Two-dimensional fiber bundle micro vibration fiber sensor and using method thereof

Abstract

The invention discloses a two-dimensional fiber bundle micro vibration fiber sensor and a using method thereof. The two-dimensional fiber bundle micro vibration fiber sensor comprises an outer shell, a fiber pivot frame, a fiber connector, a fiber bundle, a first adapter, an image conversion device for processing optical signals, and a fiber bundle connector for connecting the first adapter and the image conversion device, wherein the image conversion device is composed of an image converter, a second adapter connected with the image converter, an electrical signal output port and a power interface. According to the two-dimensional fiber bundle micro vibration fiber sensor using method, the length of the fiber bundle connector is adjusted, the outer shell of the two-dimensional fiber bundle micro vibration fiber sensor is partially arranged on a detected object, and the image conversion device is placed at another place. The problems of online detection and high sensitivity which can not be solved by the prior sensor can be solved, the sensor can resist high voltage, strong magnetic field, and radiation, and is simple in manufacturing and structure, and large instrument equipment, operating equipment and the like can be ensured to work normally.

Description

technical field [0001] The invention relates to a vibration sensor, in particular to a two-dimensional optical fiber bundle micro-vibration optical fiber sensor and a using method thereof. Background technique [0002] When large-scale equipment and operating equipment are working, there will be a certain range of small vibrations. Under normal circumstances, the amplitude of this vibration will not exceed a certain range. When the equipment and operating equipment are working abnormally, the vibration will also appear. abnormal. In many cases, we hope to know the specific size and direction of this vibration, so as to obtain the critical value of abnormal vibration in time, and take measures to eliminate major accidents in instruments, flight and operation equipment. [0003] In the early days of measuring vibration displacement, levers or gears / racks were used to amplify. This type of meter has disadvantages such as wear, inconvenient reading, and inability to transmit vi...

Problems solved by technology

In addition, environmental noise, sensor installation method and wire laying method all have a great influence on the detection results

[0004] The sensing detectors of foreign testing instruments mainly have optical vibration sensing, and the sensing is composed of spring plates loaded with gratings: there are many occasions that require micro-vibration sensing probes not to be charged, and need to work in an environment of electromagnetic interference, and some The requirement must be detected online, so it cannot meet the requirement
