Embedded component for ball for sports training and preparation method of embedded component

Abstract

The invention discloses an embedded component for a ball for sports training and a preparation method of the embedded component. A core control unit is connected with a combined inertial measurement unit through an RS485, the input end of the core control unit is electrically connected with the output end of a ball pressure detection module, and the input end of the core control module is electrically connected with the output end of a clock module. The component uses an STM32ARM controller as the core control unit, the ball pressure can be monitored through the ball pressure detection module, the core control unit receives ball pressure signal transmitted by the ball pressure detection module, by setting the standard ball pressure, whether a buzzer alarm is controlled to give an alarm or not is determined, a three-axis gyroscope and a three-axis acceleration sensor of the inertial measurement unit can transmit the information to an attitude angle information fusion filter circuit in real time, the signal is then transmitted to the core control unit, the information is transmitted to an external device or a smart bracelet through a Bluetooth module, and therefore the movement condition of the ball can be monitored.

Description

technical field [0001] The invention belongs to the technical field of sports equipment, and relates to an embedded component of a ball for sports training, and more specifically, to a method for preparing the embedded component of a ball for sports training. Background technique [0002] With the development of communication technology, various intelligent balls have appeared in the field of sports balls (such as basketball, football and volleyball) to better realize the interaction between people and balls at different levels. Yet, in existing intelligent sports ball, there are many technical problems. [0003] Technical problem 1: To solve the energy supply of the sensor, the traditional method is to use wireless charging to supply power to the sensor. The disadvantage of this method is that it needs to be charged before each game, which is inconvenient to operate and cannot be used at any time. Effect, in addition, in the process of playing, if the power supply of the s...

Problems solved by technology

[0003] Technical problem 1: To solve the energy supply of the sensor, the traditional method is to use wireless charging to supply power to the sensor. The disadvantage of this method is that it needs to be charged before each game, which is inconvenient to operate and cannot be used at any time. Effect, in addition, in the process of playing, if the power supply of the sensor is insufficient, it needs to be recharged, resulting in interruption of playing

[0004] Technical problem 2: data transmission problem, the traditional method uses wired methods to export data, and the real-time performance is greatly reduced

[0005] Technical problem 3: The sensor is implanted in the basketball, and the weight of the ball will deviate from the normal basketball, and this deviation will be caused at various angles, causing the ball to not follow the normal basketball trajectory during flight, and losing the meaning of the basketball itself

[0006] Technical problem 4: The ball touches the ground several times, and it will vibrate, causing signal deviation and damage to the peripheral devices of the sensor, and it is inconvenient to maintain

[0007] Technical problem five: The sphere is implanted with sensors, which will form dents or bumps on the surface of the sphere. During the process of shooting the ball, the dents (dents) touch the ground, making the basketball not bounce according to the normal track.
