Very important physical signs, provides reference for medical diagnosis.Meanwhile, heart rate also can be as human motion
The objective evaluation index of physiological stress, have been widely used in body building, athletics and physical training each
Aspect.At present, Cardio kickboxing yet suffers from much limiting, and finger-clipped rhythm of the heart needs measured to exist
Measuring and keep static, ECG electrode rhythm of the heart needs electrode slice is affixed on the skin retention device monitoring heart
Rate, it is difficult to meet the requirement of future electronic health monitoring, wearable device etc., extract the most whenever and wherever possible
The heart rate data of people is just particularly important.
In prior art, also there are the record using photoplethysmographic tracing detection heart rate, photocapacitance
The photoelectricity means that are made by long-pending pulse tracing detect a kind of noinvasive of volumetric blood change in biological tissue
Detection method.When the light beam of certain wavelength is irradiated to skin surface, light beam is by by transmission or reflection
Mode is sent to photelectric receiver.In the process, due to the attenuation by absorption by integumentary musculature and blood
Effect, the light intensity that detector detects will weaken, wherein the absorption to light such as skin, muscle, tissue
Whole blood circulation is to maintain invariable, and the volumetric blood in skin under key role in
Pulsation changes.When the heart contracts, external perihaemal canal blood volume is most, and absorbing amount is the most maximum, detection
The light intensity arrived is minimum；And when diastole, external perihaemal canal blood volume is minimum, the light intensity detected
Maximum, the light intensity making photelectric receiver detect changes in pulsating therewith.By this intensity variation
Signal is converted into the signal of telecommunication, just can obtain the change of volume pulse blood.Heart rate can be by telecommunications
Number the rhythm and pace of moving things, the cycle, amplitude analysis calculate obtain.PPG sensor is smaller, is suitable for being embedded into
In wearable device.Therefore, wearable heart rate monitor in real time can by gathering, analyze, process PPG
Signal realizes.But, still suffer from much challenging by processing PPG signal calculating heart rate.Due to PPG
Signal is the bio signal extracted from skin surface, and its signal intensity is weak, be easily disturbed, industrial frequency noise,
The signal quality gathered all can be made a big impact by environment noise, motion artifacts etc., and is difficult to filter out.
Motion artifacts interference is caused by tissue interference, venous blood volume and change in optical path length in motion, due to
The main frequency of motion artifacts can overlap with the frequency of heart rate under many circumstances, in multiple noise,
Most it is difficult to eliminate, uses photoplethysmographic tracing to typically require light source, this mode power consumption simultaneously
Bigger.
