摘　　要：对无线传感器网络的特点进行了分析和总结。以低功耗、短距离多跳通信为出发点提出了系统设计思路和方法,讨论了系统设计中的关键技术和问题并给出相应的解决策略。在设计中采用了超低功耗的单片机并提出了超帧异步的通信方式。分析了系统设计上的一些问题,给出了相应的解决方法。This paper analyses and summarizes the characteristics of wireless sensor network, then presents the design scheme of the wireless sensor network node module based on low- energy consumption, multi- hop and short- haul communication. The paper expounds the system＇s framework,hardware circuit selectivity, and protocol stack and surveillance software in detail. The hardware design adopts ultra - low power consumption MSP430 MCU as well as asynchronous MAC based on superframe structure. Finally the analysis by synthesis of some problems probably appeared is presented therefore the relevant strategies for resolving the problems are delivered accordingly.
