Design and experiments of a football field bounce rate detector

At present, detection of football bounce rate on football fields is mainly based on manual method in China, which is labor intensive and has low detection accuracy. To solve this problem, based on the photoelectric sensor arrays, an optical detection method is proposed for measuring football field bounce rate. A football clamping mechanism has been theoretically analyzed and then a simple and reliable football holding device was developed to perform clamping and release. A control system of the football field bounce rate detector has been constructed based on modular design principles. The detector was completed on this basis, which can achieve gripping, lifting, releasing football and bounce rate calculation. Experiments showed that the errors of detection accuracy of this equipment are not more than 1%, fully satisfying the relevant national standards.
