Embodiment Construction

[0030] The specific implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the embodiments described in the specific implementation are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The present invention provides a wireless charging system and a charging method. Different from the traditional wireless charging system, the wireless charging system provided by the present invention has a living body detection function, which can detect whether there is a living thing between the coil at the transmitting end and the coil at the receiving end; and Different from the traditional wireless charging method, the wireless charging m...

Abstract

The invention discloses a wireless charging system with an in vivo detection function. The wireless charging system comprises a transmitting terminal metal plate which is arranged close to or clings to a transmitting terminal coil, wherein the transmitting terminal metal plate is connected with an oscillating circuit and a capacitive digital converter in sequence; a transmitting terminal MCU (Microprogrammed Control Unit) is connected with the capacitive digital converter, and is used for acquiring a digital signal of the capacitive digital converter and generating a control signal of the system according to the acquired digital signal. A wireless electric energy transmission method with the in vivo detection function comprises the following steps: setting a capacitance threshold value at the transmitting terminal CPU; judging a relation between capacitance output by the capacitive digital converter and the capacitance threshold value in order judge whether a living body enters the wireless electric energy transmission system or not. By adopting the system and the method, the presence of living beings in magnetic fields of the transmission terminal coil and a receiving terminal coil can be recognized, and the security of the wireless electric energy transmission system can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and relates to a wireless charging system and a charging method, specifically, a wireless charging system and a charging method with a living body detection function. Background technique [0002] Wireless power transmission is a technology for power transmission through space electromagnetic field coupling. Its main advantages are that it does not need to be plugged and unplugged, and it is simple and convenient to use; it does not generate electric sparks and can be used in flammable and explosive industrial environments; it can be used in Energy transmission in water can be applied to underwater applications such as marine equipment. [0003] The wireless power transmission system mainly includes two parts, one is energy transmission, through power conversion, the power is wirelessly transmitted from the transmitter to the receiver; the other part is communication control, which is m...
