Electric car charging dispatching method and system based on Internet of Things

Abstract

The invention discloses an electric car charging dispatching method and system based on the Internet of Things. The dispatching system comprises a sensing layer, a network layer and an application layer. The sensing layer comprises an electric car sensing component for obtaining electric car preference data information and a charging station sensing component for obtaining charging station preference data information. The network layer is a data center server of the Internet of Things and is used for data transmission between the sensing layer and the application layer. The application layer is used for computing dispatching results according to data information collected by the sensing layer and sending the dispatching results to the network layer. The whole system is established based on three models of the Internet of Things, the interconnection feature of the Internet is fully used, a dispatching result generated by a used Gale-Shapley algorithm has the stability on Pareto efficiency, so that best matching of an electric car and a charging station is achieved, electric car dispatching is carried out efficiently in order, therefore, the queuing waiting time of electric cars is shortened, and charging station resources are used reasonably.

Description

technical field [0001] The present invention relates to the application field of the Internet of Things, and specifically refers to a charging scheduling method and system for electric vehicles based on the Internet of Things. Background technique [0002] With the development of society, oil and gas resources are becoming more and more tense, and the problem of environmental pollution is becoming more and more prominent. People pay more and more attention to electric vehicles. The charging station provides energy supply for the operation of electric vehicles, and can provide fast charging services for various types of electric vehicles at the same time. Considering the limited number of charging stations in a certain area and the long charging time of electric vehicles, the scheduling of electric vehicle charging is particularly important. [0003] At present, the Internet of Things technology is on the rise and has a broad space for development. The Internet of Things, w...

Problems solved by technology

[0004] Electric vehicle charging scheduling is a resource scheduling problem. At present, there are generally two solutions to the problem of electric vehicle charging scheduling. One is to schedule according to the simple first-come-first-charge principle. The station problem is completely randomly selected by the car owner, and there is no scientific scheduling plan

The second is to use modern heuristic algorithms such as genetic algorithm and ant colony algorithm to solve the scheduling problem. The defects of these algorithms are mainly manifested in two aspects. Stable matching results; the second is that although the objective functions set by these algorithms for the system model can produce one or more approximate solutions under constraints, it is difficult for these approximate solutions to make the resource allocation results Pareto efficient stability, that is, the matching results produced by these algorithms are difficult to reach the optimal state of resource allocation
