摘要
为深入剖析进站信号机点灯电路的工作原理,基于AT89C51单片机设计模拟控制电路,以按钮开关逻辑组合模拟电路的联锁条件,实现办理进路、开放信号功能。仿真验证结果表明,系统能够正确模拟进站信号机点灯电路相关功能。模拟系统可以服务于车站信号的实训、实验等场景。
In order to analyze the working principle of the lighting circuit of the home signal,the design of analog control circuit based on 51 singlechip microcomputer and the interlocking condition of the logic combination of the button switch are implemented to realize the route setting and the open signal function.The simulation results show that the system can correctly simulate the relevant functions of the lighting circuit of the home signal.The simulation system can serve the scenes such as the practical trainings and experiments of the station signals.
