Non-stop drone operations enabled by overhead power line recharging
Researchers propose an autonomous drone system, drawing energy from transmission cables, enabling continuous operation.
A magnetic manipulating circuit is also implemented to sustain the holding force and harvest energy, intelligently adapting to power line current levels and battery conditions. To provide enough holding force and to recharge the batteries, a control circuit modifies the magnetic field within a split-core current transformer once a passively actuated gripping mechanism grasps the power line wire during landing. A passively actuated gripping mechanism grasps the powerline cable during landing after which a control circuit regulates the magnetic field inside a split-core current transformer to provide sufficient holding force as well as battery recharging.
