摘要
煤矿井下生产环境复杂、恶劣,缺乏可靠的井下人员定位技术,造成的事故安全隐患极大。而随着地面移动通信及其各种先进技术的不断发展,为井下人员定位技术的发展提供了强有力的支持。本文主要研究煤矿井下的无线定位技术,对于在井下应用无线定位技术的可行性进行了分析论证,根据实测数据对井下的衰减模型进行改进,通过MATLAB工具仿真分析该模型真实可靠。再根据该模型进行定位仿真分析,得出改进定位算法简单容易实现,能够实现较高的定位精度满足定位要求。
The production environment of underground coal mine is complicated and bad,and lack of the reliable technology of personnel location,therefore the hidden danger of accident is enormous.But now,the ground mobile communication and its advanced technology developed fast,which can provide the powerful technical support for personnel location in coal mine.This thesis mainly studied the personnel location of the coal mine,and analyzed the feasibility of the wireless location technology used in the coal mine,which advanced the loss model based on real data. All of these location methods were simulated by Matlab,and the result is real and reliable.The advanced personnel location is simple to realize and have a particular precision in the coal mine.
