It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic diagram of a dual operating system in an embodiment of the present invention, which is applicable to a case where the dual operating system operates. As shown in fig. 1, the dual operating system 100 of the present embodiment specifically includes: operating system switching device 110, external shared device 120, state switching key 130, first operating system 140 and second operating system 150, each of first operating system 140 and second operating system 150 comprising at least one independent memory (e.g., memory 141 and memory 151) and at least one independent processor (e.g., processor 142 and processor 152).
Each operating system is provided with an independent memory and an independent processor, namely, the data of each operating system is processed by the respective processor and stored in the respective memory, so that the data is stored in different memories, the data isolation of each operating system is ensured, at the moment, if the information of one operating system is leaked, the data of the other operating system is not influenced because the data of the other operating system is stored in other memories, and the data security of the other operating system is ensured.
The data of each operating system is processed by the respective processor, so that the operating systems can run independently, and when one operating system controls the external shared equipment, the other operating systems still run normally. Therefore, when the next operating system switching is carried out, the operating system which still normally runs can be switched to control the external shared equipment, the external shared equipment is ensured to be always controlled by the operating system which normally runs, the seamless switching of the operating system is realized, and a user cannot perceive the external shared equipment.
Two sets of operating systems are respectively operated by two independent hardware carriers, software resources are operated independently and cannot be accessed mutually, access between the two operating systems can be safely isolated, and the two hardware carriers realize switching between the two systems by sharing external shared equipment.
It should be noted that the attribute information (e.g., model number) of the independent memories included in different operating systems may be the same or different. The attribute information of the independent processors included in different operating systems may be the same or different.
The os switching device 110 is connected to the first os 140, the second os 150 and the external shared device 120, respectively, and the os switching device 110 is configured to control the external shared device 120 to be connected to the first os 140 or control the external shared device 120 to be connected to the second os 150.
Specifically, the os switching device 110 is used for gating the connection between the external shared device 120 and the first os 140, or gating the connection between the external shared device 120 and the second os 150, that is, for gating which os the external shared device 120 is connected to, so as to enable the switching os to establish a communication connection with the external shared device 120, thereby achieving the effect of switching the os.
And an external common device 120 for implementing a matching function according to independent control of the first operating system 140 or the second operating system 150.
Specifically, the external common device 120 includes a plurality of function devices to enable the operating system to control and implement functions.
The state switching key 130 is connected to the first operating system 140 and the second operating system 150, respectively, and is configured to switch the state of the first operating system 140 or switch the state of the second operating system 150. Illustratively, the state switching key is a switch key.
Specifically, the state switching button 130 is used to switch the state of the operating system. The state of the operating system may include at least one of: a power-on state, a wake-up sleep state, a call state, a switching state and the like.
The embodiment of the invention can realize independent operation without mutual influence of two operating systems by arranging two operating systems with independent memories and independent processors, and simultaneously, the data of the two operating systems are separately isolated and stored, thereby solving the problems that the effective isolation of the data cannot be ensured in the prior art, the information of one system is leaked, and the information of the other system is unsafe, ensuring the isolated storage of the data, improving the safety of the data, and simultaneously controlling the switching between the two operating systems by the operating system switching device.
In fact, the operating systems may be directly connected to each other. Optionally, as shown in fig. 2, a plurality of general input/output interfaces of the first operating system 140 are respectively connected to a plurality of general input/output interfaces of the second operating system 150, and the first operating system 140 is configured to determine a state of the second operating system 150 through the general input/output interfaces of the second operating system 150; the second operating system 150 is used for determining the state of the first operating system 140 through the general input output interface of the first operating system 140; the os switching unit 110 is configured to obtain a system switching instruction generated by the first os 140 and control the external shared device 120 to connect to the first os 140, or obtain a system switching instruction generated by the second os 150 and control the external shared device 120 to connect to the second os 150.
It should be noted that fig. 2 only schematically illustrates that the gpio interface of the first operating system 140 is connected to the gpio interface of the second operating system 150, and there is no limitation that only one gpio interface of the first operating system 140 is connected to one gpio interface of the second operating system 150. The first operating system 140 and the second operating system 150 may be connected through a plurality of general purpose input/output interfaces, for example, the number is 10, and this may be set according to needs, and the embodiment of the present invention is not limited specifically.
Specifically, the gpio interface is used to establish a connection between the first operating system 140 and the second operating system 150, and is also used to characterize the state of the operating systems.
Illustratively, the first operating system 140 and the second operating system 150 each include a plurality of general input/output interfaces B0, B1, B2, B3, B4, B5, and B6. It should be noted that, if a general input/output interface is used as an input end of the first operating system, the general input/output interface is correspondingly used as an output end of the second operating system. That is to say, the gpio interface corresponding to each status bit needs to be designed as an input end of an operating system and an output end of another operating system in hardware, so that the operating system having the gpio interface as the input end can obtain the status of the operating system having the gpio interface as the output end through the gpio interface. For example, the state bit B0 (e.g., the GPIO0) is that when the first operating system is not powered on, the GPIO0 of the first operating system outputs a pull-down signal, and after the first operating system is powered on, the GPIO0 outputs a pull-up signal, and the corresponding connected GPIO0 of the second operating system can acquire the state of the signal output by the GPIO0 of the first operating system. Wherein:
b0 is used to indicate the on/off state of the first operating system 140 and B1 is used to indicate the on/off state of the second operating system 150. The method comprises the following steps:
b0 is 0, indicating that the first os 140 is in the power-off state;
b0 is 1, indicating that the first operating system 140 is in a boot-up complete state;
b1 is 0, indicating that the second operating system 150 is in the power-off state;
b1 is 1, indicating the boot complete status of the second operating system 150.
For example: bytes of B0 and B1 are:
00, indicating that both the first operating system 140 and the second operating system 150 are in a shutdown state;
01, indicating the power-on completion status of the first operating system 140 and the power-off status of the second operating system 150;
10, indicating the power-on state of the second operating system 150 and the power-off state of the first operating system 140;
11, indicating that both the first operating system 140 and the second operating system 150 are in a boot-up complete state.
It should be noted that, if the priority of the first os is higher than that of the second os, the bytes of B0 and B1 are: 10 this state is not present. If the priority of the first os is lower than that of the second os, the bytes of B0 and B1 are: 01 this state is not present.
B2 is used to indicate a wake sleep state for the first operating system 140 and B3 is used to indicate a wake sleep state for the second operating system 150. The method comprises the following steps:
b2 is 0, which indicates the first OS 140 is in a sleep state;
b2 is 1, indicating that the first os 140 is awake;
b3 is 0, indicating the sleep state of the second operating system 150;
b3 is 1, indicating the wake state of the second operating system 150.
B4 is used to indicate the incoming call state of the first operating system 140, and B5 is used to indicate the incoming call state of the second operating system 150.
The method comprises the following steps:
b4 is 0, indicating that the first os 140 is not in the middle of a call or is over;
b4 is 1, which indicates that the first operating system 140 is calling and in the middle of a call;
b5 is 0, indicating that the second operating system 150 is not in the middle of a call or the call is over;
b5 is 1, which illustrates the second operating system 150 calling and in the middle of a call.
B6 is used to indicate the switching state of the first operating system 140 and the switching state of the second operating system 150. The method comprises the following steps:
b6 is 0, which indicates that the current device is in the first operating system 140 mode and the external shared device 120 has switched to the control of the first operating system 140;
b6 is 1, which indicates that the current device is in the second os 150 mode and the external shared device 120 has switched to the control of the second os 150.
In addition, there is a general input/output interface that represents other states of the operating system, and thus, the embodiment of the present invention is not particularly limited.
The GPIO controller is an I/O port device which is internally arranged in both a processor (chip) of the first operating system and a processor of the second operating system, can set an Input mode or an Output mode, can acquire an external signal when the Input mode (Input) is set, and can Output a pull-up signal or a pull-down signal when the Output mode (Output) is set. Generally, data transmitted between the dual operating systems only includes 0 and/or 1, the data transmitted through one GPIO only includes 0 or 1, and a plurality of GPIOs are combined to form a state controller (i.e., the aforementioned state bit) for controlling the dual operating systems, which can ensure that the data of the dual operating systems are safely isolated and the basic functions between the dual systems are normally used.
It should be noted that the general input/output interface may also be used to transmit data between the first operating system and the second operating system, so as to implement data interaction between the first operating system and the second operating system. Therefore, data transmission exists between the first operating system and the second operating system, and the connection between the two operating systems is guaranteed. For example, when switching to one operating system, the operating system receives the setting parameters of the external shared device modified by the user and transmits the setting parameters to another operating system to modify the setting. Therefore, switching of the operating systems is avoided, the situation that the setting parameters of the external shared equipment modified by a user are also switched when the operating systems are switched is avoided, the problem that the setting parameters of the modified external shared equipment before and after switching are not uniform cannot be guaranteed, switching of the operating systems which are not sensed by the user is achieved, and seamless switching is achieved.
Therefore, the first operating system and the second operating system can respectively determine the states of other operating systems through respective universal input/output interfaces, the high and low levels of the universal input/output interfaces can be changed through the states of the first operating system and the second operating system, the states of the operating systems can be updated, meanwhile, communication can be carried out through the universal input/output interfaces, the consistency of the setting parameters of external shared equipment is guaranteed, the stability of the operating systems is improved, and the use experience of users is improved.
In addition, each operating system may generate a system switching command according to the state of the operating system or the state of another operating system, and the system switching command may be input to the operating system switching device so that the operating system switching device controls the switching of the operating system to connect to the external shared device.
The system that generates the system switching command may be an operating system currently connected to the external shared device, or may be a pre-configured operating system with a high priority.
In fact, the dual operating system provided by the embodiment of the present invention does not have a separate controller dedicated to controlling the operating system switching device to switch the operating systems, and thus, the operation of controlling the switching of the operating system switching device can be implemented by each operating system, or only by one operating system (e.g., the first operating system) with the highest priority.
Alternatively, as shown in fig. 3, the operating system switching device 110 includes an electronic switch circuit 111; the electronic switch circuit 111 is respectively connected with the first operating system 140, the second operating system 150, and the external common device 120; specifically, the electronic switch circuit 111 is configured to gate a connection path between the first operating system 140 and the external shared device 120, or gate a connection path between the second operating system 150 and the external shared device 120, according to the system switching instruction.
Specifically, an electronic switching circuit refers to a circuit having two states, on and off. Illustratively, the electronic switching circuit may be a logic gate circuit, a triode circuit, a bistable flip-flop, or the like.

The function key may be triggered in specific ways such as setting the number of times and/or setting the duration, which is not limited in this embodiment of the present invention. Illustratively, the function key may be a keyboard.
The earphone and the earphone can be used for converting the electrical data received from the connected operating system into sound and playing the sound to the user in the incoming call process or the sound playing process.
The microphone is used for converting the voice sent by the user into electric data in the incoming call process or the voice recording process, and sending the electric data to the connected operating system for subsequent operation. The microphone may be an earphone microphone or a separate microphone.
In addition, the external shared device may also include other devices, such as a camera, a volume adjustment button, a speaker, a mouse, a usb disk, and the like. In this regard, the embodiments of the present invention are not particularly limited.

The first peripheral device controller 141 and the second peripheral device controller 151 are each configured to control the external shared device 120. The first internal memory 143 and the second internal memory 153 are both referred to as memories. The first flash memory 144 and the second flash memory 154 are both nonvolatile registers for long-term storage of data of the operating system, such as program data.

Illustratively, the satellite communication module is an all-satellite-communication Beidou radio frequency module. The satellite communication is communication between radio communication stations on earth using a satellite as a relay. The talkback communication refers to the simplex communication of point-to-point/multipoint within a small range, namely only one device occupies the frequency at one moment, and the same frequency interference is hardly considered, so that higher transmitting power can be used for obtaining a longer communication distance.

The receiver needs to select a signal of a specific code pattern among a plurality of signals, and other signals cannot be demodulated due to mismatch of the code patterns. Therefore, the data can be accurately received and demodulated by the corresponding receiver, and data transmission is realized. Illustratively, the CDMA communication module is a CDMA rf transceiver module. The encryption module is used for encrypting data, wherein the data comprises data to be transmitted and data to be stored. In addition, the second operating system may have a custom secure operating system built in.
Specifically, the android operating system is used for realizing an operating system of a basic function, the safe operating system is used for being independent of the android operating system, the safety of data is guaranteed, when the android operating system goes wrong, the safe operating system replaces the android operating system to control external shared equipment, and the stability of the local equipment is improved.
In a specific example, as shown in fig. 7, the dual operating system 100 includes an operating system switching device 110, an external shared device 120, a state switching key 130, a first operating system 140, and a second operating system 150. Fig. 7 shows, by way of example only, specific modules included in each unit, but is not limited thereto. For example, the first operating system 140 may further include a USB interface and a functional module, and the second operating system 150 may further include a USB interface. Meanwhile, the first communication unit 145 may include a cellular network communication module, a satellite communication module, and an intercom communication module. The second communication unit 155 may include a code division multiple access communication module and an encryption module.
The connected gpio interface of the first operating system 140 and the gpio interface of the second operating system 150 can be used as a state controller, and both the first operating system 140 and the second operating system 150 can determine the states of other operating systems according to the state identifier (such as the aforementioned B0, B1, B2, etc.) of the state controller, and can generate a system switching instruction according to the states to control the connection path between the external shared device and the operating system.
In a particular embodiment, the first operating system 140 has a higher priority than the second operating system 150. The trigger signal associated with the state switch key and the system switch key may be controlled by the first operating system 140. The power-on and power-off sequence is that the operating system with high priority is powered on first and then powered off. The first operating system 140 is responsible for controlling the sequence of power on and power off, while the second operating system 150 is not involved in the operation of power on and power off, i.e., not concerned with the switch design concept.
It should be noted that fig. 6 and fig. 7 are the same as fig. 2, and only show that the gpio interface of the first operating system 140 is connected to the gpio interface of the second operating system 150, and there is no limitation that only one gpio interface of the first operating system 140 is connected to one gpio interface of the second operating system 150.
Example two
Fig. 8 is a flowchart of a working state control method applicable to the dual operating systems provided in the embodiment of the present invention, where the method may be executed by any one of the dual operating systems provided in the embodiment of the present invention, and specifically, may be executed by the first operating system. The apparatus can be implemented in software and/or hardware, and can be generally integrated into an electronic device. As shown in fig. 8, the method specifically includes:
s110, determining the type of a state switching instruction according to the triggering mode of the state switching key and the incoming call state of the dual-operation system; the types of the state switching instructions comprise a power-on/off state switching instruction and a wake-up sleep state switching instruction.
The above description of the embodiments can be referred to for the status switching key, the dual operating system, the first operating system, the second operating system, the operating system switching device, and the like.
The first operating system can be a safe operating system or an android operating system; the second operating system may be a secure operating system or an android operating system. The first operating system and the second operating system may be the same or different. In addition, the first operating system and the second operating system may also be other operating systems, and thus, embodiments of the present invention are not particularly limited.
Specifically, the state switching key may have a plurality of triggering modes, and specifically, the type of the generated instruction may be determined according to the triggering mode of the user. Specifically, the triggering manner may include triggering time, triggering times, and the like.
Illustratively, if the user continuously presses the state switching key for 1 second, the on/off state switching instruction is determined to be generated.
The on-off state switching instruction is used for switching the on-off state of the first operating system and switching the on-off state of the second operating system.
Illustratively, if the user clicks the state switching key, it is determined to generate the wake-up sleep state switching instruction.
The wake-up sleep state switching instruction is used for switching a wake-up sleep state of the first operating system and switching a wake-up sleep state of the second operating system.
Optionally, the first operating system is further configured to control the operating system switching device to switch the operating system. The first operating system can generate a state switching instruction according to the configuration, and control the operating system switching device to control the external shared device to be connected with the first operating system or control the external shared device to be connected with the second operating system.
And S120, switching the states of the dual operating systems according to the type of the state switching instruction, the state of the first operating system, the state of the second operating system and the switching state of the operating system switching device.
The states of the operating system include an on/off state, a wake-up sleep state, and a talk state.
The switching state of the operating system switching means is used to indicate the current operating system of the connection with the external common device. The switching state of the operating system switching device comprises the first operating system or the second operating system.
In practice, the first operating system and the second operating system are both connected to the control line of the external shared device, and at the same time, the first operating system can control the external shared device by executing the first driver, and at the same time, the second operating system can control the external shared device by executing the second driver. The operating system switching means switches the connection object of the data line of the external common device. When the switching state of the operating system switching device is a first operating system, a connecting passage between the first operating system and a data line of the external public equipment is in a communicating state; when the switching state of the operating system switching device is the second operating system, the connection path between the second operating system and the data line of the external common device is in a connected state.
The existing operating system switching device is a toggle switch, and the anti-shake performance of a circuit is poor. In this embodiment, the os switching device is a physical button, and the user can change the connection state of the data lines of all the external common devices by pressing the physical button. Illustratively, the user changes the connection state of the data line of the external shared device by pressing a switch program in the trigger first operating system. The state value of the operating system switching device is saved in the GPIO (B6). Specifically, when B6 is set to 0, the data line of the external shared device remains connected to the first os; when the toggle state B6 is set to 1, the data line of the external common device remains connected to the second operating system.
Specifically, the first operating system determines the switching state, the wake-up sleep state and the switching state of the operating system switching device of the second operating system through the level state of the general input/output interface connected with the second operating system; the second operating system determines the switch state, the awakening sleep state and the switching state of the operating system switching device of the first operating system through the level state of the general input/output interface connected with the first operating system.
Optionally, before switching the state of the operating system according to the type of the state switching instruction, the state of the first operating system, the state of the second operating system, and the switching state of the operating system switching device, the method further includes: acquiring the state of the second operating system according to the general input/output interface of the first operating system; acquiring the state of the first operating system according to a general input/output interface of the second operating system; and the plurality of general input/output interfaces of the first operating system are respectively connected with the plurality of general input/output interfaces of the second operating system.
As the foregoing example, the states of the first operating system and the second operating system may be determined by referring to the level states of the plurality of general input/output interfaces, such as B0, B1, B2, B3, B4, B5, and B6 in the above embodiments, respectively.
The first operating system and the second operating system are connected by a plurality of general input and output interfaces. The first operating system can acquire the state of the general input/output interface connected with the second operating system through the general input/output interface, and simultaneously, the first operating system can respectively acquire a plurality of state bits of the second operating system through the plurality of general input/output interfaces, and the plurality of state bits form the state information of the second operating system, so that the state information of the second operating system is determined.
Similarly, the second operating system may obtain the state of the gpio interface connected to the first operating system through the gpio interface, thereby determining the state information of the first operating system.
The first operating system and the second operating system can be normally connected by configuring the general input/output interface and realizing the communication between the first operating system and the second operating system through the general input/output interface, and meanwhile, the first operating system and the second operating system can mutually acquire the states of each other through the general input/output interface, so that the correct switching operation of the operating systems is realized.
Optionally, the priority of the first operating system is higher than the priority of the second operating system.
The first operating system with high priority can generate a system switching instruction to control the operating system switching device to switch the operating systems, receive the instruction generated by the state switching key and control the second operating system with low priority to change the state. At this time, the second os cannot generate a system switching command to control the os switching device to switch the os, and cannot receive a command generated by the state switching key. Meanwhile, when the priority of the first operating system is high, the execution sequence is different in the process of powering on and powering off or in the process of waking up the sleep.
Optionally, the state switching instruction is a power on/off state switching instruction, and the power on/off state switching instruction is generated by triggering a state switching key by a user;
the switching the state of the dual operating system according to the type of the state switching instruction, the state of the first operating system, the state of the second operating system and the switching state of the operating system switching device includes:
if the first operating system is determined to be in a shutdown state and the second operating system is determined to be in a shutdown state, sequentially starting the first operating system and the second operating system, and updating the state of the first operating system and the state of the second operating system to be in a startup state;
if the first operating system is determined to be in the power-on state, the second operating system is determined to be in the power-on state, and the switching state of the operating system switching device is determined to be the second operating system, the second operating system is closed, and the state of the second operating system is updated to be in the power-off state;
if the first operating system is determined to be in the starting-up state and the switching state of the operating system switching device is determined to be the first operating system, displaying a power-on/off option on a display screen through the first operating system, switching the state of a target operating system pointed by a power-on/off instruction according to the received power-on/off instruction input by a user, and updating the state of the target operating system.
In fact, the power on/off sequence of the dual operating system is: when starting up, the operating system with high priority is started up first, and the operating system with low priority is started up later; when the system is shut down, the operating system with low priority is shut down first, and the operating system with high priority is shut down later.
Meanwhile, when the operating system completes the startup and shutdown, the state can be updated correspondingly, specifically, the state can be a high-low state for updating the level of the general input/output interface, and the on/off of the state indicator lamp can be controlled.
In a specific example, as shown in fig. 9, the boot flow diagram of the dual operating system includes:
s131, the first operating system is started.
S132, judging whether the first operating system is started up completely, if so, executing S134, otherwise, executing S133.
Specifically, the manner of determining that the first operating system is completely booted may be to check a status bit of the first operating system (e.g., B0), or to determine that the first operating system is completely booted when the first operating system is normally running.
S133, waiting for the completion of the boot of the first operating system.
For example, the determination operation may be performed every 1 second.
S134, the second operating system is started.
S135, judging whether the second operating system is started up completely, if so, executing S137, otherwise, executing S136.
Specifically, the completion of booting the second operating system may be determined by checking the status bit of the second operating system (e.g., B1)
S136, waiting for the completion of the boot of the second operating system.
And S137, updating the on-off states of the first operating system and the second operating system.
For example, the on and off of status indicator lights of the first operating system and the second operating system are updated.
It is understood that the first os has a higher priority than the second os, so that the first os is powered on before the second os is powered off, and there is no state where the first os is powered off and the second os is powered on. The first operating system may control the powering on and powering off of the second operating system.
When the switching state of the operating system switching device is the second operating system, the second operating system can only control the own power on and off, and at the moment, the second operating system in the power on state is powered off when a power on and off instruction is detected.
When the switching state of the operating system switching device is the first operating system, the first operating system may control its on/off state and the on/off state of the second operating system, and thus, the user needs to further select at least one of the shutdown state of the first operating system and the on/off state of the second operating system.
At this time, if the first operating system is started, the second operating system is shut down, options of the first operating system for shutting down and the second operating system for starting up are displayed on the display screen, a user can select any option, and when the user selects a shutdown instruction of the first operating system, the first operating system is shut down; and when the user selects the starting-up instruction of the second operating system, the second operating system is started up.
If the first operating system is started, the second operating system is started, options of the first operating system and the second operating system are displayed on a display screen, a user can select any option, when the user selects a closing instruction of the first operating system, the second operating system is shut down, and after the second operating system is shut down, the first operating system is shut down; and when the user selects a closing instruction of the second operating system, the second operating system is shut down.
Optionally, the switching the state of the target operating system pointed by the power on/off instruction according to the received power on/off instruction input by the user, and updating the state of the target operating system include: if the power-on/off instruction is determined to be a closing instruction of the first operating system and the second operating system is in a power-on state, sequentially closing the second operating system and the first operating system, and updating the state of the second operating system and the state of the first operating system to be in a power-off state; if the power-on/off instruction is determined to be a power-off instruction of the first operating system and the second operating system is in a power-off state, the first operating system is turned off and the states of the first operating system are all updated to be in the power-off state; if the power-on/off instruction is determined to be a closing instruction of the second operating system, closing the second operating system, and updating the state of the second operating system to a power-off state; and if the power-on/off instruction is determined to be the power-on instruction of the second operating system, starting the second operating system, and updating the state of the second operating system to be the power-on state.
It should be noted that, in the boot process, if the first operating system is powered off and the second operating system is powered off, the user starts the first operating system first and then the second operating system by triggering the power on/off instruction generated by the state switching key, and there is no option for the user to select which operating system to power on. That is, when the computer is started, the first operating system is started first, and then the second operating system is started, so that the situation that any operating system is started only does not exist. If only the first operating system is desired to be turned on and the second operating system is turned off, the second operating system may be selected to be turned off after both the first operating system and the second operating system are turned on.
In a specific example, as shown in fig. 10, a complete shutdown flow chart of the dual operating system includes:
and S141, shutting down the second operating system.
And S142, judging whether the shutdown of the second operating system is completed, if so, executing S144, and otherwise, executing S143.
S143, the shutdown of the second operating system is waited to be completed.
And S144, shutting down the first operating system.
S145, judging whether the first operating system is shut down completely, if so, executing S147, otherwise, executing S146.
S146, waiting for the shutdown of the first operating system to be completed.
And S147, updating the on-off states of the first operating system and the second operating system.
It should be noted that if only the second operating system needs to be shut down, only part of the flow in S141-S143 may be performed. If the second operating system is in the shutdown state, and the shutdown instruction of the first operating system is detected, only the first operating system needs to be shut down, and only part of the flow in S144-S147 may be performed.
By configuring the shutdown process of the operating system, the switching of the startup and shutdown states of the operating system can be accurately realized.
On the other hand, if the state switching instruction is a wake-up sleep state switching instruction; the awakening dormant state switching instruction is generated by triggering a state switching key by a user; optionally, the switching the state of the operating system according to the type of the state switching instruction, the state of the first operating system, the state of the second operating system, and the switching state of the operating system switching device includes: if the first operating system and the second operating system are both determined to be in the dormant state and the switching state of the operating system switching device is the first operating system, waking up the first operating system and updating the state of the first operating system to be in the awakening state; if the first operating system and the second operating system are both determined to be in the dormant state and the switching state of the operating system switching device is determined to be the second operating system, sequentially waking up the first operating system and the second operating system and updating the states of the first operating system and the second operating system to be in the awakening state; and if the first operating system and the second operating system are both in the wake-up state, switching the target operating system pointed by the switching state of the operating system switching device into the sleep state, and updating the state of the target operating system into the sleep state.
Specifically, waking up the os actually means that a processor of the os enters a normal operating state from a sleep or standby state. The target operating system is switched to a dormant state, which actually means that a processor of the operating system enters a dormant or standby state from a normal working state. The sleep or standby state is used to reduce power consumption of the operating system, save energy, and the like.
When the switching state of the os switching device is the second os, the second os needs to be woken up, and at this time, the first os and the second os are sequentially woken up.
It can be understood that the first operating system receives the wake-up sleep state switching instruction of the state switching key, and wakes up the second operating system based on the wake-up sleep state switching instruction, so that it is detected that the user triggers the power on/off key to generate the wake-up sleep state switching instruction, and the first operating system needs to be woken up first, and then the second operating system needs to be woken up. During this process, the user does not feel that the first operating system is woken up.
In fact, if the first operating system or the second operating system is turned on for a long time and does not operate, the first operating system or the second operating system enters an automatic sleep mode, and if the first operating system or the second operating system is turned on for a long time (the time length can be set as required), the first operating system or the second operating system enters a sleep state, and if the first operating system or the second operating system is turned on for a long time and does not sleep, the first operating system or the second operating system is always in an awakening state.
The first operating system and the second operating system can enter a dormant state when not operating for a long time. If the normally-on hibernation-free module is arranged, the first operating system and the second operating system are still in the awakening state after being not operated for a long time.
In a specific example, as shown in fig. 11, a flowchart of the dual operating system for implementing wake-up sleep switching by the user triggering the state switching key includes:
and S151, starting the dual operating systems.
The wake-up sleeping state refers to a normal working state and a standby state after the first operating system and the second operating system in the dual operating systems are both started.
S152, receiving a wake-up dormant state switching instruction generated by a user triggering state switching key.
S153, judging whether the first operating system is in an awakening state, if so, executing S154; otherwise, S159 is executed.
S154, judging whether the second operating system is in an awakening state, if so, executing S155; otherwise, S156 is performed.
S155, the target os to which the switching state of the os switching apparatus is directed is switched to the hibernation state, and the state of the target os is updated to the hibernation state.
If the target operating system pointed by the switching state of the operating system switching device is the first operating system, the first operating system is switched into the dormant state, and the state of the first operating system is updated into the dormant state.
And if the target operating system pointed by the switching state of the operating system switching device is the second operating system, switching the second operating system into the dormant state, and updating the state of the second operating system into the dormant state.
S156, judging whether the switching state of the operating system switching device is the first operating system, if so, executing S157; otherwise, S158 is executed.
S157, switch the first operating system to the hibernation state, and update the state of the first operating system to the hibernation state.
S158, switching the second operating system to an awake state, and updating the state of the second operating system to the awake state.
S159, judging whether the second operating system is in the awakening state, if so, executing S160; otherwise, S163 is executed.
S160, judging whether the switching state of the operating system switching device is the first operating system, if so, executing S162; otherwise, S161 is executed.
S161, switching the first operating system to an awakening state, and updating the state of the first operating system to the awakening state.
S162, switching the second operating system to a dormant state, and updating the state of the second operating system to the dormant state.
S163, judging whether the switching state of the operating system switching device is the first operating system, if so, executing S165; otherwise, S164 is executed.
S164, sequentially waking up the first operating system and the second operating system, and updating the states of the first operating system and the second operating system to be a wake-up state.
S165, switching the first operating system to be in an awakening state, and updating the state of the first operating system to be in the awakening state.
The state switching key is used for triggering to realize the awakening and sleeping switching of the operating system, so that the conversion of the awakening and sleeping state of the operating system can be accurately realized.
If the state switching instruction is a wake-up sleep state switching instruction; the awakening dormant state switching instruction is generated by triggering through an incoming call; optionally, the switching the state of the operating system according to the type of the state switching instruction, the state of the first operating system, the state of the second operating system, and the switching state of the operating system switching device includes: if the first operating system and the second operating system are determined to be in the dormant state, the first operating system receives an incoming call, and the switching state of the operating system switching device is the first operating system, waking up the first operating system, updating the state of the first operating system to be in the awakening state, and controlling a display screen in the external shared equipment to display an incoming call interface through the first operating system; if the first operating system and the second operating system are determined to be in the dormant state, the first operating system receives an incoming call, and the switching state of the operating system switching device is the second operating system, waking up the first operating system, updating the state of the first operating system to be in the awakening state, switching to the first operating system through the operating system switching device, and controlling a display screen in the external shared device to display an incoming call interface through the first operating system; if the first operating system and the second operating system are both in an awakening state, the second operating system receives an incoming call, and the switching state of the operating system switching device is the first operating system, the second operating system is switched to the second operating system through the operating system switching device, and the second operating system controls a display screen in the external shared equipment to display an incoming call interface; if the first operating system and the second operating system are both in the awakening state, the first operating system receives an incoming call, and the switching state of the operating system switching device is the second operating system, the first operating system is switched to the first operating system through the operating system switching device, and the first operating system controls a display screen in the external shared equipment to display an incoming call interface; if the first operating system is in a call and the second operating system is in a dormant state, waking up the second operating system, and switching to the second operating system through the operating system switching device after the first operating system is hung up; if the second operating system is in a call and the first operating system is in a dormant state, the first operating system is awakened, and the second operating system is switched to the first operating system through the operating system switching device after being hung up.
The operating system in the dormant state, which receives the incoming call, needs to be awakened and needs to control the display screen through the operating system to display the incoming call interface.
Because the priority of the first operating system is high, the first operating system generates a system switching instruction to control the operating system switching device to switch the operating systems.
When the switching state of the operating system switching device is the first operating system and the second operating system needs to be awakened, the second operating system and the first operating system need to be awakened sequentially at the moment, the states of the first operating system and the second operating system are updated to be the awakening state, and the operating system switching device is used for switching to the second operating system. That is, after the second operating system is awakened by the incoming call, the first operating system needs to be awakened, and the operating system switching device is controlled by the first operating system to be switched to the second operating system. And after the second operating system is switched, the second operating system controls the display screen to display the incoming call interface.
If the second operating system is not required to be awakened, the second operating system is still in a dormant state and cannot be awakened.
In a specific example, as shown in fig. 12-13, a flowchart of a dual operating system for implementing wake-up sleep switching triggered by an incoming call includes:
s171, starting up the dual operating systems.

And S176, switching the operating system pointed by the switching state of the operating system switching device into a target operating system of the incoming call, and controlling a display screen in the external shared equipment to display the incoming call interface through the target operating system.

s211, the dual operating systems are in a call.
The dual operating systems are in a call, which means that one of the dual operating systems is in a call.
S212, a call comes from the target operating system except the operating system in the call.
The first operating system is in a call, the second operating system calls, and the target operating system is the second operating system.
The second operating system is in a call, the first operating system calls, and the target operating system is the first operating system.
S213, judging whether the target operating system is in a dormant state, if so, executing S214; otherwise, S215 is performed.
S214, the target operating system is switched to the awakening state, and S215 is executed.
And if the second operating system is in a dormant state, switching the second operating system into an awakening state.
And if the first operating system is in a dormant state, switching the first operating system into an awakening state.
S215, the target operating system is busy and waits.
S216, after the operating system in the call is hung up, the operating system pointed by the switching state of the operating system switching device is switched to the target operating system.

After the call of the second operating system in the call is suspended, the operating system to which the switching state of the operating system switching device is directed is switched to the first operating system, and the first operating system controls the external shared device.
When one operating system is in a call, the other operating system calls to wake up and sleep switch the operating systems, so that the switching of the wake up and sleep states of the operating systems can be accurately realized, and the external shared equipment is controlled by the incoming operating system after the call is finished, so that the call receiving operation can be quickly switched to the incoming operating system.
