面向星载应用的地面测试系统设计CSCD

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。

The Ground Test System Designed for Space-Borne Application

Inter-satellite data transmission system requires space-borne equipment with real-time da- ta transmission, high accuracy, and the data transfer process must remain beat sync. Space-bome equip- ment 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 de- velopment 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 transmis- sion mode with 1553B bus, such as BC-RT （Bus Controller-Remote Terminal）, RT-BC （Remote Termi- nal-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 ments, but also can be regard as a general platform for the el test method with 1553B bus. requirements for related space-borne equip- data stream testing and thus provides data lev-
