Embodiment

[0042] as per Figure 4 The prototype of the embodiment of the invention shown was tested. Among them, such as figure 1 As shown, the bruxism monitoring and detection equipment provided by the present invention adopts surface electromyography electrode monitoring equipment, including surface electromyography electrode 1, signal processing module 2, storage module 3, MCU4, power supply module 5, LCD display 6.

[0043] The surface electromyography electrode 1 will quickly and stably obtain the electrical signal on the skin surface, and send the electrical signal to the signal processing module 2; there are 3 surface electromyography electrodes on it, one as a reference ground, and the other two as a reference ground. Acquire and output the skin surface EMG signal.

[0044] The signal processing module 2 filters and processes the electric signal transmitted from the surface electromyography electrode, and then amplifies it through the amplifier;

[0045] The 12-bit ADC that com...

Abstract

The invention discloses a system and method for surface electromyogram signal feature recognition of bruxism. Electromyographic signals on the surface of masticatory muscle skin is obtained quickly and stably through a surface myoelectricity electrode, the obtained signals are subjected to preliminary amplification and filtering through a designed signal processing module, the signals are sent to an MCU, an ADC which the MCU is provided with is used to perform analog-digital conversion and software filtering processing on obtained analog signals, the processed signals are subjected to digital filtering processing and algorithm analysis to identify whether masticatory muscles perform activity of grinding one's teeth and displaying surface myoelectricity waveform of the masticatory muscles, and thus values of surface electromyogram signals and waveform information are obtained. The system has functions of real-time display of masticatory muscle surface electromyogram signals and real-time waveform monitoring, surface electromyogram signal data storage and surface electromyogram signal identification, bruxism patients can be monitored precisely and stably, and feature recognition on bruxism electromyographic signals is performed.

Description

technical field [0001] The invention belongs to the technical field of signal recognition, and in particular relates to a surface electromyography signal feature recognition system and method for bruxism. Background technique [0002] Bruxism (Bruxism) refers to the unconscious grinding or clenching behavior of the upper and lower teeth when a person is sleeping or awake, and the grinding of the teeth is often accompanied by a "creaking" sound. And because it mostly occurs during sleep at night, it is also called night bruxism. People are in the teeth replacement period from 6 to 13 years old, and there will be teeth grinding in order to adapt to the grinding of the upper and lower teeth. However, if adolescents and adults who have passed the teeth-changing period often have teeth grinding, it is a kind of sickness. Bruxism has certain damage to the human body. The direct harm of bruxism is the loss of tooth tissue. Bruxism can easily cause human maxillofacial and proximal...
