复兴号服役动车组弓网受流性能数据跟踪采集方法研究

Research on Tracking and Collecting Method of Pantograph-catenary Current Collection Performance Data of Fuxing EMU

利用复兴号服役动车组配备的弓网监控系统,采用计算机视觉技术对弓网视频图像序列进行离线处理,智能识别接触线和受电弓滑板接触点,采集弓网燃弧图像,测量受电弓动态包络线数据,包括受电弓横向摆动量和动态抬升量。为长时间追踪服役动车组的弓网受流性能变化,掌握不同时期的弓网受流性能规律提供技术支持。

Using the necessary on-board pantograph-catenary surveillance system of“CR400”,the off-line processing of pantographcatenary surveillance video image sequence is carried out by using computer vision technology.Related contact points between pantograph slide plate and contact line are intelligently identified,the pantograph-catenaryarcing images are collected,and the dynamic envelope data of pantograph including transverse swing and dynamic lifting of pantograph is measured.It provides technical support for tracking the change of pantograph-catenary current collection performance of“CR400”for a long time and mastering the pantographcatenary current collection performance in different periods.
