commissioned work vehicle B2 is registered in step S402, the start point arrival travel time estimation means 42 generates the route information from the current position q2(t) of the commissioned work vehicle B2 to the start point of the definite special collection route R2(t) sent from the in-vehicle terminal device 2 of the commissioned work vehicle B2.

[0205] Next, in step S505, the definite special route travel time estimation means 41 calculates the definite special collection route estimated travel time T2(t) of the definite special collection route R2(t) generated in step S504. Also, when the commissioned 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 the estimated value of the travel time from the current position q2(t) of the commissioned work vehicle B2 to the start 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 whether there is a work completion zone among all the zones Z1, Z2, …, Z Nz at the current time t. If there is no work completion zone, proceed to step S509; if there is, proceed to the next step S507.

[0207] Next, in step S507, the remaining travel time estimation means 40 acquires the current positions of the respective work vehicles 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 the work vehicle B1(j) to the end point of the normal circuit route R1(j). Then, the normal circuit completion time estimation means 45 calculates the estimated normal circuit completion time T1(t), which is the maximum value of the Nf calculated estimated remaining travel times T1(1;t), …, T1(Nf;t).

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

[0209] Next, in step S509, the management server 1 determines whether or not the garbage collection operations for all the integrated target routes R1(1), …, R1(Nf) have been completed. If the garbage collection operations for all the integrated target routes R1(1), …, R1(Nf) have not been completed, the process returns to step S500. If the garbage collection operations for all the integrated target routes R1(1), …, R1(Nf) have been completed, since there are no special collection points on the integrated target routes R1(1), …, R1(Nf), the special collection route generation / dispatch order issuing process ends.

[0210] Next, in step S510, the special collection route transmission means 35 transmits the route information of the determined special collection route R2(t) generated in step S504 to the in-vehicle terminal device 2 of the consigned work vehicle B2. Then, in step S511, the dispatch order issuing means 36 transmits a dispatch order C(K1) instructing the start of the garbage collection operation on the determined special collection route R2(t) to the in-vehicle terminal device 2 of the consigned work vehicle B2. Thereby, the garbage collection operation of the special garbage on the determined special collection route R2(t) by the consigned work vehicle B2 is started.

[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 the garbage collection operations for all the integrated target routes R1(1), …, R1(Nf) are completed.

[0212] When the garbage collection operations for all the integrated target routes R1(1), …, R1(Nf) are completed, in step S513, the remaining special collection route transmission means 43 determines whether there is a special collection point within the unfinished work zone at the time t when the dispatch command C(K1) was transmitted. If there is a special collection point, 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 determined special collection route R2(t) and tours all the special collection points within the unfinished work zone at the time t, and in step S515, transmits it to the in-vehicle terminal device 2 of the commissioned work vehicle B2. As a result, when the commissioned work vehicle B2 reaches the end point of the determined special collection route R2(t), it can continue to perform the garbage collection operation for special garbage on the remaining special collection route R2’(t).
