一种基于微波感应的地下车库节能照明系统设计

Design of Energy-saving Lighting System for Underground Garage Based on Microwave Sensing

针对地下车库的照明系统基本采用人工控制,且24 h照明,灯管的损耗率非常高,维护工作量大,耗电量高等问题。本文设计了基于微波感应的地下车库节能照明系统。该系统由STC单片机、数字光强传感器、微波感应传感器、LED灯等组成。单片机根据装在地下车库入口处的数字光强传感器BH1750检测入口处的光照强度,调节入口处LED灯的亮度,光照强度由LCD1602显示。此外,通过微波感应传感器检测地下车库内车辆或人的移动,如果没有检测到车辆或人体移动,单片机控制LED灯的亮度为10%;如果检测到车辆或人移动,则调节LED亮度至90%,以达到节能环保的目的。

For the underground garage lighting system based on manual control,and 24 hours of lighting,lamp loss rate is very high,maintenance workload,high power consumption problems. This paper designs an energy-efficient lighting system for underground garage based on microwave induction. The system consists of STC microcontroller,digital light intensity sensor,microwave sensor sensors,LED lights and other components. According to the digital light intensity sensor BH1750 installed at the entrance of the underground garage,the light intensity of the entrance is adjusted to adjust the brightness of the LED light at the entrance,and the light intensity is displayed by the LCD1602. In addition,the microwave sensor sensor to detect the movement of vehicles or people in the underground garage,if no detection of vehicles or human movement,single-chip control LED lamp brightness of 10%;if the detection of vehicles or people move,adjust the LED brightness to 90%,In order to achieve the purpose of energy conservation and environmental protection.
