Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable emergency lighting apparatus, and more particularly, to a portable emergency lighting apparatus that guides a user to an evacuation route in the event of an emergency.

Due to the development of architectural technology and the high-rise and diversification of buildings, the internal structure of recent buildings, which are designed to utilize the limited area as much as possible, are becoming increasingly complex. Emergency lighting is provided inside the building to allow people to recognize the appropriate escape route in the event of an emergency such as fire or power failure inside the building. In addition, when the emergency situation such as a power failure occurs, a portable portable emergency lighting apparatus is further provided so as to secure a view for moving to the emergency escape path provided with the emergency light.

However, the evacuation route using the conventional emergency light is limited to the technique of controlling the light of the emergency light and informing the evacuation route. In such a case, there is a limit to grasp the position of the emergency light or the like in a place where the internal structure of the building is complicated or a user who visits the specific building for the first time. Furthermore, when the emergency light is located in a blind spot where no emergency light is disposed, it is difficult to provide an appropriate evacuation route, and there is a problem that if a large number of people are concentrated on a specific evacuation route, there is a high possibility of leading to a secondary accident.

Furthermore, since the conventional portable emergency lighting apparatus is limited to merely securing the forward view, there is a limit in that a user who can not maintain his / her peacefulness in an emergency situation can not find a safe escape route by using only the portable emergency lighting apparatus. Therefore, it is necessary to develop a technique to solve such a problem.

In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a view showing a schematic configuration of an evacuation route guidance system 1 using a portable emergency lighting apparatus 100 according to an embodiment of the present invention.

Specifically, the evacuation route guidance system 1000 according to an embodiment of the present invention can be implemented by the external device 100, the portable emergency lighting device 100, and the external device 200.

To this end, the portable emergency lighting apparatus 100 may include at least one light emitting module. Here, the light emitting module may be any one of an LED, an incandescent lamp, and a laser.

Meanwhile, the portable emergency lighting apparatus 100 according to the present invention may perform the function of guiding the evacuation route by detecting an emergency situation, unlike the conventional portable emergency lighting apparatus.

Then, the portable emergency lighting apparatus 200 can guide the user to the direction and angle for moving to the evacuation route provided inside the building based on the received event information. Details related to this will be described later.

The external device 200 may be an apparatus for generating event information to be provided to the portable emergency lighting apparatus 100. Specifically, the external device 200 may be fixedly disposed inside the building to determine whether an emergency situation has occurred. The external device 200 may include at least one sensing sensor, and may determine whether an emergency situation has occurred by using the sensing sensor. For example, the external device 200 may determine that a fire has occurred through the temperature sensor or the smoke sensor if the ambient temperature or the smoke sensing value is equal to or greater than a predetermined threshold value. Alternatively, the external device 200 senses the commercial power supplied to the external device 200, and can determine that a power failure has occurred when the commercial power is shut off. If it is determined that an emergency situation such as a fire or a power failure has occurred, the external device 100 can generate event information for the emergency situation.

Thereafter, the external device 200 can transmit the generated event information to the other external device 200 or the portable emergency lighting device 100. As described above, at least one external device 100 may be provided for each main location in the building. When a plurality of external devices 100 are provided, a plurality of external devices 100 may form a network . In this case, the external device 100 can share the event information with other external devices 100 through the wireless network constructed in advance. The external device 200 can transmit event information in a broadcast manner. When the external device 200 or the portable emergency lighting device 100 located within a communication radius has event information radiated within a communication radius, can do.

The external device 200 may be a stationary emergency light or a wireless AP fixedly disposed inside the building. However, the external device 100 is not limited to the above-described example. The external device 100 may include a sensing module for detecting an emergency situation, a data processing module for generating event information, which is notification information on an emergency situation, And may be replaced with another device having a communication module for transmitting and receiving generated event information through a network.

Fig. 2 is a diagram showing a specific configuration of the portable emergency lighting apparatus 100 of Fig.

The portable emergency lighting apparatus 100 according to an embodiment of the present invention includes a light emitting module 10, a communication module 20, a sensing module 30 and a control module 40. Such a portable emergency lighting apparatus 100 may be implemented by a greater number of components than the components shown in FIG. 1, or may be implemented by fewer components.

The light emitting module 10 may be a device for providing a light source. The light emitting module 10 can turn on or off the light source according to the operation of the switch provided in the portable emergency lighting apparatus 100 or change the illuminance or the light emission pattern of the light source by the control module 40 described later. The light emitting module 10 may include at least one module of modules that provide various light sources such as LEDs, incandescent lamps, lasers, and the like.

The communication module 20 can perform wireless communication with the external device 200 constituting the wireless network. The communication module 20 can receive event information about occurrence of an emergency situation from the external device 200 through wireless communication. As described above, the external device 200 can detect the emergency situation, generate the event information, and transmit the event information through the broadcasting method. At this time, the communication module 20 can receive event information radiated from any one of the external devices 200 located within the communication radius.

The sensing module 30 can measure the position information and the azimuth angle when the event information is received. Specifically, the sensing module 30 may periodically measure the current position information of the portable emergency lighting apparatus 100 when the event information is received. At the same time, the sensing module 30 can periodically measure the azimuth angle with respect to which direction the light emitting module 10 is facing. To this end, the sensing module 30 may comprise a plurality of sensor modules. Here, the sensing module 30 may include a position sensor 31 for sensing the position information of the apparatus and a rotation sensor 32 for sensing the three-dimensional rotation information of the apparatus.

The sensing module 30 can measure the current position of the portable emergency lighting apparatus 100 through the position measurement sensor 31. [ At this time, the position measurement sensor 31 can measure the real-time position of the portable emergency lighting apparatus 100 using any one of various known positioning techniques. For example, the position measurement sensor 31 can periodically measure the position of the portable emergency lighting apparatus 100 using GPS. As another example, the position measurement sensor 31 may measure the distance information to at least one external device 200 located in the periphery, and may calculate the position information based on the measured at least one distance information. For example, the position measurement sensor 31 measures distance information on the basis of the intensity of a signal received from three external devices 200 located nearby, and measures the three measured distance information using a triangulation method The current position of the emergency lighting apparatus 100 can be calculated.

The sensing module 30 measures the direction of the portable emergency lighting device 100 through the rotation sensor 32 such as a gyro sensor or a geomagnetic sensor to detect the direction of the portable emergency lighting device 100, The azimuth angle can be measured.

The control module 40 can guide the portable emergency lighting apparatus 100 to examine the evacuation path direction. To this end, the control module 40 may utilize an emergency evacuation map reflecting at least one evacuation path.

Emergency evacuation plan is a structural diagram of a specific building. Facilities for escape from the building (emergency exit, emergency stairs, etc.) and emergency facilities (fire hydrant, breaker, etc.) may be displayed when an emergency occurs. Also, the emergency evacuation route can be managed by displaying the evacuation route to escape to the outside of the building in an emergency situation. The emergency escape route reflecting the at least one evacuation route may be included in the event information received from the external device 200 or may be received when the communication module 20 initiates communication with the external device 200, And may be stored in advance in the database unit of the lighting apparatus 100. [

At this time, the control module 40 can determine, based on the positional information measured by the sensing module 30, the position of the portable emergency lighting apparatus 100 in the emergency escape route. At the same time, the control module 40 determines whether the portable emergency lighting apparatus 100 investigates the evacuation path direction provided in the emergency evacuation route at the current position in the emergency evacuation map, based on the azimuth angle measured by the sensing module 30 It can be judged. Thereafter, the control module 40 controls the illuminance or the emission pattern of the light source according to whether or not the portable emergency lighting apparatus 100 investigates the direction in which the escape route is located on the emergency escape route reflecting the at least one escape route And transmits the generated control signal to the light emitting module 10. A concrete description related to this will be described later.

Fig. 3 is a diagram showing a specific method by which the portable emergency lighting apparatus 100 of Fig. 1 guides the evacuation route.

As described above, the control unit 40 of the portable emergency lighting apparatus 100 can determine where the portable emergency lighting apparatus 100 is located in the emergency escape route. For example, the control unit 40 can coordinate the location of the main facility including the external device 200, the emergency stairs, and the like disposed in the emergency escape route. Then, it is possible to perform indoor positioning of the portable emergency lighting apparatus 100 by analyzing the intensity of a signal received from at least one external device 200. The control unit 40 can project the positional information of the portable emergency lighting apparatus 100 on the coordinate emergency escape route on the basis of which the portable emergency lighting apparatus 100 can be positioned in the emergency escape route . However, the indoor positioning method of the control unit 40 is not limited to the above-described method, and it is possible to measure the real-time position of the portable emergency lighting apparatus 100 using any one of various known indoor positioning techniques .

The control unit 40 determines the direction in which the light emitting module 10 of the portable emergency lighting apparatus 100 irradiates the current position in the emergency evacuation direction using the azimuth angle measured by the sensing module 30 .

On the other hand, the control unit 40 can further measure the reference azimuth angle with respect to the direction in which the escape route is formed, based on the current position of the portable emergency lighting apparatus 100. [ More specifically, the control unit 40 can calculate the reference azimuth angle by comparing any one of the areas constituting the escape route with the current position of the portable emergency lighting apparatus 100. [ For example, the control unit 40 coordinates the current position of the portable emergency lighting apparatus 100 and the area constituting the evacuation route within the emergency evacuation map, and sets the position of the portable emergency lighting apparatus 100 100) from the current position. The control unit 40 can calculate the reference azimuth using the first coordinate of the current position of the portable emergency lighting apparatus 100 and the second coordinate of the position closest to the current position of the emergency lighting apparatus 100. [ As another example, the control unit 40 may calculate an average coordinate value of a plurality of coordinates forming the evacuation route, and utilize the calculated average coordinate value as the second coordinate. As another example, the control unit 40 may extract the coordinate information for the main facility (emergency exit, emergency stairway, etc.) connected to the evacuation route, and utilize the extracted coordinate information as the second coordinate.

Thereafter, the control unit 40 can determine whether the portable emergency lighting apparatus 100 investigates the evacuation route at the current position based on the reference azimuth angle and the azimuth angle. Specifically, the control unit 40 calculates the difference value between the reference azimuth angle and the azimuth angle, and when the calculated difference value is within the predetermined threshold range, the portable emergency lighting apparatus 100 moves in the direction in which the evacuation route is prepared It can be judged that the light source is being investigated. On the other hand, when the calculated difference value is out of the predetermined threshold range, the control unit 40 can determine that the portable emergency lighting apparatus 100 is irradiating the light source in a direction different from the direction in which the evacuation path is provided at the current position . Here, the control unit 40 may control the illuminance or light emission pattern of the light source emitted from the light emitting module 10 depending on whether the portable emergency lighting apparatus 100 irradiates the direction in which the escape path is provided at the current position.

4 to 6 are diagrams showing an example in which the light emission pattern varies according to the irradiation angle of the portable emergency lighting apparatus 100 of FIG.

Specifically, the control unit 40 can control the portable emergency lighting apparatus 100 to function as a general lighting apparatus at normal times. That is, if it is determined that the event information is not received, the control unit 40 can control the light emitting module 10 to irradiate the light source according to a predetermined illuminance. At this time, when the event information is received by the portable emergency lighting apparatus 100, the control unit 40 may compare the difference between the reference azimuth and the azimuth with a preset threshold range as described above. The control unit 40 can control the light emitting module 10 to emit light at a normal illuminance (predetermined illuminance) or more when the calculated difference value is included in a predetermined threshold range. Hereinafter, the above-described contents will be described in more detail with reference to FIGS. 4 to 5. FIG.

4, the controller 40 calculates a difference value between the azimuth angle and the reference azimuth angle and compares the calculated difference value with the threshold range, and when the difference value is within the critical range, the light emitting module 10 sets the first roughness value The light source can be controlled to emit light. The control unit 40 may control the light source irradiated by the light emitting module 10 to be irradiated with the first light emission pattern.

On the other hand, as shown in FIG. 5, the controller 40 can control the light emitting module 10 to emit the light source with the second illuminance value when the calculated difference value is out of the threshold range. Alternatively, the control unit 40 may control the light source irradiated by the light emitting module 10 to be irradiated with the second light emission pattern.

At this time, the first illuminance value may be set to have a value larger than the second illuminance value. For example, the first light emission pattern is a pattern in which the light source is always irradiated, and the second light emission pattern is a pattern in which the light source is blinking at a predetermined time interval, and the first light emission pattern and the second light emission pattern are different from each other. . In some cases, the second illuminance value is set to have a value larger than the first illuminance value, and both the first emission pattern and the second emission pattern may be set so that the light source has a blinking pattern. In this case, the first light emission pattern and the second light emission pattern may be set so that the time intervals at which the light sources blink are different from each other.

4 and 5, the illumination value or the light emission pattern of the portable emergency lighting apparatus 100 according to the present invention in the case where the direction of illuminating the light source at the current position is the direction in which the escape path is provided, The direction of irradiating the light source at the current position may be set to be differentiated from the illuminance value or the light emission pattern when the direction is opposite to the direction in which the escape path is provided.

On the other hand, the first illuminance value and the second illuminance value may be set to be higher than a predetermined illuminance. That is, as the portable emergency lighting apparatus 100 irradiates a direction opposite to the direction in which the evacuation path is provided, the illuminance of the light source emitted from the light emitting module 10 is controlled to be lowered, but the lower illuminance value does not cause an emergency Or more than the generally provided illuminance.

In some other embodiments, the controller 40 may compare the difference between the reference azimuth and the azimuth with a plurality of critical intervals that are not in the critical range. In this case, the controller 40 checks the calculated difference value to determine the interval of the plurality of critical sections, and controls the light emitting module 10 so that the illuminance value of the light source irradiated from the light emitting module 10 Can be adjusted. In other words, the control unit 40 controls the illuminance of the light source emitted from the light emitting module 10 to gradually increase as the calculated difference between the reference azimuth angle and the azimuth angle becomes smaller, and when the calculated difference value becomes larger, As shown in FIG.

Referring to FIG. 6, there is shown another embodiment in which the emission pattern varies according to the irradiation angle of the portable emergency lighting apparatus 100 of FIG.

In this case, the light emitting module 10 of the portable emergency lighting apparatus 100 according to another embodiment of the present invention may include the first light emitting unit 11 and the at least one second light emitting unit 12.

The first light emitting unit 11 may be a lighting apparatus performing a function similar to the light emitting module 10 described above. That is, the first light emitting unit 11 may be a device for irradiating a light source forward to provide a visual field to a user. On the other hand, the second light emitting unit 12 may be a device that emits light only in a specific situation.

Specifically, the second light emitting unit 12 can be controlled to emit light by the control module 40 depending on whether the portable emergency lighting apparatus 100 according to the present invention irradiates the evacuation path direction. That is, the control module 40 can control the first light emitting unit 11 to emit light only when it is determined that the portable emergency lighting apparatus 100 irradiates the direction in which the escape path is provided at the current position in the emergency escape route . On the other hand, when the angle at which the portable emergency lighting apparatus 100 irradiates the light source is greater than or equal to a predetermined angle from the direction in which the evacuation path is provided, the control module 40 determines that the evacuation path direction is not irradiated, And the second light emitting unit 12 are caused to emit light together. For example, when the first light emitting unit 11 is an LED lamp and the second light emitting unit 12 is a laser lamp, the control module 40 determines that the portable emergency lighting apparatus 100 is facing the evacuation path direction If it is confirmed, only the LED lamp can be controlled to be turned on. If the control module 40 determines that the portable emergency lighting apparatus 100 is examining a direction different from the direction in which the evacuation path is provided, the control module 40 can inform the user that the laser light is directed to the wrong direction.

At this time, if a plurality of second light emitting units are provided, the control unit 40 can selectively operate the plurality of second light emitting units to guide in which direction the evacuation path is provided.

To this end, the second light emitting unit 12 may include a plurality of directionally guided light emitting units 12_1 and 12_2. As shown in the drawing, the directionally guided light emitting units 12_1 and 12_2 may be provided on the left and right sides, respectively, with respect to the first light emitting unit 11. In this case, the controller 40 controls the first direction induced light emitting unit 12_1 and the second direction induced light emitting unit 12_2 to emit light so that the evacuation path is shifted in either the left or right direction It is possible to provide information as to whether or not it is provided.

Specifically, the control module 40 can set the angle with respect to the evacuation path around the current position of the portable emergency lighting apparatus 100 to the reference direction (similar to the above-described reference azimuth angle). The control module 40 compares the azimuth angle measured by the sensing module 30 with the reference direction to determine in which direction the evacuation path is formed based on the azimuth angle. In the illustrated embodiment, the evacuation route is provided on the right side with respect to the current direction of the portable emergency lighting apparatus 100. Therefore, the control module 40 can control to emit only the second direction-induced light-emitting unit 12_2 disposed on the right side of the first light-emitting unit 11 among the two directionally-guided light-emitting units 12_1 and 12_2. According to the control procedure described above, the wall surface irradiated with the light source is irradiated with the LED light emitted by the first light emitting unit 11 and the second light emitted by the second direction guided light emitting unit 12_2, Laser illumination can be displayed. As a result, even if a user who uses the portable emergency lighting apparatus 100 according to the present invention is in a situation where it is difficult to secure a view, such as a power failure, by simply identifying the pattern of the light source displayed on the wall surface, Information on whether or not it is available can be easily provided.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
