【摘要】 目前固体发动机试验已开始采用MIL-STD-1553B总线控制技术,由于固体发动机的工作过程具有工作时间短、过程不可逆等特点,因此一般地面试验采用冗余测控方式,而1553B总线协议标准规定,1553B总线上只能有一个总线控制器在线工作,因此总线控制器的冗余控制成为一个突出问题。针对该问题设计一种混合网络结构的1553B总线控制系统,通过实时数据诊断总线控制器故障,停止故障控制器,启动备用控制器完成后续的总线控制任务,实现了1553B总线控制器在线冗余控制功能。更多还原

【Abstract】 Now MIL-STD-1553B Bus control technology is apply in Solid Rocket test,because the working process has characteristic of short time and irreversible,so the mode of redundancy measure-control is always applied.But MIL-STD-1553 communication protocol defined that Bus Control is working only one,so it is a problem that the Bus Controller can be redundancy controlled.This paper designs a 1553B Bus Control System of Hybridnetwork struct,diagnosising fault by real time data,stopping the fault Bus Controller,trigging the Backup Controller to finish remainder working of Bus control,achieve the way of redundancy control on 1553B Bus.更多还原
