摘要
介绍深圳地铁一期项目中信号系统与屏蔽门之间接口的基本工作原理;分析该接口电路主要存在的问题,原因是原来的接口电路中屏蔽门一侧的回路接触电阻较大且不稳定,从而使得由屏蔽门系统发给信号系统的屏蔽门关闭锁紧信号不够稳定;提出切合实际并稳定有效的屏蔽门关闭锁紧回路接口的优化方案。
The fundamental working principles of the interface between the signaling system and Platform Screen Door （PSD） system in Shenzhen Metro Phase 1 Project are presented and the problems in the circuit of this interface are analyzed. It is concluded that the great and unstable contact resistance result s in the instability of the signal of closed and locked interface circuit to signaling system. The author gives the optimized solution for a practical, stable and reliable interface of PSD closed and locked circuit.
