Embodiment Construction
[0016] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.
[0017] In order to facilitate a quicker understanding of the illustrative embodiments of the invention, a brief description of the main idea of the invention is first given here.
[0018] In order to prevent multiple power supply devices from pairing with the load device on the pairing channel at the same time, it is easy to cause poor communication in the pairing channel, and the pairing operation cannot be completed normally; For the problem of transmission failure, each power supply device in the present invention broadcasts its ow...

The invention discloses a power supply authority preempting method for an electric energy wireless transmission system, and power supply equipment, wherein the method is used for the power supply equipment. The method comprises the steps: broadcasting a power supply authority preempting message for preempting load equipment, and detecting the preempting messages broadcast by other power supply equipment, wherein the preempting message comprises a preempting priority of the power supply equipment broadcasting the preempting message; enabling the preempting priority of the equipment to be compared with the preempting priority of other power supply equipment; determining that the equipment obtains the power supply authority of the load equipment if the preempting priority of the equipment is the highest, or else, quitting the preempting of the power supply authority of the load equipment, and stopping the broadcasting and detection of the preempting message. Through the broadcasting of the preempting message, the method achieves the automatic screening of the unique power supply equipment for supplying electric energy to the load equipment, and prevents a condition that the load equipment is provided with a plurality of pieces of power supply equipment from causing an electric energy transmission failure. Moreover, the method enables a screening program to be automatically executed through the power supply equipment, and simplifies the complexity of load equipment.
Description
technical field [0001] The present invention relates to the technical field of wireless power transmission, in particular to a power supply authorization preemption method and power supply equipment for a wireless power transmission system. Background technique [0002] Wireless power supply / charging technology is to wirelessly transmit power through coupling coils. This power transmission method does not require wires / cables. Compared with the traditional power supply using wires / cables, it avoids cumbersome lines and reduces the footprint of equipment. , making it more convenient for users to place and use the device. [0003] The existing equipment needs to be paired between the power supply equipment and the load equipment before use. The pairing operation needs to be completed manually by the user or the staff. After searching the device in the network, access the device, complete the pairing, and send the identification of the load device and the required power supply...
