基于PLC的隧道照明控制系统设计

The design of tunnel lighting control system based on PLC

基于西门子S7-200PLC设计了隧道照明控制系统,采用了自动和手动两种控制方法。手动控制主要针对特殊天气状况或灯具设备维护时的照明,自动控制根据隧道外光照强度来对照明系统进行控制。通过PLC系统软硬件设计实现了隧道照明所需功能要求。本设计在照明的同时能够实现节能,并且保证司机人员的安全性与舒适性,具有一定的实际意义。

This paper designs tunnel lighting control system based on Siemens S7- 200 PLC , uses automatic and manual two control methods. Manual control mainly aimed at the special weather conditions or equipment maintenance of lighting lamps , automatic control according to the light intensity of tunnel outside to control lighting system. Through the hardware and software design of the it achieves the necessary functional requirements of the tunnel lighting. This design can achieve tunnel lighting as well as energy saving at the same time, and ensure safety and comfort of the driver personnel, so it has a certain practical significance.
