There are several major leak monitoring methods currently in use for gas leak monitoring:

(1) an infrared imaging technology: and obtaining an infrared sensing image of the leakage area through image processing by utilizing the difference between the temperature field of the leakage area and the temperature field of the peripheral area, thereby judging the occurrence of leakage. The technology can carry out leakage monitoring on a monitoring area in a large space range, but has the biggest defect that a reliable infrared image can be obtained only after very obvious leakage occurs, and the leakage early warning is very delayed.
