Abstract :
A double sheet detection system with ultrasonic sensors is designed for providing scanning equipments with rapid and accurate double sheet detections and it´s suitable to different kinds of paper. It is composed of the circuit to transmitting ultrasonic wave, the circuit to process ultrasonic wave received and the determination circuit. The system can give an alarm signal to the scanning equipments when there is double sheet to avoid paper jam or leaky scanning. Thanks to the high speed and high accuracy, the scanning trouble and resource wastes can be reduced, thus improving greatly the automatic extend for the scanning equipments.
