Abstract

The invention belongs to the technical field of avionics, and specifically relates to an FPGA-based ARINC818 bus analysis and test apparatus; the analysis and test apparatus is mainly applied to an avionics digital video transmission system and capable of realizing simulation testing and debugging analysis on ARINC818 bus equipment. Compared with the prior art, the FPGA-based ARINC818 bus analysis and test apparatus has the following advantages: (1) the FPGA-based ARINC818 bus analysis and test apparatus can output FC (fiber channel) video stream meeting the ARINC818 standard according to an interface control protocol,and the FC video stream is used as a test source of ARINC818 bus receiving products; (2) the FPGA-based ARINC818 bus analysis and test apparatus can receive and store the ARINC818 video stream in the FC for realizing protocol conformity analysis on video transmission products of the ARINC818 bus interface; and (3) the FPGA-based ARINC818 bus analysis and test apparatus can realize the substantialization of main logics through protocol processing by the field-programmable gate array (FPGA). Therefore, the FPGA-based ARINC818 bus analysis and test apparatus has the characteristics of simple hardware, high integration level, low cost, high expandability and the like.

Description

technical field [0001] The invention belongs to the technical field of avionics, and specifically relates to an FPGA-based ARINC818 bus analysis and testing device, which is mainly used in aviation digital video transmission systems, and can realize simulation testing and debugging analysis of ARINC818 bus equipment. Background technique [0002] ARINC818, as a new generation of Avionics Digital Video Bus (ADVB) standard, is formulated based on the FC-AV (FibreChannel-AudioVideo) protocol, which can be mapped to Fiber Channel, and inherits the high resolution, high reliability, and low delay of the FC-AV protocol It has the advantages of strong anti-electromagnetic interference performance, etc., and meets the transmission requirements of high-speed real-time uncompressed video in aviation systems. [0003] At present, domestic equipment supporting the ARINC818 standard lacks supporting solutions such as simulation testing, debugging analysis, and maintenance support, and ca...
