Abstract
The present disclosure provides an inspection system for contact network damage detection, including: a laser imaging radar, an X-ray transmitter, a booster, an X-ray receiver, and a control circuit board. The laser imaging radar emits a laser beam to a contact line for scanning. A laser radiation reflected by the contact line is received, and a continuous analog signal is generated, which is restored to a real-time image of the contact line. After the analog signal is converted into a digital signal on the control circuit board, a height of the contact line in a horizontal direction is calculated to determine a wear degree on an outer surface of the contact line. The booster boosts electric energy obtained by the pantograph on the contact line and supply power to the X-ray transmitter.
