Generally, large buildings or buildings are equipped with emergency exits for evacuation in the event of an emergency such as a fire, and emergency evacuation lights and guidance lights are installed to inform the location of these emergency exits and guide the evacuation route.

In other words, the above-mentioned emergency evacuation lights are installed at each location, such as the entrance to the emergency exit, to indicate where people in the building can escape, and guidance lights are installed on the floor or wall at regular intervals to guide the path to the emergency exit. It is constructed to play a role.

Here, examples of prior art regarding emergency evacuation devices and methods for inducing quick and safe evacuation in the event of an emergency as described above include, for example, first, the "evacuation" as presented in Korean Patent Publication No. 10-1888467; There is a method of controlling an emergency lighting device that is easy to identify, a recording medium storing a program to implement it, and a computer program stored in the medium to implement it.

More specifically, the above-mentioned Korean Patent Publication No. 10-1888467 is a general lighting unit that illuminates the interior, a local lighting unit that illuminates a specific place, a control unit that turns on the general lighting unit and the local lighting unit when an emergency situation occurs, and a light source that lights up the general lighting unit and the local lighting unit when an emergency situation occurs. In the method of controlling an emergency lighting device that is easy to identify as an escape route for an emergency lighting device including a battery that receives and charges electricity and supplies power to the general lighting section, local lighting section, and control section in the event of a power outage, the emergency situation in which the control section receives an emergency situation signal input phase; A power check step in which the control unit checks whether external power is being supplied; And when an emergency situation signal is received in the emergency situation input stage and external power is confirmed to be supplied in the power confirmation stage, the control unit turns on the general lighting unit and local lighting unit, and the emergency situation signal is input in the emergency situation input stage and the power confirmation stage. If it is confirmed that external power is not supplied, the control unit controls one or more of the lighting maintenance time, brightness, color, and flashing cycle of the general lighting unit and local lighting unit differently from the status in which external power is supplied. Including, a method of controlling an emergency lighting device that is easy to identify an evacuation route and is configured to simultaneously secure visibility and provide escape guidance by dualizing the lighting into the part that illuminates the interior and the part that illuminates the emergency exit, and a program to implement this.

In addition, as described above, other examples of prior art regarding emergency evacuation devices and methods for inducing quick and safe evacuation in the event of an emergency include, for example, the "evacuation route" as presented in Korean Patent Publication No. 10-1887656. There is an “emergency lighting device that is easy to identify.”

More specifically, the above-mentioned Korean Patent Publication No. 10-1887656 includes a front lighting unit that illuminates the interior; Local lighting that illuminates a specific location; Disaster detectors that detect fire or earthquakes; An alarm unit that generates a warning sound; and a control unit that turns on the general lighting unit and local lighting unit when a fire or earthquake is detected by a disaster detector or a power outage occurs due to an emergency situation. The control unit activates the alarm unit when an emergency situation occurs, and the disaster detector includes a smoke detector and a heat detector. , a flame detector or an earthquake detector, and the local lighting unit relates to an emergency lighting device that is configured to illuminate the door handle, which is an easy place to escape, making it easy to identify escape routes.

As mentioned above, various technical details have been proposed regarding emergency evacuation for quick and easy evacuation in the event of an emergency such as a fire. However, the contents of the prior art as described above have the following problems.

In other words, in the event of a disaster such as a fire or earthquake, visibility is often difficult due to smoke or dust, so the emergency evacuation lights indicating the location of the emergency exit are often not visible or are overlooked in emergency situations. The contents of the prior art had the problem of not being able to fulfill its original function in cases where visibility was difficult due to smoke, dust, power outage, etc., as the evacuation route was indicated only with visual indicators such as lights.

In addition, in order to solve this problem, in addition to the conventional emergency evacuation lights that indicate emergency exits and evacuation routes, emergency alarms that generate alarm sounds in case of emergency are additionally installed. However, these emergency alarms also only incur additional costs. In addition, since most of them simply emit an alarm sound to indicate an emergency situation, it is difficult for people in the building to immediately determine the fact, location, and current situation of the accident, and even when they hear the alarm sound, they misunderstand it as a malfunction and respond accordingly. In some cases, failure to do so may lead to a fatal accident.

Therefore, as mentioned above, there are problems with the emergency evacuation of the prior art, which has limitations in that it cannot provide an emergency evacuation function when it is difficult to secure visibility in the event of a disaster because only a visual indication is provided, and an emergency situation occurs simply through an alarm sound. In order to solve the problem of the emergency alarm in the prior art, which had the limitation of not only notifying the situation but also making it difficult to determine what the situation was, it not only functions as a simple emergency evacuation light or emergency alarm, but also determines and notifies whether an accident has occurred, and also provides It is desirable to provide a new emergency evacuation notification and guidance system that can provide information on location, evacuation route, and method, but no device or method that satisfies all such requirements has yet been proposed.
