Design And Application Of Digital Shoe Information Feedback System Based On Soft Sensor

In recent years, domestic and foreign researchers use biomechanics and biochemical method to do research in race walking and progress the level of training. However, in the field of athlete's technology diagnosis, there are still some problems. People always use pickup camera to take video of athlete's training and test the concrete data of every parameters from the graph. There are two kind of camera, one is fixed, the other is tracking one. Fixed cameras can only record the athletes take the four-step action; tracking camera can record the whole process of training athletes, but can not provide the technical parameters of the quantitative data. Therefore, race walking project needs a new kind of monitoring method which can not only analyze athletes'technology but also provide the result of analysis in the form of quantitative data.In response to the problems in last paragraph, with the help of Chinese Sport Administration and the Track and Field sport managing center. We deeply studied the nature of race walking and developed a system using for sampling sports parameters of athletes. This article summarizes the major work are as follows:On the basis of research in the nature of race walking and the needs of this sport project, we identified the kinematics and dynamics parameters. We designed a kind of technology test and information feedback system which based on flexible array pressure/tactile sensor, so solve several problems such as sample the foot pressure of athletes, real-time monitoring the technology of athletes and feedback sports parameters. Using this system we will no longer analyze technology of athletes after training but indicating at training. And this will be benefit to cultivate athletes'technology harmony and rhythm.Studied the relationship of race walking sports parameters; studied the physical and technological dynamic changes of athletes when training and in race; established a series of sports parameters of technology without speed limitation.Through the comparison between Chinese and foreign outstanding race walking athletes, we could get the problem in technology of Chinese athletes. By testing on the same player for a long time, we could offer pieces of advice on technique. Integrated velocity structure, physical distribution, and sports parameters, we could do deep research in the strategy of men's 20km race walking competition.In this paper, the technology monitoring method is analyzed which result could improve training method and technology of race walking athletes, also could offer important materials for cultivating youngsters.
