| Abstract: | 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. |
