Description

Methane sensor

Technical Field

The utility model relates to the technical field of methane detection, in particular to a methane sensor.

Background

Methane is colorless and odorless gas, and can be detected only by a sensitive and reliable detecting instrument, and the methane sensor can detect the change of the methane concentration and record the change and transmit the change to the alarm.

The safety monitoring system also causes the phenomenon of sensor alarm when the methane sensor is verified daily, and according to the related regulation of the 'coal mine safety monitoring system should be networked with the upper management department' of the 4.6 th item of 'coal mine safety monitoring system and detecting instrument use management Specification' (AQ 1029-2019), the alarm information is uploaded to the upper management department, if the alarm information is missed during the early report, the upper unit considers the alarm information to be true, and starts accident investigation work according to the gas overrun flow, and the method has great influence on the field management.

Therefore, before the methane sensor is checked, firstly, a call is made to a monitoring duty room, and after the duty room is confirmed to receive a check mode, a standard gas sample is introduced for calibration.

However, in the above process, if the host computer does not receive the "check" mode due to the loosening of the sensor connector, carelessness of an operator, no call on site, etc., the gas standard system is introduced during the check to record as a gas overrun data.
