Embodiment Construction

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0048] Radiative wireless power transfer technology, compared with electromagnetic induction and magnetic resonance technology, has a longer transmission distance and better convenience, and has great research prospects and applications, especially for wireless sensor networks. This method mainly uses the microwave band for power transmission. Microwaves are electromagnetic waves with wavelengths between radio waves and infrared rays. Due to the h...

Abstract

The invention discloses an interactive process state defining and converting method a radiation type wireless electric energy transmission system. Establishment of a control protocol for the radiation type wireless electric energy transmission system satisfies a function requirement and furthermore promotes an industrial standard process. The invention provides a defining and converting triggering condition for five states which are required in a system interaction process for aiming at the radiation type wireless electric energy transmission system, so that a receiving end and a transmission end can realize wireless communication interaction and electric energy transmission according to a state switching process.

Description

technical field [0001] The invention relates to the technical field of protocol design for wireless power transmission, in particular to a method for defining and converting the state of an interactive process in a radiative wireless power transmission system. Background technique [0002] Wireless power transfer (wireless power transfer, WPT) refers to an energy transfer method of electric energy from a power source to a load without direct electrical contact. According to different transmission mechanisms, wireless energy transmission can be mainly divided into electromagnetic induction, magnetic field resonance, and radiation. Among them, the radiation type can be divided into radio wave mode, microwave mode, laser mode and ultrasonic mode. [0003] In the 21st century, human beings are faced with the major challenge of achieving sustainable economic and social development, and environmental and energy issues have increasingly become one of the prominent issues in the wo...
