摘要:

针对RS-422接口与1553B总线接口无法直接进行高可靠性数据通信,提出了一种基于BU-61580总线控制器的接口及容错设计。设计采用1553B接口芯片BU-61580,通过FPGA控制完成了RS-422与1553B的接口控制及二者之间的数据处理。在硬件接口设计的基础上,设计IP-CORE完成BU-61580的芯片配置,并通过增加容错设计提高了总线控制器数据通的可靠性。经测试结果显示,计算机通过总线控制器与RT终端通信稳定、可靠,并应用于某测试系统中。

Abstract:

For the case RS-422 interface can not directly communicate with 1553B bus interface with high reliability, a interface and fault-tolerant design based on BU-61580 bus controller is proposed . The design uses 1553B interface chip BU-61580 that complets interface control and data processing between RS-422 and 1553B by FPGA control. On the basis of the design of the hardware interface, it completes BU-61580 chip configuration by designing IP-CORE, and improves the reliability of data communication of bus controller increasing the fault-tolerant design.The test results show that communication is controller and stable with bus controller and RT terminal,and it is used in a test system.
