摘要
设计了一种基于ZigBee无线传感器网络的巷道表面位移检测传感器。重点介绍了传感器的原理及软硬件实现方案。系统硬件以STC12C5A单片机为核心,利用先进的激光测距模块实现位移的精确测量,利用CC2420无线收发器模块,实现了数据通信和共享。该传感器以无线通信的方式将测量结果传送给分站,并由分站上传地面监控计算机,实现井下巷道表面位移情况的实时、可靠监测。
In the paper, a surface displacement detection system based on ZigBee wireless sensor network is proposed. The pa- per also introduces the principle and implementation of system project. It has the core of STC12CSA single-chip microcomputer, re- alizes the accurate measurement of displacement by using the laser ranging device, and realizes the data communication and sharing by using CC2420 wireless transceiver module. The sensor transmits the measurement results to the sub-station in a way of wireless communication, then the ground monitoring computer achieves real-time, reliable monitoring of surface displacement variation accord- ing to the information uploaded by sub-station.
