Abstract

Methods, devices, and systems of various embodiments are disclosed for managing an unmanned aerial vehicle (UAV) charging station having a docking terminal. In various embodiments, a priority of a first UAV and a second UAV may be determined for using the docking terminal when a docking request is received from the second UAV while the first UAV occupies the docking terminal. In some embodiments, the priorities of the first and second UAVs may be based on an available power level of each of the first and second UAVs. The first UAV may be instructed to undock from the docking terminal in response to determining that the second UAV has a higher priority.

First claim

What is claimed is:

1. A method for managing an unmanned aerial vehicle (UAV) charging station, comprising:
receiving, in a processor, docking requests from UAVs;
determining, by the processor, a priority of a first UAV and a priority of a second UAV for using a docking terminal of the UAV charging station based on an available power level of each of the first and second UAVs; and
instructing the first UAV to undock from the docking terminal in response to determining that the priority of the second UAV is greater than the priority of the first UAV.

2. The method of claim 1 , further comprising:
establishing a communication link between the UAV charging station and the second UAV; and
receiving, in the processor, the available power level and a UAV ranking from the second UAV,
wherein determining the priority of the first UAV and the priority of the second UAV for using the docking terminal comprises determining priorities of the first and second UAVs for using the docking terminal by weighing the available power level and the UAV ranking of each of the first and second UAVs.

3. The method of claim 2 , wherein the available power level is weighted more heavily than the UAV ranking when determining the priorities of the first and second UAVs for using the docking terminal in response to the available power level of either the first or second UAVs being below a threshold.

4. The method of claim 2 , wherein the UAV ranking is given no weighting when determining the priorities of the first and second UAVs for using the docking terminal in response to the available power level of either the first or second UAVs being below a threshold.

5. The method of claim 2 , wherein the available power level is given no weighting when determining the priorities of the first and second UAVs for using the docking terminal in response to the UAV ranking of either the first or second UAVs being above a predetermined ranking.

6. The method of claim 1 , further comprising:
establishing a communication link between the UAV charging station and the second UAV; and
receiving, in the processor, the available power level from the second UAV,
wherein determining the priority of the first UAV and the priority of the second UAV for using the docking terminal comprises determining priorities of the first and second UAVs for using the docking terminal based on the available power level of each of the first and second UAVs.

7. The method of claim 1 , wherein one or more of the received docking requests from UAVs include information selected from a group consisting of UAV identification, UAV authentication information, UAV ranking, the available power level, and how long the second UAV has been waiting to dock at the UAV charging station.

8. The method of claim 1 , wherein instructing the first UAV to undock from the docking terminal includes information about another charging station to which the first UAV may dock.

9. The method of claim 1 , wherein instructing the first UAV to undock from the docking terminal comprises authorizing the first UAV to move to a different location.

10. The method of claim 1 , wherein instructing the first UAV to undock from the docking terminal comprises instructing the first UAV to change to a different docking terminal at the UAV charging station.

11. The method of claim 1 , wherein instructing the first UAV to undock from the docking terminal comprises instructing the first UAV to remain at the UAV charging station for a battery swap.

12. The method of claim 1 , wherein determining the priority of the second UAV is in response to the received docking requests from the UAVs including a docking request from the second UAV while the first UAV occupies the UAV charging station.

13. An unmanned aerial vehicle (UAV) charging station comprising:
a docking terminal including a charger configured to charge UAVs;
a transceiver configured to communicate with one or more UAVs; and
a processor coupled to the charger and the transceiver, wherein the processor is configured with processor-executable instructions to:
receive docking requests from UAVs;
determine a priority of a first UAV and a second UAV for using the docking terminal based on an available power level of each of the first and second UAVs; and
instruct the first UAV to undock from the docking terminal in response to determining that the second UAV has a higher priority.

14. The UAV charging station of claim 13 , wherein the processor is further configured with the processor-executable instructions to:
establish a communication link between the UAV charging station and the second UAV; and
receive, via the transceiver, the available power level and a UAV ranking from the second UAV;
wherein the processor is further configured to determine the priority of the first UAV and of the second UAV for using the docking terminal by weighing the available power level and the UAV ranking of each of the first and second UAVs.

15. The UAV charging station of claim 14 , wherein the processor is further configured with the processor-executable instructions to determine the priority of the first UAV and of the second UAV for using the docking terminal by weighing the available power level more heavily than the UAV ranking in response to the available power level of either the first or second UAVs being below a predetermined low threshold.

16. The UAV charging station of claim 14 , wherein the processor is further configured with the processor-executable instructions to determine the priority of the first UAV and of the second UAV for using the docking terminal by giving the UAV ranking no weighting in response to the available power level of either the first or second UAVs being below a predetermined critical threshold.

17. The UAV charging station of claim 14 , wherein the processor is further configured with the processor-executable instructions to determine the priority of the first UAV and of the second UAV for using the docking terminal by giving the available power level no weighting in response to the UAV ranking of either the first or second UAVs being above a predetermined ranking.

18. The UAV charging station of claim 13 , wherein one or more of the docking requests includes information selected from a group consisting of UAV identification, UAV authentication information, UAV ranking, the available power level, and how long the second UAV has been waiting to dock at the UAV charging station.

19. The UAV charging station of claim 13 , wherein the processor is further configured with the processor-executable instructions to include information about another charging station when instructing the first UAV to undock from the docking terminal.

20. The UAV charging station of claim 13 , wherein the processor is further configured with the processor-executable instructions to authorize the first UAV to remain at the UAV charging station but not in the docking terminal when instructing the first UAV to undock from the docking terminal.

21. The UAV charging station of claim 13 , wherein the processor is further configured with the processor-executable instructions to instruct the first UAV to change to a different docking terminal at the UAV charging station when instructing the first UAV to undock from the docking terminal.

22. The UAV charging station of claim 13 , wherein the processor is further configured with the processor-executable instructions to instruct the first UAV to remain at the UAV charging station for a battery
