For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0060] An embodiment of the present invention provides a wireless charging system, which implements firmware update of the wireless charger through wireless communication (amplitude shift keying communication within the wireless charging band) when the wireless charger is not provided with a firmware upgrade interface.

[0061] The wireless charging system includes a wireless charging receiver and a wireless charger, and the wireless charging receiver and the wireless charger exchange data based on an amplitude shift keying communication packet (also called an ASK communication packet) in the wireless charging band. The wireless charging receiver can be, but is not limited to, a tablet, a mobile phone, a smart watch, etc.

[0062] The wireless charging receiving end can receive the target firmware information of the target version and the firmware upgrade data packet of the target version transmitted by the server.

[0063] When the wireless charging receiving terminal activates the wireless charging function and is placed in a charging area corresponding to the wireless charger, the wireless charging receiving terminal is used to send an upgrade command to the wireless charger, wherein the upgrade command includes target firmware information of the target version.

[0064] The wireless charger is used to determine whether the current firmware information is consistent with the target firmware information.

[0065] If they are consistent, it means that the current version corresponding to the current firmware information has been updated and upgraded, and no further update is required. The wireless charger is used to feedback the second type of status message to the wireless charging receiving end. At this time, the wireless charging system normally enters the wireless charging power transmission mode. If they are consistent, the firmware version needs to be updated.

[0066] When the current firmware information is inconsistent with the target firmware information, the wireless charger is used to feed back a first type of status message to the wireless charging receiving end.

[0067] In an optional implementation, the upgrade command also includes target charger identification information. When the target charger identification information in the upgrade command is consistent with the local device, and the current firmware information is inconsistent with the target firmware information, the wireless charger is used to feedback the first type of status message to the wireless charging receiving end. By adding the target charger identification information in the upgrade command, a directional update or directional repair can be achieved.

[0068] The wireless charging receiving end is used to send an offset address query request to the wireless charger when obtaining the first type of status message.

[0069] The wireless charger is used to feedback the current offset address to the wireless charging receiving end after obtaining the offset address query request, wherein the current offset address represents the offset address of the last byte in the firmware upgrade data packet of the target version last written in the wireless charger.

[0070] During the wireless charging process, the user may move the wireless charging receiver outside the charging area of ​​the wireless charger or the wireless charger may lose power, which may affect the transmission of the target version of the firmware upgrade data packet between the wireless charging receiver and the wireless charger. As a result, the wireless charger fails to receive the complete firmware upgrade data packet of the target version. By recording and feeding back the current offset address, the target version of the firmware upgrade data packet can be transmitted from the current offset address after the wireless charging receiver is reconnected, avoiding repeated transmission and improving the efficiency of firmware updates.

[0071] If the wireless charger has not previously stored a firmware upgrade data packet of the target version, the current offset address is 0.

[0072] In an optional implementation, in the wireless charging system, a private ASK packet may be defined based on the Qi protocol extension, such as a target-type ASK packet. The firmware upgrade data packet transmitted by the wireless charging receiver to the wireless charger is a target-type ASK packet.

[0073] The wireless charging receiving end is used to transmit the firmware upgrade data packet after the current offset address to the wireless charger to complete the wireless charger firmware update.

[0074] The wireless charging system provided in the embodiment of the present invention implements firmware updates for wireless chargers based on the amplitude shift keying communication packet in the wireless charging band, realizes senseless updates during the wireless charging process, and does not need to update the firmware of the wireless charger through the firmware upgrade interface, thereby improving the convenience of updates. By recording and feeding back the current offset address, the firmware upgrade data packet of the target version is continuously transmitted from the current offset address after the wireless charging receiving end is reconnected, avoiding repeated transmissions and improving the efficiency of firmware updates.

[0075] In an optional embodiment, the wireless charger is used to write the received firmware upgrade data packet into the first storage interval when receiving the firmware upgrade data packet transmitted by the wireless charging receiving end, and update the current offset address after the last byte of the firmware upgrade data packet is written into the first storage interval.

[0076] In an optional implementation, the firmware upgrade data packet carries a corresponding target offset address, wherein the target offset address is the offset address of the first byte in the expected firmware upgrade data packet.

[0077] The wireless charger is used to verify whether the target offset address matches the current offset address.

[0078] By determining whether the target offset address matches the current offset address, data packet loss can be avoided and the correctness of data transmission can be guaranteed.

[0079] If a match is found, the wireless charger is configured to write the received firmware upgrade data packet into the first storage interval, and update the current offset address after the last byte of the firmware upgrade data packet is written into the first storage interval.

[0080] In the case of a match, the wireless charger can also feed back a match success message to the wireless charging receiving end so that it can continue to send the remaining firmware upgrade data packets corresponding to the target version.

[0081] If there is no match, the wireless charger is used to send a correction request to the wireless charging receiving end, where the correction request includes the current offset address.

[0082] After receiving the correction request, the wireless charging receiving end can transmit the firmware upgrade data packet after the current offset address to the wireless charger according to the current offset address in order to complete the firmware update of the wireless charger.

[0083] In an optional implementation, the wireless charger is used to modify the status flag to an upgradeable state after writing all firmware upgrade data packets of the target version into the first storage interval.

[0084] The wireless charger is used to copy the firmware upgrade data packet in the first storage interval to the second storage interval if it is determined that the status flag is in an upgradeable state after the reset is completed.

[0085] The reset here may be a self-reset after the wireless charging receiving end is moved out of the charging area corresponding to the wireless charger or a power-off reset of the wireless charger.

[0086] If the status flag is not in an upgradeable state, the wireless charger runs the firmware program corresponding to the current version in the second storage interval.

[0087] After the copying is completed, the wireless charger is used to run the firmware upgrade data package corresponding to the target version in the second storage interval, thereby completing the wireless charger firmware update.

[0088] In an optional implementation, the wireless charger is used to verify whether the firmware upgrade data packet in the second storage interval is complete.

[0089] If complete, the wireless charger is used to run the firmware upgrade data package corresponding to the target version in the second storage interval.

[0090] If it is incomplete, the wireless charger performs feedback processing (feedback to the wireless charging receiving end to obtain a complete firmware upgrade data packet corresponding to the target version), and the wireless charger runs the firmware program corresponding to the current version in the second storage interval.
