Designed And Implementation Of Intelligent Table Tennis Bat

Rapid progress in science and technology,the intelligent hardware on the market at present is emerge in endlessly.Smart hardware is a new concept of science and technology after a smart phone,through the combination of hardware and software,to.modify the traditional dressing equipment,then let it has the function of the intelligent.Involved in intelligent table tennis,this article is on the basis of traditional table tennis shoot,and the corresponding intelligent hardware system,intelligent achieve the desired effect.And table tennis as a sport loved by people,both to the training of the professional sports and exercise for people,to digital table tennis sports can improve the efficiency of training and exercise of interest.Intelligent table tennis racquet hardware mainly includes:six axis pressure acquisition module,sensor module,micro controller module,bluetooth transmission module,external Flash storage module and power module.Microcontroller through the pressure signal of pressure sensor module,ADC acquisition through UART acceleration and velocity of six axis sensor module data,through the SPI external Flash memory module for data access,bluetooth module is responsible for collecting data to PC,power supply module power supply for the whole circuit system as well as to the battery.Software part mainly includes:the design of the format of the data communication and data storage format,pressure acquisition program,the acceleration and angular velocity acquisition program,data access program,bluetooth service program and bluetooth data transmission.Including pressure acquisition program is mainly to produce analog signals on ADC conversion,acceleration and angular velocity sampling procedure with kalman filtering algorithm for sensor numerical filtering in order to obtain more stable data,data access program main function of data storage and read the bluetooth service program to a part of the bluetooth 4.0 protocol,provides the service for bluetooth communication,wireless data transmission program sends the data to the PC via bluetooth module.In this paper,design of the intelligent table tennis has realized the number of table tennis strokes and strength and acceleration and angular velocity are collected,displayed and sent to the PC via bluetooth.
