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.
A detection module, control module and communication module based on single-chip computer and main control computer are introduced, and the computer scheduling management system of the vehicle marshalling station is implemented.On the one hand, the single-chip microcomputer detects the signal of track, signal and switch machine state signals through photocoupler The information is uploaded to the host computer through the RS232 serial port, and on the other hand, the control commands issued by the microcomputer are used to control the signal machine and the switch machine in real time.The station computer interlocking simulation system is developed by using VB, , According to the field conditions in accordance with the 6502 electrical centralized interlocking logic and rules issued to the microcontroller commands to achieve the hump, marshalling yard and starting the microcomputer interlock control system in the vehicle marshalling station sand table was tested.
