Design Of High Reliable And Real Time Wireless Exercise Monitoring System For Big Data

According to the progress and development of society,people’s living standards have been significantly improved,but at the same time,exercise time of people is less than before,health problems have become increasingly prominent.According to the students’ physical test data in recent years,the physical fitness of students is gradually declining,and the weak problems in adolescent obesity are more and more serious,therefore paying attention to young people’s physique is now one of the most arduous task of society.In order to improve the students’ physical constitution,the national education ministry put forward a slogan,"sunshine long-distance race",calling on students to participate in physical exercise.However,the facilities is not perfect,meanwhile the lack of scientific management methods is also an hard problem.On one hand,college teachers can not get the exercise data of students.On the other hand,enthusiasm and autonomy of students who participate in the extracurricular physical exercise is extremely scarce.In order to solve these problems,this topic combined with the Internet of things technology,WEB technology,develop a high reliable and high reliable wireless monitoring system for the management of students’ Extracurricular running exercise.On the basis of the existing outdoor sports management system,this dissertation designs and realizes a set of multi function and network management system of extracurricular physical exercise.This system is divided into four parts: data acquisition terminal,data forwarding node,data forwarding base station and WEB query system.Data acquisition terminal and data forwarding node,data forwarding base station use the wireless transmission protocol which is independently invented by our team to communicate.In order to achieve function of loss packet retransmission,fault monitoring and anti-collision.Data transmission between the base station and WEB query system using a stable and reliable HTTP protocol and using JSON format.Data acquisition terminal has the function of data acquisition,data display,fault alarm,distinguishing swiping card for other people.Data base station achieves functions of data acceptance,data forwarding,data backup and broken network retransmission.Students can quickly query their running results through WEB query system,administrators can download and modify the students’ scores through WEB system.According to the students’ physical fitness test scores and BMI index,students will be divided into several groups,and system will makes an exercise plan for each group.This system realizes the unmanned management of the network,intelligence,and other functions.In this system,the data acquisition terminal uses RFID technology,using the ISO14443 protocol to read the information on campus card.Face recognition system using OPENCV database.According to face recognition,system can determine whether someone is swiping more than one card.Wireless transmission system uses 433 MHz wireless transmission module and the transmission distance can reach 2 kilometers.The microprocessor of the terminal and the data base station is the 32 bits processor STM32F103VET6 produced by ST company.WEB query system uses MVC framework,which is developed in Python language.At present,this system has been put into use in many colleges and universities.The system has stable operation in some schools for more than two years.With the operation of the system,the extracurricular sports are under stable and efficient management,realizing scientific control exercise,enhancing student movement,improving the physical fitness of students.After putting into use,this system is well accepted by teachers and widely arouse the interest of the teachers in other universities.The acclaim of teachers has highlighted the research value in sports management and significance of the topic.
