Description

Technical Field

[0001] This invention relates to the field of intelligent device technology, and more specifically, to an intelligent conference room. Background Technology

[0002] To enhance the functionality and intelligence of traditional conference rooms, existing technologies incorporate various interconnected and controllable intelligent devices, such as computers, monitors, projectors, recording equipment, and video recording equipment. For example, Chinese invention patent application 201380064559.4 discloses a method and system for the automatic preparation and activation of meeting resources. The conference room, meeting area, or meeting resources may be equipped with cameras or other proximity-based sensors to determine when a user enters the meeting area. The camera may perform initial user identification, for example, based on facial or body recognition. The system may then use a second identification technology, such as voice recognition, to verify the user as the meeting organizer. Based on user verification, the system may query the meeting organizer's calendar (or other resources) for meeting information, download relevant meeting presentation files from cloud storage, activate meeting (e.g., screen sharing) software, notify any absent participants that the meeting has started, and begin the presentation on the shared screen. The meeting organizer may then use video and / or sound to control the presentation. All actions can be completed without requiring the meeting organizer to touch anything.

[0003] However, the above invention requires the use of different identification methods to determine the meeting organizer and screen sharing without distinction, making it impossible to distribute different meeting content to different participants; at the same time, it only generates one-way meeting presentation files and cannot obtain real-time decisions on the meeting process or meeting results.

[0004] In existing technologies, identity verification or identification is usually performed in a point-based manner, that is, identification is performed at only one location or repeatedly at multiple locations.

[0005] For example, the method of verifying or identifying a person's identity is to perform user password verification or biometric identification at the location where identification is required. The shortcomings are: on the one hand, there are significant security risks. When the password is stolen or the face is imitated, there is a risk of identity spoofing, whether identification is performed in one location or repeatedly in multiple locations; on the other hand, it requires users to actively output information, resulting in a poor user experience.

[0006] For example, the method for confirming or identifying a person's identity is feature recognition; however, the shortcomings are that the recognition results are prone to breakage, the data source is not entirely reliable, the requirements for recognition technology are high, but the recognition accuracy is low.

[0007] Furthermore, single-point recognition requires high-speed recognition calculations at each point, which places high demands on hardware. As the amount of data increases, the execution efficiency will also decrease. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent conference room that automatically adjusts the desktop size, prepares meeting materials, calls the functional modules of the application system with matching permissions, and adjusts the position of the monitor based on the identification and location information of the participants.

[0009] The technical solution of the present invention is as follows:

[0010] A smart conference room is equipped with several lifting units. When the lifting units are raised, they are used as desktops; when they are lowered, they are used as the floor. The system identifies and obtains the identity information of participating users. Based on the number of participating users, it controls several lifting units to be raised, with the number of raised units matching the number of participating users. Based on the participating users' identity information, it pushes meeting materials matching their identity information to the interactive devices associated with those users, and / or, without the participating users logging in, opens functional modules in the application system corresponding to their identity information's permissions on the interactive devices.

[0011] Preferably, the intelligent conference hall is a flat-bottomed spherical hall. Guide rails are installed along the curvature of the side walls of the spherical hall floor, and several displays are slidably mounted on these rails. The system identifies the position of the currently speaking participant, controls at least one display to slide to face that participant, and displays corresponding meeting materials based on the participant's identity information. When another participant speaks, the system identifies their position, controls at least one display to slide to face them, and displays corresponding meeting materials based on their identity information; and so on.

[0012] Alternatively, when the meeting materials point to other participants, the system identifies the location of those other participants and controls at least one additional display to slide to the location directly facing them.

[0013] As a preferred method, eye tracking is performed on participating users. When a participating user looks at the monitor or interactive device, an eye connection is established by displaying information. Based on the participating users with different identity information, after the eye connection is established, different control plans are executed according to the corresponding identity information. The control plans include the execution mechanism controlled based on the content of the plan.

[0014] A storage opening is provided on the side wall of the spherical hall, and a receiving compartment is provided in communication with the storage opening for storing the monitors; the guide rail extends to the receiving compartment, and when the number of monitors to be used is determined, the corresponding number of monitors slide sequentially from the receiving compartment into the spherical hall along the guide rail.

[0015] Preferably, the guide rail section corresponding to the storage port is a curved guide rail section that protrudes towards the storage port. When the display slides from the storage compartment along the guide rail to the curved guide rail section, the display slides at an angle that is tangent to the curved guide rail section. The display enters the storage port at a corresponding angle. The side of the display facing the storage port enters the storage port first. The display continues to slide along the curved guide rail section. The angle between the display and the side wall of the spherical hall gradually decreases until the display slides out of the curved guide rail section and the display is parallel to the side wall of the spherical hall.

[0016] Preferably, when multiple displays are connected along the guide rails, until the last display slides from the storage opening to be fully inserted, the last display is connected to the two adjacent displays, and all the displays form a ring screen that is connected circumferentially along the inner wall of the spherical hall.

[0017] Preferably, both ends of the display are set as inclined surfaces tilted in the same direction. The tilting direction of the inclined surfaces at both ends of the display is as follows: the end in front of the display in the direction from the receiving compartment to the spherical hall is an outward inclined surface facing the side wall of the spherical hall, and the end in the rear is an inward inclined surface facing the spherical hall.

[0018] When adjacent displays come into contact, the inner inclined surface of the display in front and the outer inclined surface of the display behind form a beveled fit; when all displays are spliced ​​into a panoramic screen, the beveled surfaces of the last display on both sides press against the beveled surfaces at the ends of the two adjacent displays, pushing all displays to form a tight connection.

[0019] Preferably, the storage opening is provided with a receiving door, the shape and size of which are adapted to the shape and size of the storage opening. When the receiving door is closed, the surface of the receiving door forms a smooth spherical surface with the side wall of the spherical hall. Before the display slides in and out of the receiving compartment, the receiving door flips outward and moves horizontally to open the storage opening. After the display slides in and out of the receiving compartment, the receiving door resets and closes the storage opening.

[0020] Preferably, the inner walls of the spherical hall are covered with display screens, the inner walls including side walls and a dome, forming a spherical screen; the dome is provided with several layers of opening and closing mechanisms along the height direction; the size of the openings of the opening and closing mechanisms is adjusted to control the visible range of the dome; when the opening and closing mechanisms are completely closed, a ceiling is formed.

[0021] Preferably, the opening and closing mechanism includes a fixed ring and a rotating ring arranged concentrically, and several adjusting plates disposed between the fixed ring and the rotating ring; the adjusting plates are arranged along the fixed ring or the rotating ring, with one end of the adjusting plate facing the center of the fixed ring or the rotating ring having a triangular tip, and the two side surfaces of the other end of the adjusting plate corresponding to the fixed guide groove of the fixed ring and the rotating guide groove of the rotating ring, respectively, having a protruding passive locking block and a pushing locking block disposed in the fixed guide groove and the rotating guide groove; the number of the fixed guide groove of the fixed ring and the rotating guide groove of the rotating ring are the same as the number of adjusting plates, and the fixed guide groove and the rotating guide groove are evenly distributed in an inclined radial pattern, with the angle of the rotating guide groove of the fixed guide groove being mirror symmetrical.

[0022] Preferably, when the opening and closing mechanism is fully closed, the triangular tips of all the adjusting plates abut against each other; as the rotating ring rotates, the pushing block is pushed by the rotating guide groove and moves from the inner end to the outer end of the rotating guide groove, and the passive block moves synchronously from the inner end to the outer end of the fixed guide groove. Correspondingly, the adjusting plate rotates with the rotation of the rotating ring, and the opening and closing mechanism opens to the corresponding size; conversely, the opening and closing mechanism closes.

[0023] Preferably, the adjustment plate of the spherical hall corresponding to the opening and closing mechanism has a clearance groove, and a strip display screen is provided corresponding to the clearance groove. When the opening and closing mechanism is fully opened, the strip display screen covers the clearance groove.

[0024] Preferably, the strip display screen is positioned below the fixed ring. The strip display screen includes several arc-shaped sub-screens, each connected to a pushing mechanism. The pushing mechanism drives the arc-shaped sub-screens to move back and forth. When the opening and closing mechanism is fully open, it drives the opening and closing mechanism to rise, and the arc-shaped sub-screens rise with the opening and closing mechanism to face the clearance slot. The pushing mechanism drives the arc-shaped sub-screens to move forward to cover the clearance slot. When it is necessary to close the opening and closing mechanism, the pushing mechanism drives the arc-shaped sub-screens to move backward, moving them out of the clearance slot, and drives the opening and closing mechanism to descend to face the clearance slot.

[0025] Preferably, a lifting projector is installed above the spherical hall. When in use, the spherical crown of the spherical hall is moved by the drive mechanism to open the top opening of the spherical hall. The opening and closing mechanism is opened, and the lifting projector is lowered to the set position. The size of the opening of the opening and closing mechanism located below the lifting projector is adapted to the light range of the lifting projector.

[0026] Preferably, the lift projector faces downwards towards the lift unit used as a desktop, and the projection range is adjusted to match the size and shape of the lift unit; the lift projector projects the control interface onto the lift unit used as a desktop, and the participants can operate the control interface through video recognition.

[0027] As a preferred method, a peer-to-peer computing system is used to perform non-specific feature recognition and location recognition of the targets, including participating users, displays, interactive devices, and conference chairs;

[0028] The peer-to-peer computing system includes multiple node devices, and there is no hierarchy among the node devices. Each node device is equipped with a data acquisition device and a computing module. The data acquisition device includes at least one type of sensor, including an image acquisition device, for collecting different types of sensing data. Node devices located at different acquisition positions collect at least one point sample of the target, and the point sample is sensing data of the corresponding sensor type.

[0029] For a given node device, the collected sensing data is processed to obtain result data, which is then propagated to other node devices. Other node devices that receive the result data use it as one of the original data collected, and the result data influences the result data of other node devices. Based on this, without needing to obtain the target's identity information, multiple node devices in the peer-to-peer computing system perform collaborative computing to determine that each unique target is itself, achieving non-specific feature recognition and target location identification.

[0030] As a preferred method, when it is necessary to obtain the target's identity information, an identity information acquisition command is triggered. The identity information acquisition command is used as one of the inputs to participate in the calculation of the result data of the node device. By driving the node device in the peer-to-peer computing system that is connected to the barrier-free data acquisition conditions that can obtain the target's identity information to respond to the corresponding result data, the identity information of the target can be obtained.

[0031] Based on the target's identity information, when it is necessary to obtain meeting content, a meeting content acquisition command is triggered. The meeting content acquisition command is used as one of the inputs to participate in the calculation of the result data of the node device. By driving the node device in the peer-to-peer computing system that is connected to the barrier-free data collection conditions that can obtain meeting content from the office system, the corresponding result data is responded to, thereby realizing the acquisition of meeting content.

[0032] Preferably, the image acquisition device is a plurality of pinhole cameras deployed inside the smart conference hall;

[0033] Alternatively, the image acquisition device may be a telescopic camera device connected to a telescopic mechanism. Driven by the telescopic mechanism, the camera device extends and retracts through a corresponding passage opening on the inner wall of the spherical hall, entering and exiting the hall. The inner wall includes side walls and a dome. A curved screen is installed corresponding to the passage opening. The curved screen is integrated with the telescopic mechanism via a mounting bracket, positioned above or below the telescopic mechanism. When the camera device retracts out of the spherical hall, the mounting bracket is driven to descend or ascend, and the telescopic mechanism and the curved screen descend or ascend synchronously. The curved screen descends or ascends to face the passage opening, and a pushing mechanism moves the curved screen forward to cover the passage opening. When the camera device needs to extend, the pushing mechanism moves the curved screen backward, out of the passage opening, and the mounting bracket is driven to ascend or descend, causing the camera device to ascend or descend to face the passage opening. The telescopic mechanism then pushes the camera device out of the passage opening and into the spherical hall.

[0034] As a preferred option, the human-computer interaction device associated with the participating user is connected to the node device as an access device, and the participating user submits meeting arrangement requirements to the peer-to-peer computing system; each display and interactive device joins the peer-to-peer computing system through one or more node devices; if it is determined based on collaborative computing that the display or interactive device needs to display meeting materials, the current node device will send display control commands to the display or interactive device connected to the current node device according to the calculated result data, and control the display or interactive device to complete the display of meeting materials.

[0035] The beneficial effects of this invention are as follows:

[0036] The intelligent conference hall described in this invention, based on a specially designed structure, enables the adaptation and adjustment of the conference table, the adjustment of the ceiling height, and the adjustment of the number and position of the monitors; furthermore, based on the identification of the identity and location information of the participants, it automatically adjusts various actuators in the intelligent conference hall, including the lifting unit and monitors.

[0037] This invention identifies the identity and location information of participating users, and can prepare meeting materials matching each user's identity and location, and push them to the corresponding interactive device. On the interactive device, it opens the functional module corresponding to the permissions of the application system matched with the user's identity information, so that the user can use it without logging in. This not only makes it convenient for participating users to use, but also prevents unauthorized operations.

[0038] This invention establishes a gaze connection between the participant and the display or interactive device through eye tracking, and determines whether the participant is looking at the display or interactive device. Different control plans are set for participants with different identities or different meeting processes. The control plans include execution mechanisms that are controlled based on the plan content. For example, the execution mechanisms will respond and execute in a targeted manner for participants with different identities or different meeting processes based on the control plans.

[0039] The monitors are positioned by sliding along a guide rail and include a storage compartment for monitors that do not need to be placed inside the smart conference room. The guide rail section corresponding to the storage opening is a curved section protruding towards the storage opening. This specially designed curved guide rail section ensures that monitors enter and exit the storage opening at a predetermined dynamic angle, and that when the last monitor slides fully into the storage opening, it precisely contacts the two adjacent monitors, preventing collisions. The invention also includes a storage compartment door corresponding to the storage opening to ensure the integrity and smoothness of the side walls of the smart conference room.

[0040] This invention features several layers of opening and closing mechanisms along its height; adjusting the opening size of these mechanisms controls the visible range of the dome; when the mechanisms are fully closed, a ceiling is formed, allowing the ceiling height to be controlled as needed. The invention also includes strip displays in the clearance slots for the adjustment plates of the opening and closing mechanisms, ensuring the smooth integrity of the smart conference hall's side walls. Furthermore, the invention provides curved screens in the passageways for telescopic camera devices, again ensuring the smooth integrity of the smart conference hall's side walls.

[0041] This invention utilizes a peer-to-peer computing system for collaborative computation, performing non-specific feature recognition and location identification to achieve identity verification and positioning. In this system, there is no hierarchy among node devices, and no fixed connection paths exist. Each node device only receives the computation results from other nodes and transmits its own results. The detection of events and / or responses from corresponding execution devices (including displays, interactive devices, and various actuators in this invention) do not rely on a single node device for identification and control, but rather on collaborative computation among multiple nodes within the peer-to-peer computing system for joint confirmation. Without requiring specific features or specific identity information, each unique target can be identified as itself, achieving non-specific feature recognition. This invention achieves high accuracy in target identification, identity verification, or event monitoring through non-specific feature recognition, resulting in precise location identification. Furthermore, this invention protects privacy by enabling target identification and identity verification without relying on specific features.

[0042] Based on the target's identity information, this invention triggers a meeting content acquisition command when it is necessary to obtain meeting content. The meeting content acquisition command is used as one of the inputs to participate in the calculation of the result data of the node device. By driving the node device in the peer-to-peer computing system that is connected to the barrier-free data collection conditions that can obtain meeting content from the office system to respond with the corresponding result data, the meeting content can be obtained.

[0043] This invention employs non-specific feature recognition, effectively preventing risks caused by theft or counterfeiting of specific features, thus significantly enhancing security. It utilizes a non-contact, passive method for seamless target identification, greatly improving ease of execution. Based on the aforementioned peer-to-peer computing system, this invention can be easily deployed across coverage areas ranging from hundreds of meters to hundreds of kilometers, making it suitable for various geographical scales.

[0044] In this invention, the execution device responds to the computation results obtained through collaborative computing, resulting in high response efficiency and avoiding illegal responses such as false execution or failure to execute when required due to network attacks. To prevent hijacking, this invention can also use multiple node devices to collaboratively control the execution device, further enhancing its immunity to hijacking attacks.

Detailed Implementation

[0062] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0063] To address the shortcomings of existing technologies, such as limited functionality, low efficiency, and information security, this invention provides an intelligent conference hall. Based on a specially designed structure, it enables adjustments to the conference table, ceiling height, and the number and position of monitors. Furthermore, by identifying the identity and location information of participating users, it automatically adjusts various execution mechanisms within the intelligent conference hall, including lifting units and monitors. This invention also, based on the identification of participating users' identity and location information, can prepare and match meeting materials for each user, and push them to the corresponding interactive device. On the interactive device, it opens the corresponding functional modules in the application system with permissions matching the user's identity information, allowing users to use the system without logging in, thus facilitating user access and preventing unauthorized operations.

[0064] The intelligent conference room described in this invention allows for adjustable size and / or position of the conference table, such as... Figure 1 , Figure 2 , Figure 3 As shown, several lifting units 10 are set on the ground. Normally, each lifting unit 10 has a raised state and a lowered state. When the lifting unit 10 is in the raised state, it serves as a tabletop. When the lifting unit 10 is in the lowered state, it serves as the ground surface. In the intermediate state between the highest raised state and the lowest lowered state, depending on the actual implementation needs, after identifying the participant's identity information to obtain preset height information, or directly performing image recognition to obtain the participant's height information, different height lifting units 10 can be set up to serve as tabletops adapted to participants of different heights. In specific implementation, participants can be guided to sit on the lifting unit 10 at the matched set height.

[0065] In this invention, the identity information of participating users is identified and obtained. Based on the number of participating users (which can be calculated by counting the number of identified and obtained identity information, or by using the peer-to-peer computing system provided by this invention to perform non-specific feature recognition on the target while obtaining the number of participating users in the target), the required size and / or position of the lifting unit 10 used as the desktop is calculated, and several corresponding lifting units 10 are controlled to rise to the raised state. The number of lifting units 10 in the raised state is adapted to the number of participating users. In specific implementation, such as... Figure 1As shown, the lifting unit 10 can be implemented as including a circular lifting unit 101 located at the center, and several concentric annular lifting units 102. That is, the circular lifting unit 101 is located at the center, and the other annular lifting units 102 with different inner diameters are arranged sequentially. Corresponding to different numbers of participants, starting from the circular lifting unit 101, several annular lifting units 102 are set to the raised state, with the circumference of the outermost annular lifting unit 102 sufficient to accommodate all participants. Figure 2 As shown, the lifting units 10 can also be implemented as adjacent units of the same size and shape, or of different sizes and shapes, such as a matrix of lifting units 10; for example... Figure 3 As shown, the lifting units 10 can also be implemented as non-connected units of the same size and shape, or of different sizes and shapes. Other implementations are similar; based on the number of attendees, several lifting units 10, whether connected or non-connected, of the same or different sizes and shapes, are set in a raised state for use by the attendees. A matrix of connected lifting units 10 can also set several lifting units 10 at different positions to a raised state, forming multiple desktops.

[0066] In this invention, based on the participant's identity information, meeting materials matching their identity information are pushed to the interactive device associated with that user, and / or, without the participant logging in, the corresponding functional module in the application system with permissions matching their identity information is opened on the interactive device. Specifically, after the participant is seated, the corresponding interactive device is associated with the participant's identity information, and then meeting materials matching the user's identity are pushed to the associated interactive device. Furthermore, the corresponding functional module in the application system with permissions matching their identity information is opened on the associated interactive device, and the participant can only operate on the opened functional module. At this time, the participant does not need to log in to obtain the functional module with permissions matching their identity information, preventing unauthorized or accidental operations.

[0067] In practical implementation, a monitoring and identification function covering a certain range can be set up to identify and obtain the identity information of participating users before they enter the smart conference hall, and adjust the state of the lifting unit 10 accordingly. After entering the smart conference hall, participating users can take their seats directly, or be guided to designated locations. Based on the seating situation, such as the number of people and the identity information corresponding to the positions, automatic roll call can be performed.

[0068] like Figure 4 , Figure 5As shown, the intelligent conference hall of this invention is a flat-bottomed spherical hall 20. A guide rail 21 (embedded within the sidewall of the spherical hall 20) is provided along the curvature of the floor of the spherical hall 20. Several displays 22 are slidably mounted on the guide rail 21. In this embodiment, the guide rail 21 is embedded below the floor of the spherical hall 20 to maintain the flatness of the floor. The displays 22 are curved displays adapted to the curved surface of the sidewall of the spherical hall 20. The sliding control of the displays 22 on the guide rail 21 can be achieved by a drive trolley or other existing control drive mechanisms, which will not be elaborated further and are not shown in the figure. The displays 22 are connected to the drive trolley or other existing control drive mechanisms via vertical connecting rods.

[0069] To facilitate viewing for participating users who are speaking, this invention identifies the position of the currently speaking user and controls at least one display 22 to slide to face that user, displaying the corresponding meeting materials based on the user's identity information. When the currently speaking user finishes speaking and another user takes over, the location of the other user is identified, and at least one display 22 is controlled to slide to face that user, displaying the corresponding meeting materials based on the other user's identity information; this process continues, allowing the display 22 to be adjusted in real time for each speaking user. The identification of the speaking user's position can be achieved using a voice pickup and recognition method, or by utilizing the peer-to-peer computing system provided by this invention to identify events occurring on the target.

[0070] Furthermore, when the meeting materials (not necessarily the meeting materials matched to the currently speaking user, but also other meeting materials required for the next step of the process or decision based on the speech) point to other participants (such as other participants who are participating at the same time, or participants who need to make a decision), the position of the other participants is identified, and at least one other display 22 is controlled to slide to the position facing the other participants.

[0071] Furthermore, this invention automatically assists in the meeting process. Specifically, eye tracking is performed on the display 22 or interactive device. When a participant looks at the display 22 or interactive device, if a virtual assistant or assistant avatar is displayed on the display 22 or interactive device, a prompt is displayed to establish an eye connection. If the participant looks at the virtual assistant or assistant avatar, a connection countdown is displayed near the virtual assistant or assistant avatar. The participant maintains their gaze until the connection countdown is completed, at which point the eye connection is established. During the eye connection establishment process, if the participant releases their gaze from the display 22 or interactive device before the eye connection is established, the eye connection is canceled until the participant looks at the display 22 or interactive device again.

[0072] In this invention, the intelligent meeting room provides different auxiliary effects for participants with different identities or for different stages of the meeting process. Specifically, based on the participants' different identities, once eye contact is established, different control plans are executed according to their respective identities. These control plans include execution mechanisms associated with the plan content, and these execution mechanisms include various controllable hardware devices and application software installed within the intelligent meeting room. For example, after a participant who is a decision-maker establishes an eye contact, the system controls the speakers in the intelligent meeting room to directly ask questions via voice, monitoring, picking up, and recognizing the responses of the decision-maker. Conversely, after a participant who is not a decision-maker establishes an eye contact, the system controls their personal headset and interactive devices to ask questions in a private manner, which can be done via voice or text.

[0073] In order to accommodate the monitor 22 that is not currently in use, and to reduce the space occupied by the monitor 22 in the spherical hall 20, in this invention, as follows: Figure 4 , Figure 5 , Figure 6 As shown, a storage opening 23 is provided on the side wall of the spherical hall 20, and a receiving compartment 24 communicating with the storage opening 23 is provided for storing the monitors 22. Normally, the receiving compartment 24 is located on the outside of the spherical hall 20 or inside the side wall of the spherical hall 20. Thus, monitors 22 not in use can be stored outside the spherical hall 20 or inside the side wall, reducing the space occupied by the monitors 22 within the spherical hall 20 and minimizing obstruction of the side wall of the spherical hall 20. Especially when the side wall of the spherical dome is covered with a display screen, it is important to avoid obstructing the side wall of the spherical hall 20 as much as possible to avoid affecting the display effect. Specifically, the guide rail 21 extends to the receiving compartment 24. By default, all monitors 22 are stored in the receiving compartment 24. When the number of monitors 22 to be used is determined, the corresponding number of monitors 22 slide sequentially from the receiving compartment 24 into the spherical hall 20 along the guide rail 21 and are positioned at the set initial position.

[0074] To prevent the display 22 from colliding with the side wall of the spherical hall 20 or other displays 22 at the location of the storage opening 23 during its entry and exit from the storage opening 23 into the spherical hall 20, the present invention, such as Figure 6 , Figure 7 , Figure 8As shown, by setting a curved structure for the guide rail segment corresponding to the storage opening 23, the display 22 changes its angle as it slides along the guide rail segment, thereby avoiding the side wall of the spherical hall 20 or other displays 22 and preventing collisions. Specifically, the guide rail segment corresponding to the storage opening 23 is a curved guide rail segment protruding towards the storage opening 23. When the display 22 slides from the receiving compartment 24 along the guide rail 21 to the curved guide rail segment, the display 22 slides at an angle that remains tangent to the curved guide rail segment. The display 22 enters the storage opening 23 at a corresponding angle, with the side of the display 22 facing the storage opening 23 entering first. The display 22 continues to slide along the curved guide rail segment, and the angle between the display 22 and the side wall of the spherical hall 20 gradually decreases until the display 22 slides out of the curved guide rail segment, at which point the display 22 is parallel to the side wall of the spherical hall 20. In practice, when the display 22 slides out of the curved guide rail section 211 and fully enters the spherical hall 20, there is still a certain angle between the display 22 and the side wall of the spherical hall 20. Since there is a certain distance between the display 22 and the side wall of the spherical hall 20, after the display 22 slides along the curved guide rail section 211 until it is fully inside the spherical hall 20, it continues to slide along the curved guide rail section 211 until it slides out of the curved guide rail section 211, at which point the display 22 is parallel to the side wall of the spherical hall 20. Specifically, when all the displays 22 enter the spherical hall 20, adjacent displays 22 connect in pairs to form a ring screen. In this invention, the curvature requirement for the curved guide rail section is: when multiple displays 22 connect along the guide rail 21, until the last display 22 slides from the receiving opening 23 to be fully inside, the last display 22 connects exactly with the two adjacent displays 22, and all the displays 22 form a ring screen that is circumferentially connected along the inner wall of the spherical hall 20. That is, when the last display 22 has not yet slid out of the receiving compartment 24, the remaining displays 22 are already located on the guide rail 21 of the spherical hall 20 and are connected in pairs. The space between the first display 22 to enter the spherical hall 20 and the second-to-last display 22 to enter the spherical hall 20 (the only display 22 currently in the receiving compartment 24 is the last display 22) is just enough to accommodate one display 22. As the last display 22 slides into the spherical hall 20 along the curved guide rail segment 211, the display 22 enters at a certain angle to the side wall of the spherical hall 20, and the angle decreases as it slides. When the last display 22 slides out of the curved guide rail segment and fully enters the spherical hall 20, the display 22 is parallel to the side wall of the spherical hall 20, and the last display 22 is exactly connected to the first and second-to-last displays to enter the spherical hall 20 without colliding. In practice, the curvature of the curved guide rail segment can be calculated using conventional mathematical methods based on the size of the spherical hall 20 (which determines the curvature of the side walls), the size and curvature of the display 22, and the height of the display 22 (i.e., the guide rail 21) in the spherical hall 20.

[0075] To prevent damage caused by hard compression during the contact process of the display 22, and to enable the display 22 to adaptively fine-tune and achieve a tight connection during the contact process, in this invention, both ends of the display 22 are respectively set as inclined surfaces in the same direction. The inclination direction of the inclined surfaces at both ends of the display 22 is as follows: the end located in front of the display 22 in the direction from the receiving compartment to the spherical hall is an outward inclined surface facing the side wall of the spherical hall, and the end located in the rear is an inward inclined surface facing the spherical hall.

[0076] When adjacent displays 22 come into contact, the inner inclined surface of the front display 22 and the outer inclined surface of the rear display 22 form a beveled fit, which can effectively prevent hard squeezing between the displays 22. In particular, excessive sliding of the displays 22 can cause excessive squeezing between the displays 22, resulting in cracks at the edges and corners of the displays 22.

[0077] When all the displays 22 are spliced ​​into a panoramic screen, the inclined surfaces of the last display 22 on both sides press against the inclined surfaces at both ends of the two adjacent displays 22, pushing all the displays 22 to form a tight connection. Based on the inclined surface cooperation between adjacent displays 22, even if the space between the first display 22 entering the spherical hall 20 and the second-to-last display 22 entering the spherical hall 20 is less than the width of one display 22 because the displays 22 already in the spherical hall 20 are not tightly connected, when the last display 22 tilts into the spherical hall 20, as the angle of the last display 22 changes, the two ends of the last display 22 form an inclined surface cooperation with one end of the two adjacent displays 22. Through the pressure of the inclined surface cooperation, the two adjacent displays 22 are pushed to move in the opposite direction, and then the other displays 22 are pushed in turn, so that the position of all the displays 22 is adjusted, and finally a tight connection is achieved, avoiding gaps in the panoramic screen formed by multiple displays 22, which would affect the display effect.

[0078] To improve the space utilization of the storage compartment 24 and accommodate more displays 22 in a smaller space, in this embodiment, as follows: Figure 6As shown, the receiving compartment 24 is equipped with multiple guide rails 21, and the guide rail 21 into which the display 22 enters is selected by the track switching mechanism 27. Specifically, the track switching mechanism 27 is equipped with a first direction track 271 and a second direction track 272. Correspondingly, a first inner guide rail 241 and a second inner guide rail 242 are provided in the receiving compartment 24. When the first direction track 271 or the second direction track 272 is connected to the curved guide rail segment 211, the first inner guide rail 241 and the second inner guide rail 242 are connected to the first direction track 271 and the second direction track 272, respectively. During use, by controlling the sliding of the track switching mechanism 27, the curved guide rail segment 211 is switched to be connected to the first direction track 271 or the second direction track 272, thereby controlling the first direction track 271 or the second direction track 272 to be connected to the first inner guide rail 241 or the second inner guide rail 242, and finally controlling the display 22 to enter the first inner guide rail 241 or the second inner guide rail 242 for storage. Based on this, the display 22 can be arranged in multiple rows within the storage compartment 24.

[0079] To ensure the integrity and smoothness of the sidewalls of the spherical hall 20, in this invention, as follows: Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the storage opening 23 is equipped with a receiving door 25, the shape and size of which are adapted to the shape and size of the storage opening 23. In this invention, a guide rail 21 is adapted to be embedded in the ground, and both the storage opening 23 and the receiving door 25 extend to the ground, with their height and width meeting the size requirements of the display 24 and the space requirements for sliding in and out. When the receiving door 25 is closed, its surface forms a smooth spherical surface with the side wall of the spherical hall 20. Before the display 22 slides in and out of the receiving compartment 24, the receiving door 25 flips and moves outward, that is, it flips towards the receiving compartment 24 at a certain angle while simultaneously moving (e.g., the outer wall of the spherical hall 20 and the back of the receiving door 25 are connected by a curved connecting rod 26 that rotates at one end, and the curved connecting rod 26 is fixedly connected to the back of the receiving door 25). During the rotation of the curved connecting rod 26, the receiving door 25 can be flipped and moved simultaneously, thereby opening the storage opening 23. After the display 22 slides in and out of the receiving compartment 24, the receiving door 25 flips and moves in the opposite direction, the receiving door 25 returns to its original position, and the storage opening 23 is closed.

[0080] To form a dome-shaped screen in the spherical hall 20 and achieve the largest possible display area, in this invention, the inner walls of the spherical hall 20 are covered with display screens. These inner walls include side walls and a dome, forming a dome. In specific implementation, the doors of the spherical hall 20 are also covered with display screens to ensure the integrity of the dome when the doors are closed. Figure 4 , Figure 5As shown, the dome is provided with several layers of opening and closing mechanisms 30 along the height direction; adjusting the opening size of the opening and closing mechanism 30 controls the visible range of the dome; when the opening and closing mechanism 30 is completely closed, a ceiling is formed, that is, if a certain layer of opening and closing mechanism 30 is completely closed, that layer of opening and closing mechanism 30 is considered to form a ceiling, thus determining the ceiling height of the spherical hall 20.

[0081] Among them, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 The opening and closing mechanism 30 shown includes a fixed ring 31 and a rotating ring 32 arranged concentrically, and a plurality of adjusting plates 33 disposed between the fixed ring 31 and the rotating ring 32. The adjusting plates 33 are arranged along the fixed ring 31 or the rotating ring 32. One end of the adjusting plate 33 facing the center of the fixed ring 31 or the rotating ring 32 is a triangular tip. The two side surfaces of the other end of the adjusting plate 33 correspond to the fixed guide groove 311 of the fixed ring 31 and the rotating guide groove 321 of the rotating ring 32, respectively. They are provided with a passive locking block 331 and a pushing locking block 332 protruding and disposed in the fixed guide groove 311 and the rotating guide groove 321, respectively. The number of fixed guide grooves 311 of the fixed ring 31 and the number of rotating guide grooves 321 of the rotating ring 32 are the same as the number of adjusting plates 33. The fixed guide grooves 311 and the rotating guide grooves 321 are evenly distributed and arranged in an inclined radial pattern. The angle of the rotating guide grooves 321 of the fixed guide groove 311 is mirror symmetrical.

[0082] When the opening and closing mechanism 30 is fully closed, the triangular tips of all the adjusting plates 33 abut against each other. During operation, the fixed ring 31 remains stationary, while the rotating ring 32 rotates, causing the adjusting plates 33 to slide and rotate, thus gradually opening from the center position. When each layer of the opening and closing mechanism 30 is fully open, the opening is larger than the cross-sectional size of the spherical hall 20 at that location. Specifically, as the rotating ring 32 rotates (driven by other drive structures, which will not be elaborated further and are not shown in the figure), the pushing block 332 is pushed by the rotating guide groove 321 and moves along the rotating guide groove 321 from the inner end to the outer end. The passive block 331 moves synchronously along the inner end of the fixed guide groove 311 to the outer end. Correspondingly, the adjusting plate 33 rotates with the rotation of the rotating ring 32, and the opening and closing mechanism 30 opens to the corresponding size; conversely, the opening and closing mechanism 30 closes.

[0083] In order to ensure that the spherical hall 20 can achieve a display effect similar to a dome screen even when the opening and closing mechanism 30 is closed, in this invention, the downward-facing side of the adjustment plate 33 is covered with a liquid crystal display film, which works together with the display screen on the inner wall of the spherical hall 20 for display.

[0084] To avoid the opening and closing mechanism 30 affecting the integrity of the dome screen, in this invention, as... Figure 13 , Figure 14 , Figure 15 As shown, the spherical hall 20 has a clearance groove 202 on the adjusting plate 33 corresponding to the opening and closing mechanism 30. Under normal circumstances, the fixed ring 31 and the rotating ring 32 are located outside the inner wall of the spherical hall 20, that is, they do not extend into the spherical hall 20 and do not obstruct the dome screen. Only the adjusting plate 33 enters and exits the spherical hall 20 through the clearance groove 202. In a specific implementation, a strip display screen 40 is provided corresponding to the clearance groove 202. When the opening and closing mechanism 30 is fully opened, the strip display screen 40 covers the clearance groove 202. Specifically, the strip display screen 40 is positioned below the fixed ring 31. The strip display screen 40 includes several arc sub-screens 41, each connected to a pushing mechanism. The pushing mechanism is also integrated with the fixed ring 31, driving the arc sub-screens 41 to move back and forth. When the opening and closing mechanism 30 is fully open, it is driven to rise (driven by a conventional driving structure, which will not be described in detail or shown in the figure). The arc sub-screens 41 rise with the opening and closing mechanism 30 to face the clearance slot 202. The pushing mechanism drives the arc sub-screens 41 forward to cover the clearance slot 202. All the arc sub-screens 41 form a strip display screen 40, which displays together with the display screen on the inner wall of the spherical hall 20. When it is necessary to close the opening and closing mechanism 30, the pushing mechanism drives the arc sub-screens 41 to move backward, moving them out of the clearance slot 202, and the opening and closing mechanism 30 descends to face the clearance slot 202.

[0085] like Figure 4 , Figure 5As shown, a lifting projector 50 is installed above the spherical hall 20. In use, the spherical crown 201 of the spherical hall 20 moves via a drive mechanism (a conventional drive mechanism, not described further, and not shown in the figure), opening the top opening of the spherical hall 20. The opening and closing mechanism 30 opens, and the lifting projector 50 descends to a set position (driven by a conventional lifting structure, not described further, and not shown in the figure). The opening size of the opening and closing mechanism 30 below the lifting projector 50 is adapted to the light range of the lifting projector 50. Since the size of the adjustment plate 33 of the opening and closing mechanism 30 is adjustable, it can accommodate lifting projectors 50 of different heights (different heights of lifting projectors 50 correspond to different projection range requirements). Normally, the lifting projector 50 does not descend below the position of the opening and closing mechanism 30. All opening and closing mechanisms 30 are opened to a minimum without obstructing the light from the lifting projector 50, thus visually obstructing the lifting projector 50 and achieving the purpose of hiding it. Specifically, opening and closing mechanisms 30 at different heights correspond to different light ranges of the lifting projector 50. That is, the closer the opening and closing mechanism is to the lifting projector 50, the smaller the corresponding light range and the smaller the opening of the opening and closing mechanism 30; conversely, the closer it is to the lifting projector 50, the larger the light range. In use, based on known parameters such as the size of the projection range, the distance between the lifting projector 50 and the lifting unit 10 used as a tabletop, the height of all opening and closing mechanisms 30 from the ground, and the distance between the lifting unit 10 used as a tabletop and the ground, the light range at each position from the lifting projector 50 to the lifting unit 10 used as a tabletop can be calculated, and thus the minimum opening size corresponding to each opening and closing mechanism 30 can be calculated.

[0086] The lifting projector 50 faces downwards and is directly opposite the lifting unit 10 used as a desktop, and the projection range is adjusted to match the size and shape of the lifting unit 10; the lifting projector 50 projects the control interface onto the lifting unit 10 used as a desktop, and the participants can operate the control interface through video recognition. Specifically, to facilitate simple and accurate operation of the projected interface, this invention employs multiple image acquisition devices at different locations to acquire images of the lifting unit 10 used as a desktop and the hands of the participating users. Using the acquired images containing the lifting unit 10, the size and position of the plane formed by the lifting unit 10 are identified, and the lifting projector 50 is controlled to project an interface matching the size of the plane. Using the acquired images containing the participating users' hands, image recognition technology is used to identify hand gestures. Furthermore, different control schemes are preset for participating users with different identities. For example, for the current participating user, different gestures correspond to different operations on the current control interface. For another control interface, the same different gestures can correspond to different operations, thus forming an N×M system, where N is the number of control interfaces and M is the number of gestures. When users operate the interface, they do not need to extend their hands above the interface to perform direct or indirect actions. This effectively prevents accidental touches and reduces the complexity of action recognition. Users can place their hands beside them and perform different gestures corresponding to different operations on the interface. Different users can be customized with their own gestures or established relationships between gestures and operations, thus avoiding strict adherence to the same set of rules.

[0087] In this invention, the lifting unit 10 is embedded with a wireless charging transmitter, and at least one wireless charging receiver is located at the bottom of the conference chair. When the receiver at the bottom of the conference chair overlaps with the transmitter of the lifting unit 10, wireless charging can be performed, supplying power to the electrical devices installed on the conference chair via wireless charging. These electrical devices include, but are not limited to, the interactive device, wireless communication device, audio acquisition device, and image acquisition device. The wireless communication device is connected to the interactive device, microphone, and image acquisition device. For energy saving, this invention identifies the position of the conference chair and then activates the corresponding transmitter to perform wireless charging. If the identification result indicates that a conference chair is not located at the position of a transmitter, that transmitter is not activated.

[0088] In this invention, the image acquisition device is a plurality of pinhole cameras deployed inside the smart conference hall;

[0089] Or, such as Figure 16 As shown, the image acquisition device is a telescopic camera device 60. The camera device 60 is connected to a telescopic mechanism and, driven by the telescopic mechanism, extends and retracts through the corresponding channel hole 203 on the inner wall of the spherical hall 20, entering and exiting the spherical hall 20. The inner wall includes side walls and a dome. To ensure the integrity and smoothness of the inner wall of the spherical hall 20, an arc-shaped screen is provided corresponding to the channel hole 203. The arc-shaped screen is integrated with the telescopic mechanism via a mounting bracket 61 (a conventional telescopic mechanism, not described in detail, and not shown in the figure). The arc-shaped screen is located above or below the telescopic mechanism. When the camera device 60 retracts out of the spherical hall 20, it drives the mounting bracket 61 to descend or ascend (driven by a conventional drive structure, not described in detail, and not shown in the figure). The telescopic mechanism and the arc-shaped screen descend or ascend synchronously. When the arc-shaped screen descends or ascends to face the channel hole 203, the pushing mechanism moves the arc-shaped screen forward to cover the channel hole 203. The arc-shaped screen and the display screen of the spherical hall 20 then display together. When the camera device 60 needs to be extended, the pushing mechanism drives the curved screen to move backward, moving out of the channel hole 203, driving the mounting bracket 61 to rise or fall, and the camera device 60 rises or falls to face the channel hole 203. The telescopic mechanism pushes the camera device 60 out of the channel hole 203 and into the spherical hall 20.

[0090] In practical implementation, traditional single-point identification methods can be used to identify participating users at designated locations, achieving the purpose of identity verification linked to location information. Alternatively, the peer-to-peer computing system provided by this invention can be used for non-specific feature-based identity identification. The peer-to-peer computing system of this invention is based on collaborative computing, does not rely on single-point identification, and distributes all computing functions across the peer-to-peer computing system, reducing the hardware and software requirements of single-point computing, resulting in high execution efficiency and significantly improved anti-attack capabilities. The system maintains a relatively symmetrical information state among node devices, making it immune to illegal data tampering. Even if a single node device is physically compromised and its transmitted data is tampered with, the tampering does not affect the calculation results of the peer-to-peer computing system because the computation of the peer-to-peer computing system involves highly redundant and complex calculations and multi-dimensional verification. Furthermore, it can quickly locate the faulty and tampered node device, ensuring the reliability of the calculation results of the peer-to-peer computing system. Therefore, it can resolve the contradiction between data sharing and information security between departments.

[0091] The result data transmitted between node devices can be the processing result of information rather than the information itself. Therefore, the raw data collected (i.e., perceived data) does not need to be stored. Node devices only receive the calculation results output by other node devices and send out their own calculation results. The amount of information contained in a single calculation result is insufficient to reconstruct any event or target information. A definite result can only be obtained by joint calculation of the calculation results of the entire peer-to-peer computing system, multi-dimensional data matrix elements, and physical space and facility correspondence. The collaborative calculation has less dependence on the information transmitted by a few node devices, thus fundamentally changing the nature of traditional information technology's single-point security sensitivity.

[0092] In this invention, the acquisition of the identity information and location information of participating users can be achieved through collaborative computing using the peer-to-peer computing system provided by this invention. Specifically, this invention utilizes the peer-to-peer computing system to perform non-specific feature recognition and location recognition of targets, including but not limited to all participating users, displays, interactive devices, and conference chairs. The term "non-specific feature recognition" differs from the common understanding of "recognition" in a strict conceptual definition. Commonly, "recognition" refers to identifying the concrete form or specific identity information of a target, such as who it is (including name, specific information indicating the target's identity), or what it is (e.g., a car, a person). However, the "recognition" in this invention refers to identifying each unique target (i.e., participating user, display, interactive device, conference chair) as itself; that is, for a given object to be identified, its existence is unique. After achieving "non-specific feature recognition," this invention determines that the object to be identified (i.e., the target that has not been identified or confirmed) is itself, and not other objects to be identified. The result of "non-specific feature recognition" does not require determining the specific characteristics of the object to be identified, nor does it require determining the identity information or concrete form of the object to be identified. For example, if a person is considered object A to be verified, and an object is considered object B to be verified, then after implementing "non-specific feature recognition," it is not necessary to identify whether object A is a person or what their specific identity is, nor is it necessary to identify whether object B is an object or what kind of object it is; rather, it is necessary to determine that object A is object A itself, and object B is object B itself. Then, corresponding services or controls can be provided for object A or object B.

[0093] The peer-to-peer computing system comprises multiple node devices, all without a hierarchy, forming a decentralized network and computing architecture. Unlike traditional single-point aggregation computing models, the data transmission direction between node devices in this invention does not have a fixed, predetermined path relationship. In the peer-to-peer computing system described in this invention, a particular node device processes the collected raw data to obtain result data, and then propagates the result data to other node devices. Other node devices that receive the result data use it as one of their collected raw data sets, thus influencing the result data of other node devices. For ease of description, the aforementioned "particular node device" is referred to as the "current node device," and the "other node devices" are referred to as "subsequent node devices." One aspect of this influence is that the result data obtained by subsequent node devices is not entirely determined by their own collected raw data, but rather by the result data output by the current node device. Specifically, the result data output by the current node device may alter the data processing model and parameters used by subsequent node devices to calculate the result data, thereby affecting the result data of subsequent node devices. For example, if the output data of the current node device is correlated with the raw data collected by subsequent node devices, it is necessary to consider the impact of the output data of the current node device on the accuracy of the output data of the subsequent node devices. Specifically, for the perception of a specific target, if the result data is calculated based solely on the raw data collected by subsequent node devices, it can only reflect the real-time (including real-time location and time) single-point result judgment of the target within the perception range of the subsequent node devices. However, the output data of the current node device reflects the direct perception data and result judgment of the target at other locations and at other times, or other indirectly related perception data and result judgments, which helps to improve the accuracy and comprehensiveness of the result data of the subsequent node devices, including superimposed calculations of the same dimension and correlation references of different dimensions.

[0094] Because there is no master-slave relationship between nodes in a peer-to-peer computing system, point-to-point transmission is possible. Therefore, for a given calculation result corresponding to a specific perceived data point of a target, as reflected in the output data of one node, the information is relatively symmetrical among other nodes receiving that result data. Other nodes use the received result data as input, combining it with their own sensor data to calculate their own result data. Their own result data naturally encompasses both the received result data and the information reflected by their own sensors, and is transmitted to other nodes in the next layer. Thus, for a specific perceived data point of a target, information is relatively symmetrical across all nodes. This prevents the impact of tampering or falsification of the calculation process and results of a single node on the result data. It also serves as a means to detect faulty, tampered, or non-compliant node devices. This fundamentally solves the inherent hidden dangers of traditional information technology, namely, the false, falsified, and erroneous information caused by information asymmetry, which becomes a point of entry for fraud and cyberattacks. It also addresses the problems of poor accuracy, excessive time consumption, low credibility, and poor responsiveness in complex integrated applications. Therefore, it can truly become the information infrastructure for comprehensive management of large areas and the infrastructure for the digital economy. Unlike blockchain technology, which relies on independent computation by each node to determine the result and emphasizes the preservation of original data, this invention focuses on peer-to-peer collaborative computation among node devices. Through this collaborative computation, each node device can adjust its own data processing model (i.e., the algorithm for calculating the result data) and parameters when processing data. This adjustment is a feedback mechanism from all node devices, transforming the computation of all node devices into a unified whole. Instead of individual nodes performing calculations independently, all node devices collaboratively complete the computation. The adjustments to the node device's data processing model are objectively real and will impact subsequent data processing iterations.

[0095] Node devices are equipped with data acquisition devices (in specific implementations, these may include one or more of the following: image acquisition devices, audio acquisition devices, temperature measurement devices, vibration frequency sensing devices, lidar, chemical sensors, and electromagnetic induction devices) and a computing module. The data acquisition devices include various types of sensors, including image acquisition devices and audio acquisition devices, used to collect different types of corresponding sensor data. The computing module calculates the result data based on a data processing model. Node devices located at different acquisition positions (i.e., at different physical installation locations) collect at least one point sample of the target; the point sample is sensor data corresponding to the sensor type. Based on this, without needing to obtain the target's identity information, multiple node devices in the peer-to-peer computing system perform collaborative calculations to determine that each unique target is itself, achieving non-specific feature recognition; and, furthermore, achieving target location recognition.

[0096] Specifically, taking a given node device as the current node device, and considering the data transmission between its preceding and subsequent node devices (in this invention, "preceding node device" and "subsequent node device" only describe their sequential relationship with the current node device in the current calculation and data transmission process, and do not imply any necessary sequential or priority relationship between them), the current node device receives the result data output by other node devices (including preceding node devices), and subsequent node devices receive the result data output by other node devices (including the current node device). For the current node device, the collected sensing data is combined with the result data from other node devices (including preceding node devices) to calculate the result data of the current node device, and this result data is sent to other node devices (including subsequent node devices). Similarly, the working process of subsequent node devices is the same as that of the current node device, and preceding node devices also receive the result data from the preceding node devices of their predecessors and perform the same working process as the current node device; that is, the node devices in the peer-to-peer computing system perform the same working process. Furthermore, the node devices in the peer-to-peer computing system perform collaborative calculations as sensing data is collected and result data is calculated. In this process, the output data of a certain node device is only received and used as input by the subsequent layer of node devices, and the output data of the subsequent layer of node devices will cover the output data of the preceding layer of node devices (including the aforementioned node device).

[0097] In a peer-to-peer computing system, all events are processed synchronously, and it is not necessarily necessary to explicitly produce staged outputs such as what event was discovered or what the specific content of the event is. In a peer-to-peer computing system, only the perception of sensors and the corresponding execution devices (in this invention, including displays, interactive devices, and various execution mechanisms) are clearly defined. All other intermediate processes are processed simultaneously through collaborative computing. That is, during the operation of this invention, the intermediate process of event discovery is imperceptible. As collaborative computing proceeds and the result data of the node devices is obtained, the corresponding execution devices automatically respond and execute.

[0098] To further ensure the trustworthiness of the data source and computation process, in this invention, all node devices encrypt their computational results based on an encrypted consensus mechanism, obtaining encrypted results, which are then sent to other node devices. The encrypted consensus mechanism includes one or more mechanisms, with different mechanisms corresponding to changes in the encryption algorithm structure and parameters of the node devices.

[0099] Node devices communicate using standard-sized data packets (i.e., result data or calculation results). In this invention, the node devices in the peer-to-peer computing system are similar to human neurons. Just as each neuron does not transmit specific data directly describing external events, the node devices do not output raw data. Instead, they process the raw data acquired by connected sensors and data acquisition devices into standard-sized data packets (i.e., result data or calculation results, similar to nerve impulses in neurons) based on their own data processing models (similar to the biological characteristics of nerve cells). The information contained in a single data packet is insufficient to reconstruct any event or target information. A definite result can only be obtained through collaborative computation involving the calculation results across the entire peer-to-peer computing system, multi-dimensional data matrix elements, and the correspondence between physical space and facilities. Collaborative computation has little dependence on the data output by a few node devices, and it simultaneously processes all requests received or initiated by all node devices. It is a collaborative verification computation of highly multi-dimensional related information, thus fundamentally changing the traditional single-point security sensitivity of information systems.

[0100] To ensure data integrity and the effective execution of collaborative computing, this invention deploys a QoS mechanism in the peer-to-peer computing system. The QoS mechanism prioritizes ensuring the transmission quality of result data between node devices.

[0101] In practical implementation, the peer-to-peer computing system can be networked using one or more combinations of 4G, 5G, or MESH modes to suit different application scenarios. The optimal solution is achieved by considering factors such as feasibility and cost. The MESH mode is based on the LTE standard, communicating at the LTE physical layer. Data is carried by a customized frame structure, and interaction is performed using a dedicated wireless communication protocol. Customizing the frame structure to suit peer-to-peer computing and employing a proprietary wireless communication protocol developed for urban cluster peer-to-peer computing further enhances its security and reliability. Furthermore, the wireless algorithm is fully adapted to the multipath channel environment controlled by a consensus mechanism required for peer-to-peer computing, achieving communication distances of 100 meters to 10 kilometers within cities and 120 kilometers in the field using omnidirectional antennas. In this embodiment, the Mesh network communication distance is 50-150 meters between indoor nodes and 50 meters to 120 kilometers between outdoor nodes, with each node capable of connecting to 65,535 nodes. In addition, when networking in 4G and 5G modes, there is no limit to the communication distance, and the number of node devices that can be connected depends on the computing power of the computing chip and the communication latency.

[0102] In a peer-to-peer computing system, for a specific point sample of an object to be identified, the result data transmitted from the node device that collected the point sample to other node devices allows subsequent node devices to adjust their perceptual attention based on the features of that point sample (it is not necessary for the result data to contain the features of that point sample, but rather that the features of that point sample participate in the computation of the preceding node device, so that the result data of the preceding node device can be used as input to the data processing model of the subsequent node device, allowing the subsequent node device's data processing model to achieve the effect of adjusting perceptual attention during computation); or, the features of that point sample can be reported for subsequent node devices to adjust their perceptual attention (the features of that point sample are directly described in the result data). If other subsequent node devices do not detect the features of that point sample, but can determine from the features of other point samples that the undetected features of that point sample still belong to the object to be identified, then the features of that undetected point sample are continued to be described in the result data of the current node device and transmitted to other node devices. For example, if a preceding node device senses the color of an object A to be identified, but the current node device does not sense the color of the object A to be identified, but it can be determined from the sensing data of other node devices that there is another object A to be identified besides other objects to be identified, then the color of the object A to be identified that has not been sensed will still be represented in the result data of the current node device.

[0103] In this embodiment, the method for reporting the features of the point sample for subsequent node devices to adjust the perceptual attention is as follows: adjusting the parameters of the data processing model of the subsequent node device based on the features of the point sample provided by the preceding node device, so that the subsequent node device can improve the computing power of the point sample to identify its features; or, the subsequent node device uses the perceptual attention model to match the features of the received point sample to adjust the computing power.

[0104] The “feature” mentioned above has a different meaning from the “feature recognition” in the prior art. The “feature recognition” in the prior art usually refers to information that can determine the identity of a target, while the “feature” in this invention represents a kind of perceived data belonging to the object to be identified, such as coordinates, colors belonging to the object to be identified, etc. The “non-specific feature recognition” of the object to be identified cannot be directly completed by the “feature” perceived by a single point.

[0105] In this embodiment, the method for reporting the features of the point sample for subsequent node devices to adjust the perceptual attention is as follows: based on the result data expressing the features of the point sample provided by the preceding node device (in this invention, the features of the point sample are usually not provided themselves, but expressed in the result data), or the features of the point sample (i.e. the features of the point sample itself), the parameters of the data processing model of the subsequent node device are adjusted so that the subsequent node device can improve the computing power of the point sample to identify its features; or, the subsequent node device uses the perceptual attention model to match the features of the received point sample or the result data expressing the features of the point sample to adjust the computing power.

[0106] When a node device processes the output data from several preceding node devices, based on the data processing model, if the objects to be identified described by several preceding node devices can be determined to be the same target through certain common point sample features, the point sample features and other information described by each node device are merged into the same target. For example, point sample features in physical space that almost completely overlap at the same time can be determined to be the same target.

[0107] When the result data received by a node device indicates that the flag used by the current node device to identify the object to be identified before the current reception of result data is different from the flags used by other node devices to identify the object to be identified, and the flags assigned to the object by other node devices have been updated, then the flag used by the current node device to identify the object to be identified before the current reception of result data is converted. Specifically, the method for converting the flag used by the current node device to identify the object to be identified before the current reception of result data is as follows:

[0108] The flag used by the current node device to identify the object to be identified before the current reception of result data is replaced with the latest flag assigned to the object by other node devices; this is a simpler implementation method provided by the present invention.

[0109] Alternatively, the conversion relationship between the flag used by the current node device to identify the object to be identified before the current receiving result data and the updated flags assigned to the object by other node devices can be recorded, and the conversion can be performed when the current node device's current receiving result data needs to be referenced; this is a relatively complex implementation method provided by the present invention.

[0110] Alternatively, the node device can deploy a conversion model to perform corresponding conversions on the labels of multiple objects to be identified based on the input raw data or result data; this is a more complex implementation provided by the present invention.

[0111] In this invention, in order to improve the effectiveness of "non-specific feature recognition", for one or more point samples collected successively by node devices at different collection locations, if the feature values ​​of one or more point samples at different collection locations meet the preset similarity conditions or are determined by a specific model to have a correlation threshold, and are unique at each collection location, then it is determined that the point samples at different collection locations are correlated.

[0112] On the other hand, for one or more point samples collected simultaneously by node devices at different collection locations, if the node devices at different collection locations collect data on the same spatial field, and there is only one object to be identified in the spatial field, or the collected point sample can correctly point to one of the multiple objects to be identified, then for a certain object to be identified, one or more point samples collected by node devices at different collection locations are correlated.

[0113] In this invention, the data acquisition device of the node device includes one or more combinations of an image acquisition device, an electromagnetic induction device, a temperature measurement device, and a vibration frequency sensing device, and a lidar. The data acquired by the aforementioned devices (i.e., one or more combinations of the image acquisition device, electromagnetic induction device, temperature measurement device, and vibration frequency sensing device) and the three-dimensional point cloud acquired by the lidar, or the point cloud generated from images acquired by multiple image acquisition devices, are jointly calculated to obtain three-dimensional points with data. The image color, contour, lines, reflectivity, motion trend, electromagnetic characteristics, temperature, temperature change trend, vibration frequency, and vibration frequency change trend based on two-dimensional perception are used as additional attributes of the corresponding three-dimensional points to constitute an attributed three-dimensional point cloud. Combining electromagnetic induction, temperature patterns, vibration frequency change characteristics, motion correlation (different motion correlations exhibited by different materials such as ropes and fabrics), and reflectivity, the correspondence between each region of the attributed three-dimensional point cloud and each part or related part of the 3D appearance of the object to be identified is determined. This embodiment utilizes the attributes and correlations of attributed 3D point clouds to determine the relationships between points, the correspondence between the regions to which each related point belongs and each part or related part of the 3D appearance of the object to be identified, and can more accurately determine the point sample features belonging to the object to be identified, thereby improving the efficiency and accuracy of "non-specific feature recognition".

[0114] In the process of "non-specific feature recognition," this invention can also acquire the identity information of the object to be identified when necessary. Specifically, when it is determined that the identity information of the object to be identified needs to be acquired, an identity information acquisition command is triggered. This command is used as one of the inputs in the calculation of the result data of the node device. By driving the node device in the peer-to-peer computing system, which is connected to the barrier-free data acquisition conditions capable of obtaining the identity information of the object to be identified, to respond with the corresponding result data, the identity information of the object to be identified is acquired. In this invention, based on the target's identity information, when it is necessary to acquire meeting content, a meeting content acquisition command is triggered. This command is used as one of the inputs in the calculation of the result data of the node device. By driving the node device in the peer-to-peer computing system, which is connected to the barrier-free data acquisition conditions capable of obtaining meeting content from the office system, to respond with the corresponding result data, the meeting content is acquired.

[0115] The acquisition of identity information and meeting content is also a result of collaborative computation. That is, the determination that identity information and meeting content need to be acquired triggers the acquisition of these information, rather than through a specific request command. Based on this invention, if permission calculation is triggered by a request command, in most cases, it can be completed without acquiring identity information. Only in rare cases, when it is found that permission calculation cannot be completed without acquiring identity information, will a determination requiring the acquisition of identity information be generated based on implementation needs. For example, if collaborative computation reveals that a person's identity information exists in several location-based QR code registration systems, several location-based express delivery registration systems, or several location-based consumption registration systems, and prior authorization from the person or legal access to query this information is obtained, then the peer-to-peer computing system can drive node devices connected to these systems in an accessible data collection manner. The relevant information obtained is sent to the peer-to-peer computing system through each node device for information comparison and to provide accurate identity information. Based on this, this invention can also minimize the possibility of tampering with a system and impersonating an identity.

[0116] Specifically, the peer-to-peer computing system determines the permissions of an object by verifying the authenticity of its identity information. In this system, node devices capable of acquiring identity information may not provide the identity information (or may provide it depending on implementation requirements), but instead express the verification result in their own result data based solely on the verification requirements for the authenticity of the identity information within the received result data. That is, in this invention, even when a node device capable of acquiring identity information does not provide it, the verification result is expressed in its own result data based solely on the verification requirements for the authenticity of the identity information within the received result data.

[0117] When a node device in a peer-to-peer computing system that can obtain identity information does not provide identity information, the information source device that drives the provision of identity information establishes an encrypted file transmission channel with the input terminal of the node device that needs to obtain identity information, or establishes an encrypted information transmission channel using other network communication modes; and uses the identity information as one of the inputs of the node device.

[0118] When necessary, in order to meet the needs of other traditional computing modes for raw data, such as the need for evidence preservation in traditional evidence presentation, in this embodiment, the node settings can be equipped with a data storage device for storing the raw data sensed by the sensor.

[0119] In practical implementation, the node device can also be equipped with leakage protection and other functions in its power supply. The node device can also provide various communication interfaces, including fiber optic interfaces and wireless communication interfaces; it can also provide a data interface for connecting external storage devices. The node device can be powered by solar energy or mains power. When implemented outdoors, the node device can be installed on poles such as streetlights (without crossarms, mounted on the main pole, or integrated into the lampshade); in pole-less areas, if implemented indoors, it can be wall-mounted or integrated into the ceiling.

[0120] When this invention is implemented indoors and outdoors, the node devices, as artificial intelligence facilities installed in public spaces, can serve as digital economy infrastructure for urban clusters, providing 24 / 7 seamless coverage. Through collaborative computing across node devices, vehicle identification at any location within the coverage area can achieve near 100% accuracy, with location identification accuracy related to sensor accuracy.

[0121] In this invention's peer-to-peer computing architecture, all node devices are of the same type and function. Each node device dynamically adjusts its data processing model in real time according to the consensus mechanism of the peer-to-peer computing system. The raw data collected by the data acquisition devices (including sensors, cameras, etc.) connected to each node device is processed and encrypted by the node device according to its own data processing model, generating byte-level processing and encryption results (i.e., result data). This result data is then sent to other node devices (the computation and encryption results output by other node devices simultaneously received by the current node device are also considered part of the raw data collected by the current node device). Therefore, the effect of the raw data sensed by each sensor will propagate exponentially among a massive number of peer-to-peer node devices. If each node device sends its result data to 100 surrounding node devices, after four units of time, hundreds of millions of node devices will be affected by the event sensed by that sensor. In this computing model, information is relatively symmetrical and immune to tampering and forgery. It fundamentally solves the inherent hidden dangers of traditional information technology, namely, the false, forged, and erroneous information caused by information asymmetry, which in turn become entry points for fraud and cyberattacks, as well as the problems of long cycles, poor accuracy, and poor adaptability in complex and integrated applications. In turn, it truly becomes an information infrastructure for comprehensive management of large areas and a digital economy infrastructure.

[0122] This invention utilizes the collaborative computing of a peer-to-peer computing system. When the results of this collaborative computing can identify an event, the event discovery is complete. In this embodiment, the event discovery by the peer-to-peer computing system includes the event's content, its location, and the corresponding response. In a peer-to-peer computing system, all events are processed synchronously; it is not necessarily necessary to explicitly produce staged outputs such as what event was discovered or its specific content. In a peer-to-peer computing system, only the sensor's perception and the corresponding execution device's response are explicitly defined. All other intermediate processes are handled simultaneously by collaborative computing. That is, during the operation of this invention, the intermediate process of event discovery is imperceptible; it is achieved as collaborative computing progresses, the node devices acquire their result data, and the corresponding execution devices automatically respond and execute.

[0123] In this invention, each display and interactive device acts as an execution device, joining the peer-to-peer computing system through one or more node devices. To prevent hijacking, this invention can use multiple node devices to collaboratively control the display and interactive device, further enhancing immunity to hijacking attacks. The human-computer interaction device associated with the participating user connects to the node devices as an access device, and the participating user submits meeting arrangement requests to the peer-to-peer computing system. In this invention, meeting arrangement requests, information interaction service requests, display control commands, and execution control commands can be considered as request commands. Responses to request commands include various scenarios such as "request-execution," "request-response," or others. When the result data calculated by one or more node devices in the peer-to-peer computing system matches the request command, the result corresponding to the request command is represented in the result data output by one or more node devices, according to preset conditions, a pre-deployed program, or a data processing model deployed on the node device. If, based on collaborative computing, it is determined that the current node device needs to respond to the request command, the current node device will send instructions to the execution device connected to it according to the calculated result data, controlling the execution device to complete the response action; this is the "request-execution" scenario. In this invention, if it is determined based on collaborative computing that a display or interactive device needs to display meeting materials, the current node device will send a display control command to the display or interactive device connected to the current node device according to the calculated result data, and control the display or interactive device to complete the display of meeting materials.

[0124] Based on peer-to-peer computing, collaborative computing can be performed by an execution device as a node device. As collaborative computing progresses, when the result data obtained by the execution device corresponds to the request command and can be used to perform related operations, the execution device completes the response to the request command. In this invention, meeting materials are represented by result data; the display and interactive device receive the result data output by the connected node devices. If a specific element in the result data indicates that the display or interactive device needs to display meeting materials;

[0125] Alternatively, the resulting data can be used as one of the inputs to the data processing model of the node device to calculate and determine the corresponding display or interactive device needed to display the meeting materials, and then the display or interactive device can display the corresponding meeting materials.

[0126] When a display or interactive device needs to show meeting materials, it combines the received output data from other node devices to calculate its own result data. Based on this result data, it controls the display or interactive device to display the corresponding meeting materials. In this invention, the display or interactive device does not need to first determine whether it needs to respond. Instead, it combines the received output data from other node devices with the perception data collected by its own sensors, inputs this data into its own data processing model, and outputs the result data indicating whether the display or interactive device should display meeting materials, and what meeting materials should be displayed.

[0127] In this invention, the calculated results include the optimal solution for all scenarios obtained through collaborative computation between all participating users within the display area and the external environment at the current moment; meeting materials are displayed via monitors or interactive devices. In this invention, the results of various information calculations in the peer-to-peer computing system are presented as result data. All monitors and interactive devices, as node devices, contribute the optimal solution for all scenarios during collaborative computation within the peer-to-peer computing system. Furthermore, all display control commands and execution control commands for monitors and interactive devices are the optimal solution commands output by the node devices connected to them after collaborative computation. This invention eliminates the traditional generation and transmission commands to avoid security vulnerabilities in generation and transmission commands that could make monitors and interactive devices risk points.

[0128] In this embodiment, the display and the interactive device are node devices that connect to the execution components of specific functions. The execution feedback information of the execution components of the display and the interactive device is fed back to the display and the interactive device respectively, and participates in the calculation of the subsequent result data of the display and the interactive device.

[0129] In this invention, since the display and interactive device can serve as node devices, their response execution is based on the computational results obtained through collaborative computing, resulting in high response efficiency and avoiding illegal responses such as false execution or failure to execute when required due to network attacks. To prevent hijacking, this invention can also use multiple node devices to collaboratively control the display and interactive device, further enhancing its immunity to hijacking attacks.

[0130] In a peer-to-peer computing system, the result data calculated and output by node devices can be implemented as a state corresponding to the perceived data (i.e., the raw data), which can be represented using state values. Therefore, node devices do not need to store and transmit the raw data. In this embodiment, the data or elements in the multidimensional matrix are related to the installation location, attributes, etc., of each node device. Therefore, when transmitting the result data, what is actually transmitted is the transcoded result after transcoding multiple sets of parameters. A multidimensional matrix is ​​actually a combination of multiple sets of parameters. For example, if the path to a target is from abcd, and the physical locations of the abcd node devices are fixed, then the sequence abcd can be expressed using a single character or a similar concept during multi-parameter transcoding and transmission.

[0131] Based on the technical characteristics of peer-to-peer computing, it can be applied to various application scenarios that provide targeted services or control for a specific target or event. Since the data transmitted between node devices is the result of information processing, rather than the information itself, the raw data collected (i.e., perceived data) does not need to be stored. Node devices only receive the computation results output by other node devices and send out their own computation results. The information contained in a single computation result is insufficient to reconstruct any event or target information; a definite result can only be obtained through collaborative computation involving the computation results across the entire peer-to-peer computing system, multi-dimensional data matrix elements, and the correspondence between physical space and facilities. Collaborative computation has less dependence on the information transmitted by a few node devices, thus fundamentally changing the traditional single-point security sensitivity of information systems.

[0132] In this invention, since the output data of each node device reflects the state evolution of the output data of the preceding node devices, the behavior, attributes, state, or events of the target when it was perceived by the preceding node devices can be inferred based on the output data received by the current node device. For example, when it is necessary to find the location of target 'a' 15 minutes ago, the location of the node device that perceived target 'a' can be obtained at the current moment, thus inferring the location of target 'a'. Then, based on the transmission path of the output data, it can be inferred back to 15 minutes ago to estimate the location of target 'a' 15 minutes ago (determined by the node device that perceived target 'a'). Furthermore, the node device does not need to store the original data about target 'a'. That is, based on this invention, it is not necessary to identify the original data to find target 'a', but rather to first infer the node device that perceived target 'a', and if necessary, obtain the original data about target 'a' at the time when it needs to be found from the storage device connected to the node device.

[0133] In this invention, the display and interactive device receive result data output by other node devices. The principle is as follows: when a corresponding display or interactive device needs to display meeting materials, if the result data calculated by one or more node devices can determine the display or interactive device that needs to display the meeting materials, then the corresponding display or interactive device is added to the node list for transmitting the current result data. The one or more node devices directly transmit the result data to the display or interactive device or the node device connected to the display or interactive device. The corresponding display or interactive device is added to the node list for transmitting result data based on preset conditions or algorithm output or model output.

[0134] Alternatively, displays and interactive devices receive result data from other node devices in a layer-by-layer transmission manner. During collaborative computing in a peer-to-peer computing system, each node device calculates a list of nodes that need to receive the result data. Based on the current result data, it clearly identifies one or more execution devices (including displays and interactive devices) that need to be added, and these are added to the node list. The execution device or the node device connected to it is then used as the next-layer node device to directly receive the current result data, thus bypassing normal layer-by-layer transmission and transforming the peer-to-peer computing system into a three-dimensional architecture. For example, if the result data of the current node device clearly indicates the need for evidence, according to the normal layer-by-layer transmission method, the result data of the current node device would require at least one or more layers of transmission to reach the corresponding node device. However, by adding the corresponding node device to the node list, the corresponding node device can directly receive the result data of the current node device during the next layer of transmission, thereby significantly shortening processing time and improving responsiveness. This invention employs a peer-to-peer computing system; therefore, this temporary construction is precisely the advantage of this invention. Traditional layer-by-layer information aggregation architectures cannot withstand the complex computing demands brought about by such a temporary network construction.

[0135] The above embodiments are merely illustrative of the present invention and are not intended to limit the invention. Any changes or modifications to the above embodiments based on the technical essence of the present invention will fall within the scope of the claims of the present invention.
