基于ARM9的1553B与CAN总线转换卡的设计与实现

Design and Realization of CAN Bus Transition Card and 1553B Based on ARM9

在某些军用测控系统中,经常存在1553B总线与CAN总线之间的总线转换,这就促使了1553B与CAN总线转换卡的诞生。本文1553B与CAN总线转换卡采用ARM9处理器作为中间转换平台,RTLinux操作系统作为调度,通过上层应用程序实现了1553B总线与CAN总线之间的信息转换。转换卡还通过扩展的LCD接口和串口,实现了转换数据的实时监控。该系统在实际应用中得到了实时性,可靠性等方面的验证。

In some military measurement ＆ control system there always exist bus transition between the 1553B bus and CAN bus. This transition boost the design and realization of 1553B and CAN bus transition card. The 1553B and CAN bus transition card take ARM9 processor as the transition platform,RTLinux operation system as the scheduler and achieved the information transition between 1553B bus and CAN bus through the top layer application program. The transition card also achieved the real - time monitor and control of transform data through the extended LCD interface and serial interface and vali- dated its real - time ability and reliability by the application.
