Abstract:

In order to solve the problem of the single function of the test equipment of serial aviation bus, a portable universal serial bus integrated test system is designed. Scheme of modular design, detailed description of the hardware and software design of the system, the system by the universal serial bus terminal equipment simulation and test analysis of the composition of the equipment, the system involves a variety of serial aviation bus, can complete the multi bus simulation excitation output, monitoring receiving and data simulation analysis function, can satisfy the needs of the aviation equipment and system simulation electronic system. The experimental results show that the system has the advantages of good stability, high reliability and convenient use.
