3, the display module 230 can display the relative position information along the direction and the distance of the marine vessels around the position (center of the circle) of the main line, and the direction and speed of the marine vessel.

In order to distinguish a pirate ship from a general ship, various factors are needed. For this purpose, it is necessary to analyze the characteristics of the pirate ship. In addition, the pirate ship is a boat-shaped small ship and has a common feature of approaching the target ship at high speed.

Therefore, the pirate line setting module 240 according to the embodiment of the present invention sets the width (WIDTH), the speed (SPEED) and the CPA (Closest Point) of a peripheral ship for distinguishing a pirate ship from a general ship, of Approach) to the pirate ship's decision element. Here, the CPA means the shortest approach distance between the main line and the peripheral vessel.

The pirate ship setting module 240 can set a differential risk setting value of each judgment element, set a risk reference value to be compared with a final risk calculated by a combination of the individual risks of the determination factors, and the sensitivity thereof.

Here, the description of the risk setting value, the risk reference value, and the sensitivity of each pirate ship determination element will be described in detail in an embodiment in which the following pirate ship determination module determines the pirate ship.

However, in the embodiment of the present invention to be described later, it is assumed that the speed and CPA of the peripheral ship among the various pirate ship determination factors are explained for convenience of explanation, but the determination factor is not limited thereto.

The pirate ship determining module 250 calculates the speed and the CPA value for each peripheral ship based on the monitoring information of peripheral ships received periodically (for example, every 2.5 seconds) from the monitoring unit 100, .

The storage module 260 stores various setting data and programs for pirate ship determination and records various monitoring information and calculation data collected and generated in accordance with the peripheral ship surveillance in a time series.

The pirate ship determining module 250 automatically calculates the final risk after combining the velocities and CPA values of the stored peripheral vessels, and displays the final risk for each peripheral ship through the UI of the display module 230.

At this time, the pirate ship determining module 250 compares the final risk of each peripheral ship with the risk reference value, and the ship having the final danger level above the reference value can be determined to be a pirate ship and displayed and alarmed.

Meanwhile, FIG. 4 is a graph illustrating a risk calculation method by CPA of a peripheral ship according to an embodiment of the present invention.

5 is a graph illustrating a risk calculation method according to a speed of a peripheral ship according to an embodiment of the present invention.

4 and 5, the risk due to the CPA of the peripheral vessel can be numerically displayed from 0 to 225, and the risk due to the speed can be displayed from 0 to 255, for example, 122 A ship with a risk of 250 means a higher risk than a ship with a risk.

As described above, although there are various factors for calculating the risk to the ship, the present embodiment explains that the pirate ship determination module 250 calculates the risk with the CPA value and speed.

For example, in case of vessel A, since the CPA value is 1.8 (NM) and the speed is 24 (KN), the risk of each judgment element is calculated as follows.

- Ship (A) Information: CPA 1.8 (NM), speed 24 (KN)

- The risk of CPA 1.8 (NM) is 102 (see Figure 4)

- The risk of speed 24 (KN) is 255 (see Figure 5)

The pirate ship determining module 250 calculates the final risk by weighting each of the risk factors of the CPA value and the speed, which are the determination factors. Assuming that the weight value assigned at this time is set to 40% of the CPA and 60% of the speed, The final risk can be calculated as:

- Final risk of vessel (A) = (102 * 0.4) + (255 * 0.6) = 194

Here, the weight is set according to the importance of the determination factor on the determination of the pirate ship, and the pirate ship setting module 240 can set the value input from the user through the UI.

In the case of vessel B, since the CPA value is 0.5 (NM) and the speed is 20 (KN), the risk of each judgment element is calculated as follows.

- Ship (B) Information: CPA 0.5 (NM), speed 20 (KN)

- The risk of CPA 0.5 (NM) is 204 (see Figure 4)

- The risk of speed 20 (KN) is 255 (see Figure 5)

The pirate ship determining module 250 can calculate the final risk of the ship B as follows, assuming that the weight is set to 40% CPA and 60% speed.

- Final risk of ship (B) = (204 * 0.4) + (255 * 0.6) = 235

Here, when comparing only the final risk of the two ships, the ship (A) is 194 and the ship (B) is 235, so that the ship (B) can be regarded as a dangerous ship as compared with the ship (A).

The pirate ship determination module 250 of the integrated management unit 200 compares the final risk of each ship with a preset risk reference value and generates a stepwise alarm by separating the risk level into a differential level as shown in Table 1 below.

<Table 1> Criteria for risk assessment

For example, when the calculated final risk level is 204 or higher, an alarm of a pirate line occurrence alarm level is generated. If the calculated final risk level is 204 or higher, a pirate line alert alarm is generated at a lower middle level, .

That is, in the case of the ship A in the above embodiment, an alarm corresponding to the 'Middle' level is generated because the final risk level is 194, and in the case of the ship B, the final risk level is 235, Alarms can be generated.

As described above, the pirate ship determining module 250 of the integrated management unit 200 automatically calculates the final risk by weighting each risk according to the CPA and the speed of the surrounding vessels, compares the final risk with the risk reference value, Of pirate ships.

The determination of the pirate ship for the peripheral ship of the pirate ship determining module 250 may be performed by using the UI of the pirate ship setting module 240, such as the width of the ship, the CPA, the speed and the weight, Setting.

That is, according to the pirate line setting information of the pirate line setting module 240 according to the user's adjustment (input), the risk calculation and the pirate line determination criteria for the peripheral ships of the pirate ship determining module 250 can be reflected differently.

6 and 7, a description will be given of a method of calculating the risk of peripheral vessels according to the change of the CPA and the speed setting among the pirate ship determination factors.

6 is a graph illustrating a risk level changed according to a CPA setting change according to an embodiment of the present invention.

Referring to FIG. 6, when the pirate line setting module 240 changes the CPA setting value from 3 (NM) to 5 (NM) according to the user's adjustment, the risk of the ship is changed .

For example, assuming the ship A described above with reference to FIG. 4, the risk of each of the determination factors before the change when the CPA value is 1.8 (NM) and the speed is 24 (KN) is calculated as follows.

- Ship (A) Information: CPA 1.8 (NM), speed 24 (KN)

- The risk of CPA 1.8 (NM) is 102 (see the pre-change graph in Figure 4 or Figure 6)

- the risk of speed 24 (KN) is 255 (see Figure 5)

Then, assuming that the weight assigned to each judgment element is set to 40% CPA and 60% speed, the final risk of vessel (A) is automatically calculated as follows.

- Final risk of vessel (A) = (102 * 0.4) + (255 * 0.6) = 194

On the other hand, if the user calculates the risk after changing the setting value of the CAP from the existing 3 (NM) to 5 (NM) in the same vessel (A) information as follows.

- Ship (A) Information: CPA 1.8 (NM), speed 24 (KN)

- The risk of CPA 1.8 (NM) is 153 (see the post-change graph in Figure 6)

- the risk of speed 24 (KN) is 255 (see Figure 5)

Assuming that the weight value assigned to each judgment element is set to 40% CPA and 60% speed, the final risk of the vessel (A) whose CPA setting is changed is automatically calculated as follows.

- Final risk of ship (A) = (153 * 0.4) + (255 * 0.6) = 214

When the user changes the CPA setting value from 3 (NM) to 5 (NM) in the UI screen through the pirate line setting module 240, the pirate ship determining module 250 sets the final risk to a changed value of 194 to 214 .

When the pirate ship line judging module 250 compares the final danger level changed from 194 to 214 with the risk reference value in Table 1, the alarm level is changed from "Middle" to "High".

That is, even if the ship has the same CPA value (for example, 1.8 NM), the risk varies depending on the CPA setting value set by the user through the pirate ship setting module 240.

Next, FIG. 7 is a graph illustrating a risk level changed according to the speed setting change according to the embodiment of the present invention.

Referring to FIG. 7, when the pirate ship setting module 240 changes the speed setting value from 30 (KN) to 10 (KN) according to the user's adjustment, the risk of the ship is changed .

For example, when the CPA value of the ship C is 1.8 (NM) and the speed is 10 (KN), the risk of each decision element before changing the speed set value is calculated as follows.

- Ship (C) Information: CPA 1.8 (NM), speed 10 (KN)

- The risk of CPA 1.8 (NM) is 102 (see Figure 3)

- The risk of speed 10 (KN) is 50 (see the pre-change graph in Figure 7)

And, assuming that the weight given to each judgment element is set to 40% CPA and 60% speed, the final risk of ship C is automatically calculated as follows.

- Final risk of ship C = (102 * 0.4) + (50 * 0.6) = 71

On the other hand, in the same ship (C) information as above, when the user changes the speed setting value from the existing 3 (NM) to 5 (NM), the risk is calculated as follows.

- Ship (C) Information: CPA 1.8 (NM), speed 10 (KN)

- The risk of CPA 1.8 (NM) is 102 (see Figure 4)

- The risk of speed 10 (KN) is 50 (see the graph after the change in Figure 7)

Assuming that the weight value assigned to each judgment element is set to 40% CPA and 60% speed, the final risk of the ship C whose set value is changed is automatically calculated as follows.

- Final risk of ship C = (102 * 0.4) + (255 * 0.6) = 194

When the user changes the setting value of the speed from 30 (KN) to 10 (KN) on the UI screen through the pirate line setting module 240, the pirate ship determining module 250 changes the final risk from the changed value of 74 to 194 .

Then, the pirate ship determining module 250 changes from the normal "safe" state to the "middle" level alarm by comparing the final risk changed from 74 to 194 with the risk reference value of Table 1 above.

That is, even if the ship has the same speed (for example, 10 KN), the danger level varies depending on the speed set value set by the user through the pirate ship setting module 240.

Meanwhile, the pirate line setting module 240 according to the exemplary embodiment of the present invention sets the sensitivity level of the risk reference value as LOW, MID, and HIGH according to UI adjustment of the user as shown in FIG. It can be set to either one.

This allows the user to easily adjust (change) the sensitivity for pirate ship determination through the UI by setting the risk reference value, which is a comparison criterion of the final risk of the surrounding vessels, to a plurality of setting values differently according to the boundary water level.

For example, the pirate ship determination module 250 determines the risk of nearby ships with the risk standard value shown in <Table 2> below when the user selects the sensitivity of the risk reference value as the normal (MID).

For example, the pirate ship determination module 250 generates a pirate ship boundary alert at the 'Middle' level when the final risk of the calculated ship is 170.

<Table 2> Criteria for risk assessment (MID)

Meanwhile, when the user selects the sensitivity of the risk reference value as HIGH, the pirate ship determination module 250 changes the risk determination criteria as shown in Table 2 below.

At this time, when the final risk level of the ship calculated as above is 170, the pirate ship determining module 250 may issue a 'High' level pirate ship occurrence alarm.

<Table 3> Criteria for risk assessment (HIGH)

Thus, by setting the sensitivity level of the danger reference value higher, it is possible to selectively adjust the alarm level according to the surrounding environment by generating a higher level danger alarm even for the same danger ship.

In other words, it is possible to easily control the monitoring and warning level by selectively setting the sensitivity set in plural, such as when the ship is habitually navigating to a dangerous area where a pirate ship appears, or when the visibility is poor due to nighttime or mist.

The counterpart 300 includes a water cannon 310, a water shutter 320, and a remote controller 330 that are remotely operable as equipment for obstructing the boarding of pirates when the pirate ship approaches within a certain distance from the main line.

The water cannon 310 includes driving means for changing the water nozzle for emitting the water cannon in the up, down, left, and right directions, and fires the water cannon toward the pirate ship in accordance with a control signal applied from the integrated management unit 200.

The water shutter 320 blows hot water to the outside of the hull of the main line according to an applied control signal to prevent the pirates from climbing to the main line.

The remote controller 330 is connected to corresponding devices such as the water cannon 310 and the water shutters 320 in a wired or wireless communication and drives the corresponding devices using a control module such as a joystick in a relatively safe place such as a wheelhouse Can be controlled.

A method of controlling a pirate ship setting system according to an embodiment of the present invention will be described with reference to FIG.

FIG. 8 is a flowchart illustrating a method for a pirate ship fighting system according to an embodiment of the present invention.

Referring to FIG. 8, when the pirate ship surveillance is started (S110), the integrated management unit 200 according to the embodiment of the present invention sets a pirate ship line for determining a pirate ship among peripheral ships existing in a predetermined area around the main ship (S120).

If the CPA change value is inputted from the user through the UI for setting the pirate ship line (S121; Yes), the integrated management unit 200 changes the CPA setting value for risk calculation (S124).

If the speed change value is input from the user through the UI for pirate line setting (S122; YES), the integrated management unit 200 changes the speed setting value for risk calculation (S124).

If the sensitivity change of the risk reference value is input from the user through the UI for setting the pirate ship line (S123; Yes), the integrated management unit 200 changes the sensitivity setting for risk calculation (S124).

The pirate line setting function adjustment step (S120) is performed only when there is input change of the user through the UI, and may be omitted at normal times. Also, although not shown in the drawing, in the step of adjusting the pirate ship setting function (S120), the weight ratio according to the importance of each determination element may be changed.

The integrated management unit 200 collects monitoring information such as the position, the inflow, and the speed of the main and peripheral vessels from the monitoring unit 100 in step S130, and calculates and stores the velocity and the CPA value of the peripheral vessels in step S140.

Then, the integrated management unit 200 calculates the risk of each of the surrounding vessels by the determination factors (S150). That is, each individual risk is calculated by comparing the speed and CAP value of the surrounding vessel with each setting value reflected through the pirate ship setting function.

In step S160, the integrated management unit 200 calculates the final risk of the peripheral vessel by assigning weights according to the importance of the determination factors to the individual risks, and adding the weighted individual risks.

The integrated management unit 200 compares the final risk of the peripheral vessel with the risk reference value for determining the pirate ship line in step S170 and if the final risk is equal to or greater than the risk reference value in step S180, Occurrence alarm and response are performed (S190).

For example, the integrated management unit 200 may transmit a danger ship occurrence signal (pirate ship occurrence signal) to the ship alert module 170, and may transmit the pirate ship occurrence alert to the land and other ships to inform or request assistance.

At this time, the danger ship warning alerting can be alerted to one of the level of the pirate line generation alarm (High), the pirate line boundary warning (Middle) and the pirate line caution alarm (Low) according to the sensitivity of the danger standard and its setting value.

In addition, the water cannon 310 and the water shutter 320 can be driven through the remote controller 330 in cooperation with the counterpart 300 so as to counter the access of the pirate ship.

On the other hand, if it is determined in step S180 that the final risk is less than the established risk reference value (S180: NO), the process returns to step S130 and repeats the dangerous vessel monitoring according to the peripheral vessel monitoring information collection.

As described above, according to the embodiment of the present invention, it is possible to warn occurrence of dangerous vessels early by setting various judgment factors for characteristic determination of a pirate ship, comparing it with the monitoring information of nearby ships, and calculating the risk thereof .

Also, it is possible to easily set the sensitivity level of the risk reference value for the setting of the pirate ship determination element and the pirate ship determination through the user interface (UI), and thus the level of the pirate ship boundary according to the surrounding environment can be simply controlled.

In addition, there is an effect that the discrimination power of the pirate ship can be enhanced by calculating and calculating the final risk by setting and reflecting the weights of the various pirate ship determination factors according to their importance.
