Pantograph visual inspection system

POSTED 08/23/2019

Aiming at the safety of rail transit, a series of visual detection systems have been successfully developed, including online inspection system for tunnel section, pantograph machine visual inspection system and wheel visual inspection system, etc. Our visual inspection applications design to escort the safe operation of rail transit and avoid rail transit accidents.

One of our specialized applications is Pantograph visual inspection system. Pantograph visual detection system adopts multi-camera imaging technology developed by Karming's R&D team. During the train operation, real-time detection monitoring and recording of arc pulling conditions of skateboarding are performed. Angle posture and contact point are conducted, and the alarm function is triggered instantly if any abnormality is found.

Pantograph visual inspection system is functioned as data storage of testing results. The pantograph slides wear data, sheep horn position and Angle data are detected through image-automatic calculation. Besides, the inspected image and data are stored. Plus the historical detection data can be traced back the later stage. This system is mainly used in electric locomotive, train, pantograph online monitoring of the subway.
