Description

technical field [0001] The invention belongs to the application field of space technology, and in particular relates to a multi-protocol interface data acquisition device and acquisition method based on a SpaceFibre interface. Background technique [0002] SpaceFibre is a high-speed, full-duplex aerospace serial bus whose transmission rate can reach 2Gbps to 40Gbps, supports multi-node data transmission, has high bandwidth, low delay, high reliability, low bit error rate and strong Deterministic and other performance, support virtual channel and QOS (Quality of Service) data scheduling mechanism. [0003] The communication protocol refers to the rules and agreements that must be followed by the communication devices of both parties to complete the communication or service. If there is no unified communication protocol between communication devices, information transmission cannot be carried out. [0004] Protocol conversion refers to the information processing work to real...
