MVB (multifunction vehicle bus) communication testing method for train equipment

The invention discloses an MVB (multifunction vehicle bus) communication testing method for train equipment. The MVB communication testing method includes steps of installing testing software in the equipment to be tested and auxiliary software in auxiliary testing equipment and storing corresponding port configuration files; controlling a plurality of source ports of the equipment to be tested to output transmission data in a certain format by the testing software; controlling destination ports of the auxiliary testing equipment corresponding to the source ports of the equipment to be tested by the auxiliary testing software so as to receive the transmission data outputted by the equipment to be tested and forwarding the transmission data to the equipment to be tested via the corresponding source ports of the auxiliary testing equipment; controlling destination ports of the equipment to be tested corresponding the source ports of the same to receive the forwarded transmission data of the auxiliary testing equipment and displaying the forwarded transmission data and the transmission data outputted by the equipment to be tested by the aid of the testing software. By the MVB communication testing method, port coverage rate of the MVB communication testing of the equipment to be tested can be increased, testing information of the MVB communication of the equipment to be tested can be added, and automation during testing is improved.
