基于FPGA的星载高速数据复接器的复接模块设计

Design of multiplex module for onboard high-speed data multiplexer based on FPGA

随着空间科学技术的发展,载荷数据种类和数据传输速率不断提高与数据处理传输能力不足之间的矛盾日益凸显,为了解决这一问题,设计了一种基于CCSDS AOS协议的星载数据复接器设计方案.该设计方案能够通过LVDS接口接收实时遥测数据,回放数据,以及1553B总线数据,通过RS422接口接收工程遥测数据,话音数据,并将以上各路数据复接组帧加扰下行.

With the development of space science and technology,the contradiction between the increasing load data type and data transmission rate and the insufficient data processing and transmission capacity has become increasingly prominent. In order to solve this problem,a kind of onboard data multiplexing based on CCSDS AOS protocol is designed. The design scheme can receive real-time telemetry data,playback data through the LVDS interface,and 1553 B bus data,receive engineering telemetry data and voice data through the RS422 interface. And multiplex the above data,framing, scrambling, and then downlink.
