摘要
随着MIL-STD-1553B总线的广泛应用,机载数据总线系统的拓扑结构越来越复杂;为了提高总线传输的可靠性,机载数据总线普遍采用双余度形式和不可分割连接形式,因此总线的维护检测也显得越来越重要;归纳了机载双余度1553B总线的工作状态及其相互之间的关系,给出了总线故障的概念,详细分析了总线系统架构中3个不同阶段的检测方法以及应用场合、检测内容和拓扑结构,最后提出了机载1553B总线的可分割连接形式,以便于维护阶段的线路检测。
The topology of airborne data bus system is more complex with the wide application of MIL-STD-1553B data bus,and airborne data bus commonly used the form of dual-redundant and integral connection in order to improve the reliability of data transition,as the maintenance and testing of data bus is becoming increasingly important.Work status of the airborne dual-redundant data bus of 1553B and their mutual relationship are summarized,and the concept of fault of 1553B data bus is given,and the testing methods of 1553B data bus and their application situation and test content and topology on three different stages are analyzed in details,divisible connection form of airborne 1553B data bus is concluded to help line testing on the phase of maintenance.
