摘要
建立基于CAN总线的实时数据采集系统,开发出虚拟设备驱动程序VxD,利用VxD读出数据总线上的数据,存入缓冲区内,采用事件驱动的方式,实现CAN总线与应用层之间的数据通讯,完成高速、实时数据采集。
A high-speed data collection sytem based on PCI bus in Windows is established and a virtual device driver program is developed. Data are read out through VxD, and are stored in the buffer. Through the event driving mode, it delivers the data from the bottom hardware to the program, and the realtime high-speed collection is realized.
