Description

technical field [0001] The present invention relates to a ground comprehensive test system for flight data recording equipment, in particular to an instrument simulation multi-channel actual airborne signal driven by real flight data, which is used as the signal source of the flight data recording equipment and comprehensively tested on the ground. Test evaluation of flight data recording equipment ground integrated test system. Background technique [0002] In the field of aerospace, flight parameter data has important reference and application value. In addition to using the flight parameter data to investigate the cause of the accident of the crashed aircraft, the flight parameter data can also be used to test the design performance of the aircraft, monitor the health status of the aircraft, fault diagnosis and trend prediction, etc. Obtaining flight parameters is mainly achieved in two ways: ① the ground station uses the communication system to directly communicate with...

Problems solved by technology

Therefore, today's flight data recording functions are more and more, and the structure is more and more complex

[0003] At present, in the research and development process of flight data recording equipment, the test of the product is simply provided with a small number of analog signals, discrete signals or bus signals for its collection. Testing can only be done through field test flights, which are expensive, time-consuming and dangerous
