近年来,高速铁路各项技术不断发展,列车运行速度从300 km·h~(–1)提高到400 km·h~(–1)。本文介绍了由韩国研究者开发和论证的技术,即400 km·h~(–1)级集电性能评估方法。此外,本文还详细解释了基于视频图像的监测技术,其不需要直接接触供电系统的任何部件,这项技术被应用于检测以时速400 km运行的高铁上架空接触网组件的稳定性。与常规使用激光传感器或者线相机(line camera)来监控架空接触网的系统不同,开发的新型系统通过视频数据来测量其处于活动状态的参数。根据在商业线路上实地测量的结果,这种系统能有效地测量架空接触网的各项参数。
In recent years, various technologies of high-speed railway have been developed continuously, and the train speed has been raised from 300 km · h -1 to 400 km · h -1. This article presents a technique developed and demonstrated by researchers in Korea, ie, a method of assessing the current collection performance of 400 km · h -1. In addition, the article also explains in detail video image-based monitoring techniques that do not require direct contact with any part of the power supply system and are used to detect the stability of overhead catenary components on HSR systems operating at speeds of up to 400 km per hour. Unlike conventional systems that use laser sensors or line cameras to monitor overhead catenaries, new systems have been developed that measure their active parameters via video data. Based on the field measurements on the commercial route, the system effectively measures various parameters of overhead catenaries.
