Embodiment Construction

[0072] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0073] Such as figure 1 As shown, an autonomous fault diagnosis and intelligent maintenance system for a reusable vehicle adopts a three-level multi-signal flow transmission model, which is a subunit, an area manager, and a platform manager.

[0074] The sub-unit is used to collect the basic information of the bottom layer, including various physical quantities such as voltage, current, overload, temperature, air pressure, etc., and convert it into an electrical signal and transmit it to the area manager. The sub-unit can be an independent sensor or a Acquisition circuit, etc.;

[0075] The area manager is used to receive the underlying basic information transmitted by each sub-unit, and perform area-level processing to achieve first-level isolation of faults within the area;

[0076] The platform manager is used to receive the fault diagno...

Abstract

The invention relates to an autonomous failure diagnosing and intelligent maintenance system and method for a carrier capable of being used repeatedly based on a plurality of signal flows, and belongsto the technical field of spacecraft failure diagnosis and maintenance security. According to a failure diagnosis result, a maintenance method with the period and the expenditure being optimized is intelligently reckoned, intelligent maintenance is achieved, accordingly the problems that ''a manual loop'' for diagnosing failures of the carrier capable of being used repeatedly is large in participation quantity, has a certain hysteretic nature, long in maintenance period and high in cost are solved, rapid online failure diagnosis and intelligent maintenance of the carrier capable of being usedrepeatedly are achieved, and the autonomous failure diagnosing and intelligent maintenance system and method are beneficial for providing technical support for achieving rapid and repeated usage of the carrier.

Description

technical field [0001] The invention relates to an autonomous fault diagnosis and intelligent maintenance system and method for a reusable carrier based on multiple signal streams, belonging to the technical field of spacecraft fault diagnosis and maintenance support. Background technique [0002] The autonomous fault diagnosis and intelligent maintenance method based on multiple signal streams is a key technology for rapid autonomous diagnosis and maintenance of reusable vehicles. As far as the reusable vehicle is concerned, it needs to go through ①ground preparation stage -> ②ascent stage->③in-orbit operation stage->④re-entry return stage->①ground preparation stage->..., various flight mission stages are harsh Environmental conditions lead to complex force, heat, electromagnetic and space environment for the vehicle. Different from traditional vehicles, reusable vehicles need to realize re-entry and return and perform missions again after landing inspection...
