The Design And Implementation Of Fitness Sports System Based On Android Cellphone

Fitness sports system is an application service system to promote health based on the Android Smart Phone,which helps primarily individual and enterprise(groups)users understand the sports data that day and historical to improve the health consciousness.Through the analysis of research background and significance of fitness sports system,this paper particularly introduces four aspects according to the software development process: the related technology,the system user,the system requirement and the system use case,and demonstrates the feasibility of the fitness sports system.Then this paper make an detailed elaboration about the reliability of the system,the data interface,the database,the function module design as well as the mobile phone pedometer algorithm and the design method of data gateway as the focus of the paper.Finally,it make a detailed description on the main functions of the fitness sports system to form a completed whole.such as registering,landing,sports,route planning and sports of enterprise staff,etc.Fitness sports system is developed based on the Eclipse development platform,which can convert the acceleration of mobile phone into electrical signals using the built-in acceleration sensor of Android smart phone to record the movement status of exerciser,and to denoise the received electrical signals using the fast Fourier transform(FFT)filtering algorithm,and to implement the step counter of mobile phone through obtaining the user movement data for setting dynamic threshold.By setting up the data gateway,the user motion data is collected from the motion pedometer to the local persistent data storage,and to achieve the function of fitness sports system statistics,such as statistical query by analyzing the user’s motion data.According to the fitness sports system,users can get the exercise data that day in real-time,including sports steps,sports time,sports distance,consumed energy and ranking of sports data,etc.Fitness sports system has a complete function and stable performance,which can meet the need of users and has a high practical value.
