摘　　要：介绍了一种基于单片机和主控计算机的检测模块、控制模块及通讯模块,实施车辆编组站微机调度管理系统.单片机一方面通过光电耦合器检测轨道信号、信号机与转辙机状态信号,并将该信息通过RS232串行口上传到主控计算机;另一方面接受微机发出的控制指令对信号机和转辙机实施实时控制.利用VB开发了车站计算机联锁仿真系统,该系统接受调度指令,根据现场状况按照6502电气集中联锁逻辑关系和规则向单片机发出控制指令,从而实现了对驼峰、编组场及出发场的微机联锁控制.该系统在车辆编组站沙盘上进行了试验.The measurement, control and communication modules based on single-chip computer were introduced and employed to carry out marshalling station micro-computer dispatching system. The rail and state signals of the switch machine and signal system through the photo coupler can be detected by the single-chip computer and transported to host computer through RS232, the switch machine and the signal system are controlled according to the host computer by the single-chip computer. A station computer interlocking simulation system is developed with VB, which can accept and dispatch orders based on the spot condition according to logical relation and the rule of 6502 electric inter equipment. An simulation experiment of the microcomputer interlocking control is carried out on the hump of a marshalling and departure yard.
