Description

Intelligent ship warning system {SYSTEM OF WARNING FOR SHIP}

The present invention relates to an alarm system for multiple intelligent ships, and more particularly, a technology in which a crew member or a passenger falls over a railing or detects an alarm and automatically notifies when an intruder enters a rail over the railing. It is about.

In modern society, ships are used for various purposes such as travel, cargo transportation, and national defense. In addition, a ship may be classified into a passenger transport ship carrying passengers, a passenger transport ship carrying passengers and cargo, a freight ship carrying cargoes, and a commercial ship used for commercial purposes, depending on the purpose of use.

Vessels rarely encounter pirates during sailing or berths. In the past, pirates sneaked into ships to steal ship's equipment, but in recent years, pirates have begun to use pistols, rifles, and automatic weapons. Hostages or seizing ships began to take place.

In addition, pirates have recently become more cruel, hijacking or even killing crew.

However, in the conventional case, when a ship encounters a pirate, the ship uses a ship security alarm device or wireless communication to contact the headquarters and the maritime police of the offshore country, and has made a very passive defense by moving the ship greatly.

On the other hand, the crew members on board the ship may fall outside the ship as the ship encounters an abnormal climate phenomenon such as a typhoon depending on the place where the ship is sailing.

In this case, if a fellow crew detects a crash, immediate rescue can occur, but if no one finds it, immediate relief is difficult, leading to a casualty.

Korean Patent Publication No. 2011-0092555 discloses a device and method for preventing pirate intrusion, but the technique disclosed in the Korean Patent Publication discloses an emergency situation by sound and automatically controls the operating route of the vessel. It is difficult to grasp the emergency visually, and there is a limit such as an expensive device is required because a separate control device must be provided to control the operation of the ship.

Therefore, there is an urgent need for new technologies that can immediately recognize the situation occurring inside or outside the vessel.

An object of the present invention is to compare the image frame before and after sequentially analyzing the image frame (Frame) coming through the CCTV mounted toward the railing of the ship, and to analyze the size, color, moving direction, speed, etc. of the object (object) It is to provide an alarm system that can identify whether an emergency occurs by distinguishing whether a person is a person and tracking the movement of an object assumed to be a person.

In addition, the object of the present invention is to set the detection boundary to the computer on the railing of the ship shown on the screen of the CCTV, and when the person enters the vessel when passing through the perimeter, the event is set to fall into the trespass when passing through, When an event occurs, an alarm system, such as a speaker or a warning light, provides an alarm system that immediately informs the monitor of an alarm signal.

In addition, the object of the present invention is not only to accurately detect a person when crossing the boundary line, but also to detect false detection by separating waves and rain, snow, light, floats, etc. from people in order to reduce false alarms, and detection at night. It is to provide an alarm system that can be properly exercised.

The present invention will now be described in detail with reference to the accompanying drawings. Here, the repeated descriptions and detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a state of monitoring the periphery of the vessel by the intelligent vessel fall and intrusion alarm system according to an embodiment of the present invention.

Intelligent vessel fall and intrusion alarm system according to an embodiment of the present invention is configured to include a front monitoring unit 100, rear monitoring unit 200, side monitoring unit 300 and the video surveillance system (1000).

The front monitoring unit 100, the rear monitoring unit 200 and the side monitoring unit 300 are respectively installed on the front, rear and side of the vessel to collect the image around the vessel.

The video surveillance system 1000 generates an internal boundary line 10 or an external boundary line 20 in an image collected from the front monitoring unit 100, the rear monitoring unit 200, and the side monitoring unit 300. 10) or an alarm is generated by detecting an abnormal situation generated around the external boundary line 20.

Hereinafter, the front monitoring unit 100, the rear monitoring unit 200 and the side monitoring unit 300 is also referred to as a "monitoring unit."

Hereinafter, the internal boundary line 10 and the external boundary line 20 are also referred to as 'virtual boundary lines'.

The process through the video surveillance system 1000 is composed of a three-step process of detection, analysis, and alarm.

Analyzing the image collected by the monitoring unit (100, 200, 300) installed in the vessel, and recognizes the object, when the object approaches the vicinity of the virtual boundary line (10, 20), the primary alarm.

After the object is out of a certain distance in the vicinity of the virtual boundary line (10, 20), the alarm is released.

In particular, when an object recognized as a person approaches near the virtual boundary lines 10 and 20, it may be an intrusion into the ship from the outside or a fall situation that leaves the outside, and thus measures may be taken.

As shown in FIG. 1, when the internal boundary line 10 is set to a virtual line having a predetermined distance from the ship's rail, the primary alarm when a person approaches the internal boundary line 10, that is, near the railing. If the object moves to a safe area inside the railing, the alarm will be canceled again.

However, if it is detected that a person has crossed the railing and out of the ship, a second alarm is issued. In this case, a warning lamp or a speaker can be reliably sent to the monitor to indicate that an abnormal situation has occurred.

On the contrary, when an object suspected to be a person invading the inner boundary line 10 during the operation or anchoring of the vessel, a second alarm can be immediately triggered so that the monitors can take appropriate measures.

In addition, when the outer boundary line 20 is set to a virtual line having a distance farther from the vessel than the inner boundary line 10, the alarm is primarily alarmed when an object suspected from the outside of the outer boundary line 20 approaches. And, when the object passes through the external boundary line 20 inside, it is determined that the intrusion situation, after passing an alarm to the monitor can inform that the abnormal situation has occurred.

At this time, in installing the monitoring unit 100, 200, 300, the monitoring unit 100, 200, 300 by adjusting the position to install the monitoring unit (100, 200, 300) on the vessel according to the shooting angle of the monitoring The region may include all of the inner regions of the virtual boundary lines 10 and 20.

In FIG. 1, the monitoring areas of the monitoring units 100, 200, and 300 are located adjacent to each other in the vicinity of the external boundary line 20 so as to block the external intrusion, so that an object may be approached from anywhere near the ship. The monitoring unit 100, 200, 300 may be installed on the ship so as to be exposed to the area.

In the same principle, referring to FIG. 2, in order to prepare for a situation of falling from the inside to the outside, the monitoring areas of each of the monitoring units 100, 200, and 300 are positioned to be adjacent to each other near the internal boundary line 10. For example, the monitoring unit 100, 200, 300 may be installed on the vessel so that the object may be exposed to the surveillance region even if the object approaches from anywhere inside the vessel.

In this way, the position of the monitoring unit (100, 200, 300) can be appropriately modified and applied according to the operating method, such as intrusion or fall, and can be prepared for intrusion or fall selectively or intrusion and fall at the same time.

To this end, by analyzing the shape of the vessel to install the monitoring unit (100, 200, 300), calculate the installation position, installation height, angle of the monitoring unit (100, 200, 300) can be reflected in the alarm system design and installation have.

In addition, it can be waterproofed to reflect the situation of the sea, or can be properly fixed and installed so as not to be affected by the shaking of the ship.

When installing the monitoring unit (100, 200, 300) in the case of the front monitoring unit 100 and rear monitoring unit 200 is installed in a position that can easily see the front and rear situation, in the case of the side monitoring unit 300 It can be installed by adjusting the proper height and angle so that the ship's railing can be fixed on the screen.

In addition, the monitoring unit (100, 200, 300) according to the operating method may apply a high-resolution camera, the camera with an IR function that can be photographed at night.

At this time, the monitoring unit (100, 200, 300) may be used as a pair of a fixed CCTV camera and a PTZ (pan tilt zoom) camera for proper monitoring of the moving object.

In the case of a PTZ camera installed in pairs with a fixed CCTV camera, it can be organically linked with a fixed CCTV camera based on a PTZ function capable of tracking an object.

In this case, the fixed camera transmits the position coordinates of the detected object to the same pair of PTZ cameras, and the PTZ camera tracks the position of the object based on the information received from the fixed camera, and interlocks the information with other PTZ cameras in some cases. You can keep track of things in a relay way.

In addition, the monitoring unit (100, 200, 300) to remove the fog and increase the sharpness by using the image restoration technology when the image from the high-resolution camera fog, and outputs this to the person in charge when abnormal objects are detected around the ship You can try to understand the maritime situation.

In this case, the image restoration technology may derive the necessary image by using an algorithm for discriminating a person and an object (waves, light, floats, etc.).

In particular, by using image restoration technology in the misty area, it is possible to induce a safe operation by providing a vividly restored image to ensure a relatively excellent view even in bad weather.

Clearly reconstructed images using image reconstruction techniques reveal whether external objects that are not caught by the radar are approaching.

The image monitoring unit 1020 may generate a virtual boundary line in the image collected by the image collecting unit 1010 and recognize an object appearing around the virtual boundary line.

In this case, the virtual boundary line may be generated by dividing the inner boundary line and the outer boundary line according to the distance to the vessel.

The image storage unit 1030 stores the image collected through the monitoring unit 100, 200, 300.

At this time, if the storage space exceeds a certain level, it can be operated to further secure the storage space by first deleting the stored image.

The image analyzer 1040 may classify the type of abnormal situation as a case in which the object moves from the outside to the inside of the virtual boundary line and the case in which the object moves from the inside to the outside.

At this time, the inner boundary line may be set as a virtual line having a predetermined distance from the ship's rail, and the outer boundary line may be set as a virtual line having a distance farther from the vessel than the inner boundary line 10.

The monitoring unit 1050 may output an image collected from the monitoring units 100, 200, and 300 to the monitor as sound and image.

At this time, the collected image may be divided into the partitioned image collected by the monitoring unit 1050 may be output in the form of several channels.

Alternatively, the positions of the monitoring units 100, 200, and 300 installed on the screens of the types of vessels are displayed as symbols, and when an abnormal situation occurs, event contents are displayed on the symbols of the corresponding monitoring units 100, 200, and 300. If you click it with the mouse, you can output the window of the corresponding screen.

In this case, the one monitoring unit 1050 may be separately displayed on the monitoring unit 1050 classified by the menu method.

The warning transmission unit 1055 may notify the related organization of the occurrence of the abnormal situation according to the kind of the abnormal situation.

In the case of a fall situation, the rescue team can be notified of the fall situation so that the rescue can be made quickly.In the case of an intrusion situation, the marine police, military or government agencies can be notified of the intrusion situation so that rapid follow-up can be made.

The communication unit 1060 may transmit abnormal situation information regarding the type and time of occurrence of the abnormal situation to the monitor's portable terminal through the mobile communication network.

The location tracking unit 1070 analyzes the coordinate information of the object appearing in the image collected through the monitoring unit 100, 200, 300, and when the object moves to the outside of the monitoring area of one of the plurality of monitoring units. By passing the coordinate information of the object to another monitoring unit, the object can be continuously tracked.

At this time, the monitoring unit (100, 200, 300) can be mixed with the fixed camera and the PTZ camera, the fixed camera transmits the position coordinates of the detected object to the same pair of PTZ camera through the position tracking unit 1070 The PTZ camera tracks the position of the object based on the information received from the fixed camera, and in some cases, the object can be continuously tracked in a relay manner by linking information with other PTZ cameras.

When an object approaches or passes through the virtual boundary line, the alarm generation unit 1080 may notify the monitor of an alarm signal through an alarm device such as a speaker or a warning light that an intrusion or fall situation has occurred depending on the type of abnormal situation.
