Description

Operating system automatic restoration method, device, computer equipment and storage medium

Technical Field

The present invention relates to the field of system control, and in particular to an operating system automatic restoration method, device, computer equipment and storage medium.

Background technique

BIOS (Basic Input/Output System) is a basic input/output system. It plays a very important role in the computer system and is one of the core components. It can be said that it is a bridge or interface between computer hardware and software. It can provide the lowest-level hardware control program for the computer. Therefore, the performance of the motherboard depends largely on the BIOS on the motherboard.

WDT (Watchdog timer), also known as watchdog, is a timer circuit, which generally has one input and one output. When working normally, a signal is input at regular intervals to feed the dog and clear the WDT. If the dog is not fed within the specified time (generally when the program runs wild), the WDT timing is exceeded, and then a reset signal is given to the motherboard to reset it, and the system is reset and runs again.

Operating systems have methods for installation, backup, and restoration. There are many ways to install, such as using a system CD, network, USB flash drive, external software boot installation, etc. There are also many ways to backup, such as the system's own backup function, Clonezilla software, PE backup tools installed in USB flash drives, etc. There are also many ways to restore, such as the system's own restore function, Clonezilla software, one-click GHOST, etc.

In the field of industrial control, some equipment is unattended during the power-on process. The system settings and drivers running in different user environments are different. After the user has built the environment required for the system to run, a backup is usually required. If there is no backup, rebuilding the environment will waste a lot of time. If the system is backed up, professionals need to manually operate step by step to restore the operating system.

The technical solution of the present application sets a system automatic restoration count value to determine whether the current system is in a state where a restoration operation is required, and utilizes the effect of a watchdog to perform a restoration or restart operation, and performs corresponding accumulation or zeroing operations on the system automatic restoration count value according to the state at the time of restart, thereby enabling the system to have an automatic restoration function to ensure the stability of the system itself.

Next, the technical solution of the present application is described with specific embodiments.

Example 1

The technical solution of this embodiment is applied to the automatic restoration process of the operating system, and can be applied to general personal computers, smart terminals or other electronic devices with an operating system, wherein the operating system itself is not limited, and it can be a common operating system such as Linux, Win, Android, etc., or a simpler single-chip microcomputer system such as Ecos. When these systems are in operation, some failures often occur due to human or environmental factors. This embodiment monitors these operating systems to determine whether these operating systems need to be restored, and provides technical means for automatically restoring the operating system.

As shown in FIG1 , the operating system automatic restoration method of this embodiment includes:

Step S100, during the operating system startup process, determining the state of the system automatic restoration function.

In order to ensure that the operating system can be automatically restored, this embodiment will set a system automatic restore function. This function can determine its on or off status through a flag bit. The value is set in the BIOS (basic input and output system). When the operating system starts, it will first enter the BIOS. At this time, the status of the system automatic restore function can be directly read in the BIOS to determine whether the function is on or off.

The on/off status of the automatic restore function of the system can be manually set by an operator, or configured by means of a configuration file, etc.

Step S200: If the system automatic restoration function is turned on, the system automatic restoration count value is obtained, and the system automatic restoration count value is accumulated and calculated.

If the status of the system automatic restoration function is on, it means that the system automatic restoration conditions need to be monitored. In this embodiment, a system automatic restoration count value is set for this purpose. This value is accumulated by 1 every time the system is started and the system automatic restoration function is on.

The system automatic recovery count value is a value that records the number of abnormal system restarts. It can be understood that if there is a problem with the system, it will inevitably restart frequently, and the value will accumulate rapidly. If there is no problem with the system, the system will not restart frequently, then this value will be cleared when the system is restarted normally or shut down to ensure that there is no incorrect restoration.

In other words, if the system automatic restore function is turned off, there is no need to obtain the system automatic restore count value, and there is no need to perform the accumulation operation. At this time, the operating system will start directly.

After entering the BIOS, the system will also go through the PEI (Extensible Firmware Interface Pre-Initialization) stage and the DXE (Driver Execution Environment) stage in sequence. The judgment of the above-mentioned system automatic recovery function can be performed in the above two stages. For example, a judgment is performed in the PEI stage, and then it is determined whether to accumulate the system automatic recovery count value and whether to directly start the operating system later. Similarly, a judgment can also be performed in the DXE stage to determine whether the function is turned on.

It is also possible to perform two judgment operations in these two stages respectively. For example, in the PEI stage, determine whether the system automatic restore function is turned on, and accumulate the system automatic restore count value. After entering the DXE stage, determine whether the system automatic restore function is turned on again to determine whether to directly start the operating system.

Step S300: If the system automatic restoration count value is greater than a first preset value, a system restoration operation is performed.

In this embodiment, the system automatic restoration count value is obtained, accumulated, and the value is judged, mainly compared with the first preset value. If it is greater than the first preset value, the system restoration operation of the operating system is directly performed, and if it is less than the first preset value, the operating system is started.

Specifically, the first preset value can be set to any integer, for example, the first preset value is set to 3, and when the system automatic restoration count value is greater than 3, the system restoration operation will be performed. The first preset value can be set to a value including 3 to 8, such as 3, 4, 5, and other integers.

Among them, for each operating system, there will be backup data. During normal operation, these backup data will be saved in an isolated storage space. When the system restore operation is performed, the partition of the operating system will be hidden, and the system restore partition will be entered to call the system restore program and the stored backup operating system to restore the operating system.

That is, the system restore program and the backup operating system are usually hidden and will not be affected by operating system errors. When a system restore operation is needed, the system restore program and the backup operating system in the hidden partition will be activated before starting the operating system. In this way, the current erroneous operating system can be restored to the state of the backup operating system, thereby realizing the system restore operation.

In addition, for different times of restart, this embodiment can also use some prompting methods to inform the user that the current machine is in an abnormal state, such as notifying the user through the alarm sound of a light or a buzzer.

In actual situations, there may be only one system restart left before the system restore is triggered. However, the device is a closed device and there is no control panel for the operator to operate. In this case, the set LED can flash in different colors to indicate the current number of restarts, thereby indicating what abnormal state the device is in. Sometimes, the device is obviously in an abnormal state and may only need an abnormal restart to perform the restore operation, but it cannot be restarted because the conditions have not been met. At this time, this prompt can allow the user to perform some external interference to force the device to enter an abnormal restart, so that the device is "manually" restored.

Step S400, when the operating system is shut down or restarted normally, the system automatic restoration count value is reset to zero and then shut down or restarted.

Among them, the system will be shut down and restarted through normal procedures, or manually shut down or restarted by the operator. These are all normal shutdown and restart operations. At this time, before the shutdown or restart operation, the system automatic restoration count value will be reset to zero, and then the corresponding operation will be performed. In this way, the system automatic restoration count value will not be accumulated due to normal shutdown or restart.

As shown in FIG. 2 , this embodiment provides a process of a watchdog program monitoring an operating system, including:

Step S500, after the operating system is started, the watchdog program is started, and the watchdog time is set according to the automatic restoration count value of the system.

When the operating system starts normally, the watchdog program will be started. The watchdog program is a monitoring program. By setting the watchdog time and regularly resetting the watchdog state in the watchdog program according to the watchdog time, it can be determined whether the operating system is in a normal operating state.

For example, if the watchdog time is set to 1 second, a "feed the dog" operation is required in a 1-second period. This operation is to reset the watchdog status. There is a countdown timer in the watchdog program. Each time the "feed the dog" operation is performed, the timer will be reset and recalculated. As long as the reset signal is received before the countdown ends, it means that each "feed the dog" operation is carried out normally, which means that the operating system is operating normally.

Among them, the watchdog time needs to be set according to the system's automatic restoration count value.

As mentioned above, the system automatic recovery count value indicates the number of abnormal restarts of the operating system. Therefore, the more times and the larger the value, the more unstable the operating system is. However, in some scenarios, although the operating system may have problems, after several restarts, the operating system may solve the problem due to some other self-recovery mechanisms. However, during this period, the operating system may be a little sluggish. Therefore, it is necessary to appropriately extend the watchdog time according to the current system automatic recovery count value, that is, the watchdog time is extended as the system automatic recovery count value increases.

Specifically, when the system automatic recovery count value is 1, it means that there has been no abnormal restart. The 1 here is just 1 added during normal startup, so the watchdog time at this time can be a default time. If the system automatic recovery count value is 2, it means that an abnormal restart has occurred. The watchdog time at this time can be twice the original default time, and so on. If it is 3, it can be 3 times.

In addition, the watchdog time can also be in the form of a base time multiplied by a power of 2. For example, if the base time is 1 second, when the system automatically restores the count value to 1, the watchdog time is 2 to the 1st power seconds. When the system automatically restores the count value to 2, the watchdog time is 2 to the 2nd power seconds. And so on to determine the specific time. The unit can be microseconds in addition to seconds. The specific value, unit and actual calculation method can be satisfied as long as the watchdog time is positively correlated with the system automatically restored count value.

Step S600, if the watchdog state of the watchdog program is not reset before the countdown of the watchdog time ends, it is determined that the operating system is in an abnormal state, the operation of automatically restoring the system count value to zero is skipped, and the operating system is restarted.

If the watchdog program does not reset the watchdog state before the watchdog time countdown ends, it means that there is a problem with the operating system and it is not reset in time. At this time, the watchdog program will issue an instruction to restart the system and perform a system restart operation.

It can be understood that the restart caused by the watchdog program is an abnormal restart. Generally, a normal restart is a manual operation or a restart planned by some task scheduler. The restart of the watchdog program is because it does not receive the scheduled reset signal. It judges that there is a problem with the operating system and needs to be restarted to solve it. Therefore, it is an abnormal restart.

If it is a normal restart, the system will automatically restore the count value to 0 before completing the restart to ensure that the value does not accumulate.

An abnormal restart will skip the above reset operation, and the system automatically restores the count value after the restart is completed, and accumulates it in the above step S100, thereby completing the record of an abnormal restart.

As shown in Figure 3, combined with the entire step flow, it can be seen that when the device where the operating system is located is started, at the initial stage of entering the BIOS, it will determine whether the current operating system needs to be restored. If it needs to be restored, the operating system will not be entered at all, and the system restore operation can be performed directly at the beginning. If it does not need to be restored, the system can be entered directly, and with the help of the characteristics of the watchdog program, the operating system is monitored to determine the conditions for system restoration. As long as the conditions are met, the system can be automatically restored.

The solution of this embodiment can be applied to a variety of application scenarios, such as common household machines, etc., and can also be used in some devices without human-machine interaction interfaces, to ensure that these devices can also perform self-correction and automatic restoration in the case of no one operating or unattended, so as to ensure the stability of the device operation. Moreover, the method of this embodiment can be implemented in a pure software manner, without the need to redesign the mainboard structure, and can solve problems such as serious system crashes. As long as there is a backup system, the restart and restore operations can be automatically implemented. In addition, this application uses partition isolation to separate the operating system partition and the backup partition, ensuring that the two do not interfere with each other during actual operation, thereby ensuring the safety of the backup files.
