Description

Automatic Leveling 360-Degree Monitoring Video Black Box Device for Ships

[0001] The present invention relates to an automatic leveling video black box device for ships, and more specifically, to an automatic leveling 360-degree monitoring video black box device for ships equipped with a mechanical leveling device of a 2-axis mechanical gimbal that corrects the shaking of the ship's pitch and roll axes to maintain leveling during rolling and pitching of a ship operating on the sea for safe navigation of the ship, a video black box housing is provided on the upper part of a 2-axis mechanical gimbal (mechanical leveling device) that corrects the shaking of the ship's pitch and roll axes in order to maintain leveling during rolling and pitching of a ship operating on the sea for safe navigation of the ship, sharp needles are provided on the upper part of the video black box housing to prevent the approach of birds, and a video black box device equipped with a GPS, a control unit, and 1 to 4 cameras capable of 360° omnidirectional shooting is provided inside the video black box housing to record video occurring during ship operation and analyze the cause of the accident based on the video, thereby enabling a rapid response in the event of a ship accident.

[0002] A ship sailing on the sea undergoes three linear motions and three rotational motions due to the motion received from the waves.

[0003] When a periodically changing force in the forward and backward direction is applied to a ship, the ship moves in the forward and backward direction due to surge, and similarly, when a force in the left-right and up-down direction is applied to the ship, the ship moves in the left-right and up-down directions due to sway and heave.

[0004] In addition, if a rotational moment about the X-axis is applied periodically to the ship, the ship rotates about the X-axis by rolling, and if a rotational moment about the Y-axis and Z-axis is applied to the ship, the ship is called pitch and yaw.

[0005] (1) Linear motion

[0006] - Surge: X-axis (forehead / tail direction)

[0007] - Sway : Y-axis (width direction)

[0008] - Hwave : Z-axis (vertical direction)

[0009] (2) Rotational motion

[0010] - Roll: X-axis (rotation in the length direction)

[0011] - Pitch: Y-axis (rotation in width direction)

[0012] - Yaw: Z-axis (vertical rotation)

[0013] Ships operate in seas where waves are always present, and hull motion performance must be improved for the safety of passengers, crew, cargo, and the ship itself.

[0014] For the safety of the ship, the roll during the movement of the hull must be controlled to be maintained within a specific range. To this end, a passive or semi-active anti-rolling tank (ART) is used. The anti-rolling tank reduces roll by installing a U-shaped water tank in the center of the ship and utilizing the resonance phenomenon of the flow inside the water tank.

[0015] The ship's anti-rolling tank (ART) is used as a roll damping device that reduces rolling, or roll.

[0016] As prior art related to this, Patent No. 10-2107168, "Black box device for ships" is registered.

[0027] Figure 2 is a diagram showing the types and causes of ship accidents.

[0028] Ship accidents are on a continuous upward trend, increasing by approximately 7.6% compared to the previous year, with fishing vessels showing the highest increase rate (19.1%).

[0029] The causes of ship accidents include equipment failure, equipment damage and operational negligence, maintenance deterioration, fuel depletion, careless handling of fire, improper loading, and poor materials. The biggest issue among the causes of ship accidents is “negligence during operation,” which demonstrates the necessity of “consistent real-time monitoring” of ship operations.

[0030] A Voyage Data Recorder (VDR) primarily records only operational information (route, speed, weather data, voice communications, etc.) and does not provide real-time video monitoring capabilities or record actual visual information. For example, in the event of a maritime collision, external conditions cannot be visually verified, which limits the ability to clearly analyze the accident situation and can make it difficult to determine liability. VDR equipment is expensive, and significant costs are incurred during the installation process, particularly for large vessels. This is because the technical requirements for the installation and operation of VDRs are very high. In particular, older vessels frequently fail to fully comply with legal regulations due to the limitations of outdated technology.

[0031] The Automatic Identification System (AIS) is a navigation system that automatically transmits and receives ship information between ships and between ships and land via wireless communication to ensure navigational safety. It provides data such as ship name, type, specifications, location, sailing speed, and route, and is utilized for port control by collecting and providing accurate ship location information, as well as to support search and rescue operations in the event of maritime accidents.

[0032] The marine VHF used by the Automatic Identification System (AIS) primarily utilizes the 156 MHz to 174 MHz band. However, due to bandwidth limitations of the 30 MHz to 300 MHz range, it is practically very difficult to transmit video signals with very large data capacities. Since VHF only enables relatively low-speed data transmission, it is mainly used for voice communication, emergency calls, and navigation safety.

[0033] However, vessels can intentionally turn off their Automatic Identification System (AIS) or transmit false information to conceal their location. Camouflage and signal jamming can be used to conceal smuggling, illegal fishing, and piracy, posing a threat to maritime safety. Real-time monitoring is essential to address these issues.

[0034] AIS data is entered by ship crews with information such as ship name, destination, and speed; however, inaccurate information may be entered, whether intentionally or accidentally, and if entered incorrectly, the reliability of the systems using that data decreases.

[0035] Actions by crew members that damage ship equipment through careless handling can result in financial losses for the shipowner. Furthermore, if crew members fail to properly use onboard safety equipment or violate safety regulations, it can lead to accidents, pose serious risks to ship operations, and cause legal liability and insurance claim issues. Legal problems related to the vessel arise even if the shipowner is not directly involved, such as crew members illegally smuggling goods, engaging in illicit trade with outsiders, embezzling catches, or illegally dumping waste. Additionally, it is illegal for a vessel to fish during a closed season or capture protected species, and such illegal fishing activities can lead to legal issues for both the vessel and the shipowner.

[0075] - Vessels with a gross tonnage of 500 tons or more that are not engaged in international voyages

[0076] - Vessels with a gross tonnage of 50 tons or more navigating beyond coastal areas

[0077] - Fishing vessels with a gross tonnage of 10 tons or more (excluding inland fishing vessels and vessels engaged in fishery management within 5 miles of the coast)

[0078] Figure 2a is a diagram showing the types and causes of ship accidents.

[0079] While AIS and VDR information indicates a vessel's navigation status, it cannot reveal specific situations occurring inside the ship (e.g., crew behavior, internal issues). This is a significant issue, as the limitations of this information make it difficult for the Coast Guard to conduct effective investigations into the causes of accidents or illegal activities.

[0080] Both VDR and AIS are primarily used to assist in post-accident investigations or to track the location of ships, but there are limitations in monitoring illegal activities of the crew on board in real time when a ship intentionally disregards safety regulations or tamperes with equipment.

[0081] Furthermore, real-time video surveillance inside the vessel is the best method to fundamentally prevent illegal activities that may occur on board.

[0082] However, under international law, large vessels are required to be equipped with Voyage Data Recorders (VDRs). Yet, because VDRs are so expensive, they are very difficult to use on small vessels such as fishing boats.

[0083] Large vessels are equipped with Voyage Data Recorders (VDRs) and Automatic Identification Systems (AIS), but small vessels weighing 2 tons or more are required to install video black boxes. Video black boxes are necessary to monitor and analyze camera footage to identify the primary causes of maritime distress, collisions, and capsizing accidents.

[0084] Figure 2b is a drawing showing the necessity of a video black box for ships.

[0085] Unlike automotive dashcams, which are frequently involved in traffic accidents, maritime accidents involving vessels are relatively rare. Furthermore, because ships move significantly due to waves, wind, and weather conditions while underway, the camera footage from marine video dashcams often shakes or becomes distorted due to the vessel's movement, resulting in low-resolution video. While existing electronic gimbals are required to resolve this shaking issue, they are not yet being used on vessels due to the various problems outlined below.

[0086] Problems with existing electronic gimbals

[0087] 1) Vibration and instability

[0088] If the axes of an electronic gimbal are separated, vibration is highly likely to occur because each axis has a different center of rotation. This can degrade the quality of video or sensor data and reduce stability, making it difficult to achieve the desired performance.

[0089] 2) Complex calibration and control

[0090] If the axes of an electronic gimbal are separated, it becomes difficult to control each axis individually, requiring additional calculations and control algorithms to compensate. This increases system complexity and reduces real-time responsiveness.

[0091] 3) Increase in volume and weight

[0092] The separated axis structure of an electronic gimbal can be mechanically complex, which may result in an increase in the size and weight of the entire gimbal system. This becomes a limiting factor for camera size and weight.

[0093] 4) Increased power consumption

[0094] If the axes of an electronic gimbal are separated, more power is consumed to control each axis. This becomes a significant issue in battery-powered drive systems.

[0095] Extreme marine environments (waves, strong winds, high pressure, low temperatures, seawater corrosion, etc.) make the conditions that marine video black boxes must withstand much more demanding. Since cameras shake significantly at sea due to factors such as waves and typhoons, a stable camera video transmission system that prevents shake is essential to maintain video quality.

[0119] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings, including the structure and operation of the invention.

[0120] The present invention is not limited to the disclosed embodiments and may be implemented in various different forms by those skilled in the art. In the description of the present invention, detailed descriptions of related known technologies or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the invention. Additionally, the same drawing numbers are assigned in different drawings when indicating the same configuration.

[0121] This study is not limited to specific embodiments and should be understood to include all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0122] The marine video black box device equipped with a mechanical leveling device of a 2-axis mechanical gimbal according to the present invention is equipped with a 2-axis mechanical gimbal (mechanical leveling device) that corrects the shaking of the ship in the Pitch and Roll axes in order to maintain the horizontal level of Rolling and Pitching of the ship operating on the sea for safe navigation of the ship, and is equipped with a video black box housing on the upper part of the mechanical leveling device of the 2-axis mechanical gimbal, and is equipped with sharp spikes on the upper part of the video black box housing to prevent birds from approaching, and is equipped with a GPS, a control unit, and 1 to 4 cameras capable of 360° omnidirectional shooting inside the video black box housing, thereby recording video occurring during ship operation, accurately analyzing the cause of the accident based on the video to prevent recurrence, and enabling a rapid response.

[0123] The marine video black box device uses 1 to 4 cameras within the video black box housing and is used in conjunction with one cabin interior camera (dome camera).

[0124] The leveling device of the marine video black box device uses a 2-axis mechanical gimbal that corrects shaking of the ship's pitch and roll axes in order to maintain levelness during rolling and pitching while the ship is operating at sea.

[0125] FIG. 3a is a solution for a marine video black box equipped with a GPS and a video black box housing with an IP67 or higher rating, using a circular 2-axis mechanical gimbal to implement the present invention, and FIG. 3b to 3f are drawings showing the configuration of a marine black box device equipped with a mechanical leveling device.

[0126] * Specific configuration and connection relationships of the leveling device

[0127] (1) A small circular center-integrated gimbal is contained inside the cylinder of the ship's round column.

[0128] (2) The sphere of the 2-axis mechanical gimbal is cut horizontally at the top, so that the gimbal's center of gravity is positioned at the bottom. The center of gravity at the bottom ensures that the gimbal's restoring force always acts in the opposite direction of the movement when the ship rolls or pitches, allowing the gimbal's camera to maintain a horizontal position. This ensures that the black box video always maintains the same field of view.

[0129] (3) Three bearings are installed in the horizontal axis of the gimbal, two of which are inserted horizontally to the left and right, and the remaining one is inserted vertically downward. The two horizontal bearings are inserted into the sides of the circular body to support the gimbal horizontally, and the remaining bearing inserted vertically downward supports the gimbal upward.

[0130] (4) The cylinder has bearing rails in two directions (left and right) to prevent the gimbal from rotating 360 degrees.

[0131] (5) Oil is placed between the cylinder and the gimbal, and due to the viscosity of the oil, the gimbal moves slowly and smoothly.

[0132] (6) A connecting rod for mounting the housing is inserted into the upper part of the gimbal.

[0133] (7) A video black box housing is mounted on top of the gimbal, and the connection between the gimbal and the housing is covered with a hood to prevent seawater from entering the connection area when it rains or the waves are strong.

[0134] (8) 1 to 4 cameras, a control unit (MCU), and a GPS are installed inside the video black box housing. The MCU controls the 4 cameras and sends the video from the 4 cameras and the location information from the GPS to the switch in the cabin.

[0135] (9) Sharp spikes are installed on the top outer surface of the video black box housing to prevent birds from approaching.

[0136] Referring to the centroids of the gimbal axes in Fig. 3e, conventional gimbals have separate axes, so the centroids of each axis are independent. This means that the movement of one axis affects the movement of another axis. In other words, if movement occurs in one axis, vibration may occur in the other axis. Such vibration becomes more severe as the number of axes and centroids increases. The occurrence of such vibration is a major cause of degraded camera image quality and can lead to malfunction.

[0137] The 2-axis mechanical gimbal of the present invention has two axes with only one centripetal point centered around a single sphere. A gimbal with a single centripetal point maintains stability as all axes move around that single centripetal point. Therefore, even when moving across multiple axes, vibration does not occur because the movement is integrated around a single centripetal point. This maintains the quality of the camera image and the durability of the camera.

[0138] Electronic gimbals and mechanical gimbals

[0139] Electronic gimbals use gyroscopes and accelerometers to detect and analyze equipment movement in real time. Motors located on each axis instantly correct the detected tilt and rotation to minimize camera shake. Since the sensors and motors are connected in real time, they provide immediate feedback to precisely control camera shake.

[0140] Electronic gimbals are equipped with batteries and motors at each of the three focal points 1, 2, and 3. Since power is required to operate the motors and sensors, battery life is limited, and because they include motors, sensors, and batteries, they are heavier and bulkier than mechanical gimbals.

[0141] The 2-axis mechanical gimbal of the present invention reduces shaking by achieving physical balance without motors or sensors, and each axis can move independently or around a single center point. That is, it stabilizes the camera by utilizing gravity and inertia to balance it.

[0142] 2-axis mechanical gimbals are composed entirely of mechanical parts, making them easy to maintain and highly durable. Since they do not use batteries, they allow for long-term continuous use and offer excellent energy efficiency. Mechanical gimbals are advantageous in situations where durability, energy efficiency, and extended operation are critical, and they have the advantage of stable operation in extreme environments with significant shock or vibration, such as ships.

[0143] Correction and control using gravity and inertia

[0144] If the gimbal's axes are separated, it becomes difficult to control each axis individually, requiring additional calculations and control algorithms to compensate. This increases the system's software complexity and reduces real-time responsiveness.

[0145] The 2-axis mechanical gimbal of the present invention naturally controls the balance of the equipment by utilizing gravity and inertial force. In addition, the center of gravity of the equipment is located low, which helps stabilize it when shaking occurs.

[0146] Unlike electronic gimbals, it is controlled passively without electricity, so it does not require separate, complex control devices for calibration and control. Through a physically balanced design, it naturally maintains balance based on the center of gravity even when rotation or tilting occurs.

[0147] * Reduction in production and operating costs

[0148] Because electronic gimbals utilize precision electronics, motors, and batteries, they are more expensive than mechanical gimbals, and repairs and replacements are also costly. Furthermore, due to the high number of electronic components, repairs are complex and time-consuming in the event of a breakdown, and they are vulnerable to environmental factors such as moisture and dust.

[0149] The 2-axis mechanical gimbal of the present invention has no expensive electronic components such as batteries or motors and has a simple structure, making the manufacturing cost very low, and maintenance costs are also low due to the simple mechanical structure.
