Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
For prior art propose problem, the present invention propose a kind of charger and its fill soon protocol analysis method,
System.The method and system can be according to charging equipments from the size of USB_VBus pin obtaining currents and the cycle of obtaining current
To recognize whether charging equipment supports that MTK PE fill soon agreement, and during according to the voltage of USB_DM pins and USB_DP pins
Sequence supports that QC2.0 fills soon agreement or QC3.0 fills soon agreement recognizing charging equipment.Come specifically below with reference to embodiment
The implementation of the bright present invention：
Embodiment one
What the embodiment of the present invention one proposed a kind of charger fills soon protocol analysis method, as shown in figure 1, including following step
Suddenly：
S00：After the USB charging inlets of charging equipment connection charger, obtained by the interface driving circuit of charger
Whether charging equipment recognizes charging equipment from the size of USB_VBus pin obtaining currents and the cycle of obtaining current
Support that MTK PE fill soon agreement.
In embodiment one, charging equipment refers to that smart mobile phone, panel computer etc. need external power source to be charged just
Take formula electronic equipment；Charger refers to and fill agreement soon according to certain, civil power is changed the electricity that backward charging equipment charges
Sub- equipment, such as charger, portable power source.
In embodiment one, the pin of the USB charging inlets being related to is defined as：USB_VBus pins, i.e.,：VCC pin, be
Plant-grid connection pin, charging equipment after being connected with charger, the USB_VBus pins of the USB charging inlets of charger
Just start to provide+5V voltages to charging equipment, fill soon after agreement until detecting, switch other higher electricity such as+9V or+12V
Pressure carries out quick charge；USB_DM pins, i.e.,：D- pins, are data minus pin；USB_DP pins, i.e.,：D+ pins, are data
Positive pin.
For core processor is using the charging equipment of MTK processors, it supports that MTK PE fill soon agreement, treats when this kind of
After charger is connected with charger, can be from the USB_VBus pin obtaining currents of the USB charging inlets of charger, in connection
Early stage, according to MTK PE agreement is filled soon, and the size of obtaining current and the cycle of obtaining current should meet the regulation of agreement, therefore, in reality
In applying example one, by detecting whether charging equipment accords with from the size of USB_VBus pin obtaining currents and the cycle of obtaining current
Close the regulation that MTK PE fill soon agreement, you can identify whether charging equipment supports that MTK PE fill soon agreement：If meeting MTK
PE fills soon the regulation of agreement, then identify that charging equipment supports that MTK PE fill soon agreement；If not meeting MTK PE fills soon agreement
Regulation, then identify that charging equipment does not support that MTK PE fill soon agreement.
S01：After the USB charging inlets of charging equipment connection charger, whether identification charging equipment is that Fructus Mali pumilae sets
It is standby.

Therefore, interface driving circuit may proceed to drive USB_DM pins and USB_DP pins to export 2.7V voltages, Fructus Mali pumilae equipment meeting respectively
Inside voluntarily configures, and+5V the charging voltages exported using the USB_VBus pins of charger complete follow-up charging process.
S02：If identification charging equipment is not Fructus Mali pumilae equipment, by the electricity for detecting USB_DM pins and USB_DP pins
Press sequential to recognize that charging equipment supports that QC2.0 fills soon agreement or QC3.0 fills soon agreement.
Further, as shown in figure 3, step S02 may include following steps：
S021：If identification charging equipment is not Fructus Mali pumilae equipment, control interface drive circuit stop driving USB_DM pins and
USB_DP pin output voltages.
S022：The voltage sequential of USB_DM pins and USB_DP pins is obtained by the interface driving circuit of charger.
S023：If the voltage sequential for obtaining meets the regulation that QC2.0 fills soon agreement, identification charging equipment is supported
QC2.0 fills soon agreement, if the voltage sequential for obtaining meets the regulation that QC3.0 fills soon agreement, identification charging equipment is supported
QC3.0 fills soon agreement.
S03：According to recognition result, parsed and responded based on instruction of the agreement to charging equipment is filled soon accordingly,
Complete the charging to charging equipment.
I other words, according to recognition result, if charging equipment supports that MTK PE fill soon agreement, association is filled soon based on MTK PE
Discuss the instruction to charging equipment to be parsed and responded, complete the charging to charging equipment；If charging equipment is supported
QC2.0 fills soon agreement, then fill instruction of the agreement to charging equipment soon based on QC2.0 and parsed and responded, and completes to treat and fills
The charging of electric equipment；If charging equipment supports that QC3.0 fills soon agreement, agreement is filled soon to charging equipment based on QC3.0
Instruction is parsed and responded, and completes the charging to charging equipment.
The protocol analysis method that fills soon of the charger that the embodiment of the present invention one is provided can be according to charging equipment from USB_
The size of VBus pin obtaining currents and the cycle of obtaining current recognize whether charging equipment supports that MTK PE fill soon agreement,
And according to the voltage sequential of USB_DM pins and USB_DP pins come recognize charging equipment support QC2.0 fill soon agreement or
QC3.0 fills soon agreement, you can identify that main in the market three kind fill soon agreement：MTK PE fill soon agreement, QC2.0 and fill soon
Agreement, QC3.0 fill soon agreement, and agreement can be carried out according to recognition result instructing parsing and response, meanwhile, also support that Fructus Mali pumilae sets
Standby identification, various cell phone apparatus of identification so as to intelligence and fills soon agreement, accurately charge efficiency of the raising to mobile phone.
