Design And Implementation Of Smart Home Control System Based On Websocket

With the continuous progress of society and the development of science and technology,people's quality of life requirements are getting higher and higher.Home intelligent has become one of the hot issues of social concern,it makes people's lives become more secure and convenient.On the one hand,the development of smart home industry can improve people's life quality,enhance power efficiency and reduce energy consumption.On the other hand,it can help people with mobility to barrier-free control the home appliances and improve their quality of life.This paper uses the wireless transmission,Internet and mobile phone applications and other technologies to provide the convenience of home appliances control,so that the users can remotely control the home device through a smart phone or web browser.In order to make the traditional home equipment can be controlled by a smart phone or a web browser,this paper designs a control device based on infrared remote control to control the home appliances.In order to facilitate user's operation,the paper develops an Android-based mobile APP on home appliances for short distance control.The main work of the paper is as follows:(1)Through the analysis of the application requirements of the system,the hardware and software functions of the system are divided.In the hardware system,design an infrared receiver module to learn traditional home appliances remote control signal.The module analogs remote control to control the home equipment using infrared emission module.The embedded wireless WIFI module provdes a data exchange channel for mobile phones,Web servers and hardware systems.The software system uses the IP configuration interface to establish the data communication with the hardware system.The operation interface is designed to select the control equipment and set the control parameters,realizing the flexible control of the home equipment.(2)According to the specific function of the system hardware,This paper respectively designs a control module based STM32 microprocessor,WIFI module,infrared receiving / sending module,storage module and other circuits.Through analying the work process,this paper develops the hardware system software program.(3)Based the Android Studio as the development platform,Java language and SQLite database technology are applied to complete the development of mobile APP control system.The system establishs a data transmission channel to achieve the short distance communication between mobile phone and hardware system.(4)WebSocket is adopted as the communication protocol between web browser and Web server.The functions of login,navigation,user information management,IP configuration,parameter setting and status monitoring are completed by using C # language,ASP.NET and EXT.NET.Test results show that the system has the characteristics of low cost,stable operation,beautiful pages,easy to operate and expand.It has strong practicality.
