| Abstract: | 1553B bus is a kind of serial data bus,which is widely used in spacecraft.The reliability of 1553B bus is correlative with the reliability and function of the satellite.The proximate bus message overcast to the same terminal is a kind of typical problems which effects the reliability of 1553B bus onboard.This paper deeply analyzes the problem,also resolved the puzzle of obtaining the critical time gap value for the same terminal message overcast through 80C31/80C32 singlechip RT experiment.Base on it,three ... |
