The invention discloses an automatic matching and communication control system and method between wireless charging devices based on waveform feature recognition and an electronic device, which are used for connecting any wireless charging transmitting terminal with a plurality of identical wireless charging devices in a venue. A wireless receiving terminal is connected, including the following steps: the transmitting terminal sends a broadcast signal with a first signal characteristic value; the receiving terminal samples the waveform of the received broadcast signal to obtain a second signal characteristic value; the receiving terminal converts the second signal characteristic value The value and the randomly generated private address are sent out; the transmitter judges whether the received second signal characteristic value is the same as the first signal characteristic value. If they are the same, the transmitter and the receiver communicate through the private address. If they are different, the data frame is discarded. . The identification and matching in wireless communication is achieved by identifying specific waveforms between the transmitting end and the receiving end, and the automatic matching communication between the transmitting end and the receiving end is realized in pure software, without adding hardware, which saves costs.
Description
technical field [0001] The invention relates to the technical field of wireless charging, in particular to an automatic matching and communication control system and method between wireless charging devices based on waveform feature identification, and an electronic device. Background technique [0002] The wireless charging system means that the wireless transmitting coil and the wireless receiving coil transmit energy through the magnetic field to realize the non-contact transmission of electric energy. [0003] With the development of technology, wireless charging devices are widely used. The wireless charging system is generally divided into a transmitter and a receiver. Because the two parties are non-contact when working, they can only exchange data by means of wireless communication. [0004] At present, many wireless charging devices use low-cost radio frequency communication modules to achieve communication, such as 433MHZ, 2.4GHZ communication modules. The radio...
