A launch vehicle health monitoring system and method

Abstract

The invention discloses a carrier rocket health monitoring system and method. The method is provided for the specific measurement and launching complexity of a new generation of large-scale low-temperature carrier rocket. Mainly oriented to moon exploration, fire detection engineering narrow window and zero window emission task requirements are met; The system comprises a man-machine interaction subsystem, The system comprises a data service subsystem, a data management subsystem and a data acquisition subsystem, applies the technologies of big data, image recognition, voice recognition and intelligent search, makes full use of test data of multiple times and multiple fields, and achieves the functions of real-time health monitoring, rapid data analysis, auxiliary fault analysis and positioning and emission plan support of test and emission control of a large-scale low-temperature carrier rocket.

Description

technical field [0001] The invention relates to a carrier rocket health monitoring system and method, belonging to the technical field of carrier rocket monitoring. Background technique [0002] Due to the complexity of the new generation of large-scale cryogenic launch vehicles and the development of electrical testing and measurement and control technologies, the scale of measuring points and data used to characterize and monitor the rocket’s health status is increasing, and each test generates a large amount of test data. When on-site personnel make online judgments or post-interpretations, the problem of missed judgments is prone to occur. At the same time, a large amount of expert knowledge is scattered in various design documents, which is difficult to quickly apply in troubleshooting. When an emergency occurs, it is not conducive to timely search on site. The comprehensive ability of the principle / knowledge reserve and on-site disposal of on-site personnel is put forw...

AI Technical Summary

Problems solved by technology

[0002] Due to the complexity of the new generation of large-scale cryogenic launch vehicles and the development of electrical testing and measurement and control technologies, the scale of measuring points and data used to characterize and monitor the rocket’s health status is increasing, and each test generates a large amount of test data. On-site personnel make online judgments or post-interpretations, which is prone to missed judgments

At the same time, a large amount of expert knowledge is scattered in various design documents, which is difficult to quickly apply in troubleshooting. When an emergency occurs, it is not conducive to timely search on site. The comprehensive ability of the principle / knowledge reserve and on-site disposal of on-site personnel is put forward. Extremely high requirements, unable to meet the high response timeliness requirements of subsequent major national projects for rapid investigation, rapid positioning, and rapid disposal

At present, the information of rocket testing and pre-launch monitoring mainly depends on the online data of each system, and the testing information is relatively simple, and a large amount of image information and sound information in the testing site have not been acquired and applied.
