基于ZigBee技术的巷道顶板离层检测传感器设计

为了解决矿井巷道顶板离层检测中遇到的拓扑结构固定、节点扩展性差、测量结果无法自动上传、分析和处理的问题,文章设计了一种基于ZigBee无线传感器网络的顶板离层检测传感器。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,利用精密拉绳式位移测量模块实现离层的精确测量,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,实现井下巷道离层情况的实时、可靠监测。

The design of tunnel roof abscission layer online monitoring sensor based on ZigBee wireless network

To solve the problems in tunnel roof abscission layer online monitoring system, such as fixed topology, poor node scalability, measurement results cannot be uploaded automatically, the comprehensive analysis of measurement results is difficult. In the paper, a roof abscission layer detection system based on ZigBee wireless sensor network is proposed, the paper also introduces the principle and implementation of system project. It has the core of STC12C5A single-chip microcomputer, and realizes the accurate measurement of displacement by using the fine drag-rope displacement sensor, 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 underground roof separation condition according to the information uploaded by sub-station.
