Design And Implementation Of Smart Home System Based On Cloud Server ECS And ZigBee

In recent years,with the improvement of people's living standards and the development of Internet technology,the state has mentioned the concept of "green city" and "smart city" to a new height,and the smart home industry is booming.However,the existing smart home products on the market lack:uniform standar-ds and platforms,and have low security,poor flexibility,and cumbersome user operations.Therefore,the embedded study of smart home systems has very important application value.Firstly,this thesis compares and selects short-range wireless communication scheme and long-distance wireless communication scheme,and deeply studies some key technologies commonly used in the home system,and finally determines the overall structure of the smart home system based on the cloud server ECS and ZigBee.The rdesign of the three modules of intelligent gateway,home personal area network and remote communication were completed from both hardware and software.In the intelligent gateway module part,this thesis designs a home gateway with ESP8266 chip as the core of control by selecting the commonly used gateway chip,and programming two-way communication between gateway and cloud seirver and gateway and coordinator nodes;Based on the in-depth study of ZigBee technology,this thesis designs a terminal acquisition and control system including temperature and humidity sensors,light sensors,gas sensors,infrared sensors,relays and stepper motors.Based on the Z-Stack protocol stack,the software design of ZigBee coordinator node and ZigBee terminal node is completed.In the remote communication module part,this thesis deeply studies the application of cloud server ECS in smart home system.Based on Android,the client app is developed based on MFC developed the server application software,and finally realized the remote communication function of the smart home system by means of the public network environment of the cloud server ECS.Finally,the system is tested in the laboratory environment.The test content includes four parts:login module function test,environmental parameter acquisition module function test,intelligent security module function test and home appliance control module function test.The test results show that the system successfully achieves the expected goal,and is stable and reliable,easy to operate,and has certain market application prospects and practical value.
