The invention discloses a communication method of a split type charging pile, which comprises the following steps: judging the network port state of a redundant management node or a redundant forwarding node according to the network port information of the redundant management node and the redundant forwarding node, matching a corresponding port after response, and switching the corresponding network port state to form a link to send a corresponding message; according to the invention, the link switching time is shorter, the link switching is responsible by the charging host and does not depend on the reporting or state transition of each device in the link, the maximum link switching time is determined by the heartbeat timeout time and can be set to be a threshold value less than the minimum link switching time of the RSTP protocol, and in addition, compared with other redundancy protocol schemes, the maximum link switching time can be set to be a threshold value less than the minimum link switching time of the RSTP protocol. According to the invention, the method is simpler to implement, does not need to support an additional redundancy protocol, and in short, the charging host and the charging terminal are connected by using the redundancy link, and a specific technical scheme is adopted, so that shorter link switching time and a simple implementation mode are realized.

    本发明公开了一种分体式充电桩的通信方法,包括根据冗余管理节点和冗余转发节点的网口信息,判断冗余管理节点或冗余转发节点的网口状态,响应后匹配对应的端口,并切换相应的网口状态后形成链路进行相应的报文发送;本发明的链路切换时间更短,其中链路切换由充电主机负责,无需依赖链路中各设备的上报或状态迁移,最大链路切换时间由心跳超时时间决定,可以设置为小于RSTP协议最小链路切换时间的阈值,此外,相比其他冗余协议方案,本发明的实现也更加简单,无需支持额外的冗余协议,总之,本发明通过使用冗余链路连接充电主机与充电终端,并采用特定的技术方案,实现了更短的链路切换时间和简单的实现方式。
