Dynamic Evacuation System for the Intelligent Building Based on Beacons and Handheld Devices

Abstract

Mobile evacuation routing in a smart building offers a great opportunity to evacuate buildings more efficiently and safely compared to the most commonly used evacuation systems (static mounted evacuation signs). Our system is based on the mobile operating system Android and the cross-platform game engine Unity. Beacons were used for indoor localization. The app reacts to emergency situations and guides people safely out of the building. Based on the current position and the position of the hazard, the system detects blocked escape route sections and bypasses them. Static obstacles can be added and are taken into account in the escape route calculation. The user can see the building plan, the escape route, the danger, and the current position during evacuation.
