Design And Implementation Of A Smart Home System Based On Raspberry Pi

With the development of science and technology,the home ecosystem has become increasingly intelligent.The smart home control system makes it convenient for people to control home appliances,collect living environment information,and ensure home environment security.Smart home-related products are also developing rapidly.The major smart home-based technology companies occupy the market,continuously increase research and development,promote various types of smart home system products with gradually-complete functions,and continuously improve the smart home technology sense and comfort.The feeling makes people's home environment more intelligent.The paper completed a smart home control system based on the Raspberry pie,designed and implemented four functions of home security,home environment monitoring,information appliance control,smart speaker,and designed and implemented a WeChat,Web-based host computer.In addition,face recognition,language recognition and other characteristic technologies are integrated into the family authentication feature of the face recognition function and the smart speaker,and a set of functional smart home systems is constructed.The hardware platform of the control system uses the Raspberry Pi 3rd generation B development board as the main site,and the Arduino UNO R3 development board is used as the slave site to transfer data through the ZigBee module and the primary site.the software platform using embedded Debian as the operating system,the use of Python language control program written and docking WeChat public number development platform,Use MySQL database to store collected data,use Html?JavaScript?PHP language and JpGraph driver gallery to write web-side display interface,to achieve multi-platform display information and control home ecological environment,to maximize the convenience of people's lives.Based on the above functional requirements and development environment,the dissertation completes the deployment of system software environment and the construction of actual hardware peripheral circuits,and writes and debugs the software programs on the developed platform.The results of project development show that the design of the system is reasonable and the functions and indexes basically meet the functional requirements of this paper.The design of the Raspberry Pi-based smart home control system improves more functions,reduces the manufacturing cost and improves People's life and entertainment,in the existing smart home control system to achieve a program to put forward a new solution.
