1553B总线控制器双机热备份设计

1553B总线作为一种高可靠的总线技术,广泛应用运用于军事领域。由于1553B总线双冗余备份的只是总线传输通道,而总线上的控制器没有热备份,一旦总线控制器出现故障,则整个总线将瘫痪。主要论述一种利用软件实现总线控制器的双机热备份设计思想和方法,此方法易于实现,效率很高,并有效地防止了工作BC和备用BC的误切换,实践验证,这种设计切实可行,有一定的通用性。

Design on Dual-module Redundance of 1553B Bus Controller

1553B bus as a high reliable bus technology has been widely used in the military field.The whole bus would be paralyzed if the bus controller does not have a backup and the bus controller fails because the dual redundance of 1553B bus is just a redundant bus transmission channel.The design ideology and method to implement the dual-module redundance of bus controller by means of a software are discussed.This method is easy to implement and is efficient,can prevent the incorrect transfer between misuse BC and...
