摘要
机载公共设备综合管理系统(UMS)是一个分布式容错计算机网络系统,具有余度、重构、故障容错及扩充功能,综合化是其发展方向。这些技术特点要求UMS系统的内部数据总线网络具有容错能力、高可靠性及高传输速率等网络性能。基于SAE AS5643协议1394B总线在多余度配置、带宽、时间确定性和可靠性方面有优势,广泛应用在军用航空领域。文中介绍了IEEE1394B总线技术,机载UMS系统体系结构,并简要阐述了应用于UMS系统的二余度1394B总线网络容错设计、通信节点硬件设计以及通信软件设计等关键技术。最后通过UMS系统综合验证,结果充分表明该二余度1394B总线网络功能完备,性能良好。
The Airborne UMS is fault-tolerant computer network system with the function of redundancy,reconfiguration,fault-tolerance and extendability. Its integration is an developing trend. These characteristics require the internal data bus network of UM S is provided with ability of fault-tolerant,high-reliability,high transfer-rate. The 1394 b bus based on SAE AS5463 protocol has the advantage of redundant configuration,high-bandw idth,definiteness,high-reliability,which is widely used in the field of military aviations. In this paper,present the bus technique of IEEE1394,then introduce system structure of the Airborne UM S,and elaborate the critical technologies used for dual-redundancy 1394 B bus network and the design of node hardware and software. The design of dual-redundancy 1394 B bus network passes the integration verification of the UM S. The experimental results fully demonstrate that it has complete equipments and good performances.
