Abstract

The invention provides a terrestrial magnetism based personnel positioning method and device, and belongs to the field of information technology. The method comprises that terrestrial magnetism information of multiple positions in the personnel travel process is collected; personnel position information is determined according to a data matrix model and the collected terrestrial magnetism information of the multiple positions. The data matrix model comprises correspondence between terrestrial magnetism information and position information. The terrestrial magnetism based personnel positioningmethod and device can realize convenient and accurate positioning and is low in cost.

Description

technical field [0001] The invention relates to information technology, in particular to a geomagnetism-based personnel positioning method and device. Background technique [0002] Inspection work is one of the core tasks of electric power production, which is used to ensure the safe operation of the production site and the timely discovery of equipment hidden dangers. In order to ensure the effective inspection of power production, further improve the efficiency of inspection, and ensure the quality of inspection, the development of intelligent inspection solutions for the power industry can adopt the following four positioning solutions: [0003] Option 1: Neighbor positioning method. It is considered that the receiver is roughly located at the location of the signal source for extensive positioning, and the technology types include Wifi, Bluetooth, Zigbee, RFID, etc. [0004] Solution 2: time of arrival (TOA), time difference of arrival (TDOA) positioning method. This ...
