GND is ground; VBUS is the main charging power supply; TX1+ and TX 1-are USB 3 first set of output communication signals; TX2+ and TX 2-are USB 3 second set of output communication signals; RX1+ and RX 1-are the USB 3 first set of received communication signals; RX2+ and RX 2-are USB 3 second set of received communication signals; d + and D-are the initial communication settings for receiving and outputting communication signals by the USB2 and also for charging; SBUs 1 and 2 are audio signals; VCONN is a power supply signal during charging and quick charging; CC1, CC2, and CC are fast charge request reply signals. During charging, no signal is received at the charging terminals TX1+, TX1-, TX2+, TX2-, RX1+, RX1-, RX2+, RX2-, SBU1 and SBU2, and no effect is caused; during charging, the D + and the D-of the receiving end firstly make initial communication setting of charging; then, the CC of the receiving end is connected to the CC1 or CC2 through the interface, the receiving end transmits the charging request, and the power supply receives the request and starts the charging service from VBUS and GND.

when the potential of a line connected with the power supply output port is higher than that of a reference line, the wireless charging module judges whether a coil which is wirelessly charged is connected with the power supply output port according to the high potential so as to enter a wireless charging mode, the wired charging module judges to stop the wired charging mode according to the high potential, and the output of a wired charging function is stopped;
when the potential of the line connected with the power supply output port is lower than that of the reference line, the wireless charging module judges whether the power supply output port is connected with a wired charging device according to the high potential so as to enter a wired charging mode, the wireless charging module judges to stop the wireless charging mode according to the high potential, and the wireless charging function output is stopped.
9. The charging method according to claim 6, wherein the S300 specifically includes:
s301: detecting a charging specification;
the wired environment detection circuit or the wireless environment detection circuit detects the charging specification of the device to be charged and feeds back the detection data to the first micro-processing unit or the second micro-processing unit;
s302: outputting a specification voltage;
and the first micro-processing unit or the second micro-processing unit outputs different charging voltages according to the charging specification.
10. The charging method of claim 6, prior to the S400, the method further comprising:
s501: detecting a charging environment;
the wired environment detection circuit or the wireless environment detection circuit monitors the current voltage and the temperature of the wired charging module or the wireless charging module in real time;
s502: stopping charging;
when the current voltage and the temperature detected by the wired environment detection circuit or the wireless environment detection circuit in real time exceed preset thresholds, the first micro-processing unit or the second micro-processing unit controls to stop charging.
