Spacecraft structure multi-functional health monitoring system and method

Abstract

The invention provides a spacecraft structure multi-functional health monitoring system and method, which are used for solving the problems of excessive spacecraft monitoring equipment and no data integration in the prior art. According to the spacecraft structure multi-functional health monitoring method, a data integration processing module is connected with an external power supply and transmits the data to other modules, set acquisition parameters and acquisition start and stop instructions are issued to the other modules, and three monitoring modules acquire data and then send the data tothe data integration processing module; and after the collected data is received, the structure temperature, the strain state, the elastic guided wave and the acoustic emission data are integrated, and the temperature curve, the crack damage, the collision damage and the leakage state are analyzed and displayed. According to the invention, integrated acquisition and data integration and analysisof multiple parameters of the spacecraft structure are realized, health states such as geometric structure, strain and temperature of the spacecraft are monitored more efficiently and conveniently, early warning is carried out on damages such as cracks, collision and leakage, and the safety and reliability of the spacecraft are ensured.

Description

technical field [0001] The invention belongs to the field of spacecraft structure monitoring, and in particular relates to a multifunctional health monitoring system and method for a spacecraft structure. Background technique [0002] The space station and other spacecraft have complex structures, and the load environment such as force and heat during launch and on-orbit operation is harsh. Sensors for monitoring its vibration, strain, acceleration, temperature and other structural states are deployed on the airtight cabin of manned spacecraft. Sensors for monitoring whether space debris collisions occur in the airtight cabin, or even cause the airtight cabin to leak, and data collection and The analysis device conducts data analysis on the vibration, temperature, speed, leakage and other signals collected by the sensor, and evaluates the health status of the spacecraft structure. [0003] In the prior art, for different structures of spacecraft, different monitoring princi...

Problems solved by technology

However, when conducting comprehensive state monitoring and abnormal judgment on the spacecraft structure, it is necessary to call various state monitoring data separately; at the same time, various data are independent of each other, and the value of monitoring data cannot be fully realized.
