摘　　要：目前在乒乓球颠球趣味体育比赛中均采用的是人工计数方式,由于人的视觉和听觉分辨率有限,这样参赛者的成绩不仅受计数裁判人为因素影响较大,而且每一名参赛者都需要一名裁判来为之计数,还浪费了大量的人力资源。本文提出了利用压电传感器来检测颠球信号,并通过单片机处理后由数码管输出显示,计数测量快速准确,保证比赛的公平和公正,大大提高了工作效率。At present, manual anything methods are used in table tennis competitions which are juggling interesting sports, because of human visual and auditory resolution is limited. So that the results of the contestants are not only greatly affected by the counting of the human factors, but also needs a referee to count, which was wasted a lot of human resources .This paper describes the use of piezoelectric sensor, which can detect the ball signal. So people can use the digital tube to display through the processing of the SCM. This counting measurements are quickly and accurately, which can ensure the fairness and justice of the sports, greatly improving the efficient of the work.
