Design of intelligent quilt based on single chip microcomputer

In order to realize the temperature of the quilt, it can be adjusted locally in real time so that the temperature of the quilt is always at the optimum temperature, And real-time monitoring and analysis of the user's vital signs data, If the analysis finds that the user's vital sign data is abnormal, it can automatically alarm the function. This paper designs a 51 single-chip microcomputer as the main control, Combined with temperature sensor, Heart rate blood oxygen sensor, Semiconductor refrigeration/heater and WIFI wireless communication mode, An intelligent quilt system is designed. The system is controlled by STC89C52RC chip, and receives body temperature data through DS18B20 temperature sensor. Heating or cooling through semiconductor chips, bring it to the preset temperature. At the same time, the heart rate is collected through the heart rate and blood oxygen measurement module, vital signs data such as blood oxygen and degrees, and upload the data to the cloud, Analyze these vital signs data in the cloud, In order to achieve real-time monitoring of human vital signs data. It has been experimentally verified, The system can stabilize the temperature inside the quilt to 37 degrees Celsius, And can stably upload temperature, heart rate, blood oxygen and other vital signs data to the cloud, When the vital sign data is similar to the preset vital sign danger data (for example, the heart rate data is less than 40 beats/min and greater than 120 beats/min), the system will automatically alarm and upload the vital signs to the help unit in real time. The experimental results show that the system can provide a feasible solution for smart home and smart medical care.
