and S100, powering on the vehicle-mounted terminal, and judging whether the data of the system memory are damaged.
Specifically, as shown in fig. 1, the in-vehicle terminal 1 may include a motherboard and a logic memory 12, where the motherboard and the logic memory 12 are connected through a serial peripheral interface (SERIAL PERIPHERAL INTERFACE, SPI). The main board is provided with a processor and a system memory 11, i.e. the system memory 11 is connected with a logic memory 12 through an SPI. The logic memory 12 is internally backed up with the same data as the data inside the system memory 11. In the starting process of the operating system of the vehicle-mounted terminal 1, the vehicle-mounted terminal 1 is powered on first, and the processor judges whether the data of the system memory 11 is damaged, wherein the data of the system memory 11 can comprise system data and user data. If the processor determines that the data of the system memory 11 is corrupted, S111 is performed.

At this time, the processor mounts the system memory 11 in a readable and writable mode, so as to ensure that data can be written normally. The processor continues to mount the logic memory 12 in the read-only mode, so that the problem that the data of the logic memory 12 is damaged due to the fact that the vehicle-mounted terminal 1 is powered off again in the recovery process, the system memory 11 and the logic memory 12 cannot work normally, and the problems that the data of the logic memory 12 recovered to the system memory 11 is inconsistent with the backup data and the data recovery is incomplete due to the fact that the logic memory 12 is powered off again are avoided.

Specifically, as shown in FIG. 1, the processor begins a disk repair operation on the system memory 11, checking for and repairing a corrupted file system. After the repair is completed, the processor restores the backup data in the logical memory 12 to the system memory 11, and completes the data restoration to the system memory 11. During the recovery process, the system memory 11 maintains a readable and writable state, ensuring that data can be written normally.
According to the technical scheme, through the double-memory design of the system memory and the logic memory, when the system memory data is damaged due to abnormal power failure, the operating system of the vehicle-mounted terminal can be started from the backup logic memory. After the operating system of the vehicle-mounted terminal is normally started, the processor automatically repairs the damaged system memory, and recovers data from the logic memory to ensure that the system is recovered to normal operation. The processor can complete data recovery of the system memory through simple mounting switching and data copying operation, so that the data recovery flow is simplified, and the recovery efficiency and reliability are improved. Meanwhile, in the process of recovering data, the logic memory of the operating system of the vehicle-mounted terminal can be normally started to be in a read-only state, so that the problem that the two memories cannot work normally due to data damage of the standby logic memory caused by abnormal power failure again in the process of recovering data is avoided. According to the technical scheme, when the vehicle-mounted terminal is abnormally powered off, the operating system of the vehicle-mounted terminal can be started from the standby logic memory, the disk repair and data recovery are carried out on the system memory after the starting is completed, meanwhile, the data consistency in the recovery process is guaranteed, the reliability and stability of the vehicle-mounted terminal are effectively improved, the problem that the operating system of the vehicle-mounted terminal cannot be started abnormally or user data are lost due to abnormal power off is avoided, and the safety and user experience of a driver are guaranteed.

S212, mounting the system memory into a read-only mode and mounting the logic memory into a readable and writable mode.
Specifically, as shown in fig. 1, if the processor determines that the data in the system memory 11 is not damaged, the processor mounts the system memory 11 in a read-only mode, so as to ensure that the data in the system memory 11 cannot be changed, and mounts the logic memory 12 in a readable and writable mode, so as to prepare for data backup.
S222, backing up the data of the system memory to the logic memory again.
Specifically, as shown in fig. 1, the processor backs up critical data in the system memory 11, such as system files and configuration files, into the logic memory 12. After the vehicle-mounted terminal 1 is powered on each time, the processor judges that the data of the system memory 11 are not damaged, and the processor needs to re-backup the key data in the system memory 11 into the logic memory 12, so that the backup data in the logic memory 12 are always consistent with the data of the system memory 11.

Specifically, as shown in fig. 1, the processor loads necessary system files and configuration files from the system memory 11, so as to ensure that the operating system of the vehicle-mounted terminal 1 can normally operate, and the vehicle-mounted terminal 1 enters a normal working state.
When the existing vehicle-mounted terminal backs up data, if power failure occurs again, data of the main memory and data of the standby memory are possibly inconsistent, namely partial data can be possibly not completely backed up, and therefore the effect of data recovery is affected. In the technical scheme of the embodiment of the invention, the system memory 11 is mounted in a read-only mode during data backup, so that the problem of inconsistent data backup caused by power failure again during data backup is effectively avoided, and the reliability and the data safety of the vehicle-mounted terminal 1 under the abnormal power failure condition are further improved. According to the technical scheme provided by the embodiment of the invention, the memory of the operating system capable of normally starting the vehicle-mounted terminal 1 is in a read-only state in the data backup and data recovery processes, namely, the system memory 11 is ensured to be in the read-only state in the data backup process, the logic memory 12 is ensured to be in the read-only state in the data recovery process, the situation that the two memories cannot normally work due to the fact that the power is cut off again in the data backup and data recovery processes is prevented, meanwhile, the data consistency and the data integrity in the data backup and data recovery processes are ensured, and the reliability and the stability of the vehicle-mounted terminal 1 are improved.

Specifically, referring to fig. 1, when the data of the system memory 11 is not damaged, the mode mounting module 22 mounts the system memory 11 in a read-only mode, so as to ensure that the data of the system memory 11 cannot be changed, and the mode mounting module 22 mounts the logic memory 12 in a read-write mode, so as to prepare for data backup.
The backup module 25 backs up critical data in the system memory 11, such as system files and configuration files, etc., to the logical memory 12. After the vehicle-mounted terminal 1 is powered on each time, the data of the system memory 11 are not damaged, and the backup module 25 needs to re-backup the key data in the system memory 11 into the logic memory 12, so that the backup data in the logic memory 12 is always consistent with the data of the system memory 11. During the data backup process, the system memory 11 maintains a read-only state, preventing the data of the system memory 11 from being modified accidentally.
After the data backup is completed, the mode mounting module 22 mounts the system memory 11 in a readable and writable mode for the user data after the subsequent startup, allowing the normal operation of the system of the in-vehicle terminal 1. The mode mount module 22 mounts the logic memory 12 in read-only mode as a spare memory.
The second starting module 26 loads necessary system files and configuration files from the system memory 11, so as to ensure that the operating system of the vehicle-mounted terminal 1 can normally operate, and the vehicle-mounted terminal 1 enters a normal working state.
According to the technical scheme provided by the embodiment of the invention, the mode mounting module 22 mounts the system memory 11 into the read-only mode during data backup, so that the problem of inconsistent data backup caused by power failure again during data backup is effectively avoided, and the reliability and the data safety of the vehicle-mounted terminal 1 under the abnormal power failure condition are further improved. According to the technical scheme provided by the embodiment of the invention, in the data backup and data recovery processes, the memory of the operating system of the vehicle-mounted terminal 1 can be normally started to be in a read-only state, namely, in the data backup process, the mode mounting module 22 ensures that the system memory 11 is in a read-only state, in the data recovery process, the mode mounting module 22 ensures that the logic memory 12 is in a read-only state, so that the two memories cannot normally work due to the fact that the power is cut off again in the data backup and data recovery processes are prevented, meanwhile, the data consistency and integrity in the data backup and data recovery processes are ensured, and the reliability and stability of the vehicle-mounted terminal 1 are improved.
The vehicle-mounted terminal comprises, but is not limited to, a vehicle-mounted terminal of a mining rubber-tyred vehicle, wherein the vehicle-mounted terminal is started by adopting the starting method of any vehicle-mounted terminal provided by any embodiment of the invention, namely, the vehicle-mounted terminal of the mining rubber-tyred vehicle can be started by adopting the starting method of any vehicle-mounted terminal provided by any embodiment of the invention, and the vehicle-mounted terminal provided by the embodiment of the invention has the beneficial effects of the starting method of any vehicle-mounted terminal provided by any embodiment of the invention.
