Description

FIRE EXIT GUIDES DEVELOPED IN FIRE

[0001] The present invention relates to a fire extinguishing system for fire extinguishing, and more particularly, to a fire extinguishing system for fire extinguishing, The present invention relates to an emergency exit guide device for fire extinguishing that is provided to assist escape of non-disabled persons and visually impaired persons by having the function of braille in addition to liquefaction.

A fire is a combustion phenomenon caused by intentional or unintentional burning of a person. It is necessary to extinguish the fire using a fire extinguishing facility. (National Fire Safety Inspection and Reporting Regulations Article 2 (1)). When a fire occurs, heat, smoke and flames ascend in a hot state and move through various gaps leading to the upper layer. This case is referred to as a combustion enlargement phenomenon, and the indoor temperature rises sharply. When evacuating, you should be able to get less heat and smoke and safely evacuate.

It can not last for about 1 hour at 66 ℃, about 15 minutes at 121 ℃, about 5 minutes at 149 ℃, 30 seconds at 177 ℃ The skin may change to a state in which it can not be restored to dryness. Therefore, it may be killed by combustion products (smoke, toxic gas, etc.) generated by heat or mass unless the fire is evacuated immediately.

Zion paint can be applied as a guide device to safely escape from the risk of fire.

Typically, Zion paint is a special paint made by changing color when the temperature reaches a certain level. It is a compound that discolors when a certain temperature is included by including pigment in the coating. It is used for chameleon paint, thermo-paint, Also known as temperature.

The specific temperature at which the color is discolored is determined by the mixing ratio of the pigment to be mixed with the composition, so that the user can change the color in a desired temperature band. The reversible zeolite can be used any number of times because it returns to its original color when it is cooled even when it is discolored due to a rise in temperature, and the irreversible zeolmachine does not return to the original color once it is discolored.

In this regard, Korean Patent Laid-Open Publication No. 2015-0056423 discloses fire detection using zion paint. In Patent Publication No. 2015-0056423, warning signs or warning signs are painted on a door in a building using a sion pigment, and a general pigment of the same color as the sion pigment is painted on the portion except for the portion painted with the sion pigment, The warning phrase or the warning sign painted with the zeon pigment is not displayed, but the warning phrase or the warning mark painted with the zeolite pigment is visually distinguished as the zeolite pigment is discolored as the temperature rises during the fire.

Patent Publication No. 2015-0056423 discloses a method for accurately detecting the progress of a fire through the color change of the zeolite pigment and thereby reliably and promptly transmitting the information about the fire area to the evacuees when evacuating personnel, .

However, Patent Publication No. 2015-0056423 fails to take the evacuation of the visually handicapped person into direct guidance to an emergency exit.

Most blind people are very familiar with the surrounding and frequent passageways, but the evacuation route is mostly different from the usual one, so the help of the evacuation assistant is needed to be safe through the evacuation route. However, since they can not be with a person who can always help (non-disabled), a way to evacuate the blind person alone should be devised.

The Braille block is used to reduce the trial and error that a blind person experiences during the walking process due to the fact that the three elements of straight walking, redirection, and destination detection are not performed consecutively, and guide the more accurate walking position and direction. Also, only those who can not distinguish between contrast and darkness are not visually impaired, and those with low vision (those who can distinguish a certain object) have a considerable number (about 90%).

On the other hand, Korean Patent Registration No. 1006996 discloses a braille block for subway reporting. Korean Patent Publication No. 1006996 discloses that a cover plate having a predetermined height and area and having a mounting space protruding at a predetermined interval is formed in a transparent manner using polycarbonate, A braille block is formed by mounting a circuit board on which a plurality of light emitting diodes are mounted at positions corresponding to the mounting spaces; The circuit board (24) is mounted separately in the mounting space and is equipped with at least one vibration motor; The braille block is connected to a control device which recognizes the operation of the fire alarm according to the occurrence of a fire and transmits an operation signal to the circuit board and the vibration motor; In the event of a fire or an emergency, the vibration motor is operated in response to a signal transmitted from the control device to cause vibration in the braille block, and the light emitting diode mounted on the circuit board is moved in the direction of the arrow So that the blind or passengers can move to a safe place.

[0005] Japanese Patent Application No. 1006996 discloses a method for controlling a visually impaired person through a transparent braille block provided with a fire alarm, a control device, and a light emitting diode. In the emergency, when a fire occurs, There is an advantage that it can be evacuated to a safe place.

However, Japanese Patent Publication No. 1006996 has a problem that installation and maintenance costs are high because a power source must be provided for the flashing of a light emitting diode. In addition, since a fire alarm due to a fire occurring due to power failure can not be operated, it is impossible to guide the fire alarm to a safe place. Therefore, a device capable of promptly and safely guiding the fire alarm at an imminent instant is needed.
