Mouth and USB data line, charging current is provided for electronic equipment.
Referring to Fig. 4, when charging equipment and electronic equipment are attached by USB data line, connection that can be just like Fig. 4
In USB interface of the pressure-wire VBUS pins by USB data line and electronic equipment in relation, the USB interface of charging equipment
Pressure-wire VBUS pins are connected, and ground wire GND pin passes through USB data line and the USB of electronic equipment in the USB interface of charging equipment
Ground wire GND pin connection in interface.
In step 302, in charging process is carried out to the electronic equipment using charging equipment, electronic equipment detects the electricity
It whether there is electric current between the pressure-wire and ground wire of sub- equipment, if it is, step 303 is performed, if it is not, then continuing executing with step
Rapid 302 detection process.
It was recognized by the inventor that in the case where electronic equipment does not have any exception, the electric current in charging process is from charging
Pressure-wire VBUS pins in the USB interface of equipment flow to the pressure-wire in the USB interface of electronic equipment by USB data line
VBUS pins, and the USB for flowing to charging equipment by USB data line by the ground wire GND pin in the USB interface of electronic equipment connects
Ground wire GND pin in mouthful, forms current loop.And once charge port short circuit occurs for electronic equipment, then it is likely to result in such as Fig. 5
Situation, that is to say, there is also electric current between the pressure-wire VBUS pins and ground wire GND pin of electronic equipment side, therefore, it can
It whether there is electric current between the pressure-wire of the electronic equipment and ground wire by detecting, to determine whether there occurs charge port short circuit.
And be then probably a part of electricity of charging equipment if there is electric current between the pressure-wire and ground wire of the electronic equipment
Stream has flowed to ground wire without inflow electronic equipment by pressure-wire, then at this point it is possible to be an actually-received according to electronic equipment
Charging current current value and the charging equipment current value of charging current that should export between difference detect that electronics is set
It whether there is electric current between standby pressure-wire and ground wire, for example, electronic equipment can detect reality by built-in galvanometer
The current value of the charging current received, and judge between the current value of the charging current and the pre-set current value of charging equipment
Whether difference is more than predetermined threshold value, if it is greater, then determine to detect there is electric current between the pressure-wire of electronic equipment and ground wire,
And if it is not greater, then determining that electric current is not present.
It should be noted that in view of that may occur when being transmitted by data wire and by other electronic building bricks
Certain current loss, therefore, it can one predetermined threshold value of setting to be weighed, once rather than charging equipment predetermined current
Value is more than the current value for the charging current that electronic equipment is an actually-received, it is assumed that there is electric current between pressure-wire and ground wire.
Certainly, the detection between the pressure-wire and ground wire with the presence or absence of electric current can also have other detection modes, and the embodiment of the present disclosure is not
It is specifically limited.
It should be noted that the detection can be real-time detection or the detection carried out every predetermined period, this public affairs
Embodiment is opened to be not construed as limiting this.
In step 303, if there is electric current between the pressure-wire and ground wire of the electronic equipment, electronic equipment determines charging
Short circuit occurs for mouth, is sent to the charging equipment and stops charging instruction, and the stopping charging instruction is for indicating that the charging equipment stops
Charging to the electronic equipment.
, then can be by USB PD agreements, by agreement when the charging equipment and the electronic equipment support USB PD agreements
Into 24MHZ FSK, ((Frequency-Shift Keying, frequency shift keying) signal is simultaneously coupled to VBUS and drawn the message modulation of layer
It is transmitted on pin by USB data line, to realize the communication between electronic equipment and charging equipment, charging equipment can connect
Receipts are transmitted to the fsk signal of VBUS pins by USB data line, and by being demodulated to fsk signal, to obtain the agreement
The message of layer, to realize the communication between charging equipment and electronic equipment.
It is described to include to charging equipment transmission stopping charging instruction in a kind of possible implementation：The electronics
Equipment sends the stopping charging by the connection between the electronic equipment and the charging equipment, to the charging equipment and referred to
Order.
In fact, the above-mentioned VBUS pins that can essentially refer to electronic equipment of being transmitted by USB data line
In DC level, detected by charging equipment.
In step 304, charging equipment stops the charging to the electronic equipment when receiving the stopping charging instruction.
When charging equipment receives the stopping charging instruction, the output of charging current can be stopped, so as to stop to electricity
The charging of sub- equipment.
The embodiment of the present disclosure is by the current detecting between the VBUS pins and GND pin to electronic equipment, to detect electricity
Whether the charge port of sub- equipment occurs short circuit, so as to when occurring short circuit, stop charging equipment in time to electronic equipment
