Arm-based Embedded Virtual Intelligent Fitness System

With the increasing improvement of people's living standard,people are paying more attention to their health conditions than before.Having physical health has become such an important aim to people's life that doing sports has become a necessary part in many people's daily life.However,some physical and health-care experts suggest people should pay more attention to doing sports in a scientific way.Therefore,some confusing questions,such as "How much sports capacity fits people doing sports? How much sports can help one's body exercised? And how much sports is safe to one's body?" come into being,many people do not know much about these questions,so many injuries,even serious injuries caused by doing sports,always can be seen everywhere.On the purpose of guiding people to have sports in a safe and scientific way,a virtual intelligent body-exercise system,based on an embedded form, has been designed in this paper.The system can define the suitable sports capacity that a person should have,according to the data and information which is put into by oneself,such as an individual's sex,age,height, weight as well as heart rate and blood pressure that are measured at the start of doing sports.Meanwhile,the system will track the human body's physical variations on heart rate and blood pressure by the aim to adjust the time and intensity of doing sports immediately.In this way,people can get enough exercise by doing sports and at the same time can avoid injuries caused by over-exercise.The design adopts the form of virtual instruments to control the body-exercise system.By using an embedded system,it is very convenient to embed such a system into a practical body-exercise instrument.Thus,it is easy to control the practical instrument and achieve the goal of using an intelligent body-exercise instrument.The paper describes some thought and technical methods which are related to the whole designing,such as the embedded system,virtual instrument,USB interface,the characteristics of the physiological signals and the controlling theory of sports physiology.Also the paper discusses in detail the hard wares and programs-designing of the intelligent system,which has the typical chips based on ARM7TDMI as a core;the designing process of the driving program of USB interface,which is used to connect the upper engine with the lower engine;and the fulfillment of the whole intelligent body-exercise system,which is represented and controlled by the virtaul instrument of LabVIEW.As a consequence,the adjustment of the whole system has been fulfilled and the desired goal of this designing has been achieved.
