Research And Implementation Of Smart Home Control System Based On ZigBee Technology

Because of the universal problem of complex installation, high power consumption,and poor user experience,the traditional smart home market penetration is not high.By the analysis and comparison of current mainstream smart home technology,the ZigBee wireless communication technology which overcome the drawbacks of the cable technology is used in the research and design of the Intelligent home application,and a lightweight smart home system design scheme based on ZigBee technology is proposed.ZigBee wireless communication network is built in inner home, the data information of the terminal equipment(door and window magnetic terminal, waterlogging terminal, temperature and humidity terminal, intelligent socket terminal) is uploaded to the user through MQTT technology, which enables users to obtain real-time monitoring information and carry out intelligent control,meanwhile provide users with convenient and efficient smart home experience.The system uses TI CC2530 ZigBee chip as the ZigBee wireless network transceiver module, to design the hardware part of nerworking module-ZigBee coordinator, as well as four terminals,including door and window magnetic terminal,waterlogging terminal, temperature and humidity terminal, intelligent socket terminal.The software part mainly includes the establishment of ZigBee network,the internal communication of ZigBee network, ZigBee terminal data acquisition,ZigBee network and the external network communication and so on, the ZigBee technology will be described in detail in this paper.The innovation of the system : when ZigBee terminal equipments fail to connect to the ZigBee wireless network,energy consumption is still existed, bring the system unnecessary energy consumption.In order to improve the system performance, this scheme improves the way of joining ZigBee network when terminals disconnect with the coordinator, and reduces the system power consumption efficiently.
