PLC communication gateway concentrator in electric vehicle intelligent charging communication system

The utility model relates to a PLC communication gateway concentrator in an electric automobile intelligent charging communication system. The PLC communication gateway concentrator comprises a CPU, adisplay screen module, a 4G and GPS module, a WIFI module, an Internet module and a power line carrier communication chip. The CPU is connected with the display screen module through a TTL interface.Wherein the CPU is connected with the 4G module and the WIFI module through USB interfaces, and is connected with the Internet module and the power line carrier communication chip through Ethernet interfaces, an embedded Linux operating system is built in the CPU, and the system is connected with the display screen through RGB signals of a TTL interface. The system has the advantages that: 1) thePLC communication gateway concentrator realizes information statistical summary of a single station by using a GPAV technology through power line transmission, and reports the information statisticalsummary to a cloud end in a unified manner, so that the problem of network wiring in medium and large electric vehicle charging stations is solved; and an OCPP communication protocol stack is built in, and multiple remote management functions can be conveniently realized by using a network communication technology. And a plurality of networking modes (4G, WIFI and Ethernet) are adopted to performdata interaction with the OCPP cloud platform, so that the networking stability can be ensured. 本实用新型涉及一种电动汽车智能充电通信系统中PLC通信网关集中器，包括具有CPU、显示屏模块、4G及GPS模块、WIFI模块、因特网模块、电力线载波通信芯片；CPU通过TTL接口与显示屏模块连接，通过USB接口与4G模块、WIFI模块连接，通过以太网接口连接因特网模块、电力线载波通信芯片，所述CPU内建嵌入式Linux操作系统，系统通过TTL接口的RGB信号与显示屏连接。优点：1）PLC通信网关集中器通过电力线传输，利用GPAV技术实现单一站点的信息统计汇总并统一上报到云端，解决了中大型电动汽车充电站点中的网络布线问题。内建OCPP通信协议栈，利用网络通信技术可便捷实现远程多项管理功能。有多种联网方式（4G、WIFI、以太网）与OCPP云平台进行数据交互，保证联网的稳定性。
