System for detecting the state of a current collector
View Patent ↗A system for detecting a state of a current collector of an electrically driven vehicle includes a video camera device for digitally recording images of the current collector and an image-evaluating device for the data evaluation of the image recordings. The current collector has optically detectable markings, the position and/or shape and/or surface area and/or color of which can be detected by the image-evaluating device in an automated manner. A system that makes the automatic state detection faster and more reliable is thereby provided.
1. A system for detecting a state of a current collector of an electrically driven vehicle, the system comprising:
a video camera device for digitally recording images of the current collector;
an image evaluating device for data evaluation of the image recordings; and
optically detectable markings extending inside the current collector, said optically detectable markings having at least one of a position or shape or surface area or color to be detected by said image evaluating device in an automated manner;
said optically detectable markings including a marking disposed at a collector strip of the current collector and extending in a direction of wear of the collector strip, said marking having at least one of a position or shape or surface area or color changing with increasing wear.
2. The system according to claim 1 , wherein said optically detectable markings include a continuous marking or a plurality of separate markings disposed across a working width of the collector strip.
3. The system according to claim 2 , wherein said optically detectable markings include a marking disposed at the collector strip outside of the working width as a reference.
4. The system according to claim 1 , wherein said optically detectable markings include a plurality of markings disposed at the current collector in a distributed manner and having a defined reciprocal location in an operational state of the current collector.
5. The system according to claim 1 , which further comprises a contrast panel attached to the current collector and forming a high-contrast background marking for at least part of the current collector in a viewing direction of said video camera device.
