Flight parameter system testing platform and method based on PXI bus

Abstract

The invention belongs to the field of aerospace electronic testing and relates to a flight parameter system testing platform and method based on a PXI bus. At present, for flight parameter system testing, universal testing devices suitable for flight parameter system testing and based on a VXI bus or PCI bus are generally adopted and have the shortcomings of single signal type and insufficient signal channels. The flight parameter system testing platform based on the PXI bus comprises a PXI testing device, a power supply control box, a direct-current program control voltage-stabilizing power supply and a KVM display. Based on the flight parameter system testing platform, modules on the PXI bus are driven through a PXI controller to output simulation signals to a flight parameter system, and data recorded by the flight parameter system is downloaded and is compared with originally uploaded data. The cost is reduced, and functions of real-time dynamic signal simulation, synchronous signal simulation, switch quantity valve value testing and the like are provided.

Description

technical field [0001] The invention belongs to the field of avionics testing, and relates to a test platform and method for a flight reference system based on a PXI bus. Background technique [0002] The flight reference system is a device that automatically collects and records various flight data, audio data and video data according to the agreed format during the flight of the aircraft. These data reflect the working status of the aircraft and the operation of the pilot during the flight. The performance, quality, and accuracy of recorded data of the flight reference system directly affect the daily maintenance of the aircraft, the elimination of hidden troubles, the development of new models, and the search and rescue of aircraft crashes. [0003] At present, the test of the flying reference system usually adopts the general test equipment based on the VXI bus or PCI bus suitable for the test of the flying reference system, which has a single type of signal, insufficien...
