广佛线信号系统与屏蔽门系统接口分析

屏蔽门的控制需要信号提供相应的接口,以广州地铁广佛线为例描述了西门子CBTC信号系统和PSD系统之间的接口设计,介绍了CBTC信号系统与PSD的接口功能、电气接口和电气接口的操作。接口功能方面涉及CTC模式下的接口任务、联锁的接口任务和系统信息传递情况,电气接口方面提到各种运行状态下的继电器接口及简要分析了其工作原理及电路连接图,另外在接口操作方面还介绍了信号系统与PSD系统之间的开关门时序、开关门真值表和动作时间等内容。

Analysis of the Interface between Signaling System and PSD System

PSD controlling requires the signal system to provide appropriate interfaces.In the case of Guangzhou—Foshan metro line,the author describes the interface design between the PSD system and the Siemens＇ CBTC signaling system,and describes the functions of the interfaces,electrical interface as well as the operation of the electrical interface.The interface functions involve in the interface task under CTC mode,the interlock interface tasks,and the transfer of system data.The electrical interfaces involve in the relay interfaces in a variety of operating states and brief analysis of the working principles and circuit connection diagrams.The interface operations involve in the timing sequence,the truth table,and the operating time of door opening and closing.
