基于ZYNQ的多功能列车总线通信板卡设计OA

The train communication network(TCN)is a data communication network used for interconnecting programmable devices within and between rail vehicles to transmit control information.It divides the train communication network into the multi-function vehicle bus(MVB)and the wire train bus(WTB).With the development of TCN,its application on trains is becoming in-creasingly widespread.This paper presents a bidirectional communication board based on ZYNQ for the MVB bus and parallel inter-face.This communication board utilizes ZYNQ as the core controller of the system,realizing both the hardware and software design of the MVB bus interface.The design of this communication board is simple and reasonable,capable of accurately extracting MVB master frame data,transmitting MVB slave frame data,thus achieving bidirectional communication between the MVB bus interface and the parallel data interface.
