VEHICLE DETECTION ZONAL SENSITIVITY DIFFERENTIATING SYSTEM USING A LASER, CAPABLE OF SENSING TRAVELLING OF A VEHICLE ONLY ACCURATELY WITHOUT MALFUNCTION DUE TO FALLING LEAVES, SNOW AND RAIN

摘要

PURPOSE: A vehicle detection zonal sensitivity differentiating system using a laser is provided to improve reliability of the operation.;CONSTITUTION: A vehicle detection zonal sensitivity differentiating system comprises a laser emission module (100), a laser receiving module (200), a pulse generator connected to the laser emission module and the laser receiving module and a distance measuring part. A central axis of a light transmitting lens (103) of the laser emission module and a light receiving lens (203) of the laser receiving module are within the distance range of 6m-18m from a target, a vehicle, and in the angular range of 0.5-5 degrees.;COPYRIGHT KIPO 2013
