[Abstract]:Aviation bus fibre Channel (FC) is gradually replacing the traditional 1553B and becoming the architecture protocol of the new generation avionics system. FC bus has the characteristics of large amount of data, at the same time, the flight test engineers need to deal with more and more messages, which puts forward higher requirements for multi-subject data processing of FC bus. In view of the characteristics of multi-subject bus data processing in flight test, a multi-subject data processing method of flight test avionics bus based on balanced thread group is proposed, which breaks the traditional multi-subject processing mode of flight test avionics bus. The multi-subject processing efficiency of flight test avionics bus is improved. Finally, it is applied in flight test of a certain testing machine. The experimental results show that its processing efficiency is 40 times higher than that of traditional flight test avionics bus processing technology. The problem of multi-subject data processing in mass test FC avionics bus is solved, and the requirement of multi-subject processing in modern flight test FC is satisfied.
