[0072] The working process of the hand sensitivity training system disclosed in this embodiment is as follows: the coach uses the first hand sensitivity training device, and the student uses the second hand sensitivity training device. Since the second motor 25 of the second hand sensitivity training device is controlled by the control signal of the first driver 8, and the control signal of the first driver 8 is provided by the first encoder 26, the coach can rotate the platform 2 of the first hand sensitivity training device to make the platform 2 of the second hand sensitivity training device rotate synchronously, that is, the student's body rotation angle is controlled by the coach. Therefore, when the student is conducting hand sensitivity training, the coach rotates the body in time according to the accuracy of the student's tapping the button 5 to change the change of the student's body position during the training process, and then changes the change of the hand position, prompting the student to make corresponding position compensation for the position of the palm, which helps to improve the student's hand sensitivity training effect.

[0073] Implementation

[0074] In the third embodiment, a second driver 9 is provided on the basis of the second embodiment, so that the whole training system has two drivers, the data output port of the second encoder 26 of the second hand sensitivity training device is electrically connected to the pulse signal input port of the second driver 9, the control signal input port of the first motor 25 of the first hand sensitivity training device is electrically connected to the control signal output port of the second driver 9, and the power input port of the second driver 9 is electrically connected to the external power supply. Such a setting enables the rotation angle of the platform 2 of the second hand sensitivity training device to control the rotation angle of the platform 2 of the first hand sensitivity training device, that is, a two-way interactive control is formed on the basis of the one-way control of the first embodiment, so that two trainees can perform interactive training and mutual intervention at the same time, thereby improving the interactivity and durability of the training.

[0075] Implementation

[0076] In the fourth embodiment, two relays are provided on the basis of the third embodiment, which are respectively used to control the on and off of the pulse signals of the first driver 8 and the second driver 9. The relay will connect the pulse signal of the driver only when the button 5 is tapped correctly, and the relay will disconnect the pulse signal of the driver when the button 5 is tapped incorrectly, thereby achieving the effect of the correct party controlling the erroneous party.

[0077] A first relay and a second relay are added on the basis of the sensitivity training system disclosed in the third embodiment. The execution end of the first relay is arranged between the data output port of the first encoder 26 of the first hand sensitivity training device and the pulse signal input port of the first driver 8 to control the signal on and off between the data output port of the first encoder 26 and the pulse signal input port of the first driver 8. The control end of the first relay is electrically connected to the opening and closing part of the key 5 of the panel 4 of the first hand sensitivity training device. The execution end of the second relay is arranged between the data output port of the second encoder 26 of the second hand sensitivity training device and the pulse signal input port of the second driver 9 to control the signal on and off between the data output port of the second encoder 26 and the pulse signal input port of the second driver 9. The control end of the second relay is electrically connected to the opening and closing part of the key 5 of the panel 4 of the second hand sensitivity training device.

[0078] Button 5 transmits the closing signal to the controller by wireless transmission. If the controller determines that the closing signal of the current button 5 is the closing signal input by the luminous button 5, the controller makes the control end of the contactor work, and the execution end of the contactor is closed, so that the pulse signal input port of the driver is electrically connected to the data output port of the encoder 26; if the controller determines that the closing signal of the current button 5 is not the closing signal input by the luminous button 5, the controller makes the control end of the contactor not work, and the execution end of the first contactor is in a disconnected state, so that the pulse signal input port of the driver is electrically disconnected from the data output port of the encoder 26.

[0079] As an example, take the case where the first trainee on the first hand sensitivity training device taps the key 5 correctly, while the second trainee on the second hand sensitivity training device taps the key 5 incorrectly. The first trainee taps the key 5 correctly, the first contactor works to electrically connect the pulse signal input port of the first driver 8 with the data output port of the first encoder 26, the first driver 8 receives the pulse data transmitted by the first encoder 26, and the first driver 8 drives the second motor 25 to rotate, so that the second station 2 of the second hand sensitivity training device rotates synchronously with the first station 2 of the first hand sensitivity training device, that is, the second station 2 is controlled by the first station 2. Since the second trainee on the second hand sensitivity training device taps the key 5 incorrectly, the second contactor does not work, that is, the pulse signal input port of the second driver 9 is electrically disconnected from the data output port of the second encoder 26, the second driver 9 has no pulse data input, and the second driver 9 does not drive the first motor 25 to work, that is, the second station 2 does not control the first station 2.
