Vehicle communication network data conversion gateway

The utility model provides a vehicle communication network data conversion gateway, which comprises a first communication protocol conversion module, an interface control module and a second communication protocol conversion module, wherein the first communication protocol conversion module is used for decoding received data, then submitting the decoded data to the interface control module and requesting the interface control module to send out the data after reading the decoded data and encoding the data; the second communication protocol conversion module is used for decoding received data, then submitting the decoded data to the interface control module and requesting the interface control module to send out the data after reading the decoded data and encoding the data; and the interface control module is used for receiving the decoded data submitted by the conversion modules, writing the data into a data cache region in a first-in first-out mode and reading the decoded data from the data cache region in a first-in first-out mode according to the requests of the conversion modules. The utility model can realize interconnection between network elements with different communication protocols by decoding one type of communication protocol data and then encoding the type of communication protocol data into another type of communication protocol data.
