Problems solved by technology

[0002] In sports training and traditional martial arts training, footwork training is very important. According to statistics, in fencing, boxing, and taekwondo, footwork training even accounts for about 40% of the total training, but the extraction of footwork However, there is a lack of characteristic tools, especially for the training center to extract the universal tools for the characteristics of steps. In some events, the accuracy of athletes' movements is judged solely by the coaches' naked eyes and experience, and athletes can only judge from a macro perspective. Understand your own training situation, and you can’t know the microscopic technical parameters, such as the completion of each step in fencing, the kick force at the front and rear conversion points, and the distance between the two feet during the entire training process These parameters are very helpful to coaches and athletes, but it is difficul

Embodiment 1

[0040] Take fencing as an example, see image 3 , 14 pieces of assembleable digital venue modules 5 form a 14m×1.6m assembleable digital venue 10, and the computer 7 software system database stores the footwork of various fencing routines, and records the center point of force of each step, Stress time, flight time, vibration frequency of the feet at fixed points, when the movement is completed, and the kick force at the front and rear transition points. To record this routine, mark the steps 12 on the digital site through the projected light 13 of the projector 9;

[0041] Turn on the computer 7, initialize the hardware, and the athlete 11 starts to practice. The athlete 11 trains successively according to the already calibrated pace. The flexible array pressure sensor unit 2 of the assembled digital field module 5 obtains the pressure signal, and the signal passes through the row lead and the column lead. After filtering, amplification, and A / D conversion, it is connected t...

Embodiment 2

[0043] Taking the electronic lock as an example, the user's step characteristics of the electronic lock can be used as the unlocking signal. The electronic lock is connected to the host computer, and the host computer is connected to the assembleable digital field module 5 through the field bus 6. See figure 1 , figure 2 , let the user of the electronic lock make a set of actions that he memorizes in the assembleable digital field module 5, and record the characteristics of his steps into the database. Time, vacating time, the surface layer 1 material of the digital field module 5 is selected from the same material as the surrounding floor, and six digital field modules can be selected to form a 3×2 rectangle. 5 to make a set of actions that the user exists in the database, the assembleable digital field module 5 collects the step characteristics of this set of actions, and the computer 7 compares the user's step characteristics with those in the database to obtain a similari...

Abstract

The invention relates to an assembly digital field based on a flexible array pressure sensor and a method for training gait. Parameters of an athlete including action time sequence, action frequency, position calibration, stress center point, stress time and flight time can be acquired through acquiring information including pressure of foot soles of the athlete contacted with the flexible array pressure sensor unit in the assembly digital field. The digital field and the method have the advantages that the requirement of real time can be met in longer distance; the module of the assembly digital field can be disassembled and assembled arbitrarily, and can extract gait characteristics on multiple sports training events; and the athlete can correctly recognize the training effect of the athlete self through a sports effect evaluation system and an expert system, and adjust the training plan in real time. The digital field and the method can also be applied in the field of mode recognition.
