Locomotive reconnection gateway based on Ethernet (ETH)

The invention provides a locomotive reconnection gateway based on Ethernet (ETH). The locomotive reconnection gateway comprises a first UIC (International Union of Railways) gateway module and a first ETH/MVB (Multifunction Vehicle Bus) conversion module, wherein the first UIC gateway module is electrically connected with the first ETH/MVB conversion module; the first UIC gateway module is used for receiving first WTB data transmitted by a first locomotive through a wired train bus (WTB); the first WTB data are converted into first MVB data, and the first MVB data is transmitted to the first ETH/MVB conversion module; the first ETH/MVB conversion module is used for converting the received first MVB data into first ETH data, and transmitting the first ETH data to a second locomotive through an ETH bus. According to the embodiment of the invention, the problem that a WTB reconnection mechanism locomotive cannot be reconnected to an ETH reconnection mechanism locomotive in the prior art is solved.
