摘要
FlexRay总线相比于CAN总线具有高传输速率、高可靠性等优点,是一种正在快速发展的现场总线。目前武器系统控制中使用较为广泛的仍然是CAN总线,因此解决CAN总线与FlexRay总线之间的数据交互问题可以提高火控系统的信息传输速率。该文以MC9S12XF512微处理器作为核心提出了FlexRay-CAN网关的设计思路,对FlexRay的数据帧进行拆分重组,使其满足CAN协议的数据帧格式,实现两种不同总线之间的数据传输。分析表明FlexRay-CAN网关的实现适用于火炮发射系统,数据传输可靠性得到明显提升。
Compared with CAN bus,FlexRay bus has the advantages of high transmission rate and high reliability.It is a rapidly developing field bus.Currently,CAN bus is still widely used in weapon system control,so solving the problem of data interaction between CAN bus and FlexRay bus can improve the information transmission rate of fire control system.In this paper,with MC9S12XF512 microprocessor as the core,the design idea of Flexray-CAN gateway is proposed.The data frame of FlexRay is split and recombined to meet the data frame format of CAN protocol,and the data transmission between two different buses is realized.The analysis shows that the implementation of FlexrayCAN gateway is suitable for artillery firing system,and the reliability of data transmission is obviously improved.
