Embodiment
For making the object, technical solutions and advantages of the present invention clearly, hereinafter with reference to the accompanying drawing in the embodiment of the present invention, by embodiment, technical scheme of the present invention is described clearly and completely, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
From above-mentioned prior art, when the USB interface that OTG patchcord accesses terminal, terminal is in exchanges data access module, and the power pins of the USB interface of terminal can export 5V voltage, for detecting OTG equipment.When external power supply accesses terminal by OTG patchcord, now terminal cannot be charged by OTG patchcord.
Embodiment one
The schematic diagram of pin in a kind of terminal USB interface that Fig. 2 provides for the embodiment of the present invention one.As shown in Figure 2, a kind of terminal that the embodiment of the present invention one provides, comprise: general-purpose serial bus USB interface, described USB interface comprises power pins VBUS, data pin, identified pins ID and grounding pin GND, wherein, described data pin comprises: positive voltage data pin D+, negative voltage data pin D-.Optionally, described terminal can such as, for having arbitrarily the electronic equipment of OTG function, mobile phone, panel computer etc.
Wherein, the length of the identified pins ID of described USB interface is less than the length of the power pins VBUS of described USB interface.Arrange when the USB interface when terminal can be made to have OTG patchcord to insert like this, the power pins VBUS of terminal USB interface first touches the corresponding pin of OTG patchcord than identified pins ID.
It should be noted that, also the optional length by the power pins of the USB interface of terminal is set to the length being greater than other pins, when OTG patchcord is connected with terminal USB interface, the power pins of terminal USB interface first touches the corresponding pin of OTG patchcord than other pins.Can be direct control terminal actuating equipment charging access module when setting high level monitoring terminal supplying power pin thus.
At this, the concrete length of each pin in terminal USB interface is not construed as limiting, as long as can ensure that the power pins of terminal USB interface first touches the corresponding pin of OTG patchcord than other pins, the now direct control terminal actuating equipment charging access module when monitoring terminal supplying power pin and being setting high level.
The length of the identified pins of optional terminal USB interface is less than or equal to 2/3rds of the length of the power pins of described USB interface, in order to avoid due to OTG patchcord insert terminal USB interface time, because the reason such as direction inclination inserted causes the identified pins ID of described terminal USB interface first to contact OTG patchcord, make terminal may switch to exchanges data access module.
A kind of terminal that the embodiment of the present invention one provides, by changing the length of identified pins in terminal USB interface, makes the power pins of terminal USB interface first touch the corresponding pin of OTG patchcord than other pins.Insert in the process of terminal USB interface in OTG patchcord, terminal can be made first to monitor the state of USB interface power pins, to perform corresponding control according to the state of power pins, after can avoiding inserting OTG patchcord, terminal is in the situation of exchanges data access module.The present embodiment can expand the function of OTG patchcord, makes it can use as charging wire.
It should be noted that, also the optional length by the identified pins ID of OTG patchcord is set to the length being less than other pins, or, the length of the power pins of OTG patchcord is set to the length being greater than other pins, when OTG patchcord is connected with terminal USB interface, the power pins line of terminal USB interface first touches the corresponding pin of OTG patchcord than its identified pins.Can be direct control terminal actuating equipment charging access module when setting high level monitoring terminal supplying power pin thus.

S110, monitor the power pins of the USB interface of described terminal and the level value of identified pins.
This step can be specifically when OTG patchcord is inserted in the USB interface process of terminal, length due to the identified pins ID of described USB interface is less than the length of the power pins VBUS of described USB interface, so terminal supplying power pin VBUS first touches the corresponding pin of OTG patchcord than its identified pins ID.So can first monitor the level value of the power pins of the USB interface of terminal, judge can whether the USB interface of described terminal be connected to power-supply device, namely charge for described terminal.
S120, during insertion, when monitoring described power pins for setting high level, controls described terminal switch to equipment charge access module.
When there being power-supply device to be inserted by OTG patchcord, the power pins of terminal is high level.Therefore in this step when monitor power pins for setting high level time, then can control terminal switch to equipment charge access module, with by power-supply device for terminal is charged.Exemplary, described setting high level can be 5V.
S130, in described insertion process, if monitor described power pins be less than setting high level time, then obtain the level of described identified pins, perform corresponding control according to the level of described identified pins.
For step 110, if monitor power pins be less than setting high level time, terminal does not need to switch to equipment charge access module.Now along with the insert action of OTG patchcord, the identified pins of terminal USB interface contacts with the corresponding pin of OTG patchcord, and terminal can be monitored and be got the level state of identified pins, and performs corresponding control according to the level state of identified pins.
A kind of charging method with the terminal of data exchanging function that the embodiment of the present invention two provides, inserts in OTG patchcord in the process of the USB interface of described terminal, first can monitor the power pins level value of the USB interface of described terminal.When monitoring described power pins for setting high level, control described terminal switch to equipment charge access module; When monitoring described power pins and being less than setting high level, then obtain the level of described identified pins, perform corresponding control according to the level of described identified pins.The present embodiment not only achieves and switches the access module of the USB interface of terminal, and makes OTG patchcord can be used as charging wire to use, and solving terminal in prior art cannot carry out the problem of charging by OTG patchcord.
