| Abstract: |
| According to the requirements of highly integrated modular airborne system for high safety,high reliability and easy maintenance,an integrated condition monitoring and diagnostic architecture based on the “health management domain” is proposed to solve the problem of comprehensive integration of diagnostic elements of multi-level airborne system under the conditions of multiple aircraft platforms and usage scenarios.Due to the highly integrated circuit design of airborne system,the software logic test and anomaly detection model are introduced,and the comprehensive condition monitoring method of general module,functional thread and data bus network is proposed,which can improve the online health perception ability of airborne system without increasing extra hardware.The loosely coupled and modular “health management domain” is designed,the general software structure of health assessment and diagnostic model is defined,and the multi-model integration algorithm framework of mechanism data fusion is proposed,which solves the problems of knowledge migration among multi-aircraft platform diagnostic models and multi-usage scene differential model fusion application.The graphical display and control interface and object-oriented database are developed,which improves the interface friendliness and functional scalability of the condition monitoring and diagnostic system.The architecture is applied to integrated modular airborne mission systems to develop the condition monitoring and diagnostic subsystem. |
