摘要
为提高铁路道口报警系统的稳定可靠性,将微机连锁源程序与道口控制程序融合后,设计一种微机联锁信号控制铁路道口自动报警系统。分别介绍单股道铁路道口和2条股道以上铁路道口的系统硬件电路图、工作原理和软件设计方法。系统试运行阶段没有出现任何错误和异常,现已推广使用。
In order to improve the stability and reliability of current railway crossroad automatic alarm system,a railway crossroad automatic alarm system controlled by PLC and computer is designed based on the integration of micro-computer interlocking source program and crossroad control program.Design method for hardware and software of single line railway crossroad system and two or more lines railway crossroad system is introduced.Test results show that the system has high reliability and is worth spreading.
