Description

Technical Field

[0001] This invention relates to the field of multimedia information transmission technology, specifically to a method for implementing a large-scale information publishing system. Background Technology

[0002] Large-scale information dissemination systems are software and hardware platforms designed for enterprises with over 1000 employees and more than 100 information dissemination points. They are used to manage and disseminate organizational notices, announcements, or promotional information. Traditional information dissemination systems are primarily implemented in three ways:

[0003] The method based on HDMI / VGA distribution and extension involves the control computer transmitting information to a multimedia player via a network or USB interface and setting the playback mode. The player outputs HDMI or VGA signals, which are then split into multiple paths by a splitter, and finally transmitted to the front-end display screen by an extender or optical transceiver. This multiple distribution and extension expands the distribution range. However, HDMI signals are analog signals, and the signal weakens with each distribution, limiting the scale of the information distribution system. Furthermore, deploying optical transceivers is costly.

[0004] One approach involves equipping each display screen with a multimedia player. The control computer transmits information and playback instructions to each player via a network, and the players connect directly to the screens via HDMI or VGA cables to play programs. However, multimedia players are expensive, and their hard drive storage poses a security risk of internal information leakage if the devices are lost or stolen.

[0005] The method of using professional information display screens: Each professional information display screen comes with its own multimedia player. The control computer connects to each screen via a network and transmits information and playback modes. The screen plays programs according to the settings. However, professional information display screens are customized products, with a small market size, high price, and difficult repair after equipment failure.

[0006] Furthermore, traditional information publishing systems require the construction of independent information publishing networks and lack power control for the display screens. This necessitates 24-hour continuous operation of the screens, wasting electricity, accelerating equipment wear and tear, and affecting their lifespan. Simultaneously, there is a lack of monitoring of equipment operating status; equipment damage is typically only detected through inspections or user feedback, which is detrimental to system efficiency. To address the shortcomings of existing technologies, this invention provides a method for implementing a large-scale information publishing system to solve the aforementioned problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a method for implementing a large-scale information publishing system. Through innovative network architecture design, it effectively solves the problems of poor signal transmission quality and limited scale in traditional systems, improving system stability and scalability. In terms of equipment, it reduces procurement costs while enhancing information security. Regarding power management and equipment monitoring, it realizes intelligent power control and real-time status monitoring of the display screen, reducing power waste and equipment wear, improving system reliability and maintenance efficiency, and providing enterprises with an efficient, safe, and reliable large-scale information publishing solution.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for implementing a large-scale information publishing system, comprising the following steps:

[0009] Step S1: Divide the existing enterprise network into three independent Virtual Local Area Networks (VLANs): VLANa is used for transmitting control commands and publishing materials; VLANb is dedicated to the broadcast transmission of multimedia signals; and VLANc is dedicated to the transmission of power control signals.

[0010] Step S2: Interconnect network devices via TRUNK links to enable communication between the three VLANs across devices;

[0011] Step S3: Connect the control computer and at least one multimedia player to VLANa to establish a control channel;

[0012] Step S4: Connect the transmitter of the HDMI network extender to the multimedia player and the receiver to the display screen, and transmit the HDMI-converted network signal in broadcast mode within VLAN b.

[0013] Step S5: Connect the smart PDU and power controller to VLAN c, and control the power supply of the display screen through the PDU socket;

[0014] Step S6: Set a timed task through the power controller to realize automatic power on / off of the display screen and power status monitoring.

[0015] Preferably, in step S4, each multimedia player corresponds to an independent VLANb broadcast domain, and multiple players isolate broadcast streams through different VLANb to avoid signal conflicts.

[0016] Preferably, step S6 includes real-time monitoring of the current data of each socket of the smart PDU, and automatically triggering a device fault alarm based on abnormal power consumption.

[0017] Preferably, the equipment fault alarm determination is achieved through the following formula:

[0018] If the rated operating current of the display screen is set to I_rated and the real-time monitoring current is set to I_real-time, then the abnormality coefficient K is defined as: K = |I_real-time - I_rated| / I_rated;

[0019] When K>α and duration t>T, the device is identified as faulty and an alarm is triggered; where α is the current deviation threshold with a preset range of 0.3-0.5, and T is the duration threshold with a preset range of 10-30 minutes.

[0020] Preferably, VLANa, VLANb, and VLANc are isolated from other business networks of the enterprise through VLANs, and neither the HDMI network extender nor the network device has data storage function.

[0021] Preferably, multiple multimedia players are configured and multiple VLANb broadcast domains are divided. Each broadcast domain is associated with a set of display screens to form an independent information publishing area, supporting the playback of differentiated content.

[0022] Preferably, the multimedia player, HDMI network extender, and display screen support dynamic resolution adaptation, enabling configuration and upgrades to 720P, 1080P, or 4K resolutions through device selection.

[0023] Preferably, in step S4, the multimedia player supports access to a cable TV signal source and broadcasts live TV programs to the display screen via an HDMI network extender.

[0024] Preferably, the physical location of the control computer, multimedia player, power controller, and intelligent PDU is not restricted, and network connectivity is achieved only through the corresponding VLAN.

[0025] Preferably, at least two control computers are configured to access VLANa to enable parallel control of the multimedia player by multiple operating terminals.

[0026] This invention discloses a method for implementing a large-scale information publishing system, which has the following beneficial effects:

[0027] 1. The implementation method of this large-scale information publishing system avoids signal interference by dividing independent virtual local area networks (VLANs) to transmit control commands, multimedia signals and power control signals separately. Furthermore, by using the network to transmit multimedia signals, it solves the problem of signal weakening after multiple distributions of traditional HDMI signals, enabling large-scale information publishing and breaking through the scale limitations of traditional systems.

[0028] 2. The implementation method of this large-scale information publishing system avoids configuring a separate multimedia player for each display screen or using expensive professional information publishing displays, thus reducing equipment procurement costs. At the same time, through a reasonable network architecture and equipment management, the risk of information leakage due to equipment loss or theft is reduced, improving system security.

[0029] 3. The implementation method of this large-scale information publishing system connects the intelligent PDU and power controller to a dedicated VLAN for power control signal transmission. By setting timed tasks on the power controller, the display screens are automatically turned on and off, avoiding power waste and equipment wear caused by 24-hour uninterrupted operation. Simultaneously, the system monitors the current data of each socket on the intelligent PDU in real time, automatically triggering equipment fault alarms based on abnormal power consumption. This facilitates timely detection and handling of equipment faults, improving system reliability and maintenance efficiency. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] Figure 1 This is a topology diagram of the information publishing system of the present invention;

[0032] Figure 2 This is a flowchart of the overall system architecture of the present invention. Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This application provides a method for implementing a large-scale information publishing system, which solves the problem that traditional large-scale information publishing systems are unable to meet the actual needs of enterprises in terms of signal transmission, equipment cost, security, power control, and equipment status monitoring as enterprises continue to expand and information publishing demands increase.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] This invention discloses a method for implementing a large-scale information publishing system, according to the appendix. Figure 1-2 As shown, it includes the following steps:

[0037] Step S1: Divide the existing enterprise network into three independent Virtual Local Area Networks (VLANs): VLANa is used for transmitting control commands and publishing materials; VLANb is dedicated to the broadcast transmission of multimedia signals; and VLANc is dedicated to the transmission of power control signals.

[0038] Step S2: Interconnect network devices via TRUNK links to enable communication between the three VLANs across devices;

[0039] Step S3: Connect the control computer and at least one multimedia player to VLANa to establish a control channel;

[0040] Step S4: Connect the transmitter of the HDMI network extender to the multimedia player and the receiver to the display screen, and transmit the HDMI-converted network signal in broadcast mode within VLAN b.

[0041] Step S5: Connect the smart PDU and power controller to VLAN c, and control the power supply of the display screen through the PDU socket;

[0042] Step S6: Set a timed task through the power controller to realize automatic power on / off of the display screen and power status monitoring.

[0043] This method divides the enterprise network into three independent VLANs, each undertaking different functions. Cross-device communication is achieved using trunk links, connecting various devices to their corresponding VLANs to enable independent transmission and management of control commands, multimedia signals, and power control signals. This allows for the construction of a large-scale information publishing system, enabling effective information dissemination, multimedia content display, and intelligent power control of the display screens. VLAN segmentation enhances network security and management flexibility; different types of data are transmitted in different VLANs, avoiding mutual interference, and facilitating independent management and maintenance of different functional modules.

[0044] In step S4, each multimedia player corresponds to an independent VLANb broadcast domain, and multiple players isolate broadcast streams through different VLANb to avoid signal conflicts.

[0045] Each multimedia player is assigned an independent VLANb broadcast domain. Utilizing the isolation features of VLANs, the broadcast streams of different players are isolated from each other. This avoids conflicts between the broadcast signals of multiple multimedia players, ensuring that each player can transmit multimedia signals to the display screen normally and stably. This improves system stability and reliability, reduces problems such as screen stuttering and flickering caused by signal conflicts, and guarantees the quality of information delivery.

[0046] Step S6 includes real-time monitoring of the current data of each socket in the smart PDU and automatically triggering equipment fault alarms based on abnormal power consumption. The power controller monitors the current data of each socket in the smart PDU in real time, and automatically triggers equipment fault alarms when an abnormal current is detected. This method can promptly detect abnormal power consumption in devices such as displays, avoiding equipment damage or safety accidents caused by power problems. It achieves real-time monitoring of the power status of equipment, improves system safety and maintainability, and reduces the workload of manual inspections.

[0047] Equipment fault alarm judgment is achieved through the following formula:

[0048] If the rated operating current of the display screen is set to I_rated and the real-time monitoring current is set to I_real-time, then the abnormality coefficient K is defined as: K = |I_real-time - I_rated| / I_rated;

[0049] When K>α and duration t>T, the device is identified as faulty and an alarm is triggered; where α is the current deviation threshold with a preset range of 0.3-0.5, and T is the duration threshold with a preset range of 10-30 minutes.

[0050] The above-described equipment fault alarm judgment formula facilitates accurate determination of whether equipment has malfunctioned and promptly triggers alarms when conditions are met, allowing staff to handle the situation in a timely manner. This formula provides a scientific and accurate fault diagnosis method, avoiding misjudgments and omissions, and improving the timeliness and accuracy of fault handling.

[0051] VLANs a, b, and c are isolated from other business networks within the enterprise via VLANs, and neither the HDMI network extender nor other network devices have data storage capabilities. VLAN isolation separates the information publishing system's network from other business networks while restricting the data storage capabilities of the HDMI network extender and network devices. This ensures the network security of the information publishing system, prevents other business networks from being affected by the information publishing system, and avoids the risk of data leakage. It improves system security and confidentiality, meets the enterprise's network security requirements, and protects the enterprise's core data and business security.

[0052] Multiple multimedia players are configured and multiple VLANb broadcast domains are defined. Each broadcast domain is associated with a group of displays to form an independent information publishing area, supporting differentiated content playback. This method enables multi-regional, differentiated information publishing in large-scale information publishing systems, meeting the personalized needs of different regions or scenarios. It improves the flexibility and targeting of information publishing, better adapts to the needs of different user groups, and enhances the effectiveness of information publishing.

[0053] Multimedia players, HDMI network extenders, and displays support dynamic resolution adaptation, enabling configuration and upgrades to 720P, 1080P, or 4K resolutions through device selection. This method allows the system to adapt to different resolution display requirements, allowing users to choose the appropriate resolution based on their needs, while also facilitating system upgrades and expansions. It improves system compatibility and scalability, reduces the cost and difficulty of system upgrades, and extends the system's lifespan.

[0054] In step S4, the multimedia player supports access to a cable TV signal source and broadcasts live TV programs to the display screen via an HDMI network extender. This method enriches the content sources of the information publishing system, allowing it to play live TV programs in addition to publishing materials, thus meeting users' diverse information needs. It increases the system's functionality and application scenarios, enhances its practicality and attractiveness, and better satisfies users' entertainment and information acquisition needs.

[0055] The physical location of the control computer, multimedia player, power controller, and smart PDU is unrestricted; network connectivity is achieved solely through their corresponding VLANs. This method improves system deployment flexibility, allowing users to freely arrange device locations based on actual site conditions and needs, reducing deployment difficulty and costs. It also facilitates system installation and maintenance, minimizes inconvenience caused by device location limitations, and enhances system scalability and adaptability.

[0056] Configure at least two control computers to access VLANa, enabling multiple operating terminals to control the multimedia player in parallel. This method improves the system's operational convenience and reliability, allowing multiple operating terminals to control the multimedia player simultaneously, avoiding system inoperability issues caused by single points of failure. It facilitates system management and operation by different personnel, improves work efficiency, and enhances system stability and reliability.

[0057] Example 1: Enterprise Office Area Information Publishing System

[0058] Implementation method:

[0059] In the enterprise network within the office area, three independent virtual local area networks (VLANs) are created: VLANa, VLANb, and VLANc.

[0064] By setting timed tasks through the power controller, the display screen can be automatically turned on and off on weekdays, and the power consumption status can be monitored in real time.

[0065] Advantages: It enables unified release and management of information in the enterprise office area, improves the efficiency and accuracy of information transmission, and reduces energy consumption and equipment maintenance costs through timed power on / off and power consumption monitoring functions.

[0066] Example 2: Multi-area advertising playback system in shopping malls

[0067] Implementation method:

[0068] The mall's network is divided into three independent virtual local area networks: VLANa, VLANb, and VLANc.

[0069] By connecting network devices within the shopping mall via TRUNK links, it is ensured that the three VLANs can communicate across devices.

[0070] Set up a control computer in the mall's management office, install multimedia players on each floor and in each area of ​​the mall, connect them to VLANa, and establish a control channel.

[0071] Display screens are installed in the advertising spaces on each floor. The transmitter of the HDMI network extender is connected to the multimedia player, and the receiver is connected to the display screen. An independent VLANb broadcast domain is assigned to the multimedia player on each floor, and the HDMI-converted network signal is transmitted in broadcast mode within VLANb.

[0072] The smart PDU and power controller are installed in the mall's power distribution room, connected to VLAN c, and the power supply of the display screen is controlled through the PDU socket.

[0073] By setting timed tasks through the power controller, the display screen can be automatically turned on and off during different business hours, and the power consumption status can be monitored in real time.

[0074] By configuring multiple control computers to access VLANa, mall managers and advertisers can control the multimedia player in parallel through different control computers to achieve the playback of differentiated content.

[0075] Advantages: It meets the needs of multi-area advertising in shopping malls, realizes precise delivery and differentiated display of advertising content, improves advertising effectiveness and the commercial value of shopping malls, and improves system management efficiency and security through multi-operation terminal parallel control and power consumption monitoring functions.

[0076] The implementation method of this large-scale information publishing system effectively solves the problems of poor signal transmission quality and limited scale of traditional systems through innovative network architecture design, thereby improving the stability and scalability of the system. In terms of equipment, it reduces procurement costs while enhancing information security. In terms of power management and equipment monitoring, it realizes intelligent power control and real-time status monitoring of the display screen, reducing power waste and equipment wear and tear, improving system reliability and maintenance efficiency, and providing enterprises with an efficient, safe and reliable large-scale information publishing solution.
