基于STC单片机的铁路信号半自动闭塞光缆传输器

摘要

The design of optical cable transmitter of semi-automatic block system is introduced,which adopts STC12C5A60S2 MCU as control unit,and be used in the field of railway signalling and communication.this paper describes the crossing backup circuit,safety AND-gate circuit and software structure related to railway safety.Moreover,It also solves the problem having an backup Application between electric cable and optical cable in semi-automatic block section,and improves traffic efficiency of the semi-automatic block route in our railway system.%文中介绍了以宏晶公司的STC12C5A60S2单片机为控制单元的用于铁路通信信号领域中的半自动闭塞光缆传输器的设计,并重点介绍了涉及铁路安全的交叉备份电路、安全与门电路以及软件结构。该系统解决了我国铁路现阶段存在的半自动闭塞区间电缆与光缆备份使用的问题,有效的提高了我国半自动闭塞区间铁路的行车效率。
