Development of indoor positioning application for rescue based on bluetooth low energy beacons

The assistance of indoor positioning is very important for rescue. If the location information of people in the indoor space is detected, the spatial disorientation of the rescue personnel greatly reduces. The concept of this system is to design a fingerprint indoor positioning system with BLE (Bluetooth Low Energy) technology in order to achieve stable positioning in anticipation of the needs of rescuers. The proposed system uses mobile phones as the application platform, which is convenient for rescuers to carry around. The user's location is displayed on the mobile device screen along with the building plan. The application has a compass function that shows the user's orientation on the building plan to provide the user with accurate information about the space for rescue and escape. We expect to provide more diverse solutions for indoor positioning and indoor rescue in the future.
