step S202, constructing a undirected network graph with the first charging piles as vertexes based on historical data of the plurality of first charging piles.
Optionally, the first charging pile may be a charging pile in a predetermined area, for example, all charging piles in a city; the historical data may be usage data of the first charging post over a period of time, such as usage data over a week or a month; the historical data can include data such as the time length of each operation of the first charging pile, the electricity price, the charging rate, the number of the vehicle to be charged, the payment account number and the like. When the undirected network graph is constructed, a mode that each first charging pile is used as a vertex and an edge between two charging piles is created according to a certain rule can be adopted, and the rule for creating the edge can be that more important one charging pile is, and more edges are created for the charging pile when the influence on other charging piles in operation, maintenance and overhaul work is larger.
And step S204, screening out at least one second charging pile from the plurality of first charging piles based on the undirected network diagram. In this step, the second of screening out fills electric pile can regard as the comparatively important batch of electric pile that fills in the predetermined area, can regard it as the key electric pile that fills, and this batch of electric pile that fills can play demonstration effect or marker post effect in operation and maintenance work.
And S206, determining the operation state of the third charging pile by comparing the second charging pile with the third charging pile, and maintaining the third charging pile according to the operation state, wherein the third charging pile is different from the second charging pile in the first charging pile.
In this step, the third charging pile may be any one of the first charging piles other than the second charging pile, and according to this embodiment, the second charging pile (i.e., the screened key charging pile) may be used as a standard to determine the operating states of the other charging piles in the predetermined area, and determine whether the other charging piles need to be maintained to overhaul the charging pile that needs to be maintained.
Through the steps, a multidirectional network diagram mode with the first charging piles as vertexes is established by adopting historical data based on the first charging piles, at least one second charging pile is screened out from the first charging piles based on the multidirectional network diagram, the running state of the third charging pile is determined by comparing the second charging pile with the third charging pile, the third charging pile is maintained according to the running state, the aim of improving the charging pile maintenance efficiency by improving the pertinence of the charging pile maintenance work in the region is achieved, the technical effects of reducing the maintenance work consumption caused by too many charging piles in the region and improving the maintenance efficiency are achieved, and the technical problems that the maintenance work consumption is large and the efficiency is low due to too many charging piles in the region are solved.
As an alternative embodiment, based on the historical data of the plurality of first charging piles, a undirected network graph with the first charging piles as vertexes is constructed, and the following method can be adopted: determining a first vehicle using the first charging post based on historical data of the plurality of first charging posts; under the condition that a second vehicle included in the first vehicle uses at least two first charging piles, connecting the first charging piles used by the second vehicle to obtain a side corresponding to the second vehicle, wherein the end point of the side is the first charging pile used by the second vehicle; based on the edges, a undirected network graph is constructed.
Optionally, the charging piles are used as network vertices, if one user or one vehicle charges electricity on two different charging piles once, a connection line is established on the two vertices to obtain one edge of the undirected network graph, and after the historical data record of the preset time period is analyzed, a complex undirected network graph can be formed according to the charging record data of all the first vehicles. The method for constructing the phase-free network graph can realize that all vertexes are covered by using the minimum vertexes through transmission.
As an optional embodiment, based on the undirected network graph, screening out at least one second charging pile from the plurality of first charging piles, includes: calculating the value of each first charging pile in the undirected network diagram; based on the value of first electric pile of filling, sieve out at least one second electric pile of filling from first electric pile.
It should be noted that the value represents the number of edges connected to a vertex in the undirected network graph, and since the undirected network graph is used in this embodiment, the in-degree and out-degree of the vertex are not distinguished. For the charging pile, the higher the value of the charging pile is, the more vehicles can be selected to be charged by the charging pile on the basis of selecting other charging piles, and the charging pile is more popular with users. In addition, the charging pile with the high value can also become a standard of more charging piles in the data analysis process, for example, if operation and maintenance personnel determine that the charging pile with the high value is good in running state and each parameter is normal, the charging pile can be selected as a key pile, vehicles which are charged in the key pile and other charging piles are selected through data mining, charging data of the vehicles on the two types of charging piles are analyzed, and whether errors or equipment faults exist in other charging piles compared with the key pile or not is judged through comparison, so that data detection of other charging piles adjacent to the key pile in the undirected network diagram of the predetermined area is realized. It should be noted that charging piles adjacent to the key piles in the undirected network diagram are not necessarily adjacent to the key piles in the physical space.
As an optional embodiment, based on the value of the first charging pile, at least one second charging pile is screened out from the first charging pile, which may be as follows: determining a first-order central index of any one charging pile in the first charging piles, wherein the first-order central index comprises a value of any one charging pile; determining a second-order central index of any one charging pile, wherein the second-order central index comprises the number of fourth charging piles, the fourth charging piles are charging piles connected with fifth charging piles, the fifth charging piles are charging piles connected with any one charging pile, and the fourth charging piles are different from the fifth charging piles; determining a vertex center index of any one charging pile in the first charging piles according to the first-order center index and the second-order center index; and sequencing the first charging piles based on the vertex center indexes, and determining the first charging piles in the front sequencing as second charging piles.
Optionally, in this optional embodiment, the first-order central index and the second-order central index of each of the plurality of first charging piles may be sequentially calculated, and then the vertex central index of each charging pile in the undirected network graph is calculated. Through summit center index, can judge the influence radiation scope that each fills in first electric pile, fill electric pile determination to influence the bigger second of radiation scope through the sequencing and fill electric pile, select the key stake of predetermined area promptly.
As an optional embodiment, the method for screening out at least one second charging pile from the plurality of first charging piles further includes: determining the number of times of use of the first charging piles based on historical data of the plurality of first charging piles; based on the value of the first charging pile and the number of times of use of the first charging pile, at least one second charging pile is screened out from the first charging pile. The more electric pile that fills of use number of times is obviously more important, can fill electric pile through sieve its selection for the second, maintains it preferentially when maintaining the examination.
As an optional embodiment, at least one second charging pile is screened out from the plurality of first charging piles, and coverage area range indexes of each charging pile in the first charging piles can be determined based on historical data of the plurality of first charging piles; then based on the value of first electric pile and coverage area scope index, select out at least one second electric pile from first electric pile.
The coverage area range index is used to indicate a physical distance from another charging pile adjacent to one charging pile in the undirected network diagram to the charging pile or a size of a division range, and optionally, the division granularity of the division range may be a region of a city or may include a station. For example, if one charging pile belongs to an area a in a city, and the undirected network map includes 5 adjacent charging piles, 3 of the 5 charging piles are located in the area a, and 2 of the 5 charging piles are located in the area B, the coverage area range index of the charging pile may be determined to be 2, and the data indicating the charging pile may be a reference for error correction for the charging piles in 2 other areas.
