s304: and 4, step 4: the Bluetooth transmitting circuit 505 converts the distress signal sent by the 2541 chip 503 into a Bluetooth 2.4GHz radio signal and transmits the signal to the smart phone 6;
s305: and 5: the bluetooth receiving circuit 605 of the smart phone 6 receives the radio signal and converts the radio signal to obtain a distress signal;
s306: step 6: after the bluetooth receiving circuit 605 transmits the distress signal to the mobile phone master control 603, the mobile phone master control 603 sends a reminding signal to the display screen circuit 601;
s307: and 7: after the display screen circuit 601 receives the reminding signal sent by the mobile phone master control 603, the middle display area of the display screen circuit 601 displays an alarm image to remind a baby guardian;
s308: and 8: after the infant guardian receives the alarm image displayed in the middle display area of the display screen circuit 601 of the smart phone 6, the infant guardian slides the touch screen circuit 602 to indicate that the infant guardian has received the alarm prompt of the smart phone 6, the infant guardian acts on the touch screen circuit 602, and the touch screen circuit 602 transmits a user feedback signal to the mobile phone main control 603;
s309: and step 9: after the mobile phone master control 603 receives the user feedback signal transmitted by the touch screen circuit 602, the mobile phone master control 603 stops sending the reminding signal to the display screen circuit 601;
s310: step 10: after the display screen circuit 601 does not receive the reminding signal sent by the mobile phone main control 603, the display screen circuit 601 stops sending the alarm image.
The monitoring system and the method for preventing the baby from turning over and suffocating provided by the embodiment 3 can timely find that the baby turns over or kicks off a quilt, timely remind a baby guardian of paying attention to dangerous conditions, and avoid harming the baby.
