Embodiment 1

[0016] refer to figure 1 , shows a flow chart of steps of a power switching method according to Embodiment 1 of the present invention.

[0017] The power switching method of the embodiment of the present invention includes the following steps:

[0018] Step S102: Receive a power-on operation.

[0019] Wherein, the power-on operation includes an operation for instructing to start an emergency power supply, or an operation for instructing to use a main power supply for power-on.

[0020] The operation of turning on the power supply can be generated by pressing the power-on button, and the operation of turning on the emergency power supply can be generated by a combination of buttons set on the device. The specific buttons included in the button combination can be set by those skilled in the art according to actual needs. The present invention This is not specifically limited in the embodiments.

[0021] Step S104: Determine whether the power-on operation is an operation for i...

Embodiment 2

[0033] refer to figure 2 , shows a flow chart of steps of a power switching method according to Embodiment 2 of the present invention.

[0034] The power switching method of the embodiment of the present invention includes the following steps:

[0035] Step S202: Receive a power-on operation.

[0036] Wherein, the power-on operation includes an operation for instructing to start an emergency power supply, or an operation for instructing to use a main power supply for power-on.

[0037] Step S204: Determine whether the power-on operation is an operation for instructing to start an emergency power supply, if not, perform step S206, and if yes, perform a setting operation.

[0038] Wherein, the setting operation may be set as: when the power-on operation is an operation for instructing to start the emergency power supply, connect the emergency power supply to supply power to the device through the emergency power supply.

[0039] Step S206: When the received power-on operatio...

Embodiment 3

[0068] refer to image 3 , shows a schematic structural diagram of a power switching device according to Embodiment 3 of the present invention.

[0069] The power switching device in the embodiment of the present invention may include: a receiving module 302, configured to receive a power-on operation; a first judging module 304, used to judge whether the power-on operation is an operation for instructing to start an emergency power supply; a first starting module 306, used to start the main power supply to perform a power-on operation if the judgment result of the judging module is no; the second judging module 308 is used to judge whether the remaining power of the main power supply is less than the first predetermined value during the power-on process. Set value; the first switching module 310 is used to automatically switch to the emergency power supply if the judgment result of the second judging module 308 is less than the first preset value, and the emergency power supp...

Abstract

The invention provides a power supply switching method and apparatus. The power supply switching method comprises the steps of receiving a starting-up operation; judging whether the starting-up operation is an operation for indicating to start an emergency power supply or not; if so, starting a main power supply to implement the starting-up operation; judging whether the residual electricity of the main power supply is less than a first preset value or not in the starting-up process; if the residual electricity of the main power supply is less than the first preset value, automatically switching to the emergency power supply, and enabling the emergency power supply to supply power to the equipment; and if the residual electricity of the main power supply is greater than or equal to the first preset value, not performing power supply switching, and enabling the main power supply to supply power to the equipment. By adoption of the power supply switching method provided by the embodiment of the invention, the problem of low power or even no power of the equipment can be solved fundamentally.

Description

technical field [0001] The present invention relates to the technical field of mobile smart devices, in particular to a power switching method and device. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, mobile smart devices have become an indispensable part of people's daily life, used to maintain close contact with the surrounding world at all times, greatly promoting the convenience of people's daily life, Improve the efficiency of study work. [0003] At present, the functions provided by mobile smart devices are becoming more and more abundant, and the power consumption is also increasing. In order to meet the normal needs of daily work, the power supply types of mobile smart devices have also begun to innovate, such as: large-capacity batteries and other products . Although these innovations have alleviated the problem of high daily power consumption of mobile smart devices to a certain ext...
