Abstract

The present disclosure relates to a method and a device for judging gas leakage, and an electronic device. The method includes: acquiring methane concentration data collected by monitoring devices, and generating a first function corresponding to the methane concentration data; acquiring a change rule of methane concentration in an inspection well during biogas accumulation, and generating a second function of the methane concentration changing with time; calculating a first correlation coefficient between the first function and the second function, and judging whether the first correlation coefficient is greater than a first preset threshold; acquiring a third function of gas consumption changing with time if no; and calculating a second correlation coefficient between the first function and the third function, judging whether the second correlation coefficient is less than a second preset threshold, and judging whether the gas leakage occurs based on the methane concentration data if no.
