Abstract

The invention relates to a system and method used for acquiring and measuring running speed in a ground track field. The system includes a data acquisition device, a data transmission device and a data processing, display, storage and output device; the data acquisition device includes a laser range finder with a rotation angle sensor, a laser reflector arranged on the body of a measured athlete and a system control circuit. According to the system and method of the invention, a time of a movement beginning position point and a time of a movement arrival position point, distances from the movement beginning position point and the movement arrival position point to the rotation center of the laser range finder, and laser range finder rotation angles corresponding to the two positions are obtained through the laser range finder which rotates with the movement of the body of the athlete; a distance of a last movement position to the current movement position is calculated through using a cosine law algorithm; and the distance is divided by movement time, so that the speed of the athlete in the distance can be obtained. With the system and method of the invention adopted, real-time and accurate running speed of the athlete in curve and straight tracks in the ground track field can be obtained conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of sports training parameter collection, and specifically relates to a system and method for collecting and measuring running speed on a track and field field. It is used to collect running speed on track and field curves and straight track. Background technique [0002] In sports training, it is very important to scientifically guide sports training and improve the level of sports skills how to use modern scientific and technological means to collect athletes' running speeds on track and field curves and straight track as accurately and in real time as possible. At present, there is no technology and product that can meet the demand for real-time and accurate full-range speed measurement of curves and straight lines. The existing method is a segmented speed measurement method. Multiple sensor signal receivers are set at multiple points on the athlete's running route, and the movement information of the ...
