双冗余CAN总线适配卡设计与实现

Design and Realization of A Redundancy CAN Bus Adapter Card

控制器局域网CAN(Controller Area Network)是一种多主方式的串行通信总线,满足控制系统及其它较高数据要求系统的需求。因其应用的恶劣环境,讨论CAN硬件实现方法及软件管理流程。设计了双冗余总线结构,以提高CAN总线的稳定性与可靠性。

CAN（ Controller Area Network）bus is a serial communication bus with mutli - point controllable style. It enhances data＇s safety to fit control system and other needing high data safety system area. Because of its bad environment, we discuss those realizing methods of bardware and software management and design a redundancy CAN bus structure so as to improve its stability and reliability.
