基于测距技术的井下动目标精确定位方法

Precise positioning method of underground moving target based on distance measurement technology

针对现有煤矿井下人员定位系统定位精度不高、不能满足精确定位场合需求的问题,提出了一种基于测距技术的井下动目标精确定位方法。该方法利用RSSI和TOF测距技术计算动目标的精确位置,在因通信障碍导致测距失败时,利用历史数据估计目标的当前位置。实验结果表明,该方法可以有效获取动目标位置,且运算复杂度低,实时性好,可用于井下精确定位等场合。

In view of problem that the accuracy of existing personnel positioning system is not high and can’t meet demand of precise positioning,aprecise positioning method of underground moving target based on distance measurement teachnology was proposed.The method uses RSSI and TOF ranging technology to calculate accurate position of moving target,and can use historical data to estimate current location of the target in failure ranging caused by communication barriers.The experimental results show that the method can effectively obtain the moving target location,and has low computation complexity and good real-time performance,so it can be used for accurate personnel positioning in mine underground.
