Description

Technical Field

[0001] The present invention relates to the field of education and learning technology, and in particular to a distributed central control network architecture and application system for multimedia classrooms. Background Art

[0002] With the rapid development of information technology, distributed interactive learning systems have gradually become a research hotspot in the field of education. This system integrates teaching equipment, teaching resources and teaching activities through network technology, realizing intelligent control of the teaching environment, sharing of teaching resources and diversification of teaching interactions. In traditional classroom control systems, the signals of all devices are usually centrally managed by a central controller. Although this architecture is simple, it has some shortcomings as the number of multimedia devices in the classroom continues to increase and the requirements for system flexibility and scalability are increasing;

[0003] Traditional classroom central control systems usually adopt a centralized architecture, with a central controller managing all device signals. With the increasing number of multimedia devices in the classroom and the increasing requirements for flexibility and scalability, the risk of single point failure is high: failure of the central controller causes the entire system to crash; information transmission efficiency is low: signals need to be forwarded through the central controller, causing transmission delays and congestion; scalability is poor: adding devices requires reconfiguring the central controller, and the maintenance cost is high. Therefore, a distributed central control network architecture and application system for multimedia classrooms is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the above-mentioned background technology, to provide a distributed central control network architecture for multimedia classrooms, to overcome the problems existing in traditional centralized central control systems, to build a flexible, efficient and reliable classroom central control system, and to propose a distributed central control network architecture and application system for multimedia classrooms.

The central control node is used to control devices in a specific area or function and process signals. The signal acquisition device is used to collect signal information of each device. The network device is used to connect each node to achieve data transmission and communication. The user terminal is used for user interaction with the central control network. The central control nodes select the optimal routing path through an intelligent routing algorithm to ensure the reliability and efficiency of signal transmission, and use the IP protocol for data interaction to achieve information sharing and control coordination.

[0007] Preferably, the central control node adopts a hierarchical network control structure, and the central control node includes a processor, a memory and a communication module, the processor is used to execute control instructions and process signals, the memory is used to store control programs and device information, and the communication module is used to communicate with other nodes and devices.

[0011] Intelligent routing algorithms can perceive changes in the network environment in real time, including link status, traffic distribution, device performance, etc. By collecting and analyzing this information, the algorithm can understand the overall picture of the network.

[0012] Path selection:

[0013] The intelligent routing algorithm selects the optimal routing path based on the collected network status information. The basis for path selection may include but is not limited to link cost, delay, bandwidth utilization, device load, etc.

[0014] Dynamic Adjustment:

[0015] Intelligent routing algorithms can dynamically adjust routing paths based on real-time changes in the network. For example, when a link is congested or fails, the algorithm will automatically recalculate and select a new optimal path to ensure the reliability and efficiency of data transmission.

[0016] Learning and Optimization:

[0017] Intelligent routing algorithms (such as those based on machine learning) can continuously learn and optimize path selection strategies through historical data and real-time feedback.

[0026] The S4 node performs corresponding control operations according to the instructions and feeds back the results to the terminal device.

[0027] Preferably, the intelligent routing algorithm selects the optimal routing path based on factors such as network topology, node load and signal priority.

[0028] Compared with the prior art, the present invention provides a distributed central control network architecture for multimedia classrooms, which has the following beneficial effects:

[0029] 1.

[0030] 2. The distributed central control network architecture of the present invention divides the central control system into multiple functional nodes, each of which is responsible for the control and signal processing of a specific area or function. Even if a node fails, other nodes can still work normally, thus greatly improving the reliability of the system;

[0031] 3. In the distributed central control network architecture of the present invention, each node is responsible for the control of a specific area or function, and the signal transmission distance is greatly reduced.

The intelligent routing algorithm can dynamically select the optimal routing path according to the changes in the network environment. The basis for path selection includes link cost, delay, bandwidth utilization, equipment load, etc., to ensure the efficiency and reliability of signal transmission.

[0033] Figure 2 The present invention is a schematic diagram of an application system of a distributed central control network architecture for a multimedia classroom. DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-2 ,A distributed central control network architecture for a multimedia classroom,Implementation 1: Construction and equipment configuration of a multimedia classroom,In a newly built multimedia classroom, a distributed central control network architecture is deployed in the following manner:

[0036] Central control node: Central control nodes are set up in different areas of the classroom. For example, a main central control node is set up in the podium area to control multimedia teaching equipment (such as projectors and computers); an auxiliary central control node is set up at the back of the classroom to control lighting equipment and air-conditioning equipment. Each central control node uses a high-performance processor, large-capacity memory and high-speed communication module.

[0037] Signal acquisition equipment: Install sensors on multimedia equipment, lighting equipment, air conditioning equipment, etc. For example, install temperature sensors and working status sensors on projectors, install light intensity sensors on lighting equipment, and install temperature and wind speed sensors on air conditioning equipment. Data converters convert the analog signals collected by these sensors into digital signals.

[0038] Network equipment: Enterprise-level switches and routers are used to ensure efficient and stable data exchange and forwarding. The network interface uses a Gigabit Ethernet interface to ensure high-speed connection.

[0039] User terminal: Teachers are equipped with laptops and mobile phones as user terminals, both of which are installed with special control software and connected to the central control network via a wireless network.

[0040] Example 2: Application of intelligent routing algorithm

[0041] During a classroom teaching, the teacher sent instructions to turn on the projector and adjust the brightness of the classroom lights through the mobile terminal:

[0042] State perception: The intelligent routing algorithm perceives the state of each link in the current network in real time, including whether it is congested, delay, etc., and understands the load status of each central control node.

[0043] Path selection: Based on the collected information, the algorithm selects a path with light load and low latency to transmit the instructions from the teacher's mobile terminal to the main central control node in the podium area.

[0044] Dynamic adjustment: During the instruction transmission process, if there is a sudden change in traffic in the network, causing congestion in the originally selected path, the algorithm dynamically adjusts the routing path to ensure that the instructions can be transmitted quickly and accurately.

[0045] Learning and optimization: After many similar operations, the algorithm continuously optimizes the path selection strategy by analyzing historical data and real-time feedback, making subsequent instruction transmission more efficient.

[0046] Example 3: Comprehensive control of classroom environment:

[0047] The teacher sent instructions through the computer terminal to lower the air conditioning temperature and turn off some lighting equipment.

[0048] After the command is transmitted to the central control network through the network, the intelligent routing algorithm quickly forwards the command to the central control node responsible for the air-conditioning equipment and lighting equipment.

[0049] The processor of the central control node executes control instructions, controls the air conditioner to lower the temperature, and turns off some lighting equipment.

[0050] After the node executes the operation, the execution result will be fed back to the teacher's computer terminal, and the teacher can know in real time whether the control is successful.

[0051] Example 4: Fault detection and alarm

[0052] During normal teaching, the central control node responsible for the projector fails:

[0053] The fault detection and alarm module monitors the abnormal status of the central control node in real time.

[0054] Immediately send out an alarm signal and notify the administrator via SMS or pop-up window of control software.

[0055] At the same time, other central control nodes automatically take over the control functions of some projectors to ensure that teaching is not greatly affected.

[0056] Example 5: System expansion and upgrade

[0057] As school teaching needs increase, smart curtain devices need to be added to classrooms:

[0058] The newly installed smart curtain equipment is equipped with corresponding signal acquisition equipment and control modules.

[0059] Add a new central control node in the classroom to be responsible for the control of curtain equipment.

[0060] The new central control node is connected to the original distributed central control network through network equipment, without the need for large-scale transformation and reconfiguration of the original system.

[0061] The distributed central control network architecture and application system significantly improves the system reliability, control efficiency and scalability, and enhances the user experience and system performance through distributed architecture, intelligent routing algorithms, IP protocol adaptation and other technologies. Specifically, the distributed architecture avoids single point failures, and the mutual backup between nodes ensures the stable operation of the system; the intelligent routing algorithm optimizes the path selection and reduces the delay and congestion of signal transmission; the hierarchical network control structure and flexible scalability make the system more modular, easy to expand and maintain; the diversity of user terminals and the real-time feedback mechanism improve the convenience of operation and the stability of the system. The distributed central control network architecture divides the central control system into multiple functional nodes, each of which is responsible for the control and signal processing of a specific area or function. Even if a node fails, other nodes can still work normally, which greatly improves the reliability of the system.
