At the moment, the reverse proxy server matches the charging pile data information of the charging request message with the system relation table to obtain a background server where the charging pile is located, and then sends the charging request message to the background server where the charging pile is located, so that the background server where the charging pile is located analyzes and verifies the charging request message. In order to ensure the charging safety, the charging request is verified, for example, whether the vehicle to be charged is matched with the charging pile or not is verified, and the verification data can be specifically set according to the actual situation.
And the reverse proxy server also sends a verification result returned by the background server where the charging pile is located to the control device of the charging pile so that the control device controls the charging pile according to the verification result.
When the verification is passed, the control device controls the charger to start to charge the vehicle to be charged; otherwise, it is not started.
After the charging of the charging pile is finished, the control device generates a charging completion message according to the vehicle information of the vehicle to be charged, the data information of the charging pile, the charging operation data and the like, and sends the charging completion message to the reverse proxy server, so that the reverse proxy server matches the system relation table according to the charging completion message to obtain a background server where the charging pile is located, and sends the background server where the charging pile is located to the background server where the charging pile is located for storage. The charging data of the charging piles are stored through the background server, so that the data tracing of subsequent maintenance and management is facilitated.
According to the invention, the plurality of charging piles are respectively stored on the corresponding background servers, and the distribution is realized through the SLB load balancing server, so that the effective and ordered management of the charging piles is ensured, and meanwhile, the timely response of the background servers can be ensured.
Preferably, each charging pile is further provided with a communication module. The control device is accessed to the network through the communication module and is further in communication connection with the reverse proxy server through the network.
Preferably, the embodiment further includes a mobile terminal, and the mobile terminal is in communication connection with the reverse proxy server through a network to implement data interaction with the background server. For example, a user can query data information of each charging pile through the mobile terminal, query the working state of the charging pile and the like. Preferably, still be equipped with display device on every fills electric pile, with controlling means electric connection for the operating condition and other data that show and fill electric pile. The working state includes, for example, charging, waiting for charging, charging completion, and fault abnormality. The working state of the charging pile is displayed for the user through the display device, and misoperation of the user is avoided.
Preferably, in the charging process of the charging pile, the control device further generates charging data at regular time and sends the charging data to the corresponding background server through the reverse proxy server, so that the corresponding background server checks the charging data of the charging pile.
When a background server where the charging pile is located detects charging abnormality, the reverse proxy server feeds back a detection result to a control device of the charging pile, and the control device suspends charging of the charging pile so as to avoid the occurrence of the abnormality; meanwhile, charging abnormal information can be generated to perform early warning according to a preset early warning mode, such as timely maintenance through related workers and the like.
