Intelligent multi-communication system and method for electromobile alternate current charging pile in mountainous environment

Abstract

The invention relates to an intelligent multi-communication system and method for an electromobile alternate current charging pile in a mountainous environment and belongs to the technical field of new energy and communication. The intelligent multi-communication method is combined with various communication modes including 230 MHz wireless private network communication, PLC communication and GPRS / CDMA wireless public network communication, and mainly comprises a master station layer, a communication channel layer and an alternate current charging pile communication unit layer, wherein the master station layer is in charge of data management and application; the communication channel layer performs message identification and environment judgment and selects the corresponding communication modes; the alternate current charging pile communication unit layer is in charge of data sending and command execution in the different communication modes. The intelligent multi-communication method comprises the following steps: S1: message triggering and initializing; S2: message identification: the master station layer identifies power grid transaction information and platform monitoring data messages from acquired object information; S3: communication environment judgment: a communication environment value is calculated and judged; S4: selection of the communication modes according to judgment results.

Description

technical field [0001] The invention belongs to the technical field of new energy and communication, and relates to an intelligent multi-communication system and method for an electric vehicle AC charging pile in a mountainous environment. Background technique [0002] Electric vehicle AC charging pile is to provide safe and reliable AC power for on-board chargers. It is used for AC charging of public, household, rental or residential property electric vehicles. It is easy to install and can be vehicle-mounted, portable, wall-mounted and floor-mounted. The AC charging pile is composed of a pile body and an electrical module. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging electric vehicles. The communication of the charging pile mainly involves three aspects: communication with the distribution station, communication with the remote control platform, and communication with the electric ...

AI Technical Summary

Problems solved by technology

On the other hand, the GPRS public network has good concurrency, but the operation quality of the public network communication depends on the mobile operator to a considerable extent

However, the wireless communication technologies of 230MHz private network and GPRS public network have communication blind spots

The three communication methods have their own advantages and disadvantages. Only by dynamically selecting, adjusting, and combining according to the communication environment can the maximum benefits be brought into play.

However, PLC communication is not suitable for the existing high-bandwidth requirements due to low spectrum utilization, short transmission distance, and large interference. It needs to be combined with other methods to provide reliable and stable communication guarantees.
