The Catenary Safety Inspection Device (2C) is installed in the train driver's cab position. It adopts adaptive high-definition image acquisition technology and provides auxiliary automatic inspection functions for railway lines by onboard crew, enabling automatic collection of line environment images. It can automatically inspect and record the status of railway catenary equipment (such as loose, detached, broken, cracked, or other abnormalities in the catenary) and the operating environment of railway lines (landslides, rockfalls, mountain torrents, floods, etc.), thereby greatly improving line inspection efficiency and automated analysis efficiency.
