Research on Embedded Real-time Processing Technology of ARINC429 Bus Dynamic Logic BlockARINC429 bus is widely used. In a new type of logic block communication method, the logic layer of the application layer is composed of a plurality of ARINC429 messages, and the message length and content dynamically change. The telemetry monitoring needs real-time analysis of the application layer communication protocol to correctly interpret the user-defined message content. This paper proposes an embedded real-time processing scheme, which integrates real-time processing hardware and software in data acquisition unit. It can dynamic analysis the application layer protocol of the logic block, extract user-defined information according to the telemetry for downloading, the problems encountered in telemetry monitoring of the type of communication are solved. At the same time, this solution is also applicable to real-time analysis of other avionics bus in the application layer protocols.
