DEVICE FOR MEASURING SPEED OF VEHICLES

摘要

FIELD: transport engineering. SUBSTANCE: axle 1 is provided with conical disk 2 provided with concentric rectangular steps 3. The disk is connected with automatic centrifugal mechanism that provides movement of the conical disk along axle 1 depending on the speed of its rotation. Depending on the value of the displacement of the conical disk different stages are exposed to a laser beam. The reflected beam enters a receiving unit and then to the unit for processing information. EFFECT: improved accuracy of measurements.
