Description

Device and method for transmitting video data regarding ship in dangerous situation

The present invention relates to an apparatus and method for transmitting ship image data in a dangerous situation.

In modern society, ships are used for various purposes such as travel, cargo transportation, and national defense, and ships sailing long distances such as large merchant ships or cargo ships may be exposed to pirate attacks on the high seas.

Indeed, recent pirates have been increasingly injured by vessels navigating the Indian Ocean, and the International Maritime Bureau (IMB) is advising to ship vessels for protection from pirates.

Therefore, in areas where damage is expected, unidentified small ships approaching the vessel are alerted by radar or related vessels, and when small ships are identified as pirate ships, they are self-defensive to prevent access by radiating water cannons using fire hoses. In addition, in a situation where the pirate ship is in close proximity to the ship's outer wall using a water curtain or barbed wire, a method of preventing pirates from coming up to the ship is used.

However, it is not easy to identify intelligent pirate ships among surrounding vessels, and there are cases of damages that allow pirates to board ships because they can not grasp pirate ships approaching the main line in advance.

For example, Korean Patent Laid-Open No. 2011-0092555 (Patent Document 1) discloses a pirate intrusion prevention apparatus and method. However, the patent application is about how to warn an unidentified ship that is approaching a certain distance, rather than the actual judgment of whether it is a pirate ship, and because the result of the pirate ship's judgment is not reliable, it hinders sailing or reduces tension of crew. Can cause problems.

The external connection module 210 may collect, for example, monitoring information such as the position, course, and speed of the main ship and surrounding ships from the monitoring unit 110, an alarm signal according to the occurrence of a pirate ship, and a signal for controlling each module. You can also pass

The display module 220 displays the position and movement information of the main ship collected from the monitoring unit 110 and the position and movement information of nearby vessels, and provides a user interface (UI) for setting a pirate ship determination.

On the pirate ship determination setting screen displayed through the display module 220, for example, a navigation vessel, a navigation buoy, etc. around the ship may be displayed based on radar signals and various measurement signals received from the monitoring unit 110. Relative position information and its course and speed according to azimuth and distance of surrounding vessels based on the position may be displayed.

The pirate ship setting module 230 receives and manages setting information for determining a pirate ship according to a user operation using a user interface (UI) for analyzing a pirate ship, which is generally a small vessel of a boat type.

For example, since pirate ships have a small size and high speed to effectively approach the target ship compared to general ships, the setting information used as the pirate ship judgment factor includes the width (WIDTH), speed (SPEED) and One or more of the CPA (Closest Point of Approach) may be included.

In addition, the pirate ship setting module 230 may differentially set individual risk setting values of each judgment element by a user operation, and a risk reference value for comparison with the final risk and the final risk calculated by the combination of individual risks according to each judgment element. Can be set.

Here, the meaning of the risk setting value for each pirate ship determination element, the meaning of the risk reference value, and the use thereof will be described together in the following description of the determination module 270. However, in the present embodiment, for convenience of description, it is assumed that the speed and the CPA of the surrounding vessel are described among various pirate ship determination factors, but the determination factor is not limited thereto.

The image management module 240 collects image information generated by each camera included in the camera unit 120 and stores image data corresponding to the collected image information in the storage module 250.

If the image management module 240 determines that the current situation is a dangerous situation (for example, the appearance of a pirate ship) by the determination module 270, the image stored in the storage module 250 under the control of the determination module 270. The data is transmitted to the designated control server 150 through the communication module 260.

When the camera designation information is received from the control server 150, the image management module 240 may process the image data corresponding to the camera designation information to be transmitted to the control server 150.

The storage module 250 stores various setting data and programs for determining a pirate ship, and records various monitoring information and calculation data collected and generated according to surrounding vessel monitoring in a time series. In addition, the storage module 250 stores image data corresponding to image information received in real time from the camera unit 120.

Communication module 260 is a pirate ship alarm and / or storage module using one or more of the satellite communication system (Satellite communication system, Very high frequency (VHF) communication equipment that can communicate with the land using satellite equipment, etc. The video data stored in the 250 is transmitted to the control server 150 provided in the land and / or other vessels.

The determination module 270 calculates a speed and a CPA value for each of the surrounding vessels based on the monitoring information of the surrounding vessels provided from the monitoring unit 110 and stores the calculated values in the storage module 250.

In addition, the determination module 270 calculates the weighted final risk by combining the stored speed and the CPA value of the surrounding vessel, and displays the final risk for each peripheral vessel through the display module 220.

At this time, the determination module 270 may compare the final risk and the risk reference value of each peripheral vessel to determine and display and alert a vessel having the final risk level higher than the reference value as a pirate ship, and the image data stored in the storage module 250 The image management module 240 may be controlled to be transmitted to the control server 150 through a communication network.

FIG. 3 illustrates a risk calculation method based on a close point of approach (CPA) of a surrounding ship, and FIG. 4 illustrates a risk calculation method based on a speed of a surrounding ship.

Hereinafter, the embodiment will be described based on the calculation of the risk of the surrounding vessel for determining whether the surrounding vessel is a pirate ship in consideration of the CPA and the speed, but as described above, the determination factor for calculating the risk for the vessel is not limited thereto. Of course, the width of the surrounding vessel (WIDTH) may be included more.

3 and 4, the risk by the CPA (see FIG. 3) of the surrounding vessel may be numerically represented by any value between 0 and 225, for example, and the risk by speed (see FIG. 4). For example, it may be represented by any value of 0 to 255. Larger risk values can be interpreted as more dangerous.

In the case of the vessel A shown in FIGS. 3 and 4, the risk may be calculated as 102 because the CPA value is 1.8 (NM), and the risk may be calculated as 255 since the speed is 24 (KN). have.

The determination module 270 calculates the final risk by weighting each risk according to the CPA value and the speed, which are the determination factors, and assumes that the weight is set to 40% CPA and 60% speed, respectively. The final risk of is calculated as 194 (ie, the final risk of ship A = (102 * 0.4) + (255 * 0.6) = 194).

Here, the weight is set by the pirate ship setting module 230 is input from the user through the user interface (UI), it may be set according to the importance of the determination factor on the pirate ship determination.

Similarly, in the case of the vessel B shown in FIGS. 3 and 4, the CPA value is 0.5 (NM) and thus the risk may be calculated as 204, and the speed is 20 (KN) and thus the risk is calculated as 255. Can be.

In addition, as in the case of ship A, the determination module 270 applies a weight set to 40% CPA and 60% speed so that the final risk of the ship B is 235 (that is, the final risk of the ship B). (204 * 0.4) + (255 * 0.6) = 235).

Here, when comparing only the final risks of the two vessels, the final risk of the vessel (A) is 194 and the final risk of the vessel (B) is 235, so that the vessel (B) may be judged as a dangerous vessel compared to the vessel (A). have.

The determination module 270 of the integrated management unit 200 compares the final risk value of each ship with a preset risk reference value and generates a dangerous ship occurrence alarm when the final risk is greater and / or stores the image data stored in the storage module 250. The transfer can be performed.

At this time, it is natural that the risk warning step may be specified in plural and the risk reference value may be differentially set at each risk step so that a corresponding risk situation response may be performed.

 For example, the critical alert level can be set to HIGH (for example, at least 204 or at least 80% of 255), MIDDLE (for example, at or above 166, or at least 65% of 255), or LOW (for example, For example, risk 102 or more or 40% of the highest risk 255), and the video data transmission to the control server 150 may be performed only in the high risk alarm stage, the risk that occurs in each risk alarm stage Different types of ship-borne alarms (e.g. wave sounds at the HIGH level, flat sound at the MIDDLE level, etc.) may be differentiated. Of course, there will be a variety of ways to respond to the risk situation in each stage of the hazard warning.

Applying the risk warning step illustrated above, in the case of the vessel (A) shown in Figs. 3 and 4, since the final risk is 194, the risk situation response processing corresponding to the MIDDLE level is performed, and in the case of the vessel (B) As the final risk is 235, the risk response processing corresponding to the high level can be performed.

As such, the determination module 270 may automatically calculate the final risk by weighting each risk according to the CPA and the speed of the neighboring vessels, and perform the differential level risk alarm by comparing the final risk with the risk reference value. .

However, the determination of whether the surrounding vessel of the determination module 270 is a pirate ship is based on a determination element (for example, the width of the ship, which the user inputs using a user interface (UI) corresponding to the pirate ship setting module 230). CPA, speed, etc.), depending on the weight, etc., the risk calculation for the surrounding vessels of the determination module 270 and the pirate ship by changing the setting information for judging the pirate ship input according to the user's operation Criteria may vary.

Hereinafter, a process of changing the risk of nearby vessels according to the change of the setting of the CPA and the speed among the pirate ship determination elements will be described with reference to FIGS. 5 and 6.

FIG. 6 shows a change in the risk of a vessel when the user changes only the setting value of CPA, which is a pirate ship judgment element, from 3 (NM) (see X axis in FIG. 3) to 5 (NM) (see X axis in FIG. 5). The process is shown.

When the risk of the ship A is calculated by applying the criteria shown in FIG. 6, the risk is calculated as 153 because the CPA value is 1.8 (NM), and the speed is 24 (KN) because there is no change in the set value for the speed. Therefore, the risk may be calculated as 255 as shown in FIG. 4.

The determination module 270 calculates the final risk by weighting each risk according to the CPA value and the speed, which is the determination factor. As described above, if the weight is set to 40% CPA and 60% speed, the vessel A ) Is calculated as 214 (i.e., final risk of vessel A = (153 * 0.4) + (255 * 0.6) = 214).

As such, when the user changes only the setting value of the CPA, which is the pirate ship determination element, from 3 (NM) to 5 (NM), the determination module 270 calculates the final risk of the ship A to be changed from 194 to 214. In this case, the hazard warning stage for the vessel A shown in FIGS. 3 and 4 was managed at the MIDDLE level, but the hazard alert stage of the vessel A shown in FIG. 5 is changed to HIGH.

That is, even if the vessel has the same CPA value (eg, 1.8 NM), the risk may be determined differently according to the setting information managed by the pirate ship setting module 230.

FIG. 7 illustrates a process of changing the risk level when the setting of the determination element for the speed of the setting information is changed. That is, when the speed setting value of the setting information managed by the pirate ship setting module 230 is changed from 30 (KN) to 10 (KN), the risk of the ship represents a change process.

For example, when the CPA value of the vessel C is 1.8 (NM) and the speed is 10 (KN), the risk of each judgment factor before the speed setpoint change is calculated.The CPA value is 1.8 (NM). May be calculated as 102 (see FIG. 3), and the risk may be calculated as 50 (see dotted line graph before the change in FIG. 6) since the speed is 10 (KN).

Assuming that the weight given by the judgment module 270 to calculate the final risk is set to 40% CPA and 60% speed, the final risk of the ship C is 71 (ie, the final risk of the ship A = (102 * 0.4) + (50 * 0.6) = 71).

However, if the user changes the speed setting value from the existing 50 (KN) to 30 (KN), the risk of the ship C is CPA value of 1.8 (NM), so the risk accordingly is 102 (see FIG. 3). Since the speed is 10 (KN), the risk may be calculated as 255 (refer to the solid line graph after the change in FIG. 6), respectively.

Further, applying the same weight to calculate the final risk, the final risk of ship c is calculated as 194 (i.e., the final risk of ship C = (102 * 0.4) + (255 * 0.6) = 194). .

In this way, the final risk of the ship c is changed from 74 to 194 by the change of the setting information, and the danger warning stage is also changed from the safety level to the middle level. That is, even if the vessel has the same speed (eg 10 KN), the risk is evaluated differently by changing the speed setting value managed by the pirate ship setting module 230.

Referring back to FIG. 1, the counterpart unit 140 of the image data transmission apparatus 100 may be a water canon capable of remotely operating as a device for preventing pirates from boarding when a pirate ship approaches the main ship within a certain distance. It may include one or more of a water shutter and a remote controller.

The water cannon fires the water cannon toward the pirate ship according to a control signal applied from the integrated management unit 200. The water canon may include, for example, driving means for changing the water nozzle for firing the water cannon in the up, down, left and right directions.

The water shutter sprays hot water to flow outside the ship's hull according to an applied control signal to prevent pirates from climbing on the ship.

The remote controller can be connected to corresponding devices such as water cannon and water shutter by wire or wireless communication, and can control the operation of each corresponding device by using an operation module such as a joystick in a relatively safe place such as a steering wheel.

7 is a flowchart illustrating a pirate ship determination and image data transmission method according to an embodiment of the present invention.

Referring to FIG. 7, when the pirate ship monitoring is started by the integrated management unit 130, in operation 710, the user uses a user interface (UI) managed by the pirate ship setting module 230 and displayed through the display module 220. Adjust the setting function for determining whether or not pirate ships. Step 710 may not necessarily be an essential step, and may be selectively performed at a time required by the user.

The user may perform one or more of the input of the CPA change value, the speed change value input, the weight change according to the importance of the determination element, etc., through the adjustment step of the setting function of step 710, and the pirate ship setting module 230 is inputted. Update configuration information for risk calculation to correspond to the information.

Integrated management unit 130 collects the monitoring information of at least one of the position, course, speed, etc. of the main ship and the surrounding vessels from the monitoring unit 110 in step 720, and calculates and stores the speed and CPA value of the surrounding vessels in step 730 do.

In step 740, the integrated management unit 130 calculates the risk for each determination element for the surrounding vessel using the calculated speed and CPA value. That is, the integrated management unit 130 calculates each individual risk by comparing the calculated speed and the CPA value with the setting information managed by the pirate ship setting module 230.

The integrated management unit 130 calculates the final risk for each neighboring vessel by applying weights given according to the importance of the determination factor to the individual risks calculated for each neighboring vessel in step 750, and adding the weighted individual risks. .

In step 760, the integrated management unit 130 compares the final risk reference value of the surrounding vessels with the preset risk reference value for determining the pirate ship.

If the calculated final risk is less than or equal to the risk threshold, it is determined that there is no risk and the process proceeds to step 710 again.

However, if the calculated final risk is greater than or equal to the risk reference value, the process proceeds to step 780 to perform image data transmission to the dangerous ship occurrence alarm and / or control center 150 according to the risk alert level corresponding to the calculated final risk.

The image data to be transmitted to the control center 150 through step 780 is provided to the integrated management unit 130 is provided with the image information corresponding to the installation location from the camera unit 120 regardless of whether the pirate ship monitoring is performed to the storage module 250 (Step 760).

Of course, the image information collected from the camera unit 120 may be used only for display through the display module 220 without being stored in the storage module 250 in a safe state. Naturally, the encoding process may be further performed to store the image data corresponding to the image information in the storage module 250.

8 is a diagram illustrating a selective transmission method of image data according to an embodiment of the present invention.

Referring to FIG. 8, in operation 810, the integrated management unit 130 determines that the current state is a dangerous state due to the appearance of a pirate ship, and previews the image data stored in the dangerous ship occurrence alarm and / or storage module 250 through a communication network. Send to the designated control server 150.

In this case, the image data transmitted to the control server 150 may be image data regarding captured images of all the camera apparatuses included in the camera unit 120, but the captured image of the predetermined basic camera apparatus (for example, inside the steering room). Image data).

In operation 820, the integrated management unit 130 determines whether camera designation information, which is designation information for any camera device, is received from the control server 150.

The camera designation information may be, for example, identification information uniquely designated for each camera device. The operator of the remote control server 150 can select the camera device providing the captured image to check among a plurality of camera devices provided on the ship by allowing the camera designation information is transmitted to the integrated management unit 130 through the communication network. In this way, the current state of the ship can be confirmed more accurately and variously, and accurate and rapid response to dangerous situations can be achieved.

If the camera designation information is not received, the process returns to step 810 to periodically transmit a dangerous ship occurrence alarm to the control server 150 or maintain the transmission state of the image data.

However, if the camera designation information is received, the integrated management unit 130 reads out the video data corresponding to the received camera designation information among the video data stored in the storage module 250 in real time in step 830 and the control server ( 150).

Of course, the above-described method for transmitting ship image data in a dangerous situation may be performed by an automated procedure according to a time series sequence by a program embedded in or installed in a 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.
