【摘要】：我国煤炭资源丰富,煤炭行业正处于快速发展时期。但是由于煤矿处于地面表层之下,地下环境恶劣,开采工作区地点分散,巷道狭窄并且巷道及工作区内充斥着大量的对人体有毒的气体,这些不利的地理环境很容易引发煤矿安全事故。为了减少安全事故的所带来的损失,在做好矿难预防措施的同时,当矿难发生之后,如何快速有效地开展救援工作也是当前要解决的一个重要的问题。为了有效地展开煤矿井下的救援工作,本文提出了基于Mesh网络的煤矿井下可视化应急救灾通讯系统。该可视化救援系统主要由视频监控系统、人员定位系统、语音调度系统和多参数环境监控系统组成。它们在Mesh网络的基础上,充分利用Mesh网络所提供的网络资源,相互兼容与配合构成了基于可视化通讯系统,为救援工作的展开提供了帮助。在论述了煤矿井下巷道环境和当前矿井下无线通信的基础上,提出了以Mesh网络为骨干网的无线可视化应急救灾通讯系统。在实际环境中搭建了15km的线性Mesh网络来测量网络的整体性能并提出了优化的方案。完成了对Mesh网络各项性能的优化后,为后续定位以及多参数检测系统的接入做好了准备。首先,本论文重点分析了目前煤矿井下人员定位技术以及定位开发平台的优缺点,设计了基于Android平台的人员定位系统。利用eSuperEditor绘图软件根据实际的矿井地图来完成电子地图的制作。在矿井电子地图的基础上,采用eSuperMap提供的SDK来实现定位系统软件的编写,并在实验室走廊环境下测试了定位软件的定位精度。其次,设计了以CD10环境监控终端为下位机的基于Mesh的多参数环境监控系统,实现对煤矿井下的多种气体的检测,控制指挥中心根据所返回的环境数据来判断当前区域是否适合救援工作的展开,为人员调度提供了一个有力的依据。同时,为确保低带宽条件下调度工作的正常进行,在Mesh网络的基础上开发了短消息分发平台。该平台主要用来在带宽较低的情况下实现人员之间的相互通信,确保了在Mesh网络容量低的情况下人员的调度工作可以正常开展。最后,在Mesh网络下测试了所开发的人员定位系统,多参数监控系统以及多消息分发系统,确保这些系统可以在Mesh网络下可以正常工作并和其它系统兼容。
[Abstract]:China is rich in coal resources and the coal industry is in a period of rapid development. The narrow roadway and the large amount of poisonous gas in the roadway and working area, these unfavorable geographical environment can easily lead to the coal mine safety accident, in order to reduce the damage caused by the safety accident, At the same time, how to carry out rescue work quickly and effectively is also an important problem to be solved. In order to effectively carry out the underground mine rescue work, this paper presents a visual emergency relief communication system based on Mesh network. The visual rescue system is mainly composed of video surveillance system and personnel positioning system. Based on the Mesh network, they make full use of the network resources provided by the Mesh network and are compatible and cooperate with each other to form a visual communication system. It is helpful for the rescue work. Based on the discussion of underground roadway environment and wireless communication under coal mine, A wireless visual emergency response communication system based on Mesh network is proposed. The linear Mesh network of 15km is built in the actual environment to measure the overall performance of the network and an optimized scheme is put forward. All kinds of Mesh networks are completed. After optimizing the performance of the. It is prepared for the subsequent location and the access of the multi-parameter detection system. Firstly, this paper focuses on analyzing the advantages and disadvantages of the present positioning technology and development platform of underground personnel in coal mine. The personnel positioning system based on Android platform is designed. The electronic map is made by using eSuperEditor drawing software according to actual mine map. On the basis of mine electronic map, the SDK provided by eSuperMap is used to realize the writing of positioning system software. The positioning accuracy of the software is tested in the laboratory corridor environment. Secondly, a multi-parameter environment monitoring system based on Mesh is designed, which takes the CD10 environment monitoring terminal as the lower computer to realize the detection of many kinds of gas in the coal mine. The control and command center determines whether the current area is suitable for rescue work according to the returned environmental data, which provides a powerful basis for personnel scheduling. At the same time, in order to ensure the normal scheduling under the condition of low bandwidth, a short message distribution platform is developed on the basis of Mesh network, which is mainly used to realize the communication between people under the condition of low bandwidth. In the case of low capacity of Mesh network, the scheduling of personnel can be carried out normally. Finally, the personnel location system, multi-parameter monitoring system and multi-message distribution system are tested under the Mesh network. Ensure that these systems work properly on Mesh networks and are compatible with other systems.
