  • High-Speed Rail Operating Environment Recognition

    different high-speed rail faults have different discrimination and treatment methods in different operating environments [4]. Take the arc detection in pantograph-catenary system as an example [5]. The light brightness has obvious affect on the arc detection, and in many arc detecting methods, we always have to distinguish the operating
