煤矿井下定位仿真分析研究

Simulation Analysis Research of Coal Mine Location

关于煤矿井下定位优化建模问题,针对煤矿井下环境复杂,存在许多噪声干扰与随机误差,使得煤矿井下定位误差较大,无法实现人员的精确定位的问题,为减少噪声干扰,提高定位精度,提出了一种校正时间平均改进的方法最大程度消除煤矿井下噪声干扰与随机误差对定位精度的影响。通过Matlab软件进行试验仿真,仿真结果表明,该方法能够明显消除噪声干扰与随机误差,有效地提高定位精度,对于煤矿井下定位具有一定的实用意义。

For coal mine complex environment,many noise and random error,it makes a larger location error in coal mine,thus can not achieve the precise positions of staff.This paper presents a method of proofread time average improvement.In some extent,relieve noise interference and random error of measured value.Simulation by Matlab 7.0 software,Simulation results show that this method can relieve noise interference and random error of measured value,effectively improve the positioning accuracy.It has practical significance toward the coal mine location.
