| 摘 要： | 军用车辆中主要使用1553B,CAN及实时以太网数据总线.MIL STD 1553B总线由命令字、数据字和状态字组成,传输有半双工、传榆协议和系统控制等方式,采用双冗余故障容错,其第二条总线处于热备份.CAN总线应用带优先权的非破坏性的总线访问法,每帧最多发送8bet数据,每节点都定义唯一标识符,各节点上的总线控制器根据节点与报文标识符间逻辑关系接收或不接受总线上报文.以太网总线则具有更好的总线拓扑结构.

| Abstract: | 1553B bus, CAN bus and Ethernet bus is used in military vehicle. MIL_STD_1553B bus is composed of command word, data word and status word, semiduplex transport, transport protocol, and system control modes were applied for transmission, and dual redundant fault tolerance was used and second bus was in warm back-up. Nondestructive bus access method for band priority was applied in CAN bus, 8bet data was sent in every frame, and only identifier was defined for each node. The message on bus is received or does not by bus controller on each node according to the node and the logical relation between message identifiers. |

| Keywords: | 1553B bus CAN bus Ethernet bus Military vehicle |
