Channel preemption method for electric energy wireless transmission system and power supply equipment

Abstract

The invention relates to a channel preemption method for an electric energy wireless transmission system and is applied to the power supply equipment. The method comprises steps that when the corresponding load equipment is detected to need power supply, a self preemption message is broadcasted in a matching channel, and a preemption message of other power supply equipment can be monitored from the matching channel; the preemption message contains preemption priority of the power supply equipment which broadcasts the preemption message; if the self preemption priority is higher than that of other power supply equipment, withdrawal from the matching channel is actuated after a matching message of the corresponding load equipment is received, and entry into a work channel is actuated; if the preemption priority of other power supply equipment is higher than the self preemption priority of the present power supply equipment, withdrawal from the matching channel is actuated, and broadcast and monitoring are re-actuated in the matching channel after the largest preemption time arrives. Through broadcasting the preemption message, power supply sequence of the power supply equipment is automatically ordered, so a problem of crossing mismatching caused by matching information reception errors generated among multiple sets of wireless power supply equipment can be solved.

Description

technical field [0001] The invention relates to the technical field of wireless power transmission, in particular to a channel preemption method and power supply equipment of 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 current equipment is used as a set, that is, the power supply equipment and the load equipment are in one-to-one correspondence, but the pairing operation needs to be completed manually, for example, the power supply equipment / load equipment enters the pairing mode through key operation, and another equipment searches for the equipment in the communication network After th...
