Device and method for detecting foreign objects in a wireless power transmission system

Abstract

The invention discloses a device and a method for detecting a foreign object in a wireless power transmission system. The device comprises a chassis, a display, an operation panel, bearing installation grooves, a cover plate, an anti-collision block, a connecting rotating shaft, fixed bearings, a diffuser, a light box, support plates, coil springs, a signal lamp, clamping blocks, clamping slots, aswitch, a detection box, waterproof membranes, a mounting base plate, a power detection module, a power demand module, a power receiving module, an information processing module, an information display module, a heat radiation plate, main and standby power supplies, a cavity, an insulation board, a heat dissipation hole, a detection board, an induction coil, a mounting and fixing board, a bucklegroove, a slide plate, a connecting frame, a fixed shaft, a roller and a wear-resisting plate. Two sides of one end of the chassis are provided with the bearing installation grooves which are internally provided with the fixed bearings. The device has the advantages of small structure, convenient carrying, firm fixation and a good dustproof effect, and foreign object detection can be performed onthe wireless power transmission system.

Description

technical field [0001] The invention relates to the technical field of wireless power transmission systems, in particular to a device and method for detecting foreign objects in a wireless power transmission system. Background technique [0002] Wireless power transmission uses radio means to convert the power produced by the power plant into radio waves and send them out, and then collect the radio waves through a specific receiving device and convert them into electricity of corresponding current and voltage for people to use; in wireless power transmission During the process, if there is a foreign object, it will interfere with the effect of wireless power transmission. The equipment for detecting foreign objects in the prior art has a complex structure, a huge volume, poor detection effect, very inconvenient to use, and does not have the function of prompting, and , after use, it does not have the function of dust prevention, and it is easy to accumulate dust, which affe...

[0002] Wireless power transmission uses radio means to convert the power produced by the power plant into radio waves and send them out, and then collect the radio waves through a specific receiving device and convert them into electricity of corresponding current and voltage for people to use; in wireless power transmission During the process, if there is a foreign object, it will interfere with the effect of wireless power transmission. The equipment for detecting foreign objects in the prior art has a complex structure, a huge volume, poor detection effect, very inconvenient to use, and does not have the function of prompting, and , after use, it does not have the function of dust prevention, and it is easy to accumulate dust, which affects the detection effect. Therefore, it is necessary to design a device and method for detecting foreign objects in a wireless power transmission system
