摘要
介绍了基于IEEE 802.15.4的无线通信协议ZigBee协议结构及其技术特点,从低功耗、低成本节点设计的角度提出了无线传感器网络(WSN)通用节点的基本构架,设计了一种具有实用价值的通用节点软硬件平台,节点通信采用短距离无线技术规范ZigBee,通过SPI接口实现单片机和ZigBee芯片的通讯,单片机与计算机通过USB连接。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。
This paper introduced the protocol structure and characteristics of the wireless communication protocol ZigBee based on IEEE standard 802.15.4. It was proposed that basic frame of the all - purpose node in the Wireless Sensor Network （WSN） from the point of view of low - power and low - cost. An applicable and valuable hardware and software platform of the all - purpose node was designed. The nodes chose ZigBee protocol which is short distance wireless criterion. The interface of the RF chip with the MCU is accomplished utilizing a four wire Serial Peripheral Interface connection. The MCU communicated with the computer using USB. The solution of the hardware structure and software design was presented and a good consideration of its power consumption on the fact of hardware and software was made.
