Design and Performance of Infrared Subsystem for Separating Vehicles

In a vehicle feeing system with magnetic card, the infrared subsystem for separating vehicles is an important equipment which is a plane measuring system with parallel infrared rays in equal distance from one another. Its performance will directly affect the operation of the feeing system. The design of this subsystem is presented and the performance is analyzed in this paper. The results indicate that, after using the related testing technique, the subsystem can efficiently suppress not only the outside interference and noise, but also that from adjacent infrared signals.
