Example Embodiment

[0020] Such as figure 1 As shown, first, when the aircraft cabin body 1 is processed, the longitude fiber groove 2, the latitude fiber groove 3, the longitude entry hole 4, and the latitude entry hole 5 are set in advance during the structural processing of the aircraft cabin body 1. Among them, the longitude entry holes 4 are located at the two ends of the aircraft cabin 1 structure, and the latitude entry holes 5 are scattered and independently opened on the circumference of the aircraft cabin 1 structure.

[0021] Put the longitude or latitude optical fiber sensor 11 into the corresponding longitude or latitude optical fiber groove 10 in sequence, and fill and fix it with adhesive 12. The longitude optical fiber sensors 11 that are about to enter the cabin at different positions can be gathered at the latitude optical fiber grooves 3 at both ends, and guided to the corresponding longitude entry hole 4; the multiple longitude optical fiber sensors 11 are assembled into a bundled...

Abstract

Disclosed is a method for embedding optical fiber sensors in an aircraft cabin. A plurality of longitudinal grooves and a plurality of transverse grooves are formed in the surface of the aircraft cabin in advance, longitudinal cabin inlets are reserved in the two ends of the aircraft cabin, transverse cabin inlets corresponding to the transverse grooves one to one are formed in the circumference of the aircraft cabin, the multi-path optical fiber sensors are distributed in the multiple longitudinal grooves and the transverse grooves, the grooves are filled with glue and fixed, and then the optical fiber sensors can be embedded in the surface of the aircraft cabin. The multi-path optical fiber sensors pass through the corresponding longitudinal cabin inlets and the transverse cabin inlets, then enter the aircraft cabin, are gathered at the two ends of the cabin to form optical fiber bundles, are integrated to an optical fiber connector and then are connected with an information collection device or communicated with an adjacent cabin. By the method, the optical fiber sensors can be embedded in the surface of a single-cabin or multi-cabin butt joint type aircraft, an optical fiber sensing and detecting network is achieved, the mechanical property and damage situations of the aircraft cabin can be monitored comprehensively, and the method has the advantages that reliability is high and operation is easy.

Description

technical field [0001] The invention relates to a method for pre-embedding an optical fiber sensor in an aircraft cabin, which realizes the purpose of an aircraft optical fiber intelligent structure, and is used for state monitoring and damage detection of the aircraft cabin structure. Background technique [0002] The intelligent structure is to embed or paste sensors in the substrate, so that it can perceive its own actual state, and realize various functions such as self-detection, self-diagnosis, self-monitoring, self-repair and self-adaptation under dynamic or online conditions. Its research began in the 1980s. The US government first proposed to carry out research in this area, and then other developed countries and regions in the world have successively carried out research on intelligent structures. In the 1990s, its potential application value in the military and civilian fields has attracted great attention, and the research on intelligent structures is unprecedent...
