Description

FIELD OF THE INVENTION [0001] The present invention relates to a three-

FIELD OF THE INVENTION The present invention relates to a system and a method for presenting an optimal path according to a fire occurrence in a three-dimensional manner.

Recently, as the size of the building has increased and diversified, there has been a growing interest in preventive facilities to minimize damages in case of a fire. There is an increasing interest in the safety issues of preventive and countermeasures to prevent the loss of lives and property damage due to fire in buildings.

Accordingly, as technology development and network environment are established, not only fire prevention technology but also building design technology for evacuation has been dramatically developed.

In case of a fire in a building, the evacuator must escape the final exit by himself / herself due to the fire or sound of the building or the perception ability of the building structure due to the fire. In the process of escaping from such a building, the evacuator tries to move to the nearest passage or stairway rather than the shortest distance to the escape hole. Therefore, damages due to toxic gas such as poisonous gas occur more frequently have.

In other words, it is most desirable to attempt to escape in the early stage of the fire to escape, and if the fire progresses, the escape can be succeeded.

However, the conventional route providing technique according to the fire generation provides the safest and quickest evacuation route to induce fire evacuation based on the location of the fire occurrence and the location of the large pizza, so that the type of fire (early, middle or late) There is a limitation that it can not take into account the type (kind depending on the material in which the fire is generated), the diffusion estimation and the degree of gravity (weight), and there is a problem that it can not provide a more accurate and quick path depending on the fire.

In addition, the conventional route providing technology according to the fire receives information through a router including a plurality of sensors included in the building, and provides the escape route calculated by the reference server to each terminal through the network. Accordingly, since the prior art relies on the GPS for the position of the large pizza, there is a problem that a lot of errors are generated in generating an escape route, and the escape route is expressed by a request of the terminal possessed by the escapee, There has been a limitation in that it is necessary to expand the server and thereby cause cost inefficiency.

In addition, there is a limitation that the escape path can not be grasped in the case of a large pizza having a terminal.
