摘　　要：在城轨车辆网络中,MVB通常用于车辆级数据的传递,而具体到制动子系统,则通常使用内部CAN网络进行数据的分发和收集,因此,制动系统需要具备网关功能,以实现MVB和内网CAN间的数据传递和协议转换。所研制的MVB网关板卡,以Xilinx Zynq SoC为协处理器,实现MVB协议处理;以NXP MPC系列MCU为主处理器,实现与协处理器间的主从通信,以及对报文数据的转发和对CAN协议的处理。通过对板卡的通信功能进行测试与第三方试验认证,证明板卡已经为装车运用做好准备。相较于传统地采用商业化MVB协议处理模块,代之以SoC协处理器实现MVB的协议处理,确保了设计的灵活性和自主可控,经济成本可降低到原来的约15%。In the urban rail vehicle network,the braking system needs to have a gateway function to realize Data transfer and protocol conversion between MVB and CAN.The MVB gateway board developed in this paper uses Xilinx Zynq SoC as a coprocessor to realize MVB protocol processing,and uses a NXP MPC series MCU as the main processor to realize master-slave communication with the coprocessor,while realizing CAN protocol processing.Compared with the traditional commercial MVB protocol processing module,the MVB protocol processing is implemented by the SoC coprocessor,which ensures the flexibility and controllability of the design,and greatly reduces the economic cost to about 15%.
