Table tennis referee and player training system and method based on acceleration sensor

Abstract

The invention belongs to the technical field of sensor intelligent monitoring, and in particular relates to a table tennis referee and player training system and method based on an acceleration sensor. It includes a table tennis table, several acceleration sensor node units arranged on the table tennis table, a circuit processing unit and a data analysis unit. In the present invention, the particle swarm optimization algorithm LCSO is used to calculate and determine the optimal distribution mode of the sensors on the table, and then when the table tennis ball falls on the table, three acceleration sensors measure the vibration intensity to determine the position of the contact point of the falling ball And use the storage module to record the coordinates of this point, process and convert it into a score form, and then give a judgment whether to score. The present invention not only has the function of automatic scoring in real time, but also can summarize the playing habits of the players by storing and analyzing all the ball drop positions of the players, so as to realize the purpose of guiding and improving the players' playing methods.

Description

technical field [0001] The invention belongs to the technical field of sensor intelligent monitoring, and in particular relates to a table tennis referee and player training system and method based on an acceleration sensor. Background technique [0002] With the advent of the era of national sports, table tennis has become more and more popular in people's lives as a common sport with a large number of people participating. However, the training and referee system of table tennis often requires a lot of manpower and material resources, especially in During the epidemic, due to the prohibition of gathering activities to prevent the spread of the disease, table tennis training and refereeing are more difficult. At the same time, due to the limited recognition of human eyes, misjudgments or missed judgments often occur during the refereeing process of table tennis games, especially for the judgment of edge balls , due to the fact that the edge ball is often very fast and it is...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem in the prior art that in table tennis competitions, relying on image comparison and judgment for scoring, the accuracy is low and the detection range of the existing sensors installed on the table tennis table is very limited, and it is impossible to find the trainer through the algorithm. Disadvantages of commonly used ball-playing methods and suggestions for improvement to trainers provide a method that can not only realize the automatic scoring function, but also can guide and improve players by storing and analyzing all the players' falling ball positions and summarizing the players' playing habits.
