Best Mode for Carrying Out the Invention Hereinafter, a configuration and an operation of a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram of an intelligent fire fighting system according to an embodiment of the present invention. The intelligent fire fighting system includes a thermal image camera 10, a first sprinkler 20, and a first control center server 30.

It is also preferable that a plurality of second sprinklers 40 are further included in the thermal imaging camera 10, the first sprinkler 20, and the first center server 30.

More specifically, when the thermal image camera 10 collects thermal images of a predetermined temperature value or more for fire judgment in the course of photographing according to a plurality of first coordinate values with respect to an arbitrary space, Value.

For example, FIG. 2 (a) illustrates an arbitrary space and FIG. 2 (b) illustrates a plurality of first coordinate values for a partial region of FIG. 2 (a) A, B, C, D, E, and F are photographed.

In this case, since the thermal camera 10 can determine whether a fire is present through a thermal image to be photographed, a temperature value that can be determined as a fire in the thermal image collection is set, and a second coordinate Value.

For example, if a fire occurs in the area C shown in FIGS. 2 (a) and 2 (b), the coordinate value of the area C, that is, the second coordinate value, is used for the C zone fire suppression by using the first sprinkler 20. The thermal imaging camera 10 sequentially photographs a plurality of first coordinate values to generate a second coordinate value.

As a result, the second coordinate value is a region in which the first sprinkler 20 is sprinkled because it is a region where a fire occurs.

The thermal image camera 10, like a PTZ (Pan Tilt Zoom) network camera, moves up and down and simultaneously rotates 360 degrees (having a vertical angle and a horizontal rotation angle). At this time, This is a possible area and it is to monitor these areas with thermal images.

The first sprinkler 20 changes direction toward the received second coordinate value upon receipt of the second coordinate value to fire fire extinguishing materials for fire fighting.

That is, the first sprinkler 20 collects the thermal image of the temperature value set by the thermal imaging camera 10, that is, the fire has occurred, and the area where the fire occurs corresponds to the second coordinate value, The coordinate values are generated in the thermal imaging camera 10 and transmitted to the first control center server 30, and are received a second coordinate value through the first control center server 30.

Accordingly, the first sprinkler 20 is operated in response to the second coordinate value being turned toward the second coordinate value and receiving the first sprinkler control signal from the first control center server 30.

The first sprinkler 20 is provided with a firefighter window and the firefighter window is controlled by a first firefighter window control signal included in a first sprinkler control signal transmitted from the first control center server 30, 1 Fireman's window control signals are described in detail below.

Particularly, it is preferable that the thermal camera 10 and the first sprinkler 20 are formed as a pair.

For example, as shown in FIG. 3, if there is a building having spaces A, B, C, and D, and a fire occurs in a part of the space B, a sprinkler constructed in spaces A, It is preferable that the thermal camera 10 and the first sprinkler 20 are formed as a pair so as to suppress the fire generated in the space.

It is also preferable that one thermal camera 10 and at least one first sprinkler 20 are formed as a pair.

For example, if there are one thermal camera 10 and two first sprinklers 20, the second coordinate values generated by the thermal camera 10 may be respectively set up as the two first sprinklers 20 receive Position to the second coordinate value, and each of the two first sprinklers 20 sprays water.

The first control center server 30 has a first application in which the arbitrary space has a plurality of first coordinate values and instructs the thermal imaging camera 10 to shoot in accordance with a plurality of first coordinate values, Receives a second coordinate value from the camera 10 and provides it to the first sprinkler 20 and generates and transmits a first sprinkler control signal for sprinkling fire extinguishing material to the first sprinkler 20.

That is, the first control center server 30 has a plurality of first coordinate values for an entire arbitrary space in order to extinguish only the specific region when a fire occurs in a specific region in an arbitrary space for the purpose of the present invention And a first application for instructing the thermal imaging camera 10 to be photographed in accordance with a plurality of first coordinate values.

Accordingly, the first control center server 30 communicates with the thermal imaging camera 10 so that the thermal imaging camera 10 is photographed by the first application in accordance with a plurality of sequential first coordinate values, Communication is established with the first sprinkler 20 to be redirected to the second coordinate value by the first application.

At this time, the reason why the first coordinate values are constructed is that the thermal imaging camera 10 does not photograph the arbitrary space only once, and continuously shoots whether a fire has occurred, so that the fire can be monitored with a regular trajectory .

Next, the first control center server 30 transmits a second coordinate value and a first sprinkler control signal to the first sprinkler 20. The second coordinate value is first received from the thermal camera 10, To the sprinkler (20), and the first sprinkler control signal is transmitted so that the first sprinkler (20) can fire the extinguishing material for fire suppression.

In particular, the first sprinkler control signal is further provided to the first sprinkler 20 to control a firefighter window to control the spraying range.

That is, the first sprinkler 20 is provided with a firefighter window for spraying the firefighting fire extinguishing material with a wider water spraying range or a narrower water spraying range. At this time, the firefighter window receives the first firefighter window control signal So that the spraying range can be adjusted by being included in the first sprinkler control signal and transmitted to the first sprinkler 20.

For example, referring to FIG. 4, the area A shown in FIG. 4 is a region in which a fire occurs, and the fire is suppressed by the first sprinkler 20. However, when a fire occurs, A plurality of second sprinklers 40 are further included in the areas A, B, C, D, E and F in the vicinity of the area A shown in FIG. 4 in order to fire fire fighting fire extinguishers.

Meanwhile, the plurality of second sprinklers 40 may be provided with a unique code for identifying each of the second sprinklers 40, and the second sprinkler control signals may be provided individually or in groups to fire extinguishing materials for fire suppression.

For example, if a conventional sprinkler sprinkles a fire extinguisher in the entire space shown in FIG. 4, a phenomenon similar to that of the conventional art described above occurs, so that the plurality of second sprinklers 40 is provided with a unique cord As shown in FIG. 4, when the first sprinkler control server 30 selectively transmits the second sprinkler control signal, only the areas A, B, C, D, E, and F shown in FIG. So that a plurality of second sprinklers 40 are operated individually or in groups.

In this way, in order to transmit the second sprinkler control signal individually or in groups, the first control center server 30 has received the second coordinate value, which means that a fire has occurred at the second coordinate value There may be an element around the second coordinate value that may cause the fire to recur or enlarge, so that for each of the plurality of second sprinklers (40) having the unique code for fire suppression for the area around the second coordinate value It is preferable to include position information.

Meanwhile, the first control center server 30 transmits the second coordinate value and the column image of the second coordinate value by the number of times set to the manager portable terminal before transmitting the first sprinkler control signal.

For example, if the fire rating is high, the first sprinkler server 30 can fire without any condition, but if the fire rating is low, A person ignites a lighter, and the like, is not a fire event. Therefore, a thermal image of a second coordinate value and a second coordinate value is transmitted a predetermined number of times to confirm such a case.

The manager portable terminal transmits a control signal for controlling the thermal camera 10 and the first sprinkler 20 to the first center server 30 so that the thermal camera 10 and the first sprinkler 20 ) Is more preferably controlled.

For example, the manager portable terminal has a configuration in which software and hardware are combined to control the thermal camera 10 and the first sprinkler 20 by using communication between the first control center server 30 When the manager portable terminal transmits a control signal for controlling the thermal camera 10 and the first sprinkler 20 to the first control center server 30, the first control center server 30 transmits a control signal to the thermal camera (10) and the first sprinkler (20).

Accordingly, the manager portable terminal not only monitors the fire area through the control of the thermal camera 10, but also controls the sprinkling range and direction with respect to the fire area through the control of the first sprinkler 20.

In this way, the manager portable terminal controls the thermal camera 10 and the first sprinkler 20 to perform an initial fire suppression for a fire area in which fire-fighting personnel can not directly enter in order to suppress a fire .
