Tilt angle sensor-based heart rate detection device and detection method thereof

Abstract

The invention provides a tilt angle sensor-based heart rate detection device and a detection method thereof, and relates to the technical field of heart rate detection. The detection device comprisesa sensor, an analog-to-digital converter, a controller, and a data transmission module which are connected sequentially, and also comprises a power supply module which is connected with the sensor, the analog-to-digital converter, the controller, and the data transmission module, wherein the sensor is a high-precision tilt angle sensor. The detection method comprises the following steps: collecting AD signals, namely placing the controller with the high-precision tilt angle sensor at the heart to collect signals and convert the signals by the analog-to-digital converter; performing amplifying,DC blocking and filtering on the converted signals by the controller to obtain discrete heart impulse signals; calculating and counting adjacent pulse interval sequences of a plurality of cycles; counting and calculating the cross-correlation of the adjacent pulse interval sequences of the cycles; counting the cycles of the adjacent pulse interval sequences with the high correlation and calculating the mean; and calculating to obtain the heart rate value.

Description

technical field [0001] The invention relates to a heart rate detection device based on an inclination sensor and a detection method thereof, belonging to the technical field of heart rate detection. Background technique [0002] With the improvement of living standards, more and more people suffer from cardiovascular disease, so people pay more and more attention to their own health. Cardiovascular disease has become one of the common diseases that threaten human health in contemporary society. Controlling the morbidity requires long-term monitoring of cardiovascular physiological information of patients. Heart rate is one of the most important physiological parameters of the human body. The speed of the heart rate can reflect the state of the body's blood circulation. Heart rate has important applications in the detection and prevention of cardiovascular diseases and in controlling the incidence of cardiovascular diseases. [0003] Heart rate refers to the number of times...

Problems solved by technology

The first two methods are costly, bulky, and inconvenient to wear. Long-term use will increase the user's physical and psychological discomfort.

At present, the widely used method is photoelectric volumetric method, but this method requires the sensor to be closely attached to the human skin tissue, and the accuracy of the data cannot be guaranteed when it is worn improperly, the human body sweats or is disturbed by other external environments
