Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
As shown in fig. 1, the present invention further provides a method for obtaining a module correction coefficient applied to an LED screen, including:
step S1: coding each module to be used, respectively associating the codes with the correction coefficients corresponding to each module, and storing the codes into a FLASH of a storage chip corresponding to the module;
in specific implementation, when each module to be used is coded, the coding is carried out according to a preset coding table, and the code of each module is a unique code. In addition, the preset coding table is coded according to a binary form.
In this step, the module codes correspond to the correction coefficients thereof one to one, and the coded data content is small, so that the space is not occupied. The implementation is more convenient. And a unique coding mode is adopted, so that the operation is more single.
The mode of operation at restart power-up is as follows:
step S2: when the modules are powered on for the first time, reading codes of the modules corresponding to the current display positions, and storing the codes and correction coefficients corresponding to the modules into FLASH of receiving cards corresponding to all the modules according to the relationship of the display positions;
during specific implementation, the codes are stored in the record tables of the receiving cards corresponding to the modules according to the relationship of the display positions, the correction coefficients stored in the storage chip are directly obtained according to the codes, and the correction coefficients are stored in the record tables of the receiving cards corresponding to all the modules according to the corresponding relationship between the correction coefficients and the codes; and the record table stores the coding and correction coefficients corresponding to each module according to the display position of the module in the screen body in an associated manner. That is, in this step, the codes, correction coefficients and display positions of the modules are associated with one another and stored in the record table of the corresponding receiving card. It should be noted that, in general, the plurality of modules in this embodiment only correspond to one receiving card, where the plurality of modules are combined into one box body, and one box body corresponds to one receiving card.
The correction coefficient and the display position of the module can be inquired through coding, or the coding and the correction coefficient of the module can be known through the display position, so that the module is very simple and convenient.
Step S3: carrying out second power-on operation on the module, enabling the receiving card to send a detection frame to a storage chip in the module according to a preset time interval, and enabling the storage chip to return a feedback frame aiming at the detection frame;
in practice, the time interval may be preset to 6S, and, if,
(1) the receiving card sends a detection frame to the memory chip in the module according to the preset time interval 6S, and in the first time interval, the memory chip returns a feedback frame to the detection frame, so that the module is proved not to be detached and replaced, and at this time, step S5 can be executed.
(2) If the receiving card sends the detection frame to the memory chip in the module according to the preset time interval, if the detection frame is returned by the memory chip in the second time interval, and the second time interval is greater than the first time interval, it is proved that the module is disassembled, that is, the module is reassembled, and at this time, step S4 may be executed.
Step S4: reading the codes of the modules corresponding to the current display positions, and judging whether the codes are consistent with the codes in the step S2; if yes, go to step S5, otherwise go to step S6;
in step S2, the codes, correction coefficients and display positions of the modules are associated with each other in the record table of the corresponding receiving card; therefore, by reading the code corresponding to the current presentation position, the comparison is made with the codes in the record table:
if yes, step S5 is executed, i.e., the correction coefficient corresponding to the module in step S2 is used as the target correction coefficient for correcting the module; taking a correction coefficient in a FLASH of a storage chip corresponding to the module as a target correction coefficient;
if not, step S6 can be executed, i.e., it is further determined whether the inconsistent modules are only due to the variation of the display positions; if the display position is not changed, similarly, the correction coefficient corresponding to the module in step S1 is used as the target correction coefficient for correcting the module; taking a correction coefficient in a FLASH of a storage chip corresponding to the module as a target correction coefficient; if the display position is changed, the correction coefficient corresponding to the display position in the record table in step S2 is used as the target correction coefficient for the module correction.
In the above scheme, when the method is implemented, the codes of the modules, the corresponding correction coefficients and the corresponding display positions are associated, and the codes with smaller data content are read to determine whether the modules are disassembled and replaced or to confirm which module is disassembled and replaced; and when the reading mode during restarting power-on and the reading mode during live working are adopted, the disassembly replacement of the module is determined in different modes so as to automatically obtain the correction coefficient of the new module after the disassembly replacement, and when the screen body is confirmed to work normally, the correction result is not affected, so that the correction efficiency is improved.
Compared with the method that the correction coefficients of all the modules are directly stored in the storage chip, the embodiment avoids the problem that the correction coefficients of the storage chip need to be read back to the receiving card every time, so that the performance of the storage chip is influenced; on one hand, the content of the code is small, and the code does not occupy too much storage space; on the other hand, the codes, the correction coefficients and the display positions of the modules are stored in the receiving card, so that the influence on the performance of the storage chip is avoided, the correction coefficients of the replaced modules can be automatically acquired, and the efficiency is higher.
The reading mode during the charged normal operation is as follows:
when the screen body works normally, the receiving card is enabled to send detection frames to a storage chip in the module according to a preset time interval (such as an interval of 6 seconds), and if the module cannot be detected by the detection frames continuously for a preset number of times, namely the detection frames returned by the storage chip are not received, the module position which cannot be detected is marked. Subsequently, the receiving card continuously sends detection frames to a storage chip in the module according to a preset time interval, if a new module is detected at the marked module position, the currently detected code of the new module is read, and whether the code is consistent with the unique code recorded at each display position in the record list is judged; in specific implementation, the continuous preset times can be set to be 3 times or more.
If yes, go to step S5, i.e. take the correction coefficient corresponding to the module in step S2 as the target correction coefficient for the module correction; taking a correction coefficient in a FLASH of a storage chip corresponding to the module as a target correction coefficient;
if not, go to step S6, i.e. it needs to be further determined whether the inconsistent module is only due to the variation of the display position; if the display position is not changed, similarly, the correction coefficient corresponding to the module in step S1 is used as the target correction coefficient for correcting the module; taking a correction coefficient in a FLASH of a storage chip corresponding to the module as a target correction coefficient, and storing the code and the correction coefficient of the module into a record table in a correlation manner;
if the display position is changed, the correction coefficient corresponding to the display position in the record table in step S2 is used as the target correction coefficient for the module correction.
In the invention, the memory chip can be replaced by a sending card corresponding to the module; the corresponding coding, correction coefficient and display position are obtained from the sending card, on one hand, the module can be ensured to have the required coding, correction coefficient and display position in the normal operation process, and the problem that the coding, correction coefficient and display position are not suitable is avoided, so that the normal display of the screen body is influenced; on one hand, different versions of the receiving card can be upgraded to avoid the problem that the versions of the receiving card are inconsistent in the same screen body, and the display effect of the screen body is also prevented from being influenced.
