The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the vibration suppression glove for suppressing the tremor movement of the hand comprises a glove 10 and a tremor suppression device 20, wherein the tremor suppression device 20 is arranged on the glove 10 at a position corresponding to the back of the hand of the human. Tremor suppression device 20 is a tremor suppression strategy based on the motion signals of the human hand and not based on muscle group signals, and is thus a wearable device for hand tremor suppression.
As shown in fig. 2, the tremor suppression device 20 includes a signal acquisition unit 21, a signal processing unit 22, and a tremor suppression signal generation unit 23, wherein an output end of the signal acquisition unit 21 is electrically connected to an input end of the signal processing unit 22, and an output end of the signal processing unit 22 is electrically connected to an input end of the tremor suppression signal generation unit 23.
Wherein,

Example four
As shown in fig. 5, in an embodiment, the tremor suppression method for suppressing tremor movements of the hand includes a method for automatically generating a tremor suppression strategy, which specifically includes the following steps:

Preferably, in one embodiment, when the hand starts to generate tremor movement, the signal acquisition unit preferably acquires the movement data of the tremor movement of the hand by the speed sensor,
acquiring a first frequency of hand tremor motion, wherein the first frequency is the frequency of original human hand tremor motion before applying tremor suppression strategy to a human hand, and a model F (t) ═ C Sin (2 pi n t) + noise (t) + A (t) is taken as a kinematic model of the human hand tremor motion and approximates to a periodic positive selection motion doped with a noise signal, wherein F (t) represents hand motion displacement; t represents a time signal; sin (2 π n t) represents a tremor signal with a period of n; noise (t) represents the tiny disturbance in the process of hand movement and the noise in the process of signal acquisition, and is treated as white noise; a (t) represents a normal motion signal of the human hand, which is a low-frequency signal and is approximately processed by a constant value.
The process of inhibiting the hand tremor signal is essentially a process of filtering a high-frequency signal of a mechanical wave, and simply achieves the purpose of reducing the frequency and the amplitude by applying a certain external moment of inertia.

The acceleration sensor is used for collecting hand motion signals, and the sampling frequency of the acceleration sensor is more than 30 times per second, so that the requirement of the system for frequency domain feature processing is met.
S2, judging whether the first frequency is lower than the threshold value, if yes, ending, if no, going to step S3;
in order to prevent the system from inhibiting the normal movement signal, the movement signal of the hand is detected by the acceleration sensor, and when the system detects that the movement signal is mainly the normal movement signal, the tremor inhibition signal is not generated.
According to the existing data base, the severity of human hand tremor is divided into slight tremor and severe tremor, wherein the tremor frequency of the slight tremor is between 3Hz-5Hz, and the tremor frequency of the severe tremor is between 6Hz-11 Hz. If the threshold is set at 3Hz or a value below 3Hz, the tremor suppression signal may not be generated.

During the movement of the hand, applying a natural frequency moment of inertia I perpendicular to the hand surface, wherein I w/r is-m dx/dt, and m represents mass and is constant; x represents a displacement; t represents time; r represents the motion radius of hand motion, and takes an arm or a wrist as the motion radius; w represents the rotational angular velocity of the hand movement during the rotational movement with radius r.

And the estimated value and the measured value are used as input, the optimal value is calculated by using a Kalman filter and is used as the input of a PID filter, and therefore the stability design of the control system is realized. Systematic errors and noise signals can affect the gain of the Kalman filter in the optimization estimation process.

If the tremor frequency is divided into six gears between 3Hz and 11Hz, the corresponding first tremor suppression signals are different between each gear, but each gear corresponds to a specific first tremor suppression signal, the step realizes that the gears corresponding to the frequency of different hand tremor motions generate the first tremor suppression signals to the human hand based on the PID controller.

and S3, generating a corresponding first tremor suppression signal based on the first frequency, and providing a force opposite to the hand tremor motion to the hand based on the first tremor suppression signal so as to suppress the hand tremor motion.
7. The method of suppressing hand tremor motion of claim 6, further comprising:
s4, obtaining an estimated value and a measured value of a second frequency of hand tremor motion;
s5, acquiring a third frequency through a Kalman filter based on the estimated value and the measured value of the second frequency;
s6, judging whether the third frequency is lower than the threshold value, if yes, ending, if no, going to step S7;
and S7, generating a corresponding second tremor suppression signal based on the third frequency, and providing a force opposite to the current hand tremor motion to the hand based on the second tremor suppression signal so as to suppress the hand tremor motion.
8. The method of suppressing hand tremor motion of claim 7, further comprising dividing the frequency range of hand tremor motion into a number of steps, and wherein said generating a corresponding first tremor suppression signal based on said first frequency comprises said determining the step corresponding to said first frequency based on which the corresponding first tremor suppression signal is generated.
9. The method for suppressing tremor of the hand of claim 8, wherein said step S7 includes:
s71, judging whether the third frequency and the first frequency belong to the same gear, if so, the second tremor suppression signal is the same as the first tremor suppression signal; if not, go to S72;
and S72, judging a gear corresponding to the third frequency, generating a corresponding second tremor suppression signal based on the gear, and providing an acting force opposite to the current hand tremor motion to the hand based on the second tremor suppression signal to suppress the hand tremor motion.
10. A method of suppressing tremor movement of the hands according to any of claims 6-9, in which the first tremor suppression signal is a moment of inertia perpendicular to the natural frequency corresponding to the human hand surface.
11. A method of suppressing tremor movement of the hands according to any of claims 7-9, in which the second tremor suppression signal is a moment of inertia perpendicular to the natural frequency corresponding to the human hand surface.
