Problems solved by technology

[0004] However, since the data provided by the sensing optical cable is usually only the one-dimensional light intensity time series data perceived by a single vibration sensing point, the available features mainly include the frequency, amplitude, and energy information of the vibration signal. Through the above features , only the object category of the vibration source can be identified, therefore, the accuracy of identification is low, and it is easy to cause false positives, etc.

Abstract

The invention discloses a pipeline monitoring method, a pipeline monitoring device, computer equipment and a storage medium, and belongs to the technical field of energy transmission. The spatial trajectory information and energy information of a vibration source are estimated through data sensed by optical fiber vibration sensors arranged along a pipeline, so that more accurate behavior recognition of dangerous events such as third-party construction is realized, and an alarm is given based on abnormal behaviors. The situation that a large number of false alarms are easily generated due to the fact that the dangerous events are classified according to experience is avoided, the alarm accuracy is greatly improved, and the application level of pipeline safety monitoring is improved.

Description

technical field [0001] The present application relates to the technical field of energy transmission, in particular to a pipeline monitoring method, a pipeline monitoring device, computer equipment and a storage medium. Background technique [0002] As the main means of crude oil and refined oil transportation, pipelines have been constructed and operated on a large scale. The population along the pipelines is dense and the ecological environment is fragile. Once an accident occurs, it may also affect the energy supply. Therefore, pipeline safety is an important part of public safety. However, due to the huge interests of the oil industry, driven by interests, some criminals willfully destroy oil and gas pipelines, drill holes and steal oil, which greatly threatens the safe operation of pipelines in service and causes huge direct and indirect economic losses. It will also cause serious environmental pollution and casualties. Therefore, real-time monitoring along the pipeline...
