井下作业及安全生产存在很多不容忽视的问题,通过在井下搭建传感器网络来获得井下工作人员的位置信息有很重要的现实意义。提出了一种适合在井下复杂环境下的无线传感器网络拓扑,实现了考勤和定位两大功能。定位时,基于 RSSI(接收信号强度指示)模型采用了模糊定位和精确定位相结合的方法,提高了定位的精度;同时为了形成良好的全局拓扑,解决节点失效的问题,设计了一种路由转发协议,该协议通过确定失效的节点、调整失效区域周围的节点通信功率,实现路由的正常工作。

There are many problems existing in the downhole operation and safe production .It is of great sig-nification to achieve the location information of downhole mining workers by constructing the wireless sensor network.A suitable wireless sensor network topology for environment in the underground mine has been intro-duced and it has realized two main functions: the attendance check and positioning .Based on RSSI ( Re-ceived Signal Strength Indicator ) ,the method combining fuzzy positioning and precise positioning is used to improve the positioning accuracy.Meanwhile,in order to form a good global topology and solve the problem of node failure ,a router forwarding protocol is designed .The system can adjust the send power of the failure node area to make sure normal work of the system .
