Description

  The present invention relates to a transportation vehicle operation that provides transportation route information from the operation management center to each transportation vehicle when a plurality of transportation vehicles carry between one or more loading places and one or more loading places. The present invention relates to a support system and a transportation vehicle operation support method.

  A system for providing transportation route information between a loading place and a loading / unloading place from an operation management center has been developed for a dump truck that carries earth and sand. When providing transportation route information, it is important to determine an optimal transportation route so that transportation time does not become long due to traffic jams or traffic restrictions (and so that transportation amount does not decrease). Real-time information is important for such road condition information such as traffic jams and traffic restrictions. Probe cars are used to collect road condition information in real time. For example, the center collects road condition information from a large number of probe cars, provides real-time road condition information from the center to each car, and each car re-searches the route to the destination when the real-time road condition information changes. To do. In the traffic information providing system described in Patent Document 1, when an automobile occupant inputs traffic information data, the in-vehicle computer of the in-vehicle device transmits the traffic information data including the current position information to the information center via the automobile phone. Then, when the traffic information data is received, the information server stores the traffic information data in the traffic information database, and when there is a transmission request from an in-vehicle computer of any car, the traffic information data in the corresponding area is searched from the traffic information database. The traffic information data is transmitted to the car.

  As described above, a technique for re-searching a route to a destination using real-time information collected by a probe car is mainly used in general passenger cars. In the case of a general passenger car, one destination is determined, and traveling ends when the destination is reached. Therefore, it is only necessary to set an optimum route until the destination is reached. However, when transporting earth and sand with a dump truck, it goes back and forth between the loading place and the unloading place many times a day. Since road conditions such as traffic jams and traffic restrictions constantly change during the day, if the transportation route is not changed accordingly, the transportation time becomes longer and the transportation amount per unit time decreases. Furthermore, when transporting between multiple loading locations and multiple unloading locations with a large number of dump trucks, each dump truck is assigned a loading location and a loading location and transported according to changing road conditions. Providing each route is very difficult.

  Accordingly, the present invention provides a transport vehicle operation that provides optimal transport route information to each transport vehicle when a plurality of transport vehicles transport between one or more loading locations and one or more loading locations. It is an object to provide a support system and a transportation vehicle operation support method.

  The transportation vehicle operation support system according to the present invention provides a transportation route from an operation management center to each transportation vehicle when a plurality of transportation vehicles carry between one or more loading places and one or more loading places. A transport vehicle operation support system for providing information, wherein the transport vehicle includes position acquisition means for acquiring position information during traveling, road condition acquisition means for acquiring road condition information during travel, and road condition acquisition means. When the road condition information is acquired, the vehicle side transmission means for transmitting the road condition information to the operation management center in association with the position information acquired by the position acquisition means, and the transport route information transmitted from the operation management center are received. A vehicle-side receiving means, and the operation management center includes a center-side receiving means for receiving road condition information associated with position information transmitted from the transport vehicle, and a combination of a loading place and an unloading place. In order to travel the transportation route based on the road condition information in which a plurality of transportation routes are set for each combination and the positional information received by the center side reception device is associated with each transportation route set by the route setting device. A required time calculating means for calculating the required time, a selecting means for selecting a transport route for each transport vehicle based on the required time for each transport route calculated by the required time calculating means, and transport route information selected by the selecting means. Center-side transmitting means for transmitting to each transport vehicle is provided.

  This transportation vehicle operation support system is a system that provides transportation route information to a plurality of transportation vehicles (for example, dump trucks, trucks) from an operation management center. There are one or more loading places where the transporting vehicle loads the transported goods (for example, earth and sand, construction materials), and there are also one or more loading / unloading places where the transported goods are unloaded. There are a plurality of transportation routes between any loading place and any loading / unloading place. Each transport vehicle functions as a probe car, and transport route information including information on loading places and unloading places is provided from the operation management center. The operation management center collects road condition information from each transport vehicle and provides transport route information to each transport vehicle. The road condition information includes various information that affects the travel time required for the transportation route, and includes, for example, traffic jam information, traffic regulation information (one-side lane travel information, road surface damage information, fallen object information, and closed information). .

  In each transport vehicle, position information during traveling is acquired by position acquisition means. Further, in each transport vehicle, road condition information during traveling is acquired by road condition acquisition means. This road condition acquisition means may be a means for an occupant (driver) of a transport vehicle to input road condition information, or information detected by various on-vehicle sensors (for example, image analysis of an image taken by a camera). It is also possible to obtain the information from the information detected by the vehicle speed change information detected by the vehicle speed sensor. In each transport vehicle, when the road condition acquisition means acquires real-time road condition information, the vehicle-side transmission means associates the road condition information with traveling position information and transmits it to the operation management center.

  In the operation management center, every time road condition information associated with position information is transmitted from an arbitrary transport vehicle, the road condition information is received by the center side receiving means. In the operation management center, a plurality of transportation routes are set for each combination of loading place and unloading place by route setting means. In the operation management center, the required time for traveling along the transportation route is calculated based on real-time road condition information for a plurality of transportation routes for each combination by the required time calculation means. For example, when there is no road condition information that affects the required time on the transportation route, the standard speed at which the transportation vehicle can travel (the speed considering the speed limit on the transportation route, normal traffic volume, traffic lights, etc.) Based on the above, the standard required time is calculated. When there is road condition information that affects the required time on the transport route, the required time is calculated by adding the time required for traffic congestion or traffic restrictions included in the road condition information to the standard required time of the transport route. Further, the operation management center selects the transport route of each transport vehicle based on the required time of each transport route by the selection means. Here, basically, the transportation route with the shortest required time is selected, but the number of vehicles to be loaded and unloaded at the loading place, the loading place, the loading capacity at the loading place, and the unloading capacity at the loading place. In some cases, the second shortest transportation route, the third shortest transportation route, or the like is selected. In addition, since the place of the both ends of a conveyance route becomes a loading place and a loading / unloading place, the information on a loading place and a loading place is contained in a conveyance route.

  In the operation management center, the transport route information is transmitted to each transport vehicle by the center side transmission means. In each transport vehicle, transport route information is received by the vehicle side receiving means. Each transport vehicle travels between the loading place and the unloading place according to the received transport route information. Incidentally, when the real-time road condition information from each transport vehicle changes, the transport route selected by the selection means may change because some transport routes may change the required time. In this case, the changed transport route is transmitted to each transport vehicle, and each transport vehicle travels between the loading place and the unloading place according to the changed transport route information.

  This transport vehicle operation support system calculates the required time for multiple transport routes for each combination of loading and unloading locations based on real-time road condition information collected from transport vehicles, and the required time for each transport route. By selecting the transport route of each transport vehicle based on the above, it is possible to provide optimal transport route information for a plurality of transport vehicles. In this way, since a transport route with a short required time is selected for each transport vehicle, the transport amount per unit time in each transport vehicle increases, and the transport amount that can be transported as a whole system becomes very large. Further, since real-time road condition information can be collected from each transport vehicle, it can be changed to a transport route whose required time is shortened in real time according to changes in the road condition information.

  In the transport vehicle operation support system of the present invention, the operation management center is based on the required time calculated by the required time calculation means, the transport distance of the transport route, and the transport amount of the transport vehicle for each transport route set by the route setting means. It is preferable that a transportation capacity calculation means for calculating transportation capacity per unit time by one transportation vehicle is provided, and the selection means preferably selects a transportation route based on the transportation capacity of each transportation route calculated by the transportation capacity calculation means. It is.

  In the operation management center, each transport route is calculated by the transport capacity calculation means based on the required time considering real-time road condition information on the transport route, the transport distance of the transport route, and the transport amount of the transport vehicle. Calculate the carrying capacity per unit time by vehicle. Since the transport distance of each transport route and the transport amount of the transport vehicle are fixed values, the transport capacity per unit time by one transport vehicle changes according to the required time of the transport route. The carrying capacity becomes high (the carrying quantity increases). Therefore, the operation management center selects the transport route of each transport vehicle by the selection means based on the transport capability of each transport route. Here, basically, the route with the highest carrying capacity is selected, but the number of vehicles dispatched to the loading place and unloading place, the loading capacity at the loading place, and the unloading capacity at the loading place. In some cases, the second highest transportation capacity, the third highest transportation route, etc. are selected.

  In the transport vehicle operation support system of the present invention, it is preferable that the selection means change the transport route based on the loading capacity of each loading place and / or the loading capacity of each loading place.

  If a transport route with the shortest travel time (or a transport route with the highest transport capacity) is selected, and a large number of transport vehicles are dispatched to any loading or unloading location, It may exceed the loading capacity or the loading / unloading capacity of the loading / unloading location. In such a case, the required time during transportation of each transport vehicle is shortened, but the waiting time at the loading place or unloading place is lengthened, and as a result, the transport amount of the entire system is reduced. Therefore, in the operation management center, the transportation route is changed based on the loading capacity of each loading place and / or the loading capacity of each loading place by the selection means. In this way, in this transportation vehicle operation support system, by changing the transportation route based on the loading capacity of the loading place and the loading capacity of the loading place, the loading capacity and loading place of the loading place are changed. The transport route of each transport vehicle can be determined so as not to exceed the unloading capacity, the waiting time at the loading place and the unloading place can be suppressed, and the decrease in the transport amount as a whole system can be suppressed.

  In the transportation vehicle operation support system according to the present invention, the operation management center determines the number of vehicles to be delivered to each loading place based on the loading ability of each loading place, or loads each loading place. It is provided with a dispatch number determining means for determining the number of dispatched vehicles to each unloading location based on the wholesale capacity, and the selection means is the number of dispatched vehicles or the unloading location for each loading place determined by the dispatch number determining means. It is preferable to select a transportation route based on the number of vehicles allocated for each vehicle.

  If more vehicles than the loading capacity at the loading location are dispatched or more vehicles than the loading capacity at the loading location are dispatched, the waiting time at the loading location or loading location become longer. Therefore, in the operation management center of this transportation vehicle operation support system, the number of dispatched vehicles is determined by the number of dispatched vehicles determining means based on the loading capacity of each loading location, or the number of dispatched vehicles to each loading location is determined. Based on the loading / unloading capacity of each loading / unloading place, the number of dispatched vehicles to each loading / unloading place of a plurality of transport vehicles is determined in advance. Then, in the operation management center, the transport route is selected by the selection means so that the number of dispatched vehicles is determined for each loading place or unloading place. As described above, in this transportation vehicle operation support system, each loading location of a plurality of transportation vehicles and dispatch to each loading location based on the loading capability of each loading location and the loading capability of each loading location. By determining the number of units, the transport route of each transport vehicle can be determined so as not to exceed the load capacity at the load location and the load capacity at the load location, and the waiting time at the load location and load location It is possible to suppress the decrease in the transport amount as a whole system.

In particular, when it is determined that the current location has arrived at the loading / unloading location, the computer 5c calculates the time required from the loading location to the loading / unloading location and stores the required time and the time zone information at that time in the dump truck database. sign up. If it is determined that the current location has arrived at the loading location, the computer 5c calculates the time required from the loading location to the loading location, and stores the required time and the time zone information at that time in the dump truck database. sign up.

  Each time the road condition information associated with the position information from each dump truck 2 is received, the computer 5c adds a mark of information included in the road condition information (congestion mark (congestion section) to the position on the road map image). As shown in the figure, an image on which one side lane mark, road surface damage mark, fallen object mark, road stop mark, etc.) are superimposed is generated, and the image information is output to the display 5b. Further, every time the road condition information associated with the position information from each traffic reporter 3 is received, the computer 5c superimposes a mark of information included in the road condition information on the position on the road map image. The generated image is generated, and the image information is output to the display 5b. The computer 5c registers information such as position information and time zone in the road situation database for each received road situation information. The road situation database is a database that is configured in a predetermined area of the storage device of the computer 5c and registers various information for each road situation. In particular, when the road condition information is road surface damage or a fallen object, the computer 5c associates the position information with the information and transmits it to the road maintenance station 4 by the communication device 5a. This information may be communicated by the operator through a call.

  The computer 5c generates a transportation plan (allocation plan) for all the dump trucks 2 that perform the transportation work. Transportation plans include standard transportation plans and transportation plans that take into account real-time road condition information. A standard transportation plan is generated every day before starting the transportation operation. The transportation plan considering real-time road condition information is changed whenever the road condition changes (or periodically). Therefore, if there is no change in road condition information throughout the day, a standard transportation plan is used. The transportation plan is a plan composed of transportation route information including information on loading places and unloading places for each dump truck 2. As a precondition for generating the transportation plan, loading so that the loading at the loading place will not stagnate (so that the dump truck 2 does not wait for unloading of earth and sand) so that it exceeds the loading capacity at the loading place. Secure the loading capacity of the place. In particular, in the case of a standard transportation plan, a transportation plan is generated assuming a basic state of road conditions. The basic state of the road condition is basically a state in which there is no traffic jam or traffic restriction, but if one-side lane or road closure is known in advance, such information is included in the basic state. At this time, the road conditions accumulated in the road condition database by the previous day are taken into consideration.

  When the transportation plan is specifically generated, the computer 5c is the shortest connecting the loading place and the unloading place for all loading places and all combinations of the loading places and unloading places in the plurality of loading places. The main route and the sub route longer than the main route are respectively set, and the transport distance L [m] for each route is set based on the road map information. Here, two routes are set for each combination of loading place and unloading place, but three or more routes may be set. Also, the computer 5c determines the number of dump trucks 2 to be dispatched for each loading / unloading place based on the loading / unloading capacity at each loading / unloading place so as not to exceed the loading / unloading capacity at each loading / unloading place.

  In the case of the standard transportation plan, the computer 5c, based on the basic state of the road condition, for each combination of loading place and unloading place, the standard speed V of the dump truck 2 and the transportation of each route for the main route and the sub route. Based on the distance L, a standard required time T (= transport distance L / standard speed V) for traveling between the loading place and the unloading place is calculated. The standard speed V [m / min (minutes)] is a standard speed at which the dump truck 2 can travel considering the speed limit on each route, normal traffic volume, traffic lights, and the like. In addition, when calculating the standard required time, if the required time information between the loading place and the unloading place has been accumulated in the dump truck database by the previous day, it should be calculated considering the required time information. Also good.

Then, in the computer 5c, for each combination of the loading place and the unloading place, the transporting soil amount W [m ³ / unit], the standard speed V [m / min], each route for the main route and the sub route The standard carrying capacity of the dump truck 2 is calculated using the carrying distance L [m]. The carrying capacity is the amount of soil that can be carried by one dump truck 2 in one hour, and can be calculated by 60 × speed V × carrying soil amount W / (2 × carrying distance L). The carrying capacity increases as the route takes shorter time (the amount of carrying soil increases).

  Further, in the computer 5c, the route having the highest carrying capacity among all the routes including the loading / unloading location (and the standard required time is the most) so that the number of dispatched vehicles is determined for each loading / unloading location. (Short route). Here, a standard transportation route is determined for all dump trucks 2, and a standard transportation plan is generated. The computer 5c transmits standard transport route information to each dump truck 2 by the communication device 5a. At this time, any transportation route information may be transmitted to any dump truck 2. For example, based on the current position of the dump truck 2, transportation route information including a loading place where the current position is close is transmitted.

  When the real-time road condition information has changed from the normal time, the computer 5c sets a time T ′ that increases with respect to the required time T at the standard time in accordance with the changing road condition information. For example, in the case of traffic jam information, T ′ is increased by 1.0 min or more, and the time is increased as the length of the traffic jam increases (for example, T ′ is increased by 1.0 min every 100 m). T ′ = 2.0 min per location, T ′ = 0.5 min per location for road surface damage, T ′ = 0.5 min per location for fallen objects, and T ′ = 10000 min. In addition, based on the required time information stored in the dump truck database and the road condition information stored in the road condition database, the increase time T ′ is changed in consideration of the increase required time during actual driving. You may make it do.

Then, the computer 5c selects a route including the position from the main route and the sub route for all combinations of the loading place and the unloading place based on the position information of the changing road condition, The increase time T ′ is added to the standard required time T of each selected route, and the added value is set as a required time ΣT. At this time, for the route with the standard required time T, the post-addition required time ΣT = standard required time T. Then, the computer 5c uses the transported soil amount W [m ³ / unit] of the dump truck 2 and the post-addition required time ΣT [min] for the main route and the sub route for each combination of the loading place and the unloading place. The carrying capacity (= 60 × W / (2 × ΣT)) of the dump truck 2 is calculated. Further, the computer 5c selects the route having the highest carrying capacity from all the routes including the loading / unloading location so that the number of dispatched vehicles is determined for each loading / unloading location. Then, the computer 5c transmits the changed transport route information to each dump truck 2 by the communication device 5a. Since the average speed V ′ of the route can be calculated by the transport distance L / the required time ΣT after the addition using the required time ΣT after the addition, the transport capacity (= 60 × V ′ × W is calculated using the average speed V ′. / (2 × L)) can also be calculated.

  In particular, when the route with the highest carrying capacity is selected, if the dump trucks 2 for the number of vehicles dispatched perform the loading operation at the loading place included in the selected route, the computer 5c will load When selecting a route from all routes including the loading / unloading location so that the number of dispatched vehicles is determined for each wholesale location, do not exceed the loading capacity (if there are multiple loading locations) Sequentially select the route with the highest carrying capacity and the second highest route or the third, fourth, etc. route (as assigned to the location). The other route is a route including a loading place different from the loading place included in the highest route. The route with the highest carrying capacity and the second highest route or the third, fourth, etc. high route are combined so that the number of dispatched vehicles is determined. At this time, dump trucks 2 corresponding to the number of vehicles dispatched are allocated to the two routes so that the amount of transported soil is as high as possible. Then, the computer 5c transmits the changed transport route information to each dump truck 2 by the communication device 5a.

  When the transportation work for one day is completed, the computer 5c uses the movement data of the dump truck 2 accumulated in the dump truck database, the data of the required time, etc. to determine the actual required time, transportation cycle, transportation capacity, etc. for the transportation plan. analyse. Then, in consideration of the analysis result, the computer 5c generates a transportation plan for the next and subsequent times, sets an increase time T ′, and the like.

  Next, with reference to FIG.1 and FIG.2, the flow of operation | movement in the dump operation assistance system 1 is demonstrated. Here, the flow of operation for generating a transportation plan (transportation route information of each dump truck 2) will be described.

  In the computer 5c of the operation management center 5, each information for each dump truck 2 is registered in the dump truck database by the operator, each information for each major intersection is registered in the major intersection database, and each information for each loading place is loaded. It is registered in the location database and each piece of information for each loading location is registered in the loading location database.

  Prior to starting the transport operation, the traffic reporter 3 is placed at the main intersection in charge. Further, the computer 5c of the operation management center 5 sets the main route and the sub route for each combination of the loading place and the unloading place, and sets the transport distance L [m] for each route. Further, the computer 5c determines the number of dump trucks 2 to be dispatched for each loading / unloading place based on the loading / unloading capacity of each loading / unloading place. In the computer 5c, for each combination of the loading place and the unloading place, the standard required time T of the route is determined for the main route and the sub route based on the standard speed V of the dump truck 2 and the transport distance L of each route. calculate. Further, in the computer 5c, for each combination of the loading place and the unloading place, the standard of the dump truck 2 is used for the main route and the sub route by using the transport amount W of the dump truck 2, the standard speed V, and the transport distance L of each route. Calculate the carrying capacity. The computer 5c selects the route having the highest carrying capacity from all the routes including the loading / unloading location so that the determined number of dispatched vehicles is obtained for each loading / unloading location. Are respectively transmitted by the communication device 5a.

  Each dump truck 2 receives standard transportation route information by the communication function of the mobile terminal 2a. The mobile terminal 2a displays standard transportation route information on the display. When the driver sees the displayed transportation route information, the driver operates the dump truck 2 to perform transportation on the standard transportation route. Here, each dump truck 2 starts transportation according to a standard transportation route.

  In each dump truck 2, when the driver finds a change in road conditions different from the normal time during transportation, the information providing application of the mobile terminal 2a is activated. Alternatively, an information providing application is activated in advance. In the mobile terminal 2a, a button for inputting a road map around the current position and road condition information is displayed on the display. The driver presses the button corresponding to the found road condition. In the mobile terminal 2a, information in which the current position information is associated with the road condition information of the pressed button is transmitted to the operation management center 5 by the communication function. Further, when the traffic reporter 3 finds a change in road conditions different from the normal time, the traffic reporter 3 transmits (or calls) the road condition information to the operation management center 5 by the mobile phone 3a.

  When the road condition information is transmitted from the dump truck 2, the communication device 5a of the operation management center 5 receives the information and outputs the information to the computer 5c. Further, when the road information is transmitted from the traffic reporter 3, the communication device 5 a receives the information and outputs the information to the computer 5 c. When the operator of the operation management center 5 receives information from the traffic reporter 3 by telephone, the operator inputs the information to the computer 5c.

  When new road condition information is input, the computer 5c determines whether or not the current road condition has changed due to the new road condition information. When the road condition has changed, the computer 5c sets the increase time T 'according to the information on the changing road condition. Then, the computer 5c selects a route including the position from the main route and the sub route for all combinations of the loading place and the unloading place based on the position information of the changing road condition information. Then, the increase time T ′ is added to the standard required time T of each selected route, and the added value is set as a post-added required time ΣT. Then, the computer 5c calculates the carrying capacity of the dump truck 2 for each combination of the loading place and the unloading place, using the carrying soil amount W of the dump truck 2 and the required time ΣT after addition for the main route and the sub route. Further, the computer 5c selects the route having the highest carrying capacity from all the routes including the loading / unloading location so that the number of dispatched vehicles is determined for each loading / unloading location. In this case, if the loading capacity at the loading place is exceeded, the computer 5c has the route with the highest carrying capacity so as not to exceed the loading capacity so that the number of dispatched vehicles is determined for each loading place. The second highest route or the third highest route, the fourth highest route, etc. are sequentially selected and allocated to the two routes so that the amount of transported soil is as much as possible. Then, the computer 5c transmits the changed transport route information to each dump truck 2 by the communication device 5a.

  Each dump truck 2 receives the changed transportation route information by the communication function of the mobile terminal 2a. In the mobile terminal 2a, the changed transport route information is displayed on the display. When the driver sees the displayed transport route information, the driver operates the dump truck 2 and transports the transport route after the change from the next transport operation. Here, in each dump truck 2, it changes to a conveyance route and continues conveyance.

  And said operation | movement is repeated until the conveyance work of one day is complete | finished. In addition, although the change of the transportation plan (transport route information of each dump truck) is performed when the road condition is changed, it may be performed periodically (for example, every hour or every two hours).

  With reference to FIGS. 3-6, the Example of the production | generation of the conveyance plan at the time of applying the dump operation assistance system 1 (especially the process by the computer 5c of the operation management center 5) is demonstrated.

The loading capability XA at the loading location A is 120 m ³ / h, the loading capability XB at the loading location B is 100 m ³ / h, and the loading capability XC at the loading location C is 80 m ³ / h. In addition, the unloading capacity Ya at the unloading place a is 80 m ³ / h, the unloading capacity Yb at the unloading place b is 80 m ³ / h, and the unloading capacity Yc at the unloading place c is 80 m ³ / h. . In this way, the loading capacity exceeding the loading capacity at the loading place is secured, so that the loading at the loading place is not stagnated. Further, the route between the loading place and the unloading place has a main route (shortest route) and a sub route. Note that each route shown in FIG. 3 is a schematic representation of the route of loading and unloading locations. Actually, some of the routes overlap or cross each other. Is included in the other route. Therefore, the road condition information for each route may include information that can be used for other routes.

In this embodiment, the number of dump trucks is 30 and the amount of transported soil W of each dump truck is 5.0 m ³ / unit. Since the number of dump trucks is 30 and the unloading capacity of the unloading places a, b, c is 80 m ³ / h, the number of dispatched cars at each unloading place a, b, c is determined to be 10 units. .

  A standard transportation plan will be described with reference to the example of FIG. The standard speed V of each dump truck is set to 250 m / min (minutes) = 15 km / h (hours). Therefore, as shown by the standard required speed T in FIG. 4, when the dump truck travels at the standard speed V, the standard required time T (= transport distance L / standard speed V) on one way of the main route Aa1 is 20.0 min.

Here, 10 dump trucks on the main route Aa1 are dispatched to the loading place A. Since the main route Aa1 has a standard carrying capacity of 7.50 m ³ / h, the total value of the loading amount per hour at the loading place A is 75.0 m ³ / h. This does not exceed the loading capacity 120m ³ / h at loading location A. Also, 10 dump trucks on the main route Bb1 are dispatched to the loading place B. Since the main route Bb1 has a standard carrying capacity of 7.50 m ³ / h, the total value of the loading amount per hour at the loading place B is 75.0 m ³ / h. This does not exceed the loading capacity of loading place B of 100 m ³ / h. Also, 10 dump trucks on the main route Cc1 are dispatched to the loading place C. Since the main route Ca1 has a standard carrying capacity of 7.50 m ³ / h, the total value of the loading amount per hour at the loading place C is 75.0 m ³ / h. This does not exceed the loading capacity 80m ³ / h of loading place C.

Also, 10 dump trucks on the main route Aa1 are dispatched to the unloading place a. Since the main route Aa1 has a standard carrying capacity of 7.50 m ³ / h, the total value of the unloading amount per hour at the unloading place a is 75.0 m ³ / h. This does not exceed the unloading capacity 80 m ³ / h of the unloading place a. Also, 10 dump trucks on the main route Bb1 are dispatched to the unloading place b.

Therefore, the standard transportation plan is that 10 dump trucks are allocated to the main route Aa1 as the loading place A and the loading place a, and 10 dump trucks are set as the main route Bb1 as the loading place B and the loading place b. And 10 dump trucks are planned to be dispatched to the main route Cc1 as the loading place C and the unloading place c. In this dispatching plan, as shown in the total carrying soil amount in FIG. 4, the total carrying soil amount per hour is 75.0 + 75.0 + 75.0 = 225.0 m ³ / h. This is the largest total carrying volume of all routes. Further, the work amount in this case (= transport distance of the shortest route × total transported soil amount) = 5.000 × 225.0 = 1125 m ³ · km.

In this case, the main route Aa1 is not the highest carrying ability (not the shortest required post-addition time ΣT) in terms of carrying ability in the route where the unloading place is a. Similarly, the main route Bb1 is not the highest transport capability among routes where the loading / unloading location is b. The main route Cc1 is not the highest carrying capacity among routes where the loading / unloading place is c. As a result, as shown in FIG. 5 (a), the total loading amount per hour at loading places A, B and C is 60.0 m ³ / h, respectively, and the total amount of soil transported per hour Is 60.0 + 60.0 + 60.0 = 180.0 m ³ / h. This is not the maximum total carrying capacity of all routes.

Therefore, as shown in FIG. 5B, when comparing the carrying capacity of the route where the loading place is a, the carrying capacity of the sub route Aa2 is 6.82 m ³ / h, which is the highest (the required time is the shortest). Therefore, the sub route Aa2 is selected for 10 dump trucks to be dispatched to the unloading place a. In addition, when comparing the carrying capacity of the route where the unloading place is b, the carrying capacity of the sub route Bb2 is the highest, 6.82 m ³ / h. Route Bb2 is selected. In addition, when comparing the carrying capacity of the route where the loading / unloading place is c, the carrying capacity of the sub route Cc2 is the highest, 6.82 m ³ / h, so the 10 dump trucks dispatched to the loading place c are Route Cc2 is selected.

Here, 10 dump trucks on the sub route Aa2 are dispatched to the loading place A. Since the sub route Aa2 has a carrying capacity of 6.82 m ³ / h, the total value of the loading amount per hour at the loading place A is 68.2 m ³ / h. This does not exceed the loading capacity 120m ³ / h at loading location A. Also, 10 dump trucks on the sub route Bb2 are dispatched to the loading place B. Since the sub route Bb2 has a carrying capacity of 6.82 m ³ / h, the total value of the loading amount per hour at the loading place B is 68.2 m ³ / h. This does not exceed the loading capacity of loading place B of 100 m ³ / h. Also, 10 dump trucks on the sub route Cc2 are dispatched to the loading place C. Since this sub route Ca2 has a carrying capacity of 6.82 m ³ / h, the total value of the loading amount per hour at the loading place C is 68.2 m ³ / h. This does not exceed the loading capacity 80m ³ / h of loading place C.

Also, 10 dump trucks on the sub route Aa2 are dispatched to the unloading place a. Since this sub route Aa2 has a carrying capacity of 6.82 m ³ / h, the total value of the unloading amount per hour at the unloading place a is 68.2 m ³ / h. This does not exceed the unloading capacity 80 m ³ / h of the unloading place a. Also, 10 dump trucks on the sub route Bb2 are dispatched to the unloading place b. Since the sub route Bb2 has a carrying capacity of 6.82 m ³ / h, the total value of the unloading amount per hour at the unloading place b is 68.2 m ³ / h. This does not exceed the unloading capacity 80 m ³ / h of the unloading place b. Also, 10 dump trucks on the sub route Cc2 are dispatched to the loading / unloading place c. Since the sub route Cc2 has a carrying capacity of 6.82 m ³ / h, the total value of the unloading amount per hour at the unloading place c is 68.2 m ³ / h. This does not exceed the unloading capacity of the unloading place c of 80 m ³ / h.

It is planned that 10 dump trucks will be dispatched to the sub route Cc2 which is set as the loading place C and the unloading place c. In this dispatching plan, as shown in the total carrying soil amount in FIG. 5B, the total carrying soil amount per hour is 68.2 + 68.2 + 68.2 = 204.6 m ³ / h. This is the largest total carrying volume of all routes. In this case, the workload is 5.000 × 204.6 = 1023 m ³ · km.

The speed V ′ of the route Cc1 is calculated as 192.3 m / min, and the speed V ′ of the sub route Cc2 is calculated as 196.4 m / min. The transportation capacity of each route may be calculated using each speed V ′.

FIG. 6A shows a case where 10 dump trucks are allocated to the main route Aa1 in the standard transportation plan, 10 dump trucks are allocated to the main route Bb1, and 10 dump trucks are allocated to the main route Cc1. Is shown. In this case, the main route Aa1 is not the highest carrying capacity (not the shortest required time) when comparing carrying ability in the route where the loading / unloading place is a. Similarly, the main route Bb1 is not the highest transport capability among routes where the loading / unloading location is b. The main route Cc1 is not the highest carrying capacity among routes where the loading / unloading place is c. As a result, as shown in FIG. 6 (a), the total amount of loading per hour at loading locations A, B, and C is 57.7 m ³ / h, respectively, and the total amount of soil transported per hour Is 57.7 + 57.7 + 57.7 = 173.1 m ³ / h. This is not the maximum total carrying capacity of all routes.

Therefore, as shown in FIG. 6 (b), when comparing the carrying capacity of the route where the loading place is a, the carrying capacity of 6.82 m ³ / h of the main route Ba1 is the highest (the required time is the shortest). Therefore, the main route Ba1 is selected for 10 dump trucks to be dispatched to the unloading place a. Further, when comparing the carrying capacity of the route where the unloading place is b, the carrying capacity of 6.82 m ³ / h of the main route Ab1 and the main route Cb1 is the highest. For the cars, the main route Ab1 for five cars and the main route Cb1 for the other five cars are selected. In addition, when comparing the carrying capacity of the route where the loading / unloading place is c, the carrying capacity of the main route Bc1 is 6.82 m ³ / h, which is the highest for 10 dump trucks to be dispatched to the loading / unloading place c. The route Bc1 is selected.

Here, five dump trucks on the main route Ab1 are dispatched to the loading place A. Since the main route Ab1 is carrying capacity is at 6.82m ³ / h, the total value of the loading amount per 1 hour of loading location A is 34.1m ³ / h. This does not exceed the loading capacity 120m ³ / h at loading location A. In addition, five dump trucks on the main route Cb1 are dispatched to the loading place C. Since the main route Cb1 is carrying capacity is at 6.82m ³ / h, the total value of the loading amount per 1 hour of loading location C is 34.1m ³ / h. This does not exceed the loading capacity 80m ³ / h of loading place C. However, 10 dump trucks on the main route Ba1 and 10 dump trucks on the main route Bc1 are dispatched to the loading place B. Since the main route Ba1, Bc1 the carrying capacity is at 6.82m ³ / h, the total value of the loading amount per 1 hour of loading location B is 136.4m ³ / h. This exceeds the loading capacity of loading place B of 100 m ³ / h. Therefore, when this transportation plan is used, the loading operation at the loading place B is stagnated, so this transportation plan cannot be used. Therefore, it is necessary to allocate 10 units of the main route Ba1 selected for the loading / unloading location a and 10 units of the main route Bc1 selected for the loading / unloading location c so as not to concentrate on the loading location B.

Therefore, as shown in FIG. 6C, when comparing the carrying capacity of the route where the loading place is a, the highest carrying ability among the routes where the loading place is not B is the carrying ability of the main route Aa1. Since it is 5.77 m ³ / h, three cars are allocated to the main route Aa1 where the loading place is A. Therefore, the main route Ba1 (for 7 vehicles) and the main route Aa1 (for 3 vehicles) are selected for 10 dump trucks that are dispatched to the unloading place a. Similarly, when the carrying capacity of the route where the loading / unloading place is c is compared, the highest carrying capacity among the routes where the loading place is not B is 5.77 m ³ / h of the carrying capacity of the main route Cc1. Allocating three cars to the main route Cc1 where the loading place is C. Accordingly, the main route Bc1 (for 7 vehicles) and the main route Cc1 (for 3 vehicles) are selected for 10 dump trucks that are dispatched to the unloading place c. The number of vehicles on the main route Ba1 and the main route Bc1 is set to seven each in order not to exceed the loading capacity of the loading place B of 100m ³ / h in order to increase the amount of transported soil as much as possible. This is because the number of dispatched vehicles is as follows.

Here, three dump trucks on the main route Aa1 and five dump cars on the main route Ab1 are dispatched to the loading place A. Since the main route Aa1 has a carrying capacity of 5.77 m ³ / h and the main route Ab1 has a carrying capacity of 6.82 m ³ / h, the total value of the loading amount per hour at the loading place A is 51.4 m ³ / h. This does not exceed the loading capacity 120m ³ / h at loading location A. In addition, 7 dump trucks on the main route Bb1 and 7 dump cars on the main route Bc1 are dispatched to the loading place B. Since the main route Bb1, Bc1 the carrying capacity is at 6.82m ³ / h, the total value of the loading amount per 1 hour of loading location B is 95.5m ³ / h. This does not exceed the loading capacity of loading place B of 100 m ³ / h. In addition, it is five dump trucks on the main route Cb1 and three dump cars on the main route Cc1 that are dispatched to the loading place C. Since the main route Cb1 has a carrying capacity of 6.82 m ³ / h and the main route Cc1 has a carrying capacity of 5.77 m ³ / h, the total value of the loading amount per hour at the loading place C is 51.4 m ³ / h. This does not exceed the loading capacity 80m ³ / h of loading place C.

In addition, three dump trucks on the main route Aa1 and seven dump trucks on the main route Ba1 are dispatched to the unloading place a. Since the main route Aa1 has a carrying capacity of 5.77 m ³ / h and the main route Ba1 has a carrying capacity of 6.82 m ³ / h, the total value of the unloading amount per hour at the unloading place a is 65.0 m ³ / h. This does not exceed the unloading capacity 80 m ³ / h of the unloading place a. Further, five dump trucks on the main route Ab1 and five dump cars on the main route Cb1 are dispatched to the loading / unloading place b. Since the main routes Ab1 and Cb1 have a carrying capacity of 6.82 m ³ / h, the total value of the unloading amount per hour at the unloading place b is 68.2 m ³ / h. This does not exceed the unloading capacity 80 m ³ / h of the unloading place b. In addition, it is seven dump trucks of the main route Bc1 and three dump cars of the main route Cc1 that are dispatched to the loading / unloading place c. Since the main route Bc1 has a carrying capacity of 6.82 m ³ / h and the main route Cc1 has a carrying capacity of 5.77 m ³ / h, the total value of the unloading amount per hour at the loading place c is 65.0 m ³ / h. This does not exceed the unloading capacity of the unloading place c of 80 m ³ / h.

Therefore, the transportation plan after this change is that three dump trucks are dispatched to the main route Aa1 which is the loading place A and the unloading place a, and five cars are on the main route Ab1 which is the loading place A and the unloading place b. The dump trucks are dispatched, seven dump trucks are dispatched to the main route Ba1 as the loading place B and the unloading place a, and seven dump cars are dispatched to the main route Bc1 as the loading place B and the unloading place c. Then, five dump trucks are allocated to the main route Cb1 as the loading place C and the unloading place b, and three dump trucks are allocated to the main route Cc1 as the loading place C and the loading place c. . In this dispatching plan, as shown in the total carrying soil amount in FIG. 6C, the total carrying soil amount per hour is 51.4 + 95.5 + 51.4 = 198.3 m ³ / h. This is smaller than the total transported soil amount 204.5 m ³ / h shown in FIG. 6B, but is the maximum total transported soil amount in consideration of the loading capacity of the loading place. In this case, the work amount = 5.000 × 198.3 = 991.5 m ³ · km.

  According to the dump operation support system 1, real-time road condition information is collected from the dump truck 2, etc., and the main route and the sub route are determined for each combination of loading place and unloading place based on the real-time road condition information. By calculating the required time and selecting a route with a short required time from each route, it is possible to provide the optimum transport route information to the plurality of dump trucks 2. Thus, since a short transportation route is selected for each dump truck 2, the amount of transport soil per unit time in each dump truck 2 increases, and the amount of transport soil that can be transported as a whole system becomes very large. (In some cases, it will be the maximum amount of transported soil). Further, since real-time road condition information can be collected from each dump truck 2 or the like, it can be changed to a transportation route whose required time is shortened in real time according to a change in the road condition information.

  In particular, according to the dump operation support system 1, the transport capacity for the main route and the sub route is calculated for each combination of the loading place and the unloading place using the time required in consideration of real-time road condition information. By selecting a route having a high carrying capacity from the routes, it is possible to provide optimum carrying route information to the plurality of dump trucks 2. In addition, according to the dump operation support system 1, by changing the transportation route based on the loading capacity of each loading place, the transportation route can be determined so as not to exceed the loading capacity of all loading places, The waiting time at the loading place can be suppressed, and the decrease in the amount of transported soil can be suppressed as a whole system. Further, according to the dump operation support system 1, by determining the number of dispatched vehicles to each loading place for a plurality of dump trucks 2 based on the loading / unloading capacity of each loading place, all loading places are loaded. The transportation route can be determined so as not to exceed the unloading capacity, the waiting time at the loading place can be suppressed, and the decrease in the amount of transportation soil can be suppressed as a whole system.

In addition, the dump car may incorporate the above-described function performed by the mobile terminal in an in-vehicle navigation system or the like instead of the mobile terminal.

  In the present embodiment, a plurality of loading places and a plurality of loading places are used. However, the loading place may be one place, or the loading place may be one place.

  In the present embodiment, the road condition information input by the driver of each dump truck is acquired. However, the road condition information may be acquired by other means, for example, detected by an image sensor mounted on the dump truck. The road condition information may be acquired from the fallen object, road surface damage, one-sided traffic condition, traffic jam information estimated from vehicle speed change information detected by the vehicle speed sensor, and the like.

  In this embodiment, the transportation route information is the same route information from the loading location to the loading location and the route from the loading location to the loading location, but from the loading location to the loading location. The forward route and the return route from the loading / unloading location to the loading location may be different route information. Since road conditions such as traffic jams may differ depending on directions even on the same road, the required time for transportation may be shortened (the transportation capacity can be increased) by changing the route between the forward path and the return path.

  In this embodiment, the required time of the route is calculated, the transport capacity is calculated from the required time, and the transport route is selected based on the transport capacity. However, the required time is calculated without calculating the transport capacity. The transport route may be selected based on

  In this embodiment, the number of dispatched vehicles for each loading / unloading place is determined in advance according to the loading / unloading capacity of each loading / unloading place, and the transportation route is selected so that the number of dispatched vehicles for each loading / unloading place is the same. However, after determining the number of vehicles to be dispatched for each loading location according to the loading capacity of each loading location, select the transportation route so that the number of dispatched vehicles for each loading location is the same. It is also possible to determine the number of vehicles to be dispatched at each loading place according to the loading capacity at each loading place and to determine the number of vehicles to be dispatched at each loading place according to the loading capacity at each loading place. You may make it select a conveyance route so that it may become the number of vehicles dispatched for every loading place, and the number of dispatched vehicles for every unloading place. Or you may be made to select a conveyance route, without determining the number of dispatches for every such loading place and the number of dispatching for every unloading place.

  Also, in this embodiment, when the route with the highest carrying capacity is selected, if the loading capacity at the loading location is exceeded, a route with a lower carrying capacity is also selected so that the loading capacity is not exceeded. However, if the route with the highest carrying capacity is selected and the unloading capacity of the unloading place is exceeded, a route with a lower carrying capacity is also selected and configured so as not to exceed the unloading capacity. Also good.

  In the present embodiment, the transport route of each transport vehicle is selected so that the total transport soil amount increases, and the transport route of each transport vehicle is selected so that the total transport soil amount becomes maximum. In addition, the transport route of each transport vehicle may be selected so that the work amount (= transport distance of the shortest route × total transport soil amount) increases, and further, the transport route of each transport vehicle so as to maximize the work amount. May be selected. If you want to advance the total amount of transported soil, you can select a transport route so that the total amount of transported soil increases, and if you want to progress the cumulative amount of work, select the transport route so that the amount of work increases. That's fine.
