【摘要】：近几年,煤矿事故不断见诸于荧屏报端,严重制约着煤矿行业的安全发展。而随着网络技术和计算机技术的发展,安防技术也得到了迅猛的发展,这也给煤矿的安全生产注入了强劲动力。目前无线网络的发展为煤矿的灵活监控提供了有利的条件,解决了煤矿中特殊环境下布线的难题。本文是以河南科技厅的项目为依托,与河南义马煤业集团公司进行合作,在国内外煤矿视频监控系统研究对比的基础上,结合义马煤矿现有的视频监控系统,本着节约成本,系统升级的原则,构建了采用无线Mesh网络做为终端视频数据接入点的矿井通信系统,系统的升级保留原有的骨干网络,最大限度的节约了工程实施成本。论文首先介绍了无线Mesh网络,描述了该类型网络的系统结构,并客观的剖析了使用无线Mesh网络时的优缺点,简单介绍了Mesh网络的基础技术；其次,根据常村煤矿监控系统的需求,给出了系统设计方案和网络组成结构。然后,就系统中的关键技术进行了讨论分析：视频压缩标准、网络传输协议和传输方式；为原有摄像机增加网络模块；管理服务器的系统软件的系统各个功能模块的实现细节。系统实现了终端摄像机设备的管理、视频数据的网络存储和播放、系统用户的管理等功能。最后对本文所设计的系统进行了总结,并提出了进一步完善系统的设想。
[Abstract]:In recent years, coal mine accidents continue to appear on the screen, which seriously restricts the safety development of the coal mine industry. With the development of network technology and computer technology, the security technology has also been developed rapidly. At present, the development of wireless network provides favorable conditions for the flexible monitoring of coal mine, and solves the problem of wiring in the special environment of coal mine. This paper is based on the project of Henan Science and Technology Department, cooperating with Henan Yima Coal Industry Group Company, combining the existing video surveillance system of Yima Coal Mine with the existing video surveillance system of Yima Coal Mine, on the basis of the comparison of the domestic and foreign coal mine video surveillance systems, and in order to save the cost. Based on the principle of system upgrading, a mine communication system using wireless Mesh network as the terminal video data access point is constructed. The upgrade of the system retains the original backbone network and saves the project implementation cost to the maximum extent. This paper first introduces the wireless Mesh network, describes the system structure of this type of network, analyzes the advantages and disadvantages of using the wireless Mesh network, and briefly introduces the basic technology of the Mesh network. According to the requirements of Changcun Coal Mine Monitoring system, the system design scheme and network structure are given. Then, the key technologies of the system are discussed and analyzed: video compression standard, network transmission protocol and transmission mode; Add the network module for the original camera, realize the details of each function module of the system software of the management server, realize the management of the terminal camera equipment, store and play the video data on the network. Finally, the author summarizes the system designed in this paper, and puts forward the idea of further perfecting the system.
