Design of data preprocessing software for military 1394b bus

This paper studies the military 1394b bus data format of airborne acquisition records based on asynchronous stream packet and the ICD information file format associated with the bus data, extracts the important information related to the data analysis from the ICD information, designs the data analysis configuration information field table, and constructs the ICD information management database, so as to ensure the accuracy and consistency of the configuration information, and ensures The correctness of data analysis; According to the characteristics of data format, designs a data processing algorithm based on message frame, meanwhile, Combined with double buffering technology, ensures the efficiency of data processing; Using modular software design ideas and C+ + language coding to achieve the military 1394b bus data preprocessing. Practice shows that the software can well satisfy the requirements of flight test data processing tasks.
