摘要：
The present invention relates to an infant and child safety monitoring system using a wearable device based on a smart phone. The present invention relates to an infant and child safety monitoring system using a wearable device based on a smartphone including a wearable device 100 in a band form and a smartphone 200, An SpO2 sensor 110 in which a light emitting (IR / Red LED) element and a photo-diode sensor are packaged for reflection type measurement； A constant current LED switching unit 120 for driving the LED of the SpO2 sensor 110； A Bluetooth module 140 for Bluetooth communication with the smartphone 200； An MCU 160 for processing SpO2, pulse rate detection, posture detection, and communication execution from the measurement signal by the SpO2 sensor 110； And a three-axis acceleration sensor 170 for detecting only a supine position and a prone position in a posture in which the rotational angle is obtained using the gravitational acceleration direction projected on each axis； The firmware of the MCU 160 extracts the AC / DC component of the signal by applying a digital LPF for noise removal and a QV algorithm for baseline detection in the SpO2 and pulse rate detection processes, and the acceleration sensor And transmits the SpO2, pulse rate, and attitude information to the smartphone 20 through the Bluetooth module 140. [ Thus, it is possible to provide oxygen saturation and attitude monitoring in real time for prevention of sudden infant death through band type wearing device and monitoring application. In addition, the present invention can detect the oxygen saturation and the posture in real time by wearing a band-type wearable device on the thighs (thighs) of infants and young children and automatically transmit the detection information to the smartphone through Bluetooth, While the guardian can easily check the infant condition information. In addition, the present invention displays an oxygen saturation and posture received from a wearable device in re
