Embodiment 1

[0055] This embodiment will be described from the perspective of a power-off processing device. The power-off processing device can be integrated into a terminal and other devices. The terminal can be a mobile Internet device (such as a smart phone, a tablet computer), a smart wearable device (such as a smart Watches) and other electronic devices.

[0056] see figure 1 , figure 1 It is a schematic flowchart of a power-off processing method provided by Embodiment 1 of the present invention. The processing method of this embodiment includes:

[0057] Step S101, acquiring a first voltage value between a first contact and a second contact in an earphone jack of a terminal.

[0058]The terminal of the embodiment of the present invention is illustrated by taking a mobile phone as an example. When the mobile phone falls into the water, what will inevitably happen is that the interior of the mobile phone enters the water. There may be a short circuit in the connecting wire, which ...

Embodiment 2

[0076] This embodiment will further introduce the power-off processing method of the present invention on the basis of Embodiment 1, please refer to image 3 ,include:

[0077] Step S201, acquiring a first voltage value of a first contact and a second contact in an earphone jack of a terminal.

[0078] For example, taking a mobile phone as an example, the voltage value of the ground contact and the microphone contact in the earphone jack can be obtained through the built-in voltage sensor of the mobile phone.

[0079] Step S202, judging whether the first voltage value is within the preset voltage range, if yes, execute step S203, if not, return to step S201.

[0080] For example, if the mobile phone judges that the above-mentioned first voltage value is within the preset voltage range, then it is determined that the ground contact in the earphone interface of the mobile phone is short-circuited with the microphone contact, and step S203 is further performed; if the above-ment...

Embodiment 3

[0099] In order to better implement the above method, an embodiment of the present invention also provides a power-off processing device, which can be integrated into a terminal, and the terminal can be a mobile Internet device (such as a smart phone, a tablet computer), a smart wearable Devices (such as smart watches) and other electronic devices. Such as Figure 4 As shown, the power-off processing device may include: a first acquisition module 301, a first judgment module 302, and a power-off module 303; wherein:

[0100] The first obtaining module 301 is configured to obtain a first voltage value between the first contact and the second contact in the earphone interface of the terminal;

[0101] The first judging module 302 is configured to judge whether the first voltage value is within a preset voltage range;

[0102] The power-off module 303 is configured to perform power-off processing on the terminal when the first judging module 302 judges yes.

[0103] Preferably...

Abstract

The embodiment of the invention discloses a power-off handling method and device. The power-off handling method comprises the following steps of: acquiring a first voltage value between a first contact and a second contact in a terminal earphone interface, judging whether the first voltage value is in the preset voltage range, and if so, carrying out power-off handling on the terminal. In the scheme, by utilization of the characteristic that the voltage between the contacts in the earphone interface can be changed once water enters the terminal earphone interface, power-off handling is carried out on the terminal by detecting the voltage value between the contacts of the earphone interface, so that the terminal can be powered-off automatically once water enters the terminal and a user does not need to carry out any power-off operation. Compared with the prior art, the power-off handling method and device have the advantages the power-off speed and the power-off efficiency are improved and further the terminal can be protected in time.

Description

technical field [0001] The present invention relates to the technical field of terminals, and in particular to a power-off processing method and device. Background technique [0002] With the rapid development of terminal devices, terminal devices such as mobile phones and tablet computers are widely used. Users can use these terminal devices to carry out various activities such as communication and entertainment. [0003] With the popularization of mobile phones, there are more and more cases of mobile phone damage caused by water ingress. The waterproofing of existing waterproof mobile phones on the market mainly adopts mechanical waterproofing, that is, increasing the sealing degree of the terminal, and using materials with high-quality waterproof performance to make the shell. However, the manufacturing cost is high and the process is complicated, and users generally use non-waterproof mobile phones on the market. [0004] In practical applications, once the mobile pho...
