Multichannel fiber bragg grating demodulation system

Abstract

The invention provides a multichannel fiber bragg grating demodulation system. The multichannel fiber bragg grating demodulation system comprises a fiber bragg grating demodulator and a portable box body, the portable box body comprises a box body and a box cover, a rectangular mounting groove is formed in the middle of the top face of the box body, positioning assemblies are symmetrically arranged on the upper portions of the groove walls of the left side and the right side of the rectangular mounting groove, a buffer pad is arranged in the middle of the groove bottom, each positioning assembly comprises a containing cavity formed in the middle of the side wall of the box body, and the side, close to the middle of the box body, of each containing cavity communicates with the rectangular mounting groove; and a limiting plate capable of sliding left and right is cooperatively installed in the storage cavity, a spring assembly is arranged between the limiting plate and the side, away from the middle of the box body, of the storage cavity, limiting columns are further arranged on the front side and the rear side of the limiting plate, and strip-shaped limiting sliding grooves are further formed in the front side and the rear side of the storage cavity. The box body is designed to be easy to disassemble and assemble, installation and taking out of the fiber bragg grating demodulator are facilitated, time is saved for instrument maintenance and debugging, maintenance efficiency is improved, and the installed fiber bragg grating demodulator is stably fixed in the box body.

Description

technical field [0001] The invention relates to the technical field of fiber grating demodulation, in particular to a multi-channel fiber grating demodulation system. Background technique [0002] Fiber Bragg grating demodulation system is an instrument used in the field of mechanics and physics, with high power and fast scanning function; it is a complete system with scanning light source, which can simultaneously measure the optical signal reflected by each optical fiber. At present, although a portable fiber grating demodulator has been designed, it is directly fixedly connected to the external box body. When maintenance is required, it is cumbersome to disassemble, time-consuming and laborious, and greatly increases the maintenance time. Contents of the invention [0003] To solve the above problems, the invention discloses a multi-channel fiber grating demodulation system. [0004] The specific plan is as follows: [0005] A multi-channel fiber grating demodulation ...

AI Technical Summary

Problems solved by technology

At present, although a portable fiber grating demodulator has been designed, it is directly and fixedly connected to the external box. When maintenance is required, it is cumbersome to disassemble, time-consuming and laborious, which greatly increases the maintenance time.
