Preparation device and preparation process of Brillouin sensing intelligent rib

Abstract

The invention discloses a preparation device of a Brillouin sensing intelligent rib, and relates to the technical field of protective doors. Comprising a traction device and a fiber creel, the fiber creel fixes one end of a fiber yarn bundle, the other end of the fiber yarn bundle enters a resin tank through a guide plate, the resin tank merges the fiber yarn bundle and passes through a creel, the creel merges the passing fiber yarn bundle with a sensing optical fiber, and the sensing optical fiber passes through the creel. And the fiber yarn bundle and the sensing optical fiber pass through a combined mold. The device has the advantages that the sensing optical fiber and the fiber yarn bundle are synchronously transmitted, the sensing optical fiber is arranged in the center of the intelligent rib, and the sensing optical fiber and the fiber yarn bundle body of the intelligent rib are compactly combined; an advanced ultraviolet irradiation curing process is adopted, irradiation point positions are sectionally controllable, irradiation light intensity is sectionally adjustable, curing quality and production efficiency are improved, the defect that a previous drying tunnel is too long is overcome, and the whole production line is smoother and more compact.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a preparation device for a Brillouin sensing smart rib and a preparation process thereof. Background technique [0002] Due to its own advantages and broad application prospects, Brillouin distributed optical fiber sensor technology has become a rookie in sensors at home and abroad. Brillouin optical time-domain reflectometry (BOTDR) based on Brillouin scattering and Brillouin optical time-domain analysis (BOTDA) fiber optic sensing technology based on stimulated Brillouin scattering are widely used in the continuous distribution of parameters such as temperature and strain formula measurement. Distributed optical fiber strain and temperature sensors have many advantages such as small size, light weight, no electromagnetic interference and long-distance sensing. They are widely used in forest fire prevention warning, oil pipeline intrusion warning, and large building heal...
