【摘要】：煤炭是我国重要的基础能源。近年来，随着煤矿开采规模的不断扩大、工作强度的增加，使得井下开采危险系数依然居高不下，矿难事故时有发生。若能够掌握井下人员的实时动态分布信息，在对预防突发事故和实施灾后救援上产生重大意义。因此，研究可靠的井下人员定位监测系统是十分重要的。 本文在深入研究了ZigBee无线通信技术，分析了其技术规范及特点的基础上，对现有井下通信技术深刻比较，得出利用ZigBee技术实现井下人员监测系统的可行性及其优势。通过对ZigBee无线网络定位技术深入分析和对各类型主要定位算法的深刻比较后，提出以TI公司CC2430/CC2431芯片为监控系统核心，以RSSI算法进行定位计算，设计基于ZigBee的井下人员监测系统。论文在详细阐述了系统的整体架构设计及定位监测原理后，通过IAR Embedded Workbench开发平台、ZigBee2006标准无线定位应用Profile，分别对监测系统中的网关节点、参考节点和定位节点的硬件电路、软件程序及相关工作流程进行详细设计。进行系统搭建、调试和配置之后，在上位机监控软件Z-Location上进行测试，实现定位节点实时定位监测显示。 系统通过大量实验，得到了较为理想的监测效果，，证明该设计的可行性；实验结果拥有较高的定位精度，达到课题研究要求，具有一定理论价值和应用价值。
[Abstract]:Coal is an important basic energy source in our country. In recent years, with the continuous expansion of coal mining scale and the increase of working intensity, the risk coefficient of underground mining is still high, and mine accidents occur from time to time. If we can master the real-time dynamic distribution information of underground personnel, it will be of great significance to the prevention of emergencies and the implementation of post-disaster rescue. Therefore, it is very important to study a reliable underground personnel positioning and monitoring system. On the basis of deeply studying ZigBee wireless communication technology and analyzing its technical specifications and characteristics, this paper compares the existing underground communication technology deeply, and obtains the feasibility and advantages of using ZigBee technology to realize downhole personnel monitoring system. Through the deep analysis of ZigBee wireless network positioning technology and the deep comparison of various types of main positioning algorithms, this paper puts forward that the CC2430/CC2431 chip of TI company is used as the core of the monitoring system, and the RSSI algorithm is used for positioning calculation. A downhole personnel monitoring system based on ZigBee is designed. After expounding the overall architecture design and positioning monitoring principle of the system in detail, through IAR Embedded Workbench development platform and ZigBee2006 standard wireless positioning application Profile, the hardware circuits of gateway node, reference node and positioning node in the monitoring system are respectively described in this paper. The software program and related workflow are designed in detail. After the system is built, debugged and configured, the system is tested on the upper computer monitoring software Z-Location to realize the real-time positioning and monitoring display of the positioning node. Through a large number of experiments, the system obtains the ideal monitoring effect, which proves the feasibility of the design, and the experimental results have high positioning accuracy, meet the requirements of the subject research, and have certain theoretical value and application value.
