[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, but not all of the embodiments. Generally, the components of the embodiments of the present application described in the drawings herein can be arranged and designed in various different configurations.

[0053] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is claimed, but rather merely represents selected embodiments of the present application. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without creative effort are intended to fall within the scope of protection of this application. The following embodiments and features therein may be combined with each other unless there is a conflict.

[0054] In the description of this application, it is necessary to explain:

[0055] Relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation and do not necessarily require or imply any actual relationship or order between these entities or operations;

[0056] “Connection” should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0057] See Figure 1 An embodiment of the present application provides a ship propulsion system, which includes a control device group, a propulsion motor group, and a console control unit group.

[0058] The control device group, the propulsion motor group, and the console control unit group have the following connection relationship: the control device group is connected to the propulsion motor group and the console control unit group respectively.

[0059] The functions of the control unit group of the driving console include: receiving driving instructions, processing the driving instructions into sending data, and sending the sending data to the control device group.

[0060] The functions of the control equipment group include: controlling the propulsion motor group according to the data sent by the control unit group of the driving console;

[0061] The function of the propulsion motor group is to provide power for the ship.

[0062] like Figure 2 The ship propulsion system may further include an information collection box. The information collection box may be a stern upper layer collection box, which is arranged at the stern upper layer.

[0063] The information collection box has the following connection relationship: the information collection box is connected to the control device group. The information collection box and the control device group can communicate via the MODBUS-TCP protocol.

[0064] The functions of the information collection box include: collecting hull driving status information.

[0065] The ship driving status information may refer to navigation information.

[0066] The navigation information includes at least one of the following: navigation speed, required speed, navigation destination, driving resistance and energy consumption.

[0067] The hull driving status information may also include alarm information.

[0068] like Figure 3 The propulsion motor group may include a side propulsion motor and two main propulsion motors.

[0069] One side propulsion motor and two main propulsion motors have the following connection relationship: the control device group is connected to the side propulsion motor and the two main propulsion motors respectively.

[0070] The function of the thruster motor is to provide left or right propulsion for the vessel when rotating forward or reverse. For example, when the thruster motor rotates forward, the vessel is propulsed to the left, and when the thruster motor rotates reversely, the vessel is propulsed to the right. Alternatively, when the thruster motor rotates forward, the vessel is propulsed to the right, and when the thruster motor rotates reversely, the vessel is propulsed to the left.

[0071] The function of the main propulsion motor is to provide forward or backward propulsion for the ship when rotating forward or reverse. For example, when the main propulsion motor rotates forward, the ship provides forward propulsion, and when the main propulsion motor rotates reversely, the ship provides backward propulsion.

[0072] The two main propulsion motors can be arranged in a left-right symmetrical form. When the ship moves forward, the left and right main propulsion motors jointly propel the ship.

[0073] Compared with the situation where there is only one main propulsion motor pushing in the middle, two main propulsion motors can better balance the forward movement of the hull.

[0074] like Figure 4 , the control device group may include a main propulsion control device group and a side propulsion control device group.

[0075] The main propulsion control equipment group and the side propulsion control equipment group have the following connection relationship:

[0076] The main propulsion control equipment group is connected to the propulsion motor group and the bridge control unit group respectively;

[0077] The side propulsion control device group is connected to the propulsion motor group and the control unit group on the driving console respectively;

[0078] The main propulsion control equipment group is connected to the two main propulsion motors respectively;

[0079] The side propulsion control device group is connected to the side propulsion motor.

[0080] By dividing the control device group into a main propulsion control device group and a side propulsion control device group, the main propulsion motor and the side propulsion motor can be controlled separately. In a straight-line navigation scenario, when the side propulsion motor is not required, the side propulsion control device group can be put into standby mode to save energy.

[0081] like Figure 5 The main propulsion control equipment group may include a main propulsion MCU, a main propulsion local control box and a main propulsion MCU switch box.

[0082] The main propulsion MCU, main propulsion local control box and main propulsion MCU switch box have the following connection relationship:

[0083] The main propulsion MCU is connected to the main propulsion local control box and the main propulsion MCU switch box respectively;

[0084] The main propulsion local control box is connected to the control unit group on the bridge console and the main propulsion MCU switch box respectively;

[0085] The main propulsion MCU switch box is connected to the two main propulsion motors respectively.

[0086] The main propulsion MCU serves as the core control unit. It processes and outputs control instructions based on sensor data to achieve precise control of the main propulsion motor.

[0087] The main propulsion local control box processes data sent from the control unit group on the bridge into protocol signals and transmits them to the main propulsion MCU and the main propulsion MCU switch box. It also receives signals from sensors such as voltage, current, and temperature, and monitors the main propulsion motor's voltage, current, and temperature in real time to ensure safe operation.

[0088] The functions of the main propulsion MCU switch box include: controlling the power of the main propulsion motor through switching quantities.

[0089] like Figure 6 The side thruster control equipment group can include a side thruster inverter cabinet and a side thruster control box. The side thruster inverter cabinet can be installed in the bow sail and cable compartment of the hull. Its power supply can be provided by a DC switch cabinet. The side thruster inverter cabinet can be equipped with a cooling fan cabinet inside. The cooling fan cabinet can be equipped with a cooling system that automatically activates according to the working conditions to ensure stable operation of the equipment in high temperature environments.

[0090] The side propulsion inverter cabinet and the side propulsion control box have the following connection relationship:

[0091] The side propulsion inverter cabinet is connected to the side propulsion control box and the side propulsion motor respectively;

[0092] The side propulsion control box is connected to the side propulsion motor and the driving console control unit group respectively.

[0093] The DC switchgear's power supply serves as the power source for the side thruster inverter. After the DC switchgear's power is converted to a voltage by the side thruster inverter, it is supplied to the side thruster motor. This design allows the side thruster motor to provide additional thrust as needed, helping the ship maintain stable navigation in complex sea conditions.

[0094] Regarding the layout of the side thruster control equipment, the side thruster control box can be installed in the bow sail cable compartment. Its power input is mainly drawn from the main switchboard and charging switchboard on the hull, ensuring sufficient power supply. At the same time, the side thruster control box can maintain a close connection with the side thruster inverter cabinet via the RS485 communication protocol, making data exchange and command transmission between the two more efficient and reliable.

[0095] The control unit on the bridge, a crucial component of the entire propulsion control system, receives operator commands and communicates with the side propulsion control box via CAN signals. This allows the operator to monitor the vessel's propulsion status in real time and adjust navigation modes and parameters as needed.

[0096] like Figure 7 The propulsion system also includes a ship-wide monitoring and alarm system, installed on the rear wall of the bridge. This system is connected to the control equipment group and, via the MODBUS-TCP protocol, to the side propulsion control box, enabling remote monitoring and management of the propulsion system. The system not only collects and analyzes data but also automatically adjusts and controls the system according to preset logic, significantly enhancing the intelligent navigation of the ship.

[0097] like Figure 8 The control unit group on the bridge console may include an emergency switch, which is connected to the control equipment group to ensure that the ship can respond quickly and take measures in an emergency.

[0098] like Figure 9 Emergency switches can include a main propulsion emergency switch and a side propulsion emergency switch. The main propulsion emergency switch is connected to the main propulsion control equipment group, and the side propulsion emergency switch is connected to the side propulsion control equipment group. These emergency switches are located in a prominent position on the navigation console and are directly connected to the power circuit inside the side propulsion control box and the side propulsion inverter cabinet.

[0099] Under normal operating conditions, the emergency switch is in the closed position, ensuring a stable power supply to the propulsion system. In the event of an emergency, the operator can quickly switch the emergency switch to the open position to immediately cut off the power supply to the propulsion inverter cabinet on the supply side, thereby stopping the operation of the propulsion motor, effectively avoiding potential safety risks or equipment damage.

[0100] The emergency switches can also be configured with a linkage function. This means that if a major fault occurs in a main propulsion motor power and control system, the corresponding emergency switch will automatically sense it and trigger a disconnection, further ensuring the safe operation of the ship. This intelligent design significantly improves system reliability and safety, enabling the ship to respond quickly to emergencies and effectively mitigating the impact of potential risks. This highly integrated design also makes the ship's overall operation more efficient and stable.

[0101] Based on the above embodiment, an embodiment of the present application further provides a ship, which includes the above-mentioned ship propulsion system.

[0102] In general, this application proposes a ship propulsion system and a ship, which have the following beneficial effects:

[0103] High system integration: Traditional marine propulsion systems have relatively independent components, lacking efficient data exchange and collaborative working mechanisms, which limits overall system performance. This marine propulsion system's components are interconnected, enabling efficient data exchange and collaborative working mechanisms.

[0104] Diversified Control Strategies: Traditional marine propulsion systems often rely on fixed-parameter control strategies, making it difficult to dynamically adjust to the vessel's actual operating conditions and environmental changes. This static control approach not only fails to fully realize the power system's potential but can also lead to energy waste and excessive equipment wear. This marine propulsion system, through programmable software, enables dynamic adjustments based on the vessel's actual operating conditions and environmental changes.

[0105] High Level of Intelligence: Traditional propulsion systems have shortcomings in data collection, processing, and analysis, lacking intelligent management and automatic adjustment capabilities. Operators must manually adjust navigation parameters, which is labor-intensive and error-prone. Furthermore, the system cannot predict or warn of potential failures, increasing safety risks in ship operations. This ship propulsion system can be programmed to enhance its data collection, processing, and analysis capabilities, enabling intelligent management and automatic adjustment capabilities, predicting and warning of potential failures, and reducing safety risks in ship operations.

[0106] Fast emergency response: In emergencies, traditional marine propulsion systems often fail to quickly shut down faulty power sources, leading to increased potential safety risks. Furthermore, the lack of interoperability between subsystems prevents coordinated response to emergencies, further reducing system reliability and safety. This marine propulsion system features an emergency switch to quickly shut down faulty power sources.

[0107] Environmentally friendly power source: Traditional marine propulsion systems rely on a single power source (such as a fuel engine), which not only limits the vessel's endurance but also increases environmental pollution. With increasingly stringent environmental regulations, traditional power sources are no longer able to meet the needs of green marine development. This marine propulsion system utilizes electricity as a power source, avoiding waste emissions and meeting the needs of green marine development.

[0108] In summary, this ship propulsion system has improvements in system integration, control strategy, intelligence level, emergency response speed and power source. The efficient, stable, intelligent and environmentally friendly battery-swap ship propulsion system has important practical significance and application value.

[0109] The above-described device and system embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. Those skilled in the art may understand and implement the present invention without inventive effort.

[0110] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
