Description

Technical Field

[0001] The present invention belongs to the field of ship power replacement, and specifically, the present invention relates to a ship power replacement method and system. Background Art

[0002] The existing ship battery replacement method uses a method of directly replacing containerized batteries to quickly replenish electricity. This solution requires port machinery to achieve lifting operations. Its initial construction cost is low, which helps operators reduce operating costs.

[0003] However, its shortcomings are also obvious. First, the containerized battery has a single use scenario and cannot realize battery sharing and replacement. It is only suitable for ship use. Secondly, the battery replacement method based on port crane hoisting needs to be carried out manually or semi-automatically, and cannot be fully automatic. At the same time, port cranes cannot provide battery replacement services alone, that is, the battery cannot be replaced during port crane operation, which requires a long waiting time and cannot truly improve the efficiency of power supply.

[0004] The comparative document (CN219727927U) discloses a lightweight supply and distribution system for marine box-type battery packs, including: a ship body, a control center, a loading and unloading device and a box-type battery pack; a ship body is fixed with a marine box-type battery pack guide rail; the loading and unloading device includes a host computer, a box-type battery pack positioning component, a box-type battery pack transfer component, and a box-type battery pack target position control component; the host computer realizes information collection and operation control of the box-type battery pack positioning component, the box-type battery pack transfer component, and the box-type battery pack target position control component, and realizes accurate positioning of the box-type battery pack to the target position; the utility model accurately delivers the box-type battery pack to the designated position through a lightweight supply and distribution system, which not only improves the positioning accuracy and reliability, but also avoids the difficulty and high cost of designing and manufacturing long booms, as well as the safety hazards caused by directly using long booms for lifting. However, the comparative document only solves the lifting problem of container-type batteries, and does not solve the problems of the single application scenario of container-type batteries themselves, nor does it involve the problem of battery replacement efficiency.

[0005] Therefore, in order to improve the efficiency of battery replacement, it is particularly important to develop an efficient ship battery replacement method or system. Summary of the invention

[0006] The present invention aims to overcome the deficiencies of the prior art and proposes a ship battery replacement method and system to achieve the purpose of improving the ship battery replacement efficiency.

[0031] Figure 1 This is a flow chart of a ship power replacement method according to an embodiment of the present invention;

[0032] Figure 2 The present invention is a schematic diagram of the structure of a ship power exchange system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0033] The following is a further detailed description of the specific implementation of the present invention by describing the embodiments with reference to the accompanying drawings, with the purpose of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation. In order to make the technical solution of the present invention clearer, the present invention is explained by the following embodiments.

[0034] Existing ports or docks usually use a containerized ship battery replacement method, but this method not only relies on the participation of dock cranes, but is also not suitable for small ships. In the prior art, in order to promote the sharing of vehicle and ship batteries, battery pack-type battery replacement has gradually become the mainstream, but the current battery replacement method is inefficient. To this end, this application proposes a ship battery replacement method, which is combined with Figure 1 A flow chart of a ship battery replacement method in the illustrated embodiment is described in detail.

[0035] As mentioned above, the wharf or port of this embodiment is equipped with a variety of battery replacement charging methods such as chargers, battery replacement vehicles, and cranes. Among them, the charger is used to charge and replenish depleted battery packs, battery replacement vehicles, and new energy ships; the battery replacement vehicle is used to replace batteries and transport battery packs for new energy ships; the crane is used for loading and unloading cargo on new energy ships and manually lifting and replacing battery packs on new energy ships.

[0036] A ship power replacement method, such as Figure 1 As shown, the method includes:

[0037] Step S1, establish communication with the ship, and drive the ship that needs to swap power into the pre-designated battery swap area at the dock.

[0038] In this embodiment, the dock or port is equipped with a WIFI communication device with a communication range of 100 meters. When a ship enters this communication area, the ship can establish a connection with the WIFI communication device, so that the dock or port can obtain ship information, including ship location information, power information (SOC), ship identification code and other data information.

[0039] In this embodiment, multiple battery swapping areas for ships are designated at the dock or port, and each battery swapping area must be able to accommodate one ship and be within the lifting range of the dock crane. When a ship needs to swap batteries for energy, the ship is driven into the pre-designated battery swapping area at the dock.

[0040] In order to ensure the safety of the ship during battery replacement, this embodiment also sets requirements for the ship's berthing accuracy. Specifically, before step S2, the method of this embodiment also includes: obtaining the ship's position information, and determining whether the berthing accuracy of the ship's berthing area in the pre-defined battery replacement area meets the preset berthing accuracy requirements.

[0041] In this embodiment, the berthing accuracy can be understood as the distance between the berthing position of the ship and the dock in the pre-defined battery swapping area of ​​the dock. The definition of the berthing accuracy can be flexibly selected according to different actual conditions. The berthing accuracy of this embodiment is preset to 1.5m, that is, when the berthing accuracy of the ship berthing area in the pre-defined battery swapping area is less than 1.5m, it is deemed to meet the preset berthing accuracy requirements; when the berthing accuracy of the ship berthing area in the pre-defined battery swapping area is greater than or equal to 1.5m, it is deemed not to meet the preset berthing accuracy requirements.

[0042] If the preset mooring accuracy requirement is not met, the ship is guided to perform a ship moving operation until the ship meets the preset mooring accuracy requirement. In order to improve the efficiency of ship moving, this embodiment adopts RTK positioning to guide the ship to perform a ship moving operation. RTK positioning method, the full name of which is real-time kinematic carrier phase differential technology (Real-time kinematic), is a technology that uses GPS carrier phase observations for real-time dynamic positioning. RTK positioning technology achieves centimeter-level positioning accuracy through data exchange between the base station and the mobile station, greatly improving operational efficiency. On the premise that the ship meets the preset mooring accuracy requirements, continue to execute step S2.

[0043] Step S2, obtain the number of ships within the communication range whose power (SOC) is less than the preset power threshold and their battery replacement needs. In this embodiment, the power threshold is set to 30% according to the operating capacity of the terminal. During the specific implementation, the power threshold can be flexibly configured according to the actual situation. The battery replacement demand indicates the number of battery replacement vehicles required for the corresponding ship. Under normal circumstances, one ship can be matched with one battery replacement vehicle, but due to the different specifications of battery replacement vehicles at different terminals and different ship models, the number of battery replacement vehicles required will also vary accordingly.

[0044] Step S3, obtaining the number of battery-changing vehicles within the communication range;

[0045] Step S4: According to the number of battery-swapping vehicles within the communication range, the number of ships with less than a preset power threshold and their power-swapping needs, it is determined whether the number of battery-swapping vehicles can meet the power-swapping needs of all ships. That is, the number of battery-swapping vehicles required can be counted according to the number of ships with less than a preset power threshold and their power-swapping needs. If the number of battery-swapping vehicles required is less than the current number of battery-swapping vehicles, it is determined that the number of battery-swapping vehicles cannot meet the power-swapping needs of all ships, otherwise, it can be met.

[0046] Step S5: When the number of battery-swapping vehicles cannot meet the battery-swapping needs of all ships, the wharf or port can activate a spare battery-swapping vehicle, or establish remote communication with other areas to remotely dispatch battery-swapping vehicles from other areas to join the battery-swapping tasks within the communication range; when the number of battery-swapping vehicles can meet the battery-swapping needs of all ships, a corresponding number of battery-swapping vehicles will be allocated to each ship according to demand.

[0047] Step S6, determine the status of the battery swap vehicle assigned to each ship; when the battery swap vehicle is in an available state, start automatically executing the battery swap task of the battery swap vehicle. When the battery swap vehicle is in an unavailable state (for example, the battery swap vehicle fails, there are insufficient available battery packs, etc.), further determine whether the dock crane can lift and replace the battery; when the dock crane can lift and replace the battery, manually lift the battery for ship battery replacement. When the dock crane cannot lift and replace the battery, guide the corresponding ship to charge the battery through the charger at the dock or port.

[0048] This embodiment adopts a variety of battery replacement methods, including battery replacement by battery swapping vehicle, battery replacement by crane, and direct charging by charger. Under normal circumstances, the battery replacement method mainly adopts battery replacement by battery swapping vehicle, which has high battery replacement efficiency. When the battery swapping vehicle is not available, the crane is considered to be used. When the crane is also not available, the charger is used as a last resort. The whole process is efficient and controllable.

[0049] Finally, after the ship completes the battery replacement, the replaced deflated battery pack will be sent to the charger for charging. Finally, the terminal or port will settle the ship's battery replacement fee based on the charging degree of the charger (including the degree of charging the ship's battery directly by the charger, and the charging degree of the replaced deflated battery pack).

[0050] At the same time, this embodiment constructs a ship power replacement system according to the above-mentioned ship power replacement method, such as Figure 2 As shown, the system includes a charger, a battery-swapping vehicle, a crane, a control cabinet, a WIFI communication device, a ship guidance device, a battery-swapping controller, a charging settlement module, a vehicle dispatching module, and a fault reminder module; wherein:

[0051] The control cabinet is used to control the charger, battery swap vehicle, crane and ship; the control cabinet includes a human-computer interaction interface, which supports the control of the charger, battery swap vehicle, crane and ship through human-computer interaction; in this embodiment, the control cabinet can adopt a programmable logic controller PLC, etc., which can be flexibly selected according to actual conditions.

[0052] The WIFI communication device is used to realize remote communication between the control cabinet and the charger, battery-changing vehicle, crane, and ship.

[0053] The ship guiding device is used to guide the ship into the power exchange area according to the control command of the control cabinet.

[0054] The battery swap controller is used to send corresponding control signals to the charging settlement module, vehicle dispatching module, and fault reminder module according to the control command of the control cabinet to settle charging and swapping fees, dispatch battery swapping vehicles, and remind equipment failures. The battery swap controller can use control chips such as microcontrollers and central processing units to improve control efficiency and reduce system size.

[0055] The charging settlement module is used to access the charger according to the control signal of the battery replacement controller to obtain the charging degree of the charger for settlement.

[0056] The vehicle dispatching module is used to obtain the number of ships and battery swapping vehicles in the battery swapping area after receiving the control signal of the battery swapping controller, calculate whether the number of battery swapping vehicles meets the battery swapping demand, and dispatch battery swapping vehicles in other areas when the battery swapping vehicles in this area do not meet the battery swapping demand.

[0057] The fault reminder module is used to monitor the status of the battery swap vehicle and crane, and to give a reminder when a fault occurs according to the control signal of the battery swap controller, to remind the dock crane to intervene in the battery swap operation when the battery swap vehicle cannot work, and to remind the operation and maintenance personnel to charge the ship through the charger when the dock crane cannot perform manual lifting. Specifically, the user can be reminded by voice alarm, buzzer alarm, indicator light alarm, etc., which can be flexibly selected according to the actual situation.

[0058] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
