[0002] LED display screens have been widely used in modern society, from billboards, stadium screens to stage backgrounds. Usually, several LED display modules and a receiving module are combined into a box, and then multiple boxes are combined into a large LED display screen. This modular design is not only convenient for transportation and installation, but also can flexibly adjust the size and resolution of the screen according to needs. In the factory, the assembly plant debugs each box according to the customer's requirements to ensure that its electrical connection, display effect and mechanical structure meet the standards. Each box is packaged and sent to the installation site after debugging. At the installation site, the construction personnel need to use network cables to connect the receiving modules of each box according to the actual situation on site to form a complete large screen.

[0043] Embodiment 1

[0044] The embodiment of the present invention provides a method for obtaining connection information of an LED display screen. The method is used in an LED display screen system and is suitable for the installation and debugging of LED display screens, especially in the on-site installation process of large LED display screens. The LED display screen here is composed of multiple boxes, one of which includes a display screen composed of several LED display modules (an LED display module includes many LED lights arranged in an array) and at least one receiving module. The receiving module will receive data sent from a sending module (such as a video processor or a sending card) and light up the corresponding LED display module accordingly. Figure 1 The figure shows the structure of the LED display screen system. Generally, a sending module includes one or more Gigabit Ethernet ports (hereinafter referred to as Ethernet ports). One Ethernet port is connected to multiple receiving modules in series. The control module determines the data transmission according to the connection sequence of the receiving modules connected to each Ethernet port so that the LED display module in each cabinet can correctly display the corresponding picture. Figure 2As shown, ideally, the box positions are installed according to the connection sequence of the network ports and the receiving modules. However, the actual situation is often as described in the background technology. On-site construction personnel may not be able to install them in this ideal sequence, resulting in unclear connection relationships between the receiving modules in each box. Therefore, an embodiment of the present invention provides a method for obtaining connection information of an LED display screen. The method can quickly obtain the connection relationship between the receiving modules in the box, simplify the debugging process, and greatly reduce the time and cost of debugging.

[0045] See also Figure 3 , the LED display screen connection information acquisition method comprises the following steps:

[0046] S1: Assemble multiple cabinets into an LED display screen;

[0047] S2: Connecting the sending module and the receiving modules in each of the boxes;

[0048] S3: driving the control module to send a screen connection command to the sending module;

[0049] S4: When the sending module receives the screen connection command, it sends a lighting instruction to the receiving modules connected to each network port in a preset order. When the receiving module receives the lighting instruction, it drives the LED display module in the box where it is located to light up and display the corresponding preset display content;

[0050] S5: Acquire connection information of the LED display screen according to each of the preset display contents, wherein the connection information includes a connection network port and a connection sequence of each of the boxes.

[0051] Specifically, first, multiple cabinets are assembled into an LED display screen. For example, multiple cabinets are assembled into a rectangular, square, triangular or circular LED display screen of any shape according to the needs of the site or the needs of the designer. The installation position of each cabinet can be determined according to the needs and conditions of the site. It is worth pointing out that the shape and size of each cabinet can be the same, partially the same, or completely different. After the cabinets are assembled, the network ports in the sending module and the receiving modules in each cabinet are connected through the network cable. After the connection is completed, the driving control module sends a screen connection command to the sending module. The control module here can be the control software in the PC end, the smart phone end, and the smart tablet end, which is used to manage and control the display content and working status of the LED display screen. The control module selects and determines the cabinets that need to be connected to the screen, and sends the screen connection command to the sending module. The screen connection command here is used to start and configure the multi-cabinet screen connection display function. After the sending module receives the screen connection command, it will send a lighting instruction to the receiving modules connected to each network in a preset order. The receiving module that receives the lighting instruction will drive the LED display module in the box where it is located to light up and display the preset display content. Preferably, the preset display content is the network port sequence number and the lighting sequence number. After each box is lit up in a preset order and displays the corresponding preset display content, the control module obtains these preset display contents, and obtains the position of the box (or receiving module) connected to each network port and the connection sequence of each box (or receiving module) according to the preset display content. The connection relationship or connection sequence of the network port in each box or receiving module is also called connection information. The subsequent control module can send the connection information to the sending module. The sending module sends the source data from the control module or other external source device to the receiving module of the corresponding box according to the connection information. The receiving module drives the LED display module to light up and display the corresponding image according to the received data.

[0052] When the sending module receives the screen connection command, it sends a lighting instruction to the receiving module connected to each network port in a preset order. When the receiving module receives the lighting instruction, it drives the LED display module in the box where it is located to light up and display the corresponding preset display content, including:

[0053] When the sending module receives the screen connection command, it sends a lighting instruction to the first receiving module connected to the first network port;

[0054] When the first receiving module receives the lighting instruction, it drives the LED display module in the first box where it is located to light up and display the first preset display content;

[0055] When the LED display module of the first box is lit, the sending module sends the next lighting instruction to the second receiving module connected to the first receiving module;

[0056] When the second receiving module receives the lighting instruction, it drives the LED display module in the second box where it is located to light up and display the second preset display content;

[0057] By analogy, the LED display modules of the boxes where all the receiving modules connected to the first network port are located are driven to light up and display the corresponding preset display content;

[0058] According to the above process, the LED display modules of the boxes where all receiving modules connected to the second network port, the third network port, ..., the Mth network port are located are driven in sequence according to the network port number to light up and display the corresponding preset display content; M is a natural number greater than or equal to 1.

[0059] Specifically, the sending module includes several network ports. For example, the number of network ports is M, where M is a natural number greater than or equal to 1. These network ports are marked as the first network port, the second network port, ..., the Mth network port. When the sending module receives the screen connection command from the control module, it first sends a lighting instruction to the first receiving module directly connected to the first network port, that is, the first receiving module. When the first receiving module receives the lighting instruction, Figure 4As shown, the LED display module of the box (recorded as the first box) where it is located is driven to light up and display the corresponding preset display content, which is recorded as the first preset display content. Preferably, the first preset display content includes the network port number and the lighting sequence number. For example, the first receiving module in the first box is connected to the first network port and is the first to be lit. The first preset display content can be "network port number: 1, lighting sequence number: 1", or "1-1" (where the first number represents the network port number, and the second number represents the lighting sequence number), or other characters or images that can be used to identify the network port information and the lighting sequence. When the first box is lit, the sending module continues to send the next lighting instruction to the second receiving module connected to the first receiving module. Similarly, after the second receiving module receives the lighting instruction, it drives the LED display module in the box (recorded as the second box) where it is located to light up and display the second preset display content. For example, the second preset display content can be "network port number: 1, lighting sequence number: 2", or "1-2", or other characters or images that can be used to identify the network port information and the lighting sequence. Similarly, after the second box is lit, the sending module continues to send the next lighting instruction to the third receiving module connected to the second receiving module. After receiving the lighting instruction, the third receiving module drives the LED display module in the third box where it is located to light up and display the third preset display content. Exemplarily, the third preset display content can be "network port number: 1, lighting number: 3", or "1-3", or other characters or images that can be used to identify network port information and lighting order... and so on. The sending module sends lighting instructions in turn and drives the LED display modules of the boxes where all receiving modules connected to the first network are located to light up and display the corresponding preset display contents. According to these preset display contents, the series connection order or connection order of all receiving modules connected to the first network port can be obtained.

[0060] In one embodiment, in order to more clearly highlight the lit cabinet, the control module keeps the LED display modules of all cabinets off, i.e., in a black screen state, before sending the screen connection command. When the sending module sends the lighting command to the first receiving module, only the first cabinet is lit, and the other cabinets are all black screens; and when the sending module sends the next lighting command to the second receiving module, the first cabinet is first turned off, and then the second cabinet is lit. Before the third cabinet is lit, the second cabinet is first turned off and then the third cabinet is lit... and so on, all cabinets connected to the first network port are lit in turn.

[0061] After the box connected to the first network port is lit up, according to the above process, the LED display modules of the boxes where all the receiving modules connected to the second network port, the third network port, ..., the Mth network port are located are driven to light up and display the corresponding preset display content in sequence according to the network port number. Figure 5As shown, a lighting instruction is sent to the first receiving module directly connected to the second network port, namely the N+1th receiving module (where N is the number of receiving modules connected in series with the first network port). When the N+1th receiving module receives the lighting instruction, it drives the LED display module of the box where it is located to light up and display the corresponding preset display content, and the preset display content can be "network port number: 2, lighting number: 5", or "2-5", or other characters or images that can be used to identify the network port information and the lighting order. When the N+1 box is lit, the sending module continues to send the next lighting instruction to the N+2 receiving module connected to the N+1 receiving module. Similarly, after the N+2 receiving module receives the lighting instruction, it drives the LED display module in the box where it is located to light up and display the corresponding preset display content, which is exemplarily "Network port number: 2, lighting number: 6", or "2-6", or other characters or images that can be used to identify network port information and lighting sequence... After all the boxes connected to the second network are lit, the series sequence or connection sequence of all receiving modules connected to the second network port is obtained. Similarly, the series sequence or connection sequence of all receiving modules connected to the third network port, ..., and the Mth network port is obtained, thereby obtaining the connection sequence of the receiving modules connected to each network port, that is, the connection information.

[0062] In order to intuitively obtain the connection information, preferably, the preset display content includes the network port number and the lighting sequence number. According to the network port number, the connection network port of the receiving module in each box can be intuitively determined, and according to the lighting sequence number, the connection order of the receiving modules connected to each network port can be intuitively obtained, so as to achieve what you see is what you get when obtaining the connection signal, which is simple and fast.

[0063] In one embodiment, the connection information of the LED display screen is obtained according to each of the preset display contents, and the connection information includes the connection network port of each of the boxes and the connection sequence includes:

[0064] Controlling the image acquisition device to acquire the preset display content displayed by the LED display modules in each box in the LED display screen, obtain the box lighting image and transmit it to the control module;

[0065] The control module is driven to perform image analysis processing according to the box lighting image to obtain the connection network ports and connection sequence in each of the boxes.

[0066] Specifically, by using an image acquisition device such as a camera to capture the lighting conditions of each box, including the lighting order of each box and the preset display content of the color display, the box lighting image or video is obtained, and these data are transmitted to the control module. The control module processes and analyzes the box lighting image or video and automatically obtains the connection information. It is worth pointing out that the preset display content here is not limited to the above-mentioned network port sequence number and lighting sequence number, and can also be any image or just light up all or any LED lights of the LED display module in the box. The image acquisition device records the lighting order of the box and obtains the network port currently connected to the lit box to obtain the connection information corresponding to each receiving module in the network port. The image acquisition device and the control module are used to automatically generate and save the connection information, which is convenient for subsequent maintenance and expansion, ensuring that the LED display screen system can quickly and accurately obtain the connection order of each box each time it is started or adjusted, and achieve a fast and accurate screen display effect.

[0067] After the control module obtains the connection information, it sends the connection information to the sending device, and the sending device sends corresponding data to the receiving modules in each box according to the connection information, thereby realizing the continuous screen playback of the LED display screen.

[0068] In summary, the method for obtaining the connection information of the LED display screen provided by the embodiment of the present invention first assembles multiple boxes into an LED display screen, and connects the sending module and the receiving module in each box through the network port. After the control module sends the screen connection command, the sending module sends the lighting instruction to the receiving module in a preset order to drive the LED display module in the box to light up and display the preset display content, and obtains the connection information of the LED display screen according to the preset display content. In this way, the connection status of each box can be intuitively obtained, and the connection network port and connection sequence of the receiving module can be confirmed. The method can quickly obtain the connection relationship of the receiving modules in each box in the LED display screen, simplify the debugging process, reduce the dependence on the skills of the construction personnel, and greatly reduce the time and cost of debugging. Furthermore, the connection information can be automatically generated and saved by using the image acquisition device and the control module, which is convenient for subsequent maintenance and expansion, ensuring that the LED display screen system can quickly and accurately obtain the connection sequence of each box each time it is started or adjusted, and achieve a fast and accurate screen connection display effect.
