Detecting Vehicle Separation

To detect vehicle separation in an Automated Vehicle Classification (AVC) system.

Description

An Automated Vehicle Classification (AVC) system measures the height and counts the number of axles of a vehicle. This application uses a MINI-ARRAY measuring light screen to detect vehicle separation in an AVC system.

The MINI-ARRAY senses a vehicle when its beams are blocked. The treadle counts the number of axles until the beams of the MINI-ARRAY are no longer blocked, when the vehicle has passed. The photoelectric sensors determine the height of the vehicle.

The information from the MINI-ARRAY, the photoelectric sensors, and the treadles is sent to a lane controller that assigns the number of axles to the vehicle that was detected.

The most difficult situation for an AVC system is the detection of a vehicle that is towing a trailer. The resolution of the vehicle separation system must be small enough to detect the hitch of the trailer. The MINI-ARRAY system can reliably detect the trailer hitch, so the trailer is included with the proper vehicle.
