Abstract

The invention relates to the technical field of aviation airborne tests, and provides a recorder general test device based on a PXI bus. According to the device, defects of large size, high cost, test resource waste, equipment non-integration and non-purpose of a conventional flight parameter test device based on VXI are solved for the test of a recorder. According to the device, by employing the PXI technology, a controller, a display, an input device, and recorder general signal source boards are integrated in an PXI cabinet; by installing test software, the PXI controller is driven, signal source modules and a simulation collector are controlled, and flight data and audio and video data are sent to the recorder; and after completion of record, the data is downloaded and compared with original sent or uploaded data, and whether data results are consistent is determined. According to the recorder general test device, the size is small, the weight is low, various intelligent modules are integrated, functions are complete, and the test device is applicable to test requirements of protection recorders, cache recorders, and waterborne floating recorders.

Description

technical field [0001] The invention relates to the technical field of avionics testing and provides a recorder general testing device based on a PXI bus. Background technique [0002] The flight parameter recorder is a device that automatically records various flight data, audio data and video data in an agreed format during the flight of the aircraft. These data reflect the working conditions of the aircraft and the operation of the pilot during flight. The performance, quality, and accuracy of recorded data of the recorder 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 flight parameter recorder usually adopts the general-purpose test equipment based on the VXI bus suitable for the test of the collector, which has the characteristics of large size, heavy weight, inconvenient movement, etc., and the cost is high, the ...
