Abstract

A beacon-based indoor worker emergency rescue system comprises multiple beacons, an emergency control server, an emergency button device, a mobile communication terminal, and a central server. Multiple beacons are distributed and installed within a building, and each transmits electromagnetic waves of a certain intensity containing a unique beacon ID. The emergency control server manages emergency rescue for multiple workers performing tasks within the building. The emergency button device is carried by a worker and transmits an SOS signal when the SOS button is pressed. The mobile communication terminal is carried by a worker and is paired with the emergency button device to perform short-range wireless communication. Upon receiving an SOS signal, it measures the intensity of the electromagnetic waves transmitted from each of the multiple beacons to determine the RSSI, selects a predetermined number of beacons from the multiple beacons in order of highest RSSI, and then generates and transmits an SOS event packet containing pairs of Beacon IDs and RSSIs corresponding to the selected beacons, as well as an SOS event ID. When the central server receives an SOS event packet, it determines the rescue location of the worker based on the pairs of beacon IDs and RSSIs included in the SOS event packet, and transmits an emergency rescue signal containing the rescue location to the emergency control server.

Description

Beacon-Based Indoor Worker Emergency Rescue System and Method The present invention relates to a system capable of providing emergency rescue when an emergency or critical situation occurs to an indoor worker, and more specifically, to a beacon-based indoor worker emergency rescue system and method capable of providing emergency rescue by using a beacon to quickly and accurately identify the location of an indoor worker in an emergency or critical situation. As modern industrial sites, logistics warehouses, and the interiors of large buildings become increasingly vast in scale, it is becoming increasingly important to quickly locate and rescue workers in the event of emergencies or critical situations at these sites. Generally, it is possible to identify a worker's location via GPS in outdoor environments, but in indoor work environments, GPS signals are blocked, making it impossible to determine the worker's location using GPS. Conventionally, to track the location of a worker in an indoor environment, a system is known that establishes a sensor network indoors and tracks the worker's movement path in real time through multiple sensors. However, this has the disadvantage of not only requiring the construction of expensive infrastructure such as sensor networks, but also raising issues regarding privacy or personal information protection because the location and movements of workers are tracked in real time. Therefore, there is a need for an emergency rescue system that can quickly and accurately locate indoor workers in emergency situations and perform rescues without building expensive infrastructure, while also avoiding issues regarding the infringement of workers' privacy.
