WIRELESS SENSOR NETWORK NODE POWER SUPPLY DEVICE Russian patent published in 2023 - IPC G01R29/00 G01R31/36 

FIELD: electronic equipment.

SUBSTANCE: invention relates to the field of power supply of electronic equipment and can be used to recharge batteries in elements of wireless sensor networks (WSN). The power supply device of the WSN node includes a WSN node, a solar battery, a first controlled switch, a monitoring and control unit, a storage battery and a second controlled switch, where the output of the solar battery is connected to the first input of the first controlled switch, the first output of which is connected to the input of the WSN node, and the second input and output are connected to the second output and the first input of the monitoring and control unit, the first output of which is connected to the battery battery, and the third output - to the first input of the second controlled switch, the second input of which is connected to the storage battery, and the output - to the input of the BSS node. At the same time, a third controlled switch and a rectone unit are introduced into its composition, the output of which is connected to the second input of the third controlled switch, the first input of which is connected to the fourth output of the monitoring and control unit, and the output is connected to the storage battery.

EFFECT: ensuring reliable power supply of the WSS node due to the possibility of round-the-clock recharging of the battery with the help of a charger delivered to it by means of an unmanned aerial vehicle at a distance at which the necessary wireless electromagnetic effect of the charger on the battery of the WSN unit is achieved.
