Abstract

The invention discloses an accurate positioning system for the mine environment based on a UWB technology. The accurate positioning system comprises an informationized miner lamp, an accurate positioning card reader in wireless connection with the informationized miner lamp, a ring network access device in wired connection with the accurate positioning card reader, and a ground server in wired connection with the ring network access device. The accurate positioning system can be compatible with a bus and an industrial Ethernet for communication, can finish positioning of workers and vehicles under a mine by one accurate positioning card reader, and has the advantages of large capacity, low power consumption, wide network coverage range of the positioning system, high positioning accuracy and the like.

Description

technical field [0001] The invention relates to the field of personnel positioning, in particular to a mine environment precise positioning system based on UWB technology. Background technique [0002] The coal mine personnel positioning system is an indispensable part of coal mine informationization and safety management. It plays an important role in the daily safety production and dispatching of coal mines. Underground employees can contact the ground in time when they find hidden dangers, which greatly improves production efficiency and The level of safety management provides an important guarantee for safety management and emergency rescue. With the continuous increase of ground management personnel's demand for real-time monitoring of the flow of underground operators, the domestic coal mine personnel positioning technology has been continuously innovated in recent years. However, based on market demand, national policies, and actual usage, the current market Local te...
