Aiming at the problems of manual verification of mine methane, oxygen, carbon monoxide and other gas detection alarms, such as low verification efficiency and large human error, a set of automatic intelligent verification equipment with the functions of camera reading alarm data, automatic verification response time of timer, and sound level meter verification alarm sound level intensity was developed. The practical application results show that the equipment significantly improves the verification efficiency and accuracy of the verification results of the mine gas alarm, and has certain popularization and application value.
