Description

REAL-TIME GUIDANCE SYSTEM FOR EARTHQUAKE EVACUATION AND ITS OPERATION METHOD Field of the Invention < RTI ID = 0.0 >

The present invention relates to a real-time guidance system for earthquake evacuation and an operation method thereof, and more particularly, to a real-time guidance system for earthquake evacuation and an operation method thereof for evaluating a danger level in an earthquake occurrence and guiding the evacuation route quickly.

Urbanization has been going on recently, artificial underground and indoor structures are becoming larger, and the structure is getting complicated. Therefore, when there is a disaster such as an earthquake in the inside of such a large structure, it is difficult to evacuate quickly out of the structure.

Therefore, in recent years, a technology has been developed to guide a route that can evacuate quickly and safely when a disaster occurs. However, the conventional technology was a level that not only recognized the occurrence of a disaster such as an earthquake, but also guided the route to escape at the shortest distance from the current position.

However, in the event of an earthquake or other disaster, the route of escape at the shortest distance may be more dangerous due to the various risk factors inside the structure. For example, if a gas pipeline is broken due to a disaster in the path leading to the shortest distance, gas is flowing out, or a problem occurs with dangerous factors such as explosion or leakage of combustible material, If you guide the evacuation route, there is a risk of a larger accident.

Therefore, in case of disaster such as earthquake, it is necessary to provide a technique that can guide the route that can escape safely and quickly in real time.
