From prior art, when having the USB interface short circuit of terminal of OTG function, no matter the USB interface of terminal is inserted with or without external OTG equipment, terminal is in detection to OTG equipment and exchanges data (OTG) access module all the time under off-mode and open state, and now terminal cannot realize charging.
In practical operation, the terminal with OTG function is all generally the OTG communication carried out under open state, does not carry out OTG communication when terminal is in off-mode.So the present invention is by closing the method for its OTG access module when terminal closedown, ensures to realize charging when ID pin lost efficacy, reducing the inconvenience of user.
Embodiment one
A kind of schematic flow sheet with the terminal charging method of data exchanging function that Fig. 2 provides for the embodiment of the present invention one.The technical scheme of this embodiment is applicable to the terminal with OTG function, according to the start of terminal or the state of shutdown, controls the situation performing data switched access pattern or actuating equipment charging access module.Terminal can be the electronic equipment arbitrarily with OTG function, typical in mobile phone, panel computer etc.The method can be performed by the charging device of the terminal with OTG function, and this device can adopt the mode of software and/or hardware to realize, and configuration performs in the terminal.The charging method of the terminal of data exchanging function that what the present embodiment provided have specifically comprises:
S110, detect described terminal and whether be in off-mode.
As mentioned above, the USB interface of terminal has grounding pin GND, identified pins ID, positive voltage data pin D+, negative voltage data pin D-and power pins VBUS.Terminal needs to judge whether to be in off-mode, to judge to enter corresponding exchanges data access module or equipment charge access module, and completes corresponding operation.
Whether this step is in off-mode by sense terminals, as the basis for estimation of forcing terminal to enter charged state, makes terminal be in equipment charge access module in the power-offstate.
S120, when detecting that described terminal is in off-mode, close the USB interface of described terminal exchanges data access module and switch to actuating equipment charge access module.
As mentioned above, when detecting that terminal is in off-mode, even if show that the USB interface access OTG equipment of terminal also cannot perform OTG operation, the exchanges data access module of USB interface of now forcing to control to close a terminal, and the USB interface of control terminal switches to actuating equipment to charge access module.If USB interface has access to power-supply device like this, then terminal can be charged.
It should be noted that, terminal is provided with exchanges data identification circuit, this exchanges data identification circuit is for performing detection to external OTG equipment, identification and access, and namely exchanges data identification circuit performs data switched access pattern.Therefore when detecting that terminal is in off-mode, namely the exchanges data access module controlling the USB interface of closing a terminal is control to close exchanges data identification circuit, makes exchanges data identification circuit stop detecting the access of OTG equipment, identify and accessing.
In this step, no matter USB interface short circuit or normal, as long as detect that terminal is in off-mode, namely force terminal switch to be equipment charge access module, to make when USB interface has power-supply device to access, terminal can be charged.
Whether sense terminals is in the Rule of judgment of off-mode as switching terminal access module by the present embodiment, not only achieve and the access module of the USB interface of terminal is switched, even if the problem that the terminal that the identified pins short circuit also solving the USB interface of terminal in prior art causes also cannot be charged in the power-offstate.
Embodiment two
A kind of schematic flow sheet with the terminal charging method of data exchanging function that Fig. 3 provides for the embodiment of the present invention two.The method can be performed by the charging device of the terminal with OTG function, and this device can adopt the mode of software and/or hardware to realize, and configuration performs in the terminal.The charging method of the terminal of data exchanging function that what the present embodiment provided have specifically comprises:
Whether S210, sense terminals send electromagnetic wave
When terminal is in start running status, terminal can send electromagnetic signal and carry out communicating or search for neighbouring network, therefore whether can send electromagnetic wave by sense terminals and judge whether terminal is in start running status.
When detecting that terminal sends electromagnetic wave, judge that terminal is in open state, the USB interface of corresponding terminal performs data switched access pattern.When detecting that terminal does not send electromagnetic wave, judge that terminal is in off-mode, corresponding control is closed the exchanges data access module of USB interface and is forced terminal switch to be actuating equipment charging access module, to charge.
In this step, whether terminal is sent whether electromagnetic wave is in off-mode basis for estimation as sense terminals.
S220, when detecting that described terminal is in off-mode, the exchanges data access module of the USB interface of closing a terminal also switches to actuating equipment to charge access module.
When detecting that terminal is in off-mode, if present terminal has been in equipment charge access module, then control terminal has continued actuating equipment charging access module.When detecting that terminal is in off-mode, if present terminal is in exchanges data access module, then the exchanges data access module of the USB interface of closing a terminal, and control terminal switches to actuating equipment charging access module.
Alternatively, the concrete implementation of the exchanges data access module of the USB interface of closing a terminal can be: disconnect and transfer to the enable signal that described data in terminal exchanges identification circuit, to close described exchanges data access module.
Terminal control USB interface is in exchanges data access module particular by inputing to exchanges data identification circuit enable signal, makes exchanges data identification circuit be in data exchange mode.When terminal control USB interface is in equipment charge access module, terminal need control to close exchanges data identification circuit makes exchanges data identification circuit no longer be in exchanges data access module.Therefore terminal is by disconnecting the enable signal transferring to exchanges data identification circuit, and to close exchanges data identification circuit, corresponding control closes exchanges data access module.
S230, under equipment charge access module, whether the voltage detecting the power pins of the USB interface of described terminal is more than or equal to charging voltage threshold value.
When the USB interface of terminal switches to equipment charge access module, USB interface needs to be confirmed whether that power-supply device accesses, immediately to carry out equipment charge when there being power-supply device to access.Particularly, whether the voltage signal detecting USB interface power pins is more than or equal to preset charge voltage threshold value, to determine whether charging.If the voltage signal of the power pins of USB interface is more than or equal to charging voltage threshold value, can determine that the USB interface of terminal has power-supply device to access; If the voltage signal of the power pins of USB interface is less than charging voltage threshold value, the USB interface non-transformer equipment access of terminal can be determined.
Whether this step, under equipment charge access module, is more than or equal to charging voltage threshold value by the voltage signal of the power pins of the USB interface of sense terminals, to determine whether USB interface has access to power-supply device.
S240, when detecting that the voltage of power pins is less than charging voltage threshold value, return and continue sense terminals whether send electromagnetic wave.
When determining terminal USB interface non-transformer equipment access, can return and continue sense terminals whether send electromagnetic wave.Perform corresponding control according to the access module of testing result switching terminal.
This step can make terminal can also carry out when USB interface short circuit power-supply device access detect, with solve USB interface short circuit in prior art cause terminal shutdown or open state under all cannot access arrangement charging access module problem.
S250, when the voltage of power pins of USB interface terminal being detected is more than or equal to charging voltage threshold value, carry out equipment charge by USB interface.
When the voltage of the power pins of the USB interface of terminal is more than or equal to charge power supply threshold value, illustrate that terminal USB interface has power-supply device to access, now under equipment charge access module, power-supply device passes through terminal USB interface to terminal charge.
It should be noted that, when sense terminals sends electromagnetic wave, can judge that terminal is in open state, then terminal is in data exchange mode.Therefore also comprising after step S210: S260, under exchanges data access module, when detecting that the identified pins of terminal USB interface is lower than low level state, performing the exchanges data with external equipment.When the identified pins of terminal USB interface is lower than low level state, illustrate that the USB interface place of terminal has detected OTG equipment access, so now terminal can carry out OTG detection, identification and access, to carry out the exchanges data with OTG equipment to the OTG equipment of access.

Apparent, when terminal is in open state, terminal is all generally power in each functional module to its inside, and the power supply of its inside is all generally connect, and the USB interface of corresponding terminal performs data switched access pattern.When terminal is in off-mode, the functional module of the terminal overwhelming majority is all in closed condition, the power supply of terminal inner and these functional modules are in off-state, therefore the off-mode of terminal can be judged by the disconnection of the power supply of terminal inner, corresponding control is closed the exchanges data access module of USB interface and is forced terminal switch to be actuating equipment charging access module, to charge.
Whether the flow process of this charging method is: first whether sense terminals power supply disconnects, concrete, can be disconnected and judging, if so, then determine that terminal is in off-mode by the power supply of the functional module of necessity during detection maintenance terminal works; When detecting that terminal is in off-mode, the exchanges data access module of USB interface of closing a terminal also switches to actuating equipment to charge access module; Under equipment charge access module, whether the voltage of the power pins of the USB interface of sense terminals is more than or equal to charging voltage threshold value; When detecting that the voltage of power pins is more than or equal to charging voltage threshold value, carry out equipment charge by USB interface.
It should be noted that, if when detecting that the power supply of terminal does not disconnect, then determine that terminal is in open state, terminal performs data switched access pattern.When detecting that the identified pins of terminal USB interface is in low level state, can determine that USB interface has external OTG equipment access, then terminal and external OTG equipment can carry out exchanges data.
