基于BU-61580透明模式的总线监控器功能实现

Function Implement of Bus Monitor Based on Transparent Mode of BU-61580

  • 摘要: 针对基于BU-61580缓冲模式实现1553B总线监控器功能的方式,存在资源消耗多、内存空间小等问题,设计研发了基于BU-61580透明模式的外部接口电路和总线传输协议.该系统在一片FPGA控制下实现总线控制器和远程终端两部分功能,同时借助FPGA的RAM资源将缓冲区RAM的大小扩展到最大64 K字.大量试验表明,总线控制器在不同环境下监听的消息数据准确无误,该系统稳定可靠.

     

    Abstract: This paper introduces an external interface circuit and bus transmission protocol of BU-61580 transparent mode.The purpose is to solve the problems of resource consumption and small memory space in the design of 1553 B bus monitor function based on BU-61580 buffer mode. Experiments prove that the message data monitored by the bus controller is accurate in different environments.The system is stable and reliable. A large number of tests have shown that the message data monitored by the bus controller in different environments is accurate with no error, the system is stable and reliable.
