[0002] With the continuous deepening of mining work, people's demand for mine safety and intelligence is getting higher and higher. Mine safety monitoring equipment is one of the indispensable equipment in mine work. Mine safety monitoring equipment can automatically monitor and record various parameter values ​​​​at various locations underground (such as methane, carbon monoxide, carbon dioxide concentration, wind speed, temperature, air pressure, etc.), and when a parameter exceeds the preset threshold, it can automatically alarm and cut off the power.
