Design and Implementation of MVB Communication Network Card Based on Domestic Chip
Multifunctional vehicle bus technology is the core technology of train communication network.In order to solve the constraints of imported chips on production design of MVB products,we conducted in-depth research on domestic chip design companies,chip manufacturers and chip types with high market share.In the design process of MVB communication products based on domestic devices,a MVB protocol controller based on FPGA technology and semiconductor is developed.The function and performance of the domestic MVB communication network card are approved through the loading type test and consistency test.The research results show that the MVB communication network card based on domestic components has the characteristics of convenient maintenance,low maintenance cost,stable performance and so on.It can match well with the traction system,signal system and braking system,meet the needs of similar products in depth autonomy and control,finally provide a reference scheme for the realization of domestic vehicles.
