Intelligent evacuation laser guidance system {GUAID APPARATUS OF EMERGENCY EXIT}

The present invention relates to an emergency exit guide device, and more particularly, to guide the emergency exit even in the smoke during a fire or an emergency, and to escape to the outside during an emergency disaster such as an emergency exit guide device and a fire that can notify the occurrence of a fire To provide an intelligent evacuation guidance system based on wireless communication to automatically guide the direction of the emergency exit. In particular, in case of disaster, it is prepared for the breakdown of power and wired communication, and it uses a communication network based on wireless communication to build a network in a building, and the indicators of heavy smoke generated in a fire The system is implemented by using EL wire that can emit linear light for identification.

In general, emergency exit guide devices are installed in the upper or corridors of emergency exits to inform the location of emergency exits in buildings, subways and underground spaces so that people in buildings or subways can evacuate quickly by evaluating the location of emergency exits in case of fire or other emergencies. Make sure

Such a guide device includes a case installed at an upper side or a corridor of an emergency exit, a fluorescent lamp provided in the case to emit light, and a floodlight panel on which the display portion such as letters and arrows of the emergency exit emits light due to the emission of the fluorescent lamp on the front of the case. .

However, such a general emergency exit guide device has a problem that it is difficult for people in the building to identify the emergency exit guide device in the event of a fire or other emergency situation as the intensity of the fluorescent lamp rapidly penetrates through the floodlight panel.

In view of this, the emergency exit guide light of Republic of Korea Utility Model Registration Publication No. 0329023 is disclosed. The disclosed emergency exit guide light has a structure which improves visibility by illuminating a thickness surface of a display panel of transparent or translucent material, which is displayed by engraving or printing a guide cover for guiding the emergency exit on at least one surface.

However, there was a problem in that visibility is still poor due to the smoke generated during the fire.

On the other hand, there is disclosed a guide speaker built-in emergency exit induction lamp of Republic of Korea Patent Publication No. 0734475. The disclosed speaker built-in emergency exit induction light is installed on the floor of the emergency exit induction light, and the voice output unit for guiding the location of the emergency exit with a voice so that people in the building can recognize the location of the emergency exit by hearing rather than sight. However, since the emergency exit induction light is installed on the floor of the building, there was an inconvenience of maintaining cleanliness at all times for visibility, and it was difficult to recognize the location of the emergency exit by guiding the location of the emergency exit to the first-time visitors to the building. there was.
