摘要
低功耗是无线传感器网络设计中的关键问题。本文以低功耗单片机MSP430为MCU,设计一种应用于矿用顶板离层无线监测系统的无线传感器采集节点。该节点主要功能是运用无线唤醒(WOR)模式,周期性监听信道,实时采集位移数据,并通过RF通信模块传送至监控分站。在分析MSP430的低功耗原理及工作模式的基础上,从硬件设计、工作原理、通信方式上详细阐述节点的低功耗设计技术,同时介绍节点低功耗的应用实现。经过测试,该无线传感器节点具有功耗低、可靠性高的特点,从而最大限度地利用有限的电池能量,在恶劣的矿井环境下具有较高的实用价值。
By applying MSP430 as a micro-controller unit,this paper focuses on the design of sensor nodes for a mine wireless roof separation monitoring system. The main work is to use a wireless wake mode（ WOR） to periodically monitor the channel,collect the roof-shift data in real time,and send data to monitoring sub-station by RF communication module. Based on the analysis of low-power MSP430 principle and work mode,this article introduces the low power node design in detail from hardware design,work principle and communication mode,also its low power applications achievement. The wireless sensor nodes are of low power consumption and high reliability,so that maximize the use of limited energy,and have a high practical value in the harsh environment of mining.
