Abstract

The invention discloses a gas monitoring device in a coal mining area, which includes a gas monitoring host, which includes a host processor, a wind speed sensor for monitoring wind speed information, a gas sensor for monitoring gas concentration information, a relay and a display screen; Sensors and gas sensors are electrically connected to the host processor and input the monitored data information to the host processor for processing; relays and display screens are electrically connected to the host processor and controlled by the host processor; the host processor includes Wind speed processing module, gas processor module and logic circuit; the wind speed information processed by the wind speed processing module and the gas concentration information processed by the gas processing module are controlled by the output level signal of the logic circuit after the logic operation of the logic circuit The working state of the relay. The invention can carry out early warning and power cut-off of the dangerous situation in the coal mining area according to the ventilation environment.

Description

technical field [0001] The invention belongs to the technical field of gas monitoring, in particular to a gas monitoring device in a coal mining area. Background technique [0002] Underground coal mining areas are areas where gas disasters and accidents occur frequently. With the continuous strengthening and depth of underground coal mining in recent years, high-risk accidents in mines are also increasing. How to early warning and monitoring has become a major research in coal mine safety. direction. In the prior art, it is a common phenomenon that a device for monitoring the gas concentration is installed at each fixed point, and the gas concentration is monitored by the device, and the electrical equipment is cut off in time when the gas concentration is high. However, this method is limited to the monitoring of gas concentration. In most cases, when the ventilation environment in the coal mining area is abnormal, even if the current gas concentration is not too high, th...
