Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
Fig. 1 is a schematic structural diagram of a terminal device for switching between multiple operating systems according to an embodiment of the present application. As shown in fig. 1, the apparatus provided in the embodiment of the present application may include: the power supply 110, the first storage device 120 storing the first operating system, the second storage device 130 storing the second operating system, the first switch S1, the second switch S2, the control unit 140, and the main board 150.
In some embodiments of the present application, the terminal device may refer to a tablet computer, a mobile phone, and the like.
The voltage output by the power source 110 may be voltages with different voltage values, for example, the voltage output by the power source 110 may be +12V, may also be +5V, or may have both +12V and + 5V. For example, existing computer storage devices such as solid state drives and mechanical hard drives have two sets of interfaces. One group is a data transmission interface, and the other group is a working power supply interface. Taking a mechanical hard disk as an example, the power interface has two power supply modes, one is single voltage +5V or +12V, and the other is dual-voltage power supply +5V and + 12V.
It should be noted that the first operating system stored in the first storage unit 120 and the second operating system stored in the second storage unit 130 are different from each other. For example, a Windows operating system is stored in the first storage unit 120, and a Linux operating system is stored in the second storage unit 130.
In one embodiment of the present application, the first storage device 130 and the second storage device 140 may be two independent hard disks.
In one embodiment of the present application, the first switch S1 and the second switch S2 are two separate two-pole push button switches, as shown in fig. 1. When the double-pole button switch is pressed, the normally open contact of the double-pole button switch is closed, two independent signals are generated, one signal provides a control signal for the control unit 140, the other signal is a starting trigger signal of the power supply 110, and the power supply is started, namely the power supply 110 is started synchronously. When the double-pole switch button is released, the original working state is recovered under the action of the return spring.
Through the technical scheme, the power supply for the first storage device 120 or the second storage device 130 is realized while the power supply 110 is turned on. For example, as shown in fig. 1, when the first double-pole push button switch S1 is pressed, the normally open contact of the first double-pole push button switch S1 is closed, and two independent trigger signals are generated, one of which provides the trigger signal for the control unit 140, and the other of which is the start trigger signal of the power supply 110 to start the power supply.
As shown in fig. 1, a first input terminal of the control unit 140 is connected to the power supply 110 through a first switch S1, a second input terminal and a third input terminal of the control unit 140 are both connected to the power supply 110, a fourth input terminal of the control unit 140 is connected to the power supply 110 through a second switch S2, a fifth input terminal of the control unit 140 is connected to the power supply 110, a first output terminal of the control unit 140 is connected to the first storage device 120, and a second output terminal of the control unit 140 is connected to the second storage device 130. One end of the main board 150 is connected to the power supply 110, and the other end of the main board 150 is connected to the first storage device 120 and the second storage device 130, respectively.
In this embodiment, one end of the motherboard 150 is connected to the power supply 110, and the other end is connected to the first storage device 120 and the second storage device 130, respectively, so that when the terminal is started, the motherboard 150 can read a corresponding operating system and an application program from the power-supplied storage device.
As shown in FIG. 1, the other end of the second relay first normally closed contact J2-2 is grounded, and one end of the second relay first normally closed contact J2-2, which is grounded, is used as a third output end of the control unit 140. The other end of the first relay first normally closed contact J1-2 is grounded, and one end of the first relay first normally closed contact J1-2, which is grounded, is used as a fourth output end of the control unit 140.
The following description will be given by taking the Windows operating system stored in the first storage device 120 and the Linux operating system stored in the second storage unit 130 as an example:
the Windows operating system is stored in the first storage device 120, the Linux operating system is stored in the second storage unit 130, the first switch S1 corresponds to the first storage device 130, and the second switch corresponds to the second storage device 140.
The process of the user using the Windows operating system, i.e. booting the first storage device 120, is: by depressing the first switch S1, the control unit 140 is turned on and a first output of the control unit 140 has a current output to power the first storage device 120. A second output terminal of the control unit 140 has no current output and cannot supply power to the second storage device 130. The main board 150 obtains the Windows operating system from the first storage device 120, and completes the process of selecting the Windows operating system for the terminal.
The process of the user using the Linux operating system, i.e. starting the first storage device 130, is as follows: pressing the second switch S2 turns the control unit 140 on, causing no current to be output from the first output of the control unit 140 and a current to be output from the second output of the control unit to power the second storage device 130 and not the first storage device 120. The main board 150 of the terminal device obtains the Linux operating system from the second storage device 130, and completes the process of selecting the Linux operating system for the terminal.
In the embodiment of the present application, through the above technical solution, the first storage device 120 and the second storage device 130 can be independently powered, and substantial isolation is formed between the storage devices, so that influence on use of other operating systems due to damage of one operating system is avoided.
In some embodiments of the present application, as shown in fig. 1, the control unit 140 includes: the first relay and the second relay. The first relay comprises a first relay coil J1-S, a first relay first normally open contact J1-1, a first relay first normally closed contact J1-2 and a first relay second normally open contact J1-3. The second relay comprises a second relay coil J2-S, a second relay first normally open contact J2-1, a second relay first normally closed contact J2-2 and a second relay second normally open contact J2-3.
Further, as shown in fig. 1, one end of the first relay first normally open contact J1-1 of the first relay is connected to one end of the second relay first normally closed contact J2-2 through the first relay coil J1-S. The connection point of the first relay first normally open contact J1-1 and the first relay coil J1-S is used as a first input end of the control unit 140. The other end of the first relay first normally open contact J1-1 serves as a second input end of the control unit 140. The first relay second normally open contact J1-3 is connected to one end of the power supply 110 and serves as a third input terminal of the control unit 140. The first relay second normally open contact J1-3 is connected to one end of the first storage device 120 as a first output terminal of the control unit 140.
The second relay first normally open contact J2-1 is connected to one end of the first relay first normally closed contact J1-2 through a second relay coil J2-S. And a connection point of the second relay first normally-open contact J2-1 and the second relay coil J2-S is used as a fourth input end of the control unit 140. And one end of the second relay, which is connected with the power supply 110, of the second normally open contact J2-3 is used as a fifth input end of the control unit 140. The second relay first normally open contact J2-1 is connected to the other end of the power source 110 and serves as a sixth input terminal of the control unit 140. And one end of the second relay, which is connected with the second storage device 130, is used as a second output end of the control unit, and the second normally-open contact J2-3 is used as a second output end of the control unit. The other end of the second relay first normally closed contact J2-2 is grounded, and one end of the second relay first normally closed contact J2-2, which is grounded, is used as a third output of the control unit 140. The other end of the first relay first normally closed contact J1-2 is grounded, and one end of the first relay first normally closed contact (J1-2) which is grounded is used as a fourth output end of the control unit 140.
The following description will be made by taking the example of pressing the first switch S1:
the first switch S1 is closed and the second relay is not energized, so that the second relay first normally closed contact J2-2 of the second relay maintains a closed state. The first relay is electrified, the first relay coil J1-S of the first relay is electrified, so that the first relay normally open contact J1-1 and the first relay normally open contact J1-3 are both closed, and the power supply 110 supplies power to the first storage device 120 through the closed first relay normally open contact J1-3. Meanwhile, the first normally open contact J1-1 of the first relay is closed, and the other path is provided for supplying power to the first relay coil J1-S of the first relay. At this time, the first switch S1 is released, and the first relay is also in the energized state, and power is maintained to the first storage device 120. Meanwhile, the first relay normally-closed contact J1-2 is disconnected, and the second relay coil cannot be electrified under the condition that the second switch S2 is pressed, so that the second relay normally-open contact J2-1 and the second relay normally-open contact J2-3 cannot be closed, power cannot be supplied to the second storage device 130, and the two storage device power supply circuits are interlocked. The main board 150 can only read the operating system and the application program in the powered storage device, that is, the main board 150 selects the operating system and the application program in the first storage device 120.
Similarly, when the second switch S2 is closed, the power supply 110 does not supply power to the first storage device 120, and only supplies power to the second storage device 130 and maintains the power supply state. At this time, the main board 150 selects the operating system in the second storage device 130 that is powered on.
In addition, after the first switch S1 is pressed, the first storage device 120 is kept in the power supply state, and power is not supplied to the second storage device 130 even if the second switch S2 is pressed, so that power supply of the storage device is prevented from being disturbed.
When the operating system in the first storage device 120 is used, it is necessary to shut down and restart the terminal first when the operating system in the second storage device 130 is replaced with the operating system.
It should be noted that in the embodiment of the present application, other functions of the terminal device, such as a computer, are not affected.
