Abstract

The invention provides an optical fiber point type temperature vibration sensing device and system, relating to the technical field of sensing equipment. The optical fiber point type temperature vibration sensing device comprises a shell, an incident flange, an emergent flange, a fixed buckle and a sensing element, wherein the incident flange and the emergent flange are arranged on the shell, thefixed buckle is arranged in the shell, the sensing element is fixedly mounted on the fixed buckle, and the incident flange, the sensing element and the emergent flange are connected with a measurementoptical fiber in series. According to the device, the problem that the user experience level of the measurement, aiming at a specific point, of an existing optical fiber temperature measurement and vibration measurement system is low can be relieved, and the user experience level can be increased; and meanwhile, the measurement precision of a measurement point can be increased, and besides, the device has the advantages of simplicity and convenience in use and simple structure, is convenient to carry and test and is applicable to multiple types of sensing systems.

Description

technical field [0001] The invention relates to the technical field of sensing equipment, in particular to an optical fiber point type temperature vibration sensing device and system. Background technique [0002] At present, common fiber optic temperature measurement technology solutions include scattering-based line distributed fiber optic temperature measurement systems, such as Raman scattering-based line distributed fiber optic temperature measurement systems, fiber grating-based point fiber optic temperature measurement systems, etc. Common optical fiber vibration measurement technology solutions include Rayleigh scattering-based line-distributed optical fiber vibration measurement system and fiber grating-based point fiber vibration measurement system. [0003] However, the distributed optical fiber temperature measurement and vibration measurement system based on scattering is not accurate enough for the measurement of specific points, and is easily affected by syste...
