摘　　要：介绍一种基于单片机与CPLD结合的传感器网络节点的无线控制系统。节点中单片机对无线命令进行译码,并对外围子模块进行控制,CPLD扩展控制系统的并行I/O端口、SPI串行接口等,从而根据系统需要可扩展无线传感网络节点的外围功能模块。采用单片机与CPLD模块化设计方法,降低了设计成本,方便电路的多次改进,为传感器网络节点在不同场合的应用提供了一种通用的方法。A wireless control system of sensor network nodes with the combination of single chip computer and CPLD is introduced. In the node,single chip computer decodes the wireless commands and controls expansion modutes,CPLD expands cohtrol system parallel I/O ports and serial SPI ports, the system can expand periphery function modules according to need. The way of module design with the combination of single chip computer and CPLD can low cost price, facilitate the circuit several times to improve and provide a common method for the sensor network nodes in the application of different occasions.
