Design And Implementation Of The Tennis Training System

In recent years,with the improvement of the material level,people are more and more concerned about their own health problems,therefore,sports and fitness are becoming more and more indispensable in people's life.In order to make their sports level more professional,people pay more attention to the intelligent sports equipment besides high price hiring personal trainers.At the same time,the development of science and technology makes the function of intelligent sports equipment become more perfect and professional,therefore,intelligent sports equipment could better help people improve their sports quality and strengthen their own physical quality.The tennis sports training system belongs to intelligent sports equipments.It can collect the motion data in real time through the motion sensing module fixed at the bottom of the racket handle of the tennis racket and transmit the motion data to the APP terminal of the tennis sports training system through the wireless transmission function of the sensing module.Through these motion data,the APP can analyze and solve the tennis players' technical movements in tennis in real time and calculate the number and percentage,and the speed of the beat,and show them through the APP software interface of the mobile phone.In this paper,the tennis training system is mainly composed of two parts,which are the motion acquisition sensing module fixed at the bottom of the tennis racket handle and the APP software which is responsible for collecting and analyzing the motion signal.In this paper,in the design of the motion acquisition sensor module,the hardware circuit includes the multi axis inertial sensor detecting the real-time motion,the microprocessor used to collect inertial sensors,the lithium electric protection unit and the lithium battery.The embedded software of the sensor module takes into account the power factors and the convenient use of the sensing module.The design completes the functions of sensor data acquisition,low power wireless transmission,one key switch machine and intelligent dormancy and remote sensing on electricity.The APP part of the mobile phone designed in this paper has the functions of wireless communication with sensor module,real-time collection of motion information,preservation of motion information,analysis and display of tennis results and so on.The whole system is coordinated and stable,and tennis players can grasp their movement situation in real time in the process of movement through the system.
