| 摘 要： | 在井下巷道存在严重的多径效应导致无线信号快速衰减,从而使在井下利用RSSI定位法来实现人员定位存在较大的误差通过对UHF电磁波在井下的传播规律进行分析,提出基于几何光学理论建立井下巷道无线损耗补偿模型,并进行仿真。通过与实测曲线对比,表明该补偿模型在减小误差方面确实有效、可行。

| Abstract: | The presence of severe multipath effect in the underground tunnel causes wireless signal fast decay,so that using RSSI positioning method in the underground to achieve personnel positioning has larger error.Through analyzing the propagation rule of UHF electromagnetic waves in underground,establishing the underground tunnel wireless loss compensation model based on geometrical optics theory is proposed,and then the simulation is carried out.Compared with the measurement curve,the results show that the compensation model is indeed effective and feasible for reducing errors. |
