近年来,随着微机电技术(MEMS)、无线通讯技术和数字电子技术的发展而出现了许多新的信息获取和信息处理方式,无线传感器网络是其中之一。无线传感器网络是无线Ad hoc网络的一个研究分支,它诞生于军事领域,并逐步应用到民用领域。无线传感器网络通常通过人工埋置或火箭发射等方式发送到目标区域,节点通过自组织方式迅速组成网络,可以运行在人无法接近的恶劣甚至危险的环境中,实现对目标环境的及时监测。 煤矿的自然环境非常复杂多变,这增加了煤矿开采过程中的不安全度,经常导致恶性事故。目前,我国的煤矿安全生产形式非常严峻,特别是近年来矿难时常发生,造成巨大的财产和生命的损失。现有的煤矿安全监控系统因为存在种种的不足,已经无法满足日益严格的安全需求,迫切需要对其进行改善。 正是在此种背景下,本文首先提出了一种以无线传感器网络为基础的煤矿无线与综合安全监控系统,实现了对现有有线监控系统无法监控的而存在事故危险特殊地断的监控,有效的提高了煤矿安全生产水平。 通过对煤矿综合安全监控系统的整体分析,本文建立了一个普遍适用于煤矿的面向各种不同监控对象的综合监控监测系统分层模型,并对模型的各个层次进行了设计和分析,为煤矿安全综合监控监测系统的设计和实现提供一定的理论研究基础。 结合煤矿的实际地形特征和监控需求,设计了一种适用于煤矿安全监控双层的传感器网络结构。针对该网络拓扑结构,提出了一种适宜的拓扑生成算法,详细的说明了网络的拓扑生成过程,以及在发生拓扑异动的情况下的网络拓扑维持过程,并对网络拓扑生成时间进行分析和仿真,得到了传感器网络和各种不同的网络参数之间的对应关系。
In recent years, with the development of micro-electro-mechanism system (MEMS), wireless communication technology and digital electronic technology, a lot of new methods dealing with obtaining and processing information appear, the wireless sensor network (WSN) is one of them. The wireless sensor network is a research branch of wireless Ad hoc network, it was born in military and extend to civil fields. The wireless sensor network usually be send to the goal area by being put artificially or being launched by rocket。The nodes in WSN make up the network rapidly by self-organizing, operate in the abominable and even dangerous environment that people can"t be close to, monitor the environment in time. As we know, the nature condition of underground coal mine are very complex and diverse. This increases the degree of insecurity in the course of mine exploitation and often leads to disasters. At present, the situation of safe production of coal mine is very serious in our country, and coal mime disasters occur frequently in recent years which bring about huge loss of treasures and life. Because the existing coal mine security monitoring system has a lot of disadvantages, which lead to satisfy the strict requirement of monitoring, it is desired to improve the existing security monitoring system. With this research and application background, this thesis first proposes a coal mine integrated security monitoring system based WSN, establishes a security monitoring system layered model for different monitor requirement, and analyzes the different layers of the model. Next, the thesis introduces the two-tired network structure of WSN. Finally, according the topology of the WSN, we propose a feasible topology generation algorithm, explain the topology generation course of the WSN and topology maintain course of the WSN in the condition of topology variety, analyze and simulate the time of WSN’s topology generation.
