Example 1
The present embodiment provides a ball hitting posture training device 100 based on a racket motion trajectory, including:
the device comprises a signal acquisition module, a control module and a receiving module which are in signal connection.
And the signal acquisition module is used for acquiring attitude signals of the racket in the process of leading, hitting and swinging and transmitting the attitude signals to the control module.
And the control module is used for receiving the attitude signal of the signal acquisition module, acquiring a corresponding audio signal according to the attitude signal and transmitting the audio signal to the receiving module.
And the receiving module is used for receiving the audio signal of the control module, and the audio signal is used for a user to judge the accuracy of the shooting path, the hitting position and the swing following path and adjust the shooting, hitting and swing following actions.
The player forms corresponding impressions of sound, net passing results and landing results according to the net passing results and the landing results after the player shoots the player through multiple times of shooting, hitting and swinging actions, and the corresponding impressions of the sound track and the ball motion track are obtained. Once the athlete judges that the motion track corresponding to a certain sound track reaches the expectation, the audio signal corresponding to the sound track is judged to be the standard audio signal. The player can adjust the movement posture from the start of shooting to match the real-time sound track with the standard sound track, thereby realizing the standardization of the ball hitting action of the player. Therefore, the posture training device provided by the invention can assist the athlete to position the motion track of the racket and form correct racket leading, batting and swing actions.
In an alternative of this embodiment, the audio signal comprises: real-time beat audio signals, real-time hit ball audio signals and real-time follow-up swing audio signals;
in the continuous process of leading, hitting and following swing of the athlete, the real-time leading audio signal, the real-time hitting audio signal and the real-time following swing audio signal form a continuous audio signal.
The sound trajectory formed by the continuous audio signal may be, for example, parabolic, and gradually rises from the leading beat to the hitting beat, i.e., the sound gradually increases. From the impact to the swing, the sound trajectory gradually falls, i.e., the sound gradually decreases. The sound trajectory is formed in relation to the speed of the racket and the relative position of the racket to the ground.
For example, when the bottom line spin-up and level-hitting is taken, and the audio signal reaches the highest point of the sound track, the hitting posture of the bottom line spin-up and level-hitting is correct. When the audio signal deviates from the highest point of the sound track, the hitting posture of the spinning ball and the flat hitting ball on the bottom line is indicated to be wrong.
It should be noted that different hitting actions correspond to different sound tracks, and the audio signal at the hitting moment is located at the highest point of the sound track and cannot indicate the absolute correctness of the hitting action. Such as chipping and intercepting or passive defense in a game or handling of subconscious shots made in a random ball, the audio signal corresponding to the correct shot point for that type of ball deviates from the highest point of the sound trajectory. The athlete needs to repeatedly practice many times to develop sensitivity to the audio signal and to develop a correspondence to a particular audio signal under a particular type.
Of course, in order to show the corresponding relation between the motion and the audio signal, the real-time striking audio signal and the real-time follow-up playing audio signal are introduced. In particular operations, the real-time beat audio signal, the real-time hit ball audio signal, and the real-time follow-up audio signal may be collectively referred to as a real-time audio signal.
In an alternative of this embodiment, the signal acquisition module is an attitude sensor.
The attitude sensor is not limited to a potentiometer-type attitude sensor, an inductive-type attitude sensor, an synchro, a capacitive-type attitude sensor, an eddy current-type attitude sensor, a hall-type attitude sensor, and the like. An important advantage of digital attitude sensors is the ease of directly feeding the signals into the computer system. The sensor is developed rapidly and is increasingly widely applied.
Preferably, the attitude sensor includes a gyroscope and an accelerometer, and the angular attitude sensor can easily measure the position and the velocity. Accelerometer models include, but are not limited to, the ENZHIPU mma series accelerometer, and gyroscope models include, but are not limited to, enc-03, mpu3050, l3g4200 d.
It will be appreciated by those skilled in the art that variations to other configurations or forms of attitude sensors without departing from the spirit of the invention are intended to be within the scope of the invention as claimed.
In an alternative of this embodiment, the receiving module is a bluetooth headset or a hearing aid.
The receiving module is used for receiving the audio signal of the control module, and the audio signal is used for a user to judge the accuracy of the shooting path, the hitting position and the swing following path and adjust the shooting, hitting and swing following actions.
The athlete wears the Bluetooth earphone or the hearing aid, receives the audio signal sent by the control module through the Bluetooth earphone or the hearing aid, judges the accuracy of the shooting path, the hitting position and the swing following path, and adjusts the shooting, hitting and swing following actions.
The athlete obtains the corresponding sound track each time by means of the Bluetooth earphone or the hearing aid after multiple times of shooting, batting and swing actions, selects a standard sound track from the multiple sound tracks through the condition of passing a net and landing, and in the subsequent batting actions, the shooting, batting and swing actions are adjusted to enable the sound track obtained in real time to be overlapped with the standard sound track, so that the motion track positioning of the racket is realized, and the correct shooting, batting and swing actions are formed.
In addition, it should be noted that the bluetooth headset may receive the control instruction from the control module in a wireless signal manner. The hearing aid can assist the deaf-mute to receive the audio signal from the control module, namely the deaf-mute can also achieve good training effect through the training device provided by the invention.
