In this embodiment, the processing module has an myoelectricity processing unit and a singlechip, and the myoelectricity processing unit has an amplifier and a filter, and is used for amplifying and filtering the collected myoelectricity signal through the amplifier and the filter.

The amplifier may be a low noise programmable PGA202 gain amplifier, which may enable amplification of weak signals.

The filter filters one or several harmonic waves by using a capacitor and a reactor to form an LC resonant circuit, and can effectively inhibit noise (especially power frequency interference).

If the surface electromyographic signals of the muscles exceed the set value for 10 seconds, a warning is sent out to remind the wearer of correcting sitting postures.

In this embodiment, one end of the conductive buttons 55, 56, 57 is connected to the angular velocity sensor through a shielding wire, and the other end is connected to the processing module through a conductive button at the bottom of the controller. If the sitting posture of the wearer is poor, when the body is bent or inclined, the spatial coordinates of the angular velocity sensors positioned at the shoulders and the waist are changed to generate corresponding displacement, and if the displacement of the angular velocity sensors exceeds a set value for 10 seconds, a warning is sent out to remind the wearer to pay attention to correcting the sitting posture.

In the case of large differences in body posture, the number of muscle fibers that the muscles need to mobilize is different. When the sitting posture is normally relaxed, the cervical muscle and the waist muscle are passively pulled, but the cervical muscle and the waist muscle are slightly contracted to a small extent, so that the spinal curvature is maintained, and when incorrect states such as curvature or inclination are caused, the active contraction amplitude of the cervical muscle and the waist muscle is increased, the muscle activity is enhanced, and the myoelectricity amplitude is larger than the relaxation position, so that the amplitude of the myoelectricity signal is used as a judgment basis, and the condition that the sitting posture of a wearer is poor can be determined.

After the power is turned on, when the sitting posture of the wearer is bad, the active contraction amplitude of the trapezius muscle or the erector spinal muscle is increased, the activity of the muscle is enhanced, and accordingly, the amplitude of the surface electromyographic signal of the muscle is increased, if the surface electromyographic signal of the muscle is always higher than the previous value and exceeds the set value for 10 seconds, the processing module controls the loudspeaker 502 to send out a warning message, for example, "you have too far left body, please correct in time", and the like. The sitting posture state of the wearer can be clearly indicated, and the wearer can clearly and quickly correct the sitting posture.

When the body of the wearer bends or tilts, the spatial coordinates of the angular velocity sensors located at the shoulders and waist change, corresponding displacement is generated, the displacement of the angular velocity sensors exceeds a set value for 10 seconds, and the processing module controls the loudspeaker 502 to send out a warning message to remind the user to correct the sitting posture.
