Design of harmony OS-based IOT system for wearable health monitoring

In this work, an internet of things (IOT) system is designed for wearable health monitoring based on the Harmony operation system (OS). The BearPi-HM_Nano and Arduino Uno development boards are used as the main control units for collecting the signals from multiple sensors, reading the near field communication (NFC) card and excuting interaction through voice broadcasting and LEDs. The Harmony OS is run on the BearPi-HM_Nano boards to read the sensors via APIs and schedule multiple tasks. The WiFi transmission is adopted using the build-in WiFi modules on the BearPi-HM-Nano boards. The web A dedicated server is constructed for the IoT system and run remotely on the Alicloud computing platform. The web front end and wechat applet are desiged to interact with users. As for the functions, the system can be used for patients' remote monitoring of life indicators of themselves and their families, online diagnosis and treatment, intelligent generation of golden health code, disease prediction, generation of electronic health cases, etc.
