FIELD: transport.
SUBSTANCE: invention relates to electrified railway vehicles. Invention covers devices and methods for measuring contact force between current collector and contact wire that allow accurate determination of contact force in both current collector 4 with one support provided with several springs 6 and current collector 4 with contact insert separated many times and provided with multiple springs 6. Proposed device comprises means for image interception composed of section camera 2 or the like for current collector spring image capture and perfection of resolution in time by partial isolation of image capture area. Besides it comprises image processor composed of PC 8 to detect spring 7 in said image by its processing and contact force compotation component to receive contact force by adding spring resistance force detected by said image processor to inertial force.
EFFECT: higher accuracy of measurement.
