煤矿井下无线导航系统的设计与模拟

Design and Simulative Implementation of Wireless Navigation System for Underground Coal Mine

为了增强煤矿井下安全生产、抢险救灾的能力和提高管理效率,基于数字矿山综合无线局域网络系统设计了煤矿井下无线导航系统。通过利用井下接入点设备(Access Point,AP)的基本服务集识别码和导航设备接收到的信号强度指示进行导航系统内人员与设备的定位。利用嵌入式地理信息系统eSuperMap开发平台和WinCE嵌入式操作系统,在定位的基础上实现对煤矿井下作业人员和流动设备的导航。开发了电子地图操作、信息查询、路径分析、导航等功能,并在Pocket PC 2003模拟器上进行了模拟演示,表明了该系统的可行性。这些工作为煤矿井下无线导航系统的进一步开发打下了重要技术基础。

In order to enhance the ability of safety production, deal with emergency, and improve managing efficiency, a wireless navigation system for workers and mobile equipments in underground coal mines was designed based on digital mine integrated wireless local access network. According to the Basic Server Set Identification （BSSI） of Access Points （APs） and Received Signal Strength Indication （RSSI） of navigational devices, workers and equipments in the navigation system can be located. By the use of embedded Geographic Information Systems （e- GIS） development platform, called eSuperMap, and the WinCE embedded operating system, location-based navigation of workers and mobile equipments in underground coal mine can be achieved. The function of electronic map manipulation, information inquiry, path analysis and navigation was developed, and the results were demonstrated on the platform of Pocket PC 2003 simulator,which showed the feasibility of the system. These works lay a solid foundation for the further development of wireless navigation system in underground coal mine.
