Design And Implementation Of Smart Home Control System Based On Embedded System

With the rapid development of science and technology and the rapid development of social economy,people’s living standards are constantly improving,people’s living demand for living not only stay in the stage to meet the basic needs of survival,but also have a higher level of appeal for home automation,humanization,intelligent.At present,the intelligent home system is still in the development stage.Most of the smart home systems on the market still have a series of shortcomings like functional single and too expensive,so aiming at these shortcomings,design a smart home control system based on embedded,and the related research was studied as following:(1)This paper summarizes the overall design scheme of intelligent home system,and introduces the design scheme of terminal equipment,the design scheme of the client and the choice of communication mode.(2)Through comparison and analysis of several basic motion target detection algorithms,select the ViBe algorithm as the moving target detection algorithm,make improvements aimed at the defect of ViBe algorithm.(3)Through the analysis of the functions and requirements of the intelligent home system,the design of the hardware circuit of the equipment terminal is mainly the design of some basic circuits(power supply and reset circuit,USB interface circuit,serial interface circuit)and the circuit design of the execution module.Completed the embedded Linux operating system structures,including the establishment of cross-compiler environment,U-Boot porting,kernel cutting,file system production.(4)Completed the design of intelligent home system software.Software development is divided into three parts,one is the central terminal software design,which is mainly temperature and humidity sensor drive,curtain-driven development,and application design,including temperature and humidity data acquisition procedures,curtain control procedures,electrical control procedures,video capture procedures;third,the client software design,it is mainly the preparation of human-computer interaction interface,the preparation of user-side control programs,and the preparation of moving target detection programs.(5)Eventually,the experiment is preformed after the building of the smart home system platform.Experimental results show that as long as the computer is in the Wi-Fi wireless network,the user can remotely check the temperature and relative humidity of the home,control the curtains,video surveillance for home,and control the air conditioning on the computer.
