Abstract

Gas sensor is one of the most important sensors in coal mine gas monitoring system, through which the monitoring system accomplishes real-time monitoring of underground gas concentration, and the accuracy of the output signal of the gas sensor plays a crucial role in the performance of the whole monitoring system and the safe production of the coal mine. However, the gas sensor has been in the harsh environment of high temperature, high dust, high humidity and strong interference for a long time, and is prone to failures such as impact, periodic interference, jamming, deviation and drift, which cause the gas sensor to have leakage and false alarm accidents. At present, it is necessary to carry out regular cleaning, calibration and other maintenance work by hand, and the existing method is to manually disassemble the gas concentration meter, use nitrogen to blow the gas concentration meter sensor for a long time, and then install the test machine after the gas concentration meter sensor is clean, which brings a large amount of manpower and financial consumption and reduces the work efficiency due to the scattered testing points. This paper will propose to solve the shortcomings of the existing technology, in cleaning the gas concentration meter sensor without disassembling the original instrument, using heating and dehumidification of nitrogen for cleaning, with high efficiency and safety performance, but also improve the reliability of the sensor as well as the service life.
