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.
