The Analysis And Design Of The Inspection And Control System For Smart Home

This topic comes from the Lenovo Home New project, which aims to establish a complete ecosystem of Smart Home. It has a great significance for AI control in Smart Home. My mainly responsible is the analysis and design of the inspection and control system for Smart Home in the project. The analysis and design of the inspection and control system for Smart Home based on housing, in combination with wireless communication technology, sensor technology and embedded technology, to achieve the automatic detection and control of electrical devices in the residence.Paper comprehensive analysed and designed the inspection and control system for Smart Home, analysed the requirements of this system, studied the linkage control strategy, the focus is to increase detecting functions, improve the wireless connection compatibility issues, improve the intelligence level of smart home detection and control system.According to the analysis of the smart home control system in the market, accessed to a large number of literatures and materials, discussed the wireless communication technology in depth to avoid the shortcomings of the smart home control system. Improved the wireless connection, which is compatible with the three communication protocols of ZIGBEE, BLE and WIFI.To meet project requirements, to achieve detection and linkage control functions, using many kinds of sensors, such as PM2.5, formaldehyde, temperature and humidity sensors to detect the residential environment. Choosing AM3354 chip of TI Company as control core, processing detected data and control electrical equipments, blackberry Q5 as the human-computer interface, synchronizing the data to the mobile client and the cloud through wireless communications. The cloud server analyses users’ using habit to realize the automatic control of electrical equipment.In this paper, according to the project requirements, selected suitable electronic components. Hardware part designs the circuits of the controller AM3354 circuit, power circuit, liquid crystal display(LCD) circuit, sensors detected circuit,wireless communication(WIFI, BLE, ZIGBEE) circuit, through Multisim software simulation and actual circuit tested.Finally, the hardware and software of the system has carried on the comprehensive test, and the interconnection, detection and control of smart devices are realized. Detection data of environment sensors has process, displayed and transmitted well. Analyze the testing results, basically meet the design requirements and the desired result of the design.
