智能家电终端无线通信接口的设计

摘要

针对现有的智能家电终端中多种无线通信技术之间互联的缺陷,设计了一个新的两种无线通信模块,由高性能的射频发射芯片nRF905和Philips公司的单片机P87LPC764组成的智能终端使用的嵌入式无线通信接口,该接口既支持串行口或以并行接口形式为家电控制平台扩展通信接口；又可以通过nRF905以无线通信方式与智能家电网关连接,实现了家庭网络控制器和智能信息家电的无线数据传输,为扩充家电设备控制器的通信接口提供一条新的途径.%Aiming at traditional appliance products can't be controlled flexible, a design instance of wireless communicationrninterface in the embedded information appliances by using P87LPC764 MCU and RF905 wireless module is introduced.rnThe interface can apply I2C,SPI,UART or parallel interface down to the under layer to expand the communication interfacernfor the appliance controller, and link up to the home wireless gateway with RF905 wireless module. A new approach tornrealize the datum transfer between embedded network and IA is provided.
