轨道交通信号系统与车辆接口的几个常见问题探讨

Common Issues of Interface Design between Rail Transit Signaling System and Vehicle

在实施列车自动控制系统的项目中,信号系统与车辆的接口设计是必不可少的重要一环。业主、信号供应商和车辆供应商通过设计磋商来确定轨道交通信号系统与车辆的接口设计方案,其中涉及到客户、信号与车辆供应商的责任划分、接口定义和设计理念的融合。对实际项目中信号系统与车辆接口经常遇到的保障紧急制动率、安全继电器接口和旁路电路设计等问题进行了探讨,以供接口设计方案的确定作参考。

In railway automatic train control（ATC）project,the design of interface between signaling system and vehicle is an important and indispensable phase. Customer,signaling and vehicle suppliers will define the interface design through design liaison meeting together. In this meeting,the responsibility scope of each party,the specification for interface and the tradeoff of design concepts will be discussed. By analyzing the examples of GEBR often seen in real projects,the design of interface between signaling system and vehicle,the safety relay interface and so on are discussed.
