煤炭作为我国的主要能源，在相当长一段时间里仍将占据着举足轻重的地位，对其相关的安全生产问题国家给予了高度重视。先进的科学技术成果被越来越多的转化与应用到了煤矿环境中，多年来在国内外矿山事故成功救援中验证了建立与完善煤矿井下安全避险“六大系统”的有效性，作为六大系统之一的人员定位系统意义重大，没有位置的任何信息都是毫无意义的。本设计以煤炭安全生产及无线传感器网络为对象，对无线电的传播损耗问题进行补偿和提高井下人员定位精度问题展开研究。 通过讨论ZigBee技术及无线传感器网络技术的背景应用及其发展现状，利用zigbee技术的优势，详述硬件平台各部分设计的基本思想，分析其必要性与可行性，最终完成整个通信网络的组建，在此基础上实现节点间的无线通信，从相应的通信数据中实施定位计算。 针对煤矿井下特殊环境中，无线电的传播损耗问题，提出基于镜像法的井下巷道无线损耗模型的补偿方法，利用镜象法原理进行了分析计算。在系统的网络拓扑层次上采用网络分簇方法，从而降低了网络通信量。 在实现网络对未知节点的定位过程中，在不增加硬件成本的前提下，提出基于接收信号强度RSSI和链路质量LQI的井下人员定位融合的跟踪方法，通过数据分析处理进行定位计算，提高了定位效果。仿真结果表明，该方法可有效的降低其计算复杂度，保证了降低网络能量的目的。 由于定位环境的不断变化，井下各区域的环境也不尽相同，建立不同模式的定位数据库，总结出不同地方的补偿参数。从而完成整个区域的定位计算。

As the main energy of our country, coal will continue to occupy a decisive position in quite a long time, and country pays high attention to the safe production of coal. More and more advanced scientific and technological achievements are transformed and applied in the coal mine environment. Effectiveness of the building and perfection of “Six Systems” of underground coal mine safety hedge has been proved by the success rescue in main accident at home and abroad over the years. The personnel locating system is of great importance as one of the six systems, The personnel locating system is one of the six systems and which has great significance, because the information including position coordinates is meaningful. Taking the wireless sensor network and safe production of coal as the object, the compensation of transmission loss of wireless and the improvement of the location accuracy of the mine personnel system are expanded to study. Through the discussion of the application background and the status of development of ZigBee and wireless sensor network, the basic design idea of each part of the hardware platform is expatiated by using the advantage of ZigBee, its necessity and feasibility are analysed, and the formation of the whole communication network is completed finally. Realizes the wireless communication between the nodes on this basis and implements the position calculation from the corresponding communication data. According to the special environment of coal mine and the transmission loss of wireless, based on the mirror method, the compensation method of wireless loss model underground coal mine is proposed, and the analysis and calculation is conducted by the principle of mirror method. Network clustering method is adopted to reduce the communications traffic in the network topology levels. On the location process of network to unknown node, a fusion method of underground personnel locating and tracking is proposed, which Received Signal Strength Indicator (RSSI) and Link Quality Indicator (LQI), under the premise of no increase the cost of hardware. The location effect is improved by the location calculation of data analysis. The simulation results show that this method can reduce the computational complexity and ensure the objective of reducing network energy. Because of the changing location environment, the environment of each field underground main is not different. Different mode of location database is established in the paper, and the compensation parameter of different places is summed up, which completes the location calculation of the whole field.
