Abstract
As the number of elderly and sub-healthy people increases, people need systems that can monitor their health in real time. As an emerging communication technology, Narrowband Internet of Things (NB-IoT) technology has the characteristics of super coverage, massive connections, and low power. In this paper, we designed a human health monitoring system based on NB-IoT technology. Mainly completed the following work: 1) We designed a terminal device containing STM32 microprocessor to collect pulse, body temperature and geographical location. 2) Combined with the existing NB-IoT network, we built a Tomcat server in the cloud to stored the uploaded information in the MySQL database. We designed the alarm service. In an emergency, the system will send the GPS location information of the user to the set caregiver by mail. 3) We designed a web application. A doctor or family member can use the web page to view a line chart of past data. The experimental results show that the designed human health monitoring system can realize the function of real-time monitoring.
