基于PLC的火车站站台车厢号指引系统设计

Design of Train Station Platform Carriage Number Guidance System Based on PLC

火车站站台采用地标颜色的方式来引导乘客乘坐的车厢号,存在严重不足,为此,应用可编程控制器PLC技术和动态扫描数码管显示的原理,设计了一种基于PLC的火车站站台车厢号指引系统。研制的样机经过模拟测试,一键实现对进站列车车厢号分布情况进行编号编码,操作简单、准确高效,车厢号以数字形式显示出来,直观醒目、极易分辨,替代现有的“颜色地标”,车站信息化技术更加智能化、人性化。

The railway station platform uses landmark color to guide the carriage number of passengers. This guidance method has serious shortcomings. So a kind of guiding system of train station platform carriage number based on PLC is designed by using PLC technology and the principle of dynamic scanning digital tube display. Through simulation test, the developed prototype can code the carriage number distribution of incoming trains with one key. The operation is simple, accurate and efficient. The carriage number is displayed in digital form, which is intuitive, eye-catching and easy to distinguish. Instead of the existing "color landmark",the station information technology is more intelligent and humanized.
