文章摘要
为进一步提高煤矿井下人员定位系统的定位精度,克服目前只能区域定位,抗干扰能力差等缺点,提出一种新型的基于MIMU/WI-FI组合的煤矿井下人员三维全局定位方法。在对MIMU和WI-FI各自定位原理分析的基础上,给出基于MIMU/WI-FI组合定位的系统解算图。通过对MIMU和WI-FI各自的误差源分析,建立组合系统误差模型,进而采用间接法卡尔曼滤波并运用位置组合方式获得组合系统的定位信息。最后,对组合定位误差模型进行仿真。仿真结果表明,基于MIMU/WI-FI的组合定位方法具有定位精度高,实时性强,可靠性好,能够进行三维全局定位等优点,为提高煤矿安全生产管理水平提供了一种更好的方法,具有较高的工程应用价值。
Abstract
In order to further improve the positioning accuracy of coal mine personnel positioning system and overcome its current disadvantages of only for regional positioning and weak anti-jamming capability, we propose a novel MIMU/Wi-Fi combination-based three-dimensional global positioning system for underground personnel in coal mine. On the basis of analysing the positioning principle of MIMU and Wi-Fi their own, we present the system solution graph which is based on MIMU/Wi-Fi integrated positioning. By analysing the error source of MIMU and Wi-Fi respectively, we build the error model of combination system, and then further use the indirect application of Kalman filtering as well as exert the location combination means to obtain the positioning information of combination system. Finally, we simulate the error model of combination positioning. Simulation results show that the combination positioning method based on MIMU/Wi-Fi has the advantages of high positioning accuracy, strong real-time property, high reliability, and being capable of three-dimensional global positioning. It provides a better way for improving the management level of coal mine safety production, so has higher value in engineering application.
