Embodiment Construction

[0018] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0019] Such as figure 1 As shown, it provides a schematic framework diagram of a preferred embodiment of the present invention. The energy transmitting coil can be a disk coil or a helical coil, and under the action of the transmitting control circuit, a non-sinusoidal current wave flows through it. There is good magnetic coupling between the magnetic field excited by the current wave of the energy transmitting coil and the energy receiving coil and the communication coil, such as figure 1 Indicated by the dotted arrow line. The energy receiving coil can be a disk coil or a helical coil, and its resonant frequency point is consistent with the fundamental current frequency point of the non-sinusoidal current wave in the energy transmitting coil to realize wireless energy transmission. The communication coil can be a disk coil or a helical coil, a...

Abstract

The invention discloses a layout method for coils of a wireless power supply and communication multiplexing system. The multiplexing system comprises a transmitting circuit, an energy transmitting coil, an energy receiving coil and a communication coil, wherein the resonant frequency point of the energy receiving coil is consistent to the fundamental wave signal frequency point in the energy transmitting coil; the resonant frequency point of the communication antenna is consistent to the harmonic signal frequency point in the energy transmitting coil; in the aspect of space layout, the axle wire of the communication coil is perpendicular to the tangent line of the energy receiving coil; and the energy receiving coil and the communication coil are arranged on the same plane. According to the layout method, magnetic shielding to an information channel is not required; communication with relatively high signal to noise ratio can be obtained; the size and the cost of the system are greatly lowered; and therefore, the layout method has a bright application prospect.

Description

technical field [0001] The invention designs a coil layout method of a wireless power supply and communication multiplexing system, belonging to the field of wireless power supply and communication. Background technique [0002] With the popularity of intelligent autonomous navigation equipment and portable electronic equipment, equipment that directly uses wireless power supply technology has been widely used in all aspects of people's production and life. [0003] As electronic devices become more and more intelligent, the energy consumption required is also increasing, so they need to be constantly replenished and charged. While charging, it is also necessary to communicate with the device to further improve the level of intelligence. However, considering the size and cost, there are certain restrictions on using wireless modules such as Bluetooth and GSM modules to build communication sources independently. For low-cost, small-volume wireless charging devices, issues s...
