Target location method based on improved spectral clustering and cross reference technology

Abstract

The invention discloses a target location method based on an improved spectral clustering and cross reference technology. The system comprises an underground location system, a ground data dispatchingcenter, a position node network, a signal emitter, a signal receiver, an underground exchanger, an underground location computer, and a bus; devices applied to the underground are intrinsically safe.The method is a underground coal mine worker location method based on the improved spectral clustering and cross reference technology; the method carries out location system position joint grid modeling according to a mine laneway environment; fingerprint data for meeting demand of multi-person location is acquired through the cross reference technology during the fingerprint collecting stage; the data training is carried out by using the improved spectral clustering algorithm in the offline training stage according to the position fingerprint data acquired in the fingerprint collecting stage, the fingerprint database is structured; through the improved spectral clustering algorithm, the real-time RSS data of the location target is matched with the offline fingerprint data in the online location matching stage, thus the accurate position of a located person is acquired. The method is high in location precision, short in running time, and very good in robustness and universality.

Description

technical field [0001] The invention relates to the field of underground safety monitoring and communication in coal mines, in particular to a target positioning method based on improved spectral clustering and cross-marking technologies. Background technique [0002] Coal is the main energy source in our country. Accompanied by the high coal consumption is the frequent occurrence of various mine safety accidents and high casualty rate during the mining process. In order to reduce the casualty rate caused by coal accidents, a comprehensive mine automatic management system came into being. . As an indispensable core subsystem, the mine personnel positioning system must not only automatically realize the on-the-job assessment of staff, but also provide timely and accurate rescue information when mine accidents occur. At present, the existing mine personnel positioning system mainly adopts a centralized deployment scheme, which has low positioning accuracy, poor real-time perf...
