The invention discloses an aviation bus general test device and test method, the device comprises a cabinet and a host computer, the cabinet is internally provided with a mother board and an adapter plate, the mother board is provided with a CPU module and an FPGA module, the adapter plate is electrically connected with the FPGA module, and the adapter plate is provided with an aviation bus daughter card seat for plugging an aviation bus daughter card to be tested. The upper computer obtains analysis data matched with the bus type of the to-be-tested aviation bus daughter card and sends the obtained analysis data to the FPGA module, and the FPGA module conducts bus protocol analysis on data exchanged between the to-be-tested aviation bus daughter card and the CPU module according to the received analysis data. The test device and the test method provided by the invention can be compatible with various types of aviation bus protocols, can effectively detect working faults of the aviation bus daughter cards in low-temperature / high-temperature and vibration environments, screen out the defective aviation bus daughter cards in time, and ensure normal communication of an aviation bus system.
Description
technical field [0001] The invention relates to the technical field of aviation airborne equipment, in particular to an aviation bus universal testing device and testing method. Background technique [0002] As an important part of the airborne avionics system, the aviation bus is used to complete the high-speed communication between the various subsystems of the avionics equipment, so it is of great significance to ensure flight safety. [0003] The aviation bus communication sub-card is an important communication component of avionics equipment and plays an important role in the communication of the avionics system. Therefore, the high-reliability aviation bus communication sub-card is of great significance to the normal operation of avionics equipment. Since the aircraft has experienced harsh natural environment, electromagnetic environment and vibration environment throughout its service, from take-off to landing, from low temperature to high temperature, it has experien...
