Teeth clenching signal acquisition method and electronic equipment control method and device

Abstract

The present invention provides a method and device for obtaining teeth clenching signals and a control method and device for electronic equipment. The device is easy to carry and wear. The method includes the following steps: S1, receiving brain wave signals collected by a brain wave collecting device; S2, Perform Fourier transform on the brain wave signal to obtain the frequency domain signal of the brain wave signal; S3, in the frequency domain signal, calculate the average value of the signal amplitude within a specific frequency range; the average value is used as the teeth clenching signal value. According to the actual measurement results, this algorithm can effectively detect teeth clenching in real time, and can conveniently and effectively control the triggering of other products, freeing hands. Integrating into electronic equipment, it can realize more diversified functions, and can also control services such as making calls, asking for help, and calling the police, as well as controlling the power on and off.

Description

technical field [0001] The invention relates to the field of electronic and bioelectrical information extraction, in particular to a method and device for acquiring a tooth clenching signal and a control method and device for electronic equipment. Background technique [0002] In recent years, the development of control technology for electronic equipment using human bioelectricity has provided more possibilities for the liberation of human hands and the automatic control of electronic equipment. [0003] Bioelectricity includes brain electricity (also known as brain waves), myoelectricity and so on. Traditionally, these signals have been acquired using bulky instruments, making it difficult for large-scale applications in personal consumer electronics. [0004] The Chinese patent with the patent number of 201220129712.X and the title of "Head-mounted EEG Detector" and its series of subsequent improvement patents propose some miniaturized EEG detectors that are easy to carr...

Problems solved by technology

[0006] But in the prior art, the acquisition method of teeth clenching signal is not ideal yet

For example, in the patent document CN201110031304, it is to collect and process the myoelectric signal of the temporal muscle position of the head when clenching the teeth, and the acquisition electrode is relatively complicated and needs to wear a helmet or an EEG collection cap; action, but the installation position of its brain electrodes adopts the international 10-20 standard electrode system distribution, which is only suitable for use in hospitals and laboratories; in the patent document CN201811535827, it uses an electroencephalograph, which obviously cannot be portable and wear
