Description

[0001] Emergency exit system having outside air supply function [0002]

The present invention relates to an emergency escape system, and more particularly, to an emergency escape system capable of continuously supplying fresh air in the atmosphere along an emergency escape route while continuously guiding an emergency escape route from a building or underground facility in the event of a fire or the like. Emergency escape system.

The first cause of death in the field of fire is suffocation, not fire. Various chemical materials are burned and toxic gases such as carbon monoxide and hydrogen cyanide are discharged.

Accordingly, it is expected that fire victims will be able to greatly reduce fatalities if fresh air can be inhaled by large pizzas in the process of evacuation when a fire occurs. Various technologies are being proposed to meet such expectations.

Korean Utility Model Laid-Open Publication No. 20-2011-0002589 discloses a piping system in which piping lines composed of pipelines are separately provided so that external air can be supplied even in the event of a fire, and the suction of air is made strong as a compressor, In order to sufficiently supply the oxygen of the exhaust pipe.

However, such prior art technology is a risky technology that can generate a large-scale fatal accident if a large fire occurs because only oxygen is supplied to a specific sealed space such as a bathroom in the event of a fire.

In addition, since the victims of fatal accidents are attempting to escape to emergency exits, the majority of them are inhaling toxic gases. Therefore, portable masks equipped with a chemical air (CA) filter that effectively removes carbon monoxide when a fire occurs have been developed And is commercially available.

However, these portable masks and similar protective equipment can only be effective if they are carried directly by individuals at the site of the fire accident, so that it is possible to give the same help to everyone who is exposed to poisonous gas instantly in the event of a fire or other disaster. There are limits to the cycle.

The switch member 400 is preferably an on / off emergency button provided on the inner wall of the building so that users can easily operate the device when a fire occurs. However, the switch member 400 does not limit the switching method and the type of the switch .

In addition, the toxic gas detection sensor 500 is an electro-chemical sensor, which has an electrolyte for causing an oxidation and reduction reaction, and three electrodes. The configuration of the electrode includes a sensing electrode for sensing the concentration of the gas when it is adsorbed by the sensing gas, a counter electrode for performing a relative reduction reaction, a reference electrode for maintaining the potential of both electrodes constant REFERENCE ELECTRODE).

In the electrochemical sensor, a constant voltage is supplied from a TRANSMITTER in order to maintain a constant potential at a sensing electrode and a counter electrode with reference to a reference electrode. It is also possible to improve the sensitivity by changing the potential of the sensing electrode. When the gas to be detected touches the electrochemical sensor, the gas is adsorbed on the surface of the sensing electrode. The adsorbed gas starts oxidation and reduction reactions that are proportional to the concentration of the gas at a high rate. The oxidation and reduction reactions of the sensor cause a change in potential across the sensing electrode and the reference electrode.

This change in potential produces a current (uA) proportional to the gas concentration by Faraday's law. The generated output can be transmitted to the micom 600 through the TRANSMITTER, 4-20 mA, and the standard transmission output of the DC.

In the embodiment of the present invention, the microcomputer 600 is connected to a fire detection sensor 710-760 installed in an internal ceiling of a building or a smoke alarm 700 installed inside the building, When the fire detection unit 710-760 or the fire alarm 700 detects a fire occurrence, the predetermined one or more air blowing members 100 can be forcibly driven.

Hereinafter, the operation of the emergency escape system having the external air supply function according to the preferred embodiment of the present invention will be described with reference to the accompanying drawings.

First, as shown in FIG. 5, when a fire or the like occurs in a specific location within a specific building, a manager or a person around the manager presses one of a plurality of switch members 410-440 provided on the inner wall of the building.

Even when a specific person does not press the switch member 400, when the fire detection sensor 710-760 installed on the inner ceiling of the building is operated or the fire alarm 700 installed on the building sounds, the microcomputer 600 detects fire It can be judged that an emergency situation has occurred.

At this time, the microcomputer 600 senses an operation signal (for example, switch-on) of the switch member 400 and drives the plurality of blowing members 100 at a preset high rotational speed.

Accordingly, each of the blowing members 100 can continuously supply fresh air in the air to the inside of each air supply pipe 200.

At this time, the supplied air is discharged through a plurality of air discharge holes 210 formed at one side of the outer surface of each air supply pipe 200 at a predetermined interval and at a certain spraying angle and spray angle. FIG. 2 and FIG. 3 As shown in the drawing, the air injection area A injected from each air discharge hole 210 can form an irregular air tunnel continuously formed along the emergency escape route, so that the escapee can quickly When you move, you can safely inhale fresh air continuously supplied from the outside.

At this time, the microcomputer 600 controls the blower 100 so that the external air supplied through the air supply member 200 is continuously injected through the plurality of air exhaust holes 210 at a predetermined injection length and an injection angle, It is possible to control the operating speed and the degree of opening / closing of each of the on-off valves 250. For example, when the pressure sensor is provided at the end of the air supply member 200, when the pressure is lower than the threshold value, the operation speed of the blower 100 is controlled to be increased, The degree of opening and closing of the valve 250 may be controlled to adjust the predetermined injection length and the spray angle through the plurality of air discharge holes 210. [

At the same time, since the lighting member 300 continuously guides the predetermined emergency escape route, the escapee can quickly escape along the emergency escape route indicated by the lighting member 300, It is possible to continuously evacuate fresh air from the atmosphere, thereby enabling rapid evacuation in the event of a disaster such as a fire, and greatly reducing deaths due to suffocation or the like.

On the other hand, a toxic gas detection sensor 510 is provided in the vicinity of the arbitrary air blowing member 110, so that the toxic gas component contained in the air around the fire-generated building can be continuously detected.

1, the microcomputer 600 compares the detection value detected by the specific toxic gas detection sensor 510 with a predetermined reference value, and if the detected value does not exceed the reference value, the microcomputer 600 determines that the blowing member 110 If it exceeds the reference value, it is judged as an abnormal state, and the operation of the blowing member 110 is forcibly stopped.

At this time, when the toxic gas detection value detected by the toxic gas detection sensor 500 provided in the blowing member 110 exceeds the reference value, the microcomputer 600 stops the operation of the blowing member 110, The open / close valve 250 provided in the connection pipe 240 connected to the supply member 220 is opened to directly supply the air supplied from the blower 120 to the air supply member 210 connected to the blower 110 .

Accordingly, when a large amount of toxic gas is contained in the air, the air blowing member 110 is not operated and the toxic gas is not supplied to the interior of the building through the air supplying member 210 connected to the blower 110, Only fresh air can always be supplied continuously.
