Embodiment 1

[0024] figure 2 This is a schematic flow chart of a method for charging a terminal with data exchange function provided in the first embodiment of the present invention. The technical solution of this embodiment is applicable to a terminal with an OTG function. According to the power-on or power-off state of the terminal, it is controlled to execute the data exchange access mode or execute the device charging access mode. The terminal can be any electronic device with OTG function, such as a mobile phone and a tablet computer. The method may be executed by a charging device of a terminal with OTG function, and the device may be implemented in software and / or hardware, and configured to be executed in the terminal. The charging method of the terminal with data exchange function provided in this embodiment specifically includes:

[0025] S110: Detect whether the terminal is in a shutdown state.

[0026] As described above, the USB interface of the terminal has a ground pin GND, an...

Embodiment 2

[0034] image 3 This is a schematic flowchart of a terminal charging method with data exchange function provided in the second embodiment of the present invention. The method may be executed by a charging device of a terminal with OTG function, and the device may be implemented in software and / or hardware, and configured to be executed in the terminal. The charging method of the terminal with data exchange function provided in this embodiment specifically includes:

[0035] S210. Detect whether the terminal sends electromagnetic waves

[0036] When the terminal is in the power-on operating state, the terminal will send electromagnetic signals to communicate or search for nearby networks. Therefore, it can be determined whether the terminal is in the power-on operating state by detecting whether the terminal is sending electromagnetic waves.

[0037] When it is detected that the terminal sends electromagnetic waves, it is determined that the terminal is in the power-on state, and the...

Embodiment 3

[0058] Figure 4 This is a schematic structural diagram of a terminal charging device with data exchange function provided in the third embodiment of the present invention. The device may use software and / or hardware to execute the charging method of the terminal with OTG function described in the foregoing embodiment, and the device is configured to be executed in the terminal.

[0059] The third embodiment provides a terminal charging device with a data exchange function, including: a terminal state detection module 310 and an access mode switching module 320.

[0060] The terminal state detection module 310 is used to detect whether the terminal is in the shutdown state; the access mode switching module 320 is used to turn off the data exchange of the universal serial bus USB interface of the terminal when it is detected that the terminal is in the shutdown state. Access mode and switch to perform device charging access mode.

[0061] Optionally, the terminal state detection mod...

Abstract

The embodiment of the invention discloses a charging method and apparatus of a terminal having a data exchange function. The method comprises: whether a terminal is in a turning-off state is detected; if so, a data exchange access mode of the USB interface of the terminal is turned off and switching to an equipment charging access execution mode is carried out. According to the invention, whether the display panel of the terminal is in a turning-off state is detected and is used as the determination condition of switching to the terminal access mode. Therefore, switching of the access mode of the USB interface of the terminal is realized and a problem that the terminal can not be charged due to short circuit of the identification pin of the USB interface of the terminal in the prior art can be solved.

Description

Technical field [0001] The present invention relates to charging technology, in particular to a charging method and device for a terminal with data exchange function. Background technique [0002] At present, more and more electronic terminal devices such as mobile phones have the function of data exchange (On-The-Go, OTG). After the terminal with OTG function is connected to the OTG device, communication between the devices can be carried out. After the external power supply is connected, the terminal can be charged through the external power supply. [0003] Take the mobile terminal as an example, such as figure 1 Shown is a schematic diagram of a universal serial bus (Universal Serial Bus, USB) interface of a mobile phone provided by the prior art. The USB interface has a ground pin GND, an identification pin ID, a positive voltage data pin D+, and a negative voltage data pin D -And the power supply pin VBUS. The mobile phone detects the OTG device through the identification p...
