In step 201, the electronic equipment detect the electronics in charging process and set using charging equipment
Standby data pin；
In step 202, if the data pin variation for detecting the electronic equipment is predetermined level, stop to institute
State the charging of electronic equipment.
The embodiment of the present disclosure is by the VBUS pin to electronic equipment and the current detecting between GND pin, to detect electricity
Whether the charge port of sub- equipment occurs short circuit, so as to when short circuit occurs, stop charging equipment in time to electronic equipment
Charging, substantially increases safety, avoids the loss of property.
Fig. 3 is a kind of flow chart of charge port short-circuit protection method shown according to an exemplary embodiment, such as Fig. 3 institute
Show, this method is for including the following steps in the charging process of electronic equipment and charging equipment.
In step 301, charging equipment and electronic equipment are attached, start charging process.
Charging equipment can be used to electronic equipment and provide the equipment of power supply, such as charger or portable mobile power supply
There is USB interface Deng, this kind of charging equipment, can be attached by USB data line with electronic equipment, to be connect by USB
Mouth and USB data line, provide charging current for electronic equipment.
It referring to fig. 4, can connection just like Fig. 4 when charging equipment and electronic equipment are attached by USB data line
Relationship, the pressure-wire VBUS pin in the USB interface of charging equipment pass through in the USB interface of USB data line and electronic equipment
Pressure-wire VBUS pin connects, and ground wire GND pin passes through the USB of USB data line and electronic equipment in the USB interface of charging equipment
Ground wire GND pin connection in interface.
In step 302, the electronic equipment is being carried out in charging process 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 so, 303 are thened follow the steps, if it is not, then continuing to execute step
Rapid 302 detection process.
It was recognized by the inventor that the electric current in charging process is from charging in the case where electronic equipment does not have any exception
Pressure-wire VBUS pin in the USB interface of equipment flows to the pressure-wire in the USB interface of electronic equipment by USB data line
VBUS pin, and connect by the ground wire GND pin in the USB interface of electronic equipment by the USB that USB data line flows to charging equipment
Ground wire GND pin in mouthful forms current loop.Once and charge port short circuit occurs for electronic equipment, then is likely to result in such as Fig. 5
Situation that is to say that there is also electric currents between the pressure-wire VBUS pin and ground wire GND pin of electronic equipment side, therefore, can be with
By detecting with the presence or absence of electric current between the pressure-wire of the electronic equipment and ground wire, to determine whether to have occurred charge port short circuit.
And if there are electric currents between the pressure-wire and ground wire of the electronic equipment, it may be a part of electricity of charging equipment
Stream has flowed to ground wire by pressure-wire without flowing into electronic equipment, then at this point it is possible to be an actually-received according to electronic equipment
Charging current current value and the current value of charging current that should export of charging equipment between difference set to detect electronics
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 greater than preset threshold, if it is greater, then confirmly detect between the pressure-wire of electronic equipment and ground wire there are electric current,
And electric current is not present if it is not greater, then determining.
It should be noted that in view of transmit and by that may occur when other electronic building bricks by data line
Therefore certain current loss can set a preset threshold to be measured, once rather than the predetermined current of charging equipment
Value is greater than the current value for the charging current that electronic equipment is an actually-received, it is assumed that there are electric currents 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, it is also possible to the detection carried out every predetermined period, this public affairs
It opens embodiment and this is not construed as limiting.
In step 303, if there are electric current between the pressure-wire and ground wire of the electronic equipment, electronic equipment determines charging
Short circuit occurs for mouth, sets the first level for the anode of the data pin, sets second for the cathode of the data pin
Level.
In the embodiments of the present disclosure, electronic equipment and charger can support that the preset level about data pin is assisted
View so that electronic equipment determine charge port occur short circuit when, can be according to the preset level agreement, to draw to the data of itself
Foot carries out corresponding level setting, to notifying the situation of the short circuit to charger.It that is to say, above-mentioned steps 303 are actually
It is the process for setting the data pin of the electronic equipment to predetermined level, the predetermined level is used to indicate the charging and sets
The standby charging stopped to the electronic equipment.
For example, first level can be 3 to 3.5 volts, and second electrical level can be 0.5 to 0.7 volt, optionally,
First level can be 3.3 volts, and second electrical level can be 0.6 volt.
In step 304, if charging equipment detects that the data pin variation of the electronic equipment is predetermined level,
Stop the charging to the electronic equipment.
Charging equipment carries out in charging process to electronic equipment, can continue the data pin for detecting electronic equipment, work as inspection
When to measure data pin variation be predetermined level, it is determined that it is short-circuit that charge port occurs for the electronic equipment, therefore can stop
Only to the charging of electronic equipment.For example, when charging equipment detects the anode variation of the data pin of electronic equipment for the first electricity
Flat, the cathode variation of the data pin is second electrical level, then stops the charging to electronic equipment.
The embodiment of the present disclosure is by the VBUS pin to electronic equipment and the current detecting between GND pin, to detect electricity
Whether the charge port of sub- equipment occurs short circuit, so as to when short circuit occurs, stop charging equipment in time to electronic equipment
Charging, substantially increases safety, avoids the loss of property.Further, it is set by using by the level of data pin
The situation to notify charging equipment charging circuit short circuit is set, timeliness is stronger, and not will increase actual hardware, need to only locate
Reason device level can be judged according to detected level conditions, reduce actual cost.
