The Design of a Basketball Goal Automatic Detector

In order to solve slower testing and lower degree of electronic information in current college entrance physical examination, we designed a basketball goal automatic detector. The designed system consists of single chip microcomputers, ultrasonic and infrared sensors. In this system, the basketball goal can be automatically detected and correctly judged by using ultrasonic sensors installed in the backboard and infrared sensors installed in the basket. The results are displayed in LED via RS485, and at the same time, sent to the upper computer via RS232. Experimental results showed that, compared to the existing systems, the designed system's installing restricts reduced. Enhancing objectivity, reducing labor costs, and more fairness were achieved by using this system.
