WIRELESS SENSOR NETWORK NODAL ELEMENT ACCUMULATOR CHARGING DEVICE Russian patent published in 2024 - IPC G01R29/08 B64U101/66 H02J50/20 

FIELD: power supply of radioelectronic equipment.

SUBSTANCE: invention can be used to provide uninterrupted power supply of wireless sensor network (WSN) elements. Proposed solution consists in application of cone-shaped cover of sensor element (SE) as guide during mutual displacement of windings forming transformer, through which electric energy is supplied to the sensor element. Essence of the proposed solution consists in the fact that the cone-shaped cover and the winding provide their approach and mutual fixation of the transformer windings, thereby increasing its efficiency. Device provides a transformer mode of power transmission from an unmanned aerial vehicle (UAV) to a SE. In working condition, winding having the shape of a truncated cone is put on the cover from above. Winding can move relative to the UAV and the cover. By moving the winding, it is brought into engagement with the upper part of the conical cover, and then the winding is lowered until this cover is completely inserted into it, which ensures reliable transformer coupling.

EFFECT: provision of reliable power supply of the unit of WSN and reduction of time spent on recharging of its accumulators.
