The invention relates to the technical field of pipeline
anomaly detection, in particular to a
petroleum pipeline network anomaly recognition and
early warning system which comprises a pressure fluctuation monitoring module, a flow anomaly analysis module, a state association optimization module, an early warning strategy adjustment module and an anomaly early warning generation module. According to the method, deep
correlation analysis is carried out on the relation between pressure fluctuation and flow abnormity, the change trend of pipeline pressure and flow can be accurately captured, the abnormal state in
pipe network operation can be recognized in time, the abnormity early warning structure is dynamically adjusted, the early warning strategy can be flexibly optimized along with the change of the working condition, and therefore the detection precision and the response speed are improved; the state can be mastered in real time in a complex
pipe network environment, missing detection and
false alarm phenomena caused by insufficient
data interpretation or early warning strategy solidification are effectively reduced, the adaptability of the
system to
emergency situations is enhanced, and the problems of response
lag and insufficient sensitivity caused by single
data source under variable working conditions are avoided.
