Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention, as shown in fig. 1, a CPU11 is a central processing unit (Central Processing Unit) capable of responding to an instruction generated by an automobile device and controlling execution content of a kernel in an operating system. The central control system 12 and the instrument system 13 of the automobile equipment are positioned on an application layer facing to a user, and containers are respectively arranged in the central control system 12 and the instrument system 13 so as to realize the starting of different systems; the middle GUI is an interface layer and is used for providing rich functional controls and exquisite interface design functions; the bottom layer of the system is an operating system 15, including the construction of a file system and the running of a driver, while the kernel is the core of the operating system, and can determine when the program operates on each piece of hardware.
The central control system and the meter system are called as business function classification, the latter meter time-sharing operation system is the meter system, and the central control time-sharing operation system is the central control system.
In order to reduce the waste of hardware resources, the meter system 13 and the central control system share one chip, and the meter system 13 and the central control system 12 are simultaneously mounted on one system, such as a linux system. However, when the meter system 13 is mounted in the linux system, there is a problem in that the start speed is slow when the meter system is started.
Based on the above problems, the method and the device for controlling the internal core to be in the deep sleep state when the automobile equipment is not used, when the first instruction for starting the instrument is received, different operations are executed according to the state information of the internal core, and when the state information of the internal core is in the deep sleep state, the internal core is directly controlled to be switched from the deep sleep state to the normal running state, so that the internal core does not need to carry out a complete initialization process, and the starting speed of the instrument is accelerated.
The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a schematic flow chart of an instrument starting method according to an embodiment of the present invention, where the method provided in the embodiment may be executed by a CPU, as shown in fig. 2, and the method in the embodiment may include:
s201, acquiring the state of the kernel when a first instruction for indicating to start the instrument is received.
In this embodiment, when the first instruction for starting the meter is received, the state of the kernel in the system may be acquired first, and the states of the kernel may be two, where the kernel is not initialized when the automobile is started for the first time; the second case is when the kernel is in a deep sleep state; when the states of the cores are different, the cores can be controlled to execute different operations.
S202, when the state of the kernel is a deep sleep state, controlling the kernel to be switched from the deep sleep state to a normal running state; the deep sleep state indicates that at least one application is in a suspended state and that no application in a foreground running state exists; the normal running state indicates that at least one application is in a foreground running state.
When the kernel is in the deep sleep state, the kernel is directly controlled to wake up from the deep sleep state, namely, the kernel is controlled to be switched from the deep sleep state to the normal state.
When the kernel is in a deep sleep state, at least one application in all applications is in a suspended state, and the other applications are in a termination state, namely in a killing state, and meanwhile, no application in a foreground running state exists. When the kernel is in a deep sleep state, the instrument time-sharing operating system is also in a power-on state.
The normal running state refers to that at least one application is in a foreground running state, and can also allow part of the applications to be in a suspended state or in a background running state.
In addition, when the state of the kernel is not initialized, the kernel is controlled to perform initialization operation.
When the state of the kernel is not initialized, the kernel can be controlled to perform initialization operation. The kernel is software in the system, and can realize process management, memory management, IO management, file management, network management and the like. Specifically, the kernel of the system may be loaded into memory and the initialization of the kernel checking hardware and circuit logic controlled to facilitate the completion of subsequent meter starts.
Before the initialization operation, hardware power-up is needed, such as power-up of an embedded single board CPU chip and power-up of an instrument time-sharing operating system.
The state of the kernel is in an uninitialized state and can be determined by whether an instruction for starting the instrument is received for the first time. If an instruction for starting the instrument is received for the first time, the state of the kernel is not initialized, after the kernel is controlled to perform initializing operation, the instrument is further started, and after the automobile equipment is not used, the kernel is controlled to be in a deep sleep state; if the instruction for starting the instrument is not received for the first time, the state of the kernel is a deep sleep state, and the kernel can be directly awakened from the deep sleep state.
S203, operating a first container corresponding to the instrument time-sharing operating system, starting the instrument time-sharing operating system through the first container, and displaying instrument information.
And after the kernel wakes up from the deep sleep state, executing a flow of the first container corresponding to the time-sharing operating system of the running instrument, so that instrument information can be displayed on an instrument screen.
S204, running a second container corresponding to the central control time-sharing operating system, starting the central control time-sharing operating system through the second container, and displaying a central control interface.
The method comprises the steps of displaying instrument information, controlling the central control time-sharing operating system to start through a second container corresponding to the central control time-sharing operating system through the second container, and displaying a central control interface.
After the time-sharing operating system of the control instrument is started, the central control time-sharing operating system can be continuously started. In general, when a user is using an automobile device, it is necessary to determine the running condition of the vehicle from information displayed by an instrument. The central control time-sharing operating system is usually used for running the entertainment device, and has lower requirement on the starting speed of the central control time-sharing operating system, so that the central control time-sharing operating system can be started continuously after the instrument time-sharing operating system is started.
The instrument time-sharing operating system and the central control time-sharing operating system share a kernel, wherein the instrument time-sharing operating system can be a linux operating system; the central control time-sharing operating system can be an Android operating system. When the kernel is in a deep sleep state, the instrument time-sharing operating system and the central control time-sharing operating system are both in a sleep state, so that the instrument time-sharing operating system and the central control time-sharing operating system can be realized only by running the second container when the central control time-sharing operating system is started.
In this embodiment, when the automobile is not used, the control kernel is in a deep sleep state, and when the instrument time-sharing operating system is started, if the kernel is in the deep sleep state, the kernel is directly awakened from the deep sleep state, and the steps of powering on hardware and initializing the kernel are not required to be executed, so that the process of starting the instrument is saved, the starting speed of the instrument time-sharing operating system is improved, and when the instrument time-sharing operating system is started, the central control time-sharing operating system can be continuously started. In practice, the method can realize the starting of the instrument process within 2 seconds and display of instrument data.
In some embodiments, the method further comprises:
and when a second instruction for indicating to turn off the meter is received, controlling the kernel to enter a deep sleep state.
In this embodiment, in order to switch the control core from the deep sleep state to the normal state, the control core needs to perform the deep sleep state when the vehicle is not in use. Specifically, when the vehicle is in use, the user can send a second instruction for indicating to turn off the meter, and when the CPU receives the second instruction, the CPU can enter a deep sleep state.
In practice, when the automotive device is powered on for the first time, the state information of the kernel is not initialized. When the automobile equipment is powered on for the first time and started, the automobile equipment can enter a deep sleep state when a second instruction of powering down the automobile is received, and then the automobile equipment can be directly awakened from the deep sleep state when the automobile equipment is powered on for the second time and subsequent times.
The kernel is controlled to enter the deep sleep state, so that the user can be conveniently and directly switched from the deep sleep state to the normal state when the user starts the instrument next time.
In some embodiments, controlling the kernel to enter a deep sleep state includes:
the control part is used for controlling the application in a suspended state and controlling the application which is outside the suspended state in a termination state in all the applications;
correspondingly, controlling the kernel to switch from the deep sleep state to the normal running state comprises the following steps:
controlling the kernel to wake up the part of the application in the suspended state.
When the control kernel enters the deep sleep state, part of the applications can be set to be in a suspended state and the rest of the applications can be set to be in a termination state, namely, a killing state according to the requirements of a user. By suspending part of the applications and killing the rest of the applications, the consumption of the CPU and the network pressure of the instrument time-sharing operating system are reduced, and the consumption of electric quantity in the deep sleep process is reduced. The application in the suspended state and the application in the terminated state may be determined according to actual situations, which is not limited herein.
Accordingly, when the control kernel wakes up from the deep sleep state, the kernel is ready and only needs to be controlled to switch to the normal running state and wake up the part of the application in the suspended state.
In some embodiments, the method further comprises:
and when the kernel is in the deep sleep state, periodically running the application in the suspended state so as to enable the application to be in the background running state.
Wherein, when the kernel is in a deep sleep state, the application in a suspended state also needs to run periodically. Wherein, the operation period can be preset, such as the operation period is 6 hours. When the CPU receives an instruction that the current moment sent by the timer meets the set running period, the CPU controls the kernel to run the application in the suspended state.
The background running state refers to a state that an application is in the background of an operating system and is running, that is, application codes are executed in the background system. The application entering the background running state can enter the suspended state again after being maintained for a period of time.
In some embodiments, the running the first container corresponding to the meter time-sharing operating system, starting the meter time-sharing operating system through the first container, and displaying meter information, including:
operating a first container corresponding to the instrument time-sharing operating system, and starting the instrument time-sharing operating system by operating a file in the first container;
and after the instrument time-sharing operation system is started, controlling the back light of the instrument screen to start, and displaying instrument information through the instrument screen.
When the instrument process is started, the files in the first container need to be run, wherein the files comprise display application programs, sound application programs and other related application programs, and the process of the instrument can be started by running the files.
When the kernel is in the deep sleep state, the first container corresponding to the instrument timesharing operating system is also in a termination running state. And, the first time the meter is started, the files in the first container also need to be run.
The instrument time-sharing operating system and the central control time-sharing operating system can be mutually isolated and independently operated through a container technology.
Further, when the kernel is in a deep sleep state, the instrument screen backlight is turned off. Therefore, after the meter is started, it is also necessary to backlight the meter screen so that meter information can be displayed on the screen.
In some embodiments, the method further comprises:
before the kernel enters a deep sleep state, saving instrument information displayed by the instrument time-sharing operating system,
the meter information includes: mileage information and oil amount information.
In addition, in order to facilitate quick start of the meter, meter information of the kernel before entering the deep sleep state can be stored. Specifically, meter information may be stored in RAM (Random Access Memory ) and the RAM is placed in a powered-on state. When the instrument is started next time, after the back light of the instrument starts, the instrument information can be directly read from the RAM and displayed on an instrument screen. The meter information here may be mileage information, oil amount information, or the like.
By storing the instrument information, the instrument information can be displayed quickly when the instrument is started next time.
In some embodiments, the first instruction is an instruction generated when an ACC gear of the automotive device is in an ON state; the second instruction includes an instruction generated when the ACC gear of the automotive device is in the OFF state.
When the user turns ON the ACC gear of the automobile equipment, the automobile equipment is powered ON, and the CPU receives a first instruction.
Conversely, when the ACC gear for turning the vehicle device is in the OFF state, the vehicle device is indicated as the down point, and the CPU will receive the second instruction.
In addition, the user can control the power-on or power-off of the automobile equipment through the automobile key, and correspondingly, the CPU can receive the first instruction or the second instruction.
Fig. 3 is a flow chart of another method for starting an instrument according to an embodiment of the present invention, as shown in fig. 3, where the method includes:
s301, executing step S302 when the ACC gear is detected to be in an ON state;
s302, judging whether the first power-on starting is performed; if yes, go to step S303; if not, executing step S304;
s303, initializing a Linux kernel;
s304, exiting the deep sleep state, entering a normal running state, and waking up the suspended application by the kernel;
s305, the first container operates, the back of the instrument screen is bright, and the instrument displays normally;
s306, the second container runs, and a central control time-sharing operating system is started;
s307, detecting that the ACC gear is in an OFF state;
s308, entering a deep sleep state, suspending part of applications, turning off the instrument screen backlight, and terminating the first container;
s309, detecting that the ACC gear is in the ON state again.
In practice, the meter start may be controlled according to the above-described execution steps.
According to the method, when the automobile is not used, the inner core is controlled to be in the deep sleep state, and when the instrument is started, if the inner core is in the deep sleep state, the inner core is directly awakened from the deep sleep state, the steps of hardware power-on and inner core initialization are not required to be executed, the process of starting the instrument is saved, and therefore the starting speed of the instrument is improved. In practice, the method can realize the starting of the instrument process within 2 seconds and display of instrument data.
On the basis of the above embodiments, the time when the kernel is in the deep sleep state may be set according to the frequency of the user using the automobile in consideration of the difference in the frequency of the user using the automobile device. Specifically, when the automobile equipment is powered down, the inner core can be controlled to enter a deep sleep state, the time of the inner core in the deep sleep state is counted, and when the counted result exceeds the preset time, the inner core is controlled to be in a state of stopping operation. For example, when the core is in the deep sleep state for 10 days, the core may be controlled to be in a state of stopping operation.
Through the operation, when the user uses the automobile frequently, the automobile can enter a deep sleep state, so that the instrument can be started quickly when the automobile is used next time; when the user does not use the automobile frequently, the user can exit the deep sleep state, and power consumption is reduced.
