Design And Implementation Of Intelligent Fitness System Based On Android And ARM

With the improvement of living standards,the importance of exercise in people's daily life has become increasingly prominent.With the increase of population movement,fitness and fitness equipment types tend to diversify,but people cannot exercise with the scientific method,they often exercise at random,so that not only will not achieve the purpose of fitness,but also spent a lot of time,energy and money.Generally based on the present situation,it breeds a market urgent demand for advanced motion method,there is an urgent need to obtain a comprehensive and reliable data,and put forward a scientific guidance to help them exercise with the data.In view of the current fitness network,digital and intelligent level is not high,resulting in exercise at random,exercise effect is poor,easy to cause injury problems.Based on embedded ARM technology,WIFI network technology,Bluetooth technology and Android platform to design and implement a set of intelligent fitness system.The system consists of a central machine and each kind of fitness equipment,fitness center and machine subsystem interconnected using WIFI networking technology.As the core of the whole system of fitness center,Not only manages each fitness system,also interact with the remote server,realize the user's fitness data upload and the history of exercise data download.The fitness subsystem directly monitors and guides the user's exercise.The main contents of this paper include:1.The overall framework of the intelligent fitness system is built,and the body building subsystem is designed in detail2.The machine kinematics and dynamics model of the human body have been built According to the shoulder movement.It can show the real-time trajectory of fitness by the model,and also can display the joint angle of rotation,angular acceleration,force and torque in the process of exercise.The exercise prescription model has been also built.It can generate a scientific and personalized exercise prescriptionm according to age target,joint size and medical history.3.According to the traditional mechanical shoulder press machine fitness equipment,We build the embedded hardware and software platform,intelligent fitness equipment.The intelligence of the fitness equipment is realized.Through the platform to get the running parameters of the body,the body's physiological parameters and trajectory.4.The movement effect evaluation model is designed for the shoulder press machine fitness system,the model can be used to evaluate the effect of the single action and the whole movement process.5.Fitness APP is designed for the shoulder press machine fitness system.APP can achieve fitness equipment management,user authentication,data query,motion data upload and download,fitness exercise prescription Download.
