[0002] With the rapid development of intelligent transportation technology, vehicle terminals are increasingly used in modern vehicles. Vehicle terminals are not only used for navigation, entertainment and communication, but also undertake multiple functions such as vehicle control and safety monitoring. However, in actual use, vehicle terminals may encounter various abnormal situations, one of the most common problems is abnormal power failure. Abnormal power failure may cause data corruption in the system memory, which in turn causes problems such as the inability to start the vehicle terminal's operating system or loss of user data, seriously affecting the normal operation of the vehicle and user experience.

[0046] Figure 1 is a schematic structural diagram of a vehicle-mounted terminal provided by an embodiment of the present invention, Figure 2 is a flow chart of a method for starting a vehicle terminal provided by an embodiment of the present invention, such as Figure 1 As shown, the vehicle terminal 1 includes a system memory 11 and a logic memory 12. Figure 2 As shown, the startup method includes:

[0047] S100: The vehicle terminal is powered on to determine whether the data in the system memory is damaged.

[0048] Specifically, Figure 1 As shown, the vehicle terminal 1 may include a mainboard and a logic memory 12, and the mainboard and the logic memory 12 are connected via a serial peripheral interface (Serial Peripheral Interface, SPI). A processor and a system memory 11 are provided on the mainboard, that is, the system memory 11 and the logic memory 12 are connected via SPI. The logic memory 12 has data identical to the data in the system memory 11 backed up internally. During the startup of the operating system of the vehicle terminal 1, the vehicle terminal 1 is first powered on, and the processor determines whether the data in the system memory 11 is damaged. The data in the system memory 11 may include system data and user data. If the processor determines that the data in the system memory 11 is damaged, S111 is executed.

[0049] S111: Starting the operating system of the vehicle terminal through the data backed up in the logical memory.

[0050] Specifically, Figure 1As shown, after the processor determines that the data in the system memory 11 is damaged, the processor can mount the logic memory 12 in read-only mode, and start the operating system of the vehicle terminal 1 through the data backed up in the logic memory 12 that is the same as the data in the system memory 11, that is, load the necessary system files and configuration files from the logic memory 12 to ensure that the operating system of the vehicle terminal 1 can be started normally. It is ensured that the vehicle terminal 1 can be started normally after the data in the system memory 11 is damaged due to abnormal power failure.

[0051] S120: Mount the logical memory in read-only mode, and mount the system memory in read-write mode.

[0052] Specifically, Figure 1 As shown, after the vehicle terminal 1 is normally started, the vehicle terminal 1 enters the recovery process. At this time, the processor mounts the system memory 11 in a read-write mode to ensure that the data can be written normally. The processor continues to mount the logical memory 12 in a read-only mode to avoid the vehicle terminal 1 being powered off again during the recovery process, causing the data in the logical memory 12 to be damaged, thereby causing both the system memory 11 and the logical memory 12 to fail to work properly, and also to avoid the problem of the data restored from the logical memory 12 to the system memory 11 being inconsistent with the backup data due to another power outage, and the problem of incomplete data recovery.

[0053] S130: Perform disk repair on the system memory, and restore the data backed up in the logical memory to the system memory.

[0054] Specifically, Figure 1 As shown, the processor starts to perform disk repair operations on the system memory 11 to check and repair the damaged file system. After the repair is completed, the processor restores the backup data in the logical memory 12 to the system memory 11 to complete the data recovery of the system memory 11. During the recovery process, the system memory 11 remains in a readable and writable state to ensure that data can be written normally.

[0055] The technical solution of the embodiment of the present invention, through the dual memory design of the system memory and the logical memory, can start the operating system of the vehicle terminal from the backup logical memory when the data of the system memory is damaged due to abnormal power failure. After the operating system of the vehicle terminal is normally started, the processor automatically repairs the damaged system memory and recovers the data from the logical memory to ensure that the system resumes normal operation. The processor can complete the data recovery of the system memory through simple mounting switching and data copying operations, which simplifies the data recovery process and improves the recovery efficiency and reliability. At the same time, in the process of recovering data, the logical memory of the operating system of the vehicle terminal can be normally started in a read-only state, avoiding the problem that the backup logical memory data is damaged due to abnormal power failure again during the data recovery process, resulting in the problem that both memories cannot work normally. The technical solution of the embodiment of the present invention, when the vehicle terminal is abnormally powered off, can ensure that the operating system of the vehicle terminal is started from the backup logical memory, and after the startup is completed, the system memory is repaired and the data is recovered, while ensuring the data consistency during the recovery process, effectively improving the reliability and stability of the vehicle terminal, avoiding the problem that the operating system of the vehicle terminal cannot be started abnormally or the user data is lost due to abnormal power failure, and ensuring the safety of the driver and user experience.

[0057] S200: The vehicle terminal is powered on to determine whether the data in the system memory is damaged.

[0058] Specifically, Figure 1 As shown, if the processor determines that the data in the system memory 11 is damaged, S211 is executed; if the processor determines that the data in the system memory 11 is not damaged, S212 is executed.

[0059] S211: Start the operating system of the vehicle terminal through the data backed up in the logical memory.

[0060] S221: Mount the logical storage in read-only mode and mount the system storage in read-write mode.

[0061] S231: Perform disk repair on the system memory and restore the data backed up in the logical memory to the system memory.

[0062] Specifically, Figure 1 As shown, after the data recovery of the system memory 11 is completed, the vehicle terminal 1 can be powered on again through the processor or manual control, so that the vehicle terminal 1 enters a normal startup process.

[0063] S212: Mount the system memory in read-only mode, and mount the logical memory in read-write mode.

[0064] Specifically, Figure 1 As shown, if the processor determines that the data in the system memory 11 is not damaged, the processor mounts the system memory 11 in read-only mode to ensure that the data in the system memory 11 will not be changed, and mounts the logical memory 12 in read-write mode to prepare for data backup.

[0065] S222: Back up the data in the system memory to the logical memory again.

[0066] Specifically, Figure 1 As shown, the processor backs up the key data in the system memory 11, such as system files and configuration files, to the logical memory 12. Each time the vehicle terminal 1 is powered on, the processor determines that the data in the system memory 11 is not damaged, and the processor backs up the key data in the system memory 11 to the logical memory 12 to ensure that the backup data in the logical memory 12 is always consistent with the data in the system memory 11. During the data backup process, the system memory 11 remains in a read-only state to prevent the data in the system memory 11 from being accidentally modified.

[0067] S232: Mount the system memory in a read-write mode and mount the logical memory in a read-only mode.

[0068] Specifically, Figure 1 As shown, after the data backup is completed, in order to configure the user data after subsequent startup, the processor mounts the system memory 11 in a read-write mode to allow normal operation of the system of the vehicle terminal 1. The processor mounts the logic memory 12 in a read-only mode as a backup memory.

[0069] S242: Start the operating system of the vehicle terminal through the data in the system memory.

[0070] Specifically, Figure 1 As shown, the processor loads necessary system files and configuration files from the system memory 11 to ensure that the operating system of the vehicle terminal 1 can operate normally, and the vehicle terminal 1 enters a normal operating state.

[0071] When backing up data in an existing vehicle-mounted terminal, if a power outage occurs again, the data in the main memory and the backup memory may be inconsistent, that is, some data may not be fully backed up, thus affecting the effect of data recovery. The technical solution of the embodiment of the present invention mounts the system memory 11 in read-only mode during data backup, effectively avoiding the problem of inconsistent data backup caused by another power outage during data backup, and further improving the reliability and data security of the vehicle-mounted terminal 1 under abnormal power outages. The technical solution of the embodiment of the present invention makes the memory of the operating system that can normally start the vehicle-mounted terminal 1 in a read-only state during data backup and data recovery, that is, during the data backup process, the system memory 11 is guaranteed to be in a read-only state, and during the data recovery process, the logical memory 12 is guaranteed to be in a read-only state, preventing the two memories from failing to work normally due to another power outage during data backup and data recovery, while ensuring data consistency and integrity during data backup and data recovery, and improving the reliability and stability of the vehicle-mounted terminal 1.

[0074] Specifically, Figure 1 As shown, in the boot phase, the code of the system memory 11 has the starting flash addresses of the boot partition, kernel partition, and rootfs partition by default. The processor finds other startup data on the system memory 11 according to the matching of the device bus, and the processor determines whether the other startup data is damaged. If the processor determines that the other startup data is damaged, S311 is executed, and if the processor determines that the other startup data is not damaged, S312 is executed.

[0075] S311: Start the operating system of the vehicle terminal through the data backed up in the logical memory.

[0076] S321: Mount the logical storage in read-only mode and mount the system storage in read-write mode.

[0083] S400: The vehicle terminal is powered on to determine whether the data in the system memory is damaged.

[0084] Specifically, Figure 1 As shown, if the processor determines that the data in the system memory 11 is damaged, S411 is executed; if the processor determines that the data in the system memory 11 is not damaged, S412 is executed.

[0086] Specifically, Figure 1 As shown, the processor finds other startup data on the system memory 11 according to the matching of the device bus, and the processor determines whether the other startup data is damaged. If the other startup data is damaged, the processor finds the logical memory 12 with data backup according to the matching of the device bus, and mounts the logical memory 12 in read-only mode.

[0087] S421: Start the operating system of the vehicle terminal according to the address of the rootfs partition of the logical memory.

[0095] Figure 6 is a schematic diagram of the structure of a starting device of a vehicle terminal provided by an embodiment of the present invention, such as Figure 6 As shown, the startup device includes: a first startup module 21, used to start the operating system of the vehicle terminal through the data backed up in the logical memory when the data in the system memory is damaged. A mode mounting module 22, used to mount the logical memory in read-only mode and the system memory in read-write mode. A repair module 23, used to perform disk repair on the system memory. A data recovery module 24, used to restore the data backed up in the logical memory to the system memory.

[0096] Specifically, refer to Figure 1 In the process of starting the operating system of the vehicle terminal 1, the vehicle terminal 1 is first powered on. After the data in the system memory 11 is damaged, the mode mounting module 22 can mount the logic memory 12 in read-only mode. The first startup module 21 starts the operating system of the vehicle terminal 1 through the data backed up in the logic memory 12 that is the same as the data in the system memory 11, that is, loads the necessary system files and configuration files from the logic memory 12 to ensure that the operating system of the vehicle terminal 1 can be started normally. It is ensured that the vehicle terminal 1 can be started normally after the data in the system memory 11 is damaged due to abnormal power failure.

[0097] After the vehicle terminal 1 is started normally, the vehicle terminal 1 enters the recovery process. At this time, the mode mounting module 22 mounts the system memory 11 in a read-write mode to ensure that data can be written normally. The mode mounting module 22 continues to mount the logical memory 12 in a read-only mode to avoid the vehicle terminal 1 being powered off again during the recovery process, causing the data in the logical memory 12 to be damaged, thereby causing both the system memory 11 and the logical memory 12 to fail to work properly, and also to avoid the problem of the data restored from the logical memory 12 to the system memory 11 being inconsistent with the backup data and the incomplete data recovery caused by another power outage.

[0098] Finally, the repair module 23 starts to perform disk repair operations on the system memory 11, checks and repairs the damaged file system. After the repair is completed, the data recovery module 24 restores the backup data in the logical memory 12 to the system memory 11, completing the data recovery of the system memory 11. During the recovery process, the system memory 11 remains in a readable and writable state to ensure that data can be written normally.

[0099] The technical solution of the embodiment of the present invention, through the dual memory design of system memory and logical memory, when the system memory data is damaged due to abnormal power failure, the first startup module 21 can start the operating system of the vehicle terminal from the backup logical memory. After the operating system of the vehicle terminal is normally started, the repair module 23 automatically repairs the damaged system memory, and the data recovery module 24 recovers the data from the logical memory to ensure that the system resumes normal operation. The mode mounting module 22 can complete the data recovery of the system memory through simple mounting switching, and the data recovery module 24 can complete the data recovery of the system memory through simple data copying operations, which simplifies the data recovery process and improves the recovery efficiency and reliability. At the same time, in the process of recovering data, the logical memory of the operating system of the vehicle terminal that can be normally started is in a read-only state, avoiding the problem that the backup logical memory data is damaged due to abnormal power failure again during the data recovery process, resulting in the two memories not being able to work normally. The technical solution of the embodiment of the present invention can ensure that the operating system of the vehicle terminal is started from the backup logical memory when the vehicle terminal is abnormally powered off, and perform disk repair and data recovery on the system memory after the startup is completed, while ensuring data consistency during the recovery process, thereby effectively improving the reliability and stability of the vehicle terminal, avoiding the problem of the vehicle terminal's operating system being unable to start up or user data being lost due to abnormal power off, and ensuring the driver's safety and user experience.

[0100] Optionally, based on the above embodiments, continue to refer to Figure 6 The mode mounting module 22 is also used to mount the system memory in a read-only mode and mount the logical memory in a read-write mode.

[0101] Specifically, refer to Figure 1 The mode mounting module 22 can mount the system memory 11 as a read-only mode or a read-write mode, and can also mount the logical memory 12 as a read-only mode or a read-write mode. The mode mounting module 22 can switch the mounting of the system memory 11 and the logical memory 12 arbitrarily.

[0102] Optionally, based on the above embodiments, continue to refer to Figure 6 The startup device further includes: a backup module 25, which is used to back up the data in the system memory to the logic memory. A second startup module 26, which is used to start the operating system of the vehicle terminal through the data in the system memory.

[0103] Specifically, refer to Figure 1When the data in the system memory 11 is not damaged, the mode mounting module 22 mounts the system memory 11 in read-only mode to ensure that the data in the system memory 11 will not be changed. The mode mounting module 22 mounts the logical memory 12 in read-write mode to prepare for data backup.

[0104] The backup module 25 backs up the key data in the system memory 11, such as system files and configuration files, to the logical memory 12. Each time the vehicle terminal 1 is powered on, if the data in the system memory 11 is not damaged, the backup module 25 will back up the key data in the system memory 11 to the logical memory 12 to ensure that the backup data in the logical memory 12 is always consistent with the data in the system memory 11. During the data backup process, the system memory 11 remains in a read-only state to prevent the data in the system memory 11 from being accidentally modified.

[0105] After the data backup is completed, in order to configure the user data after subsequent startup, the mode mounting module 22 mounts the system memory 11 in a read-write mode to allow normal operation of the system of the vehicle terminal 1. The mode mounting module 22 mounts the logic memory 12 in a read-only mode as a backup memory.

[0106] The second startup module 26 loads necessary system files and configuration files from the system memory 11 to ensure that the operating system of the vehicle-mounted terminal 1 can operate normally, and the vehicle-mounted terminal 1 enters a normal working state.

[0107] According to the technical solution of the embodiment of the present invention, during data backup, the mode mounting module 22 mounts the system memory 11 in read-only mode, which effectively avoids the problem of inconsistent data backup caused by power failure during data backup, and further improves the reliability and data security of the vehicle terminal 1 in the case of abnormal power failure. According to the technical solution of the embodiment of the present invention, during data backup and data recovery, the memory of the operating system that can normally start the vehicle terminal 1 is in a read-only state, that is, during data backup, the mode mounting module 22 ensures that the system memory 11 is in a read-only state, and during data recovery, the mode mounting module 22 ensures that the logical memory 12 is in a read-only state, preventing the two memories from being unable to work normally due to power failure during data backup and data recovery, and at the same time ensuring data consistency and integrity during data backup and data recovery, and improving the reliability and stability of the vehicle terminal 1.
