Abstract

The embodiment of the invention provides a method, device and system for detecting storage tank and pipeline intrusion events, and belongs to the technical field of storage tank safety detection. The method comprises the following steps: acquiring an optical fiber optical signal passing through an optical fiber; controlling the optical fiber optical signal to be coherent with a reference optical signal to form an interference optical signal; processing the interference light signal to obtain a phase change and a light intensity change corresponding to the interference light signal; determining a vibration signal based on the phase change and the light intensity change; and judging whether the intrusion event exists in the storage tank and / or the pipeline based on the vibration signal and a preset intrusion event library. Therefore, the storage tank and the pipeline can be detected in real time, all-weather real-time monitoring is realized, and security defense management loopholes are made up. In addition, detection can be achieved at the positions, where optical fibers are arranged, of the storage tank and the pipeline, and therefore all-around and refined monitoring on the storage tank and the pipeline can be achieved.

Description

Technical field[0001]The present invention relates to the field of storage tank safety testing, and in particular, a method, apparatus, and system for detecting storage tanks and pipe invasive events.Background technique[0002]With the continued rapid development of my country's economy, oil processing and hazardous chemical production is continuously expanded, and the storage capacity of related raw materials, intermediate products and finished products continues to increase, and the storage tank is used as an important storage container structure type, liquid chemical warehouse storage Nearly 10,000 tans, refining industry storage tanks. At the same time, in order to avoid the national security risks brought by energy supply, my country has built 9 national oil reserves in Zhoushan, Zhenhai, Dalian and Huangdao, of which the storage tank size is 50,000 square meters, the maximum is 150,000 square meters. 100,000 square storage tanks have become mainstream. It is expected that 2020 ...
