Detailed Description
The technical scheme of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these examples.
The basic idea of the invention is to judge whether the backup files in the external storage device are the same as the configuration files of the application program, if not, the backup files in the external storage device are copied to the program configuration file catalog of the application program for updating; judging whether a function interface of the configuration parameters is called, if yes, judging whether the backup files in the external storage equipment are the same as the configuration files of the application program, if not, copying the configuration files of the application program into the external storage equipment for re-backup, thereby realizing automatic updating and re-backup of the external storage equipment, ensuring the reliability of the configuration files in the running process of the system, reducing the extra configuration workload brought to engineering personnel due to the loss or inconsistency of the configuration files in the running process of the system, avoiding the occurrence of secondary debugging, and improving the overall running safety and reliability of the electric energy collection system.
The invention provides a method for automatically backing up configuration files by using external storage equipment, which is shown in figures 1-2 and comprises the following steps:
s1: and judging whether the backup files in the external storage device are the same as the configuration files of the application program, and if not, copying the backup files in the external storage device to the configuration file catalogue of the application program for updating.
Before judging whether the backup file in the external storage device is the same as the configuration file of the application program, the method further comprises the following steps: and detecting whether the backup file exists in the external storage device, if the backup file does not exist, copying the configuration file of the application program into the external storage device, and if the backup file exists, judging whether the backup file in the external storage device is identical with the configuration file of the application program.
In consideration of the use of the new external storage device, the backup file is not stored in the external storage device, so that when the backup file is judged to be not in the external storage device, the configuration file of the application program is only required to be copied into the external storage device, and comparison with the configuration file of the application program is not required.
In this embodiment, the method for determining whether the backup file in the external storage device is the same as the configuration file of the application program is as follows: and obtaining MD5 codes of the backup files in the external storage device and the configuration files of the application program, comparing the MD5 codes of the backup files in the external storage device with the MD5 codes of the configuration files of the application program, judging that the backup files in the external storage device are identical to the configuration files of the application program if the MD5 codes are identical to the MD5 codes of the configuration files of the application program, and judging that the backup files in the external storage device are different from the configuration files of the application program if the MD5 codes are different from the configuration files of the application program.
MD5 code is a 128-bit hash generated by a widely used cryptographic hash function to ensure that the information transfer is completely consistent. The Linux system has a special command MD5sum to calculate the MD5 code of each file, and the MD5 codes generated by different file contents are different.
S2: judging whether a function interface call of the configuration parameters exists, if so, judging whether the backup file in the external storage device is the same as the configuration file of the application program, and if not, copying the configuration file of the application program into the external storage device for re-backup.
In this embodiment, the method for judging whether there is a function interface call of the configuration parameter is: the application program creates a shared message queue, the end of the function of the configuration parameter sends a message to the shared message queue of the application program, and an independent monitoring thread in the application program always monitors the message queue, and the function interface with the configuration parameter is called as long as the message exists.
If so, the configuration file of the application program is possibly updated, so that the backup file in the external storage device needs to be backed up.
The use of the new external storage device is considered, and the backup file is not stored in the external storage device, so that when the backup file is judged to be not in the external storage device, the configuration file of the application program is only required to be copied into the external storage device, and comparison with the configuration file of the application program is not required.
When the backup files are in the external storage device, judging whether the backup files in the external storage device are the same as the configuration files of the application program, and if not, copying the configuration files of the application program into the external storage device for re-backup. In step S2, the method of judging whether the backup file in the external storage device is the same as the configuration file of the application program also adopts the MD5 code comparison method in step S1.
Step S1 realizes automatic update of the configuration file of the application program, and step S2 realizes automatic backup of the external storage device. The external storage device can automatically backup the latest configuration file only if configuration parameters are changed, and when the device fails, the external storage device is pulled out and reinserted on a new main board, and the backup file in the external storage device can be automatically updated to the application program configuration file catalog again after the new main board starts the system. Therefore, the reliability of the configuration file in the running process of the system is ensured, the extra configuration workload is brought to engineering personnel because the configuration file is lost or inconsistent in the running and maintenance process of the system is reduced, the occurrence of secondary debugging is avoided, and the overall running safety and reliability of the electric energy collection system are improved.
In this embodiment, the external storage device may be a TF card, an SD card, or other storage devices. Taking a TF card as an example, the TF card can be automatically identified only by customizing a related driver under a Linux system, the device file name of the TF card can be seen under a file system device directory, the partition table information can be checked by using a partition table checking command fdisk with parameters (-l), then a backup file directory is created in the file system by using an mkdir command, and a mount command is added in a system starting script to mount the TF card to the backup file directory, so that the TF card can be automatically mounted to the backup file directory every time the system is started.
The hardware platform supporting the expansion of the TF card, such as an ARM-Cortex-A9 processor chip, can be compatible with other Cortex series processor technologies, provides a solution with high expansibility, and custom installs a Linux operating system capable of automatically identifying the TF card; 2) Checking TF card equipment files by using commands under a Linux system, creating a catalog of backup configuration files in a file system, and adding commands to mount TF cards to the catalog of the configuration files in a system starting file; 3) Writing two SHELL command scripts, wherein the first function is to automatically update the configuration file from the TF card, the second function is to automatically backup the configuration file to the TF card, the MD5 code detection of the configuration file and the backup file is realized in the script, and the update or backup of the configuration file is judged according to the difference of the MD5 codes; 4) After the system is started, a first script is automatically executed, and whether the configuration file of the system needs to be updated is judged; 5) After the application program runs, the operation interface function of the configuration file is monitored, and the second script is executed when the action of the external operation configuration file is encountered, so that the automatic backup of the configuration file can be realized.
It should be noted that, other types of storage devices also implement automatic backup and update of the configuration file by the method, which is not described in this embodiment.
Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
