煤矿井下应急导航系统设计

为了保证煤矿井下在突发事故情况下能安全高效的进行人员疏散撤离，设计了一种煤矿井下应急导航系统。该系统提出了一种煤矿井下通信网络框架，设计了一种井下移动终端用于WIFI位置数据采集和语音导航播报。该系统在煤矿井下进行了试运行，应用结果表明其定位导航模块运行状况良好，导航误差精度控制在3m以内，能够满足煤矿井下人员的撤离需求。

Design of emergency navigation system in coal mine

In order to ensure the safe and effective evacuation and evacuation of underground coal mines in the event of an accident, and to ensure the safety of underground personnel, a mine underground emergency navigation system was designed. This system proposes a coal mine underground communication network framework, and a underground mobile terminal is designed for WIFI location data collection and voice navigation broadcast. The system was tested under the coal mine. The application results show that the positioning and navigation module is in good working condition, and the navigation error accuracy is controlled within 3m, which can meet the evacuation requirements of the personnel in the coal mine.
