Design and Implementation of Firefighter Signs Monitoring System Based on Internet of Things Technology

With the development of economy, there are more and more buildings and cities are getting more and more crowded, which brings great challenges to firefighting and rescue. While performing search and rescue tasks, firefighters are unable to evacuate accident scenes in time due to factors such as excessive fatigue and dangerous situations, resulting in a great threat to firefighters’ personal safety. Relying on modern high-tech rescue equipment can effectively reduce casualties, so it is very urgent to develop a reliable and safe vital signs monitoring system. Based on the above background, this paper researches and designs a set of vital signs monitoring system for firefighters. The core of the system is a multi-functional wrist watch, with a waist relay module as the information relay component, which can record the firefighter’s heart rate, body temperature, walking steps, air pressure height, compass and Compass positioning in real time and transmit them to the background through Lora communication technology, so that the whole system can monitor the firefighter’s body signs at all times.
