Problems solved by technology

However, these measuring devices are generally not suitable for use anytime, anywhere in daily sports training
In addition, most of the measuring equipment related to impact such as ball speed and energy use accelerometers as sensitive components, and the analog output of the accelerometer is converted into analog / digital (A / D) before data processing, and processed into ball speed , energy and other training parameters, the equipment designed according to this method has high cost and is not easy to popularize

Embodiment Construction

[0023] Tennis training and testing device, which includes a piezoelectric sensor installed on the inner side of the triangle throat of the tennis racket, and a data processing and display module installed on the outer side of the triangle throat of the tennis racket. The data processing and display module makes the tennis racket hit the ball. The vibration signal output by the piezoelectric sensor is transformed into training parameters to be recorded and displayed.

[0024] The typical training parameters are the number of shots / the speed of hitting / the time of hitting / the energy consumed by hitting the ball.

[0025] In a preferred embodiment: the data processing and display module does not receive the vibration signal output by the piezoelectric sensor after the first time interval, enters a pause state, and continues to work after receiving the vibration signal output by the piezoelectric sensor .

[0026] Furthermore, after entering the pause state and not receiving the vibra...

Abstract

A parameter measuring method for tennis training is disclosed, which can measure the impact parameter. Its device features that a piezoelectric sensor and a data processing and dispaly module are installed to tennis racket.

Description

Technical field [0001] The invention relates to a device for measuring shock, in particular to a device for measuring shock using a piezoelectric transducer. Background technique [0002] In tennis training, both athletes and coaches need to understand the completed training parameters such as the number of shots, the speed of the shots, the time of the shots, and the energy consumed by the shots in order to arrange the training plan scientifically. For individual training parameters, such as hitting speed and energy consumed by hitting, there are already special measuring equipment for sports science research or training applications. However, these measuring devices are generally not suitable for use anytime and anywhere in normal sports training. In addition, most of the measurement equipment related to impact, such as testing speed and energy, use an accelerometer as a sensitive element. The analog output of the accelerometer is converted by analog / digital (A / D) before data p...
