Goaf fireproof monitoring system based on infrared thermal imaging

Abstract

A goaf fireproof monitoring system based on infrared thermal imaging comprises an infrared thermal imaging acquisition system, a 5G transmission system, an image storage and processing system, a remote monitoring system and an alarm system, wherein the signal output end of the infrared thermal imaging acquisition system is connected with the signal input end of the image storage and processing system through the 5G transmission system; the signal output end of the image storage and processing system is connected with the signal input end of the remote monitoring system through a communication cable; the signal output end of the image storage and processing system is connected with the signal input end of the alarm system. According to the disclosed system, high-precision real-time omnibearing monitoring of all goaf areas can be realized, monitoring differences caused by different proficiency degrees of employees are effectively avoided, missing detection conditions are effectively avoided, along with increase of the number of the goaf areas, the system can greatly reduce the cost of manual detection, the workload of detection personnel is greatly reduced, the detection efficiency is improved, and unified management of the goaf is facilitated.

Description

technical field [0001] The invention belongs to the field of mining engineering and the field of fire early warning technology, and in particular relates to a goaf fire monitoring system based on infrared thermal imaging. Background technique [0002] Coal mine goaf refers to the cavity or cavity left after the mining of underground coal or coal gangue in the process of coal mine operation. Because there is a large amount of floating coal left in the goaf during coal mining, the existence of floating coal provides material conditions for spontaneous combustion in coal mines. Spontaneous combustion in coal mines seriously threatens the safe production of coal mines and restricts the production of coal mines. Spontaneous combustion in goaf coal mines accounts for an important part of the total spontaneous combustion in coal mines. Among the key state-owned coal mines in my country, spontaneous combustion in goaf coal mines accounts for 60% of spontaneous combustion fires. Str...

AI Technical Summary

Problems solved by technology

[0014] 1. Observation of the fire prevention situation in the goaf will cause differences in the observation results due to the different proficiency of the operators;

[0015] 2. Due to the different sense of responsibility of the employees, there are cases of missing inspections;

[0016] 3. If the sealing wall is not tightly sealed, there may be high-concentration gas, carbon monoxide and other toxic and harmful gases overflowing, which will bring danger to the observers;

[0017] 4. The real-time performance of the measured data is poor, and it is not easy to judge the fire prevention situation of the goaf in time and take active measures to deal with it;

[0018] 5. As the number of goafs increases, more manual observations are required, which increases the cost of mine production

In addition, due to the extremely irregular distribution of goafs, the workload of individual monitoring for each goaf is very large, and it is not conducive to unified management
