[0051] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0052] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons of ordinary skill in the art to which the invention belongs.

Terms such as "upper", "lower", "left", and "right" are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0053] The anchor winch system is installed on a vessel and includes the anchor winch and hydraulic system. For example, it includes the main pump station, servo pump station, engine room control unit, and solenoid valves in the bow compartment; the anchor winch actuator, chain stopper actuator, and engine side console located on the bow deck; and sensors that collect information about the anchor winch status, including but not limited to sensors for the chain stopper pin, chain stopper blade, clutch handle, motor handle, brake disc, anchor chain speed, and anchor chain length.
[0054] The windlass system has three control modes: on-board control via an onboard system, remote control from the bridge via a ship-side system, and remote control via a shore-based system. The system controls the hydraulic motor, chain stopper, brake, clutch, and other components of the windlass system to complete designated anchor handling operations. The on-board system can be located at the windlass system's control console, the ship-side system in the ship's bridge, and the shore-based system onshore, such as at a dock. Figure 1 This is a flow chart of a control method for an anchor winch system provided by an embodiment of the present disclosure. Figure 1 As shown, the control method includes:
[0055] In step S11, the shore-based system obtains the monitoring data sent by the ship-side system.
[0056] Among them, the monitoring data includes ship environment information and anchor windlass system status information.
[0057] In step S12, it is determined whether the first condition is satisfied.
[0058] The first condition at least includes: a first network delay determined based on monitoring data does not exceed a first preset value. The first network delay is a network delay from the ship-side system to the shore-based system.
[0059] In step S13, when the first condition is met, the shore-based system sends a remote control instruction for controlling the anchor winch system to the ship-side system.
[0060] In step S14, the ship-side system obtains remote control instructions.
[0061] In step S15 , it is determined whether the second condition is satisfied.
[0062] Among them, the second condition at least includes: the second network delay determined based on the remote control instruction does not exceed a second preset value, and the second network delay is the network delay from the shore-based system to the ship-end system.
[0063] In step S16, when the second condition is met, the ship-side system sends a control instruction corresponding to the remote control instruction to the machine-side system.
[0064] Among them, the engine-side system is used to control the operation of the anchor winch system.
[0065] The shore-based system acquires monitoring data sent by the ship-side system. This monitoring data includes information about the vessel's environment and the status of the anchor winch system, enabling the shore-based system to understand operational status. Based on the acquired monitoring data, a first network delay is determined, thereby obtaining the network delay from the ship-side system to the shore-based system. When the first network delay does not exceed a first preset value, the shore-based system sends a remote control command to the ship-side system, which then receives the remote control command. Before the anchor winch system operates, the ship-side system determines a second network delay based on the remote control command, thereby obtaining the network delay from the shore-based system to the ship-side system. Only when the second network delay does not exceed a second preset value does the ship-side system issue a control command corresponding to the remote control command to the on-board system, which then controls the operation of the anchor winch system.
[0066] For large ships, especially ocean-going ships, the environment is complex and changeable. The environment has a great impact on the communication between the shore-based system and the ship-end system, resulting in instability of the communication network between the shore-based system and the ship-end system, large fluctuations, and fluctuating network delays, or even interruptions, which seriously affects the shore-based system's remote control of anchoring operations. In the disclosed embodiment, by determining the network delay from the ship-end system to the shore-based system and the network delay from the shore-based system to the ship-end system during the transmission of monitoring data and remote control instructions between the shore-based system and the ship-end system, it is ensured that when performing anchoring operations, the network delay between the shore-based system and the ship-end system is within a safe range, thereby avoiding errors in anchoring operations, improving the reliability and stability of the anchor windlass system control, and ensuring the safety of the ship.
[0067] Figure 2 This is a flow chart of a control method for an anchor winch system provided by an embodiment of the present disclosure. Figure 2 As shown, the method includes:
[0068] In step S21, the ship-side system periodically sends monitoring data to the shore-based system.
[0069] The monitoring data includes ship environment information and anchor winch system status information.
[0070] Vessel environmental information includes, but is not limited to, the vessel's location, water depth, speed, and wind, wave, and current information. This information reflects the external environment, ensuring that the vessel is within the designated anchorage area, that the vessel's speed through the water is below a predetermined maximum speed (e.g., less than 1.5 knots), and that wind, current, and surge conditions are below predetermined values, ensuring the external environment is suitable for anchoring operations.
[0071] The anchor winch system status information includes, but is not limited to, the anchor winch status information and the anchor winch pump station status information in the anchor winch system. For example, the anchor winch status information includes, but is not limited to, the status of the chain stopper, the status of the clutch, the status of the brake, the length of the anchor chain paid out, the height position of the anchor lip, and the speed of the anchor chain. The anchor winch status information can reflect the current working status of the anchor winch to ensure that the state of the anchor winch is suitable for executing the current operating instructions. The anchor winch pump station status information includes, but is not limited to, the particle size, temperature, liquid level, pump station pressure of the hydraulic oil in the hydraulic system, and the current in the electronic control system. The anchor winch pump station status information can reflect the health status of the anchor winch pump station to ensure that the anchor winch pump station has no faults and is suitable for controlling the anchor winch to operate.
[0072] The periodicity at which the ship-side system sends monitoring data to the shore-based system can vary in different situations. For example, during remote control, the ship-side system may send monitoring data to the shore-based system every 5 seconds; during machine-side control or bridge remote control, the ship-side system may send monitoring data to the shore-based system every 5 minutes.
[0073] During non-remote control, i.e., on-board or remote control from the bridge, longer intervals for sending monitoring data to shore-based systems can reduce energy consumption and allow the shore-based system to understand the vessel's status. During remote control, shorter intervals for sending monitoring data can improve remote control accuracy.
[0074] In step S22, the shore-based system obtains the monitoring data sent by the ship-side system.
[0075] During the execution of the entire method, the shore-based system can continuously receive monitoring data sent by the ship-side system.
[0076] In step S23, the shore-based system determines the first network delay based on the current time when the monitoring data is acquired and the timestamp of the monitoring data.
[0077] The monitoring data sent by the ship-end system also includes the timestamp of the sending time. The shore-based system can determine the first network delay, that is, the network delay from the ship-end system to the shore-based system, by comparing the current time when the monitoring data is obtained with the timestamp of the monitoring data.
[0078] Since the ship-side system periodically sends monitoring data to the shore-based system, and the shore-based system also continuously receives the monitoring data sent by the ship-side system, each time the monitoring data is received, the first network delay can be determined, thereby determining the network fluctuation from the ship-side system to the shore-based system, ensuring that the network delay remains within a safe range during the entire anchoring operation, avoiding anchoring operation errors, improving the reliability and stability of the anchor windlass system control, and ensuring the safety of the ship.
[0079] In step S24 , the first network delay is compared with a first preset value.
[0080] The first network delay is compared with a first preset value to ensure that the network delay remains within a safe range. Subsequent steps are allowed only when the network delay remains within the safe range. If the first network delay exceeds the first preset value, it indicates that the network delay exceeds the safe range and remote control via the shore-based system is not appropriate.
[0081] Exemplarily, the first preset value may be 5s to 30s.
[0082] In step S25, the shore-based system determines the vessel environment and the state of the anchor winch system based on the acquired monitoring data.
[0083] As previously mentioned, the monitoring data includes vessel environmental information and anchor winch system status information. The vessel environmental information includes information related to the vessel's external environment, while the anchor winch system status information includes information reflecting the anchor winch's operating status and the health of the anchor winch pump station. Therefore, the shore-based system can determine the vessel's environment and anchor winch system status based on the acquired shore-based system information.
[0084] Step S25 may be performed before step S23 or after step S23 or after step S24.
[0085] In step S26 , it is determined whether the first condition is satisfied.
[0086] The first condition includes: a first network delay determined based on monitoring data does not exceed a first preset value, and the ship environment and the anchor windlass system status both meet the remote control requirements of the anchor windlass system.
[0087] To ensure the reliability and stability of anchor winch system control, low network latency is required. Furthermore, anchoring operations have certain requirements for the vessel environment. Anchoring operations are difficult in unsuitable vessel environments, and the status of the anchor winch system can also affect anchoring operations. Anchoring operations performed in a more suitable vessel environment and anchor winch system status can ensure safe, reliable, and stable anchoring operations.
[0088] If the first condition is met, that is, the first network delay does not exceed the first preset value, and the vessel environment and the anchor winch system status both meet the requirements for remote control of the anchor winch system, the subsequent step S27 is executed. If the first condition is not met, it indicates that the conditions for switching to the third control mode are not met, and remote control via the shore-based system is not appropriate. Anchoring operations can only be performed via the first or second control mode, so the process can be terminated. In addition, a prompt message can be output to inform the staff that the shore-based system cannot remotely control the steering gear system, such as a prompt sound or a prompt screen.
[0089] In step S27, the shore-based system sends a remote control instruction for controlling the anchor winch system to the ship-side system.
[0090] There may be various remote control commands for different anchoring operations, such as commands for controlling the windlass system to prepare the anchor, commands for controlling the windlass system to drop the anchor, commands for controlling the windlass system to drop the anchor, or commands for controlling the windlass system to collect the anchor.
[0091] In step S28, the ship-side system obtains the remote control instruction.
[0092] In step S29, the ship-side system determines the second network delay based on the current time of acquiring the remote control instruction and the timestamp of the remote control instruction.
[0093] The remote control instructions sent by the shore-based system include a timestamp of the sending time. The ship-side system can determine the second network delay, that is, the network delay from the shore-based system to the ship-side system, by comparing the current time when the remote control instruction is obtained with the timestamp of the remote control instruction.
[0094] In step S30 , the second network delay is compared with a second preset value.
[0095] The second network delay is compared with a second preset value to ensure that the network delay remains within a safe range. Subsequent steps are allowed only when the network delay remains within the safe range. If the second network delay exceeds the second preset value, it indicates that the network delay exceeds the safe range and remote control via the shore-based system is not appropriate.
[0096] For example, the second preset value may be 5s to 30s. The second preset value may be the same as or different from the first preset value.
[0097] In step S31, the ship-side system obtains current anchor windlass system status information and determines the current anchor windlass system status.
[0098] The anchor windlass system status information includes information reflecting the working status of the anchor windlass system. The current anchor windlass system status information is obtained through the ship-side system to reconfirm the status of the chain stopper, the status of the clutch, the status of the brake, the length of the anchor chain, the height position of the anchor lip, and the speed of the anchor chain in the anchor windlass system, so as to determine the working status of the anchor windlass system.
[0099] In step S32, it is determined whether the state of the anchor winch system meets the execution requirement of the anchor winch operation corresponding to the remote control instruction.
[0100] The anchoring operations that can be performed vary depending on the working state of the anchor winch system.
[0101] For example, it may be an instruction for controlling the anchor windlass system to prepare the anchor, or an instruction for controlling the anchor windlass system to drop the anchor, or an instruction for controlling the anchor windlass system to drop the anchor, or an instruction for controlling the anchor windlass system to collect the anchor.
[0102] Anchoring operations include preparing anchor, dropping anchor, casting anchor and collecting anchor. When preparing anchor, the anchor windlass system needs to be in the following working state: the main pump is running, the servo pump is running, the clutch is closed, the brake is opened, the chain stopper is opened, the chain stopper pin is pulled out, and the length of the anchor chain is less than the height from the anchor lip to the water surface.
[0103] When dropping anchor, the working state of the windlass system needs to be that the main pump is running, the servo pump is running, the clutch is fully opened, the brake is fully closed, the chain stopper is fully opened, and the chain stopper pin is fully pulled out.
[0104] When collecting anchor, the working state of the anchor windlass system needs to be that the main pump is running, the servo pump is running, the clutch is closed, the brake is opened, the chain stopper is opened, the chain stopper pin is pulled out, and the anchor chain is released less than the depth from the anchor lip to the seabed.
[0105] Step S32 may be performed before step S30 , or after step S30 or after step S31 .
[0106] In step S33, it is determined whether the second condition is satisfied.
[0107] The second condition includes: a second network delay determined based on the remote control instruction does not exceed a second preset value, and a state of the anchor winch system meets an execution requirement of an anchor winch operation corresponding to the remote control instruction.
[0108] To ensure the reliability and stability of the windlass system control, low network latency is required. Furthermore, during anchoring operations, the windlass system must be in a state that allows it to execute the corresponding remote control commands, such as arming the anchor, dropping the anchor, casting the anchor, or reeling in the anchor.
[0109] If the second condition is met, that is, the second network delay does not exceed the second preset value, and the anchor winch system status meets the execution requirements for the anchor winch operation corresponding to the remote control instruction, the subsequent step S33 is executed. If the second condition is not met, it indicates that the conditions for switching to the third control mode are not met, remote control via the shore-based system is not suitable, and anchoring operations can only be carried out via the first control mode or the second control mode, or the anchor winch operation corresponding to the remote control instruction is not suitable, so the process can be terminated. In addition, a prompt message can be output to inform the staff that the shore-based system cannot remotely control the steering gear system or that the anchor winch operation corresponding to the remote control instruction cannot be executed, such as a prompt sound or prompt screen.
[0110] In step S34, the ship-side system sends a control instruction corresponding to the remote control instruction to the machine-side system.
[0111] That is, the ship-side system sends a control instruction to the engine-side system based on the received remote control instruction, and the engine-side system controls the operation of the anchor windlass system.
[0112] In step S35, after receiving the control instruction from the ship-side system, the engine-side system obtains the current state information of the anchor windlass system and determines the current state of the anchor windlass system.
[0113] The engine-side system obtains the current anchor windlass system status information again, and confirms the current anchor windlass system status again to ensure that the anchor windlass system status meets the execution requirements of the anchor windlass operation corresponding to the remote control instruction, so that the anchor windlass system can complete the corresponding operation normally.
[0114] In step S36, when the anchor windlass system state determined by the engine-side system meets the execution requirement of the anchor windlass operation corresponding to the remote control instruction, the anchor windlass operation corresponding to the remote control instruction is executed.
[0115] By determining the status of the anchor windlass system and ensuring that the anchor windlass system can complete the corresponding operations normally, the anchor windlass system is controlled to execute the anchor windlass operations indicated by the remote control instructions to complete the anchoring operation.
[0116] When the state of the windlass system determined by the engine-side system does not meet the execution requirement of the windlass operation corresponding to the remote control instruction, the windlass system is not controlled to perform the corresponding windlass operation.
[0117] The remote control command may be a command to prepare anchor, release anchor, cast anchor or collect anchor, thereby realizing one-key control through the remote control command, completing one-key anchor preparation, one-key anchor release, one-key anchor casting or one-key anchor collection.
[0118] Figure 3 Schematic diagram of the structure of a control device of an anchor winch system provided by an embodiment of the present disclosure. Figure 3As shown, the control device includes a shore-based system 41, a ship-side system 42 and an aircraft-side system 43. The shore-based system 41, the ship-side system 42 and the aircraft-side system 43 can be used to jointly execute Figure 1 or Figure 2 The control method shown.
[0119] The shore-based system 41 is used to obtain the monitoring data sent by the ship-end system 42 and determine whether the first condition is met, and when the first condition is met, send a remote control instruction for controlling the anchor windlass system to the ship-end system 42.
[0120] The monitoring data includes vessel environment information and anchor winch system status information. The first condition includes at least: a first network delay determined based on the monitoring data does not exceed a first preset value. The first network delay is the network delay from the ship-side system 42 to the shore-based system 41;
[0121] The ship-side system 42 is used to obtain the remote control instruction and determine whether the second condition is met, and when the second condition is met, send a control instruction corresponding to the remote control instruction to the machine-side system 43.
[0122] The second condition at least includes: a second network delay determined based on the remote control instruction does not exceed a second preset value. The second network delay is the network delay from the shore-based system 41 to the ship-side system 42.
[0123] The machine-side system 43 is used to control the operation of the windlass system.
[0124] The shore-based system acquires monitoring data sent by the ship-side system. This monitoring data includes information about the vessel's environment and the status of the anchor winch system, enabling the shore-based system to understand operational status. Based on the acquired monitoring data, a first network delay is determined, thereby obtaining the network delay from the ship-side system to the shore-based system. When the first network delay does not exceed a first preset value, the shore-based system sends a remote control command to the ship-side system, which then receives the remote control command. Before the anchor winch system operates, the ship-side system determines a second network delay based on the remote control command, thereby obtaining the network delay from the shore-based system to the ship-side system. Only when the second network delay does not exceed a second preset value does the ship-side system issue a control command corresponding to the remote control command to the on-board system, which then controls the operation of the anchor winch system.
[0125] For large ships, especially ocean-going ships, the environment is complex and changeable. The environment has a great impact on the communication between the shore-based system and the ship-end system, resulting in instability of the communication network between the shore-based system and the ship-end system, large fluctuations, and fluctuating network delays, or even interruptions, which seriously affects the shore-based system's remote control of anchoring operations. In the disclosed embodiment, by determining the network delay from the ship-end system to the shore-based system and the network delay from the shore-based system to the ship-end system during the transmission of monitoring data and remote control instructions between the shore-based system and the ship-end system, it is ensured that when performing anchoring operations, the network delay between the shore-based system and the ship-end system is within a safe range, thereby avoiding errors in anchoring operations, improving the reliability and stability of the anchor windlass system control, and ensuring the safety of the ship.
[0126] Optionally, the shore-based system 41 is further configured to determine a first network delay based on the current time when the monitoring data is acquired and the timestamp of the monitoring data, and compare the first network delay with a first preset value. That is, the shore-based system 41 is further configured to execute the aforementioned steps S23 and S24.
[0127] Optionally, the first condition also includes: the vessel environment and the anchor winch system status both meet the requirements for remote control of the anchor winch system. The shore-based system 41 is further configured to determine the vessel environment and the anchor winch system status based on the acquired monitoring data; and to determine whether the vessel environment and the anchor winch system status meet the requirements for remote control of the anchor winch system. In other words, the shore-based system 41 is further configured to execute the aforementioned steps S25 and S26.
[0128] Optionally, the ship-side system 42 is further configured to determine a second network delay based on the current time of acquiring the remote control command and the timestamp of the remote control command, and compare the second network delay with a second preset value. That is, the ship-side system 42 is further configured to execute the aforementioned steps S28 and S29.
[0129] Optionally, the second condition also includes: the anchor winch system status meets the execution requirements of the anchor winch operation corresponding to the remote control command. The ship-side system 42 is further configured to obtain current anchor winch system status information, determine the current anchor winch system status, and determine whether the anchor winch system status meets the execution requirements of the anchor winch operation corresponding to the remote control command. In other words, the ship-side system 42 is further configured to execute the aforementioned steps S31 and S32.
[0130] The engine-side system 43 is further configured to, upon receiving a control command from the ship-side system 42, obtain current anchor windlass system status information and determine the current anchor windlass system status. If the anchor windlass system status satisfies the execution requirements of the anchor windlass operation corresponding to the remote control command, the engine-side system 43 executes the anchor windlass operation corresponding to the remote control command. In other words, the engine-side system 43 is further configured to execute steps S35 and S36 described above.
