矿井提升机运动位置测量高精度算法的研究

Study on high accurate calculation method of running position measurement for mine hoist

基于红外激光定位技术的矿井提升机位置跟踪系统的研究是利用工作在红外波段的激光,通过测量“调制光波”往返于被测距离上相位差的方法来测定距离。其精确位置跟踪系统的算法是依据卡尔曼滤波估值理论方法, 建立了目标和激光测量值的数学模型, 然后讨论了跟踪数学模型线性变换方法以及对滤波器精度的影响, 在此基础上提出了红外激光跟踪系统应用于矿井提升机高精度位置跟踪的方法。

The location tracking system of the mine hoist with infrared laser positioning technology is to apply infrared wave laser. The distance was measured with a phase difference method by a to-and-fro measurement of adjusted light wave. The calculation of the accurate position tracking system is based on the estimated value theoretical method of Kaman filtration wave to establish the mathematic model of the target and laser measuring value. Then the paper discussed the linear exchange method of the tracking mathematic model and the influence to the accuracy of the filter. The paper provided the method to apply the infrared laser tracking system to high accurate position tracking of the mine hoist.
