基于Zigbee的智能灯光控制系统设计

AbstractIn this paper,the characteristics of traditional lighting and modern lighting are studied comprehensively.By comparing the advantages and disadvantages,an advanced wireless intelligent control change scheme using Zigbee is given.That is to say,twoZigbee function boards are used in the system,one is imported into the photosensitive sensor and the thermo-infrared sensor,which are used for signal transmission,the other is connected to the relay module to receive signals and combine them.Control thelight to turn off.In modern society,the degree of automation and intelligence has beengreatly improved today,home intelligent management is likely to be the mainstreamchoice for people in the future.The main research object of this paper is family lighting.It mainly compares intelligent lighting with traditional lighting.Through the analysis of some serious problems in the current mainstream lighting control,such as backward lighting control mode,mechanical switch,low safety factor,poor comfort,complex wiring and so on.Because of the insufficiency of these control methods,energy is wasted enormously.Even in the mistaken area of control,there is no one in the room,but the lights are bright.In view of these shortcomings,it is necessary to do a further research and development on control.In this control mode,only when there are people in the room and the light is insufficient to light the required lights,but when there is no one in the room and the light is insufficient,the lights do not turn on.This control method can solve the problem ofwrong interruption and energy waste.In this paper,the function and control strategy of the whole control system will be introduced in detail.The software program design includes LED lamp initialization,photosensitive sensor initialization,PIR sensor initialization,protocol stack initialization,serial communication and so on.Finally,the feasibility and performance of the system will be tested under simulated real environment.Experiments show that the use of Zigbee wireless control can have agood control effect,and can significantly improve the energy-saving effect,improve the "unmanned light"problem.Key words:Zigbee,photosensitive sensor,pyroelectric infrared sensor,energy saving
