SPKS与门禁联动异常问题的原因分析及解决方案
Cause Analysis and Solution of Abnormal Linkage Between Staff Protection Key Switch and Access Control System
摘要
Abstract
In order to ensure the personal safety of operation and maintenance personnel in the track area,the Staff Protection Key Switch(SPKS)and access control system are usually linked in fully automatic driving lines.The SPKS which corresponds to protection zone needs to be activated before the operation and maintenance personnel enter the unmanned area from the manned area.Only after the protection zone is established,the access control system can be released for tap-and-go authorization,so that the staffcan use their access control cards to enter the unmanned area.When the SPKS is not activated,the access control cards are invalid.This paper elaborates on the abnormal linkage problem of SPKS,which causes access to be allowed when the SPKS is not activated.It analyzes the reasons for the induced voltage generated by the access control relay when the circuit is not connected,and proposes different solutions.It also analyzes the application timing of various solutions,and provides the guidance for the interface problem between SPKS and access control system in future projects.关键词
