绿色节能道路照明系统的研究

Research on Green Energy-Saving Road Lighting System

深夜道路上没有车辆在行驶时,路灯继续开着,会大量地浪费电能,因此设计一款绿色节能道路照明系统来解决这一问题。根据不同时间段车流量不同的情况,对该系统设计了三种模式:第一种是车流量较大的时间段,18点到23点,这个时间段内路灯都正常亮;第二种是23点到凌晨2点以及凌晨4点到凌晨6点,车流量较少,路灯采取一隔一的点亮。第三种是凌晨2点到凌晨4点,车流量极少,路灯采取首尾灯亮,中间灯熄灭,当有车通过时,路口的光电传感器检测到有车,PLC程序运行,中间的路灯一隔一亮点亮,当道路尾端的光电传感器检测到汽车通过后,路灯熄灭,恢复到首尾灯亮的状态。这套系统可以大大节约用电,起到绿色环保的作用。

There are no vehicles on the road at night,the street lights are still on,there will be a waste of electrical energy.In order to solve this problem,a green energy-saving road lighting system is designed.According to the different traffic flow in different time periods,three modes are designed for the system.The first one is the time range from 6 pm to 11pm.When the traffic flow is large,and the street lights will be normally bright during this time period.The second one is from 11pm to 2 am and from 4 am to 6 am.When the traffic flow is less,the street lights will lit one by one.The third one is from 2 am to 4 am.When the traffic volume is very small,the street light will be illuminated by the first light and the last one,and the middle light will be extinguished.When there is a car passing,the photoelectric sensor of the intersection will detect that there is a car and the PLC program will run,and the middle street lamp is separated.When it is lit,the photoelectric sensor at the end of the road will detect that the car has passed,and then the street light will go out and return to the state that the first light and the last one are on.This system can greatly save electricity and play an important role in green environmental protection and energy conservation.
