The working principle of the wholesale infrared vehicle separator is to realize the synchronous scanning of the vehicle through the non-contact linearly arranged infrared light transmitters and receivers, and convert the optical signal into an electrical signal, so as to realize the comprehensive detection of the vehicle data.​​

The infrared vehicle separator is mainly composed of illuminator and receiver, and adopts the working principle of through-beam. A plurality of infrared light emitters and infrared light receivers are respectively provided at both ends of the lane perpendicular to the driving direction. The number of transmitters and receivers of the wholesale infrared vehicle separator is the same, and they are aligned longitudinally and in corresponding positions, so as to realize synchronous scanning of vehicles.

When the vehicle passes through the lane, the ray emitted by the transmitter of the infrared vehicle separator will be blocked by the vehicle, and the corresponding receiver cannot receive the ray, thus judging that there is a vehicle passing through, and sending the vehicle separation. In addition, the wholesale infrared vehicle separator can also detect the hooks between the full trailers, which ensures the correct correspondence between the weighing detection data and the vehicle. The wholesale infrared vehicle separator provides a reliable basis for vehicle separation detection.
