A hierarchical and integrated vehicle fleet health management system architecture

Abstract

The invention discloses a layered and integrated vehicle unit health management system architecture, which belongs to the field of artificial intelligence technology. In the architecture, the state awareness layer is used to measure the health state parameters of each subsystem of the vehicle; the functional subsystem area management layer is at least used to make exceptions for each subsystem based on the health state parameters of each subsystem and the performance evaluation model of each subsystem. Detection, predictive reasoning and diagnostic reasoning; the vehicle system health management layer is used to perform anomaly detection, predictive reasoning and diagnostic reasoning on the whole vehicle according to the data sent by each system and the vehicle performance evaluation model; the team health management layer includes the ground system, and its At least it is used to process the data of the vehicle and its subsystems according to the data sent by the vehicle system health management layer, and use the artificial intelligence module to train the model. The architecture provided by the present invention makes full use of the redundant information among the health status information, improves the reliability of the diagnosis and prediction of the vehicle and its subsystems, and realizes the distributed perception, hierarchical evaluation, integrated decision-making and Precise application.

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...

AI Technical Summary

Problems solved by technology

However, the reliability of system-level diagnosis / prediction is relatively low because the test results of each subsystem are not effectively integrated, and the redundant information among the health status information cannot be effectively used.
