The following is illustrated by specific embodiments:

[0055] Please refer to Figures 1 to 6 , Embodiment 1 of the present invention is:

[0056] Such as Figure 1As shown in the figure, a data management device for an LED display screen includes an LED signal processing module 1 and a plurality of LED display modules 2. Specifically, each of the LED display modules 2 includes an adapter board 21 and at least two unit light boards 22; a Flash storage circuit 211 and a display control circuit 212 are provided on the adapter board 21; the LED signal processing module 1 is respectively connected to the input ends of the Flash storage circuit 211 and the display control circuit 212, and the output end of the display control circuit 212 is respectively connected to the unit light boards 22.

[0057] In some embodiments, the display control circuit 212 is specifically a display signal filtering and shaping circuit. Since the display signal will be distorted in waveform due to interference or obstruction during transmission, the display signal filtering and shaping circuit can effectively remove clutter, restore the waveform, and enhance the transmission performance.

[0058] In some embodiments, the unit light board 22 is the smallest unit light board.

[0059] As Figure 2 shown in the figure, the LED signal processing module 1 includes a first connector 11. Specifically, a second connector 213 adapted to the first connector 11 is further provided on the adapter board 21. The first connector 11 is inserted into the second connector 213, and the second connector 213 is respectively connected to the output ends of the Flash storage circuit 211 and the display control circuit 212.

[0060] The LED signal processing module 1 includes a main receiving card 12 and a transmitting card 13. Specifically, the main receiving card 12 is respectively connected to the input ends of the transmitting card 13, the Flash storage circuit 211, and the display control circuit 212, and the transmitting card 13 is used to receive LED control signals.

[0061] In some embodiments, in the LED signal processing module 1, the corresponding LED display screen control program realizes the storage and readback of the calibration data of the unit light board through the transmitting card, the receiving card, the Flash storage circuit, and the display control circuit.

[0062] In some embodiments, the RGB display signal and the control signal sent by the receiving card are transmitted to the corresponding unit light board through the display control circuit, and the Flash storage signal sent by the receiving card is sent to the Flash chip on the adapter board through the Flash storage circuit.

[0063] In an alternative embodiment, the LED signal processing module 1 further includes a backup receiving card 14. Specifically, the backup receiving card 14 is respectively connected to the input ends of the transmitting card 13, the Flash storage circuit 211, and the display control circuit 212.

[0064] In an alternative embodiment, a monitoring enabling circuit 214 is further provided on the adapter board 21. Specifically, the monitoring enabling circuit 214 is respectively connected to the main receiving card 12 and the backup receiving card 14.

[0065] In some embodiments, a data management device for an LED display screen may include four combination types. As Figure 3 shown, combination type 1: includes an LED signal processing module 1 and an LED display module 2. Among them, the LED signal processing module 1 only includes a main receiving card 12 and a transmitting card 13. As Figure 5 shown, combination type 2: includes an LED signal processing module 1 and multiple LED display modules 2. Among them, the LED signal processing module 1 only includes a main receiving card 12 and a transmitting card 13. In the above combination type 1 and combination type 2, a monitoring enabling circuit does not need to be provided on the adapter board 21 of the LED display module 2 to simplify the circuit structure. As Figure 4 shown, combination type 3: includes an LED signal processing module 1 and an LED display module 2. Among them, the LED signal processing module 1 includes a transmitting card 13, a main receiving card 12, and a backup receiving card 14. Combination type 4: includes an LED signal processing module 1 and multiple LED display modules 2. Among them, the LED signal processing module 1 includes a transmitting card 13, a main receiving card 12, and a backup receiving card 14. In the above combination type 1 and combination type 2, a monitoring enabling circuit 214 is provided on the adapter board 21 of the LED display module 2 to realize the switching between the main receiving card 12 and the backup receiving card 14.

[0066] In some embodiments, if the current data management device for the LED display screen includes an LED signal processing module 1 and an LED display module 2, where the LED signal processing module 1 includes a transmitting card 13, a main receiving card 12, and a backup receiving card 14. When the main receiving card 12 is working normally, the main receiving card 12 receives the LED control signal of the transmitting card 13, and communicates with the Flash chip module 2112 on the LED display module 2 through the first connector 11 and the second connector 213 to manage and control the correction coefficients of multiple unit light boards 22 on the LED display module 2 to realize the correction of the LED display screen. When an accident occurs to the main receiving card 12, it is damaged or needs to be repaired, the monitoring enabling circuit 214 is used to switch to the backup receiving card 14 to work, and the backup receiving card 14 executes the steps of the main receiving card 12 to achieve correction.

[0067] In some embodiments, the monitoring and enabling circuit 214 in the LED display module 2 is used to monitor and enable the main receiving card 12 and the backup receiving card 14. Specifically, the monitoring and enabling circuit 214 determines which receiving card is currently working by monitoring the level signals on the pins of the main receiving card 12 and the backup receiving card 14. For example, if the main receiving card 12 is preferentially used for work by default in the device, then at this time, the level signal of the main receiving card 12 received by the monitoring and enabling circuit 214 is a high level, while the level signal of the backup receiving card 14 is a low level. When an unexpected situation occurs to the main receiving card 12, such as damage or the need for repair, at this time, the level signal of the main receiving card 12 received by the monitoring and enabling circuit 214 is a low level. At the same time, the monitoring and enabling circuit 214 sends a high level signal to the backup receiving card 14 to enable the backup receiving card 14 to start working, thereby switching to the backup receiving card 14 for work.

Specifically, the Flash chip module 2112 is respectively connected to the DC-DC power supply module 2111 and the auxiliary circuit module 2113.

[0069] In some embodiments, the auxiliary circuit module 2113 is used for the Flash chip module 2112 to work stably. Since the Flash chip module 2112 requires a specific low-voltage power supply voltage, the DC-DC power supply module 2111 is provided to convert the display screen power supply voltage into the power supply voltage required by the Flash chip module 2112.

[0070] As Figure 6 shown, a plurality of plug-in connectors 215 are further provided on the adapter board 21. Specifically, the output ends of the display control circuit 212 are respectively connected to the plug-in connectors 215, and the plug-in connectors 215 are respectively plugged into the unit lamp boards 22, so that the output ends of the display control circuit 212 are respectively connected to the unit lamp boards 22.

[0071] In some embodiments, the adapter board 21 is specifically a HUB hub, and the adapter board includes a second connector and a plurality of plug-in connectors.

[0072] In an alternative embodiment, the model of the Flash chip module 2112 is W25Q16. The models of the Flash chip modules configured in the present invention include but are not limited to W25Q16, and Flash chip modules with appropriate parameters can be selected according to specific application scenarios and user requirements to implement the above-mentioned data management device for an LED display screen.

[0073] In summary, a data management device for an LED display screen provided by the present utility model integrates a Flash storage circuit, a display control circuit, and multiple unit lamp boards into an LED display module through an adapter board, and then extends and connects multiple LED display modules through an LED signal processing module, broadening the application scenarios of the data management device. In addition, the LED signal processing module and the LED display module are electrically connected based on a connector, and the adapter board and the unit lamp board are electrically connected based on a plug-in component, enabling the LED signal processing module and the LED display module, as well as the adapter board and the unit lamp board, to be freely combined, with convenient operation and facilitating debugging by maintenance personnel. At the same time, since multiple unit lamp boards share a Flash storage circuit on the adapter board and there is no need to separately set a calibration data circuit for each unit lamp board, the circuit structure in the scenario of multiple unit lamp boards is further simplified, effectively reducing the production cost.
