Description

FIELD FIELD FIELD FIELDING FIELD [0001]

FIELD OF THE INVENTION The present invention relates to a fire fighting area visualization system and method.

It is essential to arrange fire fighting facilities such as fire extinguishers, fire hydrants, fire brigades, etc. for use in fire, as well as land and sea structures, in ships and offshore structures.

Fire extinguishers are fire extinguishers that fire the fire extinguisher after the user carries it to the fire point at the beginning of the fire.

On the other hand, fire fighting huts for storing fire hoses are fire fighting equipment installed inside the fire hydrant or disposed around the fire hydrant. When a fire occurs, the user opens the fire hose, connects the fire hose to the fire hydrant, and extends the fire hose to the fire area. The fire hose is sprayed to the part where the fire is generated to suppress the fire.

1, since the fire hose stored in the fire fighting box 110 has a limited length, it is generally assumed that the length of the fire hose from the fire hydrant in the fire fighting box 110 is a radius (R) The area inside the circle is regarded as the fire limit 120 (see FIG. 1).

However, when a fire occurs in the left area of the illustrated commercial building, it is within the fire limit 120 centered on the fire hydrant of the fire box 110. However, when the fire hose is extended to the fire position 130, Since the outer wall functions as an obstacle, the fire hose must extend along the travel path as in (1).

In this case, the fire hose can not be extended to the ignition position 130 due to the limit of length, thus causing the failure of proper fire suppression.

FIG. 2 is a block diagram of a fire fighting area visualization system according to an embodiment of the present invention, and FIG. 3 is a view for explaining a fire fighting limit setting process according to an embodiment of the present invention.

Referring to FIG. 2, the fire area visualization system 200 may include a storage unit 210, an image analysis unit 220, a fire protection facility selection unit 230, and a visualization unit 240.

In the storage unit 210, map information for each area, fire fighting ship characteristic information, and the like can be stored. The map information may be, for example, at least one of a regional design drawing, an area map, and the like. The fire fighting characteristics information may include, for example, information on fire hoses of various lengths, fire hydrants of various water pressure, and the like.

Further, the storage unit 210 may further store the fire-fighting equipment selection information (for example, the installation position information of the selected fire-fighting box, the characteristic information of the selected fire-fighting box, etc.) generated by the fire-fighting equipment selection unit 230 to be described later (Map information in which a fire fighting facility (for example, fire fighting box, fire hydrant, fire extinguisher, etc.) is disposed) generated by the visualization processing unit 240 to be described later may be further stored.

 The image analysis unit 220 performs recognition of obstacles (e.g., walls, electric poles, etc.) and travel paths in the map image corresponding to the map information, recognition of the fire limit 120 corresponding to the selected area, And generates analysis information (refer to (a) and (b) of Fig. 3)

The fire protection limit 120 may be previously set individually for each area of the map information, or may be set to a virtual limit line having a predetermined width from the outermost obstacle such as a wall recognized by the image analysis unit 220 Or may be preset to recognize.

The image analyzing unit 220 detects an outline or the like in a map image or recognizes an obstacle and a moving path by referring to object information (for example, an outer wall, a window, a doorway, a road, etc.) included in the map information And can be pre-programmed. The method of recognizing the obstacle and the moving path by interpreting the object information by using the image analysis technique is obvious to those skilled in the art, so a detailed description thereof will be omitted.

Since the fire hose can enter the interior of the building using, for example, a window or a doorway, the image analyzing unit 220 can preset the space inside the building connected to the window by the window or the entrance, .

The fire fighting equipment selection unit 230 refers to the analysis information analyzed by the image analysis unit 220 to generate the fire fighting equipment selection information related to the arrangement position of the fire fighting equipment and the characteristic information of the fire fighting compartment to be disposed.

For this purpose, the fire-fighting equipment selection unit 230 forms the inside of the fire-fighting limit 120 as a grid made up of blocks formed of guide lines of a predetermined width, and corresponds to a moving path among blocks constituting the grid Blocks are defined as fire routes. Here, the fire-fighting route may be preset to include a block through which the fire hose extends directly and / or a block from which the fire-fighting water injected from the extended fire hose is reached.

In FIG. 3 (c), two buildings are arranged for convenience of explanation, and a fire-fighting route is defined for a space outside the outer wall of the building. However, the number and shape of the buildings to be disposed may vary, As a matter of course, it is natural that the space inside the building through the window or the entrance can also be considered as a fire route as a moving path.

The length of the fire hose and the water pressure corresponding to one fire fighting box can be determined in advance according to factors such as economic efficiency and field conditions and the number of blocks corresponding to the travel route and / The quantity of the fire fighting box to be provided corresponding to the predetermined condition such as the limitation of the quantity of the maximum block not included in the number of blocks.

As shown in FIG. 3C, when two fire boxes 310 and 320 are installed, the fire block selector 230 selects two blocks spaced apart from the blocks corresponding to the travel path After temporarily designating the corresponding two fireboxes 310 and 320 (i.e., fire hydrants) as reference blocks for installation, the length of the fire hose corresponding to the fire fighting characteristics information in each reference block, The blocks respectively included in the fire fighting paths of the fire fighting boxes 310 and 320 are defined as the fire fighting path limits 315 and 325 in consideration of the fire fighting water reaching distance.

At this time, the fire fighting equipment selection unit 230 repeatedly analyzes the fire fighting path limits 315 and 325 while changing the position of the reference block, and blocks included in the plurality of fire fighting path limits 315 and 325 The reference block (that is, the installation position of the fire-fighting box) can be designated to a position where there is no or a predetermined quantity or less.

In this case, the fire-fighting equipment selection unit 230 may, for example, remove the fire-fighting box corresponding to the fire-fighting path limit if all the blocks have a fire-fighting path limit common to the other fire- There will be.

For example, when some blocks are common to other fire fighting route limits, the fire fighting equipment selection unit 230 may refer to the previously stored fire fighting property information so that a fire fighting hose having a relatively short length is provided in one fire fighting box , A pump having a relatively low water pressure may be selected.

In FIG. 3 (c), two fireboxes 310 and 320 are provided within the fire protection limit 120, and the first firebox 310 includes a block that can reach up to nine hops from the reference block, And the second fire box 320 has a fire path limit defined by blocks that can be reached by a maximum of three hops. However, it goes without saying that the fire path limit of each fire fighting box may be specified to have the same maximum number of hops. Here, it is a matter of course that the maximum number of hops corresponding to each fire fighting box can be determined by the characteristic information of the fire fighting box (that is, the length of the fire hose provided in the fire fighting box and the waterproof pressure).

Also, when the fire-fighting path limit is set so as to exclude blocks less than a predetermined number of blocks existing in the fire-fighting limit 120, the fire-fighting facility selection unit 230 determines that the blocks are relatively long Length fire hose may be provided or a pump having a relatively large water pressure may be selected.

Of course, the fire fighting equipment may be selected in such a manner that a fire extinguisher is disposed corresponding to one or more blocks excluded from the fire path limit. If a fire extinguisher is placed for a plurality of blocks excluded from the fire path limit, the arrangement interval between the fire extinguishers can be specified in advance.

Referring back to FIG. 2, the visualization processing unit 240 uses the fire-fighting facility selection information (i.e., the location of the fire-fighting equipment and the characteristics of the fire-fighting box to be placed) generated by the fire- Generates fire map information in which fire fighting facilities (for example, fire fighting box, fire hydrant, fire extinguisher, etc.) are disposed.

The fire map information may be, for example, a fire map image, in which the fire path limits corresponding to the respective fire fighting facilities arranged are identified to each other.

4 is a flowchart illustrating a method of visualizing a fire area according to an embodiment of the present invention.

Referring to FIG. 4, in step 410, the fire area visualizing system 200 generates or reads out a map image corresponding to the map information of the selected area to perform the fire area visualization, or reads it from the storage unit 210. At this time, the generated map image may be stored in the storage unit 210 and managed.

In step 420, the fire fighting area visualization system 200 sets a fire fighting limit 120 corresponding to the read map image, and recognizes obstacles and travel paths respectively in the map image. For example, in order to recognize an obstacle and a moving route in a map image, for example, an outline or the like is detected in a map image, or object information (for example, an outer wall, a window, a doorway, a road, etc.) Method can be used.

The fire protection limit 120 can be set in advance so as to be recognized as an imaginary limit line having a predetermined width from the outermost obstacle such as the wall recognized in the map image, individually or in advance for each map information of each area.

In addition, since the fire hose can also enter the interior of the building using an opening such as a window or an entrance, the fire-fighting area visualization system 200 is provided with a moving path connected to a space inside the building, Or may be preset to recognize.

In step 430, the fire area visualization system 200 forms a grid of a plurality of blocks inside the fire limit 120, and controls the fire extinguishing facility 120 to form an optimal fire path limit within the fire limit 120, The location, the type and the quantity of the product.

The fire fighting area visualization system 200 forms a fire fighting path so that the blocks corresponding to the moving path in the map image are included in the fire fighting route. At this time, the space inside the building connected by the openings (for example, As shown in Fig.

The fire area visualizing system 200 arranges a fire box by designating any block among the blocks corresponding to the travel path in the map image as a reference block and arranges the fire box in accordance with the length of the fire hose and / Blocks that can be reached within a certain number of hops can be defined as the fire path limit.

At this time, if a plurality of fire fighting chambers are provided in the fire fighting limit 120, at least one of a placement position of the fire fighting box, a length of the fire fighting hose, Can be determined. Also, if there is a block that is not included in all of the plurality of fire path limits, the fire fighting equipment may be determined so as to change the characteristic information of the fire fighting box or place the fire extinguisher at a position corresponding to the block.

If the optimal fire fighting path limit is determined within the fire fighting limit 120, the fire fighting area visualization system 200 generates the fire fighting map information in which the fire fighting facility is disposed and stores it in the storage unit 210 in step 440.

As described above, the fire fighting area visualizing system and method according to the present embodiment are characterized in that an effective fire fighting system can be constructed by selecting an optimal fire fighting facility and a location in consideration of an obstacle.

It is needless to say that the above-described method of visualizing the fire area can be performed by an automated procedure in a time-series sequence by a software program or the like embedded in the digital processing apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable medium, readable and executed by a computer, thereby implementing the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and the like.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
