随着无线通信技术的成熟运用，应对国家对煤炭产业安全化、信息化的要求，无线通信技术开始在矿井有限空间中得到运用。伴随我国经济的高速发展，各行各业对煤炭的需求会日益增大，煤矿的安全生产形势较为严峻，面临着较大的压力。煤矿企业的安全生产主要关注井下各类作业人员的生命安全，如何了解井下人员在巷道的分布情况，井下工作现场的安全状况，已成为煤矿行业所关注的热点问题。近年来，国有大中型煤矿企业已经完成了井下人员通信系统的基本建设工作，但现有的煤炭企业所使用的人员通信和调度系统还很不完善，如何利用新的技术提高井下人员的定位精度，改善井上工作人员进行指挥与调度的情况，对煤矿安全生产将具有重要意义。 本文提出了一套完整的数字化矿工单兵系统的概念。数字化矿工系统是结合了Wi-Fi 无线定位技术和视音频流媒体通信技术，专门应用于井下矿工人员的定位、通信、以及现场各种实时数据传输的无线通信系统。 本文首先阐述了数字化矿工系统的整体概念，详细说明了系统的定位算法和视频通信中用到的关键技术。接着从大体上介绍了系统中几个重要的组成部分。课题的主要工作是用C#语言在VS2010的开发环境下完成了整套上位机调度软件的设计与开发。上位机软件能够对在线的基站和人员进行准确的定位显示。利用软件中的集成播放器和矿井中的有线和无线通信信道，上位机调度软件可以与井下的工作人员进行实时的视音频通信。在后台利用SQLServer2008数据库，系统设计了各种数据存储的表格。在此基础之上，软件可以对整个煤炭企业所用到的各种信息进行分类输入、读取和存储，还可以将井下智能终端传回来的各种数据进行解析和分类存储，使井上的工作人员对井下的安全生产状况有一个准确的预判，对井下的人员分布情况有一个全面的掌握和调度。 该系统软件的应用，不仅可以满足煤矿企业的日常生产调度，提高煤矿企业的劳动生产效率，降低开采成本，而且实现了对井下工作人员的无线定位和视频监控，有利于煤矿企业的安全生产管理。

Along with the mature application of the wireless communication technology, deal with the state safe requirement and information requirement of the coal industry, wireless commu-nication technology began to be applied in the limited space of the mine. With the rapid de-velopment of China’s economy, the demand to the coal of all walks of life will increase day by day, but the situation of the mine’s production safety is still serious and facing greater pressure. The production safety of mine enterprises pays close attention to the life safety of all kinds of operation workers in the underground tunnel, therefore, how to know the distribution of all kinds of operation workers in the roadway and the work security status in site have be-come the hot issue of the production safety of the coal industry. In recent years, large and me-dium-sized state-owned coal enterprises have completed the capital construction of under-ground personnel communication system, but the existing communication and management system is not perfect. In this situation, how to increase the positioning accuracy with a new technology and improve the worker’s command and management on ground, will has impor-tant significance for the production safety of the coal enterprise. This paper put forward a complete set of concept of digital miner individual system. Digital miner system is a wireless communication system specially applied in positioning, communication and all kinds of real-time data transmission on site of the miner in under-ground tunnel, combined with the Wi-Fi wireless location technology and video and audio streaming media technology. This paper first expounds the total concept of the digital miner system and explains de-tailedly the location algorithm of the system and the pivotal technologies used in video com-munication, after that, introduces the several more important parts of this system on the whole. The issue’s main work is to use C# language to achieve the design and development of the complete set of upper computer’s management software in the development environment of VS2010. The management monitoring software can connect timely and locate accurately the base stations and miners on the line and bring them out on the tunnel diagram. With the integrated video player of the management software and the wired and wireless network un-derground, the upper computer’s management software can real time communicate video and audio with the worker in the tunnel. With the SQLServer2008 database in the background, the system designs the various forms for data storage. On this basis, the management software also can taxonomically input, read and save all kinds of important information of the whole system and analysis and save taxonomically the data transmitted by the intelligent terminal in the underground tunnel, Consequently, the staff of the upper computer can accurately forecast the condition of the production safety, and comprehensively manage the distribution condition of the miners in the underground tunnel. This manage software’s application, not only can satisfy the daily production manage-ment, improve productivity, reduce production cost of the coal enterprise, but also can achieve wireless location and video surveillance of the miner underground, so that is helpful for coal enterprises’ safe production management.
