摘　　要：基于CAN总线物理层和数据链路层设计了一个实时令牌传输网络。该网络具有令牌网传输实时性的优点,克服了以太网延时的不确定性。同时又利用CAN总线的仲裁特性,实现了网络的初始化和重构算法。经实际测试证明,本设计能够可靠地实现站点之间的数据传输,实现了网络传输的目标。This paper describes a design of real time token network based on phsical layer and data link layer of CAN bus. The network has real time transmission of token network and overcomes uncertainty of Ethernet. Meanwhile, it takes advantage of arbitration of CAN bus and achives initialization and reconfiguration algorithm of network. This design can realize data transmission between stations stably and meet the goal of network transmission after actual test.
