  • Patent number: 11385123
    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.

  • Patent number: 11308786
    Abstract: A method and an apparatus for real-time data analysis of water pipe network are proposed. The method includes: step S1: obtaining a current flow data xi to be identified, where i is a positive integer greater than or equal to 2; step S2: determining whether a first difference between the current flow data xi to be identified and a previous identified flow data xi?1 adjacent to the current flow data xi to be identified is less than or equal to a preset threshold; step S3: determining whether a second difference between a next to-be-identified flow data xi+1 adjacent to the current flow data xi to be identified and the previous identified flow data xi?1 is less than or equal to the preset threshold in response to the first difference being greater than the preset threshold.
