A intelligent CAN Card scheme with PCI interface with the FPGA and MCU frame as control core,CAN bus as communication bus is proposed,The CAN card is mainly used to provide the real-time solution of servo control system,this card exchange data through PCI bus interface with industrial personal computer and communicate with the remote data acquisition module through CAN bus,this card can make full use data processing ability of the PC machine and control ability of intelligent CAN card.The hardware circuit design of intelligent CAN card, SPI logic circuit design and the design of CAN node are focused on. This method has broad application prospect with highly real-time performance and well reliability.
