Abstract

The invention discloses a hierarchical fusion type vehicle unit health management system architecture, and belongs to the technical field of artificial intelligence. In the architecture, a state sensing layer is used for measuring health state parameters of each subsystem of a vehicle; a functional subsystem area management layer is at least used for performing anomaly detection, predictive reasoning and diagnostic reasoning on each subsystem according to the health state parameters of each subsystem and the performance evaluation model of each subsystem; a vehicle system health management layer is used for performing anomaly detection, predictive reasoning and diagnosis reasoning on the whole vehicle according to data sent by each system and a vehicle performance evaluation model; and a unit health management layer comprises a ground system which is at least used for performing data processing on the vehicle and each subsystem according to the data sent by the vehicle system health management layer, and training a model by using an artificial intelligence module. According to the architecture provided by the invention, redundant information among health state information is fully utilized, so that the diagnosis and prediction credibility of the vehicle and subsystems thereof is improved, and distributed perception, hierarchical evaluation, integrated decision and accurate application of vehicle health management are realized.

Description

technical field [0001] The invention relates to a layered and integrated vehicle unit health management system framework, which belongs to the technical field of artificial intelligence. Background technique [0002] Prognosis and Health Management (PHM) system structure refers to the basic organization of the PHM system, which is manifested in the interrelationships between components of the PHM system, the interrelationships between components and the environment, and the principles of design and evolution. It describes the PHM system The entities of the architecture and their characteristics determine the relationship between the components of the PHM system architecture. PHM system structure design technology is a bridge between PHM system requirement analysis and PHM system design and implementation, and is the foundation and key to construct PHM system. A good system structure can reduce the complexity of PHM system design and development, and facilitate the implementa...
