Description

Technical Field

[0001] The present application relates to the technical field of ship berths, and in particular to a method and device for adaptively belting a berth at a dock. Background Art

[0002] In the shipping industry, berthing a ship at a dock is a critical and complex operation process that requires a high degree of precision, coordination and safety. The traditional way of berthing a ship mainly relies on the manual operation of the sailors on board and the ship's own power system. When the ship approaches the dock, the sailors on board first need to use a cable gun or throw it manually to accurately pass one end of the cable to the staff on the dock. This process requires the sailors to have good force control, sense of direction and accuracy, because the transfer of the cable is not only related to the smooth progress of the subsequent berthing, but also directly affects the safety of the dock staff. Once the cable is successfully transferred, the dock staff will quickly fix it on the mooring pile to provide initial fixing force for the ship.

[0003] Next, the ship's driver needs to operate the ship's propeller and steering rudder to finely adjust the ship's position and attitude according to the location of the dock, the size of the waves, the direction of the wind, and the ship's own dynamic characteristics. This process often requires multiple attempts and adjustments, because natural factors such as waves and wind will continue to change and interfere with the ship's berthing. At the same time, the driver's professional level and experience also directly affect the efficiency and safety of berthing. As the ship gradually approaches the dock, the ship's staff need to work closely together to wrap and fix the cable to the ship's mooring pile. This step also requires a high degree of coordination and accuracy, because the way the cable is fixed directly affects the stability and safety of the ship at the dock.

[0004] However, there are many challenges in the traditional way of berthing ships. Especially in rough weather, the violent surge of waves and the strong effect of wind will greatly increase the difficulty and risk of berthing. The swaying and drifting of ships in the wind and waves make the berthing process more difficult to control, and put higher requirements on the sailors' operating skills and psychological quality. At the same time, the safety of operators will also be threatened, because they are easily impacted by waves and blown by wind when working on the deck, and there is a risk of falling and injury. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0055] The analysis method involved in the embodiments of the present application can be implemented by a terminal device or a server, and the present application does not impose any special restrictions on this. For the convenience of understanding and description, the following embodiments are described in detail by taking a server as an example.

[0056] It should be noted that the server may be a single device or a system consisting of multiple devices, that is, a distributed server, and this application does not make any specific limitation on this.

[0057] like Figure 1 As shown, a method for adaptively cable-carrying a berth provided in an embodiment of the present application includes:

[0058] 101. Obtain the ship size, relative position of the ship and the pier, and the distance between the ship and the pier of the ship to be berthed, so as to adjust the distance between two mooring piles on the berthing pier according to the ship size.

[0059] Specifically, in one embodiment of the present application, obtaining the ship size, the relative position of the ship and the dock, and the distance between the ship and the dock of the ship to be berthed specifically includes:

[0060] A detection device is installed at the berthing wharf, and the berthing ship is monitored in real time by the detection device to obtain the ship size corresponding to the berthing ship;

[0061] The ship position of the ship to be berthed during the berthing process is obtained in real time, so as to determine the relative position of the ship terminal between the berthing terminal and the ship to be berthed, as well as the corresponding ship terminal distance based on the position information of the berthing terminal and the ship position.

[0062] In one embodiment, an advanced laser scanning detection device is installed at a suitable location of the berthing terminal. The device can emit a laser beam and receive the reflected signal, and accurately measure the external dimensions of the ship to be berthed by processing these signals, including key parameters such as the length, width and height of the ship. When the ship to be berthed approaches the terminal, the laser scanning detection device automatically starts to scan the ship in all directions. The scanning data is transmitted to the central processing unit of the system in real time, and the size information of the ship is quickly and accurately calculated through algorithm processing.

[0063] Multiple GPS receivers and radar sensors are also installed at the berthing terminal to obtain the location information of the ship to be berthed in real time. These devices can continuously track the movement trajectory of the ship to ensure the accuracy and real-time nature of the location data. At the same time, the system pre-stores the precise location information of the berthing terminal, including the latitude and longitude coordinates, orientation, etc. of the terminal. When the ship approaches the terminal, the system determines the relative position between the ship and the terminal, including the direction angle and distance of the ship relative to the terminal, based on the real-time location information of the ship and the location information of the terminal, by calculating the geometric relationship. Specifically, the system calculates the vector difference between the ship's position and the terminal's position to obtain the ship-to-terminal spacing, that is, the straight-line distance from the ship's current position to the designated berthing point at the terminal. At the same time, by analyzing the angle between the ship's moving direction and the terminal's orientation, the offset angle of the ship relative to the terminal is determined.

[0064] The acquired data such as ship size, relative position and spacing between the ship and the dock are transmitted to the control box of the system in real time. Based on these data, the algorithm in the control box dynamically adjusts the spacing between the two mooring piles on the berthing dock to ensure that the mooring piles can adapt to ships of different sizes. At the same time, when the distance between the ship and the dock is less than the preset berth spacing, the system automatically controls the cable gun to throw the two cables of the ship to the berthing dock according to the relative position of the ship and the dock. During this process, the system continuously monitors the position changes of the ship to ensure that the cables can be thrown accurately to the specified position.

[0065] In one embodiment of the present application, adjusting the distance between two mooring piles on the berthing pier according to the size of the ship specifically includes:

[0066] A control box is arranged on the berthing wharf, and two movable winches are arranged within the designated position of the berthing wharf; wherein the movable winches are provided with a winch, a fixing device for fixing the cable is arranged on the winch, and a cable bollard is arranged at a position opposite to the winch;

[0067] The ship size is input into the control box so that the movable winch is controlled by the control box to adjust the distance between two mooring bollards on the berthing pier according to the ship size so that the mooring bollard spacing matches the ship size.

[0068] In one embodiment, an intelligent control box is installed on the berthing terminal as the core processing unit of the system. The control box is equipped with advanced control algorithms and communication modules, which can receive and process data from various sensors and issue control instructions. Two movable winches are set within the specified position range of the berthing terminal. The two winches are flexibly designed and can move along tracks or specified paths on the dock to accommodate ships of different sizes. Each movable winch is equipped with a capstan, which is provided with a device for fixing the cable, such as a cable clamp or a cable hook. A cable pile is set at a position opposite to the capstan to provide a stable support point when the winch reels in the cable.

[0069] When the ship to be berthed approaches the dock, the ship's size information, including the length and width of the ship, is obtained through a laser scanning detection device or other measurement means. The obtained ship size information is input into the control box. The algorithm in the control box calculates the ideal spacing between the two mooring bollards based on the size of the ship to ensure that the mooring bollards can adapt to the size of the ship and provide stable support for the mooring bollards. The control box issues a control command to drive the two movable winches to move along the track or specified path, adjusting the distance between them so that the spacing between the mooring bollards matches the size of the ship. During this process, the control box continuously monitors the position of the winch to ensure accurate adjustment of the spacing between the mooring bollards.

[0070] When the spacing between the bollards is adjusted, the crew or the automated system throws the ship's cable near the bollards at the berthing pier. The crew or the automated system fixes the cable to the cable fixing device of the winch and starts the winch of the movable winch to automatically reel in the cable. During the process of reeling in the cable, the control box can fine-tune the rotation speed and direction of the winch according to the real-time position and offset of the ship to ensure that the ship can dock smoothly and accurately at the designated location.

[0071] 102. When the distance between the ship and the dock is less than the preset berth distance, the cable-throwing gun is controlled to throw the two cables of the ship to be berthed to the berthing dock according to the relative position of the ship and the dock.

[0072] Specifically, in one embodiment of the present application, when the distance between the ship and the dock is less than the preset berth distance, according to the relative position of the ship and the dock, controlling the cable-throwing gun to throw two cables of the ship to be berthed to the berthing dock specifically includes:

[0073] Compare the real-time calculated ship-to-berth spacing with the preset berth spacing;

[0074] When the comparison result shows that the distance between the ship and the berth is less than the preset berth distance, the target direction and target distance of the berth relative to the ship to be berthed are determined according to the relative position of the ship and the berth;

[0075] Generate control instructions for the ship to be berthed through the control box according to the direction and distance, and send the control instructions to the ship to be berthed;

[0076] According to the control instructions, the ship to be berthed is controlled to throw the cable gun to the target direction of the berthing terminal and the target distance, so that the two cables of the ship to be berthed are thrown to the berthing terminal.

[0077] In one embodiment, a ship position monitoring system is installed at the berthing terminal. The system can obtain the position information of the ship to be berthed in real time, and calculate the ship-berth distance, that is, the straight-line distance from the current position of the ship to the designated berthing point of the terminal, in combination with the known position information of the berthing terminal. At the same time, the system presets a berth distance threshold in the control box as a basis for judging whether the ship is close enough to the terminal for cable-dropping operation. The system compares the ship-berth distance calculated in real time with the preset berth distance to judge whether the ship has entered the range suitable for cable-dropping.

[0078] When the comparison result shows that the distance between the ship and the dock is less than the preset berth distance, the system determines the target direction and target distance of the berthing dock relative to the ship to be berthed based on the relative position of the ship and the dock, that is, the direction angle and distance difference between the current position of the ship and the designated berthing point of the dock. The target direction refers to the direction in which the cable gun needs to point to ensure that the cable can be thrown accurately to the designated position on the dock. The target distance refers to the length of cable or the throwing force that the cable gun needs to throw to adapt to the actual distance between the ship and the dock.

[0079] The control box generates control instructions for the ship to be berthed based on the determined target direction and target distance. These instructions include parameters such as the direction adjustment angle of the cable-cutting gun, the throwing force or the throwing time. The system sends the control instructions to the cable-cutting control system on the ship to be berthed through wireless communication. After receiving the instructions, the system can automatically or manually perform the cable-cutting operation.

[0080] The crew or automated system on the berthing vessel adjusts the direction and throwing force of the cable gun according to the control instructions received. At the right time, the crew or automated system triggers the cable gun to throw the two cables to the target direction of the berthing terminal and to the target distance. After the cables are thrown to the terminal, the staff or automated equipment on the terminal will fix the cables on the cable bollards to prepare for the subsequent berthing operation.

[0081] 103. When two cables are fixed to the winch of the movable winch corresponding to the cable pile of the berthing terminal, the movable winch is triggered to automatically retract the two cables, and the offset angle and offset distance of the ship to be berthed are determined based on the relative position between the real-time position of the ship and the berthing terminal.

[0082] Specifically, in one embodiment of the present application, when two cables are fixed to the winch of the movable winch corresponding to the cable pile of the berthing terminal, triggering the movable winch to automatically retract the two cables specifically includes:

[0083] A track and a movable base that can move along the track are set on the berthing pier, and a movable winch and a bollard are installed on the movable base;

[0084] Wind the two cables from the outside of the corresponding cable bollards to the winches of the corresponding movable winches, and fix them to the corresponding winches;

[0085] When two cables are fixed to the winches of the movable winches, the two movable winches are triggered to start, so as to automatically collect the two cables based on the mobile base, so that the vessel to be berthed moves toward the berthing pier.

[0086] In one embodiment, one or more tracks are provided on the berthing pier, and these tracks extend along the length or width direction of the pier to provide a path for the movement of the mobile base. The mobile base is designed with rollers or slide rails matching the tracks, and can move smoothly and accurately along the tracks. A driving device, such as a motor or a hydraulic cylinder, is installed on the mobile base to provide movement power.

[0087] Two movable winches are installed on the mobile base, each of which is equipped with a winch and a winch drive. The winch is used to wind and collect the cable, and the winch drive provides the power for the winch to rotate. Next to each movable winch, a corresponding bollard is installed. The bollard is used to provide additional support and fixing points when the winch collects the cable, ensuring the stability and safety of the cable.

[0088] Wind the two cables from the outside of the corresponding bollard to the winch of the corresponding movable winch. When winding, ensure that the cables are evenly distributed on the winch to avoid overlapping or crossing. Secure the ends of the cables to the fixings on the winch, such as cable clamps, bolts or locks. Ensure that the fixing is firm and reliable to prevent the cables from falling off or slipping during the retrieval process.

[0089] When both cables are fixed to the winches of the movable winches, the two movable winches are triggered to start. The start signal can be sent through the control box, or it can be operated by a remote control or a manual switch. After the movable winch is started, the winch drive device starts to rotate the winch and automatically retract the cable. At the same time, the mobile base moves along the track according to the retracting speed and direction of the winch to keep the relative position between the winch and the ship stable. During the retracting process of the cable, the movable winch and the mobile base work together to gradually move the berthing ship to be berthed toward the berthing terminal. By controlling the retracting speed of the winch and the moving speed of the mobile base, the moving distance and direction of the ship can be accurately controlled.

[0090] In one embodiment of the present application, based on the relative position between the real-time position of the ship and the berthing terminal, determining the offset angle and offset distance of the ship to be berthed specifically includes:

[0091] During the process of collecting the two cables, the detection device installed on the berthing dock is used to monitor the berthing ship in real time, and obtain the ship position of the berthing ship in real time to determine the relative position of the ship and the dock at the current moment;

[0092] Based on the relative position of the ship and the pier at the current moment, the offset angle of the berthing pier relative to the ship to be berthed and the offset distance at the offset angle are determined.

[0093] In one embodiment, a set of advanced detection devices, such as radar, LiDAR or GPS receivers, are installed at the berthing terminal to monitor the berthing ship in real time. The detection device can continuously and accurately obtain the position information of the berthing ship, including the longitude, latitude, heading and speed of the ship. This information is transmitted to the control box or central processing unit in real time via a data line or wireless network.

[0094] After the control box or central processing unit receives the ship position information from the detection device, it combines the known position information of the berthing terminal to calculate the relative position of the ship to the terminal at the current moment in real time. The relative position of the ship to the terminal includes the direction angle and distance of the ship relative to the terminal. The direction angle indicates the angle between the ship's heading and the direction of the terminal, and the distance indicates the straight-line distance from the current position of the ship to the designated berthing point of the terminal.

[0095] Based on the relative position of the ship to the dock at the current moment, the system further calculates the offset angle of the berthing dock relative to the ship to be berthed. The offset angle is the direction that the ship needs to adjust to ensure that the ship can berth along the correct path. At the same time, the system also calculates the offset distance at the offset angle. The offset distance is the distance the ship needs to move to reach the specified berthing position. The offset distance can be dynamically adjusted based on factors such as the size of the ship, speed, and layout of the berthing dock.

[0096] The system sends the calculated offset angle and offset distance to the navigation cabin or automation system of the ship to be berthed through control commands. The crew or automation system adjusts the ship's course and speed according to the received control commands, so that the ship moves along the offset angle and offset distance. During the movement, the detection device continues to monitor the ship in real time and updates the ship's position information in real time. The system dynamically adjusts the control commands according to the updated ship's position information to ensure that the ship can dock accurately and smoothly at the designated location.

[0097] In one embodiment of the present application, after triggering the movable winch to automatically retract the two cables, the method further includes:

[0098] A cable detection device is provided on the movable winch;

[0099] When the ship to be berthed approaches the berthing wharf, the cable data of the two cables are obtained in real time through the cable detection device; wherein the cable data includes cable tension and cable direction;

[0100] According to the cable data and the current distance between the ships and docks, the cable tension is adjusted, and according to the adjusted cable tension, the two cables are controlled to move in the cable direction.

[0101] In one embodiment, an advanced cable detection device is installed on each movable winch. This device can monitor the tension and direction of the cable in real time, and provide accurate data support for cable control during the berthing process. When the ship to be berthed approaches the berthing terminal, the cable detection device continues to work and obtains the cable data of the two cables in real time. The cable data includes the tension of the cable, that is, the tension on the cable, and the direction of the cable, that is, the direction of the cable relative to the winch or the ship.

[0102] The system adjusts the cable tension based on the cable data obtained in real time and the distance between the ship and the dock at the current moment. If the cable tension is too large, the system may instruct the movable winch to loosen the cable appropriately to reduce the tension and avoid damage to the cable or ship structure. If the cable tension is too small, the system will instruct the winch to tighten the cable to ensure that the ship can stably approach the dock.

[0103] While adjusting the cable tension, the system also controls the two cables to move in the corresponding direction according to the cable direction data. If the cable direction deviates from the predetermined berthing path, the system will correct the direction of the cable by adjusting the rotation direction or speed of the winch, so that the ship can berth along the correct path.

[0104] In one embodiment of the present application, the cable tension is adjusted according to the cable data and in combination with the distance between the ship and the dock at the current moment, specifically including:

[0105] According to the current ship-pier distance, determine the target cable tension value corresponding to the ship-pier distance;

[0106] The real-time cable tension obtained in real time is compared with the target cable tension value. If the real-time cable tension is less than the target cable tension value, a corresponding first tension difference is determined, and the corresponding movable winch is controlled to increase the first tension difference until the target cable tension value is reached;

[0107] If the real-time cable tension is greater than the target cable tension value, a corresponding second tension difference is determined, and the corresponding movable winch is controlled to reduce the second tension difference so that the cable tension is within a preset range.

[0108] In one embodiment, the system determines the target cable tension value corresponding to the current ship-pier distance, combined with the type, size, load and characteristics of the berthing pier (such as water depth, tide, wind current, etc.) of the ship through a preset algorithm or table lookup method. The target cable tension value is an ideal tension value to ensure that the ship can be stably berthed, which is neither too large to cause damage to the cable or ship structure, nor too small to cause the ship to lose control or deviate from the berthing path.

[0109] During the berthing process, the system obtains the real-time cable tension of the two cables through the cable detection device installed on the movable winch. The system compares the real-time cable tension with the target cable tension value to determine whether the real-time cable tension is within the ideal range.

[0110] If the real-time cable tension is less than the target cable tension value, the system calculates the corresponding first tension difference, that is, the difference between the target cable tension value and the real-time cable tension. The system controls the corresponding movable winch to increase the tension by tightening the cable until the real-time cable tension reaches the target cable tension value. If the real-time cable tension is greater than the target cable tension value, the system calculates the corresponding second tension difference, that is, the difference between the real-time cable tension and the target cable tension value. The system controls the corresponding movable winch to reduce the tension by loosening the cable to reduce the tension so that the cable tension returns to the preset range.

[0111] During the entire berthing process, the system continuously monitors the real-time cable tension and dynamically adjusts the target cable tension value according to the changes in the distance between the ship and the dock and the influence of external environmental factors. The system adopts a feedback control mechanism to adjust the tension output of the movable winch in real time based on the comparison results of the real-time cable tension and the target cable tension value to ensure that the cable tension is always kept within the ideal range.

[0112] 104. According to the offset distance, the target movable winch corresponding to the offset angle is controlled to rotate so as to dock the ship to be berthed at a designated position of the berthing terminal.

[0113] Specifically, in one embodiment of the present application, according to the offset distance, the target movable winch corresponding to the offset angle is controlled to rotate so as to dock the ship to be berthed at the designated position of the berthing wharf, specifically including:

[0114] According to the offset angle, the corresponding target movable winch is determined in the two movable winches, and according to the offset distance, the corresponding rotation direction and number of rotations of the target movable winch are determined; wherein the rotation direction includes forward rotation and reverse rotation;

[0115] According to the rotation direction control target, the movable winch can be rotated forward or reversely for a number of circles to adjust the moving position of the ship to be berthed so that the ship to be berthed can be docked at the designated position of the berthing terminal.

[0116] In one embodiment, after the system calculates the offset angle of the berthing terminal relative to the ship to be berthed based on the real-time monitoring data, the system will determine the corresponding target movable winch from the two movable winches based on the offset angle. The positive or negative value of the offset angle determines the selection of the target winch. For example, if the offset angle is positive, it means that the ship needs to move to the right (assuming that the ship's forward direction is the front, the left side is negative, and the right side is positive), then the movable winch on the right side is selected as the target winch; conversely, if the offset angle is negative, then the movable winch on the left side is selected.

[0117] According to the calculated offset distance, the system further determines the rotation direction and number of rotations of the target movable winch. The rotation direction is determined by the positive or negative offset distance. If the offset distance is positive, it means that the ship needs to move forward closer to the dock, then the target winch needs to rotate forward to collect the cable and pull the ship closer; if the offset distance is negative (in actual berthing, this usually means that it is necessary to adjust by the action of the winch on the other side or with the ship's own power), it is possible to fine-tune the overall position by adjusting the action of the winch on the other side or combining with the ship's power. Under the logic of this direct control, it can be simplified to not directly achieve this through the reversal of this winch (because reversal is usually used to loosen the cable), but to achieve the purpose by comprehensively controlling the actions of the winches on both sides. However, in the description of this single winch control, we assume that it is adjusted by rotating forward for different numbers of times or in combination with other methods (such as the ship's own power). The number of rotations is calculated based on the specific value of the offset distance and the winding diameter of the winch to ensure that the length of the cable collected or released by the winch matches the offset distance.

[0118] The system sends a control command to the target movable winch according to the determined rotation direction and number of rotations. After receiving the control command, the target movable winch rotates forward or (when necessary, through specific logic coordination) reversely according to the rotation direction and number of rotations required by the command. Through the rotation of the winch, the cable is pulled in or released, thereby adjusting the moving position of the ship to be berthed.

[0119] While the winch is adjusting the ship's position, the system continues to monitor the ship in real time through the detection device and updates the offset angle and offset distance in real time. The system dynamically adjusts the control instructions based on the updated offset angle and offset distance to ensure that the ship can dock accurately and smoothly at the designated position of the berthing terminal.
