Embodiment 1

[0085] refer to figure 2 , the operating method of the terminal device according to the first embodiment of the present invention is proposed, and the operating method includes the following steps:

[0086] S11. Providing a charging mode for the user to select. It is judged whether the user has selected the charging mode, and when the user has selected the charging mode, enter step S12; when the user has not selected the charging mode, the process ends.

[0087] In the prior art, the USB interface of the terminal device is of SDP type. When the terminal device is connected to the slave as the host through the USB interface, it can only supply power to the slave with a small current, mainly for USB data transmission with the slave, so only the data Transmission mode (or called USB OTG mode). In the embodiment of the present invention, a charging mode (or charging treasure mode) is added to the terminal device. In the charging mode, the USB interface of the terminal device ca...

Embodiment 2

[0099] refer to image 3 , propose the operation method of the terminal device according to the second embodiment of the present invention, the operation method includes the following steps:

[0100] S21 , providing a charging mode in an option menu for the user to select. It is judged whether the user has selected the charging mode, and when the user has selected the charging mode, enter step S22; when the user has not selected the charging mode, the process ends.

[0101] Optionally, the terminal device can set the charging mode switch in the option menu, and switch the state of the charging mode switch according to the user's operation. When the charging mode switch is switched to the first state, it is determined that the user has selected the charging mode. When the charging mode switch is switched In the second state, it is determined that the user has not selected the charging mode, and then the default mode (data transmission mode or other modes) is maintained. The u...

Embodiment 3

[0111] refer to Figure 4 , propose the operating method of the terminal device according to the third embodiment of the present invention, the operating method includes the following steps:

[0112] S31. The terminal device is connected to an external device through a USB interface. Judging whether the terminal device is a master, if the terminal device is a master, enter step S32; when the terminal device is a slave, end the process.

[0113] Specifically, when the terminal device establishes an OTG connection with the external device through the USB interface, it is detected whether the terminal device belongs to the host or the slave. Optionally, the terminal device detects whether the UID signal is valid, and when the UID signal is valid, it determines that the device is the master, otherwise it determines that the device is the slave.

[0114] S32. Prompting the user to select a charging mode. It is judged whether the user has selected the charging mode, and when the ...

Abstract

The invention discloses a piece of terminal equipment and an operation method and an operation device for the same. The terminal equipment comprises a USB interface, wherein the USB interface comprises two signal pins. The method comprises the steps that a selective charging mode is provided for a user; and when the user selects the charging mode, short-circuit connection is conducted to the two signal pins of the USB interface, so that the USB interface can be simulated into a DCP type. The operation method for the terminal equipment provided by the embodiment of the invention is characterized in that the selective charging mode is provided for the user, so the short-circuit connection of the two signal pins of the USB interface can be achieved when the user selects the charging mode, and thus the USB interface is simulated into the DCP type; large-current power supply can be achieved when the terminal equipment conducts external power supply, so the charging speed is increased; and the technical problem that the charging speed is slow during external charging of the terminal equipment can be solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a terminal device, an operating method and an operating device thereof. Background technique [0002] Universal Serial Bus (USB) powering portable devices has become a standard application along with its serial communication function. Today, USB power delivery has been extended to battery charging, wall adapters and other forms of power applications. A notable effect brought by the popularization of applications is that the charging and power supply of portable devices can be interchanged with plugs and adapters. As a result, current solutions allow multiple power sources to be used for charging, as opposed to past architectures that used dedicated adapters for each device. [0003] Taking USB2.0 as an example, there are 5 pins (PIN) in the USB2.0mini interface, including: [0004] A pair of power pins: VBUS / GND [0005] A pair of signal pins: D+ / D- [0006] One ...
