Description

Fire evacuation route guidance system and method

The present invention relates to a fire evacuation route guidance system and method.

In general, when a fire occurs, an eyewitness reports the fire to the fire department, presses the fire alarm emergency bell provided in the building, or alerts the alarm by recognizing a fire detection sensor installed in the building. According to this, there is a considerable difficulty in recognizing the state of the fire point in real time and safely evacuating the people in the building, so it is required to have a device for preventing fire in a building or apartment or an appropriate device for quick response in case of a fire. .

Recently, due to the increase in the size of buildings, the increase in height and complexity of buildings, a method of operation and management using various fire response systems has been introduced. A detection sensor is installed, and the detection sensor is connected to the central control room and control room to operate the alarm system and at the same time let the manager know.

However, even such a conventional fire response system does not provide an appropriate evacuation route according to the location of the fire, and only provides a warning broadcast indicating that a fire has occurred. In other words, it is not possible to provide an appropriate evacuation route according to the fire occurrence point and the spread of the fire, resulting in a lot of confusion for people in the building to safely evacuate. Due to the structure of the building, evacuation routes such as emergency doors that people located in each room must use may be different, so it is necessary to provide an evacuation route suitable for each room and section. That is, there is a need to provide a safe evacuation route because evacuation routes such as emergency doors that people should use may be different depending on the ignition location and the structure of the building.

1 is a block diagram illustrating the configuration of a fire evacuation route guidance system according to an embodiment of the present invention, and FIG. 2 shows an installation method of route beam devices for indicating an evacuation direction according to an embodiment of the present invention. It is one example diagram.

1, the fire evacuation route guidance system according to the present embodiment includes a plurality of fire detectors (10-1, ..., 10-n, hereinafter referred to as 10), a plurality of route beam devices (20-) 1, ..., 20-m, hereinafter collectively referred to as 20) and a control device 30 .

The fire detector 10 is a means for detecting fire, such as a smoke detector and a heat detector, and is provided at each place inside the building to detect the fire. And, since the fire detector 10 has each network address, the control device 30 can identify each fire detector 10 . Accordingly, when any fire detector 10 detects a fire and transmits a fire signal to the control device 30 , the control device 30 identifies the fire detector 10 to confirm the location of the fire.

The path beam device 20 displays a preset evacuation direction with a beam on the floor (or wall). For example, as a device that displays a specific screen on the floor, such as a head-up display (HUD), an LED logo beam that displays advertisements on the floor, each path beam device 20 displays its own evacuation direction. .

Referring to FIG. 2 showing an example, the path beam devices 20 are each set in their own evacuation direction, so the control device 30 selects and operates the path beam devices 20 corresponding to the evacuation path. do. According to this embodiment, each of the path beam devices 20 displays only one unique direction, rather than a method of selecting and displaying a plurality of these directions as needed, so that the evacuation direction is incorrectly displayed due to problems such as failure. Solve problems that arise at the source.

And, as shown in the figure, each of the path beam devices 20 is installed adjacent to and intersecting between those indicating different evacuation directions. For example, the first path beam device 20-1 and the second path beam device 20-2 immediately adjacent to each other guide different directions, and similarly, the third path beam device 20-3 directly adjacent to the second path beam device 20-3 It is installed to guide an evacuation route different from the beam device 20-2.

When a fire signal is received, the control device 30 detects a fire, identifies the fire detector 10 that has transmitted the fire signal, confirms the location of the fire, determines the evacuation route according to the location of the fire, and determines each path beam device 20 ) to control their operation.

3 is a flowchart illustrating a fire evacuation route guidance process performed in the control device according to an embodiment of the present invention.

Referring to FIG. 3 , when the control device 30 receives a fire signal from an arbitrary fire detector (S310), the fire detector is identified by using an ID or a network address (such as an IP address or address). Check the location of the fire (S320).

The evacuation route is determined at each location inside the building using the fire location and the structure of the building (passage, emergency exit, stairwell, etc.) (S330). Since the determination method of the evacuation route corresponding to the fire location will be apparent to those skilled in the art, a more detailed description thereof will be omitted.

When the evacuation route is set, the driving of each route beam device is controlled accordingly (S340). Referring to FIG. 2, for example, if the evacuation route is from right to left, the second path beam device 20-2 is not driven, and the first path beam device 20-1 and the third path beam The device 20-3 is driven and controlled to indicate the evacuation direction.

4 is a front sectional view showing the configuration of a path beam device for performing multi-display using a reflector according to an embodiment of the present invention, and FIG. 5 is an evacuation using a reflector of the path beam device according to an embodiment of the present invention. It is an exemplary diagram illustrating a multi-directional display method.

The path beam apparatus according to the present embodiment uses one beam module (eg, one LED and a lens on which information to be displayed is printed) to project two beam images to be displayed at different positions.

Referring to FIG. 4 showing the configuration according to this, the path beam device includes a beam module 410 , a reflector 420 , and an angle adjustment module 430 .

The beam module 410 emits a beam image 440 that is information to be displayed as a beam.

Referring to FIG. 5 together, the beam image 440 emitted from the beam module 410 is divided into a first display area and a second display area by the bent-shaped reflector 420, and the positions 440 - 1 and 440 respectively. -2) is displayed. Accordingly, the same evacuation direction is displayed at two distant locations by a single path beam device.

According to this embodiment, by displaying the same evacuation direction at positions spaced apart from each other using a single path beam device, it is possible to guide the evacuation route in a wider range so that a large number of people can recognize the evacuation direction.

The angle adjustment module 430 is for adjusting the bending angle of the reflector 420 . As shown in the drawing according to an example, the angle adjustment module 430 changes the angle of the reflector 420 in a manner that the rod connected to the bent edge of the reflector 420 is raised or lowered by using a motor.

6 and 7 are flowcharts and exemplary diagrams illustrating a process of controlling failure occurrence of path beam devices according to an embodiment of the present invention.

Referring to FIG. 6 , after performing control of the path beam devices, the control device 30 checks the presence or absence of failure of each path beam device. According to an example, the control device 30 may analyze images by CCTV cameras installed on each passage of a building to determine whether each path beam device operates normally (S610). Of course, the present invention is not limited thereto, and it is also possible to check whether a normal operation is performed by receiving a response signal from each of the path beam apparatuses.

Alternatively, each of the path beam devices performs short-range communication with the adjacent path beam devices through Bluetooth, thereby confirming the presence or absence of each other's failures. For example, the first path beam device 20-1 performs short-distance communication with the second path beam device 20-2 and/or the third path beam device 20-3 to obtain information on whether or not the device operates normally. and reports the related information to the control device (30).

It is determined whether there is an obstacle path beam device (S620), and if there is, an adjacent path beam device displaying the same direction as the faulty path beam device changes the bending angle of the reflector 420 to provide two evacuation directions. Control to widen the display interval of (S630).

Referring to FIG. 7 together, when a failure occurs in the first path beam device 20-1, the third path beam device 20-3 displaying the same direction changes (reduces the angle) the bending angle of the mirror. Make the distance between the marked positions in the two evacuation directions to be separated.

Here, in the drawing, the angle of the reflector 420 is adjusted so that the display positions of both the first display area and the second display area are changed. It may be possible to change only the display position of the corresponding first display area by changing the angle of the reflector only in part.

According to this embodiment, the evacuation direction can be stably displayed in a wider range by covering even the area corresponding to the path beam device in which the fault has occurred using another normally operating path beam device. In other words, by setting a unique direction guidance for each path beam device and expanding the display range of each device in case of some obstacles, more stable evacuation direction guidance can be performed in preparation for some obstacles.

The fire evacuation route guidance method according to the present invention described above may be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes any type of recording medium in which data that can be read by a computer system is stored. For example, there may be a read only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like. In addition, the computer-readable recording medium may be distributed in computer systems connected through a computer communication network, and stored and executed as readable codes in a distributed manner.

In addition, although the above has been described with reference to the preferred embodiment of the present invention, those of ordinary skill in the art can use the present invention within the scope not departing from the spirit and scope of the present invention described in the claims below. It will be understood that various modifications and variations are possible.
