Study on File-based Transfer of MIL-STD-1553B Data Bus

MIL-STD-1553B data bus is applied in the transmission of periodic signals with a small amount and minimal aperiodic signal.Requirement of file transfer based on 1553B data bus is proposed to simplify the design of mission data transfer in the airborne environment.The format of word and message of 1553B data bus is introduced briefly,and the transfer method of bulk data based on full frame and last frame is presented,and the frame of file information and file data is constructed,and time sequence and the process of sending and receiving of file transfer are analyzed.The file transfer from BC to RT is achieved by designing a new mode command word,and the asynchronous communication of file transfer requested by RT is implemented by the design of the word vector.
