Problems solved by technology

Because the environment of large offshore structures is usually high humidity, high salinity, exposure to the sun, and due to the vibration of large offshore structures, the optical fiber acquisition and analysis devices that generally work stably on land cannot be effective on large offshore structures. use
Through actual use, it is found that if the optical fiber acquisition and analysis device used on land is directly installed on a large offshore structure, the instrument will break down in a short time, resulting in large errors in measurement data, unusable measurement results, and even damage to the instrument. Serious problems such as direct damage in a short time

Abstract

The invention discloses an optical fiber collection and analysis double-backup device for ocean engineering, and the device comprises an optical fiber connection protection box, an analyzer integrated protection box, a filter, a power supply, an industrial personal computer, an optical path box, an optical fiber sensing analyzer, an input / output interface, and an indicating lamp. The filter, the power supply, the industrial personal computer, the optical path box and the optical fiber sensing analyzer are fixed in the main body of the analyzer integrated protection box. The input / output interface and the indicating lamp are disposed on the housing of the analyzer integrated protection box. The optical fiber connection protection box is independently disposed nearby the analyzer integrated protection box through an optical fiber. The device is simple in structure, is high in reliability, can effectively measure the partial deformation of a measured object, and can still work effectively when the optical fiber sensing analyzer has a fault. Meanwhile, when the optical fiber sensing analyzer has the fault, the optical fiber sensing analyzer can be replaced conveniently.

Description

technical field [0001] The invention relates to a device in the technical field of ocean engineering, in particular to an optical fiber acquisition and analysis device capable of double backup for ocean engineering. Background technique [0002] It is a realistic demand to measure the local strain of large offshore structures under actual working conditions. Because the environment of large offshore structures is usually high humidity, high salinity, exposure to the sun, and due to the vibration of large offshore structures, the optical fiber acquisition and analysis devices that generally work stably on land cannot be effective on large offshore structures. use. Through actual use, it is found that if the optical fiber acquisition and analysis device used on land is directly installed on a large offshore structure, the instrument will break down in a short time, resulting in large errors in measurement data, unusable measurement results, and even damage to the instrument. ...
