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.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 1553B 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.
