Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
[ first embodiment ]
As shown in fig. 1, a method for backing up parameters provided in a first embodiment of the present invention includes the steps of:
s11: generating a backup control instruction according to a target backup mode;
s13: acquiring identification information and configuration parameters of a display controller and configuration parameters of a target receiving card connected with the display controller according to the backup control instruction;
s15: generating a backup file according to the identification information and the configuration parameters of the display controller and the configuration parameters of the target receiving card; and
s17: and storing the backup file into a backup area corresponding to the target backup mode.
In view of the foregoing, in this embodiment, all the configuration parameters obtained are stored in a file manner, and the backup file has special identification information for characterizing the type of the display controller supported by the backup file and some basic information of the backup parameters, for example, the basic information is placed at the file header of the backup file. The data in the backup file is organized in a specific format, the backup file is generated or analyzed according to the format, and the expansibility and the compatibility are considered, so that the subsequent backup file is conveniently updated. The backup file is a parameter set of system operation, and absolute reliability and accuracy are required, so that verification information can be added into the backup file to verify the integrity and accuracy of the backup file during parameter restoration.
In this embodiment, because a unified file format is adopted, the backup files can be transferred in different storage media without difference. For example, the backup files can be transmitted between the display controllers and the computer in a file mode, and can also be transmitted from the display controllers to the USB flash disk through the USB interface, so that the USB flash disk can be used for copying and transmitting the backup files among the display controllers under the condition that a plurality of display controllers need to share one configuration file, and the application flexibility is greatly improved. In addition, it should be noted that the configuration parameters are used to control the real-time operation state of the system, and may be read or written to obtain the operation state of the system or change the operation state of the system.
In addition, in order to make the field use convenient for the greatest program, for example, as shown in fig. 2, the embodiment supports three backup modes, that is: backup to local, [ backup to USB flash disk ], and [ backup to computer ]. After the user selects one of the three backup modes, the display controller can generate a backup control instruction according to the backup mode selected by the user.
The "backup to the local" refers to that the acquired configuration parameters (including the configuration parameters of the local display controller and the configuration parameters of the receiving card connected to the display controller) can be stored by using a high-capacity nonvolatile memory of the local display controller, such as a Flash chip.
The backup to the USB disk refers to that an external memory access interface of the display controller, for example, a USB interface, may be used to connect to a mobile storage device, for example, a USB disk, so as to backup the acquired configuration parameters to the mobile storage device connected to the display controller.
The "backup to computer" refers to that the acquired configuration parameters can be uploaded to the computer by using a communication interface (such as a serial port, a USB port or a network port) of the display controller, and the operation needs to be performed by a software platform provided by the system.
In addition, it is worth mentioning that, for the backup area described in step S15, it is a storage area on the display controller when the selected target backup mode is [ backup to local ], it is a storage area on the mobile storage device externally connected to the display controller when the selected target backup mode is [ backup to U disk ], and it is a storage area on the computer connected to the display controller when the selected target backup mode is [ backup to computer ].
In addition, as can be seen from the above, for the complicated and changeable configuration of the parameters of the receiving card, the embodiment can also realize backup, for example, the configuration parameters of the first receiving card under the first network port with the link of the backup display controller. The display controller communicates with the receiving card through a predetermined protocol, and each parameter has a unique corresponding custom address space, so that the display controller can read back the data in the address space, generate file information according to a specific format, and send and store the file information in the backup area. In addition, it is worth mentioning that, because the LED display screen system mainly comprises LCT software (screen matching software), a display controller and a receiving card, the display controller also stores some information of the LCT software, and the operation is required to be performed during backup and restoration, so that the working state acquired by the software is consistent with the working state of the current display controller, and the whole system is ensured to be complete and effective.
[ second embodiment ]
As shown in fig. 3, a parameter backup apparatus 30 according to a second embodiment of the present invention includes: an instruction generation module 31, an information acquisition module 33, a file generation module 35, and a file storage module 37.
The instruction generating module 31 is configured to generate a backup control instruction according to a target backup mode, for example; the information obtaining module 33 is configured to obtain, for example, identification information and configuration parameters of a display controller and configuration parameters of a target receiving card connected to the display controller according to the backup control instruction; the file generating module 35 is configured to generate a backup file according to a preset format, for example, by using the identification information and the configuration parameters of the display controller and the configuration parameters of the target receiving card; the file storage module 37 is, for example, configured to store the backup file in a backup area corresponding to the target backup mode.
As for the specific functional details of the instruction generating module 31, the information acquiring module 33, the file generating module 35 and the file storing module 37, reference is made to the detailed description in the foregoing first embodiment, and the details are not repeated here. Further, it is worth mentioning that the instruction generating module 31, the information acquiring module 33, the file generating module 35 and the file storing module 37 may be software modules, stored in a nonvolatile memory and executed by a processor to perform the steps S11, S13, S15 and S17 in the foregoing first embodiment.
[ third embodiment ]
As shown in fig. 4, a parameter restoring method provided in a third embodiment of the present invention includes the steps of:
s41: generating a reduction control instruction according to the target reduction mode and the selected equipment to be reduced;
s43: reading backup files in a preset format from a backup area corresponding to the target restoring mode according to the restoring control instruction;
s45: analyzing the identification information of the display controller contained in the backup file to judge whether the identification information is matched with the current display controller; and
s47: and after the judgment result is that the backup file is matched, analyzing the target parameters in the backup file, and sending the target parameters to the equipment to be restored so as to restore the parameters of the equipment to be restored.
The target reduction mode is selected from one of a plurality of reduction modes, for example, and the plurality of reduction modes include, for example: restoring from the display controller, restoring from a storage device externally connected to the display controller, and restoring from a computer connected to the display controller; the selected equipment to be restored is as follows: and selecting the current display controller as equipment to be restored or selecting a receiving card connected with the current display controller as equipment to be restored.
In order to make the present embodiment most convenient for field use, for example, as shown in fig. 5, three reduction modes are supported, namely: reduction from local, [ reduction from U disk ], and [ reduction from computer ]. After the user selects one of the three backup modes, the sub items [ controller restore ] and [ receiver card restore ] can be further displayed to determine the device to be restored, and then the display controller can generate a restore control instruction according to the restore mode selected by the user and the device to be restored (such as a controller or a receiver card).
The "restore from local" refers to reading backup files in a preset format from a high-capacity nonvolatile memory, such as a Flash chip, of the display controller, and analyzing the backup files to restore parameters of the device to be restored.
The step of recovering from the USB flash disk refers to reading backup files with a preset format from external mobile storage equipment such as the USB flash disk by using an external memory access interface, such as a USB interface, of the display controller, and analyzing the backup files to realize parameter recovery of the equipment to be recovered.
The term "restore from computer" refers to reading backup files in a preset format from a computer connected to a display controller by using a communication interface (such as a serial port, a USB port or a network port) of the display controller, and analyzing the backup files to restore parameters of the device to be restored.
For the system, the current working state is mainly controlled by parameters of the working area, the backup area and the working area can interact through a backup control instruction and a restoration control instruction, and the control instruction can be sent by a man-machine interaction interface of the display controller, so that the display controller works in a specific mode. The backup control instruction can copy the configuration parameters of the working area to the backup area, and the restoration control instruction can copy the configuration parameters of the backup area to the working area of the equipment to be restored, so that parameter restoration is realized.
Therefore, in this embodiment, the term "controller restore" refers to copying and applying the configuration parameters of the display controller in the parsed backup file to the working area of the display controller, so as to implement the restoration of the configuration parameters of the display controller system; the term "receiving card restore" refers to copying and applying the configuration parameters of the receiving card in the parsed backup file to the working area of the receiving card, so as to restore the configuration parameters of the receiving card system.
For example, when parameter restoration is performed on a plurality of receiving cards in the LED display screen system, the display controller sends the parsed receiving card configuration parameters to all receiving cards under all network ports linked by the display controller in a broadcast manner, so that the working area of each receiving card is switched to the working state of the restoration point.

As shown in fig. 6, a parameter restoring apparatus 60 according to a fourth embodiment of the present invention includes: an instruction generation module 61, a file reading module 63, a file parsing module 65 and a parameter parsing transmission module 67.

For the specific functional details of the instruction generating module 61, the file reading module 63, the file parsing module 65 and the parameter parsing sending module 67, reference is made to the detailed description in the foregoing third embodiment, and the details are not repeated here. Furthermore, it should be noted that the instruction generating module 61, the file reading module 63, the file parsing module 65 and the parameter parsing sending module 67 may be software modules, stored in a nonvolatile memory and executed by a processor to perform the steps S41, S43, S45 and S47 in the foregoing third embodiment.
