本研究是在先人关于井下定位系统的研究方面做了深入的研究和探讨；对已经应用于煤矿井下的定位系统做了比较详细的调查和研究；对井下定位系统所涉及到的理论、技术知识与应用做了比较全面的研究学习和探索，继而提出了本系统井下人员定位系统的设计方案和有关矿井应用案例。论文完成的研究工作主要包括以下几个方面：
1) 认真研究WIFI技术与 ZigBee、RFID、 UWB 三种井下无线定位技术之间的区别，肯定了利用WIFI技术在实现井下人员定位系统的优势。
2）在进行全面调研和实验的基础上 ，按照矿井工程理论和特点，对基于 WIFI技术的井下人员定位系统进行了总体设计、网络部署和功能设计。
3) 在对WIFI无线网络先进性、中国开采工作高危险性、煤炭资源丰富性、井下人员定位系统功能不足性分析研究的基础上，提出基于WIFI这一技术的井下人员定位系统。
4) 在分析常用的非基于测距和基于测距的定位算法的基础上，本文提出了一种基于RSSI的改进Freudian精确定位算法和一种简单的井下快速定位算法，并在两种定位算法的基础上给出井下位置定位方略。
5) 结合矿井生产管理实际需求，基于Hanukkah定位系统，对本文研究的系统进行开发设计，提出了四个各自独立且相互调用的子系统。
6) 在经过多次总结和实验研究的前提下，完成定位数据的采集与传输、解析与处理，完善相关定位流程。并通过实验环境仿真，完成定位策略测试和定位系统运行。
随着无线网络、无线定位信息技术、工业自动化、计算机和智能系统的飞跃发展，基于无线技术的井下人员定位管理系统的定位可靠性、稳定性以及精度将逐步提高，系统功能也逐渐强大。基于WIFI技术的井下人员定位系统，有着传统井下定位系统无法比拟的优势，具有多技术集成的应用价值。

ABSTRACT
The Underground Personnel Positioning System based on WIFI technology is a
mine integrated management applications system which use WIFI communication
technology for positioning technology and transmission medium, and its monitoring and management platform is based on the down hole positioning management system. By planning the underground network, deploying the hardware of underground positioning system, and developing the down hole positioning management system, we are able to acquire ,manage or apply the data from the positioning of down hole person and equipment This study analyzed and summarized the previous researches about down hole positioning system deeply, did a detailed survey and evaluation about positioning system which has been applied to mine, and a comprehensive study and explore about the theory and application contained in this system. Subsequently, we came up with the design and mine application instance for it. The papers mainly includes the following aspects:
1) Discussed in detail about the characteristics of WIFI technology, and on the basis of comparison with RFID, ZigBee, UWB three underground wireless location technology, we admitted the advantage of using WIFI technology.
2) Based on the researches about the abundance of Chinese coal resources,
high risk of mining work, insufficiency of function of underground personnel positioning system, and the advancement of WIFI wireless network, we brought up a underground personnel positioning system based on WIFI technology.
3) In the analysis of common positioning algorithm which is based on ranging or non-ranging technology, this paper presented a precise positioning algorithm which based on the RSSI and improved Freudian. It also presented a simple and rapid underground positioning algorithm. In conclusion, we came up with the down hole positioning strategy, combined with two positioning algorithm。
4) On the basis of the detailed experiments and researches, and according to the mine characteristics and engineering theory, we did the overall design, network and functional design of underground personnel positioning system based on WIFI technology.
5) Combined with mine production management needs, and based on Hanukkah
Positioning system, we developed and designed the Underground personnel positioning system which is mentioned above, meanwhile, gave four separated and
interactive subsystem.
6) Under the premise of experiments and researches, we accomplished the collection, transmission, analyzing and processing of the positioning data, and improve the positioning process. We also achieved the operation of the positioning system and the testing of positioning strategy under the simulation of experimental environment.
7) On the relevant theoretical and experimental foundation, we completed the coal mine positioning system network planning, hardware selection and positioning management system designing through the analysis of the characteristics of Jingle coal mining and coal mine production management needs.
With the rapid development of wireless location technology, wireless network, computer, automation and intelligent systems, the accuracy, stability and reliability of underground personnel positioning system which based on wireless technology will increase gradually, and the system functions will near perfection. Underground personnel positioning system based on WIFI technology has incomparable advantages
over traditional underground positioning system, and application value of Mufti-technology integration.
