光总线精确制导控制与测试系统具有技术难度大、系统性强、所处环境恶劣,电磁兼容性要求高的特点。要有效地保障系统预定任务的顺利执行和完成,提高战斗出勤率,因此,IEEE-1394b光总线系统必须是高可靠的、高稳定的。分析研究IEEE-1394b光总线拓扑的可靠性实验研究,是解决IEEE-1394b光总线系统可靠性问题的重要内容之一。提出了基于IEEE-1394b协议的光总线网络拓扑结构的可靠性研究方案,建立了环状拓扑可靠性分析模型,并给出了示例分析。实验结果表明,这种环状拓扑结构具有高的可靠性。
The accuracy guidance weapon's control and test system with optical bus has the character of technical difficulties,i.e.its systemic strong,working in a poor environment and demand of high electromagnetic compatibility.To effectively protect the system which is scheduled for the implementation and completion of tasks smoothly and to improve the fighting attendance,therefore,IEEE-1394b optical bus system must be high reliability and high-stability.The reliability analysis of IEEE-1394b optical bus topology is an important part to solve the problem of the reliability of IEEE-1394b optical bus system.This paper presents the reliability of research programs of network topology based on IEEE-1394b protocol optical bus,establishes the reliability analysis model for ring topology and gives a study case.The experimental results show that the ring topology has high reliability.
