Accompanying drawing explanation
The method preferred embodiment flow chart of a kind of charger identification mobile terminal that Fig. 1 provides for invention.
The system function module figure of a kind of charger identification mobile terminal that Fig. 2 provides for the present invention.
Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention further describes.Should be appreciated that specific embodiment described herein, and need not only in order to explain the present invention
In limiting the present invention.
Refer to the method preferred embodiment flow process that Fig. 1, Fig. 1 are a kind of charger identification mobile terminals that the present invention provides
Figure, including step:
S100, arrange when having detected that standard configuration charger connects the most in the terminal, described mobile terminal output one finger
Determine frequency signal to charger USB interface；
When being embodied as, arranging the most in the terminal when having detected that standard configuration charger connects, described mobile terminal is defeated
Go out an assigned frequency signal to charger USB interface, in charger, prestore the output signal of standard configuration mobile terminal simultaneously
Frequency, when judging have connection mobile terminal to charge as described charger, this is electrically charged whether mobile terminal is standard configuration mobile terminal
Basis.In the present embodiment, mobile terminal USB interface is connected with the USB interface of charger, and USB interface all includes that VBUS draws
Foot, DP pin, DM pin and GND pin, wherein, VBUS pin, i.e. Voltage Bus is bus-powered, is to power to USB device
Power line, i.e. USB voltage；DP pin i.e. Data Positive, the positive signal of usb data；DM pin, i.e. Data Minus,
Usb data negative signal, GND pin i.e. Ground i.e. ground wire negative pole, above-mentioned for common knowledge of the prior art, repeat no more.
When described charger USB interface is connected with the USB interface of mobile terminal, when the connection detection module of mobile terminal
Detect mobile terminal USB interface VBUS pin on produce rising edge interrupt time, it is judged that have charger to connect, mobile terminal
The signal control module of side exports an assigned frequency signal to the charger USB interface connected；It is similar to, when the company of mobile terminal
Connect detection module detect mobile terminal USB interface VBUS pin on produce trailing edge interrupt time, it is judged that charger connect
Removing, now the signal control module of mobile terminal side stops exporting described assigned frequency signal to charger USB interface.
Compared to prior art, when the USB interface of mobile terminal detects the USB interface connecting upper charger, charging
Device is not to charge to mobile terminal immediately, but first allows mobile terminal export an assigned frequency signal, improves in prior art and fills
Electrically activate by the problem of mobile terminal side single side control.
S200, when charger detected connection mobile terminal charging time, described charger obtain be electrically charged mobile terminal
The frequency signal of output；

Charger obtains and inputs on the DP pin or DM pin that the method for frequency input signal is detection charger USB interface
Time difference between continuous two rising edges or the trailing edge of signal is T1, utilizes formula to calculate 1/T1 and is input signal frequency
Rate.
After charger obtains the frequency of mobile terminal input signal, charger side frequency judge module judges that charger obtains
The output signal frequency of the standard configuration mobile terminal prestored in the signal frequency of this input taken and charger is the most identical, if
Identical, then it is assumed that this mobile terminal is standard configuration mobile terminal, charger side frequency judge module transmits a signal to described charger
Charge control module, described charger charge control module controls the VBUS pin output voltage of charger USB interface to mobile
Terminal USB interface, starts and charges to mobile terminal, and preferred output voltage is 5V；If differing, it is believed that this mobile terminal is non-
Standard configuration mobile terminal, charger charge control module forbidden energy charger charges.
Meanwhile, if charger is currently for enabling charged state and receiving again the instruction of enable charging, then charger does not enters
Any operation of row, it is to avoid repetitive operation.
In this step, the signal frequency by comparing the mobile terminal output that charger side obtains is deposited in charger in advance
The output signal frequency of the standard configuration mobile terminal of storage, differentiates whether connected mobile terminal is standard configuration mobile terminal, so that
Charger side controls charge initiation, grasps charging initiative, changes charge initiation in prior art and is controlled by mobile terminal side one side
The thinking of system.
Corresponding to the method for described a kind of charger identification mobile terminal, the present invention also provides for a kind of charger identification and moves
The system of terminal, refers to the system function module figure of a kind of charger identification mobile terminal that Fig. 2, Fig. 2 provide for the present invention,
