Abstract

The purpose of the present invention relates to a network-based wireless power control method, and a device and a system therefor. A wireless power control method, in a wireless power transmission device which wirelessly transmits power to a wireless power reception device, according to a first embodiment of the present invention, comprises the steps of: transmitting a first signal via a first frequency band when a power source is applied; when a second signal corresponding to the first signal is received via a second frequency band, measuring the first reception sensitivity of the second signal; receiving second to n-th reception sensitivities corresponding to the second signal from at least one other wireless power transmission device connected via a network; and determining whether power has been wirelessly transmitted to the wireless power reception device, on the basis of the first to n-th reception sensitivities. As such, the present invention has an advantage of being capable ofmore effectively transmitting power wirelessly by using a wireless power transmission device connected via a network.

Description

technical field [0001] Embodiments relate to a network-based wireless power transmission technology, and more particularly, to a network-based wireless power control method and a device and system thereof, the method realizing mobile control through cooperation between network-connected wireless power transmission devices Seamless power transfer for wireless power receiving devices. Background technique [0002] Recently, with the rapid development of information and communication technology, a ubiquitous information society based on information and communication technology is being formed. [0003] In order for information communication devices to be connected anytime and anywhere, sensors equipped with computer chips with communication functions should be installed in all facilities throughout society. Therefore, the power supply of these devices or sensors is becoming a new challenge. In addition, with the rapid increase in the number of various types of mobile devices ...
