Description
The present invention relates to a non-contact charging system and method for an unmanned aerial vehicle.
Today, video surveillance systems using cameras are used in various fields such as transportation, transportation, theft and fire. Video surveillance system is divided into indoor and outdoor environment. Since most cameras installed in the outdoor environment are fixed in position and height, there are limitations in acquiring effective image information due to the smooth acquisition of image information of the moving objects and the environmental factors of the feature information.
In order to overcome these problems, research and development of a technology to overcome limitations of position and height and to shoot a desired area by installing a camera on an unmanned aerial vehicle (UAV) .
The unmanned aerial vehicle consumes a lot of power to shoot images while flying at high speed. Generally, the unmanned aerial vehicle is powered by the built-in battery, and the battery must be charged or replaced when the battery is low. In this case, the manager instructs the landing of the unmanned air vehicle in flight to charge or replace the battery of the unmanned air vehicle, which is inefficient and inconvenient.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a non-contact charging system and method of an unmanned aerial vehicle in which an unmanned aerial vehicle can autonomously charge a battery.
According to an embodiment of the present invention, a non-contact charging system of an unmanned aerial vehicle is provided. The non-contact charging system of the unmanned aerial vehicle includes a battery mounted on the unmanned aerial vehicle to supply electric power, at least one receiving coil connected to the battery, and at least one And a charging station for transmitting the AC power to the transmission coil, wherein the charging station includes a base board including the at least one transmission coil, and a side surface for protecting the base board, And an upper surface portion of the outer frame forms a groove portion corresponding to a position of the at least one transmission coil.
The groove portion may have a narrower groove diameter as it approaches the corresponding transmission coil from the upper surface portion.
The groove may be an inverted cone or an inverted polygonal cone.
The charging station may further include an inverter for converting direct current power into the alternating current power, and at least one capacitor connected between the inverter and the at least one transmission coil.
Wherein the at least one receiving coil is located at one end of each of the at least one leg and connected to the battery through an inner wire of the at least one leg, .
The charging station may be mounted on the roof of a vehicle or a building.
According to another embodiment of the present invention, a non-contact charging method of an unmanned aerial vehicle is provided. A method for non-contact charging of an unmanned aerial vehicle, comprising the steps of: autonomously landing at a charging station, and receiving three-phase alternating current power from the charging station via resonance between the three transmitting coils of the charging station and the three receiving coils of the unmanned air vehicle Wherein the charging station includes a base board including the three transmission coils, and an outer frame having a side surface for protecting the base board and an upper surface portion, The groove is formed so that three legs of the unmanned aerial vehicle are respectively inserted corresponding to the positions of the three transmission coils.
The landing step may include comparing the remaining power of the battery with a threshold value, searching the charging station for landing based on the position information of the unmanned air vehicle when the remaining power of the battery is smaller than the threshold value, And autonomously landing at a charging station.
According to the embodiments of the present invention, since the unmanned aerial vehicle can be autonomously charged, the long term mission can be efficiently performed. In addition, efficient operation of unmanned aerial vehicles is possible, and new unmanned aerial vehicles can be created with efficient UAV services.
