用于网络控制实验系统的CAN通讯卡的设计

Design for the CAN Communication Card on a Net-Controlling Experiment System

控制器局域网,简称CAN总线80年代初出现于汽车工业。由于有非常优异的总线共享和仲裁性能,能够快速,强有力地交换信息,具备故障界定隔离能力等特点。CAN总线在工业自动化、建筑物环境控制、机床、医疗设备等领域得到了较广泛的应用。本文根据小功率数字随动实验系统的特点与要求,给出了一种CAN通讯卡的硬件和软件设计。

Controller Area Bus,briefly CAN, first came into being in automobile industry in 1980s. Due to its extraordinary bus-sharing and arbitration ability, which make it possible for quick exchange of information and isolation of malfunctions. CAN Bus has been widely applied in the fields of industry-automation, architectural environment controlling , mechanics, medical facility and so on. This paper demonstrates both hardware and software design for a kind or CAN communication card according to the features and requirements of low-power digital systems.
