The invention provides a device and system for making a multifunctional vehicle bus MVB network card and a peripheral component interconnection PCI bus interface communicated. The device can be achieved by the adoption of a field-programmable gate array, and comprises a PCI interface module, a PCI bus analysis module and a PC104 interface module which are sequentially in communication connection. The PCI interface module is used for being connected with the PCI bus interface; the PC104 interface module is used for being connected with a PC104 bus interface of the MVB network card; the PCI bus analysis module is used for converting PCT protocol data from the PCI interface module into PC104 protocol data, sending the PC104 protocol data to the PC104 interface module, converting the PC104 protocol data from the PC104 interface module into the PCI protocol data and sending the PCI protocol data to the PCI interface module.
Description
technical field [0001] The embodiment of the present invention relates to electronic technology, and in particular to a device for communicating with a multifunctional vehicle bus MVB network card and an external component interconnection PCI bus interface. Background technique [0002] In order to realize the communication between the multifunction vehicle bus (Multifunction Vehicle Bus, MVB) communication network card and various functional components of the computer, the MVB communication network card based on the PC104 bus technology and conforming to IEC-61375 has been widely used in the rail transit industry. [0003] With the continuous advancement of science and technology, the peripheral component interconnect (Peripheral Component Interconnect, PCI) bus is gradually replacing the PC / 104 bus technology. Compared with the PC / 104 bus technology, the PCI bus has more advantages in cost control when the communication rate is not high. Therefore, compared with the MVB n...
