[Abstract]:With the rapid development of science and technology in modern society, people's material living standards have been greatly improved, and people have higher requirements for living at home. With the requirement of multifunctional home life, the future home environment will be more and more comfortable, safe and intelligent. Therefore, intelligent home control system as a core technology to realize this new home life mode, its research meets the needs of the development of the times, and has important practical significance to further improve people's lives. This paper focuses on the establishment of ZigBee home network, power line carrier module, learning infrared remote control module and central controller in smart home control system. Firstly, the overall design requirements of the intelligent home control system are analyzed, and the design framework of the control system is given. Based on the analysis of the ZigBee technology and its network topology, the home network is built with DRF series ZigBee modules. The power line carrier module based on X-10 protocol is designed and implemented. The coupling circuit, zero detection circuit, power amplifier circuit and signal receiving circuit are given, as well as the modulation and demodulation program of X-10 protocol. The design scheme of learning infrared remote control module is put forward. The design of infrared receiving circuit, infrared transmitting circuit and flash memory circuit, power circuit and MCU core circuit are realized. The software program for learning and transmitting infrared carrier pulse is given. The hardware implementation scheme of the central controller in smart home is presented, and the related circuit diagrams such as power supply module, memory interface circuit and network interface circuit are given, and its software design is realized. Finally, several contents are tested and verified, and the related test results are given and analyzed. The test results show that the hardware and software work well and the functions are perfect, which can meet the application requirements of the control system.
