AI Technical Summary

Technical Problem

In traditional technologies, electrocardiogram data, heart sound data, and brachial artery pressure data are usually collected using separate devices, which cannot achieve high-precision synchronous acquisition.

Method used

By acquiring a constant pressure value from the arm cuff, and using timer interrupts and inline assembly instructions, the synchronous operation of the ECG measurement module, heart sound measurement module, and blood pressure measurement module is controlled, ensuring that the acquisition time interval between each module is controlled within the nanosecond level error.

Benefits of technology

It achieves high-precision synchronous acquisition of electrocardiogram data, heart sound data, and brachial artery pressure data, improving the reliability and accuracy of data acquisition.

Abstract

The application relates to a data collection method and device, computer equipment and a computer readable storage medium. The method comprises the following steps: in response to a timer interrupt instruction, entering a timer interrupt program, starting a clock counter and recording an initial count value; in the timer interrupt program, starting an electrocardiogram measurement module, a heart sound measurement module and a blood pressure measurement module according to a preset order according to preset assembly instructions, and measuring state data corresponding to a user; when the current count value of the clock counter reaches a threshold value, closing the electrocardiogram measurement module, the heart sound measurement module and the blood pressure measurement module according to the preset order based on the corresponding assembly instructions to obtain a target data set; based on the initial count value and the current count value, a data collection duration is obtained, and based on the target data set and the data collection duration, target state data is obtained. The method can realize high-precision synchronous collection of electrocardiogram data, heart sound data and brachial artery pressure data.
