1, the pirate ship access prevention system includes a pirate ship monitoring unit 110, a display unit 120, an input unit 130, an air supply unit 140, a plurality of nozzle units 150_1, 150_2, ..., 150_n, (Hereinafter, referred to as " 150 " when no division of the nozzle unit is required) and a control unit 160. [

The pirate ship surveillance unit 110 detects whether or not a pirate ship exists around a protected ship (i.e., a ship the pirate ship approaches for the purpose of piracy or the like), information on the existence direction and distance of the pirate ship based on the protection ship, if any Lt; / RTI >

The pirate ship monitoring unit 110 may be, for example, a radar device that detects a target using reflection of a radio wave and measures its position, a CCTV that provides a situation around the protection ship as video information, And a distance sensor module for measuring the time taken to receive the reflected wave from the distance sensor module and calculating the distance. It is natural that the device can be included in the pirate ship monitoring unit 110 without any limitations as long as it can be used to calculate the direction and distance of the pirate ship.

The display unit 120 displays the pirate ship information provided from the pirate ship line monitoring unit 110 (for example, one or more of the direction of the pirate ship and / or information on the distance from the protective ship, ) Information.

Further, the display unit 120 may further display an operation screen for inputting a user operation command for the derived pirate information. Here, the user operation command includes, for example, a target area selection command for specifying the location of the pirate ship and controlling the nozzle unit 150 to be driven (refer to FIG. 4), a distance corresponding to the separation distance from the pirate ship A bubble generation command, a bubble generation command, and an injection command for causing air to be generated at a corresponding position by a spraying force for generating a bubble.

The input unit 130 includes at least one operation button, and the user can input a predetermined user operation command using the operation button provided.

For example, when the display unit 120 is implemented as a touch sensitive screen, the display unit 120 and the input unit 130 may be integrated. Of course, when an additional mechanical button is required in addition to a manipulation button in the form of a virtual button on the touch sensitive screen, it is needless to say that the input unit 130 including one or more mechanical buttons may be separately provided.

Also, the input unit 130 may include an operation button for selecting an operation mode of the pirate ship approach prevention system as an automatic operation mode or a manual operation mode.

When the pirate ship approach prevention system operates in the manual operation mode, the air supply unit 140 and the nozzle unit 150 will be driven according to a user operation command inputted through the input unit 130. [

However, in the case where the pirate ship approach prevention system operates in the automatic operation mode, if the presence of another ship is recognized around the protection ship by the pirate ship monitoring unit 110, the controller 160 can detect the direction of another ship, It is possible to detect the distance to the protective vessel and to process the generated bubbles corresponding to the sensed direction and distance.

The air supply unit 140 supplies air to the nozzle unit 150 so that air can be blown at a predetermined pressure corresponding to a distance at which the bubbles are to be formed and the bubbles can be discharged.

2 showing the configuration of the air supply unit 140, the air supply unit 140 includes a plurality of remote valves 210_1, 210_2, 210_3, 210_4 and 210_5, a plurality of air compressors 220_1 And 220_2, and an air tank 230. As shown in FIG. The open / close of each of the remote valves 210_1, 210_2, 210_3, 210_4 and 210_5 can be remotely controlled by the control unit 160. [

Also, the air supply unit 140 has two paths for supplying air to the nozzle unit 150 at different jetting powers, and the two paths can be operated to have a mutually exclusive relationship in which only one is selectively used.

The first path includes a first remote valve 210_1, a first air compressor 220_1 for providing air at a constant pressure, a second remote valve 210_2, an air tank 230 and a third remote valve 210_3 . Here, the second remote valve 210_2 and the third remote valve 210_3 also function to control the pipeline so that the air pressure in the air tank 230 is maintained.

The second path includes a fourth remote valve 210_4, a second air compressor 220_2 and a fifth remote valve 210_5 for providing air at a pressure controlled by the controller 160.

When the first remote valve 210_1, the second remote valve 210_2 and the third remote valve 210_3 are opened and the fourth remote valve 210_4 and the fifth remote valve 210_5 are closed, Is supplied through the first path and the high pressure air supplied by the first air compressor 220_1 is buffered in the air tank 230 and then supplied to the nozzle unit 150. [ Therefore, in this case, air bubbles may be generated at a certain distance from the protective vessel.

Conversely, when the fourth remote valve 210_4 and the fifth remote valve 210_5 are opened and the first remote valve 210_1, the second remote valve 210_2 and the third remote valve 210_3 are closed, The air supplied to the first air compressor 150 is supplied through the second path and the second air compressor 220_2 supplies the pressure indicated by the controller 160 And supplies the air to the nozzle unit 150. [

2 showing the configuration of the nozzle unit 150, each of the nozzle units 150 includes a remote valve 250 and a nozzle 255 that are remotely controlled by the controller 160 Lt; / RTI >

The nozzle 255 is disposed along the side of the vessel below the water line as illustrated in FIG.

All the nozzles 255 perform the same processing at the same time in generating air bubbles at a predetermined distance from the protection vessel or at a distance specified by the control of the controller 160 by injecting air through the nozzles 255 under the waterline However, if necessary, only the nozzles 255 designated to be in the predetermined area may perform the limited processing (see FIG. 4). That is, only the nozzles 255 that are responsible for the area where the pirate ship is located can be limited to perform the bubble generating process, and the nozzle unit 150 for performing the bubble generating process is controlled by the remote valve 250 ) Can be determined by an open / close operation.

By selectively controlling the nozzle unit 150 to perform the bubble generating process, it is possible to prevent damage to other ships other than pirate ships located around the protection ship.

By adjusting the pressure of the second air compressor 220_2, it is possible to vary the bubble generating distance by the nozzle unit 150, so that the countermeasures can be positively counteracted before the pirate ship approaches the protective vessel, If another approaching ship is being driven by a pirate ship, bubbles may be generated between the other ship and the pirate ship, so that only effective countermeasures against the pirate ship may be possible without harming other ships.

As shown in FIG. 5, a floating object on the sea uses buoyancy, which is the force that the sea water pushes, and buoyancy is proportional to the weight of the hull. Therefore, a large buoyancy force is applied to a large-sized ship compared with a small-sized ship or a boat.

However, in the case of an object floating by the buoyancy force, it may be very dangerous when the buoyancy is reduced at the sea. Among the factors causing the buoyancy reduction, the cause of the bubble is the greatest. This is because, when a large number of bubbles are generated at a position where water should be present, the air inside the bubbles has a repulsive force smaller than that of water. For example, air bubbles generated from submarine volcanoes can affect the buoyancy of a large-sized ship in operation, causing many problems.

Such reduction in buoyancy caused by bubbles may lead to more serious consequences in the case of small vessels or boats than in large vessels. Considering that most pirate ships have the form of small vessels or boats, the pirate ship according to this embodiment Access control systems can anticipate very effective results.

Referring again to FIG. 1, the control unit 160 controls the functions of the illustrated components.

In addition, when the pirate ship approach prevention system operates in the automatic operation mode, the control unit 160 detects the position (i.e., distance and direction) of the pirate ship using the surveillance information provided from the pirate ship surveillance unit 110, The operation of the air supply unit 140 and the nozzle unit 150 can be controlled so that the bubble generating process is performed.

6 is a flowchart illustrating a pirate ship approach prevention method according to an embodiment of the present invention.

Referring to FIG. 6, the controller 160 collects information related to the pirate ship from the pirate ship watch unit 110 in step 610. For example, the information related to the pirate ship to be collected may be at least one of location information (e.g., distance and direction information) of the pirate ship analyzed by the radar device, video information about the pirate ship, and distance information to the pirate ship.

In step 620, the controller 160 determines whether the current operation mode is the automatic operation mode.

If the current operation mode is the automatic operation mode, the controller 160 proceeds to step 630 and uses the collected pirate line related information to generate an operation command corresponding to the position information of the pirate ship (i.e., distance and direction information) .

However, if the current operation mode is the manual operation mode, the controller 160 proceeds to step 640 to receive a user operation command through the input unit 130. [ Here, the user operation command includes, for example, a target area selection command for specifying the location of the pirate ship and controlling the nozzle unit 150 to be driven (refer to FIG. 4), a distance corresponding to the separation distance from the pirate ship A bubble generation command, a bubble generation command, and an injection command for causing air to be generated at a corresponding position by a spraying force for generating a bubble.

In step 650, the controller 160 controls the air supply unit 140 and the nozzle unit (not shown) to generate bubbles below the sea level in the direction and distance corresponding to the operation command generated in step 630 or the user operation command received in step 640 150).

It is a matter of course that the above-described pirate ship approach prevention method may be performed by an automated procedure in a time-series sequence by a built-in program or the like installed 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 by the digital processing apparatus, and is read and executed by the digital processing apparatus to implement the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

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.
