首先对CAN总线通讯协议进行分析,然后对嵌入式硬件仿真环境SkyEye的结构进行详细的研究,利用SkyEye构建了CAN总线通讯仿真环境.为了评估所设计的CAN仿真节点的性能,对CAN节点进行了仿真实验.仿真实验表明,我们所设计的CAN节点不仅能正确实现节点间的数据通信,还能达到较高的CAN网络通信速率.最后阐述了在计算机实践课教学中的应用.
The CAN bus communication protocol is analyzed at first in this paper. The structure of embedded hardware simulation environment SkyEye is discussed in detail. The CAN bus communication simulation environment is constructed using SkyEye. Simulation and analysis of CAN node is conducted in order to assess the performance of the CAN simulation nodes. Simulation results show that the designed CAN nodes not only communicate with each other well but also achieve a high CAN network communication rate. The application in computer practice teaching is elaborated at last.
