Apparatus and method for anti-collision in wireless power transmission
First Claim
1. An anti-collision method in wireless power transmission, the method comprising:
- transmitting, from a source device to a target device, an access standard instruction comprising an access standard that is used to identify the target device;
transmitting, to the target device, a call parameter used to detect an identification (ID) of the target device, the call parameter being generated based on the access standard; and
assigning, to the target device, a control ID based on a response signal that the target device transmits in response to receiving the call parameter.

Abstract
Provided is an anti-collision method and apparatus used during wireless power transmission with respect to a plurality of target devices. According to one general aspect, an anti-collision method in wireless power transmission may include: transmitting, from a source device to one or more target devices, an access standard instruction including an access standard that is used for identifying the target devices; transmitting, to the one or more target devices, a call parameter used to detect identifications (IDs) of the target devices, generated based on the access standard; and assigning, to the one or more target devices, control IDs based on response signals that the one or more target devices transmits in response to the call parameter.

15. An anti-collision method in wireless power transmission, the method comprising:
-
transmitting, from a source device to one or more target devices in a wireless power transmission area, an access standard instruction including an access standard to be used for identifying the one or more target devices; transmitting, to the one or more target devices, a call parameter generated based on a value set in a call argument field; determining whether at least one response signal is received from the one or more target devices in response to the call parameter; determining whether overlapping identifications (IDs) exist among IDs of the one or more target devices based on a number of the at least one response signal, when the at least one response signal is received; and assigning a control ID to a target device that transmits a response signal, when the number of the at least one response signal is one and the overlapping IDs are absent among the IDs of the one or more target devices. - View Dependent Claims (16, 17, 18)

19. An anti-collision method in wireless power transmission, the method comprising:
-
receiving an access standard instruction including an access standard to be used for identifying one or more target devices; generating an ID of a target device, based on values set in a reference field, call argument field, and a movement argument field included in the access standard instruction; receiving a call parameter generated based on the value set in the call argument field; comparing the ID and the call parameter; transmitting, to a source device, a response signal in response to the call parameter, when the ID has the same value as the call parameter; and assigning, from the source device, a control ID. - View Dependent Claims (20, 21)

22. An anti-collision apparatus in wireless power transmission, the apparatus comprising:
-
a communication unit configured to transmit, from a source device to a target device sensed during a predetermined time, a call parameter and an access standard instruction including an access standard to be used for identifying the target device, and to receive a response signal from the target device in response to receiving the call parameter; and a controller configured to determine the call parameter based on the access standard instruction, and to assign a control identification (ID) to the target device, based on the response signal from the target device in response to the call parameter. - View Dependent Claims (23, 24, 28, 29)

25. An anti-collision apparatus in wireless power transmission, the apparatus comprising:
-
a target resonator configured to receive, from a source device, a wake-up power to be used for communication; a communication unit configured to receive an access standard instruction including an access standard to be used for identifying one or more target devices, a call parameter generated based on the access standard instruction, and a control ID to be used for identifying the one or more devices, and to transmit a response signal to the source device in response to the call parameter when an ID of a target device has the same value as the call parameter; and a controller configured to generate an ID of a target device, based on values set in a reference field included in the access standard instruction, a call argument field, and a movement argument field, and to determine whether the ID has the same value as the call parameter. - View Dependent Claims (26)
