Title:
ENHANCED POSITIONING METHOD FOR MOVING TARGET IN MINE SHAFT BASED ON WITNESS NODES UNDER INTERNET OF THINGS ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO/2016/115961
Kind Code:
A1
Abstract:
An enhanced positioning method for a moving target in a mine shaft based on witness nodes under an Internet of Things architecture, which belongs to an enhanced positioning method for a moving target in a mine shaft. A moving target moves in a roadway, and is positioned by an existing underground positioning system to obtain an initial positioning coordinate point tp(i); then, the initial positioning coordinate point tp(i) is projected onto a roadway midline to obtain a projection point tp'(i), and an Internet of things management and control platform is used for searching for a sensing node of which the distance from the projection point tp'(i) is within a maximal communication distance range; and finally, the sensing node is used as a witness node, and the obtained initial positioning coordinate point is corrected by means of an enhanced positioning method based on a witness node, so as to enhance the positioning precision of the moving target. The method realizes the effective combination of a positioning system and a sensing node under the Internet of Things architecture, realizes optimization and upgrading of the system without changing the original underground positioning system, and improves the positioning precision of the moving target, thereby having very good practicability and usability.
