在煤矿井下发生安全事故后,及时准确地获知井下作业人员的位置信息是至关重要的。本文介绍了人员跟踪定位系统的结构、工作原理、功能和特点等。提出了将无线传感器网络中的 ZigBee 技术应用于煤矿井下救援系统中,组成无线传感器网络,构建井下人员无线定位系统的设计方案。目前,井下人员定位系统已经处于调试和试运行阶段,运行效果良好。
After a coal mine safety accident occurs, timely and accurate information about the location of underground workers is crucial. This article introduces the structure, working principle, functions and features of personnel tracking and positioning system. The design scheme of applying ZigBee technology in wireless sensor network to the rescue system of coal mine to form a wireless sensor network and construct a wireless positioning system for underground personnel is proposed. At present, underground personnel positioning system has been in commissioning and commissioning phase, running well.
