Abstract

The invention discloses a respiratory frequency detection method including the steps: acquiring a distance change signal of at least one mark position in a human chest in a preset acquisition period;carrying out normalizing treatment of the distance change signal to obtain normalized data; filtering the normalized data to obtain a first respiratory signal; and carrying out wavelet transform of the first respiratory signal to obtain a second respiratory signal, and determining the respiratory frequency according to the second respiratory signal. By recording the fluctuation change of a specific area of the human chest, the distance change signal is transformed into the respiratory signal, and the respiratory frequency is obtained by processing the original signal with combination of normalization, filtering and wavelet transform technologies. The method has the advantages of high signal acquisition real-time capability, accurate and reliable calculation results and simple detection operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a breathing frequency detection method, device, storage medium and computer equipment. Background technique [0002] In the prior art, the means of monitoring respiratory conditions are generally detected by contact sensors, which require installation and connection of the sensors, which is inconvenient to use. In the contact sensor detection scheme, it includes wired and wireless connection methods. For example, a wireless breathing monitoring device disclosed in the prior art includes a control circuit, a piezoelectric film sensor and an antenna, and the control circuit is electrically connected to the piezoelectric film sensor and the antenna respectively. , the piezoelectric film sensor is used to sense the respiratory movement and convert it into a corresponding charge signal, which is processed by the control circuit to obtain the corresponding monitoring result, ...
