摘　　要：本文开发了CAN总线测控系统的上位机节点的驱动程序,该驱动程序有两个接口:与USBCAN卡交换信息的动态链接库接口及与其它监控软件相互交换信息的OPC接口。通过调用USNCAN卡动态链接库函数与CAN网络通信。基于自定义协议Prot-Can,实现了上位机与下位机的通信。另外设计了CAN测控网络的人机界面,实现了网络配置及网络数据的管理。The master node driver with two interfaces has been designed. It can exchange data with USBCAN interface card and other application software. It also transfers DLL of USBCAN card to realize the connection with the CAN network. The communication software between master and slave is developed based on user-defined protocol Proto-Can through the driver software. Consequently, it further verifies the man-machine interface of the network, the advancement and practicability of the network in practice.
