Abstract

The present invention relates to micro-vibration optic fiber sensor of 2-D optic fiber cluster and its operating method. Micro-vibration optic fiber sensor of 2-D optic fiber cluster comprises housing, supporting point member for optic fiber, coupler for optic fiber, optic fiber cluster, first accommodator, image converting device for processing of optic signals, coupler for optic fiber cluster coupling the first accommodator to the image converting device. The image converting device comprises image converter, second accommodator coupled to the image converter, output port for electric signals and power connectors. The operating method of the micro-vibration optic fiber sensor of 2-D optic fiber cluster is that adjusting the length of the coupler of the optic fiber cluster, installing the housing of the micro-vibration optic fiber sensor of 2-D optic fiber cluster on the sensed object, and placing the image converter at another location.

Description

1. 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 usage method. 2. Background technology:

[0002] When large-scale instruments and 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 equipment such as equipment and operation work 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 immediately, and take measures to rule out major accidents in equipment, flight and operation.

[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 vibration signals. Ac...
