摘　　要：南京地铁1号线运营10年以来,列车在正线运行中发生的故障数量和类型都越来越多,但车上现有的诊断设备记录车辆关键数据的能力有限,当车辆发生故障时,并不足以给维修技术人员提供全面的信息。针对此问题,对车辆World FIP网络协议进行研究,开发了的车辆数据记录仪。该记录仪通过专用隔离变压器接入列车World FIP网络总线,在物理层解决网络接入问题的同时,根据网络节点特征及变量特征进行协议分析,并结合已有的变量定义,解析并记录FIP网络中的所有通信数据。通过实际应用中的数据对比可以看出,所设计的车辆数据记录仪能持续且较全面地记录所有World FIP网络上的通信数据,非常有利于故障的查找和分析,从而能准确地解决故障、提高车辆故障的处理效率。The variety and amount of vehicle faults occurred in the main line operation of Nanjing metro Line 1 constantly increased in the past ten years. However,the recording capability of existing devices installed in vehicle for key data is very limited,in case of vehicle fault,comprehensive information could not be provided for maintenance technicians. In view of this problem,a new vehicle data recorder is developed after thorough researches on the network protocol of WorldFIP. This recorder is connected to network bus of WorldFIP by a special isolation transformer,it can analyze and record the communication data in FIP network according to variable definitions. Data comparison in practical application shows that the newly designed vehicle data recorder can record all the communication data in FIP network continuously and comprehensively,solve vehicle faults and enhance the processing efficiency of vehicle faults,therefore,it is very convenient for the analysis and location of vehicle faults.
