In the fields of cable laying, cable coloring and the like, accurate measurement of the moving speed of a cable is often a key technical index.

In the cable laying and cable coloring processes, the moving speed of the cable generally comes from a tractor or manpower, but due to the influences of factors such as mechanical friction of a rotating shaft and a sliding groove, accuracy of a traction force applying device, energy conversion efficiency and the like, the actual moving speed of the cable is often greatly different from the calculated speed. However, the spraying amount of the insulating paint and the ultraviolet intensity in the cable coloring are based on the calculated and measured moving speed of the power cable, and the excessively different measured values result in uneven coloring and drying of the power cable.
