Design of Table Tennis Intelligent Scoring System Based on Accelerometer Array
Table tennis has attracted much attention in the fields of international competitions,physical education,leisure and fitness.Aiming at the problems of human error,poor training efficiency and real-time performance of players caused by the subjective limitations of referees in table tennis matches,an intelligent table tennis scoring system based on MEMS accelerometer array is proposed.In order to ac-curately detect the ball drop position of the table top,ADXL335 acceleration sensor module is used to measure the table top vibration in-formation caused by the ball table collision.By optimizing the acceleration sensor array nodes,a multi signal cooperative sensing algorithm is developed to realize the precise positioning of the ball falling point on the surface of the table.In addition,combined with the coordinate information of the ball falling point,the upper computer module of intelligent scoring and score real-time display based on the international table tennis competition rules is developed.The experimental results show that the developed table tennis scoring system has the functions of intelligent referee,real-time display of score,accurate positioning of ball drop point,coordinate information storage and so on.It provides a practical design scheme for accurate intelligent referee of table tennis competition and digital training of players.
