Problems solved by technology

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 athlete is obtained by receiving multi-point sensor signals. This method cannot be used to measure the speed of the athlete. Real-time and accurate running speed at all high-density arbitrary points on track and field curves and straight track, and installation and commissioning are time-consuming and troublesome

Embodiment 1

[0029] A collection and measurement system for running speed on track and field, including a data collection device, a data transmission device and a data processing display output device, the data collection device includes a laser range finder and a laser reflector, the laser range finder Installed on a bracket, the data acquisition device is connected with the data processing and display output device through the data transmission device, the laser range finder has a rotation angle sensor, the laser reflector is arranged on the body of the measured person, and the laser range finder The laser range finder tracks the movement of the laser reflector by sending a laser signal to the laser reflector and receiving the return signal of the laser reflector to connect with the laser reflector, and the rotating device is installed on the support. The wireless or wired data transmission device transmits the time, distance and angle parameters collected by the data collection device to...

Embodiment 2

[0039] A collection and measurement method based on the collection and measurement system described in embodiment 1 for running speed on the track and field, the system includes a laser rangefinder with a rotation angle sensor and a laser reflector, and the laser rangefinder transmits a laser signal to The laser reflector and the return signal receiving the laser reflector are connected with the laser reflector, and the laser reflector is worn on the body of the person under test by strapping, bonding or wearing; the method includes the steps of setting the laser rangefinder and The step of measuring the running speed of the tested person;

[0040] The step of setting up the laser range finder is: erecting the laser range finder at the track and field position surrounded by the circular running route of the measured person, and making the laser signal track the motion track of the measured person by rotating the laser range finder;

[0041] The step of measuring the running sp...

Abstract

The present invention is a collection and measurement system for running speed on track and field, which includes a data collection device, a data transmission device and a data processing, display, storage and output device. Measure the laser reflector and system control circuit on the human body; obtain the starting position point of each movement and the time of moving to the position point, the starting position point and the moving arrival position point of each movement through the laser rangefinder that rotates following the movement of the human body The distance to the center of rotation of the laser range finder and the rotation angle of the laser range finder corresponding to the two positions are calculated by applying the cosine law algorithm to the distance from the previous position to this position, and then divided by the moving time to get this The speed of segment displacement. The invention can conveniently and quickly obtain the real-time and accurate running speed of athletes in the whole course of track and field curves and straight track.

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 ath...
