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 fall within the scope of the invention.
The method for splicing and arranging the LED modules in the embodiment of the invention, as shown in fig. 1, comprises the following steps:
step S10: obtaining preset target display resolution and module parameters of a used module; the module parameters include module resolution and module size.
After the module used for the LED display screen is clearly spliced, module parameters are obtained through the step, the module parameters comprise two parameters, namely module resolution and module size, the module resolution is novel in light point arrangement of the module, and for example, the module size of the P2 light plate is as follows: 256mm 128mm, its module resolution is: 128*64.
In addition, the target display resolution is required to be obtained in this step, and the resolution is a preset value, for example, the resolution obtained by splicing a plurality of P2 lamp panels needs to reach 1280×640.
Step S20: calculating a minimum arrangement unit used for splicing according to the target display resolution and the module resolution; the resolution of the minimum arrangement unit is the same as the target display resolution.
As shown in fig. 2 and fig. 3, the resolution of the minimum arrangement unit in the embodiment of the present invention needs to be the same as the target display resolution, and two arrangement modes exist at this time, the first arrangement mode is that the number of the arrangements is obtained by dividing the target display resolution and the module resolution, so that the minimum arrangement unit obtained in this mode is obtained by 10×10 arrangement of P2 lamp panels; another way is to arrange vertically, so that a 5×20 arrangement scheme can be obtained, and the calculation method is as follows: dividing by taking any side of the width or the height of the target display resolution as the dividend, if the width is the dividend, taking the height of the module as the divisor to obtain the column number, and dividing by taking the height as the dividend, and taking the width as the divisor to obtain the row number (5 rows and 20 columns); or conversely 10 rows and 10 columns, both arrangements being possible. In fig. 2 and 3, 101 denotes a module, 10 denotes minimum arrangement units, each minimum arrangement unit consisting of 100 modules.
If the remainder occurs in the calculation process, other types of modules can be selected for splicing according to the value of the remainder so as to achieve the target display resolution.
The steps S10 and S20 can be executed for multiple times, so that the minimum arrangement units with different resolutions are respectively generated for storage, and the LED module splicing can be more rapidly realized in different environments.
Step S30: acquiring a screen splicing instruction; the screen splicing instruction comprises the field space size.
When the specific screen is spliced, the screen size needs to be designed in combination with the field space size, so after the screen splicing instruction is acquired, the corresponding scheme output is performed according to the field space size contained in the instruction, that is, step S40.
Step S40: repeatedly arranging the minimum arrangement units according to the field space size and the module size to obtain a module splicing scheme; the minimum row number and column number of the arrangement units contained in the module splicing scheme are the same.
Combining the previous examples, the resolution of the minimum arrangement unit is 1280×640, since the module size of the P2 panel is: 256mm x 128mm, the size of the smallest arrangement unit is 2560mm x 1280mm, or 1280mm x 2560mm. If the field space is larger, some minimum arrangement units can be spliced more, and if the field space is limited, some minimum arrangement units are arranged less, so that the number of modules of the finally spliced screen is determined according to the field space.
For example, the space for placing the LED display screen on site can be 10 meters wide and 5 meters high, so according to the size of the minimum arrangement unit, how many minimum arrangement units are required for the pre-spliced screen and the arrangement mode can be calculated, the calculation mode is similar to the aforementioned step S20, and it should be noted that the number of rows and columns of the minimum arrangement units included in the module splicing scheme in the embodiment of the present invention are the same, so the embodiment can obtain the final module splicing scheme by arranging 3*3 by the minimum arrangement units, as shown in fig. 2 and 3.
If the space for placing the LED display screen on site is up to 12 m wide and 5 m high, the finally obtained module splicing scheme still carries out 3*3 arrangement for the minimum arrangement units based on the same requirement of the minimum arrangement units in the module splicing scheme in the embodiment of the invention on the number of rows and the number of columns. If the space for placing the LED display screen on site reaches 8m wide and 5 m high, the finally obtained module splicing scheme still carries out 3*3 arrangement for the minimum arrangement units based on the same requirement of the minimum arrangement units in the module splicing scheme in the embodiment of the invention on the number of rows and the number of columns. If the space for placing the LED display screen on site reaches 12 m wide and 7 m high, the finally obtained module splicing scheme still carries out 4*4 arrangement for the minimum arrangement units based on the same requirement of the minimum arrangement units in the module splicing scheme in the embodiment of the invention on the number of rows and the number of columns.
Step S50: and determining screen wiring data corresponding to the module splicing scheme according to a preset wiring inlet and a wiring mode.
After the module splicing scheme is determined, final screen wiring data are determined according to a preset wiring inlet and a wiring mode. Specifically, as shown in fig. 4, the present step includes:
step S501: according to the number N of the wiring inlets, the modules contained in the module splicing scheme are divided into N display units, and the N display units are respectively in one-to-one correspondence with the N wiring inlets.
When the number of modules is large, a plurality of wire inlets are usually arranged, so that the modules in the module evaluation scheme are divided according to the number N of the wire inlets, N display units with the same number as the wire inlets are obtained through division, and the N display units are in one-to-one correspondence.
Step S502: and generating a first routing table of each display unit by taking each routing entry as a starting point according to a preset routing mode.
The routing mode can be set by itself, for example, a serpentine routing, and the embodiment is not limited specifically.
Step S503: and taking the position information of the first routing table and the corresponding display unit as screen routing data.
Through the steps, screen wiring data associated with the wiring inlet is obtained, and the data can be used for data processing during subsequent spliced screen display.
Specifically, step S501 in the embodiment of the present invention: according to the number N of wiring entry, divide into N display element with the module that contains in the module concatenation scheme, include:
and obtaining the number X and the number Y of the rows of the modules in the module splicing scheme. For more clearly describing the design concept of the present invention, taking fig. 5 as an example, the values of the number of rows X and the number of columns Y in the module splicing scheme are x=4 and y=6, respectively.
Calculating a=x/N and b=y/N, and judging whether a and B are integers.
Taking n=2, n=3, n=4, n=5, n=6, n=7 as an example, the values of the relevant parameters are shown in table 1 below:
TABLE 1
Therefore, if both a and B are integers, the modules included in the module splicing scheme are divided into N display units from top to bottom or from left to right, the number of modules included in each display unit is equal, and the positions of the modules in each display unit are connected.
If A is an integer and B is not an integer, the modules included in the module splicing scheme are divided into N display units from top to bottom, the number of the modules included in each display unit is equal, and the positions of the modules in each display unit are connected.
If B is an integer and A is not an integer, the modules included in the module splicing scheme are divided into N display units from left to right, the number of the modules included in each display unit is equal, and the positions of the modules in each display unit are connected.
All three cases are cases in which A or B is an integer, and the display unit obtained by the method is rectangular and can be divided in order according to the direction of rows or columns. In the dividing manner of the positions of the dashed lines in fig. 6 and fig. 7, a first routing table of each display unit is generated by taking each routing entry as a starting point according to the serpentine routing manner, as indicated by the arrow lines.
If both a and B are not integers, a first connection trace is generated according to the module positions in the module splicing scheme, such as an arrow trace shown in fig. 8, the first connection trace is divided into N segments, and the modules included in each segment form a display unit.
More specifically, if a and B are not integers and the value of a or B is greater than 1, dividing the modules included in the module splicing scheme into N display units from top to bottom or from left to right, where each display unit includes at least one whole row or one whole column of modules, and each display unit is rectangular. Corresponding to the case where n=5, the value of B is 1.2, so the display units are divided from left to right, each display unit includes at least one whole column of modules, and the corresponding division manner may be: the first column of modules forms the 1 st display unit, the second column of modules forms the 2 nd display unit, the third column of modules forms the 3 rd display unit, the fourth column of modules forms the 4 th display unit, and the fifth and sixth columns of modules form the 5 th display unit together.
Specifically, in the embodiment of the present invention, a first connection trace is generated according to a module position in a module splicing scheme, the first connection trace is divided into N segments, and modules included in each segment form a display unit, including:
calculating the quotient of the number M of the modules and the number N of the routing entries in the module splicing scheme to be C, and the remainder to be D; C. d is an integer greater than 1. As shown in fig. 5, the module splicing scheme includes m= 4*6 =24 modules, and since the calculation a and B are not integers, n=5 is assumed, so c=4 and d=4 are obtained.
Starting from the first module in the first connection trace, every C modules serve as a display unit, and the last display unit comprises D modules to obtain N display units. Therefore, the 1 st display unit includes 5 modules, the 2 nd display unit includes 5 modules, the 3 rd display unit includes 5 modules, the 4 th display unit includes 5 modules, and the 5 th display unit includes 4 modules, as shown in fig. 9, the dotted line shows the division mode of the display units.
Or, the present invention further includes another embodiment, generating a first connection trace according to a module position in a module splicing scheme, dividing the first connection trace into N segments, and forming a display unit from modules included in each segment, including:
calculating the quotient of the number M of the modules and the number N of the routing entries in the module splicing scheme to be C, and the remainder to be D; C. d is an integer greater than 1.
Starting from the first module in the first connecting wiring, every C+1 modules are used as a display unit, D display units are divided, and every C modules are used as a display unit after D display units are divided, so that N display units are obtained.
As shown in fig. 5, the module splicing scheme includes m= 4*6 =24 modules, assuming n=7, c=3 and d=3.
Starting from the first module in the first connecting wiring, every C+1 modules are used as a display unit, D display units are divided, and every C modules are used as a display unit after D display units are divided, so that N display units are obtained. So the 1 st display unit comprises 4 modules, the 2 nd display unit comprises 4 modules, the 3 rd display unit comprises 4 modules, the 4 th display unit comprises 3 modules, the 5 th display unit comprises 3 modules, the 6 th display unit comprises 3 modules, and the 7 th display unit comprises 3 modules.
Step S501 of the embodiment of the present invention: according to the number N of the wiring inlets, divide the module that contains in the module concatenation scheme into N display element, still include:
judging whether the number N of the wiring inlets is larger than the number X and the number Y of the rows of the modules in the module splicing scheme.
If N is larger than X, N is larger than Y, and Y is larger than X, resetting the number of the wiring inlets to Y, and dividing the modules contained in the module splicing scheme into Y display units from left to right.
Assuming that n=7, x=4, and y=6, the number of routing entries is reset to 6, and the modules included in the module splicing scheme are divided into 6 display units from left to right, and each column of modules forms one display unit. In this way, instead of using all the routing entries, the number of routing entries is selected to be consistent with the number of columns or rows, so that the display unit is conveniently divided into rectangular shapes.
If N is greater than X, N is greater than Y, and X is greater than Y, resetting the number of the wiring inlets to X, and dividing the modules contained in the module splicing scheme into X display units from top to bottom.
Assuming that n=7, x=6, and y=4, the number of routing entries is reset to 6, and the modules included in the module splicing scheme are divided into 6 display units from top to bottom, and each row of modules forms one display unit.
If N is more than or equal to X and N is less than or equal to Y, dividing the modules contained in the module splicing scheme into N display units from left to right.
Assuming that n=5, x=4, and y=6, the modules included in the module splicing scheme are divided into 5 display units from left to right, that is, are divided in a column manner, for example, a first column of modules forms a 1 st display unit, a second column of modules forms a 2 nd display unit, a third column of modules forms a 3 rd display unit, a fourth column of modules forms a 4 th display unit, and a fifth column of modules and a sixth column of modules form a 5 th display unit together.
If N is less than or equal to X and N is more than or equal to Y, dividing the modules contained in the module splicing scheme into N display units from top to bottom.
Assuming that n=5, x=6, and y=4, the modules included in the module splicing scheme are divided into 5 display units from top to bottom, i.e. according to a row manner, for example, a first row of modules forms a 1 st display unit, a second row of modules forms a 2 nd display unit, a third row of modules forms a 3 rd display unit, a fourth row of modules forms a 4 th display unit, and a fifth and sixth rows of modules form a 5 th display unit together.
If N is less than X and N is less than Y, the modules contained in the module splicing scheme are divided into N display units from left to right, or the modules contained in the module splicing scheme are divided into N display units from top to bottom.
Assuming that n=2, x=4, and y=6, the modules included in the module stitching scheme are divided into 2 display units from left to right, or the modules included in the module stitching scheme are divided into 2 display units from top to bottom, where both the dividing modes are acceptable.
