基于CPLD的隧道灯控制电路设计

Tunnel lamp control circuit design based on CPLD

随着社会的发展,交通越来越便利,对于多山的贵州地区,想要实现交通的便利,隧道是必不可少的工程,而其中隧道灯的节能控制就是人们不可忽视的问题。在实际生活中隧道灯的节能控制的方法有很多,这里采用的是CPLD来实现这一功能。利用CPLD设计的电路可对隧道照明区域进行分段控制,做到"车近灯亮,车过灯灭",消除"黑洞效应"和"白洞效应",为驾驶员提供良好的驾驶环境,提高行驶安全性。同时,"车近灯亮,车过灯灭"的工作方式改变了现有隧道灯24h常亮的工作方式,节约大量电能。

With the development of society, more convenient for mountainous areas in Guizhou, to achieve ease of transport, tunnels are essential engineering and energy saving control of tunnel lighting is the problem not to be ignored. Tunnel lights in real life there are many ways of energy-saving control, the CPLD is used to implement this functionality. Using CPLD to design circuits the control of tunnel lighting zones, so that ＂Near car lights, car lights off too＂ to eliminate the ＂black hole effect＂and the＂white hole effect＂, providing drivers with good driving environment, improve driving safety. Meanwhile,＂Near car lights, car lights off too＂way of working changes the existing tunnel lamp 24 h always works, saves a lot of power.
