Embodiment 1
[0054] Please refer to figure 1 , Embodiment 1 of the present invention is:
[0055] A wireless charging standby detection method, comprising the following processing steps:
[0056] S1. Obtain the number of charging pulses for the detection capacitor.
[0057] S2. Determine whether to send a Ping signal according to the number of charging pulses. Step S2 is specifically: judging whether the number of charging pulses exceeds a preset value; if yes, sending out a Ping signal; otherwise, not sending out a Ping signal. In this embodiment, the size of the preset value can be set as required.
[0058] S3. After the Ping signal is sent, it is judged whether the power feedback information from the charging receiver is received; if yes, execute step S4; if not, enter the standby state. The power feedback information includes power demand information and actual power information.
[0059] S4. Turn on the charging circuit.
Embodiment 2
[0060] Please refer to figure 2 , the second embodiment of the present invention is:
[0061] A wireless charging terminal 100 corresponds to the method in Embodiment 1.
[0062] The wireless charging terminal includes a processor 1, a memory 2, and a computer program stored in the memory 2 and operable on the processor 1, and the processor 1 implements the following steps when executing the computer program:
[0063] Obtain the number of charging pulses for the detection capacitor;
[0064] Judging whether a Ping signal needs to be sent according to the number of charging pulses;
[0065] After the Ping signal is sent, it is judged whether to receive the power feedback information of the charging receiver; the power feedback information includes power demand information and actual power information;
[0066] If so, turn on the charging circuit.
[0067] Further, the judging whether a Ping signal needs to be sent according to the number of charging pulses is specifically:...
Embodiment 3
[0072] Please refer to image 3 and Figure 4 , Embodiment three of the present invention is:
[0073]A wireless charging terminal is a specific application scenario of the above-mentioned embodiment. The wireless charging terminal includes an upper cover 3, a lower case 4, and a charging component 5. The charging component 5 is arranged on the upper cover 3 and the lower cover. Between the shells 4, a detection capacitor 6 is provided on the upper cover plate 3. The detection capacitor 6 can be laser-engraved to form a comb-shaped capacitor circuit, and then chemically plated or electroplated metal on the engraved circuit to complete the production of the capacitor. When there is a foreign object on the two polar plates of the detection capacitor 6 or there is a charging receiving end, the MCU of the charging component 5 charges the detection capacitor 6 through high-frequency pulses, and records the number of charging pulses when the charging is completed through the intern...
