Remote train network communication interface test gateway device and system

The invention provides a remote train network communication interface test gateway device and system, and relates to the field of train testing. The remote train network communication interface test gateway device comprises a service terminal composed of a protocol conversion module, a protocol environment configuration module, a management module and a test module; the protocol conversion management module cooperates with a communication device to establish a remote data transmission channel, the protocol environment configuration module cooperates with a subsystem to establish a consistencytest environment, and the management module records, traces and manages the operation data of the test module. A test platform is constructed, remote train network communication interface test services are supported, industrial network data can be converted into public network data, many-to-many interface test is supported, and the test efficiency is improved, the requirements of unified recording, management and tracing
