Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below through embodiments with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

In the description of the present invention, the meaning of a plurality is one or more, the meaning of a plurality is two or more, and the above, below, exceeding, etc. are understood as excluding the present numbers, and the above, below, within, etc. are understood as including the present numbers. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise specifically limited, the terms such as set forth and the like should be construed broadly, and those skilled in the art can reasonably determine the specific meanings of the above terms in combination with the detailed contents of the technical solutions.

In the description of the present invention, reference to the description of "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples", etc., means that a particular feature or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Referring to fig. 1 and 2, an embodiment of the present application discloses an all-in-one machine, including:

and the peripheral equipment comprises a storage component (a memory, an EMMC, a hard disk and the like), a microphone, a camera, a display screen, a loudspeaker and a communication module (such as Bluetooth, a network module and the like).

A control module configured to include a sleep mode and a standby mode, the control module turning off power to the storage assembly, the microphone, and the camera in the standby mode; in a sleep mode, the control module reserves the power supply of the storage component and closes the power supply of the microphone and the camera. The control module may refer to a module composed of one or more processors for implementing the above-described functions. It may be a combination including a master control chip and a power management chip. For example, the main control chip may be used to complete an interface for detecting connection between the camera and the microphone, and a main body for generating control instructions, and the power management chip is an object for actually controlling execution.

The main difference between the sleep mode and the standby mode is that the storage component is still in a power supply state in the sleep mode, and the processor may be in a low power consumption state and a normal active state in the sleep mode; this means that in the sleep state, the processor of the all-in-one machine can actually still perform operations, so that the background program can continue to operate in the screen-off state. If the camera (built-in or external) or the microphone (built-in or external) is called by the background program, it means that the user may be carelessly obtained private information by the background program, such as audio recording, video recording and the like.

Therefore, in the scheme, when the equipment enters the sleep mode, the power supply of the microphone and the camera is turned off, so that the input equipment cannot acquire field information. Therefore, the background program can be prevented from stealing and recording the field state. Meanwhile, the purpose of the sleep mode can be achieved by maintaining the power supply of the storage device, namely, the device can quickly recover the basic state before sleeping from the sleep state while saving the electric quantity.

It will be appreciated that in order to avoid shutting down important peripherals in a sleep state, such that some functions of the software that do not involve privacy problems cannot be used normally, it is necessary to shut down the power supply to the microphone and camera relatively accurately. Typically, both the microphone (array) and the camera are connected to the motherboard using a USB interface. Of course, it is not excluded that there are devices connected by I2C and common serial ports, and even different interfaces may be controlled by controlling the power supply.

In some embodiments, the control module is further configured to determine, by reading the USB device node list, a USB interface corresponding to the microphone and the camera according to an attribute of a device in the USB device node list, and implement power supply control over the microphone and the camera by controlling power supply to the USB interface. The control module checks the microphones and the cameras in the USB device node list each time it is determined to enter the sleep mode.

An android system and a windows system may be loaded in the all-in-one machine, the systems all include a USB device node list, which USB nodes are connected with the devices currently can be read by reading the USB device node list, and what the devices are can be determined according to the device attributes in the list. Then, the control module can prevent the camera or the microphone from being called by turning off the power supply of the corresponding USB interface. In the embodiment in this section, a manner of querying a node list of the USB device is used, which can determine the current device status on the spot, and perform detection before each sleep, so as to ensure the accuracy of the result.

In other embodiments, an android system is mounted on the control module, a USB corresponding to the microphone and a USB corresponding to the camera, which are identified when the android system is initialized, record a text in a preset position, and when the control module determines to enter the sleep mode, the control module determines, according to contents in the text, that the USB interface requiring power supply shutdown is provided. In the method, the actions of the android system during initialization are utilized, codes can be added into a code block of the initialization equipment, and USB interfaces corresponding to the accessed camera and the accessed microphone are recorded in a local document, so that the equipment list does not need to be read again during sleep, and the speed is higher when the camera and the microphone are closed.

In some embodiments, to address situations where bluetooth is directly connected to the device and not recognized as a camera/microphone, the control module may also be configured to control powering off the bluetooth module when entering the sleep mode.

Referring to fig. 2, an embodiment of the present application provides a power supply control method for an all-in-one machine, including:

s1, determining to enter a sleep mode.

And S2, closing the display screen. It may be the case for the liquid crystal display that its backlight is turned off and turning off the display may be the interruption of its power supply.

And S3, closing the horn. It is to be understood that turning off the horn may be turning off the horn, powering the power amplification board, turning it into a mute state, and the like, and it is to be understood that the order of steps S2 to S4 may be replaced or performed simultaneously. The present embodiment merely provides an example of the sequence.

And S4, judging whether a camera or a microphone exists, and if so, closing the power supply of the existing camera and microphone to enter a sleep mode.

Wherein, whether judge to have camera or microphone specifically is:

and determining whether a microphone or a camera exists by reading the attribute of the equipment in the USB equipment node list. In order to ensure that a camera or a microphone connected after the all-in-one machine is started is detected, the microphone and the camera in the USB device node list are checked when the all-in-one machine is determined to enter the sleep mode.
