摘　　要：随着列车通信技术的发展,故障诊断和数据记录已成为保障列车运行的重要手段,因此需要一种高速度、大容量的数据记录系统来收集列车网络产生的信息。设计了一种基于可编程片上系统(SOPC)技术的多功能车辆总线(MVB)解码与记录装置,结合嵌入式处理器与可编程逻辑器件软硬件协同工作的优势,将MVB实时解码和大容量存储集成于单块FPGA芯片内。装置以在线监听总线的方式,收集MVB设备的状态监测和故障诊断信息,为分析列车运行的安全性与可靠性提供依据。With the development of train communication technology,fault diagnosis and data recording has become an important means to ensure the train operation,a highspeed,large-capacity vehicle data recording systemis needed to collect information generated by the train network.In this paper,a MVB analysis and recording system based on SOPC technology is designed,which combines the advantagesin the collaborative work of embedded processor and programmable logic device,and integrates the real-time decoding and mass-storage on one single FPGA chip.The system could collect condition monitoring and fault diagnosis information,and provide the basis for analyzing the safety and reliability of the train operation.
