[0040] To make the invention purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] The present invention provides an adaptive startup method for an LED splicing wall, which is used to solve the problem that the current at the LED display unit is too large and causes damage when the startup power supply module is instantaneously turned on in the prior art.

[0042] Please refer to Figure 1 , Figure 1 which is the first flow chart of the adaptive startup method for the LED splicing wall provided by the embodiment of the present invention.

[0043] S100, obtain the correspondence between the brightness values and voltage values of each receiving card in the LED splicing wall;

[0044] It should be noted that each display unit in the LED splicing wall is controlled by a corresponding receiving card. The power supply module outputs power to the LED diodes after being controlled by the receiving card to achieve LED brightness adjustment; therefore, when the brightness values set on the receiving card are different, the voltage values of the receiving card are also different;

[0045] After the LED splicing wall has been used for a period of time, the aging of the LED diodes will cause an increase in their internal resistance, resulting in a change in the voltage value of the receiving card at the same brightness value, and the correspondence between the brightness values and voltage values of different receiving cards is different. Therefore, each receiving card needs to obtain its own correspondence between the brightness value and the voltage value.

[0046] S200. Calculate the average voltage of each receiving card according to the voltage values of each receiving card at different brightness values, and then take the average value of the average voltages as the startup voltage value of the LED splicing wall.

[0047] It should be noted that the average voltage of the receiving card reflects the overall voltage situation within the brightness value range after a period of use of the corresponding display unit; while the startup voltage value of the LED splicing wall reflects the overall voltage situation within the brightness value range of the entire LED splicing wall system in combination with the voltage situations of each display unit. Therefore, the startup voltage value is applicable to each display unit.

[0048] S300. Before starting the power supply module, according to the correspondence between the brightness value and the voltage value of each receiving card, select the brightness value corresponding to each receiving card with the startup voltage value and set it as the startup brightness value of each receiving card.

[0049] It should be noted that the startup voltage value corresponds to different brightness values in each display unit. After setting the startup brightness value corresponding to the startup voltage in each receiving card and starting the power supply module, with the overall input voltage of the LED splicing wall remaining unchanged, the power consumption of each receiving card in the LED splicing wall is evenly started, so that the current in each display unit will not be too high, ensuring the safety of the display unit, and reducing the loss of the display unit and the maintenance cost.

[0050] In this embodiment, by obtaining the correspondence between the brightness value and the voltage value of each receiving card in the LED splicing wall; calculating the average voltage of each receiving card respectively, and then calculating the average value of the average voltages, the startup voltage value of the LED splicing wall is obtained as the voltage standard to meet the brightness change of each display unit; before starting the power supply module, according to the correspondence between the brightness value and the voltage value of each receiving card, select the brightness value corresponding to the startup voltage value of each receiving card and set it as the startup brightness value of each receiving card, so that when the power supply module starts, the voltages between the display units are balanced, and all can start working with a safe current, ensuring the operation safety of the display unit.

[0051] The above is the detailed description of the first embodiment of an adaptive startup method for an LED splicing wall provided by this application. The following is the detailed description of the second embodiment of an adaptive startup method for an LED splicing wall provided by this application.

[0052] In this embodiment, a specific embodiment of step S100 in an adaptive startup method for an LED splicing wall is further provided. Please refer to Figure 2 , step S100 specifically includes steps S101 - S102, and the details are as follows:

[0053] S101. The LED splicing software control system establishes a network connection with the transmitter and connects to each receiving card through the network port of the transmitter.

[0054] It should be noted that the control link of the LED splicing wall is as follows: The LED splicing software control system is connected to the transmitter through a network cable. The transmitter is connected to the receiving card through the network port output. The receiving card controls the power output of the display unit to adjust the brightness of the display unit.

[0055] The LED splicing software control system controls the transmitter through a pure software control method, enabling the transmitter to send brightness value adjustment commands to different receiving cards and obtain receiving card information. The IP of the transmitter is recorded on the interface of the LED splicing software control system, and the network port serial number of the transmitter and the serial number of the receiving card loaded by the network port are recorded. The specific steps in the control system are as follows:

[0056]

[0057] S102. Establish a data table for each LED receiving card. The LED splicing software control system traverses the voltage values of each receiving card at each brightness value through a network command and stores them in the data table.

[0058] It should be noted that the brightness values of the receiving cards in the data table are set from small to large as 0 - 255, a total of 256 values. After setting the receiving cards in sequence with an increment of 256 brightness values, the corresponding receiving card voltage values are read to obtain the corresponding relationship between the brightness values and voltage values of each receiving card. It can be understood that the brightness value of the LED changes with the brightness adjustment of the RGB three primary colors, and the overall brightness does not increase uniformly with the voltage. Therefore, the corresponding voltage value needs to be obtained for each brightness value.

[0059] In actual implementation, first establish a data table in the control system for storing the corresponding relationship between the brightness values and voltage values of the receiving cards. Then send brightness setting commands to all the receiving cards in the table, set the brightness values incrementally from 0 to 255 in sequence. While setting each brightness value, obtain the voltage value of the receiving card to get the corresponding relationship and store it in the data table. The data structure of the table is structVoltyInfo. The specific steps in the control system are as follows:

[0060]

[0061] In this embodiment, by setting the network connection between the LED splicing software control system and the transmitter, and between the transmitter and each receiving card through the network port, it enables the staff to remotely control the receiving cards of each display unit through the software, obtain receiving card information, control the receiving cards to obtain the corresponding relationship between the brightness values and voltage values, and establish a data table, improving the startup efficiency of the LED splicing wall.

[0062] The above is the detailed description of the second embodiment of an LED splicing wall adaptive startup method provided by this application. Next is the detailed description of the third embodiment of an LED splicing wall adaptive startup method provided by this application.

[0063] In this embodiment, a specific embodiment of step S300 in an LED splicing wall adaptive startup method is further provided. Please refer to Figure 3 , step S300 specifically includes steps S301 - S302, details are as follows:

[0064] S301, according to the correspondence between the brightness values and voltage values of each receiving card, select the brightness values corresponding to the startup voltage values of each receiving card;

[0065] It should be noted that by traversing the data table structVoltyInfo, obtain the brightness values corresponding to each receiving card at the startup voltage value. If there is a receiving card in the data table without this startup voltage value, then select the brightness value corresponding to the voltage value closest to the startup voltage value;

[0066] Furthermore, although the voltage balance of each receiving card of the LED splicing wall ensures the safety of the display unit, the startup brightness of each display unit may vary, resulting in a poor overall display effect of the LED splicing wall and being troublesome in subsequent brightness adjustment. Therefore, in actual implementation, a safe startup voltage value range can be set based on the startup voltage value according to the actual usage of the display unit, and select the brightness values as close as possible in the receiving card according to the corresponding relationship in the data table. For example, calculate the average value of the brightness values of all receiving cards within the safe startup voltage value range, and select the brightness value of each receiving card closest to this average value. On the premise of ensuring the safety of each display unit, make the overall brightness difference of the LED splicing wall more uniform.

[0067] S302, after the LED splicing software control system sets the selected brightness value as the startup brightness value of each receiving card, send an LED power module startup instruction.

[0068] It should be noted that the LED splicing software control system sets the corresponding brightness value for the receiving card of each display unit through the transmitter, and then controls the power supply to turn on by sending a startup instruction to ensure that the current of the display unit will not be too high when the power module starts up.

[0069] Furthermore, in a more specific embodiment, the calculation method of step S200, which calculates the average voltage value of each receiving card according to the voltage values of each receiving card at different brightness values, and then takes the average value of each average voltage value as the startup voltage value of the LED splicing wall, is specifically as follows:

[0070] Let the number of receiving cards of the LED splicing wall be N, and the average voltage value of receiving card a at 256 voltage values m be Ma , M a = (m a0 + m a1 + … + m a254 + m a255 ) / 256; The startup voltage value of the LED splicing wall is F, and F = (Ma + Mb + … + Mn) / N.

[0071] The specific steps in the control system are as follows:

[0072]

[0073] Further, in step S301, if there is no corresponding value of F for the receiving card in the data table structVoltyInfo, then traverse the data table structVoltyInfo to select the brightness value corresponding to the voltage value of the closest F.

[0074] Further, to ensure the safety of the display units of the LED splicing wall, the data table needs to be recalibrated along steps S100 - S300 every preset time, and the startup brightness value of the receiving card is reset. This preset time is set according to the actual situation and can generally be three months or half a year.

[0075] In this embodiment, by calculating the average voltage of each receiving card and the startup voltage of the splicing wall, the appropriate brightness value of each receiving card is selected, so that the voltage of each display unit is uniform when the power module starts, ensuring its safe operation. Further, a safety range is set based on the startup voltage value, so that the brightness difference of each display unit can be reduced when starting, improving the usage efficiency of the LED splicing wall, reducing the loss of display units, and increasing its service life.

[0076] The above is the detailed description of the third embodiment of an LED splicing wall adaptive startup method provided by this application. Next is the detailed description of an LED splicing wall adaptive startup device provided by the second aspect of this application.

[0079] A safety voltage value calculation module 20, which is used to calculate the average voltage of each receiving card respectively according to the voltage values of each receiving card at different brightness values, and then take the average value of each average voltage as the startup voltage value of the LED splicing wall;

[0080] The startup brightness value setting module 30 is activated, which is used to select the brightness value corresponding to each receiving card according to the corresponding relationship between the brightness value and the voltage value of each receiving card before activating the power supply module, and set it as the startup brightness value of each receiving card.

[0081] The third aspect of this application also provides an LED splicing wall adaptive startup device, including a processor and a memory: wherein the memory is used to store program code and transmit the program code to the processor; the processor is used to execute the LED splicing wall adaptive startup method of the first aspect according to the instructions in the program code.
