An Improved Safety Control System for Rail Transit
Abstract— An improved safety control system is designed and is composed of the reference signal
generating unit, the processing unit, the output unit, and the dynamic & static read-back unit. A
synchronization vote mechanism within dual channel is adopted to realize the safe and reliable output for this
system. The processing unit is composed of a short-time detection pulse generation module, an output
module, a short-time pulse decoding module and a static decoding module for realizing short-time detection
pulse generation and decoding of the extraction signal. Testing results present this system has the
characteristics of fast detection, high fault detection coverage and low failure rate, which can meet the
requirements of safety and reliability in rail transit field.
