Abstract
A position tracking system and a method thereof are provided. In the system, a power transmitting unit (PTU) provides power to a power receiving unit (PRU). The PRU chooses one of the PTUs adaptively to receive power, and broadcasts a broadcast information via a corresponding Bluetooth link. Three PTUs receive the broadcast information to obtain three pieces of position information respectively corresponding to the PRU respectively, and a position of the PRU is determined based on the position information of the three PTUs. Accordingly, positioning is implemented in the wireless charging technique by modifying software design.
Claims12
A position tracking method, adapted to determine position of a power receiving unit (PRU) via a plurality of power transmitting units (PTUs), wherein the PTUs transmit power to the PRU based on a magnetic resonance (MR) technology, the position tracking method comprising:
- adaptively choosing, by the PRU, one of the PTUs to receive power through the MR technology, and broadcasting broadcast information via a corresponding wireless communication link with Bluetooth and the MR technology;
- receiving, by three of the PTUs, the broadcast information, and respectively obtaining three pieces of position information with respect to the PRU according to the broadcast information received by the three PTUs;
- and
- determining a position of the PRU based on the three pieces of pieces of position information with respect to the PRU of the three PTUs.
A position tracking system, comprising:
- a plurality of power transmitting units (PTUs), transmitting power based on a magnetic resonance (MR) technology;
- and
- a power receiving unit (PRU), adaptively choosing one of the PTUs to receive power through the MR technology and broadcasting broadcast information via a wireless communication link with Bluetooth and the MR technology, wherein three of the PTUs respectively receive the broadcast information to obtain three pieces of position information with respect to the PRU according to the broadcast information received by the three PTUs, and a position of the PRU is obtained based on the three pieces of position information with respect to the PRU of the three PTUs.
