摘　　要：本文结合地铁门控系统的应用实例,分析了采用PLC作为门控制器实现对地铁门控制的逻辑原理,并对基于CAN的高层协议CANopen和采用CANopen的列车通信网络进行了简单介绍,设计了PLC门控器作为CANopen列车通信网络从节点的方案,实现了通过网络对地铁门进行操作控制和状态监控、故障诊断等功能。With application example of metro door control system, the logical principle of using PLC to be door controller for implementing metro door control is analyzed in this paper. A compendiary introduction of high-level protocol based on CAN and train communication network which used CANopen protocol isgiven. Project of using PLC door controller to be a slave node in CANopen train communication network is designed for implementing door status monitoring, fault diagnosis and the control of metro door are realized via Network.
