Description

Technical Field

[0001] This utility model relates to the field of control of new energy battery swapping boats, and in particular to a battery swapping and berthing control system for new energy battery swapping boats. Background Technology

[0002] Ship berthing systems primarily employ traditional cable mooring. Traditional cable mooring requires manual operation by crew members to throw the cable from the ship to the dock or other vessels for securing it, as described in Chinese Patent CN110733543A, "A Ship Berthing System." This system uses multiple sets of cables and winches to connect and secure the ship to the dock. However, this method is complex, requires professional personnel, and poses safety hazards in adverse weather conditions.

[0003] However, with the development of ship technology, ship propulsion systems are gradually shifting towards electrification. Battery-swapping vessels, as a new type of green vessel, offer advantages such as rapid refueling and zero emissions, and are increasingly being applied in the water transportation sector. During battery swapping operations on new energy battery-swapping vessels, the swapping vessel and the vessel being swapped need to be close together and maintain a relatively stable position to ensure the safe transfer and docking of the battery pack. However, using traditional cable mooring methods requires simultaneously mooring both vessels, which is difficult and complex, and cannot guarantee the relative stability of the two vessels, affecting the battery swapping control between the swapping vessel and the electric vessel, thus failing to meet the requirements. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a battery swapping docking control system for new energy ships. It uses electromagnetic adsorption to set an adsorption state on the battery swapping ship to attract the electric ship and the battery swapping ship together. The operation and control are simple and can be automated, stable and reliable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a battery swapping docking control system for a new energy ship battery swapping vessel, including a magnetic attraction device, a control unit, a power supply, and an electronic switch installed on the battery swapping vessel and / or the vessel to be swapped.

[0006] The power supply is connected to the power supply terminal of the magnetic attraction device via an electronic switch; the output terminal of the control unit is connected to the electronic switch to control the opening or closing of the electronic switch.

[0007] The control unit is connected to the shipboard controller and is used to receive the battery swapping command sent by the shipboard controller and control the electronic switch according to the command.

[0008] Magnetic suction devices are installed on the side hull of the battery swapping vessel and / or the vessel to be swapped.

[0009] The number of magnetic attraction devices installed on the battery swapping boat or the boat to be swapped is multiple.

[0010] The control unit is connected to a distance sensor to detect the distance between the battery swapping boat and the boat to be swapped when the battery swapping begins; the control unit controls the on / off state of the electronic switch of each magnetic attraction device based on the distance.

[0011] The power supply is an adjustable power supply. The control unit is connected to a weather status sensor to collect current weather and hydrological data. The output of the control unit is connected to the adjustable power supply to adjust the current output of the adjustable power supply.

[0012] The control unit is connected to the emergency power-off device, and the control unit controls the emergency disconnection of the electronic switch according to the signal from the emergency power-off device.

[0013] The emergency power-off device includes an emergency stop button installed on the ship's control panel. After receiving a signal from the emergency stop button, the control unit controls the electronic switch to disconnect in an emergency.

[0014] The electronic switch is a relay or a contactor.

[0016] The following is a brief explanation of the contents of each of the accompanying drawings and the markings in the drawings:

[0017] Figure 1 This is a block diagram of the control architecture of the control system of this utility model. Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0019] The battery swapping vessel berthing control system provided in this embodiment, being in the field of battery swapping vessels, requires reduced or complete static relative motion between the two vessels to meet the battery swapping needs. Therefore, unlike traditional berthing ports, it cannot be quickly moored using simple ropes or similar methods. To solve this technical problem, this solution employs the principle of magnetic attraction to tightly attract the two vessels together, achieving relative stillness and providing the basic conditions for battery swapping. The magnetic attraction device in this solution uses an electromagnet, which generates different magnetic fields under energized and de-energized conditions for magnetic attraction control. Existing technologies require two vessels to be closely aligned to ensure normal battery swapping operations, but lack effective mooring methods to ensure stable approach during the process, leading to safety hazards and operational difficulties. This solution addresses this by installing an electromagnet device at a fixed position on the side of the vessel. By controlling the electromagnet's attraction during battery swapping, the two vessels are brought close together for berthing, thus achieving the purpose of battery swapping. A magnetic attraction device is used to moor two boats; the magnetic attraction device generates attraction when energized; the magnetic attraction device has no attraction when not energized. The magnetic attraction device is installed on the relatively close sides of the two boats, and the positions are corresponding to each other to ensure that the attraction effect is generated when energized.

[0020] like Figure 1 As shown in this embodiment, a battery swapping docking control system for a new energy ship includes a magnetic attraction device, a control unit, a power supply, and an electronic switch installed on the battery swapping ship and / or the ship to be swapped.

[0021] The core of the magnetic attraction device is an electromagnet, which generates magnetic force when energized and disappears when de-energized. Since battery swapping requires the two vessels to be close together, the magnetic attraction device is installed on the side hull of the vessel swapping the battery and / or the vessel to be swapped. This allows the two vessels to be magnetically attracted together, providing the necessary conditions for battery swapping.

[0022] The power supply provides basic power to the magnetic attraction device, and is connected to the power supply terminal of the magnetic attraction device via an electronic switch. The power on or off of the magnetic attraction device is controlled by opening and closing the electronic switch. In this embodiment, the electronic switch can be implemented using relays, contactors, or other electronic switches, enabling rapid on / off control.

[0023] The control unit, as the core of the control system, has its output connected to the electronic switch to control the opening and closing of the electronic switch. The control unit can be implemented using common microprocessors, including but not limited to 51 series microcontrollers and STM32 series microcontrollers. It mainly implements the drive control of the electronic switch, and uses the microcontroller to drive the relay to realize the opening and closing of the relay, thereby realizing the control of the power supply of the magnetic attraction device.

[0024] The control unit connects to the ship's onboard controller to receive battery swapping commands and control the electronic switch accordingly. The onboard controller, such as the controller within the ship's control console, primarily receives user commands for battery swapping. The onboard controller connects to the ship's human-machine interface (HMI). Users input the battery swapping start command through the HMI, which is then sent to the control unit via the onboard controller. The control unit then energizes the electronic switch to activate the magnetic traction device. Specifically, the HMI can input the user's battery swapping start command via a touchscreen, switch, or button on the ship's control panel. The command is transmitted to the control unit via the controller within the control console, which then controls the magnetic traction device's power supply.

[0025] Its working principle is as follows: The user inputs the battery swap start command on the ship's control console. After receiving the battery swap start command, the control unit drives the electronic switch to close and controls the electromagnet in the magnetic attraction device to be energized. The energized electromagnet has a strong attraction capacity, which can attract the two ships associated with the battery swap together, providing a basic stable condition for the battery swap. After the battery swap is completed, the connection between the two ships can be disconnected by opening the electronic switch.

[0026] In a preferred embodiment, the number of magnetic attraction devices installed on the battery swapping vessel or the vessel to be swapped is multiple. Since the vessel is large, the magnetic attraction force generated by a single magnetic attraction device may not be sufficient for the vessel to be stably moored. Therefore, installing multiple devices can generate a larger magnetic attraction force, thereby meeting the requirements for battery swapping.

[0027] In this embodiment, due to the movement of ships on the water surface, all electromagnets cannot be activated suddenly when two ships are attracted together, as this would lead to a collision and prevent proper positioning. Therefore, in this embodiment, the energization of each electromagnet is controlled sequentially based on distance during mooring, thereby gradually strengthening the attraction. The scheme includes a control unit connected to a distance sensor to detect the distance between the swapping ship and the ship to be swapped at the start of the swapping process. The control unit controls the on / off state of the electronic switches of each magnetic attraction device based on the distance. The working principle is as follows: After the swapping process begins, the control unit controls a small number of electromagnets to be energized based on the current distance signal. The resulting magnetic force attracts the other ship, but the overall attraction force is not particularly strong. The other ship can then adjust its position to approach the swapping ship using its power. As the ship gets closer, the energization of the electromagnets is increased again, generating a stronger attraction force, causing the two ships to gradually approach each other. By gradually increasing the number of electromagnets energized during the approaching process, the electromagnetic attraction force is increased, thus meeting the attraction requirements during the approaching process and avoiding a collision and inability to adjust position caused by energizing all electromagnets at once. By increasing the energization of the electromagnet as the two vessels approach each other, effective attraction can be achieved without significant collisions. The system can also automatically activate the electromagnet when the two vessels are within a predetermined distance, enabling automatic mooring.

[0028] In this embodiment, the power supply is an adjustable power supply. The control unit is connected to a weather sensor to collect current weather and hydrological data. The output of the control unit is connected to the adjustable power supply to adjust the current output of the power supply. The attraction force of the electromagnets can be precisely adjusted through control to adapt to mooring requirements under different weather and hydrological conditions. Since weather and wind have a significant impact on the battery swapping of ships, a stronger electromagnetic field is required to generate a greater attraction force when there is strong wind or rain. Therefore, the output current of the power supply can be controlled according to the current weather and hydrological conditions, such as wind and rain, thereby adjusting the magnetic field of each electromagnetic device to adjust its attraction force.

[0029] In this embodiment, the control unit is connected to the emergency power-off device. The control unit controls the emergency disconnection of the electronic switch based on the signal from the emergency power-off device. The emergency power-off device includes an emergency stop button located on the ship's control panel. Upon receiving a signal from the emergency stop button, the control unit controls the emergency disconnection of the electronic switch. After the emergency stop button is pressed, the control unit immediately disconnects the electronic switches of all electromagnetic devices, thereby achieving the purpose of emergency disconnection of the adsorption. In the event of an emergency, the adsorption state between the two ships can be quickly released.

[0030] The beneficial effects of this invention are as follows: By employing a magnetic mooring device, when a battery swap is needed, an attractive force is generated to bring the two vessels close together. After the swap is completed, the power is cut off to release the attraction. Compared to the mechanical mooring methods used in the prior art, this method effectively ensures the stable approach of the two vessels during the battery swap process, improving the safety and reliability of the operation. Simultaneously, this mooring method is simple to operate; mooring and unmooring can be completed simply by controlling the power supply, eliminating the need for complex manual mooring operations and greatly improving work efficiency. Furthermore, because the magnetic device can precisely control the magnitude of the attraction force, it can adapt to mooring requirements under different hydrological and weather conditions, enhancing the system's adaptability and stability. In emergencies, a rapid power cut-off can immediately disconnect the two vessels, improving emergency response capabilities and further ensuring the safety of the battery swap operation.

[0031] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
