Motion information collection system for rowing athlete

Abstract

The invention discloses a motion information collection system for a rowing athlete. The system comprises a collection module, a first communication module, a second communication module, a main control module and an intelligent terminal; the collection module is used for collecting motion information of the athlete, and the motion information is transmitted to the main control module through thefirst communication module; the main control module is used for parsing and restoring the received information into motion posture information of the athlete and is in communication with the intelligent terminal through the second communication module. According to the system, the athlete only needs to wear the collection module, the motion information of the athlete can be collected, it is not necessary to refit equipment such as a ship body and paddles, and the cost is reduced. The invention further discloses a motion posture restoring method for the rowing athlete. By means of the method, the collected motion information of the athlete can be parsed and restored into the motion posture information of the athlete, the method principle is simple and efficient, the motion posture information can be displayed in real time through the intelligent terminal, and long-distance monitoring for the athlete can be achieved precisely.

Description

technical field [0001] The invention relates to the field of sports information collection of athletes, in particular to a sports information collection system for rowing athletes. Background technique [0002] Rowing water sports are the key research projects of the "119" project of the National Sports Commission, including: rowing, kayak, rowing boat, sailing boat, windsurfing, etc. The effect of rowing athletes sliding in the water is the core for coaches to test the quality of athletes' training. It is mainly reflected by the gliding speed of the hull in the water, the speed of the athlete's paddle pulling, the range of paddle pulling, and the force on the paddle handle. The conventional acquisition and analysis of the above-mentioned motion postures is generally completed in two ways: [0003] 1) Coaches conduct subjective analysis by watching sports videos; [0004] 2) By installing load cells and infrared displacement sensors on the hull, sliding seat, and paddle fr...

AI Technical Summary

Problems solved by technology

[0006] 1) Significant modification of other equipment such as the hull and oars is required, and the collected signals are analog signals based on old-fashioned sensors, which cannot be output and analyzed in real time, nor can complete and precise monitoring of long-distance rowing;

[0007] 2) A variety of sensors are required, and there are many types of sensors, mutual signal interference, and poor signal stability;

[0008] 3) The method of correcting and analyzing and restoring the motion information collected by the sensor into athlete's motion posture information is cumbersome and complicated, and the reduction efficiency is low;
