摘　　要：在航电系统中,1553B总线作为主干网络被广泛应用。多种航空子设备通过1553B总线进行交联,当系统一旦出现问题,复杂的交联关系使得故障难以定位与排除,系统设计中迫切需要一种总线监控器对1553B总线消息进行采集和记录,进行数据监控和故障定位。因此,文中提出了一种基于链表控制的1553B总线监控器IP的设计与实现,并将其成功集成在So C芯片中进行了硅验证。测试结果表明,该总线监控器满足MIL-STD-1553B标准中1553B总线规定的BM全部功能,且具有监控效率高,运行稳定可靠,对子系统主机依赖小等特点,可对1553B总线上传输的信息进行有效监控,在总线系统维护维修中发挥重要的作用。1553B Bus has been widely used in aviation system as main net. A varity of aviation electronic devices communicate with each other though 1553B. However the complicated connection among devices makes the fault difficult to locate and eliminate. In system de-sign,urgently need a bus monitoring for sampling and recording of message for 1553B,complishing the data monitoring and fault loca-ting. The design and realization on bus monitor IP of 1553B Bus based on command block chain is proposed. Then implement it into SoC to be verified. The verification results demonstrate that this bus monitoring function can completely satisfy MIL-STD-1553B Standard and even have more efficiency,better stabilization and less independence on system host etc. ,which can effectively monitor the message in 1553B Bus. This bus monitoring function will play an important roles in monitoring.
