食堂灯光智能控制系统设计

Design of Intelligent Control System for Canteen LightingAbstractIntelligent lighting dates back to the 1980s.Into the 21st century,with the rapidimprovement of techology and the progress in service,intelligent lighting begin burgeon.Itsmarket coverage is growing.You can easily find intelligent lighting in public place such asoffice buildings ,hotels,stadiums and exhibition centers.Traditional lighting requires manualcontrol and is prone to energy waste.Intelligent lightinglighting has the timing,monitoring,management,remote control and other functions.Its purpose is to carry on the intelligentcontrol to the lighting fixture of our living environment,and create a comfortable,reliable,environmentally friendly lighting environment for us,Which can enrich our way of life.It isbelived that the future development of intelligent lighting will be full of hope andopportunities,and its market will involve all walks of life closely related to our lives.At present China's economy and society are developing at a high speed ,our quality oflife has been greatly improved,and energy supplies are also getting tighter.Under the guidanceof national strategy of harmonious society and sustainable development,green low-caebon lifeis becoming the pursuit of contemporary youth.We can't live without lighting .Lightingconsumes a lot of power,so how to achieve energy saving lighting has become a problem.Inorder to solve these problem,I designed the canteen lighting intelligent control systemexactly.The design uses LED lighting technology,infrared induction,light sensing technology,clock processing and other technologies to realize the canteen lighting intelligent.Thedesigned light detection circuit can detect and identify the light brightness in the canteen,while the infrared detection circuit can judge the area of the diners.Then it through the"brain"STC89C52 MCU automatically control the canteen lights on and off,adjust thebrightness of the lights.This design has completely changed the management mode of canteenlighting,greatly avoiding the waste of electric energy and reducing the burden of manpowermanagement.The lighting intelligent control system of the canteen has passed the physicaltest process,and can realize the functional requirements of the design,and can run stablyKeywords:STC89C52 single chip microcomputer,canteen lighting,Intelligent control
