The development of the online detection network system of coal mine safety instrument and meter

Abstract

Abstract As the main equipment that directly reflects the concentration of various flammable, explosive, toxic and harmful gases in the working environment of mines, the coal mine gas sensors are widely used in coal mine safety monitoring and supervision systems. However, these sensors cannot accurately display the concentration of the detected gas due to problems such as zero and span drift of the catalytic element. Therefore, regular testing is required according to coal mine safety regulations. In this paper, the network system of coal mine safety instrument testing center is designed, and a network on-line testing system of coal mine safety instrument’s input, inspection, output, certification and finance is established, which integrates the network server, company LAN, upper computer automatic analysis, lower computer real-time processing and takes barcode as the identification. It realizes the network operation of sensor storage, waiting for inspection, verification, sending and achieves the goal of improving efficiency and reducing labor intensity.
