The Prompting System Design of Automatic Route Information for Railway Operations

为保障无电气联锁道岔线路整备场作业调车安全,以STC10F08单片机作为现场控制器核心,利用磁电角度传感器,对道岔正反位状态进行检测,经过逻辑分析后,驱动LED显示屏为扳道人员及乘务员提供股道指示。现场控制器通过RS485总线与调度室计算机进行通讯。以Labview开发的复视软件,能够直观显示线路状况,且可以对通讯及现场控制器工作异常实现判断,系统安装后,使用效果良好。

To guarantee the security of railway operations in the shunting preparation field without electrical in terlock turnouts, the proposed design chooses the STC 10F08 microcontroller as the field controller and detects the positive or negative state of turnouts through the magnetic angle sensor. With logical analyses, the LED can be driven to display station track information for switchmen and crew. The field controller communicates with the computer in the dispatch room through RS485 Bus. The diplopic screen is developed on the Labview soft ware platform, which clearly displays route information in the form of graphs and detects unusual circumstanc es of the communication or onsite controllers. The trial results show that all the functions are normal with fa vorable effects.
