Problems solved by technology

[0004] But, because the data transmission standards of PCI Express bus and MVB bus are not the same, PCI Express bus can not be directly connected to MVB network, therefore, need badly a kind of data conversion device between MVB bus and PCIExpress bus

Abstract

The invention provides a gateway based on an MVB (multifunction vehicle bus) network. The gateway comprises an MVB network standard interface, an MVB protocol controller, a main processor, a PCI Express (peripheral component interconnect express) protocol controller and a PCI Express standard interface, wherein an MVB bus is connected with a PCI Express bus through the MVB network standard interface, the MVB protocol controller, the main processor, the PCI Express protocol controller and the PCI Express standard interface in sequence. By receiving the MVB data from the MVB network, the gateway based on the MVB network provided by the invention can convert the MVB data into PCI Express data and send the PCI Express data to the PCI Express bus. Besides, the gateway can also convert the PCI Express data from the PCI Express bus into the MVB data and send the MVB data to the MVB bus, thus technicians can test the MVB network through the PCI Express bus.

Description

technical field [0001] The invention relates to network data conversion technology, in particular to a gateway based on MVB network. Background technique [0002] Industrial fieldbus is a network communication standard, which enables devices from different manufacturers to communicate through the industrial fieldbus using a common communication protocol. Among them, the distributed control-based multifunction vehicle bus (Multifunction Vehicle Bus, MVB) is a serial data communication bus mainly used between interconnected devices that require interoperability and interchangeability, and has real-time Strong, high reliability and other advantages, it is the recommended solution for the international standard of Train Communication Network (TCN). However, due to the strong professionalism of the MVB bus, currently only a few manufacturers can provide related interface equipment for the MVB bus, and there are few related test instruments for the MVB bus, which makes it difficu...
