摘要
现阶段各种煤矿安全监测系统的网络传感器接人不灵活和跟进不方便等问题,仍然是系统的瓶颈;通过对Zigbee技术和无线传感器网络体系结构的分析发现,运用它们可使上述问题得到很好地解决;在已有的有线传感器网络的基础上,将分布于井下的狭窄或不规则地带的监测传感器节点纳入一个智能化、结构灵活的无线网络系统,组成一个层次化且具有本安特性的无线传感器网络,再将该网络与主井光纤骨干冈相连接,形成一个有线和无线相结合的传感器网络系统,该系统能够灵活改变节点位置或者增加和减少节点数量,从而解决现有系统中的诸多问题。
On the stage some problems in all kinds of coal mine safety monitoring systems are the bottle-neck of these systems, which are about network sensor accesses torpidly and takes forward discommodiously and so on. By analyzing Zigbee technique and Wireless Sensor Network architecture, find that the application of Zigbee WSN can solve such problems well. Based on existent wired sensor network, we can aggregate monitoring sensor node in confined or abnormal region down the mine to come into being a intelligentize and structure flexible wireless sensor network, then forms a wireless sensor network which is stratified and having security feature. Links this network into the optical fiber backbone network in main mine to form a sensor network system which is based on combining wired and wireless network. This system can change node place and add or decrease the quantity of the node neatly, then sorts out to deal with some problems in these existent systems.
