Smart Home System Based On WeChat Control

With the accelerated pace of social life,traditional homes can no longer meet the needs of people's fast living,and smart homes built on the basis of traditional homes have developed rapidly.In smart home system,people use smart terminal to control the electrical appliances to make life more convenient.Selective closure of redundant electrical appliances makes the system more energy-saving.Sensors can sense the home state and make the home safer.In this paper,a smart home system controlled by Wechat is developed.The system adopts the system architecture of "client + cloud platform + hardware function module".Under this architecture,the hardware function module is composed of the developed micro-message program as the client,Tencent cloud server as the cloud platform,data information center,intelligent insertion and mobile security platform.At the end of this paper,the test of each functional module of the system is given.The test results show that the functions of the system can run normally.Under the framework of MINA,the system client software is constructed,which realizes remote control of intelligent insertion,real-time display of electrical energy data and sensor data,display of intruder images collected by mobile security platform,and realize man-machine dialogue.The MySQL database is designed by E-R diagram on the server side,and the server parsing hardware function module and client data are realized by PHP language.Through LoRa wireless network,the data information center transplanted with the operating system of ?C/OS-III and the protocol stack of LwIP is used as the system gateway to communicate with the server through ethernet.Through the design of the internal circuit of the intelligent slot,the functions of electrical control and electric energy acquisition are realized.Mobile security platform arrives at the designated location through sound guidance,and uses image sensor OV2640 to collect intruder images.In this paper,the overall scheme design of smart home,system hardware design and system software design are described in detail.Finally,after testing,the functions of the system are running normally and steadily.
