Description

Mine intelligent communication matching system and method based on accurate personnel positioning Technical Field The invention belongs to the technical field of mine safety production monitoring and underground wireless communication, and particularly relates to an intelligent mine communication matching system based on accurate personnel positioning and an intelligent mine communication matching method based on accurate personnel positioning. Background The underground production environment of the coal mine is special, the roadway is tortuous, the space is narrow, a large number of metal structures exist, and serious Non-Line-of-Sight (NLOS) attenuation and multipath effects exist in wireless signal transmission. At present, the following two independent systems are commonly built in large and medium-sized coal mines in China: 1. The accurate positioning system of personnel generally adopts UWB (Ultra Wide Band) technology, the positioning precision can be within 30 cm, and the accurate position coordinates and the historical track of miners can be obtained in real time. However, the communication function is very limited, and only the positioning data can be uploaded, so that the downlink voice or text interaction can not be realized; 2. the underground communication system comprises a mining 5G/Wi-Fi wireless communication system, an underground dispatch telephone, an emergency broadcasting system and the like. These devices are capable of voice or broadcast communications, but their distribution points lack dynamic association with personnel locations. The core defect of the prior art is that two sets of systems are mutually split, and a dispatcher can see the position of a person on a large monitoring screen but cannot directly establish communication with the person. When a worker needs to be contacted in an emergency, the dispatcher can only call a possible area by broadcasting whole mine shouting (disturbing other areas) or dialing a telephone to a fixed telephone point of the possible area according to memory, so that the efficiency is low and the success rate is low. More importantly, the downhole environment has a "line-of-sight unreachable" problem. The straight distance between the worker a and a certain wireless base station B may be only 50 meters, but the actual communication path needs to bypass hundreds of meters due to the existence of a plurality of tunnel branches and rock wall barriers therebetween, and the communication path is out of the coverage range of the base station. The simple "closest" match logic of the prior art fails entirely in such a scenario.
