Abstract

The invention relates to the technical field of train communication network control and particularly relates to an MVB class 4 device network card based on an FPGA and an ARM. The MVB class 4 device network card comprises an MVB network controller used for realizing the process data and message data functions of a physical layer and a link layer and configuration and management functions of the network card and upwardly providing a link layer software interface which is specified by a TCN network standard IEC61375-1, and an RTP protocol stack system used for realizing the monitoring data, process data and message data functions of a network layer, a transmission layer, a conversation layer, an expression layer and an application layer and upwardly providing an application layer software interface which is specified by the TCN network standard IEC61375-1. Through the mutual cooperation of the MVB network controller and the RTP protocol stack system, the process data, message data, user configurable and bus management functions and performance which are specified by IEC61375 are realized, and thus a situation that a core device depends on foreign procurement is eliminated.

Description

technical field [0001] The invention relates to the technical field of train communication network control, in particular to an MVB (Multifunction Vehicle Bus, Multifunction Vehicle Bus) based on FPGA (Field Programmable Gate Array, ie Field Programmable Gate Array) and ARM (Advanced RISC Machines, ARM processor chip for short). Function vehicle bus) network four types of equipment network card. Background technique [0002] Network control technology is the mainstream and trend of current rail transit equipment communication control technology. In foreign countries, especially some developed countries in Europe, solutions based on network control technology have been widely used in the fields of subway, high-speed rail and urban rail transit vehicles that require high real-time and reliability. TCN (Train Communication Network, train communication network) is a mainstream train field bus network, the network is a two-layer bus structure, including the MVB network connectin...
