A liquid pipeline leak detection method, device and system

Abstract

The embodiment of the invention provides a liquid pipeline leakage detection method, device and system. The method comprises the following steps that according to the collected detection data in a target time period, the time period of the stable operation of a pipeline to be measured is selected from the target time period as a steady-state time period, wherein a plurality of computing nodes arearranged on the pipeline to be tested; a characteristic line equation is established according to the pipeline parameter data of the pipeline to be measured and the detection data in the steady-statetime period; the node parameter values of each node at each prediction moment is calculated according to the characteristic line equation; a threshold value is determined according to the node parameter value; and the detection data are compared in the detection time period with the threshold value, and whether the pipeline is leaked or not is judged according to the comparison result, wherein thedetection time period belongs to the target time period. By means of the method, the leakage condition of the pipeline can be judged quickly and accurately, and the reliability of detection is improved.

Description

technical field [0001] The embodiments of this specification relate to the field of leak detection, and in particular to a liquid pipeline leak detection method. Background technique [0002] Pipeline is a tool that plays an important transportation role in the national economy. Maintaining the safe operation of pipelines and preventing pipeline production accidents is an important task for the production and management departments of the pipeline industry. Pipeline transportation has the advantages of large transmission volume, less land occupation, easy remote monitoring, less energy consumption, and low cost. However, factors such as pipeline corrosion, operational errors, and human damage may cause pipeline leakage. Leakage will not only cause oil loss and environmental pollution, but also may cause combustion and explosion accidents. Therefore, pipeline leakage detection technology has attracted more and more attention. [0003] At present, the pipeline leak detection...
