When the first electromagnetic coil 101 is energized and matched with the second electromagnetic coil 201, The wireless charging device 10 charges the device 20 to be charged. In the present embodiment, the number of the first electromagnetic coil 101 and the second electromagnetic coil 201 is one, which respectively includes a first iron core and a second iron core, and the first iron core and the second iron core A plurality of turns of wire are wound around the top. The device to be charged 20 is capable of generating a signal S1 to be authenticated and having a modulation module 21 for modulating the signal S1 to be authenticated into a south frequency signal S2 and controlling the electromagnetic coil 201 And the first electromagnetic coil 101 is transferred to the wireless charging device 10. In this embodiment, the to-be-authenticated signal S1 is a digital signal. The to-be-authenticated signal S1 is obtained by signal-modulating the specific identification code of the device to be charged 20, and the high-frequency signal S2 is a pulse signal having a certain periodic characteristic. Specifically, the device to be charged 0 20 is a mobile phone. The specific identification code is a serial number of the mobile phone.

The modulation module 21 uses QPSK (Quadature Phase Shift Keying) digital modulation method, QPSK is quadrature phase shift keying, and in the digital signal modulation mode, QPSK is currently the most commonly used digital signal modulation method, which has High spectrum utilization and strong anti-interference are also simple to implement on the circuit. The signal to be authenticated S1 can be converted into a frequency pulse signal after being modulated. When the wireless charging device 10 is powered on, the first electromagnetic coil 101 is energized by 6 201041264 to generate a power signal S3. In this embodiment, the wireless charging device -10 is electrically connected to an AC power source (not shown) via a wire 102. The power source * signal S3 is a 50 Hz AC signal. Before the wireless charging device 1 does not authenticate the device to be charged 20, the first electromagnetic coil 101 is a low current signal. The wireless charging device 1 includes a mixing module n, an analysis module 12, a comparison module 13, and an authentication module 14. The mixing module 11 is configured to mix the high frequency signal S2 and the power signal S3 into an identification signal S4. Since the high frequency signal 52 and the power signal S3 are periodic signals, the identification signal S4 also has a periodic variation characteristic.

The authentication module 14 is configured to authenticate the identification signal S4 according to the comparison module 13. Specifically, if the identification signal S4 is equal to the amplitude and the frequency in the preset signal value; the authentication is successful, and the wireless charging device 10 is triggered to charge the device to be charged 20; if the identification signal S4 If the amplitude or frequency in the preset signal value does not match, the authentication fails, and the wireless charging device 10 is not electrically connected to the device to be charged 20.

DC power signal nickname S3. At this time, the to-be-authenticated signal si to be charged device 2A is obtained by the first holding coil 1〇5 and the corresponding second holding coil 205, and the to-be-authenticated signal si is transmitted to the authentication module 14 for authentication. . When the authentication is successful, the primary coil 103 is triggered to increase the charging current and is electrically coupled to the secondary coil 203 to enable charging of the device to be charged. When one of the first holding coils 1〇5 and the second holding coils 2〇5 X is blocked, the other sets of the first holding coils 105 and the second holding coils 205 can be exchanged for authentication. As shown in FIG. 4, the wireless charging authentication method provided by the present invention is used in the wireless charging authentication system described in the above-mentioned 9 201041264, and the method includes the following steps: - (4) S401, the device to be charged modulates the signal to be authenticated into a high frequency The message number is transmitted to the wireless charging device. Step S403, the wireless charging device mixes the high frequency signal with the power signal in the first electromagnetic coil as an identification signal. Step S405, comparing the identification signal with the preset signal value, and determining whether the identification signal matches the preset signal value. If the identification signal 相 matches the preset signal value and the authentication is successful, step S4〇7 is executed to trigger the wireless charging device to charge the device to be charged. If the identification signal does not match the preset signal value and the authentication fails, step S4〇9 is performed, and the wireless charging device is disconnected from the device to be charged. In summary, the wireless charging authentication system and method of the present invention increases the authentication process of the device to be charged before the wireless charging device charges the device to be charged, and performs charging only after the authentication is successful, thereby being able to avoid the wireless charging device. The phenomenon of wasting power when it does not match the device to be charged occurs. It is to be understood that various other modifications and changes can be made by those skilled in the art in light of the technical scope of the invention, and all such changes and modifications are within the scope of the invention.
