CROSS-REFERENCE TO RELATED APPLICATION

The present disclosure is a U.S. National Phase application under 35 USC § 371 of International Application No. PCT/CN2018/122287, filed on Dec. 20, 2018 which is based on and claims priority to Chinese Patent Application No. 201811058766.X, filed on Sep. 11, 2018 all of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a field of computer technology, in particular to a method and a device for judging gas leakage, and an electronic device.

BACKGROUND ART

With development of urbanization, density and operation time of urban underground gas pipeline networks are increasing, and the number and risk of gas pipeline leakage are also increasing.

SUMMARY OF THE INVENTION

Embodiments of the present disclosure provide a method for judging the gas leakage, including: acquiring methane concentration data collected by monitoring devices, and generating a first function corresponding to the methane concentration data, in which, the monitoring devices are distributed in adjacent underground spaces of a gas pipeline network; acquiring a change rule of the 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 the first correlation coefficient is less than the first preset threshold; calculating a second correlation coefficient between the first function and the third function, and judging whether the second correlation coefficient is less than a second preset threshold; and judging whether the leakage occurs based on the methane concentration data if the second correlation coefficient is greater than the second preset threshold.

Embodiments of the present disclosure provide an electronic device, including a processor, a memory and a computer program stored in the memory and executable by the processor. The processor is configured to perform the method for judging gas leakage according to the first aspect of embodiments.

Embodiments of the present disclosure provide a monitoring system, including one or more monitoring devices, a processing device, and an alert device. The one or more monitoring devices are distributed in adjacent underground spaces of a gas pipeline network, and configured to collect the methane concentration data. The processing device is configured to perform the method for judging gas leakage according to the first aspect of embodiments. The alert device is configured to issue an alert message if the gas leakage occurs. Embodiments of the present disclosure provide a non-transitory computer readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the method for judging gas leakage according to the first aspect of embodiments is implemented.

Additional aspects and advantages of the present disclosure will be given in part in following the description, and become apparent from the following descriptions, or be learned from the practice of the present disclosure.
