Study On The Fall Detection Algorithm For Marathon Movement

In 2014,the State Council issued a number of opinions on speeding up the development of sports industry and promoting sports consumption.[1] clearly pointed out that the national fitness is a national strategy,and the popular fitness boom has sprung up in China.With the development of the national fitness campaign,the marathon is becoming more and more popular among the public,especially in the past three years.The marathon movement tide swept China,and the problem of sports safety followed.During the marathon movement,the human body was in a physiological limit for a long time.If the accident fell,it would harm the body of the athletes,and the serious situation would jeopardize the safety of life.If we find out and rescue measures in time of fall,we can greatly reduce the disability rate and mortality rate.In order to solve this problem,through consulting the literature,consulting experts to determine the experimental scheme and experimental equipment design,through the design of a fall simulation experiment to achieve a threshold of acceleration,a set of fall detection algorithm suitable for marathon movement.And realizes the alarm logic through the host computer programming language.The experimental results show that the algorithm can effectively divide fall and other daily life behaviors,and has higher alarm rate and lower false alarm rate.In this paper,based on the characteristics of Marathon movement,the research and Realization of the athlete's fall detection algorithm is applied to the marathon monitoring system.When the athletes fall,the fall alarm is issued,and the GPS positioning in the system is used to locate the falling object quickly and accurately,and take timely rescue measures to ensure the athletes.It's safe.
