Embodiment 1

[0067] figure 1 This is a flowchart of a heart rate detection method provided in the first embodiment of the present invention. This embodiment is applicable to heart rate detection. The method can be executed by hardware equipped with corresponding software and specifically includes the following steps:

[0068] Step S110: Obtain the current pressure value of the airbag, and obtain the collected heart rate value matching the current pressure value; the side of the airbag one is fixedly connected to the detection system or the detection device body, and the other side is close to the skin of the human body, and the pressure value of the airbag is actually The upper detection system or the time pressure value of the detection device body on the human body surface. The detection system or the detection device may adopt the sound pressure detection method to obtain the collected heart rate value.

[0069] Furthermore, the skin on the surface of the human body can be the skin correspon...

Embodiment 2

[0079] Normally the human body is in a normal state, and the heart rate changes slowly and is in a relatively stable state. When the human body is in motion, the heart rate changes rapidly, and the heart rate signal is important for the user to judge whether the human body can continue to exercise in the current state. Therefore, the acquisition frequency of the heart rate value under exercise is greater than the frequency acquisition in the normal state, and the frequency acquisition in the exercise state is usually real-time acquisition. But the power consumption of real-time acquisition will be very large.

[0080] As a further preferred embodiment, in the above-mentioned heart rate detection method, in step S110, obtaining the current pressure value of the airbag and obtaining the collected heart rate value matching the current pressure value further includes:

[0081] Step S1101: Pre-make a collection of heart rate cut-off values;

[0082] Step S1102, determine whether the curr...

Embodiment 3

[0087] When the human body is in motion, the detection system or the detection device body and the human skin surface move relative to each other, and sometimes the pressure value may be momentarily low, and then a false alarm may occur, in order to overcome this defect.

[0088] As a further preferred embodiment, in the above-mentioned heart rate detection method, in step S130, issuing an alarm in a state where the pressure value matches the pressure invalid threshold signal includes:

[0089] Step S1301, in a state where N pressure values ​​matching the pressure invalid threshold signal are continuously obtained within a predetermined time, determine that the current collected heart rate value is invalid;

[0090] Step S1302, issue the alarm.

[0091] The alarm signal will be sent out only when the N pressure values ​​matching the pressure invalid threshold signal are continuously obtained to avoid false alarms.

[0092] As a further preferred embodiment, where N is a positive integer...

Abstract

The embodiment of the invention relates to the detection technique, and particularly relates to a heart rate detection method and a heart rate detection system. The heart rate detection method comprises the following steps of detecting a current pressure value, judging effective contact between the detection system and the body surface skin through the pressure value, and calculating to form a heart rate signal output in the state of effective contact of the detection system and the body surface skin. On one hand, when the ineffective contact between the detection system and the body surface skin is judged, an alarm is given to remind a user that the current acquisition is ineffective, the detection system needs to be correspondingly regulated to acquire the effective acquisition; and on the other hand, calculation is implemented according to the pressure value, an acquired heart rate value and a standard pressure value to form the heart rate signal output, the condition of inaccuracy of the outputted heart rate signal, caused by the relatively low pressure formed by the detection system on the body surface skin, is avoided, and the method aims at improving the detection accuracy of the heart rate signal.

Description

Technical field [0001] The embodiment of the present invention relates to detection technology, and in particular to a heart rate detection method and system. Background technique [0002] Heart rate refers to the number of times the human heart beats per minute. In the detection of human parameters, the heart rate is a very important physiological index, which provides a reference for medical diagnosis. At the same time, heart rate can also be used as an objective evaluation index of the physiological load of human exercise, and has been widely used in various aspects of fitness exercises and competitive sports training. At present, heart rate monitors still have many limitations. Finger clip heart rate monitoring requires the subject to remain still during the measurement. ECG electrode heart rate monitoring requires electrodes to be attached to a fixed position on the skin to monitor heart rate, which is difficult to meet future electronic health monitoring, wearable devices ...
