Detailed Description
The technical solutions of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
The basic idea of the invention is to judge whether the backup file in the external storage device is the same as the configuration file of the application program, if not, the backup file in the external storage device is copied to the program configuration file directory of the application program for updating; judging whether a function interface of the configuration parameters is called, if so, judging whether a backup file in the external storage equipment is the same as the configuration file of the application program, if not, copying the configuration file of the application program into the external storage equipment for backuping, thereby realizing automatic updating and backuping of the external storage equipment, ensuring the reliability of the configuration file in the operation process of the system, reducing extra configuration workload brought to engineering personnel because the configuration file is lost or inconsistent in the operation and maintenance process of the system, avoiding the occurrence of secondary debugging and improving the safety and reliability of the whole operation of the electric energy acquisition system.
The invention provides a method for automatically backing up configuration files by using an external storage device, which comprises the following steps as shown in figures 1-2:
s1: and 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 backup file in the external storage device to a configuration file directory 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: detecting whether a backup file exists in the external storage equipment, copying the configuration file of the application program into the external storage equipment if the backup file does not exist, and judging whether the backup file in the external storage equipment is the same as the configuration file of the application program if the backup file exists.
In consideration of the use of a new external storage device, the internal part of the external storage device does not store backup files, so that when the external storage device is judged to have no backup files, only the configuration files of the application program need to be copied into the external storage device, and the comparison with the configuration files of the application program is not needed.
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 includes: and obtaining MD5 codes of the backup files in the external storage device and the configuration files of the application programs, comparing the MD5 codes of the backup files in the external storage device with the MD5 codes of the configuration files of the application programs, if the MD5 codes of the backup files in the external storage device and the MD5 codes of the configuration files of the application programs are the same, judging that the backup files in the external storage device are the same as the configuration files of the application programs, and if the MD5 codes of the backup files in the external storage device and the MD5 codes of the configuration files of the application programs are different.
The MD5 code is a 128-bit hash value generated by a widely used cryptographic hash function to ensure the integrity of the information transmission. In the Linux system, a unique command MD5sum is used for calculating the MD5 code of each file, and the MD5 code generated by different file contents is different.
S2: and judging whether a function interface of the configuration parameters is called, if so, judging whether the backup file in the external storage equipment 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 equipment for backuping.
In this embodiment, the method for determining whether there is a function interface call for configuring parameters includes: the application program can create 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, an independent monitoring thread in the application program can monitor the message queue all the time, and the function interface with the configuration parameter is judged to be called as long as the message exists.
If yes, the configuration file of the application program is possible to be updated, so that the backup file in the external storage device needs to be backed up.
In the same way, the use of a new external storage device is considered, and no backup file is stored in the external storage device, so that when the external storage device is judged to have no backup file, only the configuration file of the application program needs to be copied into the external storage device, and the comparison with the configuration file of the application program is not needed.
And when the external storage equipment has the backup file, judging whether the backup file in the external storage equipment 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 equipment for backuping. The method for determining whether the backup file in the external storage device is the same as the configuration file of the application program in step S2 is the same as the MD5 code comparison method in step S1.
Step S1 enables automatic update of the configuration file of the application program, and step S2 enables automatic backup of the external storage device. The external storage device can automatically back up the latest configuration file as long as the configuration parameters are changed, and when the device fails, the external storage device is pulled out and is plugged into a new mainboard again, and the new mainboard can automatically update the backup file in the external storage device to the application program configuration file directory again after the system is started. Therefore, the reliability of the configuration files in the operation process of the system is ensured, extra configuration workload is brought to engineering personnel due to the loss or inconsistency of the configuration files in the operation and maintenance process of the system, the occurrence of secondary debugging is avoided, and the overall operation safety and reliability of the electric energy acquisition system are improved.
In this embodiment, the external storage device may adopt a TF card or an SD card or other storage devices. Taking a TF card as an example, only a relevant drive is customized in a Linux system, the TF card can be automatically identified, the device file name of the TF card can be seen in a file system device directory, a partition table viewing command fdisk with a parameter (-l) can be used for viewing partition table information, then a backup file directory is created in the file system by an mkdir command, a mount command is added in a system startup script to mount the TF card to the backup file directory, and thus the TF card can be automatically mounted to the backup file directory every time the system is started.
The hardware platform supporting TF card expansion, such as an ARM-Cortex-A9 processor chip, can be compatible with other Cortex series processor technologies, and provides a high-expansibility solution, and a Linux operating system capable of automatically identifying TF cards is customized and installed; 2) checking a TF card equipment file by using a command under a Linux system, creating a directory of a backup configuration file in a file system, and adding the command to mount the TF card to the directory of the configuration file in a system starting file; 3) writing two SHELL command scripts, wherein the first function is to automatically update the configuration files from the TF card, the second function is to automatically backup the configuration files into the TF card, MD5 code detection of the configuration files and the backup files is realized in the scripts, and the configuration files are judged to be updated or backed up according to different MD5 codes; 4) after the system is started, the first script is automatically executed, and whether the configuration file of the system needs to be updated or not is judged; 5) after the application program runs, the configuration file operation interface function is monitored, and when the action of operating the configuration file from the outside is met, the second script is executed, 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 configuration files by the method, which is not described in this embodiment.
Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
