The electronic equipment provided by the application is provided with two operating systems, and each system is provided with a mainboard and a central processing unit, so that the two operating systems can run simultaneously. The operating systems comprise a Windows system, a Unix system, a Netware system, a Linux system, a Mac system, an Android system, an iOS system and the like, the types of the two operating systems can be the same or different, the electronic equipment can increase the applicability of the electronic equipment by providing the two operating systems, and each operating system can provide different application environments for users. When the operating systems need to be connected with the peripheral, the operating systems are generally connected through peripheral interfaces, and each operating system is provided with an independent mainboard and a central processing unit, so that each operating system is provided with a corresponding interface for connecting the peripheral.
As shown in the electronic device 100 of fig. 1, the first operating system 110 may be connected to the peripheral 191 through the peripheral interface 131, the second operating system 120 may be connected to the peripheral 192 through the peripheral interface 132 and the peripheral 193 through the peripheral interface 133, and 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 may be expanded through the hub 141. However, in this design, although the interface module 130 of the electronic device 100 includes 3 peripheral interfaces, the first operating system 110 can use only the peripheral interface 131, and the second operating system 120 can use only the peripheral interface 132 and the peripheral interface 133. When the user switches to the second operating system 120 to still want to use the peripheral 191 after the first operating system 110 uses 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, and the utilization rate of the interface module 130 is low and the use is inconvenient.
The above problem can be solved by adding one switching device, as shown in fig. 2, only 1 multi-port switch 242 is added compared to fig. 1, the multi-port switch 242 switches according to the control command of the first os 210, when the first os 210 is used, the multi-port switch 242 communicates the channel between the interface module 230 and the first os 210, and when the system is switched to the second os 220, the multi-port switch 242 communicates the channel between the interface module 230 and the second os 220. However, since the peripheral interfaces 231, 232 and 233 in the interface module 230 are all connected to the multi-port switch 242, the multi-port switch 242 changes the channels through which the peripheral interfaces 231, 232 and 233 communicate at the same time each time the multi-port switch 242 switches, and the control command sent by the first operating system 210 for controlling the multi-port switch 242 to switch is also simple, and is only used for controlling the multi-port switch 242 to switch to communicate with the currently used operating system, and the channels cannot be switched according to the actual use requirement. For example, when the user sends data from the first operating system 210 to the peripheral 291 and does not finish sending the data, the multi-port switch 242 switches to the second operating system 220, the path between the peripheral 291 and the first operating system 210 is interrupted, and the data sending is terminated.
FIG. 3a is a schematic 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, and the switching module 340 switches a channel between the interface module 330 and the first operating system 310 or the second operating system 320 according to a control instruction of the first operating system 310;
when the first operating system 310 detects a connection request between the interface module 330 and the second operating system 320 in a state where the first operating system 310 is in communication with the interface module 330, the switching module 340 is controlled to connect the channels between the interface module 330 and the second operating system 320, and to determine whether to control the switching module 340 to disconnect the channels between the interface module 330 and the present operating system.
The number of the peripheral interfaces in the interface module 330 can be set arbitrarily, and for convenience of description, in this embodiment, the interface module 330 includes 3 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 both started to run, and usually a default system for use is set for powering on, or a selection interface is provided during powering on, and a system for use is selected according to a user instruction. When the currently used operating system is the first operating system 310, the first operating system 310 communicates with the interface module 330, a connection request of the interface module 330 and the second operating system 320 is equivalent to a user switching to the second operating system 320, and the first operating system 310 sends a switching instruction according to a condition of a peripheral connected with the interface module 330, so as to control the switching module 340 to communicate channels of the interface module 330 and the second operating system 320, and determine whether to control the switching module 340 to disconnect the channels of the interface module 330 and the operating system. Obviously, the control instruction may be issued 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, and for convenience of description and control, the control instruction for selectively controlling the switching module 340 to perform switching is issued by the first operating system 310 in this embodiment. The switching of the switching module 340 may be directly controlled by the first operating system 310, or, as shown in fig. 3b, the switching module 340 may be controlled by the controller 350 according to a control instruction of the first operating system 310, since a power on/off key (not shown) of the electronic device 300 is controlled by the controller 350, the switching module 340 may be controlled by expanding the original function of the controller 350, and the switching module 340 needs to maintain a connection state according to the control instruction, and the power consumption may be greatly reduced by controlling through the controller 350 without adding components.
When the first operating system 310 detects an instruction of switching the system, it needs to control the switching module 340 to switch so that the interface module 330 is connected to the second operating system 320, but it is also necessary to determine whether the interface module 330 and the first operating system 310 can be disconnected, and in an embodiment of the present application, the manner for the first operating system 310 to determine whether to control the switching module 340 to disconnect the channel between the interface module 330 and the present operating system includes any of the following:
if the first operating system 310 detects that the peripheral connected to the operating system is a decryption peripheral, the switching module 340 is controlled not to disconnect the channel between the interface module 330 and the operating system;
if the first operating system 310 detects that the peripheral connected to the operating system is in the continuous communication state, the switching module 340 is controlled not to disconnect the channel between the interface module 330 and the operating system.
As mentioned above, when the first os 310 and the peripheral 391 are in continuous communication, the communication is terminated and the received data may not be complete, so that the control command sent by the first os 310 will keep the channel in the continuous communication state from being disconnected, and of course, the switching module 340 may be controlled to switch the channel to connect the peripheral 391 and the second os 320 when the continuous communication is terminated. For convenience of description, a currently common electronic device 300 having a windows system (the second operating system 320) and an Android system (the first operating system 310) is taken as an example, and since some functions of the windows system are driven based on the Android system, for example, a function of displaying data on a screen, the Android system needs to be always in a running state, and the windows system can realize a display function. After the Android system of the electronic device 300 is encrypted, the electronic device 300 can be normally used only when the Android system is connected with a decryption peripheral, and when the peripheral 392 connected with the peripheral interface 332 is a decryption peripheral, the first operating system 310 controls the peripheral interface 332 to be communicated with a channel of the operating system, and even if the system is switched, the switching module 340 is controlled not to disconnect the channel between the interface module 330 and the operating system, so that the situation that the whole machine cannot be used due to locking after the Android system is disconnected from the decryption peripheral is avoided.
Obviously, to implement the solution of the present application, the switching module 340 needs to set up different channels for different peripheral interfaces, so that the peripheral interfaces in the interface module 330 can be both communicated with the first operating system 310 and the second operating system 320, and the channel where each peripheral interface is located can be independently switched. The channel design schemes are different in form, and only the channel where each peripheral interface is located can be independently switched, and several schemes will be specifically described below.
FIG. 4 is a schematic diagram of an electronic device 400 shown in accordance with yet another exemplary embodiment of the present application; the switch module 440 includes single-ended switches 441, 442, 443 and a multi-ended switch 444, the single-ended switch 441 is connected to the peripheral interface 431, 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 os 410 and the multi-ended switch 444 are connected to the single-ended switches 441, 442, 443; the first operating system 410 and the second operating system 420 are both connected to the multi-port switch 444;
the single-ended switches 441, 442, 443 communicate with the channels between the peripheral interfaces 431, 432, 433 and the first operating system 410 or the multi-ended switch 444 according to the control command of the first operating system 410, and the multi-ended switch 444 communicates with the channels between the single-ended switches 441, 442, 443 and the first operating system 410 or the second operating system 420 according to the control command of the first operating system 410;
when the first operating system 410 detects that the operating system is communicated with the decryption peripheral through the multi-end switchable channel, the control switching module 440 is communicated with the single-end switchable channel between the decryption peripheral and the operating system;
when the first operating system 410 detects a connection request between the interface module 430 and the second operating system 420 in a state of being communicated with the interface module 430, the switching module 440 is controlled to communicate the channels of the interface module 430 and the second operating system 420, and the switching module 440 is controlled not to disconnect the channels of the decryption peripheral, the peripheral in a continuous communication state and the operating system;
wherein the single-ended switchable channel is a communication channel not established through the multi-ended switch 444; the multi-port switchable channel is a communication channel established through the multi-port switch 444.
As shown in fig. 4, the channel of the peripheral 491 connected to the first operating system 410 through the peripheral interface 431, the single-ended switch 441 and the multi-ended switch 444 is a multi-ended switchable channel, and the channel of the peripheral 491 connected to the first operating system 410 through the peripheral interface 431 and the single-ended switch 441 is a single-ended switchable channel.
As shown in fig. 5, when the electronic device 400 is turned on, if the connection and unlocking of the peripheral device is not required, the first operating system 410(Android system) controls the switching module 440 to connect the channel between the interface module 430 and the currently used operating system, and if the connection and unlocking of the peripheral device is required, the control interface module 430 communicates with the Android system through a multi-port switchable channel, when the peripheral 491 is detected to be inserted into the peripheral interface 431, it is determined whether the peripheral 491 is an unlocked peripheral, and when the peripheral 491 is an unlocked peripheral, the electronic device 400 is unlocked, since the multi-end switchable channel also controls the channels of other peripheral interfaces, in order to not affect the normal use of other peripheral interfaces, the single-end switch 441 is controlled to switch, so that the peripheral 491 is communicated with the Android system through the single-end switchable channel, and when the operating system is switched subsequently, the single-ended switch 441 is controlled to keep the current channel not disconnected.
Since the unlocking peripheral may be inserted into any one of the peripheral interfaces 431, 432, 433, if the peripheral interfaces 431, 432, 433 do not have a mark capable of distinguishing a location, it is further necessary to determine which peripheral interface the unlocking peripheral is inserted into, in an embodiment, the first operating system 410 sequentially sends a switching instruction to the single-ended switches 441, 442, 443 through the controller 450, and after the controller 450 controls the single-ended switch 441 to switch, the unlocking peripheral is communicated with the Android system through the single-ended switchable channel, that is, the unlocking peripheral is connected to the peripheral interface 431, it is not necessary to control the single-ended switches 442, 443 to switch.
