Abstract
Each wireless charging device of the wireless charging system has a Bluetooth module for detecting signal strength between the wireless charging device and an electronic device. The signal strength information is shared among the wireless charging devices by their data transceiver units. An analysis module of each wireless charging device automatically determines one wireless charging device having the best connection, and a decision module of the determined wireless charging device transmits a charging permit to the electronic device. Cross connection of the electronic device to multiple wireless charging devices is therefore avoided.
Claims10
A wireless charging system, comprising a plurality of wireless charging devices, wherein each wireless charging device comprises
- a Bluetooth module for wirelessly linking at least an electronic device;
- a signal detection module for detecting a signal strength between the Bluetooth module and the electronic device;
- a data transceiver unit electrically connected to the signal detection module for transmitting at least a broadcast message to all other wireless charging devices;
- an analysis module electrically connected to the data transceiver unit for determining one of the wireless charging devices as a selected wireless charging device as having a best connection with the electronic device based on the signal strength and the broadcast messages received;
- and
- a decision module electrically connected to the analysis module for transmitting a charging permit to the electronic device if the decision module is inside the selected wireless charging device.
A wireless charging method, comprising:
- (a) providing a Bluetooth module in a wireless charging device;
- (b) detecting a signal strength between the Bluetooth module and an electronic device by a signal detection module of the wireless charging device;
- (c) transmitting a broadcast message from a data transceiver unit of the wireless charging device to at least one other wireless charging device;
- (d) determining if the wireless charging device has a best connection to the electronic device by an analysis module of the wireless charging device according the signal strengths from the signal detection module and from the broadcast messages received;
- and
- (e) transmitting a charging permit to the electronic device if a decision module of the wireless charging device determines that it has the best connection with the electronic device.
