摘要
现代城市的发展造就了数以万计的地下车库。目前车库的照明光源基本采用T8或T5直管荧光灯,灯光照明的控制方式大部分均采用集中人工控制的方式,由值班员进行操控。地下车库全天候24小时持续照明,灯管的损耗率非常高,维护工作量大,耗电量极高。针对以上问题,设计一种专用于地下车库的节能照明系统具有非常重要的意义。本文的设计是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、微波感应传感器和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。LED灯亮度通过PID算法和PWM技术控制。最后通过实验证明,系统达到预期的节能效果,可为相关行业提供有益的借鉴。
The development of modern cities has created tens of thousands of underground garages. At present,the lighting source of the garage is basically using T8 or T5 direct tube fluorescent lamp,and the control mode of light lighting is mostly controlled by centralized manual control,which is controlled by the duty officer. The underground garage has 24 hours of continuous illumination,and the wastage rate of the lamp is very high. The maintenance workload is large and the power consumption is extremely high. In view of the above problems,it has a great significance to design an energy-efficient lighting system dedicated to underground garage. The design of this paper is based on the microwave induction of the underground garage energy saving lighting system. The system is composed of STC microcontroller,digital light intensity sensor,microwave induction sensor,LED lamp and so on. According to the digital intensity sensor BH1750 which is installed at the entrance of the underground garage,the MCU detects the light intensity at the entrance,and regulates the brightness of the LED lamp at the entrance,and the intensity of light is displayed by LCD1602. In addition,the vehicle or human movement in the underground garage is detected by the microwave induction sensor. If the vehicle or human movement is not detected,the brightness of the LED lamp is 10%. If the vehicle or the person is moved,the brightness of the LED is adjusted to 90% to achieve the goal of energy conservation and environmental protection. The luminance of the LED lamp is controlled by the PID algorithm and the PWM technology. Finally,through the test,the system achieves the expected energy saving effect,which can provide useful reference for the related industries.
