Description

Emergency Guidance System {EMERGENCY LEAD EXIT SYSTEM}

The present invention relates to an emergency guidance guidance system capable of preventing loss of life through rapid evacuation in case of an emergency situation.

In general, public address broadcasting refers to premises broadcasting such as apartment complexes, schools, government offices, large buildings, ports, and airports, and is used for emergency broadcasting in case of emergency situations such as fire as well as premises announcements.

For example, in the case of an emergency situation such as a fire, the public address system can minimize personal injury by notifying people through a speaker and inducing safe evacuation.

However, the existing public address system mainly provides voice-oriented broadcasting through a speaker, so there is a limitation in that it is not able to properly communicate intention to the hearing impaired. For example, even if the public address system broadcasts an emergency situation, there is a problem in that a hearing impaired person cannot recognize the emergency situation through a speaker and cannot receive an evacuation guidance to a safe place.

In addition, in the case of the visually impaired, even if an emergency situation is recognized through voice broadcasting, it is difficult to voluntarily evacuate because it is not possible to determine which direction to evacuate due to a visual impairment.

Therefore, the PLC module 210 only needs to receive an audio signal and a data signal through the two-wire cable line 300, and there is an advantage that it does not need to be supplied with separate power.

In addition, in the embodiment of the present invention shown in FIG. 4 described above, the display module 270 of each emergency door guidance device 200 has been described with a lamp unit 271 and a motor unit 272, but limited thereto. It does not work, and you can use a small projector.

That is, by configuring the display module 270 of each emergency door guidance device 200 as a miniature projector and projecting an evacuation guidance direction and a guidance message on a wall in case of an emergency, visual evacuation for the hearing impaired may be guided. In addition, it is obvious that each emergency door guidance device 200 can be installed on the wall and guide the evacuation by projecting an evacuation guidance direction and a guidance message on the ceiling.

This can be installed in facilities such as underground parking lots or underground shopping centers of theaters and buildings, and since the guide display can be made relatively large, it has the advantage of providing more intuitive guidance to people. In addition, it is possible to visually display a guide message synchronized with the same contents as the emergency announcement broadcast output from the voice output module 230 of each emergency door guidance device 200 as well as the evacuation guidance direction indication, so that the emergency situation is more detailed. It has an advantage that can be delivered.

Although a preferred embodiment of the emergency guidance system according to the present invention has been described above, the present invention is not limited thereto, and various modifications are made within the scope of the claims and the detailed description of the invention and the accompanying drawings.
