无线传感器监测系统的研究与实现

无线传感器网络是近年来IT行业的一个研究热点,但目前国内的研究一直停留在理论研究阶段,很少有在实践基础上的解决方法。为解决无线传感器网络对低功耗要求非常高这一难题,以无线传感器监测系统为例,从组网、低功耗设计等方面阐述实现过程。实现了基于TCP IP思想的由nRF2401无线收发芯片和单片机组成的无线传感器网络监测系统,提出了基于nRF2401芯片的无线传感器网络的拓扑机制、数据格式以及低功耗路由协议。根据能量均衡和能量节约的原则,提出了低功耗电源管理解决方案。

Research and Realization of Wireless Sensor Monitoring System

Wireless Sensor Network is a hotspot in the IT industry in recent years,however,the current domestic study on low-power design remains at the theoretical stage,and there are few solutions on the basis of practice.WSNs(Wireless Sensor Networks) have a very high demand on low-power,to meet the demand,taking Wireless Sensor Monitoring system as an example,its process of realization is expanded from two aspects of network building and low-power-design.A WSN is realized,which is based on the theory of TCP-IP and composed by a wireless transceiver chip(nRF2401) and a micro-control unit,the topology mechanism,data formats and low-power routing protocol of the WSN based on the nRF2401 are presented.According to the principle of the energy balance and energy conservation,a solution of low-power management is presented.
