Description

FIELD OF THE INVENTION The present invention relates to an emergency exit lamp and a control system thereof,

FIELD OF THE INVENTION The present invention relates to an evacuation guidance lamp for fire fighting and a control system thereof, and more particularly, to a fire evacuation guidance lamp and its control system which are capable of evacuation guidance by receiving a fire occurrence signal directly from a fire detector in an emergency such as a fire.

The currently used evacuation guidance systems are implemented according to the regulations stipulated in the Building Law and Fire Safety Management Standards. In addition, there is a tendency to improve and apply various contradictions by using advanced foreign systems such as NFPA (National Fire Protection Association) .

However, the evacuation guidance system has not made any progress, and only advances have been made regarding the extension of the lighting time or securing the illumination in case of emergency (in case of fire). In order to overcome the phenomenon that the evacuation passage is not properly recognized due to a large amount of smoke at the present time (in case of fire), some researches and uses an illumination system capable of indicating the evacuation route. However, It is close.

The point of the problem is, for example, a large-sized store where an unspecified large number of people go in and out, for example, a facility that can be watched frequently by an unspecified number of people who are not familiar with geography in a building. In addition, the evacuation guards for fire extinguishers have been recognized by many unspecified persons for a long period of time, and they are installed in places where an unspecified number of people can easily identify them due to the nature of fire evacuation guards.

Also, it is installed in a position where it is easy to find the evacuation route. The guide light is also turned on normally, and in case of an emergency, the emergency power supply is supplied and is lighted for a predetermined time.

However, in the case of large stores, it is pointed out that the passage is complicated and the unspecified number of people can not easily find the evacuation route. In addition, since these evacuation lamps (evacuation guiding lights, guiding lights, guiding lights, etc.) are installed in all passages and evacuation areas, if the evacuation guards are mistakenly evacuated, they will be able to miss evacuation times. In the worst case, .

An unspecified number of people who are in a state of panic are hard to make wise judgments, and in particular, there are situations in which the majority pursues blindly to a place where many are evacuated by the pursuing instinct. There is also a tendency for the regressive instinct to try to evacuate to the place where he or she always goes. This may lead to a more dangerous situation because the refugees blindly escape without knowing the precise location of the fire and the dangerous situation.

FIG. 1 is a plan view schematically showing an evacuation state in which a refugee in a building is generally panicked and a refuge is performed using only a left refuge staircase by a pursuing instinct and a return instinct.

As shown in FIG. 1, a fire occurred in the area C in the first zone, and an example in which a large number of people are driven toward the left step by the following instinct and regression instinct can be seen.

This delayed the evacuation time and caused a lot of dangerous situations due to crowded crowd. In the case of a high-rise building, even in the case of a pathway guide light installed at a stairway, there is no evacuation guidance system (ie, no evacuation guidance indicator function) It is.

In other words, in the case of a 5th layer fire, some floors below 5 F (floor) as well as above 5 F (floor) will be filled with smoke. At this time, when people are trying to evacuate from a layer other than 5 F (layer), it is difficult to accurately determine from which layer a fire occurs and in which direction it is effective to evacuate.

For example, evacuees of 4F (floors) and 3F (floors) may evacuate to 5F (floors) where fire occurs. Also, people of 6F (floor) and 7F 5F (layer) will be evacuated. It is preferable that evacuees with more than 6F (layer) evacuate upstairs, and those with less than 5F (layer) evacuate as far as possible.

However, the present evacuation guidance lamps (passageway guide lamps, escape guidance lamps, guiding lights, etc.) do not have an evacuation guiding function, and other guiding devices are close to the function of an emergency lighting lamp rather than a concept of securing a safe evacuation route. Also, these devices are not easily understood and recognized by many unspecified masses (they are not popularized and universalized), and they are difficult to respond appropriately to the changing situation of the fire scene.

Also, because there are many different parts different from the existing fire fighting system, many people have a lot of contradictions to evacuate instantaneously. Therefore, the conventional fire fighting system, that is, the fire extinguisher and fire evacuation guidance function (fire evacuation passageway and evacuation hole display function) in normal and emergency, is additionally provided with an evacuation guidance direction display function capable of transmitting fire information and securing an evacuation route There is no control system for a fire-fighting evacuation guide light.
