Abstract

The invention discloses an interaction method for a receiving end and a transmitting end in a radiation type wireless electrical energy transmission system. The method comprises steps that, an interaction process of information and energy for the receiving end and the transmitting end is defined, initiation, establishment and ending of charging connection can be realized through wireless communication at the receiving end and the transmitting end, compared with the electromagnetic inductance and magnetic resonance technology, the radiation type charging technology has longer transmission distance and better convenience and has great research values and application prospects, especially for the wireless sensing network, moreover, wireless charging protocol standardization based on the radiation type wireless electrical transmission technology is not only necessary in function, but also is inevitable requirement for industrial standardization.

Description

technical field [0001] The present invention relates to the technical field of protocol design for wireless power transmission, in particular to an interaction method between a receiving end and a transmitting end in a radiative wireless power transmission system. Background technique [0002] Wireless power transfer (Wireless Power Transfer, WPT) refers to an energy transfer method 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. 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 world. How to effectively...
