Technical Field

[0002] Currently, to achieve a large-screen display effect, the agent management system can connect to a large-size display screen (or simply a large screen). The agent management system can send the signals that need to be displayed (such as video) to the large screen for display.

[0003] However, when the large screen connected to the seat management system is a light-emitting diode (LED) display, the seat management system cannot directly drive the LED display for display. It requires the use of an LED transmitting card. The main function of the LED transmitting card is to convert and process the signals transmitted from the seat management system to meet the display requirements of the LED display, thereby enabling the LED display to display normally.

[0004] In the above solution, the seat management system first connects to the LED sending card, and the LED sending card then connects to the LED display screen, resulting in complex wiring. Complex wiring is prone to issues such as loose cables and poor contact, thus reducing the stability of the large-screen display. Utility Model Content

Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings: Figure 1 This diagram illustrates the structure of a seat management system provided by related technologies. Figure 2 This paper shows a schematic diagram of the structure of a seat management system provided in an embodiment of the present application; Figure 3 A flowchart illustrating a large-screen display method for a seat management scenario provided in an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of a seat management system provided in an embodiment of this application is shown. Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0024] To more clearly illustrate the embodiments of this application, the technical terms used in the embodiments of this application will be briefly introduced below: (1) Seat Management: This is the process of comprehensively managing and scheduling the operator seats (referred to as seats) and their corresponding equipment, signals, and permissions in scenarios such as command centers and monitoring centers. Specifically, it covers the addition and removal of seats, the association settings between seat devices and remote devices, the setting of operating permissions for seat devices (such as setting viewing permissions and control permissions), and the switching and sharing of signals between seat devices. Its core objective is to optimize the allocation of seat resources and ensure the orderly and efficient management and control process.

[0025] Optionally, the agent device may include a keyboard and a mouse.

[0026] Alternatively, the remote device may be a computer or a server, etc.

[0027] (2) KVM: It is an abbreviation for Keyboard, Video, and Mouse. It is a technology that allows agents to remotely control and operate multiple remote devices using a single keyboard, mouse, and monitor. KVM technology is a key technology for realizing agent management.

[0028] (3) Seat Management System: This is a specialized technical platform for realizing seat management functions. The fiber optic seat management system is a typical example of a seat management system. Based on fiber optic transmission technology, it does not rely on the Internet Protocol (IP) network and can centrally manage multiple seat devices and their signals, realizing real-time signal transmission, switching, and distribution. With the advantages of high bandwidth, low latency, and strong anti-interference of fiber optics, the fiber optic seat management system is suitable for scenarios with extremely high requirements for signal quality and response speed. It can also integrate functions such as large-screen splicing display, providing technical support and implementation carrier for seat management.

[0029] Alternatively, the fiber optic agent management system may be referred to as a fiber optic non-IP agent management system.

[0030] In addition to providing agent management functions, the fiber optic agent management system can also be expanded to include signal processing and large-screen display functions. The large-screen display function refers to the fiber optic agent management system connecting to a large display screen (i.e., a large screen) and transmitting multiple signals (e.g., signals from agent devices and remote devices) to the large screen for display. For example, the large screen can be an LED display, LCD, or OLED.

[0031] However, when the large screen is an LED display, the fiber optic workstation management system cannot directly drive the LED display; it requires the use of an LED transmitting card. The main function of the LED transmitting card is to convert and process the signals transmitted from the fiber optic workstation management system to meet the display requirements of the LED display, thus enabling normal display. The fiber optic workstation management system connects to the LED transmitting card, which then connects to the LED display, resulting in complex wiring. This complex wiring is prone to loose cables and poor contact, reducing the stability of the large screen display.

[0032] In addition, the LED sending card is equipped with a dedicated control terminal (or LED control terminal). This terminal provides system configuration functions such as debugging the display characteristics and topology connections of the LED display. The seat management system lacks the capability to configure the LED display. This necessitates operating the LED control terminal, separate from the fiber optic seat management system, to configure the LED display in a seat management scenario. In other words, users must operate both the fiber optic seat management system and the LED control terminal separately to control the LED display's display and system configuration. This process is inefficient and prone to asynchronous operations between the two systems, significantly reducing the efficiency of configuring the large screen in a seat management scenario.

[0033] Reference Figure 1 This is a structural diagram of a seat management system provided for related technologies. For example... Figure 1 As shown, the seat management system 100 provided by related technologies may include: a seat management host 110, an optical fiber transmitting node 121, an optical fiber receiving node 122, a system control device 130, seat devices 140, and a remote device 150. The seat management host 110 may include: a main control card 111, an optical fiber input card 112, an optical fiber output card 113, a video input card 114, and a video output card 115, etc.

[0034] The main control card 111 is connected to the system control device 130 via a communication line, and is also connected to the fiber optic input card 112, fiber optic output card 113, video input card 114, and video output card 115. The fiber optic input card 112 is connected to the fiber optic transmitting node 121 via fiber optic cable, and the fiber optic transmitting node 121 can connect to multiple remote devices 150 via a KVM transmission line. The fiber optic output card 113 is connected to the fiber optic receiving node 122 via fiber optic cable, and the fiber optic receiving node 122 can connect to multiple workstation devices 140 via a KVM transmission line. The video input card 114 is connected to a local video source via an audio / video transmission line. The video output card 115 is connected to the LED transmitting card 160 via a communication line, and the LED transmitting card 160 is connected to the LED control terminal 170 via a communication line. The LED transmitting card 160 is also connected to the LED display screen 180 via a communication line.

[0035] The main control card 111 is the core control unit of the seat management host 110. It is used to receive and respond to the control signals input by the administrator in the system control device 130, and control the fiber optic input card 112, fiber optic output card 113, video input card 114 and video output card 115 in the seat management host 110, so as to realize the comprehensive management and scheduling of the seat device 140 and its signals and permissions.

[0036] The fiber optic input card 112 is used to send control signals from the agent device 140 to the remote device 150 via the fiber optic transmitting node 121. The remote device 150 can generate response information in response to the control signals from the agent device 140.

[0037] The fiber optic output card 113 is used to receive control signals input by the operator on the agent device 140 through the fiber optic receiving node 122, and can also send response information generated by the remote device 150 to the agent device 140 through the fiber optic receiving node 122.

[0038] Video input card 114 is used to acquire video from a local video source. Video output card 115 is used to send signals (e.g., audio and video) to an external display (e.g., LED display 180).

[0039] The process by which the seat management system 100 controls the display of the LED display screen 180 may include: the main control card 111 can acquire the target video from the fiber optic input card 112 or the video input card 114; then, the video output card 115 sends the target video to the LED sending card 160; the LED sending card 160 converts and processes the target video to obtain the processed video, and then sends the processed video to the LED display screen 180.

[0040] To address the aforementioned problems in related technologies, this application proposes a large-screen display method for a seat management scenario, applied to a seat management system. The seat management system includes a main control unit and an LED control unit. The main control unit is used for comprehensive management and scheduling of the seat management system. The LED control unit is used to convert and process the target video sent by the main control unit to obtain a processed video that meets the display requirements of the LED display screen, and to send the processed video to the LED display screen.

[0041] In this embodiment, the seat management system can directly drive the LED display screen for display through the LED control unit. This design simplifies the connection lines between the seat management system and the LED display screen, thereby reducing the possibility of loose cables and poor contact, and improving the stability of the large screen display.

[0042] Please refer to Figure 2 This is a schematic diagram of a seat management system provided in an embodiment of this application. Figure 2 As shown, the agent management system 200 includes an agent management host 210, an optical fiber transmitting node 221, an optical fiber receiving node 222, a system control device 230, agent devices 240, and a remote device 250. The agent management host 210 may include a main control unit 211, an optical fiber input unit 212, an optical fiber output unit 213, a video input unit 214, and an LED control unit 215, etc.

[0043] The main control unit 211 is connected to the system control device 230 via a communication line, and is also connected to the fiber optic input unit 212, fiber optic output unit 213, video input unit 214, and LED control unit 215.

Specifically, it covers the addition and removal of seat devices 240, the association settings between seat devices 240 and remote devices 250, the setting of operation permissions for seat devices 240 (such as setting viewing permissions and control permissions), and the switching and sharing of signals between seat devices 240.

[0045] The system control device 230 is used to receive and respond to control signals input by the administrator, and to control the main control unit 211. The system control device 230 may include system control software.

[0046] The LED control unit 215 is used to process the video sent by the main control unit 211 based on the display requirements of the LED display screen, obtain the processed video, and then send the processed video to the LED display screen.

[0047] The fiber optic input unit 212 is used to send control signals from the agent device 240 to the remote device 250 via the fiber optic transmitting node 221. The remote device 250 can generate response information in response to the control signals from the agent device 240.

[0048] The fiber optic output unit 213 is used to receive control signals input by the operator on the operator device 240 through the fiber optic receiving node 222, and can also send response information generated by the remote device 250 to the operator device 240 through the fiber optic receiving node 222.

[0049] The video input unit 214 is used to acquire video from at least one type of video source.

[0050] Alternatively, the communication line may include fiber optic cable, network cable, serial cable, universal serial bus (USB) and high-definition multimedia interface (HDMI) cable, etc.

[0051] Optionally, the LED control unit 215 includes a video processing unit and a video sending unit; wherein, the video processing unit is used to process the video sent by the main control unit 211 based on the display requirements of the LED display screen to obtain the processed video; the video sending unit is used to send the processed video to the LED display screen. The main control unit 211 is connected to the video processing unit via a communication line; the video sending unit and the video processing unit are connected to the LED display screen.

[0052] Optionally, the system control device 230 can be an operating terminal capable of receiving and processing control signals, such as a personal computer (PC), laptop computer, or tablet computer. The system control device 230 can be connected to the main control unit 211 via a network cable, serial cable, or USB cable.

[0053] Optionally, a seat device 240 may include a keyboard, mouse, and seat monitor, etc. A remote device 250 may include a server or computer. The seat device 240 can operate and control at least one remote device 250. The control permissions of the seat device 240 over the remote device 250 can be set by the system control device 230.

[0054] Optionally, both the fiber optic receiving node 222 and the fiber optic transmitting node 221 can be a signal transceiver.

[0055] Optionally, the various units within the seat management host 210 (including the main control unit 211, fiber optic input unit 212, fiber optic output unit 213, video input unit 214, and LED control unit 215) can be connected via at least one of the following switching methods: crosspoint switch, field-programmable gate array (FPGA), and switch.

[0056] This application provides a large-screen display method for a seat management scenario, which can be applied to the aforementioned seat management system 200. For example... Figure 3 As shown, the test method may include S301-S303.

[0057] S301, the seat device 240 receives a first control command input by the user, the first control command being used to instruct the display of a first video on the LED display screen.

[0058] A user (e.g., an agent) can input a first control command into an agent device 240 by operating a mouse and / or keyboard. The agent device 240 can then send the first control command to an optical fiber output unit 213 via an optical fiber receiving node 222. The optical fiber output unit 213 then forwards the first control command to the main control unit 211.

[0059] S302, the seat management host 210 responds to the first control command, acquires the first video, and sends the first video to the LED control unit 215.

[0060] The main control unit 211 in the seat management host 210 can respond to the first control command and acquire the first video from the fiber optic input unit 212 or the video input unit 214. The main control unit 211 then sends the first video to the LED control unit 215.

[0061] S303 and LED control unit 215 perform video processing on the first video based on the display requirements of the LED display screen to obtain the processed first video, and then send the processed first video to the LED display screen.

[0062] In some embodiments, video processing may include at least one of the following: format conversion, color adjustment, and video stitching.

[0063] In some embodiments, the operator device 240, in addition to receiving and processing control commands input by operators for remote devices 250 and control commands for display control of the LED display screen, can also be used to receive and process control commands for system configuration of the LED display screen.

[0064] Specifically, the process of configuring the LED display screen by the seat device 240 may include: the seat device 240 receiving a second control command input by the user, the second control command being used to instruct the LED display screen to perform system configuration; the seat management host 210 parsing and processing the second control command based on the command requirements of the LED display screen to obtain a third control command, and sending the third control command to the LED control unit 215; the LED control unit 215 sending the third control command to the LED display screen so that the LED display screen responds to the third control command to perform system configuration.

[0065] The instruction requirements of an LED display screen refer to the requirements of the LED display screen for instructions from other devices outside the LED display screen, which may include requirements for instruction format, instruction content, and transmission rate. When the instructions from other devices outside the LED display screen meet the instruction requirements of the LED display screen, the LED display screen can correctly identify, parse, and execute the instructions from those devices.

[0066] For example, the LED control unit 215 can send a third control command to the LED display's receiving card. The command request of the LED display can refer to the LED display's receiving card's request for a command from another device other than the LED display.

[0067] In some embodiments, the system control device 230, in addition to controlling the main control unit 211, can also be used to receive and process control commands for system configuration of the LED display screen. Specifically, the process of system configuration of the LED display screen by the system control device 230 may include: the system control device 230 receiving a fourth control command input by the user, the fourth control command being used to instruct system configuration of the LED display screen; the workstation management host 210 parsing and processing the fourth control command based on the command requirements of the LED display screen to obtain a fifth control command, and sending the fifth control command to the LED control unit 215; the LED control unit 215 sending the fifth control command to the LED display screen so that the LED display screen responds to the fifth control command to perform system configuration.

[0068] Optionally, the system configuration of the LED display screen by the system control device 230 includes at least one of the following: setting the display characteristics of the LED display screen and setting the topological connection relationship of the LED display screen. The display characteristics of the LED display screen may include the brightness and color of the LED display screen.

[0069] In some embodiments, in addition to receiving and responding to the first permission control instruction input by the administrator to set the operation permissions (such as viewing permissions and control permissions) of the seat device 240 to the remote device 250, the system control device 230 can also receive and respond to the second permission control instruction input by the administrator to set the system configuration permissions of the seat device 240 to the LED display screen, for example, granting the seat device 240 permissions to certain items in the system configuration of the LED display screen.

[0070] In other words, whether the seat device 240 can receive and process control commands for system configuration of the LED display screen is controlled by the system control device 230.

[0071] It is understood that in this embodiment, an LED control unit 215 integrating video processing and video transmission is added to the seat management system 200. The LED control unit 215 interfaces with the LED display screen to achieve large-screen display control of the LED display screen. Furthermore, the system control device 230 included in the seat management system 200 is added with LED display screen system configuration functionality, or both the system control device 230 and the seat device 240 included in the seat management system are added with LED display screen system configuration functionality, thereby improving the integration of the seat management system 200. With this design, users do not need to perform LED display screen system configuration operations on an LED control terminal independent of the seat management system 200, providing users with an efficient and convenient operating experience and improving the efficiency of system configuration of the large screen in the seat management system.

[0072] Improving the efficiency of system configuration for large screens in the seat management field can include at least improving the efficiency of debugging the display characteristics of the large screens and improving the efficiency of debugging the topological connection relationships of the large screens.

[0073] Optionally, such as Figure 4 As shown, the seat management host 210 also includes a video output unit 216. The video output unit 216 is connected to other displays besides the LED display, such as LCD and OLED displays. The video output card 216 is used to send video to other displays. Specifically, the seat device 240 receives a sixth control command input by the user; the sixth control command instructs the display of a second video on a display other than the LED display; in response to the sixth control command, the seat management host 210 acquires the second video and sends it to the video output unit 216; the video output unit 216 sends the second video to the display other than the LED display.

[0074] Optionally, such as Figure 4 As shown, at least one type of video source may include a local video source and a network video source; the video input unit 214 may include a local video input unit 217 and a network decoding unit 218. The local video input unit 217 is connected to the local video source via an audio / video transmission line, and the network decoding unit 218 is connected to the network video source via a communication line. In response to a first control command, the workstation management host 210 can acquire the first video from the remote device 250, the local video input unit 217, and the network decoding unit 218.

[0075] Optionally, the audio and video transmission lines may include: HDMI cables and display port (DP) cables.

[0076] This application embodiment can divide the various devices or units in the agent management system 200 (e.g., agent management host 210, fiber optic transmitting node 221, fiber optic receiving node 222, system control device 230, agent device 240, remote device 250, main control unit 211, fiber optic input unit 212, fiber optic output unit 213, video input unit 214, and LED control unit 215) into functional modules according to the above method example. For example, the various functions provided by each device or unit can be divided into various functional modules, or two or more functions provided by each device or unit can be integrated into one functional module. The above functional modules can be implemented in hardware or in software.

[0077] This embodiment also provides a computer-readable storage medium (including but not limited to disk storage, compact disc read-only memory (CD-ROM), optical storage, etc.) storing computer program code. When the computer program code is run on a computer, the computer executes the above-mentioned related method steps to implement a large-screen display method in a seat management scenario executed by the seat management system 200 in the above embodiment, or a large-screen display method in a seat management scenario executed by the seat management host 210.

[0078] This embodiment also provides a computer program product. When the computer program product is run on a computer, it causes the computer to perform the above-mentioned related steps to realize a large-screen display method in a seat management scenario executed by the seat management system 200 in the above embodiment, or a large-screen display method in a seat management scenario executed by the seat management host 210.
