Device for realizing interconnection between MVB bus and third-party device

A device for realizing interconnection between MVB bus and a third-party device is mainly applied to the railway field and comprises a CPU (1), an MVB module (3), a power module (15), a CPU minimum system and at least two bus communication interfaces, wherein the CPU (1) is connected with the MVB module (3), the power module (15) is connected with the CPU (1) and the MVB module (3), the bus communication interfaces are connected with the CPU (1), and data exchange is realized through the CPU (1) and the MVB module (3). Application of the device described in the implementation method realizes data exchange between a MVB and a plurality of interfaces on one product, has wider interface compatibility, realizes data exchange between the MVB bus and an AMS parallel bus, leads cabinet products based on the AMS bus and widely used in railways in China to be connectable into an MVB network, and greatly broadens application range of the MVB network. Additionally, the CPU adopted in the technical scheme has two kernels, can well complete real-time control function while realizing bus communication and data exchange, has more integrated functions, and can reduce peripheral modules and lower cost.
