1.1 Summary of Design Requirements
According to the requirements, it is required to design a human health monitoring system based on STM32. The idea of system modularization is adopted, and the data and operation instructions collected by multiple digital-analog sensors are sent to the STM32 central processor for processing and analysis.
The system can monitor the subject's heart rate, body temperature and the temperature of the surrounding environment in real time, and can also judge whether the subject is sleeping through posture calculation. The system can display the heart rate, body temperature and other data of the subject not only locally, but also through WI-FI to the cloud platform for remote display. When the subject smokes, an alarm will be issued until the cigarette is extinguished, which can keep the subject away from unhealthy living habits, and at the same time, the location of the device can be checked through satellite positioning.
All the data collected by the above sensors can be uploaded to the cloud platform built by ourselves, and real-time display demonstration and analysis can be performed on the cloud platform or on the mobile APP designed by ourselves. Make the data display intuitive and beautiful and convenient. The positioning function can directly display the detailed information of the map in real time.
Function summary:
(1) Can detect human body temperature
(2) Can detect ambient temperature and humidity
(3) Can obtain current GPS positioning data
(4) The data can be uploaded to the Huawei Cloud IoT platform through WIFI, and the data of each sensor can be displayed remotely on the mobile APP designed by ourselves.
(5) Can detect whether smoking
(6) Each sensor data can be displayed on the local LCD display
(7) Can detect heart rate, blood oxygen, and judge the health status of the human body through heart rate, blood oxygen and body temperature
(8) Can detect human posture,
