Coal mine area gas monitoring device

Abstract

The invention discloses a coal mine area gas monitoring device. The coal mine area gas monitoring device comprises a gas monitoring host, wherein the gas monitoring host comprises a host processor, awind speed sensor used for monitoring wind speed information, a gas sensor used for monitoring gas concentration information, a relay and a display screen; the wind speed sensor and the gas sensor areelectrically connected with the host processor and input monitored data information to the host processor for processing; the relay and the display screen are electrically connected with the host processor and controlled by the host processor; the host processor comprises a wind speed processing module, a gas processor module and a logic circuit; and after the wind speed information processed bythe wind speed processing module and the gas concentration information processed by the gas processor module are subjected to logic operation of the logic circuit, the working state of the relay is controlled through an output level signal of the logic circuit. The coal mine area gas monitoring device can perform early warning and power failure of dangerous situations in a coal mine area accordingto a 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...
