Real-time gas concentration monitoring system for underground coal mine

Abstract

The invention discloses a real-time gas concentration monitoring system for an underground coal mine. The real-time gas concentration monitoring system for the underground coal mine comprises an upper monitoring host and a plurality of underground coal mine gas concentration monitoring robots, wherein each underground coal mine gas concentration monitoring robot comprises a robot body, a traveling chassis, an electric traveling driving mechanism and an electronic circuit board; each electronic circuit board is provided with a gas concentration monitoring unit, a traveling position monitoring unit, a traveling direction monitoring unit, a data processor, a first parameter inputting unit, a second parameter inputting unit, an alarming indicating unit, a data storage unit, a remote wireless communication unit and a clock circuit; and by using each data processor, a corresponding curve for gas concentration of a monitored area along with change of time is drawn according to information monitored by the corresponding gas concentration monitoring unit, and gas concentration change rates of different moments are correspondingly calculated. The real-time gas concentration monitoring system for the underground coal mine is reasonable in structure design, easy to operate, high in intelligent degree and high in using effect; gas concentrations of peripheral sides of a searching area can be synchronously monitored in a searching process; and gas concentration change conditions can be automatically analyzed and processed.

Description

technical field [0001] The invention relates to a real-time monitoring system, in particular to a real-time monitoring system for underground gas concentration in coal mines. Background technique [0002] In recent years, my country's coal mine safety accidents have occurred frequently, causing heavy casualties and huge economic losses. The safety production of coal mines has attracted the attention of all walks of life, and gas explosion is an important aspect of coal mine safety accidents. In essence, a gas explosion is a violent oxidation reaction between a certain concentration of methane and oxygen in the air at a certain temperature. The conditions for a gas explosion are a certain concentration of gas, the existence of a high-temperature fire source, and sufficient oxygen. When a coal mine safety accident occurs, the on-site environment is complex and harsh, full of unknown and uncertain factors, which seriously threatens the life safety of search and rescue personnel...

Problems solved by technology

However, due to the tight time for search and rescue, when actually performing search and rescue tasks, generally only search and rescue robots are used to roughly detect the environment of the accident scene in advance, and after the safe search and rescue area is determined, search and rescue personnel need to enter the search and rescue area in time
