Zigbee networks visible light positioning wireless charging system and method

Abstract

The invention discloses a Zigbee networks visible light positioning wireless charging system and a method. The system includes a wireless charging device and a Zigbee network node; the wireless charging device and the Zigbee network node communicate with each other through a Zigbee protocol; the wireless charging device includes a wireless charging module and a light source detection module; and the Zigbee network node comprises a gateway node, a coordinator and a terminal node, wherein the coordinator is used for coordinating the communication between the gateway node and the terminal node. As for a situation that wireless charging does not require accurate positioning, the invention provides a simple and convenient visible light positioning scheme. The visible light positioning scheme has the advantages of high positioning efficiency and simple computation, and can greatly improve wireless charging efficiency.

Description

technical field [0001] The invention relates to the field of sensor networks and wireless charging, in particular to a Zigbee network visible light positioning wireless charging system and method. Background technique [0002] Wireless charging, also known as inductive charging, non-contact inductive charging, uses near-field induction, that is, inductive coupling, to transmit energy from a power supply device (charger) to a device that uses electricity, and the device uses the received energy to The battery is charged and simultaneously used for its own operation. Since energy is transmitted between the charger and the power-consuming device through inductive coupling, there is no need for wires to connect the two, so that both the charger and the power-consuming device can have no exposed conductive contacts. [0003] Due to the complex terrain and inconvenient wiring in environments such as mines, it is best to use wireless charging. If remote wireless charging does not...

Problems solved by technology

If remote wireless charging does not perform positioning but uses broadcasting to charge, the efficiency will be very low, and it will cause a large amount of electromagnetic leakage, causing electromagnetic interference and other problems to surrounding equipment.

Conventional positioning uses GPS positioning, ultrasonic positioning, etc. These positioning devices generally consume a lot of power, and the algorithm is more complicated, which increases the power consumption of the processor and is not conducive to the continuous operation of the charging system.
