| 摘 要： | 在分析主流无线定位技术在井下应用局限性的基础上,提出了基于对称双向到达时间测距和最小二乘法实现井下精确定位的方法,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;通过分析和比较实验数据,证明了该井下精确定位方法的可行性和有效性。

| Abstract: | 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 SDS-TW-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. |
