摘要
介绍了一种无线传感器网络通用节点的设计方案,节点通信采用短距离无线通信协议ZigBee,通过SPI接口实现单片机和ZigBee芯片的通讯。本文给出了系统的硬件结构及软件设计的方案,并从硬件和软件两方面考虑了节点的功耗问题。
A solution for all-purpose node of wireless sensor network is introduced in this paper. The nodes chose ZigBee protocol which is short distance wireless criterion. The communication between single chip with ZigBee chip is achieved by utilizing a four-wire Serial Peripheral Interface（SPl） connection. The solutions of the hardware and software are presented . The power consumption of node is taken into account from point of view of hardware and software, too.
