Description

[0001] The present invention relates to an exit lamp and a control system thereof,

The present invention relates to an evacuation guidance lamp and a control system thereof. More particularly, the present invention relates to an evacuation guidance lamp and a control system thereof installed on a bottom surface of a building for emitting a fire generation signal from a fire detector or fire receiver in an emergency, Control system.

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 that, in the case of a large store where an unspecified number of people go in and out, for example, a facility that can be watched by an unspecified number of unspecified people who are unfamiliar with geography in the building is a fire fighting guide lamp. In addition, fire-fighting guide lights have been recognized by many unspecified persons for a long period of time, and are installed in places where an unspecified number of people can easily identify them due to the nature of the fire-fighting guide light.

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 fire escape lamps (escape guiding lights, guiding lights, guiding lights, etc.) are installed in the passageways and evacuation areas, it is possible that the evacuator misses the evacuation time in the worst case, and 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.

However, current fire guidance lamps (guiding lights for guiding passages, escape guiding lights, audience guides, etc.) do not have an evacuation guiding function and other guiding devices are close to the function of an emergency lighting device 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. Accordingly, in the past, a fire extinguisher (fire extinguisher) and a fire extinguisher display function (fire extinguishing passageway and evacuation exit display function) in which the function of a fire extinguisher is maintained in normal and emergency situations. There was no control system.

In addition, when a fire occurs, due to the smoke, people will fall down and evacuate. At this time, difficulty in evacuation due to difficulty in securing visibility of a guide light attached to a ceiling or a wall.

Therefore, in recent years, even if the intensity of light does not weaken and the laser beam passes straight through long distance and passes through smoke, the evacuation guidance lamp that irradiates the laser beam easily recognizable even if the smoke inside the building does not lose its straight- Has been proposed.

As a means of lighting such as an evacuation guide, fluorescent lamps and recently LEDs are mainly used. When the distance between the fluorescent lamps and the LEDs is reduced, the intensity is weakened and scattered to smoke or dust. When the smoke starts to smoke inside the building, The visibility distance that can be made is shortened sharply so that the function can not be performed.

Therefore, in recent years, even if the intensity of light does not weaken and the laser beam passes straight through long distance and passes through smoke, the evacuation guidance lamp that irradiates the laser beam easily recognizable even if the smoke inside the building does not lose its straight- Has been proposed.

Patent No. 0699361 entitled " Emergency Passage Indicator with Character and Symbol Projection Method Using Laser Diode and Optical Lens ", Registered Utility Model No. 0320784 "Moving Evacuation Induction Display generating laser guide lamp ".

Although the laser beam is strong in straightness and excellent in permeability even in dark smoke, it can be recognized even at a long distance, but it is impossible to grasp in which direction the evacuation person should evacuate just by recognizing the laser beam irradiated. That is, the laser beam irradiated in the same area without any change can only recognize that the evacuator is irradiated with the laser beam, and can not know in which direction the laser beam should evacuate.

In addition, if the laser beam is directly irradiated to the eye of the large pizza, there is a risk that the evacuator will lose sight.

An object of the present invention is to provide an emergency evacuation lamp and a control system thereof which are installed on the bottom surface of a building and emit a fire signal from an emergency fire detector or fire receiver in the event of a fire, The purpose is to provide.

In the embodiment of the present invention, the main body case 111 is formed in a circular shape, a groove is formed in the bottom surface at a predetermined depth, and the main body case 111 is embedded in the groove to prevent people from being caught in the movement. That is, the uppermost surface of the main body case 111 installed on the bottom surface of the building is configured to be flush with the bottom surface. Meanwhile, the main body case 111 can be formed in various shapes such as a square shape and a triangle shape as well as a circular shape.

The optical fiber 112 is configured to surround the inner space of the body case 111. A red LED 117 is coupled to one side of the optical fiber 112 and a green LED 118 is coupled to the other side.

That is, a red LED 117 is inserted into one side of the optical fiber 112 and a green LED 118 is inserted into the other side. When the red LED 117 emits light, the entire optical fiber 112 is irradiated with red light And when the green LED 118 emits light, the entire optical fiber 112 emits green light.

The optical fiber 112 is disposed so as to surround the inner space of the main body case 111. When the optical fiber 112 has a certain angle at an edge portion thereof due to the characteristics of the optical fiber 112, The portion is arranged to have a certain curvature in a round shape.

Meanwhile, in order to minimize the effective dispersion of the light, that is, the bent portions of the optical fiber 112, the red LED 117 and the green LED 118 ) May be inserted.

The battery 113 is a rechargeable type and is connected to the first LED module 115 through the battery 113 when no power is supplied to the first LED module 115 from an external power source module through the MCU 120. [ So that the white LED 119 is turned on.

The RF communication module 114 serves as a communication device to transmit a signal through an RF communication with an adjacent guide light and to receive a fire occurrence signal from a fire detector or a fire receiver. Here, although the RF communication module 114 is described as an embodiment in the embodiment of the present invention, the present invention is not limited to the specific communication method, but may be applied to the data communication between the adjacent directors via Wi-Fi communication, bluetooth and beacon communication, You can also send and receive. The RF communication module 114 performs communication within a range of 447 MHz to 2.4 GHz in the RF communication band.

Here, the RF communication module 114 communicates with neighboring RF communication modules and transmits information to each other when a fire signal is received from the fire detector or the fire receiver.

The MCU 120 receives the fire signal from the fire detector or the fire receiver through the RF communication module 114 to control the second LED module 116 and the second LED module 116 And selectively drives the red LED 117 or the green LED 118 under the control of the MCU 120.

The MCU 120 can adjust the driving time of the second LED module 116. For example, the MCU 120 selectively emits the red LED 117 or the green LED 118, So as to have a predetermined period so that people can easily confirm the light emission.

Here, the MCU 120 and the second LED module 116 are described as being separate from each other. However, the present invention is not limited thereto.

The white LED 119 is connected to an external power supply unit and is always in a lighted state. If it is determined that the power is not supplied through the MCU 120, It is driven by supplying necessary power.

When the evacuation guidance lamp 100 according to the present invention configured as described above receives a fire occurrence signal from the fire detector or fire receiver at the RF communication module 114 while the white LED 119 is normally emitting light, And the MCU 116 selectively emits a red LED 117 or a green LED 118 connected to the second LED module 116 to guide the inside of the building to quickly evacuate I will do.

At this time, the RF communication module 114 communicates with neighboring guide lights to emit a red LED 117 in a region where a fire has occurred and an area adjacent thereto, and a green LED 118 emits a green region in a non- Guide the evacuees to evacuate quickly to the area where the fire does not occur.

Meanwhile, the green LED 118 is sequentially and repeatedly driven along the evacuation direction under the control of the MCU 120, so that people evacuating to a low posture in order to reduce respiratory damage caused by smoke are guided by a guide light According to the color, evacuation direction can be quickly recognized and evacuated.

In addition, when a fire occurrence signal is received through the fire detector or the fire receiver, RF communication is performed between neighboring guide lights 100 to turn on or flash the red LED 117 to notify that a fire has occurred, Can occur.

Further, the arrow direction of the guide light 100 is indicated, and the arrow direction is displayed by the light emission of the red LED or the green LED.

Therefore, in order to solve the problem that the evacuation guide lamp according to the present invention can not safely evacuate due to smoke, it is possible to guide the evacuation lamp in the evacuation direction by emitting red or green light on the floor surface.

2 is a block diagram schematically showing a control system for an evacuation guidance or the like according to the present invention.

As shown in FIG. 2, the control system for an evacuation guidance and the like according to the present invention includes a plurality of guide lights 100 attached to a floor to induce warning signs and evacuation, A fire detector 200 for detecting at least any one of a fire signal generated by the fire detector 200 and transmitting the fire signal to the guide light 100, (400) for amplifying and transmitting the fire signal to the fire receiver (300) for receiving and processing the fire signal, an analog control signal output from the fire receiver (300) D converter 500 for outputting a fire generation signal to the guide lamp 100 in response to a digital control signal from the A / D converter 500 A wireless repeater 700 that receives a fire occurrence signal from the gateway module 600 and transmits the received fire signal to the guide light 100 and a wireless repeater 700 that receives the fire signal from the gateway module 600 through RF communication from the wireless repeater 700 or the guide light 100 And a terminal 800 for receiving the data and confirming the current status and alarm information of the wireless repeater 700 or the guide light 100.
