Respiration rate measuring device, method, equipment and medium

The invention discloses a respiratory rate measuring device and method, equipment and a medium, and the device comprises a signal processing module which is used for processing an original pulse wave signal collected at the current moment to obtain a current processed pulse wave signal, and obtaining the maximum value and the minimum value of the signal; the parameter determination module is used for determining the amplitude and the sampling point number of the current processed pulse wave signal; the sequence acquisition module is used for skipping to the step of the signal processing module again to obtain a first amplitude sequence and a first sampling point number sequence; the sequence processing module is used for performing interpolation on the first amplitude sequence and the first sampling point number sequence to obtain a second amplitude sequence and a second sampling point number sequence, and obtaining a current respiratory wave signal sequence based on the second amplitude sequence and the seco
