Avionics system low-delay bus test verification platform

Abstract

The invention relates to an avionics system low-delay bus test verification platform, and belongs to the technical field of aerospace bus testing, the avionics system low-delay bus test verification platform comprises a shell, a plurality of aviation connector digital test function boards arranged in the shell and a test bottom plate connecting seat, and the test bottom plate connecting seat is used for installing the aviation connector digital test function boards; the test bottom plate connecting seat comprises a first mounting rack and a second mounting rack which are used for mounting an aviation connector digital test function plate, the first mounting rack and the second mounting rack are sequentially arranged in the vertical direction, and locking assemblies are arranged on the first mounting rack and the second mounting rack. The locking assembly is used for fixing the aviation connector digital test function board. The test base plate connecting seat is arranged to be of a double-layer structure, and the aviation connector digital test function board is fixed on the test base plate connecting seat, so that space is effectively saved, and miniaturization of the avionics system low-delay bus test verification platform is facilitated.

Description

technical field [0001] The present application relates to the technical field of aerospace bus testing, in particular to a low-latency bus testing verification platform for avionics systems. Background technique [0002] The airborne avionics system mainly includes communication, navigation, display, cockpit entertainment and other equipment, which is used to complete the communication, navigation, information processing and control between the aircraft and the ground. It is the core and most important equipment of the aircraft and can directly affect the advanced degree and comprehensive ability. [0003] Among them, the low-latency bus test and verification environment is mainly a test and research platform supporting the system bus in the avionics system, which can provide low-latency data simulation sources, has network test functions, and realizes a simulation environment based on low-latency bus functions. By installing a special type of aviation connector digital tes...
