Design of Space Payload Test Information System Based on FC-1394

IEEE1394 is a high-speed serial data bus with support for isochronous transmission and asynchronous transmission.It is currently well used in data transmission of spacecraft payload test,however,there are still some problems such as large power consumption,large transmission distance and limited speed in the future application of large-scale spacecraft load test information transmission.As a good compatibility,high reliability,low latency,long transmission distance and high transmission rate advantages of advanced bus technology,fiber channel could provide the upper protocol a generic high-speed data transmission channel.Based on the basic characteristics of IEEE1394 and fiber channel,this paper presents a FC-1394 bridge scheme for space payload test information system,and provides a solution for data network interconnection based on IEEE1394 and fiber channel protocol mapping space information system.
