Aviation bus test card based on FlexRIO

Abstract

The invention discloses an aviation bus test card based on FlexRIO. The aviation bus test card is connected between an aviation bus and an avionics test system to implement tests for the aviation bus. The aviation bus test card comprises an adapter and a FlexRIO FPGA card which are connected to each other, wherein the adapter is connected with the aviation bus, and the FlexRIO FPGA card is connected with the avionics test system through a PXI bus. The aviation bus test card disclosed by the invention has the beneficial effects as follows: the adapter disclosed by the invention can be adapted to various FlexRIO FGPA cards, has strong universality, can make good use of the existing test resources, ensures that the utilization rate of the resources can be increased, also adopts a common functional IP module in the FlexRIO FGPA cards, and ensures that the reusability of the technology and the maturity of products can be improved; and as the existing FlexRIO FGPA cards are adopted, when the aviation bus test card needs to be modified or upgraded, only the adapter part needs to be modified or upgraded, and thus a large improvement and promotion space can be achieved, the development of the products can be accelerated, and the difficulty of the development can be reduced.

Description

technical field [0001] The invention relates to the field of avionics test systems, in particular to an aviation bus test card based on FlexRIO. Background technique [0002] So far, the avionics system has gone through 4 generations of technology, which are discrete avionics system, combined avionics system, integrated avionics system, and advanced integrated avionics system. After more than 70 years of development, there are many types of aviation buses, and the communication protocols are becoming more and more complex. The same avionics equipment often contains a variety of avionics interfaces, and the coexistence of standard and non-standard interfaces puts forward higher requirements for the avionics test system. [0003] At present, the mainstream avionics test system uses standard and customized avionics test cards to build the avionics test system, which occupies many boards and has low reusable resources between test systems. Customized board technology involves ...

AI Technical Summary

Problems solved by technology

Customized board technology involves a wide range of areas and poor technology reusability, resulting in poor product maturity

If part of the design needs to be modified, the entire board needs to be redesigned, the technical flexibility is small, and it is not suitable for improvement
