| Abstract: | This paper studies the data conversion system between CAN bus and PCI bus,and introduces the hardware circuitry and logic programming systems.FPGA and PCI interface chip PCI9054 and microprocessor are used to realize fast communication between large amounts of data industrial field bus CAN nodes and the host computer.The designed PCI_CAN data conversion system gives a maximum data transfer rate of 1 Mbit·s-1 and a communication distance greater than 10 km,meeting the performance requirements of the CAN bus.The FPGA+PCI9054 design offers easy system upgrade and migration,and comparability with a variety of different types of computers without PCI not found errors or blue screens. |
