家用电器的网络化是家庭网络化的基础,也是智能家电技术发展的必然趋势。文章以无线射频收发芯片作为家电控制网络底层实体传输媒介,构建了集中式家电近距离无线控制网络星型拓扑结构,并以室内温湿度信息为控制对象,设计了近距离无线收发模块、网关PC无线通信接口板等软硬件模块,并自定义了串口通信协议,改进了CRC-16冗余算法,完成了家电无线控制网中的温湿度集中监控及Internet接入试验,验证了基于近距离无线技术的家电集中控制方法的可行性、易用性。
Network appliance is the basis of home networking, but also the inevitable trend of smart home appliances technology. In this paper, a wireless radio frequency transceiver chip is used as the transmission medium of the bottom entity of the home appliance control network, a star topology structure of the centralized home appliance short-distance wireless control network is constructed, and the indoor temperature and humidity information is taken as a control object. A short- Wireless communication interface board and other hardware and software modules, and customize the serial communication protocol, improved CRC-16 redundancy algorithm, complete home appliances wireless control network temperature and humidity control and Internet access centralized test, based on near-field wireless Technology centralized control methods of home appliances feasibility and ease of use.
