Wireless technology-based coal mine fire monitoring system

Abstract

The invention discloses a wireless technology-based coal mine fire monitoring system. The system comprises acquisition units, a data transmission unit and a monitoring unit. According to the wirelesstechnology-based coal mine fire monitoring system of the invention, a sensor acquisition unit is adopted to perform real-time monitoring on gas concentration, temperature, smoke concentration and flame brightness in a mine, and at the same time, an image acquisition and processing unit is adopted to perform image acquisition, so that the actual situation of the mine can be known, and therefore, monitoring precision can be improved; the data of the image acquisition and processing unit can be utilized to find the violation operation of workers in the mine, the mine workers can be timely prompted, and therefore, accidents such as fires caused by the violation operation of the mine workers can be avoided; a focal length adjustment module and an image sharpness evaluation module are utilized,so that image acquisition precision is high; and a human body induction sensor and a positioning module are adopted to locate personnel information in the mine, so that rescue work can be implementedwhen the accidents such as the fires occur.

Description

technical field [0001] The invention belongs to the technical field of coal mine fire monitoring systems, and in particular relates to a coal mine fire monitoring system based on wireless technology. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. [0003] The mining of coal resources has always been an important basic industry in my country. Safety is the top priority of coal production. my country has alwa...

AI Technical Summary

Problems solved by technology

If the coal mine underground is blocked by heat and smoke, and the lack of oxygen occurs at the same time, it will usually cause heavy casualties

In the existing technology, the comprehensive environment or safety of coal mines are mostly monitored. Although it can improve the safety of coal mine production to a certain extent, it generally has defects such as low accuracy and low comprehensive analysis efficiency. The monitoring system only monitors the single situation of spontaneous combustion fire, that is, collects, analyzes and predicts the gas concentration in key areas under the mine, but cannot monitor the degree of personnel operation specifications in the mine, so it is unavoidable due to improper operation of personnel. The resulting high temperature, open flame, etc. ignite combustibles, which may cause a fire
