Each energy storage component has pre-set positive and negative terminals, which are connected in series / parallel via pre-embedded copper busbars to form an energy storage array.

[0059] The matrix-distributed wireless charging base station adopts a matrix grid layout. The distance between adjacent base stations is set at 200-500 meters based on the drone's operating radius and endurance.

[0061] See Figure 1 Charging process: When the drone's battery level is below 30%, it autonomously plans its return path and flies to the nearest base station. The base station guides the drone to land on the charging platform through UWB positioning and visual guidance. After landing, the drone and the base station handshake authentication through near field communication (NFC) to start wireless charging. The BMS dynamically adjusts the charging power according to the drone's battery demand and the base station's energy storage capacity. Once fully charged, the power is automatically cut off, and the drone takes off to continue working, forming a complete automated closed loop of "operation-return-charging-re-operation", without any human intervention.

[0082] Monitoring and Management Phase: Technicians monitor the overall system operation status in real time on the central control screen, and issue dispatch instructions, view alarm information, and generate maintenance work orders through the management and control platform.

[0083] Example 3

[0084] Taking 100 mu (approximately 6.7 hectares) of farmland as an example, six matrix-distributed wireless charging base stations are deployed. This is based on the fact that agricultural drones typically require 7-9 square meters of space for operation and parking. 2 Each base station is designed to occupy an area of ​​4×4 m. This invention... The energy density of the mineralized cement-based battery is 7.82 Wh / kg, and a 20 cm thick layer of cement is laid at the bottom of the base station. Mineralized cement-based batteries can store 55 kWh of electrical energy.

[0085] The photovoltaic (PV) panel on the top of the base station has an area of ​​4m × 4m. Currently, the photoelectric conversion efficiency of mainstream monocrystalline silicon PV panels is approximately 20-23%. Under standard test conditions (illuminance 1000W / m², cell temperature 25℃), the power generation per square meter of PV panel is 200-220W. Assuming an average daily effective sunshine duration of 6 hours, the theoretical power generation per square meter of PV panel per day is 1.2-1.32 kWh. Considering factors such as dust obstruction and cable loss, the actual power generation per square meter of PV panel per day is approximately 0.72-0.96 kWh. Therefore, the daily power generation of a 4m × 4m PV panel is 19.2-21.12 kWh. The base station also has a 300W wind turbine on top. In agricultural areas, the average wind speed is 3-4 m / s. Under conditions of 8 hours of operation per day, the wind turbine generates approximately 0.6-0.8 kWh per day. Therefore, the total daily power generation of a single base station is 19.8-21.92 kWh.

[0086] Currently, mainstream agricultural drones consume approximately 1.0~1.6 kWh of power per operation. Taking the DJI T40 as an example, its 52.22V / 30000mAh battery pack has a capacity of 1.57 kWh, providing only 7.5 minutes of full-load flight time; the XAG P60 Pro, with its 52.5V / 20Ah battery pack, has a capacity of 1.05 kWh, providing approximately 15-20 minutes of operation per run. Based on this calculation, a single drone needs to be charged 15 to 20 times for continuous operation throughout the day, consuming a total of approximately 20 kWh of power.

[0087] The power supply system of the present invention, in order to The energy density calculation for mineralized cement-based batteries, at 7.82 Wh / kg, requires only a 20 cm thick layer of cement. Mineralized cement-based battery layers can store the electricity required for a single drone flight. Through large-scale deployment (such as approximately 56 Wh of ground-based energy storage in a 100-square-meter control center, combined with energy storage modules at the bottom of each base station), the distributed energy needs for high-frequency charging of drones can be fully met.

[0088] This invention employs a matrix-distributed wireless charging base station, which reduces the distance between base stations to within 500 meters through a modular matrix layout, making it compatible with the effective operating radius of mainstream drones. Drones can land and charge on demand, increasing the number of effective daily operating cycles from less than 10 in the traditional model to over 15, and the daily operating area per drone from hundreds of acres to thousands of acres, significantly improving the operational efficiency of drones in smart agriculture.

[0089] The above embodiments are merely illustrative of the present invention and are not intended to limit the invention. Any obvious modifications made by those skilled in the art without departing from the principles and spirit of the present invention should be considered to be included within the scope of protection of the claims of the present invention.
