摘要: 动车组运行状态智能检测装备设置于动车段入库线上,主要针对动车组走行部、车顶和受电弓在运用中出现内部缺陷、磨损、损坏及尺寸超限的故障比率问题。实时采集运行列车的底部、侧部和顶部图像,采用故障自动识别策略,对列车的车底走行部、闸瓦、转向架、接触网等与列车有关的各个部件进行动态监控。根据实验和现场使用情况,本检测设备满足铁路机车运行时对走行部和受电弓进行在线测量检测的要求,其中,走行部检测精度可达1 mm,滑板磨耗值测量精度可达0.2 mm。鉴于此,该动车组智能检测装备能及时发现故障隐患,为检修和更换提供依据,保证动车组运行安全。Abstract: Aiming at the fault ratio problems of internal defects, wear, damage and overload size in the use of the moving part, the roof and the pantograph of the EMU, the intelligent detection equipment for EMU operating state was set to the finished line of EMU depot. The equipment was used to collect the images of the bottom, side, and top of the running train in real -time, apply automatic fault recognition strategy to dynamically monitor the state of various parts related to the train, such as the running gear, the brake shoe, the bogie, the contact network, etc. According to the experiment and field use, this equipment meets the measurement requirements for the on-line measurement and detection of the running gear and pantograph in the running of railway locomotives. The measuring precision of the running gear can reach 1 mm, the measurement accuracy of the wear value of the slider can reach 0.2 mm. In view of this, this equipment can find the problems on time, provide the basis for maintenance and replacement, and ensure the safety of the EMU operation.
