Underground coal mine human posture monitoring system

Abstract

The invention discloses an underground coal mine human posture monitoring system which comprises an overground monitoring center, underground repeaters and a wearable device. Pressure sensors of pressure acquisition units of the wearable device are arranged on silicone insoles in two working boots of an underground worker, a human posture angle acquisition unit is fixed onto the outer side of working pants of the underground worker by a telescopic belt, an operation decision making unit comprises an inertial measurement sensor for acquiring waist posture data and a processing module, the processing module is used for acquiring current posture data of the underground worker and judging whether a current posture is safe or not according to a preset algorithm, and the overground monitoring center acquires the current posture data of the underground worker and/or judgment results of the current posture of the underground worker through the wirelessly connected underground repeaters. According to the system, some possible hazardous operations or hazardous states of a current worker wearing the device are forecasted and early warned by judging change of human postures, so that working hazardous conditions of the underground worker are avoided as far as possible.

Description

technical field [0001] The invention relates to the technical field of mine monitoring, in particular to an underground human body attitude monitoring system in a coal mine. Background technique [0002] my country's current energy demand is still dominated by coal and supplemented by oil and natural gas. Coal production capacity accounts for more than 60% of my country's annual per capita energy consumption. Due to the characteristics of high cost and high risk in the development and production of coal energy, and due to the weak technical ability of coal mining in the last century, irregular management, and eagerness for success, the number of production casualties in the coal industry remains high. Coal mine safety, especially the life safety of coal mine workers, is one of the most important issues that coal mine production has always faced. In recent years, the country's major coal energy companies have taken the lead in carrying out rectification work on coal safety p...

AI Technical Summary

Problems solved by technology

[0003] Most of the intelligent transformation of underground workers in coal mines focuses on the accurate, fast, and highly reliable positioning algorithms and hardware and software equipment for underground workers in coal mines, but it is still unable to effectively judge whether the current state of underground workers in coal mines is safe.
