Description

Fire emergency induction system with LED emergency exit indicator using low power wireless sensors {firesafe induce system including emergency exit guide lamp using low power wireless sensors}

The present invention collects the detection results from the detection sensor and fire emergency display consisting of an LED emergency exit indicator consisting of an LED module capable of guiding various emergency situations and a fire receiver to extract the evacuation path by collecting all the detection results To an induction system.

In particular, the present invention relates to a fire emergency indication guidance system that collects the detection results from the detection sensor and the LED emergency exit indicator located in the near area by using a low power wireless detection sensor and transmits them to the fire receiving panel.

In addition, the present invention based on the map information of the entire building and the location information of the detection sensor, to determine the location of the fire caused by the detection result to extract the entire evacuation route, the fire led by the LED emergency exit indicator to evacuate to the evacuation route It relates to an emergency indication guidance system.

In general, a building such as a restaurant, a theater, or an office is essentially provided with a light to guide people to an emergency exit in case of an emergency such as a fire or a power failure. Most of these emergency exit lights are turned on for a certain time even if the power is cut off due to fire or power failure, so that people inside the building can easily find the emergency exit.

Conventional emergency exit indicators are mostly a case (Case) with a front opening in the form of a rectangular box (Box), a fluorescent lamp installed inside the case, a fluorescent device to selectively turn on (on) / off (fluorescent), Covers the front of the case and is engraved with phrases such as 'Emergency Sphere', the fluorescent cover (Cover) to express the engraved phrase to the outside according to the emission of the fluorescent lamp installed inside the case, and the main power of the building It is composed of a spare battery (battery) for temporarily supplying power to the fluorescent device when the power is not supplied from.

Therefore, when a fire or power outage occurs in a building or the like and enters an emergency situation, a conventional emergency exit indicator light may be engraved on a fluorescent cover using a spare battery provided in its case 110 even if the main power supplied from the building is not supplied. Fluorescent lamps will be emitted to the outside, and people inside the building will be able to see the emergency exit lights that are being displayed outside and evacuate quickly and safely to the outside along the emergency exit guided by the emergency exit lights.

The conventional emergency exit indicator is using a commercial power source and a backup rechargeable battery as a power source, and indicates that the emergency exit by a fluorescent lamp or LED or one lit arrow. However, there is a disadvantage in that it is difficult to effectively present the evacuation direction to the evacuees simply by indicating that it is an emergency exit by a light emitter or displaying a lit arrow in an urgent situation due to a fire.

In order to overcome this, an example of a technique related to an emergency exit induction lamp which instructs the evacuation direction of the evacuator in a fire is directed to the emergency exit [Korea Patent No. 10-0715843 (published May 8, 2007), "Emergency exit induction lamp using LED"] (Hereinafter referred to as prior art 1). The prior art 1 discloses an emergency exit induction lamp using an LED that allows the evacuator to intuitively recognize the escape direction even in the smoke by dynamically indicating the exit direction while sequentially flashing the high brightness LED (LED) when a fire occurs.

In addition, the conventional emergency lights only endure the location of the emergency exit, so people who enter for the first time in an unfamiliar building do not know at all which part of the emergency exit the current location is when they encounter such an emergency situation. There is a problem in that it is impossible to detect whether the evacuation in the direction or the time it takes to evacuate to the outside through the emergency exit at all.

In view of such a problem, an example of a technology related to an emergency light device having an audiovisual recognition means to allow people to easily find an emergency exit is disclosed in Korean Patent Publication No. 10-2004-0091496 (October 28, 2004). Emergency light device having a "] (hereinafter referred to as Prior Art 2). The prior art 2 is a case that serves as a main body, an LED display unit installed inside the case and indicating a phrase such as 'emergency sphere', and a character that enables to modify or change the phrase such as 'emergency sphere' from the outside. A configuration including an input unit and a user memory unit for storing such correction or change data when externally modifying or changing a phrase such as 'emergency phrase' has been disclosed.

However, the prior arts may cause a greater disaster when the evacuation route is changed depending on the location of the emergency situation such as a fire. An example will be given with reference to FIG. 7.

As shown in FIG. 7, suppose that the emergency exit has A stairway to the west and B stairway to the east, and assume that a fire has occurred near the B stairway. In general, the emergency exit indicator will point towards the nearest emergency exit. Therefore, an emergency exit indicator (3, 4, 5, 6) located closer to the east exit B than the west exit A will guide the evacuation toward the east exit B. However, the evacuation evacuated to emergency exit B is to evacuate near the fire, and therefore there is a risk of further disaster.

On the other hand, a fire receiving panel is installed that detects an emergency situation such as a fire or a power failure and immediately transmits the emergency situation to a relevant department or institution such as a fire station or a disaster prevention room. In addition, the sensors are installed at regular intervals in the building to detect a fire or power outage and connected to the fire receiving panel. Normally, the sensor is wired to receive power and send the detection results to the fire station.

However, in case of emergency such as fire, in many cases power failure is accompanied. In this case, the detection sensor is supplied with power from the emergency power source, or the power is cut off, so that the detection result cannot be transmitted to the fire receiver. In the former case, there has been a problem that the installation is complicated and expensive to connect the wires to the sensing sensors installed throughout the building.

In order to overcome such a problem, an example of a technology for a wireless fire detector and a receiving panel using a wireless fire wiring system is disclosed in [Korean Patent Laid-Open Publication No. 10-2004-0040748 (published on April 13,200), "Wireless Fire Detector and Receiver"]. (Hereinafter referred to as prior art 3). The prior art 3 discloses a configuration including a sensor connected to a sensor for detecting temperature, humidity, smoke, infrared rays, odors, gas, and the like, and a fire receiving panel wirelessly connected to the detector.

However, the above prior art 3 has in mind that the sensor is connected to the wire of the sensor and the wire. Therefore, if the power of the sensor is used separately, there is a risk that it will not operate in case of power failure, if the power is supplied from the detector, the battery of the detector may be faster, and if the wiring between the sensor and the sensor is disconnected, the sensor receives the detection result from the sensor. There is a risk of not being able to.

In addition, since most of the induction light is not provided with a separate means of directing the emergency exit in a single configuration there was a problem that can not faithfully serve as an induction light to direct the direction of the emergency exit in case of emergency.

In addition, the current location of the induction lamp is located in a high place, so it is difficult to find the direction of the emergency exit because it is invisible due to the smoke generated in the event of a fire. Because of the low directivity (the property that indicates how much light goes straight in a certain direction), the light does not reach far through the thick smoke of the fire site, and the light spreads to the stray light only near the emergency exit. There was also a problem that could not direct people to the exact location of the emergency exit.

An object of the present invention is to solve the problems as described above, to collect the detection results from the sensor and collect all the LED emergency exit indicators and detection results consisting of LED modules that can guide various emergency situations to determine the location of the fire It is to provide a fire emergency indication guidance system consisting of a fire receiver to extract the evacuation route.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

First, a configuration of a fire emergency indication guidance system according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

1 is a block diagram of the configuration of the fire emergency display induction system according to an embodiment of the present invention, Figure 2 is a block diagram of the detailed configuration of the LED display of the LED emergency exit indicator in accordance with an embodiment of the present invention.

As shown in Figure 1, the emergency display induction system according to the present invention is composed of a sensor 10, LED emergency exit indicator 20, fire receiving panel 40.

The detection sensor 10 is a sensor that detects temperature, humidity, smoke, infrared light, smell, gas, and the like. In particular, the sensor 10 is a sensor for wireless communication. Preferably, Zigbee, RF communication, short-range wireless communication such as Bluetooth is used. More preferably, Zigbee communication is used.

In particular, Zigbee (Zigbee) is a representative technology of short-range wireless network with low power, low cost, and ease of use. It is a technology that standardizes higher protocol and application based on phy layer and MAC layer of IEEE802.15.4 standard and is applied to home automation suitable for remote control and management application. As one of the international standards of WPAN, wireless communication and simple structure make it small size, easy to design, low development cost and low power, but communication is very stable. In particular, the power consumption is low enough to operate several years with two AA batteries.

Zigbee is a technology that will play a pivotal role in the construction of a ubiquitous sensor network environment, and thus has the advantage that the Zigbee sensor used in the sensor network environment can be used as it is.

On the other hand, when the sensor 10 is used wirelessly, it must supply its own power. Therefore, the sensor 10 is configured to include a battery. When the battery is used, since the battery needs to be replaced, the sensor 10 has a lower power.

In summary, the sensor 10 is composed of a sensor module, a wireless communication module, a battery.

On the other hand, as shown in Figure 1, the detection sensor 10 belongs to the emergency exit indicator 20 in the vicinity, and transmits the detection result to the emergency exit indicator 20 to belong. When the detection sensor 10 transmits the detection result in a broadcasting manner, a plurality of emergency exit indicators 20 in the vicinity may receive the detection result. In this case, as described below, the detection result value is distinguished by an identifier of the detection sensor 10.

In another embodiment, the sensor 10 is connected to the emergency exit indicator 20 by wire. Wired connection with the sensor 10 uses a technique for connecting a conventional sensor.

LED emergency exit indicator 20 is composed of a case, LED display unit 30, a control circuit, a power supply. Since the case and the power supply unit use the conventional technology, detailed description thereof will be omitted.

As shown in Figure 2a, the LED display 30 is mounted on the front of the LED emergency exit indicator 20 as a whole. The LED display unit 30 is configured by connecting a plurality of LED modules 31 horizontally. In general, the LED module 31 is produced is composed of a square array, such as 8 X 8, 16 X 16. That is, the LED module 31 is composed of eight or sixteen pixels 32 each on the X-axis and the Y-axis, and each pixel 32 is equipped with at least one LED 33. LED module 31 is divided into a single color or color. In the case of a single color, one LED 33 is provided in the pixel 32, and in the case of a color, the LEDs 35 having at least two different colors are provided in the pixel 34.

The configuration using the LED module 31 is to use the product of the LED module 31 produced in large quantities. In particular, since the commercialized LED module 31 is equipped with a drive circuit for displaying various types of letters in various ways, the development of the LED display unit 30 is easy.

In FIG. 2A, the LED display unit 30 is configured by horizontally connecting four 8 X 8 LED modules. It is preferable to connect at least four LED modules in order to display basic words indicating emergency situations such as "emergency exit" and "fire occurrence" at once.

In addition, as shown in Figure 2b, each LED module 31 of the LED display unit 30 is provided with a drive driver 36 for controlling the display in a variety of letters and various forms. The connector 37 connects the driving driver 36 and the LED control unit 21.

In another preferred embodiment, the LED 33 and 35 are installed directly on a required pixel, for example, 8 X 24 pixels, without using a plurality of LED modules 31, and driving to control the entire pixel. A driver 36 is provided.

The latter embodiment uses a LED module having 8 X 24 pixels, 16 X 48 pixels, or the like, or manufactures such an LED module directly. In particular, when mass-producing the LED display unit 30 of the present invention, it will be possible to manufacture the LED module directly.

Next, the configuration of the LED emergency exit indicator 20 according to an embodiment of the present invention will be described in more detail with reference to FIGS.

3 is a block diagram of the configuration of the LED emergency exit indicator according to an embodiment of the present invention, Figure 4 is a view showing an example of the guide display of the LED emergency exit indicator according to the invention.

As shown in FIG. 3, the LED emergency exit indicator 20 includes an LED indicator 30, an LED controller 21, a sensor receiver 22, a detection result transmitter 23, an emergency signal receiver 24, and an indicator memo. Lee 25 is composed. In addition, the circuit breaker signal circuit 26 may be further included.

As described above, the LED display unit 30 is composed of a plurality of LEDs in the form of a grid.

The sensor receiver 22 wirelessly receives the detection result from the sensor 10. As seen above, the sensor 10 is a wireless sensor for sensing the temperature, power failure, and the like. Preferably, the sensor 10 is a Zigbee (zigbee) wireless sensor, the sensor receiver 22 receives data from the sensor 10 in a Zigbee (zigbee) communication method.

The data received by the sensor receiver 22 from the sensor 10 is an identifier of the sensor 10 and a detection result value. The identifier of the detection sensor 10 is for identifying the detection sensor 10, and is a serial number, ID, etc. assigned to each detection sensor 10. The detection result is either numerical value or status value of On / Off. For example, in the case of a temperature sensor, it is a sensed temperature, and in the case of a gas leak sensor, it is sensed as on if it leaks, or as off if it does not leak.

The sensor receiver 22 stores the received detection result in the indicator memory 25. The sensor receiver 22 receives the sensing result from the sensing sensor 10 in almost real time and stores it in the memory as soon as it is received. In addition, the plurality of sensing sensors 10 all receive and store.

The detection result transmitter 23 transmits the detection result to the fire receiving panel 40.

Since the detection result is stored in the indicator memory 25 by the sensor receiver 22, the detection result transmitter 23 reads the stored detection result and transmits it to the fire receiver 40. The detection result transmitter 23 transmits at a predetermined time interval. Therefore, all the detection results stored during the time interval are transmitted.

On the other hand, preferably, the detection result transmission unit 23 transmits data wirelessly with the fire receiving panel (40). The emergency exit indicator 20 and the fire receiver 40 may be at a considerable distance. Therefore, the wireless communication between the fire receiving panel 40 and the emergency exit indicator 20 is not preferable to use a short-range communication method. If you use short-range communication method, it is desirable to connect with an amplifier in the middle.

In another embodiment, the detection result transmitter 23 transmits data to the fire receiving panel 40 by wire. Wired connection uses a technique for connecting the wire with the conventional fire receiving panel 40.

The emergency signal receiver 24 receives emergency indication data including a display direction, a display phrase, and a display method from the fire receiving panel 40. In particular, the display phrase is any one of the left or right arrow shape, the guide phrase, the display method is any one of the lighting method, flashing method, flow method, the display direction is any one of the left or right, neutral.

The display phrase refers to a left or right arrow shape such as "=>", "<=", or guidance phrases such as "emergency", "fire occurrence", or "power outage". In particular, by collecting the detection result of the sensor 10 in the fire receiving panel 40 to determine the exact location of the fire, it can transmit a specific guide phrase, such as "three-layer fire". In addition, the shape of a guide sign or the like used for fire safety such as a fire or a power failure may be included in addition to the arrow.

Display methods include lighting, flashing, and flow. The lighting method is to turn on the display phrase by turning on the LED display unit 30, the flashing method is to repeat the off and on. The flow method refers to a method of displaying as the display phrase flows from the left to the right or the right to the left in the LED display unit 30.

For example, FIG. 4A is an example in which the guidance phrase "emergency phrase" and the right arrow ">" are displayed on the LED display unit 30 together. 4B to 4E show an example in which the right arrow of "> " is displayed in a " flow method " from left to right. The right arrow may be various types of arrows other than ">".

The display direction is any one of left, right, and neutral, and means a direction to be evacuated. Since the emergency exit indicator 20 is made long to the left and right, the emergency exit indicator 20 can guide the evacuation route to the left or right direction depending on the installed state. For example, if the evacuated exit is to the right of the emergency exit indicator 20, the display direction is "right".

The arrow shape of the display phrase indicates the display direction, and the "flow" of the display system is also controlled to flow in the display direction. On the other hand, if it cannot be determined in the right or left direction, it is determined as the display direction of "neutral".

On the other hand, as another preferred embodiment, the indicator memory 25 stores a display phrase and a program for performing each display scheme, wherein the display phrase and the display scheme are distinguished by an identifier, and the emergency signal receiver 24 Receives emergency indication data including an indication phrase and an identifier of a manner of indication.

That is, display phrases such as "fire occurrence", "emergency phrase" and "power outage" are stored in the memory 25 in advance, and each display phrase is given an identifier, for example, a serial number. And when receiving "2" from the fire receiving panel 40 outputs the stored "emergency phrase" display phrase to the LED display unit 30. In this case, the amount of data received from the fire receiving panel 40 can be reduced.

In addition, the LED output according to the display method is implemented by a display program. Therefore, if the identifier of the display program according to the display method is determined, the LED is output in the desired display method using only the identifier of the program. Since the display program uses a conventional LED output program, a detailed description thereof will be omitted.

The indicator memory 25 stores the detection result or emergency indication data.

The LED controller 21 controls the LED display unit according to the emergency display data. As described above, the LED control unit 21 transmits a control signal to the drive driver 36 of the LED module 31 through the connector 37, and outputs the display phrase as an LED in a desired form.

The line disconnection signal circuit 26 generates a line disconnection signal and inputs it to the LED controller 21 when the communication line connected to the emergency signal receiver 24 and the fire receiver 40 is disconnected.

As described above, the display of the LED display unit 30 of the emergency exit indicator 20 is entirely controlled by the emergency display data of the fire receiving panel 40. By the way, if the situation occurs, such as a failure of the fire receiving panel 40, the emergency exit indicator 20 may not operate at all. Therefore, in case of this, the communication line connected to the fire receiving panel 40 detects the disconnection, and if a disconnection is detected, an emergency indication is generated by itself.

Emergency indications occur according to the saved emergency indication data by default. To this end, the indicator light memory 25 stores emergency indication data to be generated in a basic situation.

On the other hand, preferably, the above-described detection result transmitter 23, sensor receiver 22, emergency signal receiver 24, LED controller 21 by the program stored in the microprocessor and indicator memory 25, respectively Implement

Next, the configuration of the fire receiving panel 40 for controlling the LED emergency exit indicator according to an embodiment of the present invention will be described in more detail with reference to FIG. Figure 5 is a block diagram of the configuration of a fire receiving panel for controlling the LED emergency exit indicator light according to an embodiment of the present invention.

As shown in FIG. 5, the fire receiving panel 40 includes an emergency light receiving unit 41, an emergency light control unit 42, an emergency light extracting unit 43, and a receiving panel memory 44. In addition, the emergency alarm transmitter 45 may be configured.

The receiving panel memory 44 stores map information of a building including a building passage and an emergency exit, location information of the sensor 10 installed in the building, and location information of the LED emergency exit indicator 20 installed in the building.

That is, the reception board memory 44 stores all the passage information of the entire building and information on where the sensor 10 and the LED emergency exit indicator light 20 are located in the building. These information are previously input by the administrator and stored.

The emergency light receiver 41 receives the detection result of the detection sensor 10 from the LED emergency exit indicator 20 and stores it in the reception panel memory 44. The emergency light receiver 41 wirelessly receives data from the detection result transmitter 23 of the LED emergency exit indicator 20. As previously seen, the received data is an identifier of the sensor 10 and a detection result value. The identifier of the detection sensor 10 is a serial number, ID, etc. for identifying the detection sensor 10, and the detection result values are numerical values or state values of On / Off.

When the emergency light extraction unit 43 receives an emergency detection result indicating a fire or a power failure, the emergency light extraction unit 43 detects the location of the detection sensor that generated the emergency detection result and extracts an evacuation path. The emergency light extracting unit 43 checks the detection result of the detection sensor 10 stored in the reception panel memory 44 to determine whether the detection result value is an emergency situation. If the detection result value is a numerical value, an emergency situation occurs when it deviates from a predetermined reference value. If the detection result value is On / Off, it is recognized that an emergency situation has occurred.

On the other hand, when the detection sensor 10 transmits the detection result by the broadcasting method, the plurality of emergency exit indicator 20 may receive the detection result and transmit it to the fire receiving panel (40). In this case, the identification of the detection sensor 10 included in the detection result.

When it is recognized that the emergency situation has occurred, the emergency light extraction unit 43 finds the position of the irradiated detection sensor 10 by examining the identifier of the detection sensor 10 which sent the detection result value of the emergency situation. The emergency light extraction unit 43 estimates the location where the emergency situation is detected as soon as an emergency situation occurs and finds an evacuation route.

When the emergency light extraction unit 43 finds an evacuation route, the emergency light control unit 43 transmits emergency indication data to each of the LED emergency exit indicators to indicate the direction of the evacuation route.

Referring to FIG. 6, it is assumed that a fire has been detected in the emergency exit B located on the right side of the building drawing. The evacuation route is therefore in the direction of Emergency Exit Staircase A, located on the left. Therefore, the display direction of the emergency exit indicator 20 installed in the passage is a direction toward the emergency exit A. FIG.

Compared to FIG. 7, which is a conventional emergency exit indicator, emergency exit indicators 53, 54, 55, 56 are referred to in the opposite direction to emergency exit B. FIG. Therefore, the emergency exit indicator 20 according to the present invention can guide the evacuation route more accurately.

When it is recognized that an emergency situation such as a fire has occurred, the emergency alarm transmitter 45 displays the fire position or rings the alarm by wire, and transmits the contents of the fire to related departments such as a fire department and a disaster prevention room. In this case, preferably, the contents of the fire are transmitted wirelessly. Such a transmission method can be performed even without a manager, and there is no operation error of the manager. Since the transmission can be carried out exactly as the program can know the exact location, type, time, etc. of the fire at the fire station.

In addition, in order to solve the problem that the emergency exit indicator is installed in a high place and the direction of the emergency exit is not known because of the smoke generated when a fire occurs, the mounting position of the LED emergency exit indicator 20 according to the present invention is possible in the building wall. Install on the floor or floor of a building. The building is considered to include a tunnel, a subway platform or a passage.

On the other hand, when the LED emergency exit indicator 20 is mounted on the bottom of the wall, the case is made of stainless steel (SUS) material to prevent corrosion (rust).

In addition, when the LED emergency exit indicator 20 is mounted on the bottom, the case includes a transparent tempered glass attached to the front. The LED emergency exit indicator 20 as described above is installed is embedded in the floor so that the LED is directed upward.

In the present invention, a high brightness light emitting diode is used in the LED emergency exit indicator lamp 20. As described above, in the case of using a high-brightness light emitting diode, since the amount of heat generated from the LED is large, it is preferable to provide the cooling fan 100 inside the case as shown in FIG. 8. Since the operation of the cooling fan can be easily performed by a conventional control method, a detailed description thereof will be omitted.

In addition, as shown in Figure 9, the LED emergency exit indicator 20 preferably has a triangular shape when viewed from above the front center is projected and inclined left and right. When installed as described above, even if viewed from the side of the left or right side of the LED emergency exit indicator 20 can be seen well the contents displayed on the indicator. Therefore, even if the pedestrian is far from the left or right of the LED emergency exit indicator 20, it is easy to find the indicator and learn what is displayed on the indicator.

In particular, the LED emergency exit indicator 20 as described above is more preferably installed on the wall surface of the tunnel. Because the vehicle travels at a considerably faster speed than a pedestrian, the driver needs to know the location of the emergency exit from afar, but can slow down and stop before the emergency exit. In addition, if the driver finds an emergency exit in the vehicle in the middle of the tunnel, the emergency exit at the rear of the vehicle should be clearly visible so that the rear view mirror can be seen.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example, Of course, a various change is possible in the range which does not deviate from the summary.

The present invention is to develop a fire reception panel that immediately transmits an emergency situation to a relevant department or institution such as a fire station, a disaster prevention room, and an indicator for guiding people to an emergency exit in an emergency situation such as a fire or a power failure in a building such as a restaurant or a theater or an office.
