Abstract

Most of the traditional fire evacuation systems present today are designed on the assumption that the people present in the building have prior knowledge about the nearest safety exits, but this assumption is not true in many cases and has also resulted in the loss of life in several instances. The Automated Fire Evacuation System is an embedded system which will effectively guide the victims of fire accidents to nearest safety exits. A network of temperature and smoke detector sensors placed strategically collects and delivers accurate information about the surroundings to the system. The Dijkstras algorithm is used to calculate the safest and shortest path to the exits. The evacuation path generated is conveyed to the victims through the use of LED strips which glows in a unidirectional pattern. The system also has an additional congestion control feature which uses image processing to detect congestion of corridors, if any congestion is detected the algorithm dynamically reroutes the people to other available evacuation paths.
