FIG4 is a block diagram showing the components of a signal modulation and demodulation unit according to an embodiment of the present invention
As shown in FIG4, signal modulation and demodulation unit 3 is an interactive system of the wireless charging device and the electronic devices. Signal modulation and demodulation unit 3 includes multi-channel signal identification module 30, signal processing module 31, protocol module 32, and multi-channel signal transmission module 33 which are connected successively. Multi-channel signal identification module 30 demodulates multi-channel ASK signals simultaneously to realize the conversion from analog signal to digital signal. Signal processing module 31 is responsible for the routing management of the communication of multiple electronic devices, and encodes and encapsulates the digital signals of multi-channel signal identification module 30. The encapsulated signal is translated by protocol module 32 according to the QI standard or the PMA standard. Protocol module 32 passes the translated signal to control unit 2 for processing, and protocol module 32 transmits the control command signal from control unit 2 to multi-channel signal transmission module 33 according to the QI standard or the PMA standard. Multi-channel signal transmission module 33 simultaneously modulates the multi-channel signal according to the FSK mode and loads the modulated signal onto the specified coil of coil module unit 5.
