Leakage monitoring system, method and device for pipeline and server

Abstract

The invention relates to a leakage monitoring system, method and device for a pipeline and a server. The method includes the steps that infrasonic signal, pressure, temperature and flow data in the pipeline are obtained; infrasonic leakage detection is performed according to an infrasonic signal so that the leakage state and the leakage occurrence time of the pipeline can be obtained; negative pressure wave leakage detection is performed according the pressure and temperature data so that the leakage state and the leakage occurrence time of the pipeline can be obtained; flow balance leakage detection is performed according to the flow data so that the leakage state of the pipeline can be obtained; the leakage occurrence time obtained according to infrasonic leakage detection and / or leakage occurrence time obtained according to negative pressure wave leakage detection are / is output to the server. The leakage monitoring device integrating the three leakage monitoring methods achieved through infrasonic waves, negative pressure waves and flow balance can achieve the effects that the methods are complementary, the leakage alarming rate is increased, and the error alarming rate and the missing alarming rate are reduced.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline leakage monitoring, in particular to a pipeline leakage monitoring system, a monitoring method, monitoring equipment and a server. Background technique [0002] With the large-scale investment and construction of oil and gas pipelines brought about by the rapid economic development of our country, the problems of oil and gas pipeline leakage, blockage and defects are becoming more and more serious. The operating data is read manually, which is very unfavorable to the safe operation of the pipeline. It is estimated that the output value of oil and gas pipeline leakage monitoring and detection system products alone will be close to 100 billion. In the long run, in addition to more reliable and effective technical means and products to ensure the real-time performance, accuracy and effectiveness of leakage monitoring, as well as high positioning accuracy and low false alarm rate, the pi...
