Description

Smart emergency light system with guidance function using laser

The present invention relates to an emergency light, and in detail, when various disasters, including fires, occur in various facilities, and can be identified even in a smoke-filled state by using a laser so as to quickly and safely evacuate the distress people inside the facilities. The present invention relates to a smart emergency light system having an evacuation function using a laser that outputs an alarm and delivers a site image to an administrator so as to evacuate the location of a fire or toxic gas.

In general, a disaster such as a fire causes a large amount of smoke and soot along with a toxic gas that is fatal to the human body, causing the refugee to be in danger. Particularly, a fire in an indoor space such as a public building or a subway used by a large number of people is not allowed. With the use of enclosed structural features, many people are likely to lead to large casualties.

In order to minimize human accidents in the event of such a disaster, it is most desirable to evacuate to a safe outdoor area as soon as possible. Therefore, an emergency equipment for evacuation is required to guide the direction of emergency exit so as to escape from a dangerous situation in which toxic gas is generated.

The relevant legislation is to equip public places with the appropriate number of emergency equipments. Especially, in an indoor place such as a narrow corridor, emergency lights are installed in easy-to-check locations so that escape routes such as emergency exits can be easily identified.

However, due to the large area and the complicated structure, the conventional multi-use facility is difficult to identify the location of the emergency light in a disaster situation, and the direction of the fire or the emergency exit is lost because the smoke is lost in the room filled with smoke caused by the combustion of various interior materials. If you move to a place where you are not, you are often in great danger.

In addition, conventionally, only the power failure situation is taken into account, so that the emergency power emits light with relatively low intensity or light through luminous material, so that the devices for guiding the emergency exit often fail to serve as a state full of smoke. An improvement was required.

The emergency light 120 is a function to display the location of the emergency exit at all times in the present invention, the monitoring module unit 110 to propagate the information for evacuation with people in the facility or building with disaster information such as fire. Similarly, an individual ID is designated and installed on the location of the exit area of the facility, in particular, in the emergency exit position. The laser oscillator 121, the memory 122, the camera 123, the light emitter 124, the speaker 125, and the microphone 126 are installed. And a first control unit 127, a distance calculation unit 128, an interlocking unit 129, a communication unit 131, a rotation unit 136, and an encryption unit 137.

The emergency light 120 may be formed in various forms, but as shown in FIG. Is installed in position.

The laser oscillator 121 is configured to emit a laser beam to the front of the emergency light 120, in the present invention is to significantly improve the identification power during a disaster through the laser beam basically. Although it is possible to guide the direction of the emergency exit through a single laser beam, it is preferable to emit the laser beam through a plurality of light emitting laser diodes so that it can be easily checked even in a relatively long distance or in a smoky situation. In particular, it is preferable to use the green laser in the 532 nm wavelength range having excellent visibility among the laser beams, and it is also possible to use a plurality of laser beams to form an arrow-shaped spot or other guide marker for the evacuation direction.

The rotating unit 136 is an electric actuator that rotates the laser oscillating unit 121 in a set direction, and rotates the laser oscillating unit 121 in up, down, left and right directions within a set angle range to guide the direction so that the evacuator can easily determine the escape direction. To be able.

The memory 122 stores an alarm signal including a sound according to a disaster type. As mentioned, a disaster type is basically a fire, which can be an earthquake, flood, or flooding, depending on the characteristics of the facility, such as an earthquake, terrorism, and the like, as needed. A sound for informing such a disaster type is prepared in advance and stored in the memory 122 as an alarm signal, and is made by expressing the location of the current emergency exit, the occurrence location of the disaster, the escape route, and the like as a sound.

The camera 123 is configured to acquire an image by photographing the front lower side, and may acquire an image in real time by photographing an inside of a passage or a space where an emergency exit is located. In a relatively long corridor space, the angle of view can be smoothly photographed to the end of the corridor. In a short space, blind spots can be minimized by using a wide-angle lens. Through the camera 123, it is possible to monitor the video in the visible area in which the emergency light 120 is installed and determine a relief signal according to the fire (disaster) occurrence situation or the emergency situation of the evacuator through the image.

The light emitting unit 124 basically consists of a plurality of LEDs to emit light in a color and a pattern designated by an alarm signal, so that the emergency light 120 can be easily found and accessed even in darkness or smoke.

Correspondingly, the cover 130 having the emergency exit sign painted as a transparent or translucent material is installed on the front of the light emitting part 124. As the light emitting part 124 emits light, the sign drawn on the cover 130 is bright. And works to be discernible.

In general, as the emergency exit sign is displayed in green, not only LEDs emitting green light but also LEDs of red, yellow, and blue colors can be easily distinguished by colors, and the arrangement of the LEDs is regular. It is configured to display simple letters and numbers through selective lighting.

The speaker 125 outputs an acoustic alarm signal and guide sound at a set volume to assist in the delivery of disasters and guidance information through sounds in a situation where an uncomfortable refugee or a vision is difficult to secure, and the call unit 145 described later. When implementing the call function through the control unit 140 plays a role of receiving and outputting the voice of the manager.

In addition, the microphone 126 may perform a security function by collecting the sound generated in the field even if it is not in a disaster situation, and may be used for grasping an emergency situation through the collected sound.

The first control unit 127 is a control circuit for controlling the electrical / electronic configuration provided in the emergency light 120 by receiving power, the light emitting unit 124 and the speaker 125 according to the normal mode or the alarm signal. The control unit transmits the obtained image and audio signals to the control unit 140.

Through a series of detailed configurations of the emergency light 120 can not only solve the problem of the conventional one-dimensional disaster alarm system that simply operated the emergency bell, but also can be easily added to the existing system for human safety.

5 is a conceptual view showing a laser emission form according to an embodiment of the present invention, which is basically provided with a plurality of laser oscillation units 121, but may utilize a method of emitting lasers to different positions, but embodiments of the present invention. In the emergency light 120 further includes a rotating part 122 for rotating the laser oscillation part 121 in a set direction, the laser oscillation part and the rotating part is provided with a plurality may be capable of simultaneously emitting a plurality of lasers at different distances. The emergency light 120 further includes a distance calculating unit 128 that recognizes a plurality of laser beams through the camera, calculates a distance in the image, and displays the image in the image. It is possible to see how far the evacuation person or object is from the emergency exit.

In addition, by controlling each of the plurality of laser oscillation unit 121 and the rotating unit 136 is provided so as to individually control the laser output angle for each laser oscillation unit 121, the emergency light 120 is an alarm Each laser oscillator 121 and the rotating unit 122 are continuously controlled in response to a signal to output at regular intervals on the front surface or to move the laser beam at a set angle to output the laser in a single direction. By continuously converting to, the identification power can be improved by promoting the scattering of the beam through the mist.

In addition, the emergency light 120 receives a control signal transmitted through the control unit 140 so that a terminal possessing a Bluetooth function as a terminal possessed by the evacuator can receive and guide information as the emergency light 120 approaches. The communication unit 131 may further include a communication unit 131 which converts the refugee so as to check through the terminal possessed by the evacuator and transmits the Bluetooth 4.0 based broadcasting scheme.

In order to implement such an additional function, the evacuator must possess a terminal, and it is necessary to activate the Bluetooth function in a state in which an application to which access is granted is installed in advance.

Of course not even Bluetooth WiFi  In addition, various short-range wireless communication methods may be applied. We can also extend it At each emergency exit  It can be configured to send and receive information by forming a wireless network between the same floor for a plurality of emergency lights installed. This prevents the communication from being disconnected due to damage, breakdown, fire, etc., so that the evacuation can be made smoothly. Such a wireless network can be connected to each other in 100m units. Waipa 2, Bluetooth function Stay intact  Can be. Especially Wi-Fi Bluetooth is a short-distance communication network, so if you need to use an auxiliary device such as an amplifier when a long distance is necessary, the entire system may become inoperable according to the breaker breakage when using a repeater. Mutual  Data can be sent and received to prevent this problem.

In addition, the emergency light 120 may be provided with an interlocking unit 129 provided with an IP address and configured to connect to an external Internet network to provide a video detection and communication function through connection and communication from an approved external terminal. . Through the interlocking unit 129, the terminal and emergency light 120, which is pre-approved by the manager or the fire control agency, may be visually sensed through the evacuees on the scene by detecting and talking to each other.

At this time, in order to prevent hacking or unauthorized access from the terminal other than the approved external terminal, the authentication means such as a password that can be connected to the emergency light 120 is encrypted and stored in the blockchain server and connected with the authenticated terminal. By configuring the encryption unit 137 to approve can greatly improve the security.

The control unit 140 is connected to the monitoring module 110 and the emergency light 120 and wired or wireless to control the disaster situation of the facility, the database 141 and the monitoring unit 142 and the second control unit ( 143) and a detailed configuration of the alarm transmission unit 144 and the call unit 145, may be installed in the form of a separate management server in the remote location, and in some cases included in each emergency light 120 in whole or in part It may be installed in the form.

The database 141 is configured to store the evacuation information including the area information and the structure of the facility, the emergency exit location and the movement path where the monitoring module 110 and the emergency light 120 are installed. As mentioned above, as the monitoring module unit 110 and the emergency light 120 are provided with individual IDs, the detection positions of the monitoring module unit 110 and the emergency light 120 may be determined and individual communication may be performed.

The location of the emergency exit provided in the facilities and the respective locations in each area in the state that the installation position of each monitoring module 110 and evacuation information module unit 120 on the structural information of the entire facility to which the present invention is applied is previously identified for each zone The entire path that can be moved to the emergency exit can be arranged in advance in consideration of the number of all cases to build the database 141.

The monitoring unit 142 collects the detection signal of the monitoring module unit 110 and the video and audio signals of the emergency light 120 and is configured to identify the type of disaster and the location of occurrence, each monitoring module unit 110 and It is always connected to the emergency light 120 and collects and monitors signals, and when a disaster type input is detected through a video or audio signal collected from a specific monitoring module 110 or the emergency light 120, The location of the occurrence of the monitoring module 110 or the emergency light 120 that sends a signal is identified.

The second control unit 143 reflects the type of disaster and the location of the emergency identified through the monitoring unit 142 to determine the type of occurrence and the control signal of each emergency light 120 and the acoustic alarm signal and the guidance signal to be output. It generates a control signal including and may calculate the optimal movement path for each zone through the analysis of the database 141 as necessary.

That is, the light emitting unit 124 generates a control signal for outputting the type of disaster and the location of occurrence in a distinctive color and lighting pattern as well as simple texts, and outputs an image and sound alarm signal and guidance through the speaker, respectively. Generate a control signal comprising the signal. In addition, the optimal movement path mentioned may be derived by analyzing the path based on the shortest distance to the emergency exit basically without any risk factors such as flame or smoke on the movement path.

In addition, by generating a control signal for the angle control of the rotating unit 122 for each emergency lamp 120 to greatly improve the visibility through the laser as well as the light emitting unit 124.

Since the general disaster occurrence position is unchanged for all zones, the images and sounds for guiding the disaster type and the occurrence position are outputted in the same manner as all emergency lights 120 installed, but the movement paths are different for each zone, so The control signal or the guide signal for driving the rotating unit 122 needs to be generated to reflect the position of each zone.

In response, the second control unit 143 reflects the detection results of the first sensor 112 and the second sensor 113 to reflect the distribution of smoke and gas and the direction of movement for each zone. It is equipped with an algorithm that can calculate the movement route to minimize the exposure time so that the choking accident can be minimized.

The alarm propagation unit 144 is configured to deliver the control signal generated by the second control unit 143 to each corresponding emergency light 120 is accurately transmitted through the individual ID given to each emergency light 120, Refugees may be informed of their route of escape based on their current location.

The call unit 145 is configured to operate as a refugee selects a call function through the operation unit 125 and provides a call function through the microphone 126 and the speaker 125 provided in the corresponding emergency light 120. In the case where the control unit 140 exists together with the manager at a remote location, the evacuation person and the manager of the area may make a phone call and receive notification of a disaster situation or guide the development of a movement route. In addition, if necessary, a function of transmitting a guide broadcast to all the remaining emergency lights 120 through the control unit 140 in the form of voice broadcasting through one emergency light 120 may be implemented.

Through such a series of configurations, evacuees located in each zone receive information on the detected disaster location and at the same time, the emergency route 120 installed in each zone provides video and audio information on the location of the disaster and provides a route for evacuation. Guidance may be made.

In the following description, in order to prevent the gist of the present invention from being blurred, detailed descriptions of the same functions and configurations as those of the first embodiment will be omitted and the description will be focused on the additional configuration.

In a situation where smoke is full due to a normal fire, even if the brightness of the laser oscillation unit 121 and the light emitting unit 124 is bright, visibility may be greatly reduced, which may cause a situation in which an evacuator cannot easily find it. Of course, it is possible to guide through the sound output through the speaker 125, but even in a situation where the disaster is accompanied by ambient noise, this may not be even effective. An air blower 132 and a sprayer 133 may be provided on the side surface of the emergency light 120.

The blower 132 is provided with a small powerful fan to exhaust the strong air to the front of the laser oscillator 121 to push the soot and widen the visible range of the laser. Preferably, rather than venting air in one direction, it is necessary to add wings to control the flow of air to generate vortices and to widen the range of laser propagation into the smoke.

In addition, the spraying unit 133 includes a container 134 in which a liquid such as water is accommodated so as to reduce a part of the soot component, and sprays the liquid discharged from the container 134 to the air blowing unit 132 to generate a laser. The soot component forming the mist within the output range is reduced. Although various modifications are possible, the solenoid valve 135 may be installed to open and close the nozzle and the nozzle to the front of the blower 132 in a state in which the inert gas and the liquid are pressurized and filled in the container 134, but the blower may be By opening the solenoid valve 135 during the operation of the 132, the liquid may be naturally sprayed through the internal pressure of the container 134 to form a mist.

At this time, by moving the laser beam output through the rotating unit 136 at a predetermined angle to continuously convert the angle of the laser beam rather than outputting the laser in a single direction to promote the scattering of the beam through the mist to improve the identification power Can be.

In addition, due to the recent fine dust Air quality  Due to the degradation problem, various indoor spaces Process cleaner  As there are many installations, a third sensor 138 capable of measuring fine dust concentration may be installed in the emergency light 130. In particular, the emergency light 130 is installed on the entrance side can easily check that the fine dust from the outside when entering, and in conjunction with the above-mentioned configuration of the communication unit 131, air purifier or through the installed through the short-range communication such as Bluetooth or Air cleaning  Measured by the third sensor 138 while connected to the system Air quality  When confirmed as bad Air cleaning  This can help to ensure efficient indoor air purification in poor air quality.
