Research on Embedded Device Data Standardization Technology Based on OSA-CBM

Aiming at the problem that the data communication standards of airborne equipment of different suppliers are obviously different and it is difficult to trace and identify the data transmission between them, it is proposed to standardize the data of airborne equipment based on OSA-CBM standard, create dynamic data models for transmission and static data models for tracing and identification in six functional blocks. In addition, the embedded data processing flow is designed to realize the functions of data acquisition, data processing and state detection in the embedded system. Through instantiation verification of typical embedded equipment on board, evaluate the performance difference between non standardized and standardized embedded equipment data, and verify the interoperability, traceability and identifiability of the data model. It lays a foundation for airborne equipment health management and fault diagnosis, and has engineering application value in airborne embedded equipment condition based maintenance strategy.
