By improving the problem that it is difficult to accurately detect the point P, it is possible to detect the ignition point P relatively accurately and to evolve early.

In other words, by the extinguishing unit 200, since the smoke generated from the flame is high temperature, it is difficult to detect the ignition point (P) using a thermal image, or a real image photographing a visible ray region by smoke The problem of blocking the image is improved to enable relatively accurate detection of the firing point (P).

In this way, the camera member 110 can detect the ignition point P by photographing a thermal image by the thermal image sensor 111, where a pair of the thermal image sensor 111 is provided to be spaced apart from each other. It becomes.

Here, when the thermal image sensors 111 are provided as a pair and are provided to be spaced apart from each other, it is possible to obtain not only two-dimensional firing point P data but also three-dimensional firing point P data.

In other words, the coordinates of each two-dimensional firing point (P) observed by a pair of thermal image sensors 111 spaced apart from each other are different, which means that the firing point (P) is a point located in a three-dimensional area, but the thermal image This is because the sensor 111 photographs two-dimensional coordinates.

According to the extinguisher body 210 as described above, since the area in which the injection unit 220 injects the extinguishing material can be expanded, the ignition point P by detecting the fire can be expanded. You will be able to.

In other words, if the injection unit 220 is configured to evolve the ignition point P in a fixed state, since only the fixed area evolves, there is a limitation in that the evolution area is relatively reduced. The evolution unit 200 of the present invention ) Is configured to further include the extinguisher body 210 to adjust the injection direction of the injection unit 220 so that the extinguishing area for the evolution of the ignition point P can be expanded.

6 is a flow chart showing the automatic fire extinguishing method of the present invention, FIG. 7 is a photograph showing the data processing process of the sensing step in the automatic fire extinguishing method of the present invention, and FIG. 8 is a three-dimensional coordinate derivation step in the automatic fire extinguishing method of the present invention It is a diagram for explaining the derivation of data.

Referring to the drawings, in the automatic fire extinguishing method according to another embodiment of the present invention, by acquiring at least one of thermal image data and real image data taken of an image in a visible light range, a point of an area formed by a flame is determined. It includes a sensing step of selecting an ignition point (P) to acquire the ignition point (P) data, and an evolution step of spraying an extinguishing material to the ignition point (P) according to the ignition point (P) data collected in the sensing step. I can.

As described above, in the automatic extinguishing method of the present invention, the ignition point P is selected as a point such as the center and the lower part of the flame-forming region in the sensing step, so that the ignition point P is quickly determined and data is obtained. . In addition, by extinguishing the ignition point (P) in the extinguishing step after the selection of the ignition point (P), it is possible to quickly select the ignition point (P) at the beginning of the fire and perform its extinguishing.

Here, the sensing step is a specific step for selecting the firing point P, and may include a photographing step, a drawing step, a binding step, a two-dimensional coordinate selection step, and the like.

That is, in the detection step of the automatic fire extinguishing method according to another embodiment of the present invention, the thermal image data and the real image data are performed by the camera member 110 provided with the thermal image sensor 111 and the real image sensor 113. The photographing step of collecting at least one of, a drawing step of drawing an outline (S) of a flame from the thermal image data or the real image data collected in the photographing step, and the outline of the flame (S) derived in the drawing step It may include a binding step of drawing a binding area (B) of an adjacent rectangle, and a two-dimensional coordinate selection step of selecting the coordinates of the center point of the binding area (B) derived in the binding step as the two-dimensional firing point (P).

Here, the photographing step is a step of collecting at least one of the thermal image data by the thermal image sensor 111 and the real image data by the real image sensor 113, as shown in (a) of FIG. This is the step of collecting real image data.

The drawing step is a step of deriving the outline (S) of the flame from the data collected in the photographing step. For example, the outline (S) of the flame is separated and derived as shown in FIG. 7B.

To this end, in the drawing step, the thermal image data or the real image data is converted to a color that makes it easy to distinguish the outline (S) of the flame, and the outline (S) of the flame is converted into a binary such as black and white. By deriving, it may be performed to reduce the error.

The binding step is a step of setting a prerequisite for selecting an ignition point (P), and is a step of deriving a rectangular binding region (B) in which the outline S of the flame derived in the drawing step is inscribed. For example, a rectangular binding area B in which the outline S of the flame is inscribed as shown in FIG. 7C is derived.

The two-dimensional coordinate selection step is a step of selecting a final firing point P from the thermal image data or real image data captured by each thermal image sensor 111 or the real image sensor 113. To this end, in the two-dimensional coordinate selection step, the coordinates of the center point of the binding area B derived in the binding step are selected as the firing point P. For example, the coordinates of the center point of the rectangular binding area B where the outline S of the flame is inscribed as shown in (d) of FIG. 7 is derived as the two-dimensional ignition point P.

In addition, in the detection step of the automatic fire extinguishing method according to another embodiment of the present invention, a two-dimensional firing point (P) in each of the image data captured by the thermal image sensor 111 or the real image sensor 113 disposed at a plurality of positions. ) When the coordinates are derived, the three-dimensional firing point (P) is derived by the proportional value of the difference in the position of the thermal image sensor 111 or the real image sensor 113 from which the image data was acquired and the coordinate value of the two-dimensional firing point (P). It may include a step of deriving three-dimensional coordinates.

That is, when the thermal image sensor 111 or the real image sensor 113 are provided as a pair and are provided spaced apart from each other, as well as the two-dimensional firing point (P) data, as well as the three-dimensional firing point (P) data can be obtained. You will be able to.

In other words, the coordinates of each two-dimensional firing point P observed by a pair of thermal image sensors 111 or 113 spaced apart from each other are different, which means that the firing point P is in a three-dimensional area. This is because the location or the thermal image sensor 111 captures two-dimensional coordinates.

However, according to the pair of thermal image sensors 111 spaced apart from each other, the three-dimensional coordinates of the firing point P can be obtained by a proportional value according to the spaced distance.

That is, the three-dimensional firing point P is derived by a proportional value of the difference in the position of the thermal image sensor 111 or the real image sensor 113 from which the image data is obtained and the coordinate value of the two-dimensional firing point P.

As an example, as shown in FIG. 8, when the distance between the pair of thermal image sensors 111 spaced apart from each other is selected, and the position (Ol) of the left thermal image sensor 111a is selected as a reference point, the right thermal image As for the position (Or) of the sensor 111b, the x-axis coordinate is d. In addition, the distance between the thermal image sensor 111 and the image plane formed by the firing point P is defined as f.

In addition, Pl = (xl, yl), which is the two-dimensional coordinate of the firing point (P) derived from the left thermal image sensor 111a, and Pr, which is the two-dimensional coordinate of the firing point (P) derived from the right thermal image sensor (111b). Assuming that =(xr, yr), and derive P(X, Y, Z), the three-dimensional coordinates of the firing point (P), it becomes as follows.

In addition, assuming that the plane formed by the three-dimensional firing point P and the pair of thermal image sensors 111 is the xz plane, the three-dimensional and two-dimensional coordinates of the firing point P in the z-axis and the x-axis, and each Considering the distance proportional relationship of the thermal image sensor 111, the following equations 1 and 2 are derived.

[Equation 1]

Z/f = X/xl

[Equation 2]

Z/f = (X-d)/xr

In addition, considering the three-dimensional coordinates and two-dimensional coordinates of the firing point P in the z-axis and y-axis, and the distance proportional relationship of each thermal image sensor 111, Equation 3 below is derived.

[Equation 3]

Z/f = Y/yl= Y/yr

That is, since the plane formed by the three-dimensional firing point (P) and the pair of thermal image sensors 111 is assumed to be the xz plane, Y of the coordinates of the two-dimensional firing point (P) derived from the pair of thermal image sensors 111 The values are the same.

Here, since there are three equations and three unknowns are X, Y, and Z, the three equations are combined to obtain the solution of P(X, Y, Z), which is the three-dimensional coordinate of the firing point (P) as follows. I can.

[Equation 4]

X = (xl × d)/(xl-xr)

[Equation 5]

Y = (yl × d)/(xl-xr)

[Equation 6]

Z = (f × d)/(xl-xr)

Further, the sensing step of the automatic fire extinguishing method according to another embodiment of the present invention may include a noise removing step of sucking smoke generated in the data collection area of the sensing step.

That is, when photographing the ignition point (P) in the photographing step, it is difficult to accurately check the thermal image data or real image data due to high-temperature smoke as well as the flame generated at the ignition point (P). In order to collect the image data of (P) relatively accurately, the noise removal step is performed.

That is, when collecting thermal image data and real image data in the photographing step, it is determined whether flame can be observed, and if it is difficult to observe a thermal image or real image of the flame, it is determined whether smoke is observed, and if smoke is observed, the noise By performing the removal step, the smoke is sucked to remove the noise of the collection of thermal image data and real image data.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and various modifications and variations are possible without departing from the technical spirit of the present invention described in the claims. It will be obvious to those of ordinary knowledge.
