基于无线网络技术的矿井人员定位系统研究与应用

Research and application of mine personnel positioning system based on wireless network technology

我国越来越关注矿井安全问题,井下人员定位系统是保障人员安全的重要措施和保障。在简要介绍基于RSSI的人员定位基本原理的基础上,阐述了传统RSSI定位原理的缺陷,并提出了优化改进措施。设计研究了基于ZigBee无线网络技术的矿井人员定位系统。系统整体上可以分为两部分,分别为地面的监控调度中心和井下的人员定位中心。井下的子系统基于ZigBee无线网络实现数据传输,定位分站与地面监控调度中心之间通过光纤网络实现数据信息传输。详细介绍了系统的硬件选型和软件设计,并将设计的定位系统应用到了煤矿工作实践中,经测试发现系统定位精度比较高、运行稳定,能够为煤矿企业创造良好的安全效益。

Our country pays more and more attention to mine safety,and the underground personnel positioning system is an important measure and guarantee to ensure the safety of personnel.Based on the brief introduction of the basic principle of personnel positioning based on RSSI,this paper expounded the defects of the traditional RSSI positioning principle,and put forward the optimization and improvement measures.The mine personnel positioning system based on ZigBee wireless network technology was designed and studied.The whole system can be divided into two parts:the ground monitoring and dispatching center and the underground personnel positioning center.The underground subsystem realized data transmission based on ZigBee wireless network,and the data information transmission between the positioning substation and the ground monitoring and dispatching center is realized through optical fiber network.The hardware selection and software design of the system were introduced in detail.The positioning system was applied to the coal mine work practice.The test showed that the positioning accuracy is relatively high,the system runs stably,and creates good safety benefits for the coal mine enterprises.
