[0043] The anchor system is installed on a ship, and the anchor system includes an anchor winch, a hydraulic system, and a control system that controls the anchor winch and the hydraulic system upon receiving a control instruction. The anchor system, for example, includes a main pump station in a bow cabin, a servo pump station, a machine room control unit, and solenoid valves in the hydraulic system; an anchor winch actuator on the bow deck of the ship, a chain stopper actuator, a machine console, and sensor devices that collect the state of the anchor winch, including but not limited to sensors that collect the chain stopper latch, the chain stopper switch, the clutch handle, the motor handle, the brake disc, the chain speed, and the chain length.

[0044] The anchor system has three control modes, namely a first control mode of machine console control through a machine console system, a second control mode of bridge remote control through a ship end system, and a third control mode of remote control through a shore-based system. By controlling the hydraulic motor, the chain stopper, the brake, the clutch, etc. in the anchor system, the specified anchor throwing operation is completed. The machine console system can be located on the console of the anchor system, the ship end system is located in the bridge of the ship, and the shore-based system is located on the shore, such as a wharf. The machine console system, the ship end system, and the shore-based system can all issue anchor system control instructions to control the anchor system to perform anchoring operations.

[0045] Figure 1 is a flowchart of an auxiliary control method of an anchor system provided by an embodiment of the present disclosure. As shown in Figure 1 The auxiliary control method includes the following steps.

[0046] In step S11, an anchor system control instruction is obtained.

[0047] The anchor system control instruction is used to control the anchor system operation.

[0048] In step S12, anchor winch state information is acquired.

[0049] The anchor winch state information is used to reflect the anchor winch state.

[0050] In step S13, it is determined whether the anchor winch state meets the execution requirement of the anchor winch operation corresponding to the anchor winch system control instruction based on the anchor winch state information.

[0051] In step S14, when the anchor winch state does not meet the execution requirement of the anchor winch operation corresponding to the anchor winch system control instruction, the anchor winch system is controlled not to respond to the anchor winch system control instruction.

[0052] By acquiring the anchor winch system control instruction and the anchor winch state information, the anchor winch state information can reflect the anchor winch state, and the anchor winch state can be obtained based on the acquired anchor winch state information, so as to determine whether the anchor winch state meets the execution requirement of the anchor winch operation corresponding to the acquired anchor winch system control instruction, and to ensure that the anchor winch system can smoothly perform the corresponding operation. When the anchor winch state does not meet the execution requirement of the anchor winch operation corresponding to the anchor winch system control instruction, the anchor winch system is controlled not to respond to the anchor winch system control instruction, so as to avoid performing the anchor winch operation that is not suitable for the anchor winch state and causing danger, thereby improving the safety of the mooring operation and ensuring the safety of the ship.

[0053] Figure 2 is a flowchart of an auxiliary control method of an anchor winch system provided by an embodiment of the present disclosure. As shown in the figure, the method comprises: Figure 2

[0054] In step S21, an anchor winch system control instruction is acquired.

[0055] The anchor winch system control instruction can be an instruction issued by any one of the engine room system, the ship end system and the shore-based system. The anchor winch system control instruction is used to control the anchor winch system operation.

[0056] For different mooring operations, the anchor winch system control instruction can be various, for example, it can be an instruction for controlling the anchor winch system to prepare an anchor, or an instruction for controlling the anchor winch system to drop an anchor, or an instruction for controlling the anchor winch system to throw an anchor, or an instruction for controlling the anchor winch system to take up an anchor.

[0057] In step S22, anchor winch system state information is acquired.

[0058] Step S22 comprises acquiring anchor winch state information and acquiring anchor winch pump station state information, wherein the anchor winch state information is used to reflect the anchor winch state, and the anchor winch pump station state information is used to reflect the health state of the anchor winch pump station.

[0059] ​The anchor system state information includes, but is not limited to, anchor state information of the anchor system and anchor pump station state information. The anchor state information includes, but is not limited to, a state of a chain stopper, a state of a clutch, a state of a brake, a length of anchor chain released, a height position of an anchor lip, and a speed of the anchor chain. The anchor state information can reflect a current working state of the anchor, so as to ensure that the anchor is in a state suitable for executing a current operation instruction. The anchor pump station state information includes, but is not limited to, a particle size, a temperature, a liquid level, a pump station pressure, a pump station vibration, and a current in an electric control system of hydraulic oil in a hydraulic system. The anchor pump station state information can reflect a health state of the anchor pump station, so as to ensure that the anchor pump station is free of failure and suitable for controlling the anchor to work.

[0060] In step S23, it is determined whether the anchor state meets an execution requirement of the anchor operation corresponding to the anchor system control instruction based on the anchor system state information.

[0061] In this example, step S23 can include determining whether the anchor state meets an execution requirement of the anchor operation corresponding to the anchor system control instruction based on the anchor state information, and determining whether a health state of the anchor pump station meets an execution requirement of the anchor operation corresponding to the anchor system control instruction based on the anchor pump station state information.

[0062] The anchor state can be determined to meet the execution requirement of the anchor operation corresponding to the anchor system control instruction in the following manner:

[0063] Anchor safety state information corresponding to the anchor system control instruction is obtained. The anchor safety state information is used to reflect a standard state when the anchor system executes the anchor operation corresponding to the anchor system control instruction.

[0064] The anchor state determined based on the anchor state information is compared with the standard state to determine whether the anchor state meets the execution requirement of the anchor operation corresponding to the anchor system control instruction.

[0065] The standard state refers to a state of the anchor when the anchor system can safely execute the anchor operation. The standard state when the anchor system executes the anchor operation corresponding to the anchor system control instruction can be determined by a relevant technical person and stored in the form of data. For example, the safety state information can be stored locally, such as in a ship end system or a machine side system, or can be stored in a cloud server or a shore-based system.

[0066] The standard state of the anchor windlass system during different anchor windlass operations in the mooring operation process can be different, i.e., the anchor windlass safety state information can be different. For example, the mooring operation can include four anchor windlass operations, which are anchor preparation, anchor release, anchor throwing, and anchor taking up. The standard state during anchor preparation is that the working state of the anchor windlass needs to be: the main pump is running, the servo pump is running, the clutch is closed to position, the brake is opened to position, the chain stopper is opened to position, the chain stopper pin is pulled out to position, and the anchor chain length is less than the height from the anchor lip to the water surface.

[0067] The standard state during anchor throwing is that the working state of the anchor windlass needs to be: the main pump is running, the servo pump is running, the clutch is opened to position, the brake is closed to position, the chain stopper is opened to position, and the chain stopper pin is pulled out to position.

[0068] The standard state during anchor taking up is that the working state of the anchor windlass needs to be: the main pump is running, the servo pump is running, the clutch is closed to position, the brake is opened to position, the chain stopper is opened to position, the chain stopper pin is pulled out to position, and the anchor chain length is less than the depth from the anchor lip to the sea bottom.

[0069] In the above steps, by comparing the anchor windlass state determined based on the anchor windlass state information with the standard state of the anchor windlass operation corresponding to the anchor windlass system control instruction executed by the anchor windlass system one by one, when the anchor windlass state determined based on the anchor windlass state information is completely consistent with the standard state of the anchor windlass operation corresponding to the anchor windlass system control instruction executed by the anchor windlass system, it is indicated that the anchor windlass state meets the execution requirement of the anchor windlass operation corresponding to the anchor windlass system control instruction.

[0070] In the present example, the anchor windlass pump station state information includes, but is not limited to, the hydraulic oil particle size, temperature, liquid level, pump station pressure, pump station vibration in the hydraulic system, and current in the electric control system. When determining whether the health state of the anchor windlass pump station meets the execution requirement of the anchor windlass operation corresponding to the anchor windlass system control instruction, the anchor windlass pump station state information can be compared with the standard parameter range of the anchor windlass pump station one by one to determine. The standard parameter range of the anchor windlass pump station refers to the normal range of each item in the anchor windlass pump station state information. For example, the hydraulic oil particle size is usually gradually increased with the accumulation of the running time of the hydraulic pump station, when the hydraulic oil particle size exceeds the normal range, the normal operation of the hydraulic pump station will be affected, the hydraulic oil needs to be filtered to reduce the hydraulic oil particle size, or the hydraulic oil needs to be replaced. When one or more items in the anchor windlass pump station state information are not in the normal range, it is indicated that the health state of the anchor windlass pump station does not meet the execution requirement of the anchor windlass operation corresponding to the anchor windlass system control instruction.

[0071] In step S24, when the anchor windlass system state does not meet the execution requirement of the anchor windlass operation corresponding to the anchor windlass system control instruction, the anchor windlass system is controlled not to respond to the anchor windlass system control instruction.

[0072] That is, in the anchor state and the health state of the anchor pump station, as long as one does not meet the execution requirement of the anchor operation corresponding to the anchor system control instruction, the anchor system is controlled not to respond to the anchor system control instruction.

[0073] In the anchor system, the anchor and the hydraulic system work under the control of the control system, the control system receives the anchor system control instruction issued by the on-board system, the ship end system or the shore-based system, and when the anchor system state does not meet the execution requirement of the anchor operation corresponding to the anchor system control instruction, the control system does not further send the control instruction to the anchor and the hydraulic system, so that the anchor system does not respond to the anchor system control instruction.

[0074] When the anchor system state meets the execution requirement of the anchor operation corresponding to the anchor system control instruction, the control system sends the control instruction to the anchor and the hydraulic system. There are many execution mechanisms in the anchor and the hydraulic system, for example, in the anchor, the execution mechanisms at least include the clutch, the brake, the brake knife and the brake knife bolt, and in the hydraulic system, the execution mechanisms at least include various electromagnetic valves.

[0075] The control system can also implement interlocking control between different execution mechanisms, that is, the anchor state determined by the anchor state information is compared with the standard state, and when the anchor state does not meet the execution requirement of the anchor operation corresponding to the anchor system control instruction, the state of one or several execution mechanisms does not meet the requirement, the control system does not send the control instruction to another or several execution mechanisms, so that the anchor system does not respond to the anchor system control instruction.

[0076] For example, the clutch and the brake implement interlocking control, when the brake is in the loose state, the control system does not send the control instruction to control the clutch to be disengaged; the brake and the brake knife implement interlocking control, when the brake knife is not opened to the position and the bolt is not opened to the position, the control system does not send the control instruction to control the brake to be loose; the brake knife and the anchor chain implement interlocking control, when the anchor chain speed is not 0 and does not exceed the limit value, the control system does not send the control instruction to control the brake knife to be closed; the brake knife bolt and the brake knife implement interlocking control, when the brake knife is not closed to the position, the control system does not send the control instruction to control the bolt to be closed.

[0077] In step S25, based on the anchor state information, the level of the abnormal event is determined.

[0078] In this example, the anchor state information can also be acquired periodically to monitor the anchor system. When it is determined that the anchor state does not meet the execution requirement of the anchor operation corresponding to the anchor system control instruction, it indicates that the anchor system has an abnormality, and based on the items in the anchor state information that do not meet the standard state, the level of the abnormal event is determined to facilitate the staff to make corresponding processing.

[0079] In addition, the anchor winch pump station state information can be periodically acquired, and based on items in the anchor winch pump station state information that exceed a normal range, an abnormal event level is determined, so that a worker can make corresponding processing.

[0080] In step S26, alarm information corresponding to the abnormal event level is issued based on the determined abnormal event level.

[0081] For example, during ship navigation, it is determined that an anchor slip occurs during navigation based on the state of the flashboard of the chain stopper, the state of the brake, and the chain length, and it is determined that the abnormal event level is level one.

[0082] According to the severity of the consequences that can be caused by the abnormality of the anchor winch system, the abnormal event level can be divided into level one, level two, level three, etc. Different abnormal event levels send different alarm information. For example, for the abnormal event level of level two, a whistle and a red light alarm can be sounded in the driver's room and the control room, and for the abnormal event level of level three, a yellow light alarm can be sounded in the control room.

[0083] For some abnormal event levels of level one, in addition to issuing alarm information, an emergency stop control instruction can also be issued to the anchor winch system to control the anchor winch brake to immediately lock, the brake oil cylinder to reverse oil, and the main pump station to stop.
