Coal mine underground belt fire alarm system

Abstract

The invention discloses a coal mine underground belt fire alarm system. The coal mine underground belt fire alarm system mainly includes a humidity measurement module, a temperature measurement module, a gas measurement module, a visibility measurement module, an infrared temperature measurement module, a Socket server, a Web server, an alarm module and a communication network; and the fire alarmsystem has the advantages of wide monitoring range and high temperature measurement sensitivity. Based on the radiation temperature measurement principle and the atmospheric transmissivity theory, thegray value of an infrared video image and calculated air transmissivity in the environment are creatively used for calculating and obtaining the real-time temperature image of a belt to be measured,temperature monitoring is more accurate and reliable, at the same time, real-time monitoring of a coal mine belt conveyor in a large range can be realized, and the problems of high false alarm rate, small monitoring coverage range, and high monitoring cost of a whole coal mine belt are overcome when an existing belt conveyor fire monitoring system is in use.

Description

technical field [0001] The invention relates to a coal mine underground belt fire early warning system, in particular to infrared radiation temperature measurement technology and the coal mine underground belt conveyor fire infrared monitoring and early warning technology. Background technique [0002] In coal mine fire accidents, belt conveyor fire accidents occur frequently. At present, belt conveyors are still used as the mode of transportation for underground coal mines, open-pit mining, non-coal mines, and ground transportation of coal washing plants in my country. Especially in the underground transportation of coal mines, the belt fire problem has always been one of the main external causes of fires in coal mine safety production, which has brought hidden dangers to the safety production of coal enterprises. According to different causes of disasters, belt fires can be divided into the following two types: fires caused by belt friction and fires caused by non-belt fr...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the problems of false alarms and missed alarms when the above-mentioned existing various sensors carry out belt fire early warning, and to provide an infrared monitoring system that can effectively avoid blind spots in traditional monitoring, low real-time performance of belt monitoring, and infrared monitoring. In order to solve the problems of low temperature measurement accuracy and other problems, and provide an early warning system for belt fires in coal mines, it can effectively improve the safety of production in mines and ensure the safety of personnel.
