The application firstly discloses a multipoint transportation scheduling method, and an implementation terminal of the multipoint transportation scheduling method can be a server or a cloud server, and also can be terminal equipment with data operation, processing and communication functions, such as a notebook computer, a tablet computer, a smart phone and the like, and is implemented by depending on an internet of things scheduling platform.
As shown in fig. 1, the specific steps are as follows:
step S101: and receiving a transportation order, wherein the transportation order comprises geographical position information of an arrival place of the goods transportation, quantity information of the arrival place, geographical position information of a departure place, transportation timeliness information and information of the transported subject matter. For example, a transportation requirement user registers on a dispatching platform and inputs a transportation requirement to order to the dispatching platform, wherein the transportation requirement comprises: the information of the geographical position of the arrival place, the number of the arrival places, the geographical position of the departure place, the transportation aging information and the information of the transported subject matter.
Step S102: providing a plurality of candidate transportation plans according to a carrier vehicle, transportation time, a geographical range related to transportation, regional traffic road conditions, transportation target object conditions and a scheduling principle; the scheduling principle is periodically optimized according to national road transportation regulations, local geographical positions and traffic road conditions; judging the candidate transportation plans, and obtaining an optimal transportation plan from the candidate transportation plans by combining a judgment conclusion; the candidate transportation plan content comprises main line transportation vehicle information, branch line transportation vehicle information, an integral transportation route, each transportation time node and a running route on the transportation route, vehicle departure time and estimated completion time; the main line transport vehicle refers to a transport vehicle which starts from a transport order starting place; the branch transport vehicles refer to transport vehicles that do not originate from the origin of the transport order. For example: after receiving the transportation order, the dispatching platform firstly plans a plurality of reasonable transportation routes, the number of main line transportation vehicles and the number of branch line transportation vehicles according to the departure place and the arrival place of the transportation time, and then screens the provided transportation routes by combining the transportation regulations related to transportation of the transportation routes, the number of transportation targets, the number of supportable vehicles and the dispatching principle dimension, and forms a plurality of candidate transportation plans.
Step S103: and performing comment judgment on the plurality of candidate transportation plans, and selecting a preferred transportation plan from the plurality of candidate transportation plans by combining the comment judgment result. The dispatching platform can judge the candidate transportation plan from two aspects of time efficiency and energy consumption. When the dispatching platform judges, the dispatching platform can predict the transportation time of each candidate transportation plan and give out the time effectiveness judgment of a plurality of candidate transportation plans; judging the fuel use condition of each candidate transportation plan by combining the vehicle types and the fuel consumption conditions of the main line transportation vehicle and the branch line transportation vehicle which are carried in each candidate transportation plan, giving out the fuel use judgment of a plurality of candidate transportation plans, judging the carrying route occupation ratio of the new energy vehicle in each candidate transportation plan, giving out the environmental protection judgment of a plurality of candidate transportation plans, synthesizing the fuel use judgment and the environmental protection judgment results to obtain the energy consumption judgment, and finally selecting the preferred transportation plan by combining the aging judgment and the energy consumption judgment.
Optionally, in some embodiments, since the candidate transportation plan can fulfill the transportation order requirement by arranging only the main transportation vehicle, and the branch transportation vehicles are not required to participate in the transportation, the selected preferred transportation plan may have a situation where only the main transportation vehicle has no branch transportation vehicle.
Step S104: sending an optimized transportation plan to a main line transportation vehicle and a branch line transportation vehicle which bear the transportation plan; after receiving the optimized transportation plan, the main line transportation vehicle and the branch line transportation vehicle update and send the basic information of the current vehicle, and simultaneously keep monitoring on the transportation vehicles in the whole transportation process.
The dispatch platform, upon selecting the preferred transportation plan, sends the preferred transportation plan information to the planned carrier vehicles, the preferred transportation plan information including: main line transportation vehicle information, branch line transportation vehicle information, each transportation vehicle number, departure place information of each transportation vehicle, number and information of arrival places, predicted departure and arrival time and transportation routes.
Optionally, in some embodiments, there may be a case where step S103 and step S104 are performed cooperatively. The dispatching platform sends an optimal transportation plan to the main line transportation vehicle bearing the transportation plan and keeps monitoring the transportation process of the optimal transportation plan, and then finally determines the branch line transportation vehicle according to the transportation progress condition of the main line transportation vehicle and sends the optimal transportation plan. For example: because the main line transport vehicle in the optimized transport plan can not send the goods to the arrival place according to the original plan time, the original branch line transport vehicle in the plan can not complete the carrying work due to weather or forbidden time, the scheduling platform can determine the branch line transport vehicle which is carried finally according to the monitoring condition of the main line transport vehicle and inform the branch line transport vehicle which is carried; of course, if the finally determined information of the branch transportation vehicles is changed compared with the information in the original preferred transportation plan, the dispatching platform sends the changed information to the main transportation vehicle.
