Abstract

The present invention relates to a vibration detection structure, comprising a light source assembly and a receiving induction assembly arranged above the light source assembly; the light source assembly includes a first grating electrode, a second grating electrode is arranged above the first grating electrode, and the second grating electrode is arranged above the first grating electrode. A light-emitting block is arranged between the first grating electrode and the second grating electrode; the vibration detection structure not only has high sensitivity, but also is not easily disturbed by electromagnetic fields, has a simple structure, and can be made into a smaller sensor or vibration detection device. It can be applied to the application field with complex electromagnetic environment and narrow space. On the other hand, it can adjust the vibration characteristics by changing the temperature of the heating plate, thereby changing the vibration frequency to be monitored, and the optical characteristics are stable and have self-recovery function.

Description

technical field [0001] The invention relates to the technical field of vibration detection, in particular to a vibration detection structure. Background technique [0002] Vibration is a common physical phenomenon in engineering technology and daily life. In most cases, vibration is harmful, and it will affect the accuracy, life and reliability of instruments and equipment. Of course, vibration also has a side that can be used, such as conveying, cleaning, grinding, monitoring, etc. For example, a vibration detector is an instrument for measuring the vibration of an object, and it is widely used in bridges, buildings, earthquakes and other fields. The vibration detector can also form a vibration measurement system with the acceleration sensor to measure the acceleration, velocity and displacement of the object. [0003] Whether using vibration or preventing vibration, the intensity of vibration must be monitored. In the prior art, the vibration monitoring method is genera...
