Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] One of the core ideas of the present invention is to decode and check the received network data for the characteristics of the main network communication protocols (MVB and HDLC) adopted in the TCN network, and then cache the received network data, and then read the data from the cache area Take the decoded data, add the check code, encode and send according to the characteristics of the converted network communication protocol, so as to realize the interconnection and intercommunication between network elements of different network protocols in the TCN network at the data link layer.

[0034] refer to figure 1 , showing the flow of an embodiment of the vehicle communication network data conversion method of the present inv...

Abstract

The invention provides a conversion gateway and conversion method of vehicle communication network data. The vehicle communication network data comprises first communication protocol data and second communication protocol data of a data link layer. The conversion method of the vehicle communication network data comprises the following steps of: decoding the received first communication protocol data, and writing the first communication protocol data into a data buffer area; and reading the decoded data from the data buffer area, coding the data according to the requirements of the second communication protocol, and then, sending the data. By decoding one kind of communication protocol data and then coding the communication protocol data into another kind of communication protocol data, the invention can realize interconnection and intercommunication among network elements with different communication protocols.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a vehicle communication network data conversion gateway and a conversion method thereof. Background technique [0002] Multifunctional Vehicle Bus (MVB, Multifunctional Vehicle Bus) is a vehicle bus that connects standard equipment located in the same vehicle, or in different vehicles that are fixed and reconnected, to the train communication network. MVB adopts a master-slave mode, and the access to the medium is centrally controlled by the only master device on the bus. The master device divides the bandwidth of the bus into two parts, that is, the part allocated periodically (periodic phase) and the part allocated on demand (occasional phase). Process data is transmitted periodically, and message data is transmitted sporadically. Devices in MVB can be divided into 6 types according to their functions, from 0 to 5. Among them, Class 0 devices do not have data c...
