Description

Ball Speed Measuring System

The invention relates to a speed measuring system for ball games and is an auxiliary equipment for sports science.

In throwing ball sports such as baseball or softball, the player's pitching speed is a very important performance indicator; at present, the laser speed gun is mainly used to measure the ball speed, but because the speed measurement principle is mainly based on the influence of the moving ball on the laser signal. The Doppler effect is generated, so in addition to the accuracy of the speed measurement is extremely dependent on the placement of the speed gun, it is also easily affected by the obstruction of the surrounding objects or objects.

In view of the above-mentioned shortcomings, the creator of this new model believes that it is necessary to correct it. Based on years of experience in related technologies and product design and manufacturing, and adhering to the excellent design concept, he researched and created the above-mentioned disadvantages. After continuous efforts, he finally This is the launch of this new creative ball game speed measuring system, in order to correct the product structure and improve the product's excellent efficacy.

The main purpose of this new ball game speed measurement system is to provide a measuring device that can measure ball speed more accurately than a laser speed gun.

In order to achieve the purpose of exposing, the new creative ball game speed measuring system includes: a measuring ball with a sphere, the sphere is provided with a distance measuring transmitter, an indicator, a start button and a control module, the distance measuring The transmitter, the indicator and the start button are all electrically connected to the control module; A receiving computing device has a host, and the host is electrically connected to a display and a receiver wirelessly connected to the distance measuring transmitter at the same time; a receiving ball sensing device has a receiving ball, and the receiving ball is provided with a sensor. The sensor is electrically connected to the host.

When performing speed measurement, the subject holds the measuring ball and presses the start button, so that the ranging transmitter sends two ranging signals to the receiver at predetermined time intervals, and the host knows the traveling speed and transmission of the ranging signals. time interval, and the time interval between receiving two signals will be extended due to the distance between the receiver and the ranging transmitter, and the host can calculate the distance between the receiver and the ranging transmitter based on this, and measure After the distance is completed, the subject throws the measuring ball to the receiving ball, the sensor will get an impulse value due to the impact of the ball, and the host can then calculate the ball speed value according to the measured distance value and impulse value; Compared with the current laser speed gun, this creation uses the distance value and the ball's momentum value to calculate the ball speed value, so it will not be affected by the placement of the instrument or the movement of people around, so a more accurate ball speed value can be obtained. It is obvious that this work is a product with high practicability and reliability.
