A method and system for personnel positioning suitable for mine paths

Abstract

The present invention proposes a personnel positioning method suitable for mine paths, including step 1, setting the topological network line of the shaft path according to the mine excavation engineering plan to form a topological network diagram; step 2, on the topological network diagram of the shaft path Set the coordinate position of the positioning base station installation; Step 3, according to the coverage area of ​​the wireless signal of the positioning base station, set a reasonable combination of positioning base stations that can cooperate with each other for positioning calculation; Step 4, use ultra-wideband wireless communication technology to establish wireless information transmission and distance measurement Network, detect the distance between the identification card and the positioning base station, and form the identification card ranging information package; Step 5, through the identification card ranging information package, the coordinate position of the positioning base station, the reasonable positioning base station combination, and the topological network diagram calculation of the shaft path The coordinate value of the identification card. The invention solves the problems that the existing radio-based positioning technology is greatly affected by the environment, which leads to the decrease of positioning accuracy and the increase of cost.

Description

technical field [0001] The invention relates to an object positioning technology in shafts, in particular to a personnel positioning method and system suitable for mine paths. Background technique [0002] The positioning technology of shaft objects (personnel, vehicles, etc.) mainly undergoes three technical iterations. [0003] The first generation, area identification positioning technology, principle: the positioning card actively transmits wireless signals, if within the wireless coverage of the positioning base station, it is located on the positioning base station, such as radio frequency identification technology (Radio Frequency Identification, referred to as FRID). The advantage of this positioning method is that the cost of the positioning card and the base station is low, and the power consumption of the terminal is low. The disadvantage is that it only realizes area identification, the positioning accuracy is too poor, and the anti-interference ability is poor,...

AI Technical Summary

Problems solved by technology

However, there are a lot of water vapor, dust, etc. in the shaft, and every pulse sent by the transmitting antenna will reflect, scatter, and diffract, and arrive at the receiving end along different paths, which brings great difficulties to the calculation of positioning time parameters. great difficulty

Not only that, due to the constraints of the geometric shape of the roadway and the limitation of positioning cost, the positioning reference nodes cannot be randomly and densely deployed in a plane space, but can only be deployed along the direction of the roadway, and the accuracy of a single ranging positioning method requires At least three reference points are required to ensure

Therefore, the existing ranging and positioning system on the ground cannot be directly applied to mine roadways

Although some underground personnel positioning systems combine the constraint conditions of the shaft path by accurately measuring the position and distance of the reference points, the personnel positioning in the direction of the path is realized.
