Design And Realization Of Intelligent Home System Based On Wireless Communication

With the rapid improvement of China's productivity level,the people's material and spiritual living standards have also become increasingly rich.In recent years,the convenience of life brought by the development of science and technology has been particularly prominent.Among them,smart home products are popular with the masses because of their closeness to life.However,the current smart home market is often relatively high-end in the positioning of related products,and the threshold for user experience remains high.In order to improve this situation and increase the penetration rate of smart home products in Chinese households,a smart home system that is inexpensive and easy to construct and maintain is designed.The communication core technology of the smart home system is a combination of multiple wireless transmission methods,mainly involving ZigBee,Wi-Fi,and network communication technology.The overall system is divided into three parts.The first part takes the STM32 single-chip microcomputer as the core and sequentially develops the single-chip peripheral circuits,ZigBee coordination,ZigBee terminal circuits,PT100 temperature sensors,and 42-type stepper motor terminal circuits to implement various devices within a short distance Signal communication between gateways.At the same time,a routing optimization algorithm was introduced in ZigBee communication to increase the communication distance and coordinate system power consumption.The second part uses a third-party cloud server,applies web development and database development technologies,and cooperates with related network communication technologies to provide a terminal control platform of a browser carrier to achieve remote home control and environmental information collection.The third part is used to connect the first two parts to communicate the cloud service information with the specific equipment installed in the home.It is mainly composed of ESP8266 communication circuit,network router,and computer.In order to better test and detect the signal flow in the communication process,the upper computer page and digital display technology are used to display the system signal.The overall system provides information interaction between home information and user operations,and switches to automatic control mode when the user is not performing operations.This design completes the overall software design,hardware design,web page function design,and host computer design of the smart home system.Finally,after hardware and software debugging,a variety of low-power wireless transmissions work normally,terminal sensor and device model data are accurate,and test routing algorithms obtain improved power consumption results.Mobile terminals such as mobile phones can remotely operate terminal devices and host computers in 4G network environments The cloud data is displayed normally,and the database form is complete.
