Fig. 2 is please referred to, Fig. 2 is the flow diagram of equipment detection method provided by the embodiments of the present application.The application is implemented The flow for the equipment detection method that example provides can be as follows：

In a step 101, first voltage is provided for the ID pins of Universal Serial Bus Interface.

In the embodiment of the present application, the Universal Serial Bus Interface of electronic equipment is that mini universal serial bus connects in form Mouth or micro universal serial bus interface support OTG functions.Using OTG functions, electronic equipment can be " host " and " outer If " two kinds of identity work.

It should be noted that in the embodiment of the present application, external equipment accesses electronic equipment with the identity of " peripheral hardware ", accordingly , electronic equipment is worked with " host " identity, and by accessing external equipment, it is logical that electronic equipment can carry out data with external equipment Letter, or expand the function of itself using external equipment.Wherein, external equipment can be USB flash disk, mouse, keyboard, game paddle And other electronic equipments etc..

For example, by taking electronic equipment is mobile phone as an example, mouse can be accessed to the Universal Serial Bus Interface of mobile phone by user, Electronic equipment is operated by mouse；USB flash disk can also be accessed to the Universal Serial Bus Interface of mobile phone by user, pass through hand Machine reads the audio-video document in USB flash disk, carries out the broadcasting of audio-video document, alternatively, storing the file in mobile phone to USB flash disk In, realize file backup etc..

To realize that OTG functions, the Universal Serial Bus Interface of electronic equipment are provided with 5 pins, pin is defined as follows Shown in table 1：

VBUS

D-

D+

ID

GND

Table 1

Wherein, VBUS is power pins, and for providing power supply to the external equipment of access, D-, D+ are signal pins, are used for Carry out data transmission with the external equipment of access, GND is grounding pin, and ID pins different cable endpoint for identification is realized The access detection of external equipment, role zone grade.

In the embodiment of the present application, to realize that the access to external equipment detects, electronic equipment is universal serial bus first The ID pins of interface provide first voltage.

In a step 102, whether the voltage change of detection ID pins reaches preset value.

It should be noted that the external equipment as " peripheral hardware ", the ID pins ground connection of Universal Serial Bus Interface, than Such as, the ID pins of external equipment are grounded by a pull down resistor, wherein pull down resistor can be an individual resistance, also may be used To be that multiple resistance are connected and/or composed in parallel.

In this way, when external equipment accesses electronic equipment, the voltage on electronic equipment ID pins will be by the ID of external equipment Pin drags down.As a result, in the embodiment of the present application, electronic equipment can be after providing first voltage, according to detection for ID pins The voltage change of ID pins, to judge whether its Universal Serial Bus Interface has accessed external equipment.

In the embodiment of the present application, after providing first voltage for the ID pins of Universal Serial Bus Interface, electronic equipment Whether the voltage change of detection ID pins reaches preset value, wherein is detecting that the voltage change of ID pins reaches default When value, determination may have external equipment to access its Universal Serial Bus Interface, not reached in the voltage change for detecting ID pins When to preset value, determine that no external equipment accesses its Universal Serial Bus Interface.

As an implementation, electronic equipment the ID pins for its Universal Serial Bus Interface provide first voltage it Afterwards, voltage detecting is carried out to ID pins in real time, obtains real-time voltage, and calculate the voltage difference of first voltage and the real-time voltage Value, using the voltage difference being calculated as the voltage change of its ID pin.

It should be noted that the ID pins due to external equipment are grounded, when external equipment accesses the general string of electronic equipment When row bus interface, the ID pins for making electronic equipment are equally grounded, are 0V by the voltage pull-down of ID pins.Therefore, this Shen It please will be set as the first electricity for judging whether Universal Serial Bus Interface may access the preset value of external equipment in embodiment The voltage value of pressure, for example, when the first voltage that electronic equipment is provided in the ID for its Universal Serial Bus Interface is 0.5V, it is aforementioned Preset value is also configured to 0.5V.
