Method, device and equipment for controlling self-adaptive pressure relief speed of electronic sphygmomanometer

The invention relates to the technical field of medical instruments, and discloses a method, device and equipment for controlling the self-adaptive pressure relief speed of an electronic sphygmomanometer, and the method comprises the steps: continuously collecting pulse oscillation signals in the pressurization process, and recording the time and amplitude of a wave crest signal until pressurization is finished; the time and the amplitude of the wave crest signal are converted into pulse rate data, the aggregation center of the pulse rate data is searched through a clustering algorithm, the dispersion degree of the pulse rate data is calculated, whether arrhythmia exists or not is judged accordingly, and the optimal pulse rate is calculated; and the optimal pressure relief speed is calculated according to the optimal pulse rate, the current pressure relief speed is continuously obtained to serve as an input value, the optimal pressure relief speed serves as a target value, and the electronic pressure relief v
