Problems solved by technology

At present, the old spacecraft mainly use the traditional MIL-STD-1553B bus. Although the MIL-STD-1553B bus has the characteristics of high reliability and high real-time performance, it cannot fully meet the requirements of future spacecraft due to the limitation of its 1Mbps transmission bandwidth. The requirements of various technical indicators

Description

technical field [0001] The invention relates to the technical field of high-speed serial bus communication and testing, in particular to an FC-AE-1553 simulation communication demonstration system and a data sending method. Background technique [0002] The formulation of FC (Fibre Channel Fiber Channel Protocol) began in 1988, and was in charge of the ANSI X3T11 group of the American National Standards Committee. At present, a huge protocol family has been formed, and it is constantly being updated and improved. In recent years, my country has also begun to vigorously study the high-speed interconnection technology related to the FC protocol, and successively released a series of "GJB6410-2008 Fiber Channel Physical and Signal Interface FC-PH", "GJB6411-2008 Fiber Channel Avionics Environment FC-AE" and so on. The FC protocol standard has been widely used in various types of aerospace vehicle internal electronic communication network systems. [0003] The FC protocol netwo...
