摘要： 星间数据传输体制要求星载设备数据传输具备实时性、高精确性，在数据传输过程中必须保持节拍同步。相关星载设备在上天前要进行严格的数据流测试以保证满足要求，因此在地面搭建数据流测试系统有重大的意义。本文通过对1553B总线仿真卡进行二次开发，完成了地面测试系统的设计。对相关星载设备的测试结果表明，该系统实现了1553B总线中的BC-RT（总线-远程终端）、RT-BC（远程终端-总线控制器）、RT-RT、MT（监视终端）传输模式，完成了限定时间内规定数据量的正确传输，保证了数据传输节拍的同步，确保了对相关星载设备的数据流测试。该系统不仅能够满足相关星载设备的测试需求，而且可以作为一种通用的数据流测试平台，较好地提供了1553B总线数据级的测试手段。

Abstract: Inter-satellite data transmission system requires space-borne equipment with real-time data transmission, high accuracy, and the data transfer process must remain beat sync.Space-borne equipment related must conduct rigorous pre-launch data stream tests to ensure meet the requirements, so building data stream test system on the ground has great significance.This paper makes the secondary development based on 1553B bus simulation card and completes the design of ground testing system. The test results for related space-borne equipment show that this system has realized several kinds of transmission mode with 1553B bus, such as BC-RT (Bus Controller-Remote Terminal), RT-BC (Remote Terminal-Bus Controller), RT-RT, MT (Monitoring Terminal), and completed the transmitting procedure with given amount of data during the limited period. In a word, the system designed in this paper satisfies the tempo synchronous for data transmission and completes the data stream testing for the relevant space-borne equipment. The system can not only meet the test requirements for related space-borne equipments, but also can be regard as a general platform for the data stream testing and thus provides data level test method with 1553B bus.

Key words: +Space-borne equipments, Bus Controller, Remote Terminal, +Monitoring Terminal
