[0002] LED display screens are widely used in various indoor and outdoor occasions due to their advantages of high brightness, wide color gamut, and flexible splicing. In order to use LED display screens, many supporting equipment are also required, such as video processing equipment, sending cards, receiving cards, etc. In medium and large-scale activities, these devices have strong performance and large numbers. Some of them have dozens of interfaces, and the total number of interfaces and connecting lines is as high as hundreds.

[0080] It should be understood that the size of the serial numbers of the steps in this embodiment does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0081] In the related art, in order to configure the equipment, operators often need to spend a lot of time to check and understand the connection relationship between each device, and configure while observing; or even configure according to guesswork first, and then infer the actual connection according to the wrong display image. Such configuration work is extremely difficult and requires experienced operators to spend a lot of time to complete. It is not only inefficient and unreliable, but also has high labor costs.

[0082] In view of this, the embodiment of the present application provides a method, system and device for generating topological information of an LED display control system, wherein each first node device sends and receives identification information to a second node device set, collects identification information of each node device, and finally summarizes the target identification information and sends it to the control device, thereby generating a topological map. The topological map can intuitively locate the wrong connection between each node device, and the embodiment of the present application can be automatically implemented throughout the process, without the need for operators to spend a lot of time on-site inspection, reducing the difficulty of node device configuration, thereby not only saving labor costs and time costs, but also improving the efficiency and accuracy of device configuration.

[0083] In order to illustrate the technical solution of the present application, specific embodiments are provided below.

[0084] See also Figure 1 , shows a schematic diagram of the structure of an LED display control system provided in Example 1 of the present application. Figure 1 As shown, the LED display control system includes a control device and at least one node device, the node device includes a first node device, and the first node device refers to a node device connected to the control device.

[0085] Among them, the control device can be a device with an embedded operating system (such as Windows operating system, Android, etc.), a device that can process data and issue operation commands, such as a PC, an industrial computer, a workstation, a touch screen computer, etc. In the LED display control system, the control device can be a splicer, a switcher, a console, a controller, a media server, a video processing device, a sending card, a receiving card, etc. The control device can realize the data display and viewing function of the node device through the screen. The control device stores the number of node devices in the LED display control system, as well as the device type, device unique identifier, interface number, interface identifier, and interface type of each node device.

[0086] Each node device is provided with at least one interface for transmitting video signals. In order to configure each node device, it is necessary to obtain the connection relationship between all node devices and the working information of each interface.

[0087] In the embodiment of the present application, the first node device refers to a node device directly connected to the control device in the LED display control system, the second node device refers to a downstream device connected to the first node device, and all second node devices in the LED display control system constitute a second node device set.

[0088] See also Figure 2 , which is a signaling interaction diagram between the control device and the first node device in the LED display control system provided in an embodiment of the present application.

[0089] like Figure 2 As shown, the LED display control system can be used to perform the following steps:

[0090] Step 201: A control device sends a target identification information acquisition instruction to at least one first node device.

[0091] In an embodiment of the present application, the operator can, based on the actual situation on site, when it is necessary to understand the topology diagram of the current LED display control system, issue a target identification information acquisition instruction to the first node device through the human-computer interaction device mounted on the control device, such as a touch screen, command button, etc.

[0092] As a possible implementation method, since the topology information between each node device may change at regular intervals, the control device can automatically send target identification information acquisition instructions at regular intervals to regularly generate a topology map and display it to the on-site operator.

[0093] Step 202: The first node device forwards the first identification information corresponding to the first node device to the second node device set, and obtains the second identification information from the second node device set.

[0094] The second node device set includes at least one second node device.

[0095] It should be understood that when the first node device obtains the target identification information acquisition instruction sent by the control device, it can start to send the first identification information to each second node device connected to it, and the second node device can also send the identification information corresponding to the second node device to its corresponding downstream device, and forward the identification information to the downstream device in turn. Correspondingly, when the first node device sends the first identification information to the second node device connected to it, the downstream device of the first node device can also send the second identification information to the first node device in the above manner. The forwarding and return of the transmission of identification information can be realized in the above manner.

[0096] In a possible embodiment, when the identification information of each node device in the LED display control system is just being collected, if a first node device has not yet received the identification information sent by other node devices, the first identification information corresponding to the first node device may be the tag information corresponding to the first node device itself. The tag information corresponding to each node device is different, wherein the tag information may be information used to indicate the connection relationship between the node devices.

[0097] For example, the tag information may be a unique device identifier corresponding to a node device and an interface identifier corresponding to an interface. For example, when a first node device R sends first identification information to a second node device connected thereto through interface a, the first identification information includes: unique device identifier R and interface a.

[0098] As a possible implementation method, the tag information may also include the device type, device status, interface type, interface status, and other information that can be used for topology information detection of the node device, and this application does not limit this. In actual use, the type of tag information that needs to be collected when generating the system topology map can be determined according to actual needs and specific application scenarios.

[0099] In another possible embodiment, when collecting identification information of each node device in the LED display control system, if a first node device has already received the identification information sent by the second node device before sending the first identification information to the second node device set, the first node device can merge its corresponding tag information with the acquired second identification information to generate new first identification information and forward it to the second node device set.

[0100] For example, the first node device obtains the second identification information from the second node device set. For example, the interface b of the first node device S receives the second identification information, where the second identification information includes the device unique identifier T and the interface identifier c. At this time, the first node device S can determine that its interface b is connected to the interface c of the second node device T, so that the first node device S can merge the first identification information and the second identification information of the second node device T according to the connection relationship to generate the first identification information forwarded to other node devices.

[0101] As a possible implementation method, since each node device may store a large amount of the same identification information as other node devices after a period of time after receiving the target identification information acquisition instruction, in order to avoid data redundancy, each node device can deduplicate the same tag information before forwarding it next time, so as to further improve the efficiency and reliability of topology map generation.

[0102] Step 203: The first node device merges the first identification information with the second identification information to generate target identification information.

[0103] In the embodiment of the present application, since the control device is generally not connected to all the node devices, in order to enable the control device to know the topology information between all the node devices, each first node device in the system needs to forward and recycle the identification information corresponding to each node device in the system, so that the control device can obtain the identification information of each node device in the entire system through each first node device. Therefore, after receiving the second identification information, the first node device needs to merge the first identification information with the second identification information to generate the target identification information sent to the control device.

[0104] It should be noted that the method of fusing and generating target identification information is the same as the method in which the first node device fuses and generates new first identification information and forwards it to the second node device set in the above step 202. The specific implementation process and principle can refer to the detailed description of the above steps and will not be repeated here.

[0105] Step 204: The first node device sends the target identification information to the control device.

[0106] In an embodiment of the present application, when the first node device generates target identification information, the target identification information can be sent to the control device, so that the identification information of the second node device that is not connected to the control device can also be forwarded by the first node device and finally summarized to the control device, thereby realizing the collection of identification information of each node device in the entire system.

[0107] Step 205: The control device parses and integrates the target identification information to generate a topology diagram of the LED display control system.

[0108] In an embodiment of the present application, the control device can obtain the connection relationship between each node device accurate to the interface level through target identification information, so that the topology information of all node devices in the LED display control system can be easily analyzed and displayed to the operator in the form of a graphical topology diagram, so that the operator can fully grasp the connection information of the node device and the working information of each interface, and can easily complete the configuration work.

[0109] It should be understood that when the control device receives the target identification information sent by the first node device, the control device can determine the connection relationship between each first node device and the control device, that is, the topology map of the LED display control system finally generated not only includes the topology information between all node devices, but also includes the topology information between the control device and the first node device.

[0110] The LED display control system disclosed in the above embodiment of the present application includes a control device and at least one node device. The control device sends a target identification information acquisition instruction to the first node device, the first node device forwards the first identification information to the second node device set, and obtains the second identification information from the second node device set, fuses and generates target identification information and sends it to the control device, and the control device parses and integrates the target identification information to generate a topological map of the LED display control system. Thus, by sending and receiving identification information to the second node device set by each first node device, the identification information of each node device is collected, and finally the target identification information is summarized and sent to the control device, thereby generating a topological map. Through the topological map, the wrong connection between each node device can be intuitively located. At the same time, the embodiment of the present application can be automatically realized throughout the process, without the need for operators to spend a lot of time on-site inspection, reducing the difficulty of node device configuration, thereby not only saving labor costs and time costs, but also improving the efficiency and accuracy of device configuration.

[0111] See also Figure 3 , is a flow chart of a method for generating topology information provided in Embodiment 2 of the present application, and the method for generating topology information is applied to Figure 1 At least one first node device in the LED display control system shown. Figure 3 As shown, the topology information generation method includes:

[0112] Step 301: Receive a target identification information acquisition instruction sent by a control device.

[0113] Step 302: forward the first identification information corresponding to the first node device to the second node device set, and obtain the second identification information from the second node device set.

[0114] The second node device set includes at least one second node device, and the second node device refers to a downstream device connected to the first node device.

[0115] Furthermore, in the LED display control system, video data is usually exchanged between the node devices, so the video data can be used as a medium to realize the sending and returning of identification information, that is, in a possible implementation method of the embodiment of the present application, the above step 302 may include:

[0116] Forwarding the video data including the first identification information to the second node device set;

[0117] The video data including the second identification information forwarded by the second node device set is received, and the video data is analyzed and processed to determine the second identification information.

[0118] Specifically, when the first node device transmits video data, it can send the first identification information to the second node device connected to it through the video data, and the second node device then sends the identification information to the downstream device in the same way, and the downstream device sends the identification information back in reverse until the first node device parses the video data received from the second node device connected to it and obtains the second identification information. In this way, the second node device that is not directly connected to the control device in the LED display control system can also forward the corresponding identification information in sequence by sending video data until it is forwarded to the first node device, so that the identification information of all node devices is finally forwarded to the control device through the first node device for aggregation.

[0119] In an embodiment of the present application, the identification information can be transmitted in the frame interval of the video data, or by inserting a frame of image containing the identification information into the video data for transmission, or by inserting the identification information into any image frame in the video data for transmission, etc.

[0120] The following describes three possible ways of transmitting identification information.

[0121] As a first possible implementation method of transmitting identification information according to an embodiment of the present application, the identification information may be transmitted in a frame interval of video data.

[0122] Among them, in order not to affect the normal image display, for node devices connected by video signals such as HDMI, DP, SDI, DVI, etc., frame intervals can be used to transmit identification information. General digital video signals are composed of a certain number of static images per second. This number is the frame rate. For example, movie images are generally 24 frames / second, that is, 24 frames per second, and computer displays are 60 frames / second, that is, 60 frames per second. Often, the transmission of these images cannot 100% utilize the bandwidth of the transmission link. Therefore, after transmitting a frame of image, it is necessary to wait for a certain period of time before transmitting the next frame of image. This waiting time is the frame interval. Under the premise of not affecting the normal image display, these frame intervals can be used to transmit identification information. That is, in a possible implementation method of the present application, the above-mentioned forwarding of video data containing the first identification information to the second node device set may include:

[0123] Get the transmission frame rate and single frame transmission time of the sent video data;

[0124] Determine the time interval between adjacent frames corresponding to the video data according to the transmission frame rate;

[0125] Determining a frame interval in each adjacent frame time interval according to a single frame transmission time;

[0126] The first identification information is forwarded to the second node device set within the frame interval.

[0127] Correspondingly, the above-mentioned receiving the video data including the second identification information forwarded by the second node device set, parsing and processing the video data, and determining the second identification information may include:

[0128] The second identification information forwarded by each second node device within the frame interval is received.

[0129] In the embodiment of the present application, firstly, the adjacent frame time interval corresponding to the video data is determined according to the transmission frame rate of the video data sent by the first node device. For example, if the first node device sends the video data at a transmission frame rate of 60 frames / second, then the interval time of each frame of the video data, that is, the adjacent frame time interval is 1 second / 60=16.7 milliseconds. Then, the frame interval can be obtained by combining the adjacent frame time interval and the single frame transmission time of the video data. For example, the time required to transmit a frame of image, that is, the single frame transmission time is 10 milliseconds, then there is 6.7 milliseconds between every two frames in the video data that can be used to send the first identification information.

[0130] Correspondingly, when the first node device sends the first identification information to the second node device connected to it in the frame interval of the video data, each second node device corresponding to the first node device can also use the same method to forward the identification information to the first node device in sequence. It should be understood that the second node device connected to the first node device can send identification information to the first node device in the frame interval of the video data, and the second node device not connected to the first node device can use the same method to forward the identification information to the first node device in sequence. Therefore, in order to extract the second identification information of the second node device set, the first node device needs to receive the second identification information corresponding to the second node device set within the frame interval of the second node device connected to the first node device sending the video data.

[0131] Exemplarily, the HDMI OUT 1 interface of the video processing device is connected to the HDMI IN 1 interface of the sending card, and sends video data at 60 frames per second. Then the video processing device can repeatedly send the second identification information at the frame interval. The sending card receives the second identification information within the frame interval of the video data and parses it. The parsed second identification information is "device sn:2741840; type:video processor; status:ok; interface id:hdmi out 1; interface type:hdmi; interface status:ok", that is, the second identification information of the video processing device is: the device unique identifier is 2741840, the device type is a video processing device, the device status is normal, the interface identifier is HDMI OUT 1, the interface type is HDMI, and the interface status is normal. It can be seen that the HDMI IN 1 interface of the sending card is connected to the HDMI OUT 1 interface of the video processing device.

[0132] Therefore, by transmitting identification information in the frame interval of video data, the topology information between each node device can be determined without affecting the normal image display, thereby generating a topology map.

[0133] As a second possible implementation method for transmitting identification information in an embodiment of the present application, the identification information may be transmitted by inserting a frame of image containing the identification information into the video data for transmission.

[0134] Among them, for node devices that cannot use frame intervals, the output interface of the node device can output a specified image signal containing characteristic information according to the preset rules issued by the control device, wherein the preset rules can be a predetermined program pre-set by the control device. The image can be inserted into the original video data for transmission, or the transmission of the original video can be stopped and only the image signal containing the characteristic information can be transmitted. The selection is made according to actual needs, and this application does not limit this. That is, in a possible implementation of the present application, the above-mentioned sending of video data containing the first identification information to the second node device set can include:

[0135] Encode the first identification information according to a preset rule issued by the control device to generate an image containing the first identification information;

[0136] Inserting the image including the first identification information into the video data to generate the video data including the first identification information;

[0137] The video data including the first identification information is forwarded to the second node device set.

[0138] Correspondingly, the above-mentioned receiving the video data including the second identification information forwarded by the second node device set, parsing and processing the video data, and determining the second identification information may include:

[0139] receiving video data including second identification information forwarded by the second node device set;

[0140] Analyze and process the video data containing the second identification information to determine the image containing the second identification information;

[0141] According to a preset rule, the image containing the second identification information is parsed to determine the second identification information corresponding to the second node device set.

[0142] In the embodiment of the present application, for the first node device that cannot use the frame interval, a frame of image containing the first identification information can be inserted into the normal display video for transmission. The second node device also stores a preset rule, and the image containing the first identification information and the first identification information should meet the preset rule issued by the control device, so that the subsequent second node device can parse the corresponding first identification information through the preset rule. It should be understood that any node device can use the above method to forward the identification information to the downstream device.

[0143] Correspondingly, when the first node device forwards the video data containing the first identification information to the second node device set, the second node device set corresponding to the first node device can also forward the second identification information to the first node device in the same manner. That is, after receiving the video data containing the second identification information sent by each second node device connected to it, the first node device can parse and process the video data containing the second identification information to obtain an image containing the second identification information, so that the first node device can parse the second identification information according to the preset rules. It should be understood that any node device can parse the identification information returned by the downstream device in the above manner.

[0144] In the embodiment of the present application, the identification information may be in the form of a certain amount of different information, which may be any one of color, graphics, and display position.

[0145] As a possible implementation, the second identification information in the image may be in the form of different colors. For example, an image with an 8-bit bit depth has 256*256*256=16,777,216 different colors. Each color may correspond to a certain interface of a second node device according to a preset rule, so that the first node device can parse the second identification information corresponding to the image according to the color of the image containing the second identification information. Further, the second identification information in the image may also be in the form of a unique color of each pixel in the image. Exemplarily, the device unique identifier of the second node device is 123, and the second node device 123 is connected to the first node device via interface d. The preset rule may be that the image includes 4 corresponding pixels at specific positions, of which three pixels correspond to the device unique identifier, and red represents 1, green represents 2, and blue represents 3, and another pixel corresponds to the interface identifier, and yellow represents interface d. In this way, the red pixel, green pixel, or blue pixel in the image may be used to represent the device unique identifier 123 corresponding to the second node device, and the yellow pixel in the image may be used to represent the interface identifier corresponding to the second node device as interface d.

[0146] As another possible implementation, the identification information in the image may be in the form of a certain number of different geometric figures, or in the form of a uniform geometric figure appearing at different positions on the image. Geometric figures of different shapes or at different positions may also be used to represent the identification information corresponding to the node device. The preset rules can be found in the description of the colors above, which will not be repeated here.

[0147] As another possible implementation, in order not to affect the display of normal images, the identification information may also be in a small size, transparent, or encoded in the normal display image (not easily identifiable by naked eyes).

[0148] Therefore, a frame of image containing identification information can be inserted into the video data to transmit the identification information, so as to obtain the identification information corresponding to the node device that cannot use the frame interval.

[0149] As a third possible implementation method for transmitting identification information according to an embodiment of the present application, the identification information may be transmitted by inserting the identification information into any image frame in the video data for transmission.

[0150] The identification information may also be transmitted together with the normally displayed image. An image frame may be selected in the video data, and the identification information may be stored in the image frame. In order not to affect the normal image display, the data space occupied by the identification information in the image should be as small as possible. That is, in a possible implementation of the present application, the video data containing the first identification information is forwarded to the second node device, including:

[0151] Get the image resolution corresponding to any image frame in the video data;

[0152] Scaling the image resolution to determine a data space for storing the first identification information;

[0153] storing the first identification information in the data space, and generating video data including the first identification information;

[0154] The video data including the first identification information is forwarded to the second node device.

[0155] Correspondingly, the receiving of the video data including the second identification information forwarded by the second node device, and parsing and processing the video data to determine the second identification information includes:

[0156] receiving video data including second identification information forwarded by the second node device set;

[0157] Analyze and process the video data containing the second identification information to determine any image frame in the video containing the second identification information;

[0158] The second identification information is obtained from any image frame.

[0159] In an embodiment of the present application, the identification information of any node device can be transmitted together with the normally displayed image. Any frame of the video data can be scaled, and then the identification information can be stored in the scaled data control space. For example, if the image resolution corresponding to any frame of the video data is 1920*1080, scaling the image to 1919*1080 can obtain a 1*1080 data space that can be used to store the identification information.

[0160] In the embodiment of the present application, after each node device parses and processes the video data to obtain identification information, it is necessary to readjust the image resolution of the scaled image to the original image resolution for display.

[0161] Therefore, only a small part of the data space in a frame of the original video data is used to transmit the identification information, which hardly interferes with the normal image display of each node device.

[0162] Step 303: merge the first identification information and the second identification information to generate target identification information.

[0163] As a possible implementation manner, the target identification information includes tag information corresponding to each node device, and the tag information includes a unique device identifier and an interface identifier of the node device.

[0164] Step 304, sending the target identification information to the control device, so that the control device parses and integrates the target identification information to generate a topology diagram of the LED display control system.

[0165] For some other specific implementation processes and principles in the embodiments of the present application, reference can be made to the detailed description of the above embodiments and will not be repeated here.

[0166] The topology information generation method disclosed in the above embodiment of the present application is that the first node device first receives the target identification information acquisition instruction sent by the control device, and then forwards the first identification information corresponding to the first node device to the second node device set, and obtains the second identification information from the second node device set, further merges the first identification information with the second identification information, generates the target identification information, and finally sends the target identification information to the control device, so that the control device parses and integrates the target identification information to generate a topology map of the LED display control system. Thus, by sending and receiving identification information to the second node device set by each first node device, the identification information of each node device is collected, and finally the target identification information is summarized and sent to the control device, thereby generating a topology map. Through the topology map, the wrong connection between each node device can be intuitively located. At the same time, the embodiment of the present application can be automatically realized throughout the process, without the operator spending a lot of time on-site inspection, reducing the difficulty of node device configuration, thereby not only saving labor costs and time costs, but also improving the efficiency and accuracy of device configuration.

[0167] See also Figure 4 , is a flow chart of a method for generating topology information provided in Example 3 of the present application, and the method for generating topology information is applied to Figure 1 The control device in the LED display control system shown in the figure. Figure 4 As shown, the topology information generation method includes:

[0168] Step 401: Send a target identification information acquisition instruction to at least one first node device.

[0169] The first node device refers to a node device connected to the control device;

[0170] Step 402: Receive target identification information sent by each first node device.

[0171] The target identification information includes identification information forwarded by each first node device to the second node device set and obtained from the second node device set. The second node device set includes at least one second node device, and the second node device refers to a downstream device connected to the first node device.

[0172] In an embodiment of the present application, the target identification information includes tag information corresponding to each node device, and the tag information may include a unique device identifier and an interface identifier of the node device.

[0173] Step 403, parse and integrate the target identification information to generate a topology diagram of the LED display control system.

[0174] The topology information generation method disclosed in the above-mentioned embodiment of the present application is that the control device sends a target identification information acquisition instruction to at least one first node device, then receives the target identification information sent by each first node device, and finally parses and integrates the target identification information to generate a topology map of the LED display control system. Thus, by receiving the target identification information sent by each first node device, the collection of identification information of each node device is realized, and finally the target identification information is summarized and sent to the control device, thereby generating a topology map. Through the topology map, the wrong connection between each node device can be intuitively located. At the same time, the embodiment of the present application can be automatically implemented throughout the process, without the need for operators to spend a lot of time on-site inspection, reducing the difficulty of node device configuration, thereby not only saving labor costs and time costs, but also improving the efficiency and accuracy of device configuration.

[0175] Furthermore, the control device stores the total number of node devices in the LED display control system. When the number of node devices involved in the target identification information received by the control device reaches a preset number, that is, the total number of node devices pre-stored by the control device, it indicates that the control device has received the identification information of all node devices. At this time, all identification information can be integrated to generate a topology map. That is, in a possible implementation of the embodiment of the present application, the above step 403 may include:

[0176] Analyze and process each received target identification information to determine the node device involved in each target identification information;

[0177] When the number of node devices involved in each target identification information reaches a preset number, the target identification information is integrated to generate a topology diagram of the LED display control system.

[0178] In the embodiment of the present application, since the control device needs to integrate the topology information between all node devices included in the entire LED display control system, the control device needs to obtain the connection relationship between all node devices in the LED display control system, so before the control device generates a topology map, the control device needs to determine whether the identification information corresponding to all node devices has been obtained. Therefore, when the number of node devices involved in the target identification information reaches a preset number, the control device can determine that the identification information of all node devices in the LED display control system has been obtained, thereby obtaining the connection relationship between all node devices and generating a topology map.
