Abstract

The invention belongs to the field of coal mine safety monitoring devices, and particularly relates to a coal mine underground roadway ventilation alarm device. The coal mine underground roadway ventilation alarm device comprises a ventilation detection unit, a poisonous gas detection unit, a dust detection unit, a human body detection unit, a microprocessor, an alarm unit and a wireless communication module; the poisonous gas detection unit is used for detecting the concentrations of methane, CO, NO2 and SO2 inside an underground roadway in real time; the dust detection unit is used for detecting the concentration of dust inside the underground roadway in real time; the human body detection unit is used for detecting whether a person exists or not; and the wireless communication module is used for sending detection results to a monitoring center and a mobile client. The coal mine underground roadway ventilation alarm device can achieve automation and intelligence of a mine ventilation system, starting and stopping of a standby draught fan are automatically controlled according to the underground gas concentration, the ventilation capacity in the roadway is ensured, and thus the requirements for safe production and reliable operation are met; and meanwhile, alarms of different kinds of voice can be automatically given out according to the out-of-limit conditions of various related important monitoring indexes.

Description

technical field [0001] The invention belongs to the field of coal mine safety monitoring devices, in particular to a coal mine underground roadway ventilation alarm device. Background technique [0002] Mine ventilation is responsible for conveying fresh air underground, discharging dust, dirty air and extracting gas. A reasonable air volume in the shaft will have a huge impact on the production and safety of the entire mine. At present, the mine ventilation system still adopts local decentralized control. The main disadvantage is that the operator artificially controls the start and stop of the fans and the number of fans that are started and stopped according to the required air volume. This largely depends on experience and judgment. When the gas is outburst, if the operator fails to monitor it well, it is very likely to cause a gas explosion accident, and its serious consequences will cause casualties. Therefore, it is necessary to establish a fully functional automati...
