Problems solved by technology

[0004] However, the current specifications generally focus on the case of only one power transmission unit, that is, there is one and only one energy transmitter (TX) in the system, and commercialized wireless charging devices are basically one-to-one wireless charging methods. And the charging distance is close to zero distance and basically fit, which requires a high degree of coupling between the transmitting end and the receiving end

Embodiment Construction

[0047] In combination with the specific content of the present invention, the purpose of the present invention is to implement a wireless charging solution with considerable efficiency and a certain distance (within 40 cm) for multiple devices, by solving the current control of the bottom transmitter and the energy path routing of the high layer to meet this requirement. The deployment of the system is mainly divided into four parts, such as figure 1 shown.

[0048] "TX circuit" means the transmitter circuit, we use a homogeneous transmitter coil made of a printed circuit board with a radius of 15 cm and an area of ​​0.0707 square meters. Each series circuit consisting of a TX coil and a high-frequency high-Q capacitor is powered by an amplified controllable sinusoidal signal. Since we use an AC-DC converter to obtain 24V DC, our system can be directly powered by commercial frequency AC. For more precise and better resonance, all components in our system are specially desig...

Abstract

The invention relates to an MIMO relay charging method based on magnetic resonance and DQN, and the method consists of four circuits: a TX circuit transmitting end circuit, a Relay circuit relay end circuit, an RX circuit receiving end circuit, a control circuit of a TX-relay controller transmitting end relay end, and the TX circuit transmitting end circuit, the Relay circuit relay end circuit, and the RX circuit receiving end circuit are all controlled by the control circuit of the TX-relay controller transmitting end relay end. According to the invention, the wireless charging distance is significantly improved, the wireless charging action range is increased, the wireless charging availability is enhanced, the positive influence on the application of wireless magnetic charging is achieved, and the development of wireless charging is facilitated.

Description

technical field [0001] The MIMO relay charging method based on magnetic resonance and DQN involved in the present invention belongs to the technical field of wireless charging. Background technique [0002] With the widespread use of hundreds of millions of smart devices in the crowd, the charging of these devices has become a very important research topic. In recent years, the Wireless Power Transmission system has been intensively studied, and a number of wireless charging devices have appeared on the market to solve the problem of repeated plugging and unplugging of smart devices to replenish power. Compared with traditional wired charging methods, the most obvious advantage of wireless charging is that there are no wires, which reduces safety risks and is conducive to product waterproof and dustproof design. [0003] At present, short-distance wireless power transmission systems are usually implemented in two ways, namely: Inductive Coupling (Inductive Coupling, or Magn...
