为了满足姿轨控/推进仿真中心计算机与通用仿真接口箱之间的高速实时数据传输,设计了一套基于IEEE1394串行总线的通用数据传输设备,同时介绍了IEEE1394协议的传输类型以及物理层、链路层、事务层和总线管理层的功能,并详细描述了基于高性能的1394控制器TSB12LV01B和TSB41AB1的传输系统的硬件设计、软件设计和工作过程。经测试方案实验验证,该设备可以实现最高400Mb/s的高速数据实时传输,证明了这种系统的可行性和可靠性,对其他通信系统的设计具有参考价值。

To achieve the high-speed performance of real-time data transmission between the universal simulation interface box and the computer of the attitude and orbit control ＆ propulsion ground simulation system, a high-speed data transfer system based on IEEE1394 bus is designed. The principle of 1394 bus, the transmis- sion types of IEEE1394 protocol, the function of the physical layer, the link layer, the transaction layer and the bus management layer are also introduced. A kind of transfer system implementation based on the high performance 1394 controllers TSB12LV01B and TSB41AB1 is described in detail, including the hardware design, software design and principle. The test experiment results show that the 1394 transfer equipment can obtain a maximum bus speed of 400 Mb/s. This proves that the design of high-speed real-time data transmission system is feasible and realizable. This design has certain reference value to other similar communication research.
