Description

Technical Field

[0001] The present invention belongs to the field of smart classrooms, and in particular relates to a multifunctional central control system. Background Art

[0002] With the continuous development of society, the importance of information exchange and communication has been increasing day by day. Various audio-visual equipment, projection equipment, teaching equipment and conference systems are widely used in all walks of life. Modern conference rooms and audio-visual teaching rooms are no longer the simple configuration of a podium, a chair and a microphone, but have been replaced by various advanced multimedia equipment. These devices include smart large screens, smart cameras, sound amplification equipment, multimedia computers, electric screens, etc. Some large conference rooms are also equipped with simultaneous interpretation systems, electronic voting systems, large-screen projection and multi-screen switching systems.

[0003] However, the simultaneous use of multiple devices also brings about complex device operation issues. Users not only need to turn on the power of each device one by one, but also need to control the lights, adjust the temperature, manage the curtains, switch the main display screen, and monitor the teaching or meeting content in real time. In this context, the "central control system" that can centrally manage and control various resources in the smart classroom came into being.

[0004] However, although the existing central control system solutions can achieve equipment control to a certain extent, they still have many limitations, such as:

[0005] Single function, difficult to coordinate operation: Most existing systems are single-point control, unable to build a complete control system, and difficult to take into account multiple needs such as remote device control, local device control, and teaching content monitoring.

[0006] Lack of data processing capabilities: Existing solutions are unable to perform corresponding automated processing based on classroom data collected by equipment. For example, they are unable to automatically adjust temperature and humidity, broadcast reminders, force screen dominance, or take over classrooms based on environmental data.

[0007] Poor compatibility: The operation of the central control panel system usually depends on a specific operating system or software. There are technical barriers between different manufacturers, and their respective control systems are often incompatible with other manufacturers' equipment, limiting the scalability and flexibility of the system.

[0008] Network dependence and security risks: Existing solutions generally rely on external network connections to achieve intelligent functions, but this approach increases the risk of data leakage and privacy leakage. Criminals may exploit loopholes in the intelligence of devices to conduct illegal intrusion or control, further amplifying security issues.

[0009] To sum up, the current central control system is difficult to meet the comprehensive needs of smart classrooms and multimedia conference rooms in terms of intelligence, compatibility, security and convenience. Therefore, a new smart central control system is urgently needed. Summary of the invention

[0010] The present invention discloses a multifunctional central control system to solve the problem that the prior art is difficult to meet the comprehensive requirements of smart classrooms in terms of intelligence, compatibility, safety and convenience.

[0011] In order to solve the above technical problems, the embodiments of the present invention disclose the following technical solutions:

[0024] Also, at a second set time after the course ends in the timetable data, a remote control command is sent to the central control host of the corresponding target classroom, so that the IoT devices and environmental sensors connected to the central control host stop running or run according to a preset end-of-get out of class mode.

[0025] Optionally, when the central control host receives a class control instruction sent by the central control panel during a non-class period in the class schedule data, it sends a control signal to the connected IoT devices and environmental sensors to make the IoT devices and environmental sensors operate in class mode.

[0026] Optionally, when the central control host receives the get out of class end control command sent by the central control panel, it sends a control signal to the connected IoT device and environmental sensor, so that the IoT device and environmental sensor stop running or run in standby mode after a second set time.

[0027] Optionally, the remote centralized control platform includes an AI large model analysis module, which is configured to obtain and analyze classroom videos captured by cameras.

[0037] Figure 1 A schematic diagram of the structure of a multifunctional central control system provided by an embodiment of the present invention is applied to uniformly manage and monitor devices in multiple smart classrooms, such as Figure 1 As shown, a set of central control host 1 and central control panel 2 are set up in each target classroom. The central control host 1 and the central control panel 2 are connected through a serial port (such as TypeC to RJ45 wiring harness) or Bluetooth, and the RS232 protocol is used to transmit data. At the same time, a symmetric encryption algorithm is used to ensure communication security.

[0038] In addition, the system also includes a remote centralized control platform 3 connected to each central control host 1 via a cloud server, wherein:

[0039] The cloud server is the central node of the system. It can communicate with the central control host 1 in the target classroom and is responsible for receiving and storing the IoT device operation data, classroom environment indicators and local control instructions from all target classrooms. The cloud server synchronizes this data to the remote centralized control platform 3 to provide support for global monitoring and centralized management. At the same time, the cloud server also distributes remote control instructions to the corresponding central control host 1 to ensure the real-time and efficient remote management.

[0040] The remote control platform 3 is the central management unit of the system, which is used for global intelligent control and unified management. It can receive the IoT device operation data and classroom environment monitoring data transmitted by the cloud server, and use the built-in AI large model analysis module to perform intelligent analysis of the classroom environment, equipment operation status and teaching behavior.

[0041] (I) Central control host

[0042] The central control host 1 is configured to receive local control instructions from the central control panel 2 of the same group and remote control instructions from the remote centralized control platform 3.

[0043] The central control panel 2 provides a user interaction interface, through which the user inputs local control commands, such as adjusting the light brightness, controlling the air conditioning temperature, switching the screen display content, starting and ending classes, etc. The local control commands are transmitted to the central control host 1 via the serial port or Bluetooth communication method. The central control host 1 parses the commands and generates corresponding control signals to control the relevant IoT devices to complete the tasks.

[0044] At the same time, the central control host 1 can also receive remote control instructions issued by the remote centralized control platform 3. The remote centralized control platform 3 generates remote control instructions based on the teaching schedule, classroom environment indicators or other intelligent analysis results, such as starting the air conditioner and lights in advance, turning off unused equipment, or adjusting the working mode of the monitoring equipment. The remote control instructions are transmitted to the central control host 1 through the intranet, and the central control host 1 will also control the IoT devices and / or link sensors in the classroom according to the content of the instructions.

[0045] The central control host 1 is also communicatively connected with a variety of IoT devices installed in the target classroom, and is configured to generate control signals according to the received control instructions and send them to the corresponding IoT devices, as well as collect the operating data of the connected IoT devices and send them to the central control panel 2 and the remote control platform 3 of this group.

[0046] The central control host 1 establishes communication connections with the lighting modules, curtains, electric air conditioners, large screens, cameras, sound receiving and amplifying devices and other IoT devices in the classroom. When receiving local control instructions from the central control panel 2 or remote control instructions from the remote centralized control platform 3, it generates corresponding control signals according to the specific content of the control instructions. For example, when the instruction requires closing the curtains or adjusting the air conditioner temperature, the central control host 1 will transmit the control signal to the corresponding device to execute the control instruction.

[0047] The central control host 1 is not only responsible for sending control signals, but also has data collection functions. It can monitor and collect the operating data of the connected IoT devices in real time, such as the current status of the device (such as whether the light is on, the screen display content), operating parameters (such as air conditioning temperature, camera angle) and the usage time of the device. The operating data will then be sent to the central control panel 2 of the group for users to view and manage in real time, and will also be synchronized to the remote centralized control platform 3.

[0048] The central control host 1 is also connected to communicate with various environmental sensors installed in the target classroom, and is configured to collect monitoring data of the connected environmental sensors as classroom environment indicators, and send them to the central control panel 2 and the remote centralized control platform 3 of this group.

[0049] The central control host 1 is connected to the temperature and humidity sensors, CO2 concentration sensors, CO concentration sensors, air quality sensors and infrared sensors in the classroom, and can monitor key parameters in the classroom environment in real time, such as air temperature, humidity, quality, carbon dioxide concentration, carbon monoxide concentration and information on personnel activities in the classroom.

[0050] The central control host 1 processes the data collected by the environmental sensors and integrates the data into classroom environmental indicators. For example, the comprehensive temperature and humidity data can reflect the comfort level of the classroom, and the carbon dioxide concentration can be used as a basis for evaluating air quality. The central control host 1 sends the environmental indicators to the central control panel 2 of the group in real time, so that users in the classroom can intuitively understand the current environmental conditions and make corresponding adjustments, such as turning on the ventilation system or adjusting the air conditioning mode.

[0051] The central control host 1 synchronously transmits the classroom environment indicators to the remote centralized control platform 3 for global monitoring and analysis. The classroom environment indicators can be used to optimize the classroom environment control strategy, such as automatically controlling the operation of ventilation and air-conditioning equipment, or early warning of possible environmental abnormalities, thereby improving the comfort and safety of the teaching environment.

[0052] (II) Central control panel

[0053] The central control panel 2 is configured to display the operating data of the IoT devices and classroom environment indicators to the user, and generate local control instructions based on the information input by the user.

[0054] The operating data includes the current status of the equipment in the classroom, such as whether the lights are on, the degree of opening and closing of the curtains, the temperature setting of the air conditioner, the content playback status of the large screen, etc. The classroom environment indicators are collected by the connected environmental sensors, covering information such as temperature and humidity, air quality (such as CO2 concentration) and activity detection. The above information can be presented in a graphical interface, allowing users to intuitively understand the operating status and environmental conditions of the equipment in the classroom.

[0055] The central control panel 2 supports users to manage devices and environments through touch screen, buttons or other input methods. When users input commands such as adjusting light brightness, closing curtains or setting air conditioning temperature, the central control panel 2 will generate corresponding local control commands based on these inputs. After the commands are processed, they are transmitted to the central control host 1 through the serial port or Bluetooth to further control the IoT devices to perform operations.

[0056] In addition, the Central Control Panel 2 improves the user's control efficiency over classroom equipment and environment through a friendly user interface design and a quick response mechanism. It supports multiple operating systems (such as Hongmeng OS), ensuring compatibility and flexibility, and is suitable for different teaching scenario requirements.

[0057] (III) Remote Control Platform

[0058] The remote centralized control platform 3 is configured to monitor the operation data of all IoT devices and classroom environment indicators sent by the central control host 1, and generate remote control instructions to send to the corresponding central control host 1 when the operation data or classroom environment indicators are abnormal.

[0059] The remote centralized control platform 3 can receive the IoT device operation data and classroom environment indicators uploaded by the central control host 1 distributed in each classroom in real time, and dynamically monitor and analyze the received data. When it is found that the device operation data or environmental indicators are abnormal, such as the device operation status is inconsistent with expectations, and the classroom environmental parameters exceed the set safety range or comfort range, the remote centralized control platform 3 will respond immediately, generate corresponding remote control instructions and send them to the corresponding central control host 1, and the central control host 1 will perform the corresponding adjustment operations. For example, if the CO2 concentration in a classroom is detected to be too high, the remote centralized control platform 3 can send a remote control instruction to the central control host 1 to turn on the ventilation system or adjust the air conditioning settings.

[0060] The remote centralized control platform 3 is configured to generate remote control instructions according to the control signal input by the user, and send the instructions to the corresponding central control host 1 to achieve centralized remote control of the Internet of Things devices and environmental sensors in the classroom.

[0061] When the user inputs a control signal through the interactive interface of the remote centralized control platform 3, the remote centralized control platform 3 will parse the input command, clarify the target classroom, equipment type and operation requirements, and then generate standardized remote control commands and transmit them to the central control host 1 in the designated classroom. After receiving the command, the central control host 1 will parse its content and send a specific control signal to the connected IoT device or environmental sensor, so that the device performs the corresponding operation according to the command. For example, if the user inputs a control signal for publishing an announcement, the remote centralized control platform 3 will play the set announcement content on the teaching screens of all classrooms according to the signal.

[0062] In the embodiments disclosed in the present invention, IoT devices include but are not limited to curtains, lighting modules, air conditioners, gateways, teaching screens, cameras, sound receiving and amplifying equipment, HDMI video matrix (input and output of HDMI signals), IoT serial port control, smart door locks and other equipment required in the classroom.

[0063] In the embodiments disclosed in the present invention, environmental sensors include but are not limited to temperature and humidity sensors, CO2 concentration sensors, CO concentration sensors, infrared sensors, air quality sensors, light sensors, smoke sensors, noise sensors and other sensors for monitoring the environment in the classroom.

[0064] In one embodiment disclosed in the present invention, the remote centralized control platform 3 pre-sets the timetable data of each target classroom, and sends a remote control instruction to the central control host 1 of the corresponding classroom at the first set time before the start of the course in the timetable data, so that the central control host 1 controls the connected IoT devices and environmental sensors to operate in accordance with the preset class mode. Also, at the second set time after the end of the course in the timetable data, a remote control instruction is sent to the central control host 1 of the corresponding target classroom, so that the IoT devices and environmental sensors connected to the central control host 1 stop operating or operate in accordance with the preset end-of-get out of class mode.

[0065] The remote centralized control platform 3 pre-sets the timetable data of each target classroom, including the start and end time of each class, the usage of the classroom, and related setting requirements. The timetable data is usually entered in advance based on the semester arrangement and is associated with the classroom environment requirements, the usage of teaching equipment, etc.

[0066] The environment (including temperature, humidity, lighting, air quality, etc.) and equipment (such as air conditioning, lighting, curtains, sound, etc.) of each classroom will set the teaching mode according to teaching needs. For example:

[0067] According to the season and class schedule, the air conditioner is adjusted to a suitable temperature before class; the opening and closing of curtains or the brightness of lights are automatically controlled to ensure that there is enough light in the classroom; the air conditioner or air purifier is turned on in advance to ensure that the air quality meets the appropriate standards, especially in the control of CO2 concentration and air pollutants such as PM2.5; in some special courses or activities, the sound system is adjusted to ensure clear sound effects; smoke sensors, access control systems, etc. are set in combination with class schedule data to ensure safety checks before class.

[0068] Before the start of each class, the remote centralized control platform 3 automatically identifies the class time of each classroom according to the preset class schedule data, and sends a remote control instruction to the corresponding classroom central control host 1 at a specified time before the class.

[0069] After receiving the remote control command, the central control host 1 in each classroom will adjust the connected IoT devices and environmental sensors according to the command. The remote centralized control platform 3 will control all devices and sensors to automatically perform self-checks to ensure that all IoT devices are working properly and environmental sensors are accurate. If a device or sensor fails, the remote centralized control platform 3 can receive an alarm message and take timely measures.

[0070] The remote control platform 3 can not only ensure the comfort of the classroom environment, but also realize energy management and safety management. For example, air conditioning, lighting and other equipment are only enabled when needed to avoid wasting energy and ensure the efficiency and performance of equipment operation. When abnormal conditions are detected (such as excessively high CO2 concentration, poor air quality, equipment failure, etc.), the remote control platform 3 will automatically alarm and activate the corresponding safety mechanism to ensure the safety of students and teachers.

[0071] After the course ends and the second set time is reached, the central control host 1 of the classroom stops controlling the connected IoT devices and environmental sensors through remote control instructions to ensure that all unnecessary devices can be automatically turned off when no one is in the classroom, so as to save energy, improve efficiency and ensure the long-term stable operation of the equipment. For example,

[0072] Turn off the air conditioner and heater. After the course is over, temperature control equipment such as air conditioners and heaters no longer need to maintain the current temperature. The relevant equipment can be turned off through the central control host 1.

[0073] Turn off the lighting equipment. If the classroom lighting system does not have intelligent sensing (such as light or human body sensing control), you can control the lights in the classroom to turn off to avoid unnecessary energy waste.

[0074] Close the curtains and control them to return to the default closed state to prevent direct sunlight from shining into the classroom and affecting the life of the equipment or the indoor temperature.

[0075] Turn off the air purification system. If the air quality meets the standard or the classroom is empty, turn off the air purifier or ventilation system to save energy.

[0076] In addition, the classroom's environmental sensors (such as temperature and humidity sensors, CO2 concentration sensors, PM2.5 sensors, etc.) will stop working or enter standby mode after the course ends:

[0077] In the process of sending control instructions, the remote control platform 3 can also monitor equipment and detect faults. If a device fails when executing a shutdown command (such as the air conditioner cannot be turned off, the lights do not go out, etc.), the remote control platform will issue an alarm to ensure that the classroom environment will not cause waste or affect safety due to equipment failure.

[0078] In one embodiment disclosed in the present invention, when the central control host 1 receives a class control instruction sent by the central control panel 2 during a non-class period in the class schedule data, it sends a control signal to the connected IoT devices and environmental sensors, so that the IoT devices and environmental sensors operate according to a preset class mode.

[0079] Non-class time usually refers to the idle time in the classroom in the class schedule, that is, the time when no teaching activities are carried out, including before class, after class, and during breaks. The IoT devices and environmental sensors in the classroom need to be adjusted according to needs to ensure a suitable environment during class or save energy.

[0080] When the central control host 1 receives the class control instruction sent by the central control panel 2 during the non-class period in the class schedule data, it will start the IoT devices that need to be run in the classroom (such as air conditioning, lights, curtains, audio, etc.) according to the preset class mode, and activate the classroom's environmental sensors (such as temperature and humidity sensors, CO2 concentration sensors, PM2.5 sensors, etc.) to start monitoring the environment.

[0081] If the device fails to respond to commands normally (such as the air conditioner cannot be started, the sensor fails, etc.), the central control host 1 will promptly feedback the fault information to the management personnel to ensure that the problem can be quickly handled. At the same time, the sensor data (such as temperature and humidity, CO2 concentration, etc.) will be fed back to the centralized control platform, and the management personnel can view the real-time environmental data at any time to ensure that the classroom status meets the preset requirements.

[0082] In one embodiment disclosed in the present invention, when the central control host 1 receives the get out of class ending control instruction sent by the central control panel 2, it sends a control signal to the connected Internet of Things devices and environmental sensors, so that the Internet of Things devices and environmental sensors stop running or run in standby mode after a second preset time.

[0083] When the second preset time has passed after the central control host 1 receives the end-of-get out of class control command sent by the user through the central control panel 2, a control signal is sent to the connected IoT devices and environmental sensors. IoT devices such as air conditioners or heating equipment, classroom lights, curtain systems, audio equipment, and large screens will automatically shut down or enter standby mode; environmental sensors in the classroom stop real-time monitoring and enter standby or shutdown mode.

[0084] In one embodiment disclosed in the present invention, the Internet of Things device includes at least a camera; the remote centralized control platform 3 includes an AI large model analysis module, which is configured to obtain and analyze the classroom video captured by the camera, and when the deviation between the teaching content in the classroom video and the preset teaching content exceeds a threshold, or when preset sensitive information appears in the teaching content, a reminder message is generated and sent to the corresponding central control panel 2.

[0085] The camera collects real-time video in the classroom, recording the teacher's explanations and classroom activities, ensuring that visual information of the entire teaching process can be obtained. The camera can be set to cover the entire classroom or a specific area to ensure comprehensive capture of teaching content.

[0086] The camera is not only used to record teaching videos, but also can transmit video streams to the remote centralized control platform 3 in real time, providing raw data for the AI ​​large model analysis module.

[0087] The AI ​​large model analysis module uses powerful computing power to conduct in-depth analysis of teaching videos. It mainly includes the following functions:

[0088] First, the AI ​​big model will perform voice recognition, image analysis and semantic understanding on the content in the classroom video, extract the teaching content in the video and compare it with the preset teaching content. For example, you can set the expected course outline or knowledge points, and the AI ​​analysis module will identify the content explained by the teacher and judge the deviation from the preset content.

[0089] Secondly, if the deviation of the teaching content from the preset teaching content exceeds the set threshold, the AI ​​model will mark the video and generate a reminder message. These deviations can include missing, inaccurate or part of the content that exceeds the teaching objectives, thus helping to ensure the quality and consistency of teaching.

[0090] At the same time, the AI ​​model can also identify whether the classroom video involves sensitive information, such as politically sensitive information, moral or legal issues, etc. If the preset sensitive information is detected, the system will immediately trigger the alarm mechanism and generate relevant reminder information.

[0091] Once the AI ​​large model analysis module detects the above abnormal situation, it will immediately generate a reminder message and send it to the corresponding central control panel 2. The central control panel 2 can view the alarm and reminder information in real time through the interface to decide whether further intervention measures are needed, such as adjusting the teaching content, communicating with teachers or taking other actions.

[0092] The AI ​​big model analysis module can also identify the behaviors of teachers and students in classroom videos. For example, the teacher's teaching posture, explanation frequency, blackboard writing movements, etc., as well as the students' concentration, number of hand raising, interactive participation, etc. can all be analyzed and quantified into data, and further processed to generate a classroom quality report.

[0093] In one embodiment disclosed in the present invention, the remote centralized control platform 3 is configured to perform unified management of IoT devices in multiple target classrooms, as well as real-time inspection and fault recovery operations.

[0094] The remote centralized control platform 3 can be used to configure and initialize the equipment in each classroom, set the working mode and control method of the equipment, etc. For example, the air conditioner in the classroom can be set to start before class, and the light can be automatically adjusted during class. When multiple classrooms need to be managed at the same time, the remote centralized control platform 3 can coordinate the operation of equipment between different classrooms. For example, adjust the air conditioning temperature of the entire floor, centrally manage the lights and sound systems of all classrooms, etc.; view the operating status of all equipment in each classroom in real time to ensure that the equipment is operating normally and discover potential problems in time.

[0095] The remote centralized control platform 3 is equipped with a real-time inspection function to continuously monitor the health status of each classroom device, so as to promptly detect device failures and anomalies, and avoid the device being in a faulty state for a long time, thereby affecting teaching activities.

[0096] Through the feedback interface with the IoT device, the platform can check the operating status of the device in real time. For example, it can monitor the temperature setting of the air conditioner, the opening and closing status of the curtains, the shooting status of the camera, etc. If the device fails (such as failing to start, stopping working, etc.), the remote centralized control platform 3 will generate an alarm message.

[0097] In addition, the remote control platform 3 will regularly collect and analyze the operating data of the equipment. If a device has performance degradation or abnormal fluctuations (such as excessive fluctuations in air-conditioning temperature, unstable operation of the air purifier, etc.), the remote control platform 3 will automatically detect and respond.

[0098] At the same time, the remote centralized control platform 3 will set warning parameters based on factors such as the equipment's usage cycle, workload, and historical fault data. If the equipment's performance exceeds the normal range, the system will automatically generate a warning and remind the administrator to conduct an inspection.

[0099] The remote centralized control platform 3 also has a fault recovery function, which is used to quickly restore the normal operation of the faulty equipment, thereby ensuring that the teaching activities are not affected by equipment failures and reducing interruptions.

[0100] For example, for some common and automatically repairable problems (such as device restart, parameter reset, etc.), the platform can automatically perform recovery operations. For example, if a device stops working due to overload or abnormal interruption, the platform can automatically restart the device and restore it to normal operation. For some minor faults, the remote centralized control platform 3 can send repair commands through remote instructions, such as adjusting the working mode of the device or reconfiguring the device parameters, so that the administrator can perform remote repairs without going to the site.

[0101] In addition, when a device fails, the remote centralized control platform 3 can locate the problem and provide a detailed troubleshooting report to guide the management personnel to perform on-site repairs. If a device fails seriously, the platform will give priority to notifying the management personnel and provide detailed fault information.

[0102] In addition to daily monitoring and fault recovery, the remote control platform 3 is also responsible for equipment maintenance and updates. It can set up regular maintenance plans to remind managers to check and maintain equipment. For example, the air conditioner filter needs to be cleaned regularly, the camera lens needs to be cleaned, etc., and the firmware and software of the IoT devices can be updated remotely to ensure that the performance of the device is always kept in the best state and supports the latest functions and security patches; if a device is outdated or cannot be repaired, the remote control platform 3 can update the management record of the device in time and coordinate the replacement or upgrade of the device.

[0103] In one embodiment disclosed in the present invention, the remote centralized control platform 3 also regularly generates reports on the operating status of IoT devices and provides data analysis functions. For example, the platform regularly generates operating reports on devices to help managers understand the health status, fault frequency, energy consumption data, etc. of the devices, and provide a basis for equipment maintenance and procurement decisions; or, analyze the energy efficiency of each classroom device and provide energy-saving optimization suggestions. For example, the system can analyze the energy consumption of air conditioners and provide suggestions for optimizing temperature adjustment to reduce energy consumption.

[0104] In one embodiment disclosed in the present invention, after receiving the screen control signal input by the user, the remote centralized control platform 3 controls the teaching screens in all target classrooms to play the set information.

[0105] The user inputs a screen control signal through the interactive interface of the remote centralized control platform 3 , and the signal includes information such as specific display content, display time period, specific classroom or screen, etc.

[0106] After receiving the screen control signal input by the user, the remote control platform 3 will analyze and process it, and determine the content to be displayed on the teaching screen of the target classroom according to the user's settings. If the same information needs to be played synchronously in multiple classrooms, the platform will send the information to the screen devices of all relevant classrooms.

[0107] For example, the remote centralized control platform can control the target classroom to display courseware, videos, teaching examples, classroom discipline, exam arrangements, school announcements, activity arrangements, and emergency warnings.

[0108] In one embodiment disclosed in the present invention, the remote centralized control platform 3 can acquire and display multiple video streams in the classroom in real time by communicating with the multimedia equipment (including cameras and teaching screens) in each classroom. For example, if a classroom is equipped with two teaching screens and three cameras, the remote centralized control platform 3 can support the real-time output display of five video streams in the classroom, ensuring that the teaching management personnel can clearly grasp the dynamics in the classroom.

[0109] Teaching management personnel can also switch and view the real-time images of the target classroom at any time through the class inspection mode of the remote centralized control platform 3 without having to go to the scene in person. In addition, the remote centralized control platform 3 supports split-screen display of video streams of multiple classrooms, and management personnel can monitor the situation of multiple classrooms at the same time. In addition, when it is necessary to focus on a certain classroom, the image of the classroom can be zoomed in and focused separately to obtain clearer views and details, thereby improving the supervision effect.
