Research on a smart home system based on short-range wireless communication technology

With the development of economy and the continuous progress of science and technology, people are increasingly pursuing a highly safe and comfortable living environment and intelligent and diversified information services. Smart home system is generally based on old and new houses, and through a series of wireless wired communication technology, network integration technology and automation application technology, a family management system composed of environmental data collection, terminal control of household appliances, security alarm and other related aspects is established, thus providing a highly integrated and comfortable home living space. In line with this trend, we designed DCA-3000 smart home system, which is suitable for the middle and high-end market. This system can realize the functions of home-based security and remote meter reading. However, the Zigbee communication module, a data acquisition sub-node, adopted at that time, has high power consumption and no sleep function, so it is difficult to supply power with batteries for a long time. On the basis of analysis and design, a temperature acquisition subsystem of smart home wireless network based on ZigBee technology is implemented. Through the implementation of the subsystem and relevant experimental tests, the feasibility of the overall scheme design of the smart home system in this paper is verified. The network composition based on ZigBee technology can meet the requirements of the smart home system.
