基于BU—61580与USB的MIL—STD—1553B总线控制卡的设计

摘要

MIL-STD-1553B bus is a military serial bus, with high reliability. This bus has a wide range of applications in aviation, aerospace, automotive and other fields. USB is a popular universal serial bus. The USB communication protocol allows the bus transferring data whit high rate, with versatility interface and other advantages. In order to testing the 1553B communication in the aircraft or other applications normal or not, a special 1553B Bus control card is need. An design named 1553B Bus Control Card is described which is based on the 1553B Bus and USB protocols. This control card can achieve the basic functions including reading and sending data, mode and broadcast messages. This control card can also inherit the advantages of USB, including supporting plug and play, high rate and programmable message structure. Then the implementation of this design, including the BU-61580 and USB connection and software methods are introducd. Finally, it describes the results of the control card.%MIL—STD—1553B总线是一种军用串行总线,具有完整的总线通信协议,具有很高的可靠性,在航空、航天、汽车电子等领域有广泛的应用.USB总线是一种常用的通用串行总线.USB完整的通信协议使得USB传输具有很高的传输速率,接口通用性强等优点.为了在地面测得飞机或者卫星等应用上的1553B总线通信是否正常,需要专门的总线控制卡来进行通信测试.介绍了一种基于BU—61580和USB芯片设计的1553总线控制卡,该控制卡实现1553B总线控制的基本功能,包括读取和发送数据,发送方式控制字,向总线广播数据等基本的总线消息.同时继承了USB的各种优点,即支持即插即用功能,传输速度高,支持可编程的消息控制模式.并且介绍了这种总线控制卡的实现方法,包括BU—61580与USB芯片的硬件连接和软件实现,最后介绍了控制卡的测试结果.
