In some embodiments, the display devices 20 may be display devices with display screens, with each display device 20 corresponding to a configuration file. The configuration file (also called hardware configuration file) at least comprises an FPGA model, a chip signal, a lamp panel diagram, a lamp panel parameter, a chip register parameter and a display parameter table, namely a Gamma table. Therefore, the same type of display device generally corresponds to the same profile. Wherein:
the server 10 comprises a transceiving component 11, a compiling component 12 and an authentication component 13;
the transceiver component 11 is in communication connection with a display device 20, and is configured to receive user identification information and a configuration file sent by the display device 20;
the authentication component 13 is connected to the transceiving component 11 and the compiling component 12, and is configured to match the user identification information with preset customized identification information, determine target customized identification information, and obtain a firmware source program file corresponding to the target customized identification information;
the compiling component 12 is connected to the transceiving component 11, and is configured to compile the configuration file sent by the transceiving component and the firmware source program file obtained by the authentication component 13, and automatically generate a customized firmware file; the customized firmware file can be downloaded and updated by a display device into an FPGA of a receiving card communicatively connected with the display device.
It should be noted that the firmware files stored in the server are divided into general firmware files and customized firmware files, and the general firmware files are used for standard program loading and are identified and determined by the general identification information. Whereas the customized firmware file cannot generate the generic firmware file in reverse. The customized firmware file is used for loading the customized program and is determined by specific customized identification information, wherein the standard program can be upgraded into the customized program, and the customized program cannot be reversely recast into the standard program.
In this embodiment, compared with the conventional method, the authentication component and the compiling component are added to the server to authenticate and identify the user identification information input by the user, and the user identification information is selectively compiled, so that different upgrades are performed by selecting the firmware file corresponding to the user identification information in a matching manner, and the update of the standard firmware file can be performed only when the authorization verification is passed, thereby ensuring the data security. The authentication component matches the user identification information received by the transceiving component with preset customized identification information, determines target customized identification information, and acquires a firmware source program file corresponding to the target customized identification information, and the compiling component compiles the configuration file sent by the transceiving component and the firmware source program file acquired by the authentication component to automatically generate a customized firmware file, so that a customer can package and deliver the customized firmware file after completing upgrading the customized firmware file on a screen body after downloading the customized firmware file online without subsequently adjusting the customized firmware file.

The problem that the function is not adaptive after upgrading and the application is not available due to the fact that the traditional scheme cannot identify whether the firmware file is the correct customized firmware file of the receiving card through software upgrading, only can light the screen body to check whether the user customized firmware file of the receiving card is correct after upgrading is successful and then the user customized firmware file of the receiving card is on the client site can be solved.
Preferably, the connection between the server 10 and the display device 20 may be implemented by a wired network, a wireless network, or a mobile communication network, and the transceiver component 11 of the server 10 may receive the user ID and the configuration file transmitted by the display device 20 by any of the above connection methods, or may download the compiled customized firmware file to the display device 20 according to a download request of the display device 20 by any of the above connection methods. Similarly, the general firmware file corresponding to the user identification information directly stored in the server 10 may be downloaded to the display device 20 according to a download request of the display device 20 by any of the above connection methods.
Preferably, the user identification information includes a user ID, and the customized identification information includes a customized ID, wherein the customized ID is used to uniquely identify the display device 20, that is, the display device 20 can be uniquely determined by the customized ID.
In this embodiment of the application, the user identification information is used to distinguish whether the FPGA firmware file version of the product is a standard (factory) version firmware file or a customized version firmware file, where the standard version firmware file may be upgraded into the customized version firmware file, but the customized version firmware file cannot be retroactively compiled into the standard version firmware file.
The configuration file comprises the following contents: the FPGA model, the lamp panel diagram, the lamp panel parameters, the chip register parameters, and the display parameter table, i.e., the Gamma table, are not limited. As long as the acquired configuration file can satisfy the configuration file required for the upgrade of the display apparatus.
The configuration file is a configuration file formed of user configuration information that passes a screen body verification test in the display device 20, by which the screen body can normally operate in the case where the firmware files are matched.
In one embodiment, as shown in fig. 2, the authentication component 13 comprises an authentication unit 131 and an acquisition unit 132.
The identification unit 131 is configured to obtain a preset customized identification information base, match the received user identification information with each piece of customized identification information in the customized identification information base, and determine target customized identification information according to a matching result.
The identifying unit 131 is specifically configured to include:
judging whether the received user identification information is the same as the customized identification information;
if the customized identification information is the same as the user identification information, determining that the display device adopts a customized firmware file mode to perform upgrading configuration, and issuing an instruction for generating a customized firmware file to the compiling component, wherein the customized identification information is used as target customized identification information;
if all the customized identification information is different from the user identification information, continuously judging whether the user identification information is general identification information;
if the user identification information is general identification information, determining that the display device adopts a general firmware file mode to carry out upgrading configuration;
and if the user identification information is not the general identification information, the user identification information is illegal information, and error prompt is carried out.
That is, verifying whether the user identification information is preset customized identification information; that is, whether the two are the same or not is judged, if not, the user identification information is not verified to be passed, which indicates that the user identification information is not the preset customized identification information, which indicates that the display device 20 cannot be upgraded by using the customized firmware file and cannot load the customized program; if the user identification information is verified to be passed, the user identification information is the preset customized identification information, the display device 20 may perform upgrade configuration by using the customized firmware file, and at this time, the customized identification information matched with the user identification information is used as the target customized identification information.
It should be noted that the authentication unit 131 in the above embodiment adopts two judgment operations to further ensure data security.
In another embodiment, the difference between the authentication unit 131 and the above embodiments is that only one judgment operation is used to improve data security, that is, when the authentication unit 131 judges that the received user identification information is not the same as all the customized identification information, the judgment of the general identification information is not performed, and it is directly determined that the display device 20 is configured in the general firmware upgrade manner, and therefore, no compiling process is required, and no FPGA process in the receiving card is required to be updated, which simplifies the operation and improves the processing speed.
The obtaining unit 132 is configured to obtain a target firmware source program file corresponding to the target customization identification information according to a corresponding relationship between preset customization identification information and a firmware source program file and the target customization identification information, and send the target firmware source program file to the compiling component.
The obtaining unit 132 is further configured to, if the user identification information is general identification information, directly obtain a general firmware file matched with the user identification information without compiling, and send the general firmware file to the display device 20 through the transceiving component.
In the embodiment of the present application, the display device 20 adopts an upgrading mode that is divided into a general firmware file mode upgrading and a customized firmware file mode upgrading, the general firmware file mode upgrading is to meet the upgrading requirement of most display devices, in order to further improve data security and improve yield, reduce rework and improve user experience, the customized firmware file mode upgrading can be adopted only through authentication verification, and the original firmware source program file is upgraded into the customized firmware file.
In this embodiment, the authentication component verifies whether the user identification information received by the transceiving component is preset customized identification information, so that the security can be improved, the risk of data damage caused by unauthorized operation can be avoided, and the customer satisfaction is reduced while unnecessary after-sale service requirements are generated.
Then, after receiving the configuration file and the prompt that the verification passes, the compiling component 12 is specifically configured to:
updating the identification information in the target firmware source program file into target customized identification information; the identification information is a user ID, i.e., version number information.
And compiling the configuration file and the updated target firmware source program file to generate a customized firmware file.
In this embodiment, since the configuration information in the configuration file of the receiving card is written into a readable and writable unit such as a RAM and/or a register inside the FPGA, when the server compiles the firmware source program file, it may be determined through the configuration file that the receiving card configures an initial value after being powered on, after receiving the uploaded configuration file, first package and integrate the information of the configuration file of the receiving card into a corresponding project configuration file, then perform compilation work on the firmware source program file through the FPGA, generate a customized firmware file containing the configuration information of the configuration file, and change a user ID stored in the customized firmware file to a customized ID, where the customized firmware file may be downloaded to a user through the internet after being generated. The related development technologies such as logic locking, user reconfiguration and the like are provided in the FPGA development tool, so that the integrity and the safety of the customized firmware file generated by the invention can be effectively ensured.
It should be noted that, after the compiling component 12 generates the customized firmware file, the customized firmware file and the target customized identification information are also stored in an associated manner. In this way, when the user inputs the same user identification information again, the server recognizes that the customized firmware file corresponding to the user identification information is already stored in the database through the association relationship, and then directly acquires the stored customized firmware file to send to the display device 20 for upgrade configuration without compiling again, so that the operation is reduced, and the processing efficiency is improved.
The FPGA firmware source program file of the core of the invention is stored in a manufacturer server, and is protected from illegal invasion and acquisition by authorization protection measures such as a hardware firewall, user authentication and the like, thereby effectively ensuring the core intellectual property of an LED control system manufacturer and providing the maximum flexibility of customizing the firmware file configurable by a user.

and the field engineer inputs a user ID into the server through a computer in the LED display screen and uploads a configuration file to the server. And the server receives the user ID and the configuration file sent by the display device through a transceiving component. The authentication component verifies whether the user ID received by the transceiving component is a preset customized ID, if the user ID is verified to be passed, a firmware source program file corresponding to the preset customized ID is obtained in a preset firmware source program file library, the compiling component automatically loads a customized program, compiles the configuration file sent by the transceiving component and the firmware source program file obtained by the authentication component, and automatically generates a customized firmware file. And the field engineer downloads a customized firmware file containing the configuration file information of the receiving card from the server through the display device, and updates the customized firmware file to the FPGA nonvolatile storage space in the receiving card by using a firmware upgrading program. Before the upgrade operation action is executed, the firmware upgrade program will check the user ID of the existing firmware of the receiving card, and execute the following operations: and verifying whether the user ID is the preset customized ID, if so, upgrading the firmware file by customizing the firmware file, and if not, upgrading the firmware file by adopting the general firmware file without executing the upgrading of the customized firmware file. The safety of the firmware file is ensured through the comparison operation. And packaging and delivering the screen customized firmware file after upgrading is completed, and the customized firmware file does not need to be adjusted subsequently.
