摘要
本文介绍了基于PLC(可编程控制器)控制的轨道交通系统站点语音提示及动态显示系统的设计。包括该系统的控制原理、编程设计、软硬件的组成设计等。使用该系统可以让乘客更加清楚的听到和看到该轨道交通系统现行方向、现行站点和将要达到的站点。对不同路线或者站点的增加都可以在系统中修改。整套系统性价比高、安全可靠。能够为不熟悉线路者或听视力不好的乘客提供很好的便利。
This paper introduces the based on PLC（programmable controller）control bus site voice prompt and dynamic display system design. Including the system control principle, programming design, software and hardware design, etc. The system can let the passengers more clearly see and hear the bus current direction, the current site and will achieve site. For different route or the increase of the site can be modified in the system. A complete set of system cost-effective, safe and reliable. To those not familiar with the line or listen to eyesight passengers provide very good convenience.
