Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes an embodiment of the vehicle-mounted intelligent terminal in detail based on the upgrading method of the vehicle-mounted intelligent terminal. As shown in fig. 1, which is a schematic flow chart of an upgrading method for a vehicle-mounted intelligent terminal according to an embodiment of the present invention, a specific implementation process includes the following steps:
step 101: and under the condition that the vehicle-mounted intelligent terminal enters a preset mode and receives an upgrade recovery instruction, creating a mounting point.
In a specific embodiment, in the system recovery mode, the vehicle-mounted intelligent terminal generally has no function of identifying the external storage device. In the embodiment of the invention, when the vehicle-mounted intelligent terminal enters the recovery mode, a user accesses the storage equipment containing the target upgrade file, and when an automatic recovery upgrade instruction is triggered by clicking, a corresponding self-mounted point can be established for the external storage equipment.
In one embodiment, the mount point refers to a specific file directory. The creating of the corresponding mount point is to create a mounted device file directory at the vehicle-mounted intelligent terminal, and place the external storage device in the device file directory, for example, create mkdir/mnt/USB (Universal Serial Bus) for the USB external storage device.
Step 102: and determining the equipment node corresponding to the external storage equipment in the vehicle-mounted intelligent terminal.
Specifically, a storage medium device node file directory, such as/dev/block/, of the vehicle-mounted intelligent terminal system is determined, all device nodes in the storage medium device node file directory are automatically searched, if device nodes corresponding to the external storage device in the storage medium device node file directory are searched, the existing device nodes are tried to be mounted to a mounting point of the device nodes one by one, namely, a mapping relation between the searched device nodes and the mounting point is established, and the device nodes are mounted to the mounting point.
In one embodiment, the mounting is a process of placing a partition or disk in a device file directory, specifically, a process of making a computer file and a device file directory on a storage device (such as a hard disk, a CD-ROM, or a shared resource) accessible to a user through a file system of a computer by an operating system. The device node may refer to a storage device file node.
Step 103: and accessing the equipment node through the mounting point, and upgrading the vehicle-mounted intelligent terminal based on a target upgrading file existing in the equipment node.
And after the mounting is successful, searching the mounting point path, searching whether a target upgrading file exists in the equipment node, and if the target upgrading file exists, directly using the target upgrading file to carry out system upgrading recovery from the external storage equipment.
In a specific embodiment, it is required to first obtain name feature information corresponding to the target upgrade file, search the target upgrade file corresponding to the name feature information in the device node with the name feature information as an index, set an absolute path corresponding to the target upgrade file as an upgrade path if the target upgrade file is found, and perform system upgrade processing from the external storage device based on the upgrade path.
In a specific implementation process, if the target upgrade file is not found, the current device node mounted on the mounting point is unloaded, device nodes corresponding to subsequent external storage devices are continuously mounted, the device nodes corresponding to the subsequent external storage devices are sequentially traversed, and whether the target upgrade file exists in other device nodes is judged. The target upgrading file is a preset system or software installation package with a specific format.
For the currently used vehicle-mounted intelligent terminal, because a touch screen is usually adopted, all operation instructions are realized by clicking the touch screen, and the executable operations that a user can see on the vehicle-mounted intelligent terminal when the current system is in the recovery mode include: automatic upgrade recovery or restart. If a fault is met, the user can restart the computer by lightly touching the computer; the method for upgrading the vehicle-mounted intelligent terminal can be executed by triggering automatic upgrading recovery through long pressing, and system restarting recovery can be realized.
And when detecting that the user automatically restores the upgrading instruction, inserting an external storage device, and searching a target upgrading file by traversing all possible mounting points by the vehicle-mounted intelligent terminal. And if the target upgrade file exists, setting the absolute path as an upgrade path, and directly performing system upgrade recovery from the external storage device. In the actual implementation process, since the system itself does not know which mount point in the storage device, at which mount point the upgrade file can be accessed, all mount points need to be traversed, and sequentially mount to the created mount points through traversing the path in the system, and search one by one, if a target upgrade file is found in the device node, the search is exited, and the system is directly upgraded by using the absolute path of the found upgrade file (update.
As shown in fig. 2, in an actual implementation, after the system failure enters the recovery mode, it may be determined whether all device nodes mounted to the mounting point have been traversed first; if not, mounting the next equipment node, and further judging whether the equipment node has an upgrade file; if yes, setting a corresponding upgrading path to realize system restarting upgrading; and if not, unloading the equipment node corresponding to the current mounting point.
By adopting the upgrading method of the vehicle-mounted intelligent terminal provided by the embodiment of the invention, the external storage equipment can be automatically mounted to search for the corresponding upgrading file under the condition of entering the preset mode and receiving the upgrading recovery instruction, the upgrading can be directly carried out from the external storage equipment, a user does not need to manually search for the internal storage file, the operation is simple, the vehicle-mounted intelligent terminal can be quickly recovered to be normal after the vehicle-mounted equipment terminal breaks down in the hand of the user, the time and the economic cost for the user to return to after-sale maintenance are reduced, and the use experience of the user is greatly improved.
