Design And Implementation Of Smart Home Control System Based On Bluetooth Mesh And WiFi

With the vigorous development of my country’s social economy and science and technology,a large number of Io T devices have entered the market,especially the most popular smart home products,making people’s lives more convenient and intelligent.However,the mainstream smart home products currently on the market are smart products that are organized by each manufacturer and lack a unified standard,rather than a complete smart home control system.In addition,these products are becoming more and more costly and complicated to operate.At the same time,the products cannot communicate directly,and in an emergency,the data needs to be handed over to the gateway for centralized processing.Therefore,in view of the above problems,it is necessary to research and develop a smart home control system with low cost,simple operation and direct communication between devices.The thesis has done the following work:(1)By reviewing domestic and foreign literature,analyze the current research status of smart home control systems at home and abroad,analyze and summarize the practical problems existing in current smart home control systems.(2)Analyze the requirements and functions of the current smart home control system,divide the system into terminal nodes,smart gateways,and cloud servers,and subdivide the functions to be realized,select key technologies for application scenarios,and finally establish Local networking based on Bluetooth Mesh,Wi Fi technology directly connected to the cloud,and the overall selection and framework of cloud servers.(3)According to the requirements and framework of the smart home control system,the functions of terminal nodes,smart gateways,and cloud servers are realized through software and hardware design,including remote control and monitoring,and collection of temperature and humidity,light intensity,and human body infrared sensing data.And analyze,store,display and forward these data.Design a custom transmission model and data frame for Bluetooth Mesh networking.(4)Carry out detailed software and hardware tests on the system,including power supply part tests,data acquisition tests,wireless communication technology function tests,cloud server function tests,user display interface tests,and mobile terminal software tests.The data storage and display effects are normal,and the test results meet the expected requirements.The design of the smart home control system based on Bluetooth Mesh and Wi Fi in this thesis can realize the user’s monitoring and control of equipment,and can directly exchange data between different equipment,with good communication performance,reliable operation,and low maintenance cost.I hope this thesis can provide new ideas for the development of smart home.
