Flight vehicle health state monitoring system based on distributed optical fiber sensing

Abstract

The invention discloses a flight vehicle health state monitoring system based on distributed optical fiber sensing. The flight vehicle health state monitoring system comprises a motion detection unit, an operation detection unit, an atmospheric environmental indicator detection unit, a central processor, an early warning unit, and a wireless communication module. The motion detection unit is used for the real-time detection of the flight velocity and the flight height of the flight vehicle. The operation detection unit is used for the real-time detection of the attitude information, the pressure-bearing information, and the vibration information of the flight vehicle. The atmospheric environmental indicator detection unit is used for real-time detection of air temperature, dust concentration, and illumination intensity. The system is used for the comprehensive monitoring and analysis of the main rotor, the tail rotor, the transmission system, the parts of the engine of the flight vehicle by using external sensors to realize the integral health monitoring of the flight vehicle. The health state fault of the flight vehicle is diagnosed and predicted, and powerful data support is provided for the health monitoring, and therefore the targeted, timely, and effective maintenance of the flight vehicle is realized, and good economic benefits and good military benefits are provided.

Description

technical field [0001] The invention relates to the technical field of intelligent sensing, in particular to an aircraft health status monitoring system based on distributed optical fiber sensing. Background technique [0002] With the rapid development of aircraft research and development and application, the requirements for the aircraft's information maintenance support system are also getting higher and higher. At present, the detection equipment used for fault diagnosis and maintenance of aircraft in my country is not highly integrated and bulky, and it is not easy to collect in-flight information in real time during the flight state of the aircraft and perform fault analysis and processing, resulting in inadequate equipment maintenance and failure to determine in time after a fault occurs Faulty parts, long maintenance cycle and other problems. Contents of the invention [0003] The purpose of the present invention is to provide an aircraft health status monitoring s...
