detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with aspects of the present application as detailed in the appended claims.

The terminology used in the present application is for the purpose of describing particular embodiments, and is not intended to be limiting. The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used to describe various information in this application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information without departing from the scope of the present application. Similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to a determination."

The electronic device involved in the present application has two operating systems, each of which is configured with a main board and a central processing unit, so that the two operating systems can operate simultaneously. The operating system includes Windows system, Unix system, Netware system, Linux system, Mac system, Android system, iOS system, etc. The types of the two operating systems may be the same or different. The electronic device of the present application can provide two operating systems. Increasing the applicability of electronic devices, each operating system can provide users with different application environments. When the operating system needs to be connected to a peripheral device, it is usually connected through a peripheral interface. Since each operating system has a separate motherboard and a central processing unit, each operating system has a corresponding interface for connecting peripherals.

As shown in FIG. 1 , the first operating system 110 can be connected to the peripheral device 191 through the peripheral interface 131 , and the second operating system 120 can be connected to the peripheral device 192 through the peripheral interface 132 and through the peripheral interface 133 . The peripheral device 193 is connected. When the number of such interfaces in the second operating system 120 is limited and cannot be directly connected to the peripheral interface 132 and the peripheral interface 133, the number of interfaces can be expanded by the hub 141. However, in this design mode, although the interface module 130 of the electronic device 100 has three peripheral interfaces, the first operating system 110 can only use the peripheral interface 131, and the first operating system 120 can only use the peripheral interface 132. Peripheral interface 133. When the user uses the peripheral device 191 in the first operating system 110, When switching to the second operating system 120 still wants to use the peripheral 191, the peripheral 191 needs to be manually inserted into the peripheral interface 132 or the peripheral interface 133 to use the peripheral 191 in the second operating system 120, the interface module 130 The utilization rate is low and it is not easy to use.

The above problem can be solved by adding a switching device. As shown in FIG. 2, only one multi-terminal switch 242 is added compared with FIG. 1, and the multi-end switch 242 switches according to the control command of the first operating system 210, and is in use. In the first operating system 210, the multi-end switch 242 is connected to the channel between the interface module 230 and the first operating system 210. When the system is switched to the second operating system 220, the multi-terminal switch 242 is connected between the interface module 230 and the second operating system 220. Channel. However, since the peripheral interface 231, the peripheral interface 232, and the peripheral interface 233 in the interface module 230 are all connected to the multi-terminal switch 242, the multi-terminal switch 242 changes the peripheral interface 231 and the peripheral interface 232 at the same time. The channel of the peripheral interface 233 is connected, and the control command sent by the first operating system 210 for controlling the switching of the multi-end switch 242 is also simple, and is only used to control the multi-end switch 242 to switch to communicate with the currently used operating system, and cannot be based on Actually use the demand switching channel. For example, when the user sends data from the first operating system 210 to the peripheral device 291, and switches to the second operating system 220 when the transmission is not completed, the multi-end switch 242 switches, interrupting the peripheral device 291 and the first operating system 210. Path, data transmission is terminated.

3a is a schematic structural diagram of an electronic device according to an exemplary embodiment of the present application; as shown in FIG. 3a, the electronic device 300 includes an interface module 330, a switching module 340, a first operating system 310, and a second operating system 320. The interface module 330 is connected to the first operating system 310 or the second operating system 320 through the switching module 340. The switching module 340 switches the interface module 330 to the first operating system 310 or the second operating system 320 according to the control instruction of the first operating system 310. Channel between

When the first operating system 310 is in communication with the interface module 330, when detecting the connection request of the interface module 330 and the second operating system 320, the control switching module 340 connects the channel of the interface module 330 and the second operating system 320, and determines Whether to control the switching module 340 to disconnect the interface module 330 from the channel of the operating system.

The number of the peripheral interfaces in the interface module 330 can be arbitrarily set. For convenience of description, in the embodiment, the interface module 330 includes three peripheral interfaces (the peripheral interface 331, the peripheral interface 332, and the peripheral interface 333) as an example for description. .

When the electronic device 300 is powered on, the first operating system 310 and the second operating system 320 are all started to run. Usually, the system used by the power-on default is set, or a selection interface is provided at the time of power-on, and the system used is selected according to the user's instruction. When the first operating system 310 is currently used, the first operating system 310 is in communication with the interface module 330, and the connection request of the interface module 330 and the second operating system 320 is equivalent to the user switching to the second operating system 320, the first operation. The system 310 sends a switching instruction according to the situation of the peripheral device connected to the interface module 330 to control the switching module 340 to communicate with the channel of the interface module 330 and the second operating system 320, and determines whether to control the switching module 340 to disconnect the interface module 330 from the operation. systematic aisle. Obviously, the control instruction may be sent by the first operating system 310 or the second operating system 320, or the first operating system 310 and the second operating system 320 jointly control the switching of the switching module 340. For convenience of description and control, the embodiment The control command that selects the control switching module 340 to perform the switching is issued by the first operating system 310. The switching of the switching module 340 may be directly controlled by the first operating system 310. Alternatively, as shown in FIG. 3b, the controller 350 controls the switching module 340 according to the control instruction of the first operating system 310, due to the switch button of the electronic device 300 ( The control unit 350 controls the switching module 340 by expanding the function of the original controller 350, and the switching module 340 needs to maintain the connected state according to the control command, and passes through the controller 350. The way to control can greatly reduce power consumption without adding components.

When detecting the instruction of the switching system, the first operating system 310 needs to control the switching module 340 to perform switching so that the interface module 330 is in communication with the second operating system 320, but whether the interface module 330 and the first operating system 310 can be disconnected. The manner in which the first operating system 310 determines whether to control the switching module 340 to disconnect the interface between the interface module 330 and the operating system includes any of the following:

If the first operating system 310 detects that the peripheral connected to the operating system is a decrypted peripheral, the control switching module 340 does not disconnect the interface between the interface module 330 and the operating system;

When the first operating system 310 detects that the peripheral connected to the operating system is in a continuous communication state, the control switching module 340 does not disconnect the interface between the interface module 330 and the operating system.

As described above, when the first operating system 310 and the peripheral device 391 are continuously communicating, the path is disconnected, the communication is terminated, and the received data may be incomplete. Therefore, the control command sent by the first operating system 310 remains in the continuous communication state. The channel is not disconnected. Of course, the switching module 340 can also be controlled to switch the channel to allow the peripheral device 391 to communicate with the second operating system 320 at the end of the continuous communication. Some programs need to be connected to a decryption peripheral (such as a dongle) to be able to run normally. For the convenience of description, the current common electronic devices with Windows system (second operating system 320) and Android system (first operating system 310) are used here. For example, since some functions of the windows system are driven by the Android system, for example, the function of displaying data on the screen requires that the Android system is always in a running state, and the windows system can realize the display function. After the Android system of the electronic device 300 is encrypted, the electronic device 300 can be used normally only when the Android system is connected to the decryption peripheral. When the peripheral device 392 connected to the peripheral interface 332 is a decrypting peripheral, the first operating system 310 controls. The peripheral interface 332 is kept in communication with the channel of the operating system. Even when the system is switched, the switching module 340 is controlled to not disconnect the interface between the interface module 330 and the operating system, so as to avoid the locking of the Android system and the decrypting peripheral. Lock is not available.

Obviously, to implement the solution of the present application, the switching module 340 needs to set different channels for different peripheral interfaces, so that the peripheral interfaces in the interface module 330 can communicate with the first operating system 310 and the second operating system 320, and Independently The channel in which each peripheral interface is located is switched. The channel design schemes are different in form, as long as the channels in which each peripheral interface is located can be switched independently. Next, several schemes will be specifically introduced.

FIG. 4 is a schematic structural diagram of an electronic device 400 according to still another exemplary embodiment of the present application; the switching module 440 includes a single-ended

switch

441, 442, 443 and a multi-terminal switch 444, and the single-ended switch 441 and the peripheral interface 431 is connected, the single-ended switch 442 is connected to the peripheral interface 432, the single-ended switch 443 is connected to the peripheral interface 433, and the first operating system 410 and the multi-end switch 444 are connected to the single-ended

switch

441, 442, 443; The first operating system 410 and the second operating system 420 are both connected to the multi-end switch 444;

The single-ended

switch

441, 442, 443 communicates the channel between the

peripheral interface

431, 432, 433 and the first operating system 410 or the multi-end switch 444 according to the control instruction of the first operating system 410, and the multi-end switch 444 is according to the first The control instruction of the operating system 410 connects the channel between the single-ended

switch

441, 442, 443 and the first operating system 410 or the second operating system 420;

The first operating system 410 controls the switching module 440 to communicate with the single-ended switchable channel between the decryption peripheral and the operating system when detecting that the operating system and the decryption peripheral are connected through the multi-terminal switchable channel;

When the first operating system 410 is in communication with the interface module 430, when detecting the connection request of the interface module 430 and the second operating system 420, the control switching module 440 connects the channel of the interface module 430 and the second operating system 420, and controls The switching module 440 does not disconnect the peripherals of the peripheral device and the operating system that decrypt the peripheral device, the continuous communication state;

The single-ended switchable channel is a communication channel that is not established by the multi-terminal switch 444; the multi-terminal switchable channel is a communication channel established by the multi-terminal switch 444.

As shown in FIG. 4, the peripheral device 491 is connected to the first operating system 410 through the peripheral interface 431, the single-ended switch 441, and the multi-terminal switch 444, and the peripheral device 491 passes through the peripheral interface 431, The channel connected to the first operating system 410 by the end switch 441 is a single-ended switchable channel.

As shown in FIG. 5, when the electronic device 400 is powered on, if the connection unlocking peripheral is not required to be unlocked, the first operating system 410 (Android system) controls the switching module 440 to communicate the channel between the interface module 430 and the currently used operating system. If the connection is required to unlock the peripheral, the control interface module 430 is connected to the Android system through the multi-terminal switchable channel. When the peripheral device 491 is inserted into the peripheral interface 431, it is determined whether the peripheral 491 is an unlocked peripheral. When the peripheral device 491 is an unlocked peripheral device, the electronic device 400 is unlocked. Since the multi-terminal switchable channel also controls the channels of other peripheral interfaces, the single-ended switch 441 is controlled to switch without affecting the normal use of other peripheral interfaces. The peripheral device 491 is connected to the Android system through the single-ended switchable channel, and when the operating system is subsequently switched, the single-ended switch 441 is controlled to keep the current channel unbroken.

Since the unlocking peripheral may be inserted in any one of the

peripheral interfaces

431, 432, and 433, if the

peripheral interfaces

431, 432, and 433 have no distinguishable position flag, it is also necessary to determine which peripheral device is inserted by the unlocking peripheral. In an embodiment, the first operating system 410 sends a switching instruction to the single-ended

switch

441, 442, 443 through the controller 450. When the controller 450 controls the single-ended switch 441 to switch, the peripheral is unlocked. The single-ended switchable channel is connected to the Android system, that is, the unlocked peripheral is connected to the peripheral interface 431, so that it is no longer necessary to control the single-ended

switch

442, 443 to switch.

The

peripheral interfaces

432, 433 are still in communication with the first operating system 410 through the multi-terminal switchable channel. When switching to the second operating system 420, the control switching module 440 is in communication with the second operating system 420, of course, if the peripherals 492 and / Or the peripheral device 493 is in a continuous communication state with the first operating system 410, then the switching module 440 is first controlled not to switch until the

peripherals

492, 493 and the first operating system 410 end the continuous communication state; or the user is asked whether to force Switching, according to the instruction triggered by the user, controls whether the switching module 440 switches. Through the above manner, the purpose of switching the control channel according to the actual use requirement can be achieved, and the channels of each peripheral interface can be independently controlled.
