Remote input-output unit based on MVB network

The utility model relates to an MVB network-based remote input and output unit (RIOM), which comprises a power supply module, a protocol conversion BMVB module, a data transfer module, as well as a signal input and output module connected with the protocol conversion BMVB module through the data transfer module; wherein, the protocol conversion BMVB module is provided with an MVB network bus interface which is connected with the MVB network bus; and the signal input and output module is connected with an electrical system of the train compartments. By providing a remote input and output unit (RIOM) which is connected with the MVB network bus and can realize various functions, the utility model fills the gap in China, realizes the acquisition of a large number of analog and digital amounts and achieves the functions of network control and the like. The utility model provides a basic network platform for the future domestic railway vehicle equipment manufacturing industry and even becomes a commonweal technology which can be promoted outside the railway field.
