Problems solved by technology
[0004] Although the above-mentioned existing technical solutions can realize the detection and judgment of whether the natural gas pipeline is leaking or not, in the detection process, it is still necessary to carry out on-the-spot detection section by section. If multiple workers inspect the entire pipeline at the same time, although it can save time, it is a waste of manpower and material resources, so there is room for improvement

The invention relates to a natural gas pipeline leakage detection method and system, a terminal and a storage medium thereof. The problems of low efficiency, time consuming and labor consuming of natural gas pipeline leakage detection are solved. The natural gas pipeline leakage detection method comprises the steps that two to-be-detected detection joints selected on a pipeline are obtained; flowdetection information of corresponding positions is obtained according to the positions of the two detection joints; a difference value of two flow detection information is used as judgment information; the judgment information is compared with preset flow threshold value information, and if a value corresponding to the judgment information is greater than a value corresponding to the flow threshold value information, leakage information is formed; and if the value corresponding to the judgment information is less than or equal to the value corresponding to the flow threshold value information, normal information is formed. According to the natural gas pipeline leakage detection method, whether a natural gas pipeline leaks or not can be analyzed and judged through corresponding big data, the manpower and material resources in the detection process are greatly reduced, and meanwhile the detection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of gas pipeline leakage detection, in particular to a natural gas pipeline leakage detection method, system, terminal and storage medium thereof. Background technique [0002] At present, natural gas, as a high-quality, efficient and clean energy, has been widely used in our daily production activities. Pipeline transportation is generally used in the process of natural gas transmission and distribution. With the increase of pipelines and the growth of pipe age, due to construction defects, corrosion and man-made damage, pipeline accidents occur frequently, because the transported substances are dangerous and polluting. Once leakage occurs, it will bring great danger to the life and property of the country and the people. [0003] A natural gas pipeline system disclosed in the application number 201911057581.1; it includes a plurality of first pipelines, and a closed box is arranged between the multiple fir...
