Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. The embodiments of the present application and the features in the embodiments may be combined with each other without collision.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
The scanning card sharing method of each embodiment of the application can realize the sharing of the scanning cards among a plurality of modules of different boxes, thereby reducing the number of the scanning cards of the LED spliced display screen, reducing the cost of the spliced display screen and simultaneously reducing the load surplus of the scanning cards.
The scan card sharing method according to the embodiments of the present application will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a schematic flow chart of a scan card sharing method according to an embodiment of the present application is shown, and the scan card sharing method can be applied to the sharing of scan cards between multiple modules of the same box and between multiple modules of different boxes, so that the LED unit box meets multiple splicing modes. As shown in fig. 1, the scan card sharing method includes the steps of:
s10: acquiring upper computer box parameters;
typically, one LED unit box only completes a partial display of one complete image frame, and a large LED tiled display screen may include several tens of hundreds of boxes, with all boxes together completing the display of one image frame. All the boxes are connected to a control system, and each box displays a part of an image frame under the allocation of the control system, so that the image display work is completed. In the working process, the control system sends the upper machine box parameters to each box body, and the scanning card can determine the loaded image information after receiving the upper machine box parameters.
In some of these embodiments, the upper box parameters include pixel height and pixel width. For example, the LED tiled display screen may be calibrated before operation, and during calibration, a set of calibration parameters is configured and sent to the scan card of each box. The upper computer box parameters can comprise correction parameters, and the load range can be determined after the scanning card receives the upper computer box parameters. The upper computer box parameters can be parameter matrixes, parameter information can be obtained directly from the parameter matrixes, and also can be image information, for example, a control system sends a part of an image frame to a scanning card of each box, and after the scanning card receives a part of the image frame, the box parameter information such as pixel height, pixel width and the like can be obtained indirectly through analysis of the image frame.
It will be appreciated that the upper computer parameters may also include other information such as sweep number, bin position, etc.
S20: analyzing the parameters of the upper machine box body, and confirming the matching degree of the scanning card to the box body;
after the scanning card receives the upper computer parameters sent by the control system, the upper computer parameters are analyzed, and whether the scanning card is matched with the box body or not is confirmed according to the analysis result.
For example, when the pixel height and the pixel width are obtained through parameter analysis of an upper computer, the scanning card obtains a loading range, the pixels in the loading range are compared with the loading capacity of the scanning card, if the pixels in the loading range do not exceed the loading capacity of the scanning card, the scanning card is considered to be matched with the box body, and the scanning card can finish image loading in a preset range; otherwise, the scan card is considered to be unmatched, and the scan card is loaded according to a default rule.
S30: if the scanning card is matched with the box body, generating a module number, and transmitting the module number to a plurality of modules connected with the scanning card;
after determining that the scanning card has the capability of carrying the image in the preset range, the scanning card numbers the plurality of modules and sends the corresponding numbers to the corresponding modules.
In the process of the LED display screen, each box body is electrically connected with one scanning card, and one scanning card can be connected to a plurality of box bodies. Referring to fig. 3, taking a scan card shared by two boxes as an example, the modules of the two boxes may be connected to the scan card through a flat cable to establish an electrical connection between the scan card and the modules of the two boxes, and to be able to perform data transmission.
The scanning card can be provided with a plurality of interfaces to realize electric connection and data connection with a plurality of modules, so that the scanning card can obtain the number of the modules connected with the scanning card through interface information and number the modules according to a preset rule. For example, the modules are numbered according to the natural number sequence of "1, 2, 3, 4, 5 and … …", and of course, the natural number sequence number is only the simplest rule example, and can be customized in specific execution. In a specific embodiment, in order to reduce the number of wires between the boxes, one module may correspond to one interface, so that the scan card may number the interface, that is, the number of the module connected to the interface, so as to indirectly number the module.
After the scanning card numbers the module, the module needs to be notified so as to facilitate the data interaction between the scanning card and the module. The notification mode can be performed in a handshake mode, corresponding number information is sent to the corresponding module by the scanning card, and after the module receives the number information, feedback information is returned to the scanning card to confirm that the module knows the number of the module.
S40: and establishing a data transmission channel between the module and the scanning card.
And numbering all the modules connected with the scanning card, and after receiving feedback information of the modules, the scanning card can confirm the position information of each module and establish a data transmission channel between the modules and the scanning card so as to facilitate subsequent image display.
When the image display is carried out, the control system sends the image information carried by the scanning card to the scanning card, or the scanning card directly intercepts the corresponding partial image information from a complete image frame, and then the scanning card distributes the partial image information to each module for display. The scanning card confirms the relative position information of each module when receiving the feedback information, so that the scanning card can distribute images according to the position information of each module, and each module can complete correct display of the images.
Referring to fig. 2, in one or more embodiments, the step S20: analyzing the upper computer box parameters, and confirming the matching degree of the scanning card to the box, specifically comprising:
s210: resolving pixel height and pixel width from the upper computer box parameters to form a virtual pixel array;
s220: and confirming whether the scanning card can carry the virtual pixel array or not, and if so, matching the scanning card with the box body.
For the box, a pixel display with a regular shape is generally provided, for example, the box is rectangular, the parameters of the upper computer box are analyzed to obtain a pixel height and a pixel width, a virtual pixel array can be obtained according to the pixel height and the pixel width according to the rule of rectangular display, and if the scanning card can load the virtual pixel array, the scanning card can meet the load requirement of the upper computer, and the scanning card is considered to be matched with the box.
Referring to fig. 3, an exemplary box group is shown, the box group is formed by splicing two left and right unit boxes, the left and right unit boxes comprise 3*1 array display modules, the scan card is arranged on the right box, the pixel specification of each display module is defined as 480 x 480, and the carrying capacity of the scan card is greater than 1440 x 960. If the pixel height sent from the upper computer is less than 1440 and the pixel width is less than 960, the scan card is matched with the box, otherwise, the scan card is not matched.
The control system sends the upper computer box parameters according to the pixel specification of the display module, the pixel height in the upper computer box parameters is generally M times of the pixel height of the display module, the pixel width in the upper computer box parameters is generally N times of the pixel width of the display module, and M, N is a positive integer.
Referring to fig. 4, in one or more embodiments, step S30: if the scan card is matched with the box, a module number is generated and sent to a plurality of modules connected with the scan card, the method can comprise the following sub-steps:
s310: acquiring a pixel array of a single module;
s320: determining the arrangement shape of a plurality of modules according to the pixel array and the virtual pixel array of the single module;
s330: numbering the modules according to the preset rule according to the arrangement shape of the modules;
s340: the serial numbers of the modules are sent to a plurality of modules connected with the scanning card.
After the scanning card is determined to be matched with the box body, the scanning card can completely display the image frames sent by the control system, so that the space arrangement of a plurality of modules conforming to the display rule can be predetermined for facilitating the image display distribution of the scanning card, and the modules are numbered according to the space arrangement.
The pixel array model of a single module can be stored in the scanning card, and the virtual pixel array can be spliced by the pixel array models of a plurality of modules, so that the arrangement shape among the plurality of modules for completing image display can be obtained. The pixel array of the single module may also be sent by the control system, including within the upper box parameters.
For example, referring to fig. 5, if the pixel array of a single module is 480×480 (as in fig. 5 a) and the virtual pixel array is 1440×960, the plurality of modules need to be arranged according to 3 rows and 2 columns, and can correspond to the display rule of the virtual pixel array, and at this time, the splicing between two boxes may be left-right splicing, and the modules may be numbered according to the rule of left-right splicing (as shown in fig. 5 b). If the virtual pixel array is 960×1440, the multiple modules need to be arranged in 2 rows and 3 columns, which can correspond to the display rule of the virtual pixel array, and at this time, the splicing between the two boxes may be up-and-down splicing (as shown in fig. 5 c), and the modules may be numbered according to the up-and-down splicing rule.
When numbering the modules according to a preset rule, firstly numbering a plurality of virtual modules virtually spliced into a virtual pixel array according to the arrangement and splicing relation of the single module and the virtual pixel array, then corresponding the numbers to the actual modules one by one, and sending the numbers to the modules, namely completing the numbering of the modules.
Referring to fig. 6, in one or more embodiments, step S40: the data transmission channel is established between the module and the scanning card, and the method can comprise the following substeps:
s410: receiving position information and identity identification information of a plurality of modules in a box body, which are sent by the modules;
s420: the serial numbers of the modules are in one-to-one correspondence with the modules, and a data transmission channel is established between the scanning card and the modules.
After the scanning card numbers the modules, the numbers are required to be in one-to-one correspondence with the actual modules so as to realize correct image distribution during image display, and ensure that a plurality of modules can correctly complete image display.
After the number of each module is determined, the number of each module is sent to the module, namely, one-time data transmission between the scanning card and each module is completed, and a data transmission channel is established between the scanning card and the module. It will be appreciated that the location information and the identification information of the modules may be stored in the modules, and that the location information may be obtained by communication between the modules.
For example, when the scan card indirectly numbers the module through the serial numbers of the interfaces, the scan card can correspond the serial numbers to the module only by receiving the position information and the identity information from each interface. When virtual numbering is carried out through the virtual pixel array, the numbers and the modules can be corresponding according to virtual arrangement of the modules and position information of each module, and the numbers and the modules can be corresponding by combining with identity identification information of the modules, so that after the number is finished, a scanning card can determine images to be displayed by a specific module.
Referring to fig. 7, in one or more embodiments, step S20: after the step of analyzing the upper computer box parameters and confirming the matching degree of the scanning card to the box, step S40: before the data transmission channel is established between the module and the scanning card, the method can further comprise the following steps:
step S50: if the scan card is not matched with the box, a default module number is called.
If the scanning card is not matched with the box body, namely the parameter prompt of the upper computer sends an image which exceeds the carrying capacity of the scanning card, at the moment, the scanning card numbers the module according to a default rule, and a data transmission channel is established between the scanning card and the module.
For example, the scan card obtains the connection condition of each interface, and arranges each interface according to a default rule. Taking the scan card to provide 6 interfaces as an example, if the scan card scans that 3 interfaces are connected with modules, the modules are numbered according to the rule of 3*1 array, and if the scan card scans that 6 interfaces are connected with modules, the modules are numbered according to the rule of 3*2 or 2*3 array. After numbering is completed, a connection relationship can be established between the module and the scanning card, so that a data transmission channel is established.
It can be understood that when the number of the default rule is called, each interface may be corresponding to a number, and the number corresponds to the location information of the modules arranged in the preset rule.
The scanning card sharing method can realize sharing of the scanning cards among a plurality of modules of different boxes, so that the boxes are suitable for splicing of different scenes, a single box is taken as a 3*1 module array as an example, two boxes are spliced to form a box group, the box group with 3*2 arrays can be formed, at the moment, the box group can be used as a common 3*2 box, when the box group is spliced into a specific shape, if 3*2 boxes are spliced, surplus can exist, at the moment, the box group with 3*2 arrays can be split out of the boxes with 3*1 arrays for splicing, and therefore splicing at gaps is suitable. Meanwhile, the shared scanning card fully utilizes the carrying capacity of the scanning card, so that the carrying surplus of each box is changed into the carrying surplus of the plurality of box shared by the boxes, and the carrying utilization rate of the scanning card is improved.
