1. Design requirements
1.1 Project Background
Since the 21st century, with the development of science and technology, the problem of China's aging population has become increasingly serious while people's living standards have been continuously improved, coupled with the development of social economy. Many children go out to work, making more and more empty-nesters unable to receive timely and effective care and treatment. Therefore, this system takes the elderly as the center, and sets up many related functions to monitor the elderly, making the life of the elderly safer and more convenient.
1.2 Functional requirements
This monitoring system is based on the STM32 single-chip microcomputer to detect the physical status of the elderly in real time through sensors, and after processing and converting the status information, send it to the OneNet cloud platform through the external network. Redesign the visualization page to present the collected information and intelligent analysis to users. In addition, if the status of the elderly is abnormal, the system will automatically respond in time.
The specific functions implemented are as follows:
1. Track the health indicators of the elderly: pulse, heart rate, body temperature;
2. Positioning and tracking the elderly;
3. The system has corresponding alarms for various indicators of the elderly. If an emergency such as an elderly fall occurs, the system will automatically send a set SMS to notify the emergency contact, realizing remote real-time health monitoring of the elderly;
4. The system requires good stability, wearable, convenient and practical;
5. The error of the measured body temperature does not exceed 0.2°C.
The system frame diagram is as follows:
