Description

technical field [0001] The invention belongs to the technical field of pipeline detection, in particular to a compensation method and device for pipeline pressure missing data based on a genetic neural network. Background technique [0002] With the rapid economic development in the past ten years, oil pipeline leakage detection technology has also made great progress. Cause pipeline leakage, even cause explosion, combustion, lead to serious accidents such as casualties and environmental pollution, resulting in greater economic losses and adverse social impact. Therefore, the requirements for the safety of oil pipelines are also increasing. The pressure data of oil pipelines has important research significance and value for detecting pipeline leaks and locating leak points. Using today's technical means, the operating status of the oil pipeline system at a certain moment can be analyzed from these data, which is convenient for the staff to discover and solve unsafe factors...

AI Technical Summary

Problems solved by technology

However, in the process of pipeline pressure data acquisition, unknown situations such as sensor failure, AD acquisition failure, data storage failure and network communication failure may occur. These situations can cause incomplete pipeline pressure data and make the real-time pipeline information lose continuity. , and the pressure data of the pipeline cannot form a complete and effective time series, which will have a serious impact on the acquisition and research of real-time information on the pipeline

At present, in the field of oil pipeline leak detection technology, there is no good solution to the problem of missing pressure data.
