摘要:
 1394B作为成熟的商用总线，具有传输速率高、传输距离远、传输介质丰富等特点，并支持物理闭合环拓扑，具有一定的冗余可靠性。 SAE AS5643在1394B总线的基础上，从实时性和确定性的角度出发，对1394B总线应用进行了一系列的扩展和约束，使1394B总线能够满足航空等领域的应用要求，但AS5643未能对传输效率和容错性进行详细的规定。文中研究和分析了AS5643标准定义的数据结构和传输特性，结合1394B总线协议的相关规定，提出了改进总线传输效率和容错性的措施。最后，利用FPGA逻辑和Link/PHY芯片实现了AS5643定义的CC/RN功能节点。经测试表明，文中提出的改进措施能够有效提高CC/RN功能节点的传输效率和容错性。
Abstract:
 As a commercial bus,1394B has the advantage of high speed,long transmission distance and abundant transmission medium. 1394B also supports physical loop-connection detection,so it has a certain redundant reliability. SAE AS5643 imposes a series of con-strains on 1394B considering real-time and determinism,to meet requirements of aerospace application. But transmission efficiency and fault tolerance are not discussed in detail. In this paper,research the analyze the data structure and transmission characteristics defined by AS5643,then bring forward measures to improve transmission efficiency and fault tolerance combined with the rules of 1394B. Finally, the implementation of CC/RN functional node with FPGA and Link/PHY chips is done. Tests show that these measures can improve transmission efficiency and fault tolerance of CC/RN.
