Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the embodiments of this application will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 An architecture diagram of a vehicle / ship battery swapping positioning system provided in this application embodiment;

[0020] Figure 2 This is a schematic diagram of the battery swapping vehicle and battery swapping boat provided in the embodiments of this application. Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Current vehicle battery swapping methods typically involve driving the vehicle into the swapping station and parking it at a designated swapping location. A 2D or 3D camera on the underside of the vehicle is used to locate the battery pack, and then position compensation is used to disassemble and install the battery pack. However, this operation usually takes place inside the swapping station, in an indoor environment.

[0023] When swapping batteries for ships, ships cannot drive into the battery swapping station like vehicles. Battery swapping sites are generally located at docks or ports. Conventional vehicle battery swapping positioning methods (such as 2D cameras, 3D cameras, displacement sensors, laser sensors, etc.) are limited by the outdoor environment. Outdoor sunlight, rain, dust, etc. will cause such positioning methods to fail to work effectively.

[0024] Therefore, this application provides a vehicle and vessel battery swapping positioning system to solve the above-mentioned problems in the prior art, which can accurately locate the position of battery swapping vehicles and vessels to improve battery swapping efficiency.

[0025] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application. Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0026] like Figure 1 As shown, this application provides a vehicle and vessel battery swapping positioning system, which includes: a controller 3, a first position collector 11, a second position collector 21, battery swapping communication equipment, and a lifting device;

[0027] Among them, the battery swapping vehicle 1 is equipped with a first position acquisition device 11, a battery swapping communication device 12 and a lifting device;

[0028] The battery swapping boat 2 is equipped with a second location acquisition device 21 and a battery swapping communication device 22; that is to say, both the battery swapping vehicle and the battery swapping boat are equipped with battery swapping communication devices.

[0029] The controller 3 is installed on the battery swapping vehicle 1 or the battery swapping boat 2.

[0030] The transmitting end and the receiving end of the battery swapping communication equipment are connected for communication.

[0031] The controller 3 is connected to the first position acquisition device 11, the second position acquisition device 21, the battery swapping communication device, and the lifting device.

[0032] The battery swapping boats are equipped with fully charged battery boxes and / or depleted battery boxes. The battery swapping vehicles are equipped with fully charged battery boxes and depleted battery boxes.

[0033] In some embodiments, the lifting device can be a battery swapping robotic arm, which is used to automatically lift fully charged battery boxes from battery swapping vehicles and depleted battery boxes from battery swapping boats to perform battery swapping operations.

[0034] Combination Figure 2 As shown, the system also includes a shore-based reference station 4; the shore-based reference station 4 is fixed at the shore and is used to provide position reference data.

[0035] The battery swapping communication equipment can be understood as a vehicle-to-ship communication system, used for data exchange between battery swapping vehicles and ships. The battery swapping vehicle carries the transmitter of the communication equipment, while the ship carries the receiver. When the ship enters the working area of ​​the battery swapping vehicle, it will automatically connect. The current effective communication distance is 100 meters.

[0036] The first location data collector can also be understood as a ship-side rover station, which is set on the base of the battery box; it uses data provided by the shore-side base station 4 for precise RTK positioning.

[0037] The second location data collector can also be understood as a vehicle-mounted mobile station, installed on the top of the spreader, and uses data provided by the shore-based base station 4 for precise RTK positioning.

[0038] The system also includes an RTK data receiving device, which is communicatively connected to the first and second position data collectors, and is used to receive RTK data (relative coordinates of the battery swapping boat and the battery swapping vehicle) collected by the first and second position data collectors. It can be understood that the first and second position data collectors collect the corresponding (X, Y, H) coordinates.

[0039] In some embodiments, the controller can also be understood as the controller of the vehicle control system, mounted on the battery swapping vehicle, for managing the battery swapping communication equipment, RTK data receiving equipment and battery swapping robotic arm through electrical signals.

[0040] The working process of the vehicle / ship battery swapping positioning system provided in this application is as follows:

[0041] After the battery swapping boat enters the battery swapping area, the WIFI communication device on the battery swapping boat receives the signal from the WIFI communication device on the battery swapping vehicle. At this time, the transmitter and receiver of the battery swapping communication equipment will detect the corresponding signal, that is, automatically detect the communication status.

[0042] When the controller receives a battery swapping order from the crew via a terminal on the battery swapping vessel, the controller acquires RTK data of the battery swapping vehicle and the battery swapping vessel through the first and second location acquisition devices; and uses the corresponding RTK data to determine the relative distance between the battery swapping vessel and the battery swapping vehicle through the RTK data receiving device.

[0043] The RTK data mainly includes the (X, Y, H) coordinate information based on the base station, the coordinate information of the battery swapping boat, and the coordinate information of the battery swapping vehicle. For example, the base station is (0, 0, 0), the battery swapping boat is (-3, 6, -10), and the battery swapping vehicle is (5, -20, 50), with the unit being cm.

[0044] Then, the controller determines whether the relative distance is within the working range of the battery swapping robotic arm.

[0045] If not, the battery swapping vehicle or vessel will be moved (vehicle movement will be prioritized, and vessel movement will only be carried out if vehicles cannot be moved).

[0046] If so, the relative angular deviation between the battery swapping vehicle and the battery swapping boat is calculated using the calculation rules (Pythagorean theorem) set in the controller.

[0047] The controller controls the battery swapping robotic arm to rotate to the position of the battery swapping boat according to the relative angle deviation through corresponding signals. Then, it controls the battery swapping robotic arm to extend to the appropriate length according to the relative distance through corresponding signals. Finally, it controls the battery swapping robotic arm to extend the cable according to the relative height deviation between the battery swapping vehicle and the battery swapping boat through corresponding signals to carry out battery lifting operations.

[0048] This application provides a vehicle-to-vehicle battery swapping positioning system, comprising: a first position acquisition device and a lifting device both mounted on the battery swapping vehicle; a second position acquisition device mounted on the battery swapping vessel; battery swapping communication equipment installed on both the battery swapping vehicle and the battery swapping vessel; a controller mounted on either the battery swapping vehicle or the battery swapping vessel; a transmitter and a receiver of the battery swapping communication equipment communicatively connected; and the controller communicatively connected to the first position acquisition device, the second position acquisition device, the battery swapping communication equipment, and the lifting device. This application employs RTK positioning, solving the problem that visual and laser positioning cannot function effectively in outdoor environments, further improving the efficiency of vehicle-to-vehicle battery swapping.
