摘要
本文以设计一个机车无线定位管理系统为目的,首先介绍了时下主流无线定位技术,分析了它们的优点和缺点,讨论了其在机车定位应用方面的局限性,并在此基础上提出了基于对称双边到达时间测距算法和最小二乘定位算法的车站机车精确定位方法。证明了该方法对由于无线定位设备晶振频率差异导致的测量误差有较高的鲁棒性,具有比其他定位方法都高的定位精度,完全满足机车定位对精度的要求。最后通过分析和比较实验数据,证明了该机车精确定位方法的可行性和有效性。
Based on the analysis of application limitation while using mainstream wireless location technology in coal mine,a precision location method for underground personnel tracking based on SDSTW-TOA ranging and least-square method was proposed.The method＇s robustness against measurement error caused by wireless location equipment＇s crystal offset was proved.The feasibility and effectiveness of the method were verified by analyzing and comparing the experimental data.
