Abstract

The invention relates to a flight data recording equipment ground integrated test system which comprises a main control computer, a simulation control computer, a verification control computer, a signal simulation sub-system, a signal simulation sub-system, a communication network sub-system and a synchronous trigger system. The main control computer completes functions of user management, report output, flight data interpretation and the like, the simulation control computer is a control main center of the signal simulation sub-system, the verification control computer is a control main center of the signal verification sub-system, the signal simulation sub-system outputs all kinds of real time simulation signals, the signal verification sub-system is composed of testing apparatus and verifies the correctness or the precision of the simulation signals output by the signal simulation sub-system, the communication network sub-system is a communication platform between computers and the testing apparatus in the system, and synchronous trigger system realizes the clock synchronization and trigger synchronization of the signal simulation sub-system and the signal simulation sub-system. The flight data recording equipment ground integrated test system provides an accurate signal source to the full test of ground environment flight data recording equipment.

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...
