The mist spraying unit 140 injects the water mist into the target area under the control of the control unit 210. [

The mist spraying unit 140 is provided, for example, in a storage tank for storing the water to be sprayed, a pump for allowing the water stored in the storage tank to be conveyed through the water conveyance pipe at a predetermined pressure, And a spray nozzle for spraying the water transferred in the form of a mist. The control unit 210 may control the operation of the pump and / or the valve to control the water mist injection of the mist ejection unit 140. The control unit 210 controls the operation of the pump and / You can do it.

The control unit 210 refers to the radiant heat measurement value information received from the radiant heat measuring units 130 provided for each target area and the motion related information provided from the motion sensing unit 135 installed for each target area, If it is determined that a safe operation for the target area is required after the determination of whether or not the boat is present in the area, the start of driving of the mist injection unit 140 is controlled. The mist spraying control by the control unit 210 will be described later in detail with reference to Figs. 3 and 4. Fig.

3 and 4 are flowcharts illustrating a method of controlling a water mist injection according to an embodiment of the present invention.

Referring to FIG. 3, in step 310, the control unit 210 receives radiation heat measurement value information from each radiation heat measurement unit 130 installed in the hull 100. As described above, each of the radiant heat measuring units 130 can be installed separately for each target area.

In step 320, the control unit 210 determines whether there is radiant heat measurement value information exceeding a predetermined limit value using the received radiant heat measurement value information. Here, the limit value may be specified in advance as an empirical, statistical radiant heat measurement value for the safety of the shipowner located in the target area.

As a result of the determination in step 320, if there is no radiant heat measurement value information exceeding the predetermined limit value, the process proceeds to step 310 again.

As a result of the determination in step 320, if there is radiant heat measurement value information exceeding the predetermined limit value, in step 330, the control unit 210 calculates the radiant heat measurement value corresponding to the radiant heat measurement unit 130 that transmitted the corresponding radiant heat measurement value information It is determined whether or not the ship's boat is located within the danger zone, which is the target area.

At this time, the control unit 210 uses the motion-related information received from the motion detection unit 135, which has been allocated the target area corresponding to the radiation heat measurement unit 130 that has transmitted the corresponding radiation heat measurement value information, Can be determined.

As a result of the determination in step 330, if there is a boarding source located within the danger area, the control unit 210 proceeds to step 340 and causes the mist injection unit 140 to start spraying the mist spray unit 140 And outputs a control command.

The radiant heat in the corresponding dangerous area will be relatively reduced by the water mist spraying process, and while the water mist spraying process is being performed, the control unit 210 refers again to the radiant heat measurement value information received for the dangerous area, The injection pressure may also be adjusted.

In step 340, the control unit 210 refers to the motion-related information provided from the motion-sensing unit 135 to recognize the moving direction of the boarding source in the dangerous area.

For example, if the motion-related information provided by the motion-sensing unit 135 includes motion-sensing information that is sequentially generated by a plurality of motion-detection sensors, the control unit 210 may use the order relationship between the motion- The direction of movement will be recognized.

As another example, if the motion-related information provided by the motion detection unit 135 is a camera image photographed with respect to a target area, the control unit 210 controls the video image processing for each frame of the camera image, The direction of movement will be recognized.

If it is determined in step 350 that the target area to be moved is a danger zone by the movement direction of the recognized boarding source, the control unit 210 determines whether or not the mistake for the danger zone to be moved And controls the start of injection.

As a result of the determination in step 330, if there is no aboard source located in the corresponding hazard area, the control unit 210 proceeds to step 410 and determines whether the aboard source exists in the surrounding area, .

If there is no boarding source in the surrounding area, the process proceeds to step 310.

However, if a boarding source exists in the peripheral area, the control unit 210 recognizes the moving direction of the boarding source in the peripheral area using the motion-related information received about the peripheral area in step 420. [

In step 430, the control unit 210 determines whether or not the direction of movement of the recognized boarding member approaches the dangerous area recognized by the determination of step 320 to step 330. [

If the victim is not approaching the hazardous area, proceed to step 310.

However, if the corresponding shipper approaches the danger zone, the control unit 210 controls to start the mist injection for the danger zone to be moved even if no shipboard is currently present in the danger zone to be moved do.
