针对高带宽、低延迟、高可靠的军用需求,及针对要求具有较高的实时性、确定性、可靠性的飞行控制系统,对IEEE-1394b和AS5643的协议结构进行了研究,研发了Mil-1394b总线接口板。详细叙述了板卡的功能、硬件板卡的原理及实现、软件实现,进行了大量的仿真、调试和分析。该板卡达到了较高的传输速率,性能良好,满足设计需求,已应用于某些飞行控制系统中。
For the high bandwidth, low delay and high reliability of military requirements, and for the requirements of the flight control system with high real-time, certainty and reliability of the protocol structure of the IEEE-1394b and AS5643 were studied, developed Mil- 1394b bus interface board. Described in detail the function of the board, the principle and implementation of the hardware board, software implementation, a lot of simulation, debugging and analysis. The board achieved a higher transmission rate, good performance, to meet the design requirements, has been used in some flight control system.
