The present invention pertains to a technique for supplying power to an object in midair, and more specifically, to a ground-level power supply system for a small unmanned aerial robot to continuously supply power as a power source for the small unmanned aerial robot to stay in midair a long time, to operate a camera, a communication relay, and a lighting device, and to hover in midair with directional change and the like. The ground-level power supply system includes: the small unmanned aerial robot including a propeller, a monitoring camera, a communication relay, a motor/controller, a voltage booster/charger, a light-emitting diode (LED) lighting device, a battery power source, and a wind direction balancing device; and a ground-level power supply for supplying power from the ground, wherein the ground-level power supply includes: a cable formed by a flexible material, wherein the thickness of inner wirings in the cable varies according to the body size or the use of the small unmanned aerial robot; a wiring winding device functioning as a reel for winding and unwinding the cable; a fixing device for fixing the cable to the wiring winding device; a fixing base installed with a weight that changes according to the size of the small unmanned aerial robot to fix and pull the small unmanned aerial robot when the fixing base is installed on the ground; an outlet formed to receive alternate current (AC) or direct current (DC) power from the outside; and a power connection line for supplying power to the small unmanned aerial robot via the cable which supplies the power by supplying the AC or DC power received from the outlet to a cable terminal of the wiring winding device. |
