Abstract: Blood pressure detection signal sampling and compensation methods and apparatuses, and an example blood pressure signal collection system are described. One example method described includes controlling an electrocardiogram (ECG) sampling module and a photoplethysmogram (PPG) sampling module to simultaneously sample a standard periodic signal. Sampling frequencies and sampling end times are separately obtained. A sampling start time and a sampling frequency of the ECG sampling module or the PPG module is then compensated so that a sampling frequency deviation is less than a preset frequency threshold and a sampling end time difference is less than a preset time threshold.

Abstract: The present disclosure relates to blood pressure calibration period determining methods and devices. One example method includes obtaining, by a blood pressure measurement device, first physiological status information and second physiological status information of a tested person, where the first physiological status information is related information that causes a change in blood pressure of the tested person within a first time period after the blood pressure is calibrated, and where the second physiological status information is related information that causes a change in the blood pressure of the tested person within a second time period before the blood pressure is calibrated, and determining, by the blood pressure measurement device, a blood pressure calibration period based on a degree of change of the first physiological status information relative to the second physiological status information.

Abstract: A stress evaluation and calibration method and apparatus, and a storage medium are disclosed. The stress evaluation and calibration method includes: obtaining a physiological parameter signal of a user; determining a smallest stress state value of the user within preset duration based on an eigenvalue vector of the physiological parameter signal and a stress evaluation system; determining calibration information based on a smallest reference stress value of a group to which the user belongs and the smallest stress state value; and calibrating, by using the calibration information, a stress state value output by the stress evaluation system, to determine a theoretical stress state value of the user. With the stress evaluation and calibration method and apparatus, a stress evaluation result can be automatically calibrated, to improve evaluation accuracy, and active participation of the user is not required, to improve user experience.
