Problems solved by technology

[0002] Cranial cavity vibration can promote the exchange of metabolic products between brain tissue and cerebrospinal fluid, and can speed up the renewal rate of cerebrospinal fluid. However, under the matching of resonance frequency, the energy of cranial cavity resonance is very weak, and the weak vibration interference in the air is usually stronger than the resonance of the cranial cavity. The existing technology cannot realize the detection of the vibration of the external cranial cavity of the human brain

Abstract

The invention belongs to the signal processing technical field and provides a cranial cavity vibration detection method and device. The method includes the following steps that: vibration signals to be detected are acquired, and filtering processing is performed on the vibration signals, and Fourier transform is performed on the filtered vibration signals, and as a result, a frequency domain image of the vibration signals can be obtained; the largest energy value and the second largest energy value within cranial cavity vibration effective bands in the frequency domain image are obtained; and the vibration signals are determined as cranial cavity vibration signals when the largest energy value and the second largest energy value satisfy preset cranial cavity vibration conditions. With the cranial cavity vibration detection method and device of the invention adopted, detection of cranial cavity vibration can be realized, and the accuracy of cranial cavity vibration detection can be improved.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a cranial cavity vibration detection method and device. Background technique [0002] Cranial cavity vibration can promote the exchange of metabolic products between brain tissue and cerebrospinal fluid, and can speed up the renewal rate of cerebrospinal fluid. However, when the resonance frequency is matched, the energy of cranial cavity resonance is very weak, and the weak vibration interference in the air is usually stronger than the resonance of the cranial cavity. The existing technology cannot realize the detection of the vibration of the external cranial cavity of the human brain. Contents of the invention [0003] In view of this, embodiments of the present invention provide a cranial cavity vibration detection method and device, so as to realize cranial cavity vibration detection and improve the accuracy of cranial cavity vibration detection.
