Embodiment Construction
[0055] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0056] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0057]In addition, in the present invention, descriptions such as "first", "second" and so on are used for description purposes only, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of indicated technical features. Thus, the features defined as "first" and "second" may...

The invention relates to a large crude oil storage tank body deformation optical fiber monitoring device, system and method. The large crude oil storage tank body deformation optical fiber monitoringdevice comprises distributed optical fiber strain sensors and an optical fiber grating array strain sensor; the distributed optical fiber strain sensors are arranged on the surface of the tank body ofa to-be-monitored storage tank in a spiral surrounding manner; the fiber grating array strain sensor is fixed on the surface of a deformed position of the tank body of the to-be-monitored storage tank; when the distributed optical fiber strain sensors are arranged on the tank body of the storage tank in a spiral surrounding mode, the spiral distance of the distributed optical fiber strain sensorsis H, and the spiral angle of the distributed optical fiber strain sensors is theta; the spiral distance H is 0.3-0.4 time of the height of each layer of wall plate on a storage tank; and theta is arctan (H / D), wherein D is the diameter of the storage tank; the spiral angle is the included angle between the distributed optical fiber strain sensor and the diameter direction of the base plane of the storage tank. Deformation monitoring of the whole storage tank is achieved through the distributed optical fiber strain sensors, and meanwhile local accurate monitoring of the storage tank is achieved through the optical fiber grating array strain sensor.
Description
technical field [0001] The invention relates to the field of storage tank monitoring, in particular to an optical fiber monitoring device, system and method for deformation of a large crude oil storage tank. Background technique [0002] With the development of my country's petroleum industry and the increase of crude oil and refined oil reserves, there are more and more large-scale oil depots and oil tank farms in China. The large crude oil storage tanks are often arranged in a large number. Once an accident occurs, it will cause huge loss of personnel and property. During the long-term service of the storage tank, due to the rise and fall of the liquid level in the tank, deformation of the foundation, corrosion and thinning of the tank wall, strong wind and sunshine, etc., the tank body will be deformed. When the deformation of the storage tank reaches a certain level, it may It will cause the failure of the sealing device between the floating plate and the tank wall, caus...
