智能家居控制系统的设计与实现

广东东软学院本科毕业设计〔论文)AbstractWith the development of The Times,the level of production graduallyimproved,people began to pay attention to the quality of life,began to pursue amore convenient and simple,noble and intelligent way of life.On the other hand,the continuous development of IT technology,is no longer limited to a specificcompany and groups,IT infiltrates everyone's life,smart home came intobeing.However,the traditional smart home lacks the unified standard of thecountry,and the price is high,the operation is tedious and the service is single,which makes the smart home cannot be well popularized to ordinaryfamilies.Today,intelligent household reduces cost,simplify operation,imperative.The intelligent home control system designed in this paper USES infraredcommunication to control the STC89C52 chip,indirect control temperaturemodule,light intensity module,steering gear module,MQ2 smoke sensormodule,and let the LCD1602 display the corresponding action interface.Among them,both the light intensity module and MQ2 smoke sensor moduleadopt AD analog to digital conversion and SPI bus.Users can adjust thesensitivity of the fire alarm module by adjusting the smoke sensitivity threshold,which can well meet the needs of some people at home.The test results show that the system runs normally and the user can controlthe household normally through the remote control in the maximum range ofinfrared communication.Key words:smart home,STC89C52,Infrared communication,AD to digitalconversion,SPI bus
