[0003] Especially in special scenarios like airport flight zones, where safety, airspace clearance, and construction management are extremely stringent, the shortcomings of existing charging solutions are further amplified, even rendering them completely unusable. Green islands within flight zones are crucial working areas for intelligent devices such as bird-repelling robots, but these areas typically lack power grid coverage, and infrastructure development is difficult to approve. The entry and exit of personnel and equipment are strictly controlled, and the robots themselves require periodic (e.g., every 7 to 30 days) rotation deployment between different green islands based on factors such as bird activity patterns.

[0004] Against this backdrop, fixed charging piles are unusable due to difficulties in grid connection and construction approval; the noise and exhaust pollution from fuel generators severely violate the environmental protection and quiet requirements of the flight area, and frequent refueling is required, making personnel access inconvenient and maintenance impossible; photovoltaic power generation equipment is unstable, heavily dependent on weather conditions, cannot provide a stable current, and cannot move with robots, rendering it meaningless; therefore, existing technologies are completely unable to meet the special needs of airport flight areas, which are characterized by short-term, mobile, infrastructure-free, and high-safety requirements, constituting a key bottleneck in intelligent airport ground management.

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort should fall within the scope of protection of this invention.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] As mentioned in the background section, existing charging solutions for smart devices in outdoor off-grid scenarios suffer from inflexible deployment, high maintenance costs, and inability to adapt to the specific needs of airport flight zones. To address these issues, this invention provides a photovoltaic wireless charging base station.

[0024] Referring to Figures 1-6, Figure 1 is a system structure block diagram of a photovoltaic wireless charging base station according to an embodiment of the present invention. As shown in Figure 1, a photovoltaic wireless charging base station includes a structural support module, a photovoltaic power generation unit, an intelligent control module, an energy storage module, a wireless charging module, and a cloud service platform. The intelligent control module is electrically connected to the photovoltaic power generation unit, the energy storage module, and the wireless charging module, and is communicatively connected to the cloud service platform through the wireless communication module.

[0025] Specifically, as shown in Figure 2, the photovoltaic wireless charging base station consists of a base station body and multiple modular photovoltaic panels. The base station body is a box structure with wheels, and the multiple photovoltaic panels are connected to the base station body through brackets. The whole structure has a decomposed modular design, which facilitates transportation and rapid deployment.

[0026] Furthermore, the structural support module is a modular bracket that can be quickly deployed and folded, used to support and secure the photovoltaic power generation unit and other functional modules. The structural support module includes a foldable bracket and quick-connect components. Once the entire system is transported to the target location by personnel, the bracket can be deployed and secured, and wiring connected within a short time (less than 30 minutes). The entire process requires no civil engineering work or cable laying, and has no impact on the ground or airspace of the flight area. Disassembly and reassembly time is less than 5 minutes, perfectly adapting to the 7-30 day robot rotation deployment requirements.

[0027] Furthermore, as shown in Figure 3, the photovoltaic power generation unit is a modular photovoltaic panel assembly. Multiple photovoltaic panels are installed around the base station body through tilted brackets to convert solar energy into electrical energy. The number of photovoltaic panels can be increased or decreased according to the power generation demand to improve power generation efficiency.

[0028] Specifically, as shown in Figure 4, the front of the base station has three energy storage module battery compartments arranged side by side. The energy storage module includes three independent pluggable battery packs, namely the main power supply battery pack C0, the first backup battery pack C1, and the second backup battery pack C2, which are used to store the electrical energy generated by the photovoltaic power generation unit. The top of the base station has signal lights and communication antennas, and the center of the front has a cooling fan for heat dissipation. Each battery pack adopts a quick-release structure, which can be a pull-out quick-release structure or a knob locking quick-release structure, which can be quickly pulled out from the base station for direct battery swapping, providing emergency energy supply for smart mobile devices.

[0029] Furthermore, as shown in Figure 5, the base station has a box-like structure with a calibration sensor and communication antenna on the top and a wireless charging module on the side. The wireless charging module is used to wirelessly charge intelligent mobile devices such as bird-repelling robots. The base station has casters at the bottom for easy transport and repositioning. When wireless charging cannot meet emergency needs, staff can quickly remove a fully charged battery pack (such as C1) from the base station to directly replace the robot's battery, providing a highly reliable power replenishment solution in addition to wireless charging, which greatly ensures the continuity of the mission.

[0030] Furthermore, as shown in Figure 6, the base station body has multiple photovoltaic panel connection interfaces on its sides for connecting modular photovoltaic panels, allowing for flexible configuration of the number of photovoltaic panels according to actual needs. The base station body has a communication antenna and signal lights on the top, cooling fans on the sides, and four casters on the bottom, resulting in a compact overall structure that facilitates mobile deployment.

[0031] Specifically, the intelligent control module is electrically connected to the photovoltaic power generation unit, energy storage module, and wireless charging module, respectively, to execute a multi-battery pack intelligent scheduling algorithm and control the charging and discharging priorities and switching of each battery pack. The intelligent control module also includes a power detection unit, which is used to detect the power level and state of health (SOH) of each battery pack in real time and upload the detection information to the cloud service platform.

[0032] Furthermore, the specific execution logic of the multi-battery pack intelligent scheduling algorithm is as follows: In photovoltaic power generation charging mode, the intelligent control module controls the photovoltaic power generation unit to prioritize charging the main power supply battery pack C0. When the main power supply battery pack C0 is fully charged, it then charges the first backup battery pack C1 and the second backup battery pack C2 in sequence. In wireless charging power supply mode, when the smart mobile device is wirelessly charged, the main power supply battery pack C0 is given priority. When the main power supply battery pack C0 is low on power, the intelligent control module automatically switches to the first backup battery pack C1. When the first backup battery pack C1 is low on power, it automatically switches to the second backup battery pack C2. When there is sufficient sunlight, the photovoltaic power generation unit can bypass the main power supply battery pack C0 and directly charge the first backup battery pack C1 and the second backup battery pack C2, improving overall energy efficiency. The intelligent control module dynamically adjusts the switching order of the battery packs according to the health status assessment value (SOH) of each battery pack, prioritizing the use of battery packs with better health status, thus extending the overall service life of the system.

[0033] Preferably, the specific formula for the health status assessment value is as follows: ;in, This is the health status assessment value for the i-th battery pack; The current usable capacity of the battery pack is estimated by combining ampere-hour integration and open-circuit voltage calibration. This refers to the nominal capacity of the battery pack at the factory. This is the capacity-weighted adjustment index; The battery pack's historical average operating temperature and ambient reference temperature The difference; This is the internal resistance of the battery pack currently measured using the DC pulse method; This is the minimum internal resistance measured during the battery pack's lifespan (which can be approximated by the initial internal resistance). The internal resistance threshold defined when the battery life ends (typically corresponding to capacity decay to 80%); This is the reference value for normalized internal resistance.

[0034] It should be noted that the health status assessment value The range is theoretically approximately (0, 1); when When ≈1, it indicates that the battery pack is in excellent condition, with capacity close to the nominal value and internal resistance extremely low, and ideal temperature operating conditions; when 0.8 < When the value is less than 1, it indicates that the battery pack is healthy and is a priority target in the intelligent scheduling algorithm; when 0.6 < When the value is ≤0.8, it indicates that the battery pack is slightly aging. During scheduling, the priority should be appropriately reduced, and high-current usage should be minimized. When the value is ≤0.6, it indicates that the battery pack has aged significantly, with obvious capacity decay or increased internal resistance. The system should trigger a maintenance warning and treat it as a last resort in the scheduling process. Close to or greater than When the logarithmic terms cause the second factor to approach 0 or a negative value, the health status assessment value will be... It will drop sharply to near 0, which provides a failure warning function.

[0035] Furthermore, the cloud service platform communicates with the intelligent control module via a wireless communication module. The wireless communication module can be one or more of the following: NB-IoT communication module, Wi-Fi communication module, or satellite communication module. The intelligent control module uploads base station status, battery level, charging and discharging status, fault information, etc., to the cloud service platform in real time. Off-site maintenance personnel can remotely monitor the status of all deployment points through the cloud service platform, realizing centralized monitoring and management of multiple deployment points, significantly reducing the frequency of entering the flight area, which not only meets safety control requirements but also improves maintenance efficiency.

[0036] Specifically, the main control circuit board packages the collected real-time data into status data packets and sends these packets to the cloud service platform via the communication module. Upon receiving the status data packets, the cloud service platform's data receiving server writes the extracted real-time data into the data storage database. The data analysis server reads the latest real-time data from the data storage database and assesses the power and temperature status of each battery pack. When the power of any battery pack falls below a second preset threshold or the temperature data is abnormal, the data analysis server 1 generates an early warning message. The cloud service platform sends an early warning notification to the mobile terminal of maintenance personnel via message push service. After receiving the early warning notification, maintenance personnel can go to the photovoltaic wireless charging base station for on-site handling. When emergency battery swapping is required, maintenance personnel release the locking state of the movable latch, pull the target battery pack outward along the fixed guide rail, and push the fully charged battery pack into the battery compartment to complete the emergency battery swapping operation.

[0037] Furthermore, when the rotation cycle arrives, maintenance personnel dismantle and relocate the photovoltaic wireless charging base station. They first disconnect the electrical connections, dismantle the photovoltaic charging units and energy storage modules, and remove the structural support modules. All dismantled components are then transported to the next target green island area, where the photovoltaic wireless charging base station is redeployed.

[0038] In summary, this invention achieves rapid deployment and dismantling of base stations by using a modular support structure that can be quickly deployed and folded, allowing installation without civil engineering construction and fundamentally avoiding the problems of difficult and lengthy approval processes for fixed infrastructure construction. By designing the energy storage module as three independent pluggable battery packs (C0, C1, and C2), redundant backup of energy storage is achieved, improving the reliability and fault tolerance of the system power supply. By implementing a multi-battery pack intelligent scheduling algorithm, the main power supply battery pack is charged first in charging mode, and then the backup battery packs are charged sequentially after being fully charged, ensuring that the main power supply battery pack is always in the optimal state of charge. By setting an automatic battery pack switching mechanism in power supply mode, seamless connection of the power supply process is achieved, ensuring uninterrupted and continuous power supply. Power supply: By setting up an energy direct path to charge the backup battery pack directly, bypassing the main power supply battery pack when there is sufficient sunlight, secondary energy conversion losses are reduced, while the cycle number of the main power supply battery pack is reduced, improving system energy efficiency and extending battery life; The quick-release structure design provides an emergency channel for direct battery swapping when wireless charging cannot meet urgent needs, achieving dual protection of wireless charging and emergency battery swapping; By dynamically adjusting the switching sequence according to the battery pack's State of Health (SOH), intelligent optimization of battery usage strategy is achieved, balancing battery losses; By using a combination of multiple wireless communication methods, the stability of remote monitoring under different network environments is ensured; The modular photovoltaic panel design enables flexible expansion of power generation capacity.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
