Embodiment Construction

[0021] The present invention will be further described in detail below by taking the specific design of the avionics system as an example.

[0022] 1. Model Development

[0023] The PHM model development of the avionics system is based on data such as "four characteristics" (reliability, testability, maintainability, and safety), and the model is developed with the help of model development tools and general toolboxes, and the integrity of the knowledge model can be checked and consistency, the user makes modifications according to the error information fed back by the tool software. Model development is divided into model development based on design data and model development based on data mining.

[0024] The process of model development based on design data such as figure 2 shown.

[0025] (1) Data preparation or knowledge extraction

[0026] The data preparation stage is to extract the diagnosis logic and fault attributes of each failure mode through sorting out and a...

Abstract

The invention relates to a method for designing a PHM (Prognostic Health Management) system model development and verification platform, which is used for supporting development and simulation verification for a PHM system model and algorithm of aviation equipment. The design method of the invention comprises a PHM model development method, a data management method and a PHM model simulation verification method. The PHM model development and verification platform can solve a problem of model engineering development and verification, and performs effective modification on the model according toa verification result, thereby improving the fault detection rate and isolation rate of the equipment and system, and achieving a purpose of saving the maintenance time and the maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of fault prediction and health management (PHM). Background technique [0002] The development and verification platform design method of the PHM model, as a key technology to realize new ideas and new solutions such as state-based maintenance of weapons and equipment, autonomous support, and perception and response logistics, has been highly valued and promoted by military powers such as the United States and Britain. However, the technical achievements of the development and verification of the PHM model are various and emerge in endlessly at home and abroad, most of which are limited to specific equipment objects and lack generality; or they focus on academic exploration and lack consideration of generality and engineering. As for the key technologies of model development and verification that have been successfully applied abroad, China is subject to strict technical blockade. Contents of the invention...
