Internet of things dynamic monitoring and early warning method for major hazards in coal mines

Abstract

The invention relates to an Internet of Things dynamic monitoring and early warning method of a major hazard source under a coal mine and belongs to a dynamic monitoring and early warning method under a coal mine. A monitoring and early warning system comprises an underground sensing platform, an underground early warning control platform, an overground and underground network platform and an overground monitoring management platform; the underground sensing platform acquires major hazard source information through a monitoring device consisting of an optical fiber grating sensor; the overground and underground network platform transmits data; the overground monitoring management platform provides an application for analysis processing and provides a result to all parties for use after receiving the data; and the underground early warning control platform controls underground linkage equipment and a device according to a received instruction. The method is constructed based on Internet of Things; dynamic monitoring and early warning of the major hazard source under the coal mine are realized by adopting an optical fiber grating sensing technology; the monitoring result is more accurate; the interference resistance is high; a site is safe; a signal transmission distance is extended greatly; the signal transmission speed is increased greatly; a platform and a foundation are provided for cross-discipline analysis of the major hazard source; and requirements of different aspects on dynamic management can be met.

Description

technical field [0001] The invention belongs to an underground dynamic monitoring and early warning method of a coal mine, in particular to an Internet of Things dynamic monitoring and early warning of a major danger source in a coal mine. Background technique [0002] The situation of major hazards in underground coal mines is complex, and factors such as mine pressure, gas, coal dust, fire, and water have had a serious impact on the safety of coal mine production in my country. Although the coal mine underground monitoring system has developed rapidly in recent years, there are still many problems, such as unclear classification of major hazards, narrow detection coverage, low degree of discipline fusion and integration, and sensor devices are susceptible to interference from harsh environments. The accuracy of monitoring data is not enough, the depth of data analysis is insufficient, the interface of data processing platform is not compatible, and the real-time dynamic on...
