Problems solved by technology
However, most oximeters simply measure the blood oxygen content and do not have the ability of remote monitoring. Especially for the elderly who are alone at home, they can measure the blood oxygen content and heart rate and notify themselves in time. Family members, it is particularly important for family members to grasp their physical condition in the first place

The invention discloses a GSM-based human body remote blood oxygen heart rate monitoring system and method. The method comprises the following steps of alternatively emitting red light and infrared light from a light emission module by adopting a time division multiplexing mode, wherein the red light and the infrared light are attenuated after penetrating through fingers; through a light-frequency conversion module, converting the transmitted light into a corresponding electric signal and transmitting the electric signal to a controller; forming a pulse signal after the controller captures the received electric signal; calculating a heart rate by utilizing changes of a jump edge in the captured pulse signal, and sending a short message by virtue of a GSM module; denoising the collected pulse signal by utilizing a wavelet threshold denoising method; carrying out non-linear threshold processing on wavelet coefficients; reconstructing the signal by utilizing the denoised detail signal and a smoothing signal; and resolving oxygen saturation by utilizing the reconstructed signal, and sending short messages by virtue of the GSM module.
Description
technical field [0001] The invention relates to the technical field of blood oxygen heart rate monitoring, in particular to a GSM-based human body remote blood oxygen heart rate monitoring system and method. Background technique [0002] During blood circulation, when the ventricle contracts and the aortic valve opens, blood is injected into the aorta. Due to the resistance of the vascular system, this part of the blood cannot be discharged into the vein immediately, so that the blood injected into the aorta temporarily stays in the aorta Proximal, and cause aortic dilation and pressure increase. When the ventricles relax, the aortic valve closes, and the ejection stops, the aorta will contract due to the recovery of elasticity. When the aorta expands and contracts, the pressure will spread from the elevated area to the distal end of the aorta and its branches in the form of waves, and the arteries will fluctuate visible to the naked eye. Thus, a pulse waveform that includ...
