Design Of Data Processing System For Intelligent Table Tennis Bat Based On Android Platform

In the traditional table tennis,table tennis bat can only hit the ball,could not be analyzed on Athletes' movements,canonly rely on the guidance of coach to improve technical movement,and action observation techniques can not ensure the stability and accuracy by the naked eye,which will undoubtedly reduce the movement exercise efficiency and quality.No doubt thatit forced to increase the movement of time and energy.With the "Internet+" era,computer technology has been fully penetrated into all aspects of human activities.The emergence of the Android system has brought new development to the mobile Internet era.In order to adapt to theintelligent era of rapid development,this paper designed an intelligent table tennis bat data processing system based on the Android platform,breaking the traditional table tennis movement,make the athletes?racket and mobiles closely linked together.This paper first gives the background of the research,and then describes the advantages and disadvantages of the traditional table tennis bat,and analyzes the development of sports APP at home and abroad.Afterwards,using the Activity life cycle and four components,the Bluetooth low-power technology,SQLite database management system,and AChartEngine technology.Finally,based on the Android platform,a data processing system is designed and implemented.The parameters such as acceleration,gyroscope,pressure and so on are collected,and Bluetooth 4 communication module is used to transmit data to the intelligent terminal for data analysis,storage and uploading.In addition,the server receives the data transmitted from the mobile terminal,used to store and display motion data.Integration of server and client program to form a complete set of data processing system,so as to achieve the purpose of measuring their own state of motion,improve the technical action.The system mainlyincludes several modules:authentication module,Bluetooth communication module,processing module and display module.Authentication module is responsible for user registration and login.Bluetooth communication module is responsible for Bluetooth search,Bluetooth matching,search for Bluetooth devices that have been paired or available in the area,and the data transfer from devices to devices.The processing module is responsible for a series of processing,storage and management of received motion data.The display module is responsible for displaying the visual motion data and drawing the graph.The data processing platform of the table tennis bat has the characteristics of real-time,fast,intuitive and easy maintenance,which makes the connection between the athlete and the racket more closely and efficiently.Through the analysis of the movement data,the design gives the corresponding basis for improving the accuracy of hitting,which makes the movement more efficient and entertaining,and the market prospect is broad.
