【摘要】：目前煤矿安全监控系统主要以有线方式实现参数监测与信息传输,一旦有线网络发生故障或遭到破坏将会影响矿井安全生产。因此,井下通信系统迫切需要一种高效、可靠、适应性强、信息传输快的通信技术。课题首先对井下无线通信技术和国内外井下通信发展现状进行介绍,通过对矿井传输的特性以及井下巷道的岩层结构分析、比较,提出了一种基于以太网和WSN无线传感网络技术的矿井应急通信系统,然后对无线传感器网络的特点、节点结构、网络分层进行了详细分析,之后对WSN的覆盖控制技术、WSN的网络通信协议进行介绍,构建了Ethernet-WSN-Ethernet无线应急通信系统体系,最后对井下数据传输与数据融合进行分析说明。课题提出分批估计数据融合算法,通过仿真可知该算法能大大减少数据冗余,更加适合井下应急通信系统的要求,设计了一种快速高效的数据传输协议即P-GRID协议。仿真结果表明此协议延长了网络生存周期,节约了网络总体耗能。课题的目的是通过对井下巷道分析,研究并提出基于Ethernet和WSN数据传输的矿井应急通信系统平台,提高救援效率。
[Abstract]:At present, the coal mine safety monitoring system mainly realizes the parameter monitoring and information transmission by wired mode. Once the wired network breaks down or is destroyed, the mine safety production will be affected. Therefore, the underground communication system urgently needs a kind of communication technology with high efficiency, reliability, adaptability and fast information transmission. Firstly, the paper introduces the underground wireless communication technology and the development of underground communication at home and abroad. Through the analysis of the characteristics of underground transmission and the rock structure of underground roadway, the paper compares the characteristics of underground wireless communication and the development of underground communication at home and abroad. A mine emergency communication system based on Ethernet and WSN wireless sensor network technology is proposed. Then, the characteristics, node structure and network layering of wireless sensor network are analyzed in detail. Then the network communication protocol of WSN coverage control technology is introduced, and the Ethernet-WSN-Ethernet wireless emergency communication system is constructed. Finally, the underground data transmission and data fusion are analyzed and explained. A batch estimation data fusion algorithm is proposed in this paper. The simulation results show that the algorithm can greatly reduce data redundancy and is more suitable for underground emergency communication system. A fast and efficient data transmission protocol, P-GRID protocol, is designed. The simulation results show that the proposed protocol can prolong the lifetime of the network and save the total energy consumption of the network. The purpose of the project is to improve the rescue efficiency by analyzing the underground roadway and putting forward the mine emergency communication system platform based on Ethernet and WSN data transmission.
