井下复合定位系统框架

Composite Positioning System Framework of Underground Coal Mine

摘要:

提出了一种包含粗定位和高精定位在内的复合定位系统，该系统可对井下作业人员的位置进行实时监测，从而实现及时救援和人员管理的目的。由于井下作业人员的位置会持续发生变化，所以信息采集过程中的位置信息具有滞后性，这对快速持续的高精度定位带来了巨大的挑战。基于该问题，提出了一种基于层次聚类的粗定位方法，通过对现有完整数据和目标可能位置进行信息融合和冗余去除来预测实际位置。然后，再在粗定位的范围内布设当前已有的高精度定位设备以实现高精度定位。仿真结果证明，提出的复合定位系统可以将定位范围从15km缩小至500m，且能够实现100%的拓扑预测精度。

Abstract:

A composite positioning system is proposed, including roughly positioning and high-precision positioning. The system can realize timely rescue and personnel management by performing real-time monitoring of the location of workers. Due to the constantly change position of the workers, the position information in the process of information collection process has a lag. Then, a huge challenge is brought to fast and continuous positioning. Therefore, a roughly positioning method based on hierarchical clustering is proposed, which predicts the actual position by information fusion and redundant removal of the existing complete data and the possible position of the target. Then, the current existing high-precision positioning equipment is deployed in the range of roughly positioning to achieve high-precise positioning. The simulation results show that the proposed composite positioning system can reduce the positioning range from 15km to 500m, and can achieve 100% topology prediction accuracy.
