Description

Technical Field

[0001] This invention relates to the field of 3D visualization technology, and more specifically to a 3D visualization and intelligent control platform. Background Technology

[0002] Ventilation systems typically consist of fans, ducts, valves, sensors, and control units. They regulate temperature and humidity, disperse harmful gases, and ensure the safety of the operating space by organizing airflow. Their operation often involves dynamic coupling of multiple nodes, loops, and operating conditions. A 3D visualization and intelligent control platform is a digital integrated environment built upon this foundation. Utilizing 3D modeling technology, it interactively presents structural and operational elements such as fan layout, duct routing, branch resistance, and flow field distribution in a unified 3D space. It integrates real-time monitoring data, intelligent analysis models, and adaptive control logic, enabling the platform to dynamically display, predict trends, and strategically adjust airflow, air pressure, air velocity, gas concentration, and equipment health status. This achieves end-to-end intelligent management, from visualizing the spatial structure and sensing the operational status to identifying risks and anomalies and adjusting control strategies. It provides precise scheduling and highly reliable control capabilities for safe ventilation operation in complex scenarios.

[0003] The existing technology has the following shortcomings:

[0004] In existing technologies, dynamic rendering of 3D flow fields typically relies on time-stamped rendering to ensure the continuous evolution of streamlines over time. However, when the rendering pipeline is in a transient switching state, the frame synchronization mechanism is prone to misalignment, causing phase drift in the time series during rendering. This drift causes streamlines to exhibit an antiphase distribution in the 3D model, leading the visual system to misinterpret the originally stable airflow direction as backflow or blockage. Furthermore, since the control logic of existing technologies generally relies on the graphics rendering results to determine flow rate, once such an antiphase distribution occurs, the ventilation system will incorrectly trigger forced ventilation adjustment strategies, misidentifying normal areas as high-resistance zones, ultimately causing a sudden increase in local wind pressure, abrupt changes in wind speed, and abnormal equipment load, potentially leading to overall instability of the ventilation system.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a three-dimensional visualization and intelligent control platform to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The 3D visualization and intelligent control platform includes a time-series buffer construction module, a flow direction matching correction module, an anti-phase shielding and isolation module, an energy uniformity path module, and a rhythmic ventilation mapping module.

[0009] Timing buffer construction module: Constructs a continuous timing buffer band around the time tagging mechanism of the 3D flow field, so that before the rendering pipeline enters the transient switch, it rearranges the time index of the previous frame and the current frame in the continuous timing buffer band to form a continuous sliding interval, providing a stable time base for the smooth transition of the rendering frame series.

[0010] Flow direction matching correction module: Based on the continuous sliding interval formed by the continuous temporal buffer, the flow direction matching window is embedded in the rendering pipeline. The flow direction matching window adjusts the streamline direction in real time using the velocity vector difference between adjacent frames, and introduces the residual phase drift in the continuous sliding interval into the direction channel to establish the direction baseline for subsequent spatial correction.

[0011] Inverse Shielding Isolation Module: Based on the directional channel generated by the flow matching window, a local inverse shielding layer is laid in the 3D model. The local inverse shielding layer actively suppresses inverse rendering according to the vector offset of the directional channel, and isolates the misaligned rendering fragments outside the main flow line, providing a spatial isolation prerequisite for energy uniformity processing.

[0012] Energy unification path module: Around the spatial isolation area formed by the local inversion shield layer, an energy unification path is introduced between the rendering layer and the control logic layer. The energy unification path redistributes the flow velocity gradient on both sides of the local inversion shield layer according to the actual flow direction of the directional channel, so as to achieve the unification of the direction of the visual flow of the rendering layer and the logical flow of the control logic layer.

[0013] Rhythmic ventilation mapping module: Based on the unified direction formed by the energy consistency path, a rhythmic ventilation mapping chain is deployed in the control logic layer. The rhythmic ventilation mapping chain performs delayed distribution according to the rhythm of the actual flow direction, keeping the adjustment command synchronized with the actual flow direction, thereby realizing the dynamic and stable operation of the rendering logic and the control logic.

[0014] Preferably, the step of constructing a continuous temporal buffer band around the time-stamping mechanism of the three-dimensional flow field includes:

[0015] To capture the time information of each frame of rendering data in the 3D flow field before it enters the rendering pipeline, a frame-level time tag capture process is established, and the time tags of all frames to be rendered are pre-scanned and a time index list is generated.

[0016] By recombining the time indices of the previous frame and the current frame, a continuous sliding interval is formed between the previous frame and the current frame in the time dimension, and the time index is rearranged in the continuous time buffer.

[0017] A smooth transition rule for time indexing is established within the formed continuous sliding interval so that each frame in the continuous temporal buffer gradually inherits the time termination value of the previous frame and transitions to the time start of the current frame.

[0018] After stabilizing the sliding interval, the frame series of the rendering pipeline is time-base locked and transitioned to maintain the linear progression of rendering time in the continuous timing buffer and form a continuous time closed loop.

[0019] Preferably, the step of introducing residual phase drift within the continuous sliding interval into the direction channel includes:

[0020] The start and end times of the continuous temporal buffer are used as the time boundaries for the flow to the matching window, and each time scale in the continuous temporal buffer is matched one by one with the corresponding frame column rendering data and weighted.

[0021] Establish a one-to-one correspondence between the previous frame and the current frame in the same streamline position in three-dimensional space, and record the changes in velocity vector direction and magnitude to form a spatial correspondence;

[0022] Based on the directional changes of velocity vectors in adjacent frames, a smooth correction for the streamline direction is implemented for continuous transition within the continuous sliding interval, and the time range of the sliding interval is appropriately extended when a sudden change in direction is detected.

[0023] The corrected flow direction values ​​are recorded sequentially and projected onto the direction channel to form a continuous direction trajectory on the time axis, which is then smoothed over time to serve as the direction baseline for subsequent spatial corrections.

[0024] Preferably, when smoothing the streamline direction within the continuous sliding interval, the flow direction matching window automatically adjusts the transition rate based on the angle change of the velocity vectors in adjacent frames, and dynamically extends the time range of the continuous sliding interval when a sudden change in direction is detected, so that the change in streamline direction remains continuous, thereby avoiding streamline phase reversal and improving the stability of the flow direction baseline in the direction channel.

[0025] Preferably, the step of laying a local inversion shielding layer in the 3D model to isolate the misaligned rendering fragments outside the main line includes:

[0026] Spatial mapping and phase inversion identification are performed on the vector offset information recorded in the direction channel. The vector offset information of the direction channel is projected into the coordinate space of the three-dimensional model, and the potential phase inversion region is determined according to the magnitude of the direction change.

[0027] A local anti-phase shielding layer is generated based on the spatial coordinates of the identified anti-phase region. The boundary range of the potential anti-phase region is determined and an envelope surface is constructed around it to form a spatial isolation profile. The spatial thickness and extension direction of the local anti-phase shielding layer are controlled according to the density of the potential anti-phase region.

[0028] When the rendering pipeline generates a frame, the rendered fragments located within the coverage area of ​​the local inversion shield are actively isolated and stored in the isolation channel, and a smooth transition is performed in the boundary area of ​​the main flow line to restore the integrity of the flow field direction and maintain consistency with the real air flow.

[0029] Preferably, when the envelope of the local antiphase shielding layer is generated, its spatial thickness is adaptively adjusted according to the spatial density of the potential antiphase region, and the extension direction maintains a preset angle with the main direction of the local flow field to ensure a smooth transition between the shielding layer boundary and the normal flow direction region. After the rendering fragments within the coverage area of ​​the local antiphase shielding layer are isolated, the continuity of the main flow direction and visual stability are maintained through the boundary smoothing process of the isolation channel.

[0030] Preferably, the step of introducing an energy consistency path between the rendering layer and the control logic layer includes:

[0031] After the local anti-phase shielding layer is established and a spatial isolation zone is formed, the dominant flow direction on both sides of the local anti-phase shielding layer is determined according to the directional channel, and an energy transition boundary and energy transition zone are constructed around the outer edge.

[0032] Based on the actual flow direction, the velocity gradient in the energy uniformity path is redistributed, prioritizing the balancing of the region with the greatest velocity difference and forming a gradual distribution.

[0033] The energy flow direction is uniformly adjusted according to the direction vector provided by the direction channel, so that the visual flow direction of the rendering layer coincides with the control flow direction of the management logic layer.

[0034] Implement a stable output, continuously monitor changes in flow velocity on both sides and perform continuous balancing and boundary adaptive updates to maintain the energy-consistent pathway extending along the latest direction.

[0035] Preferably, during the stabilization output process, the energy consistency path automatically adjusts the spatial range and energy distribution ratio of the energy transition zone by real-time monitoring the velocity gradient changes on both sides of the local anti-phase shielding layer, and synchronously corrects the extension path of the energy suppression path when the direction channel is updated, so as to ensure the continuity of energy transfer and the directional consistency between the rendering layer and the control logic layer.

[0036] Preferably, the steps for deploying the rhythmic ventilation mapping chain in the control logic layer include:

[0037] After establishing a unified energy pathway and forming a unified directional basis, rhythm monitoring points are set up to record airflow velocity, flow direction changes and local pressure, forming a flow direction rhythm template.

[0038] The regulation command is delayed and mapped based on the flow propagation time of the flow direction rhythm template and the energy unification pathway, so that the execution time corresponds to the actual flow direction rhythm;

[0039] The delayed adjustment instructions are distributed to the control points according to the beat of the flow rhythm template, and the adjacent areas are coordinated according to the directional consistency of the energy homogenization pathway.

[0040] Synchronization correction is implemented based on the time difference between the rendering layer display and the control logic layer feedback, automatically adjusting the delay distribution interval and updating the direction information to keep rendering and control synchronized.

[0041] Preferably, when the rhythmic ventilation mapping chain executes the delayed mapping of the regulation command, it dynamically adjusts the delayed distribution interval according to the flow propagation time interval of the energy uniformity path, and reconstructs the beat interval by combining the real-time update results of the flow rhythm template, so that the effective phase of the regulation command is synchronized with the airflow propagation rhythm, thereby achieving rhythm adaptive distribution and continuous direction correction when the system operating conditions change.

[0042] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0043] This invention introduces a continuous temporal buffer and flow direction matching window during the rendering process, enabling dynamic and continuous connection of the 3D flow field in both time and direction dimensions, eliminating frame misalignment and phase drift issues during transient transitions. Through real-time correction and sliding transition control of streamline direction, the flow field rendering maintains visual smoothness and consistency, avoiding phenomena such as reversed airflow direction and streamline jumps. This ensures the continuity and predictability of the spatial evolution of the ventilation process, significantly improving the stability and realism of 3D visualization in complex ventilation scenarios.

[0044] This invention achieves directional and energy unification between the rendering layer and the control logic layer by constructing an anti-phase shielding layer and an energy unification path, ensuring that the visually presented flow direction is synchronized with the decision-making basis of the control logic. Combined with the delayed distribution mechanism of the rhythmic ventilation mapping chain, it ensures precise temporal alignment between adjustment commands and the actual flow direction, eliminating ventilation instability caused by misjudgment of direction or execution lag. This enables coordinated linkage between the rendering logic and the control logic under complex dynamic conditions, improving the safety, control accuracy, and operational reliability of the ventilation system.

[0050] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art.

[0051] like Figures 1 to 4 As shown, the present invention provides a three-dimensional visualization and intelligent control platform, including a time-series buffer construction module, a flow direction matching correction module, an anti-phase shielding isolation module, an energy uniformity path module, and a rhythmic ventilation mapping module;

[0052] Timing buffer construction module: Constructs a continuous timing buffer band around the time tagging mechanism of the 3D flow field, so that before the rendering pipeline enters the transient switch, it rearranges the time index of the previous frame and the current frame in the continuous timing buffer band to form a continuous sliding interval, providing a stable time base for the smooth transition of the rendering frame series.

[0053] The time indices of the previous frame and the current frame are rearranged within a continuous temporal buffer to form a continuous sliding interval. The specific steps are as follows:

[0054] First, a frame-level time stamp capture process is established to capture the time information of each frame of rendering data in the 3D flow field before it enters the rendering pipeline. Each frame of data is appended with a unique time stamp when it is output from the flow field calculation stage. The time stamp records the actual physical time and generation order of that frame. When the rendering frame sequence is about to enter the rendering pipeline, the time stamps of all frames to be rendered are pre-scanned, and a time index list is generated according to their chronological order. To ensure that the previous frame and the current frame are continuously connected in the time dimension, the time index of the current frame is analyzed by difference with the time index of the previous frame, and a transition interval is inserted between them. The length of the transition interval is automatically determined based on the time interval between the two frames. After this processing, the time stamp of each frame is no longer an isolated point, but forms a continuous time chain with the preceding and following frames, giving the time stamp sequence a clear chronological order and continuous span, thus providing a complete time basis for subsequent time buffering operations.

[0055] After time stamp capture and index generation are completed, a time index reordering process is established. This involves recombining the time indices of the previous and current frames, creating a continuous sliding interval across the time dimension. First, the end of the previous frame's time index is extended and overlapped with the beginning of the current frame's time index on the time axis, providing a certain width for the time transition between the two frames. Then, through the reordering of the continuous sliding interval, the time stamps are re-ordered so that the start of the time buffer corresponds to the end of the previous frame, and the end of the time buffer corresponds to the start of the current frame. This continuous reordering operation prevents direct jumps when switching frame sequences in the rendering pipeline; instead, it smoothly transitions between frames within the continuous time buffer. When transient changes or delays occur during rendering, the sliding interval of the continuous time buffer automatically expands, dynamically adjusting the overlap width to absorb time offsets caused by frame synchronization errors, ensuring that the time sequence during rendering remains linearly progressive.

[0056] After establishing the continuous sliding interval, the resulting continuous temporal buffer is stabilized to ensure that the reference position of the time index remains fixed and predictable throughout the sliding process. To this end, a smooth transition rule for the time index is established within the continuous sliding interval, allowing each frame in the continuous temporal buffer to gradually inherit the time termination value of the previous frame and gradually transition to the time start point of the current frame as it approaches the current frame. Specifically, within the continuous sliding interval, the time index is adjusted step-by-step according to its relative position to the end point of the previous frame. This means that the initial region mainly retains the temporal trend of the previous frame, the middle region achieves a blending and connection of the time labels of the two frames, and the final region gradually transitions to the temporal rhythm of the current frame. Through this continuous transition, the time index within the continuous sliding interval forms an inherently coherent temporal distribution, ensuring that the time value at any given moment remains consistent with the actual physical temporal sequence. This stabilization process ensures that the rendering pipeline does not experience time jumps or regressions during frame transitions, maintaining a consistent temporal progression throughout the entire flow.

[0057] After stabilization is completed within the continuous sliding interval of the continuous timing buffer, the frame series of the rendering pipeline undergoes time base locking and transition output to ensure that the temporal continuity of the continuous timing buffer is carried over to the rendering output stage. Specifically, in the output stage, the stabilized continuous sliding interval serves as the time-driven basis for rendering, ensuring that the rendering start point of the new frame strictly corresponds to the time end point of the previous frame, thus forming a strict temporal closed loop in the output order of the frame series. As the rendering process progresses, the rendering calculation of each frame uses the output time of the previous frame as the starting reference, and the new rendering result naturally connects with the previous frame in time. When the rendering process encounters transient situations such as system switching, data delays, or time drift, the continuous timing buffer actively corrects the output order of the frame series through automatic sliding of the time index and time rearrangement, ensuring that the linear progression of rendering time is not disrupted. Through this locking and transition mechanism, the rendered frame series presents a coherent and stable sense of time flow in visual representation, allowing the streamlines to evolve continuously in three-dimensional space. This not only eliminates the directional jumps caused by phase drift, but also provides a strict time reference basis for subsequent flow direction matching, energy uniformity, and rhythmic ventilation control.

[0058] Through the above steps, the continuous temporal buffer not only achieves hierarchical capture and orderly rearrangement of time tags during the rendering of the 3D flow field, but also establishes a smooth transition and baseline locking of the time index within the continuous sliding interval. This gives the rendering frame series adjustable, absorbable, and extensible buffering characteristics in the time dimension. This time management method can achieve continuous flow of time sequence without increasing computational latency, avoiding time misalignment during transient switching of the rendering pipeline, and ensuring that the rendering results of the 3D flow field maintain a visually stable and natural time progression effect.

[0059] Flow direction matching correction module: Based on the continuous sliding interval formed by the continuous temporal buffer, the flow direction matching window is embedded in the rendering pipeline. The flow direction matching window adjusts the streamline direction in real time using the velocity vector difference between adjacent frames, and introduces the residual phase drift in the continuous sliding interval into the direction channel to establish the direction baseline for subsequent spatial correction.

[0060] The residual phase drift within the continuous sliding interval is introduced into the direction channel. The specific steps are as follows:

[0061] After a stable sliding interval is formed in the continuous temporal buffer, a time mapping range for the flow direction matching window is established. To ensure a complete temporal correspondence between the flow direction matching window and the continuous sliding interval, the start and end times of the continuous temporal buffer are first used as the time boundaries of the flow direction matching window, ensuring that the time span of the flow direction matching window completely overlaps with the continuous sliding interval. Next, each time scale point within the continuous temporal buffer is mapped one-to-one with the rendering data of the corresponding frame series, ensuring that the velocity vector information of each frame can be independently read and recorded within the flow direction matching window. Through this time mapping method, the flow direction matching window obtains continuous temporal input, enabling it to track the streamline direction at any moment within the continuous temporal buffer in real time. Simultaneously, the time sequence within the continuous sliding interval is weighted during this process, resulting in a smooth progression of time periods within the window, ensuring the continuity and traceability of the flow direction matching on the time axis, thus providing a precise temporal basis for subsequent direction adjustments.

[0062] After establishing the temporal mapping range, a spatial correspondence is established for the streamline direction information within the continuous sliding interval. Specifically, in each frame of the continuous temporal buffer, the streamline direction is represented by the velocity vector at that moment, and the task of the streamline matching window is to find the directional relationship of corresponding spatial points between adjacent frames. To this end, the positions of the same streamline in the previous frame and the current frame in three-dimensional space are matched, and the changes in the direction and magnitude of the velocity vector at the same position in the two frames are recorded. During the spatial mapping process, the spatial coordinates of the previous frame and the current frame are kept in a one-to-one relationship within the streamline matching window, so that the directional change of each streamline can be accurately tracked. When a slight inter-frame offset occurs in the continuous sliding interval, the streamline matching window can automatically expand the corresponding range according to the temporal mapping order to ensure that the spatial matching relationship is not interrupted. Through this spatial correspondence method, the streamline matching window has continuous tracking capability on both the time axis and the spatial axis, thereby accurately capturing the directional differences between adjacent frames and providing a reliable spatial basis for subsequent directional adjustments.

[0063] After completing the temporal mapping and spatial correspondence, the flow direction matching window enters the direction adjustment stage. The key to this stage is to smoothly correct the streamline direction within the continuous sliding interval by utilizing the relationship between the velocity vector direction changes of the previous and current frames, thus offsetting residual direction errors caused by phase drift. To this end, the flow direction matching window compares the streamline direction at each moment within the continuous sliding interval with the streamline direction at the previous moment, and gradually adjusts the streamline direction at the current moment based on the angle between the two and the trend of direction offset. The adjustment process is not an instantaneous jump, but a continuous transition within the time span of the continuous sliding interval, maintaining a natural visual extension of the streamline direction. Simultaneously, when a sudden change in direction is detected during frame switching, the flow direction matching window automatically extends the time range of the continuous sliding interval, smoothly distributing the direction change over a longer time period, thereby avoiding the streamline inversion phenomenon caused by sudden direction changes. Through this frame-by-frame continuous adjustment method, the streamlines remain consistent with the airflow direction throughout the entire continuous sliding interval, achieving temporal and spatial directional unity, allowing the 3D flow field to exhibit stable flow continuity in visual rendering.

[0064] After the streamline direction is adjusted through the flow direction matching window, the adjusted direction data is incorporated into the direction channel to construct a direction baseline for subsequent spatial correction. During this process, each time point within the continuous sliding interval corresponds to a corrected flow direction value, which is sequentially recorded and projected onto the direction channel, forming a continuous direction trajectory on the time axis. The generation of the direction channel not only records the temporal evolution of the streamline direction but also retains residual phase drift information within the continuous sliding interval, making it the basis for spatial correction in the subsequent anti-phase shielding and energy unification stages. To ensure the stability of the direction channel, the direction data within the channel is temporally smoothed during this process, ensuring a continuous transition in direction changes between adjacent time points. When the rendering pipeline calls the direction channel information in subsequent stages, it can quickly identify the true direction and spatial distribution of the streamlines based on the direction baseline, thereby avoiding visual reversals caused by local temporal errors. By establishing this directional channel, the time, space, and direction information within the continuous sliding interval are integrated, enabling the entire three-dimensional flow field to form a continuous and physically consistent baseline structure in the direction dimension, providing a high-precision directional basis for subsequent anti-phase shielding and energy correction.

[0065] Through the above steps, the flow direction matching window achieves a two-dimensional fusion of time and space based on the continuous temporal buffer. It not only ensures continuous connection of direction changes on the time axis but also guarantees the consistency of streamline direction on the spatial axis. This implementation can correct flow direction offsets and absorb residual phase drift in real time during dynamic switching of the rendering pipeline, keeping the streamline direction synchronized with the physical flow state, thus eliminating flow direction reversal and direction jump problems at the visual level. By uniformly introducing direction changes within the continuous sliding interval into the direction channel, a stable direction baseline is further formed, allowing subsequent spatial correction and control strategies to be executed based on the actual flow direction. The entire process not only ensures the directional continuity and visual stability of the 3D flow field in dynamic rendering but also provides dynamic support for the intelligent management of the ventilation system with consistent direction and unified logic.

[0066] Inverse Shielding Isolation Module: Based on the directional channel generated by the flow matching window, a local inverse shielding layer is laid in the 3D model. The local inverse shielding layer actively suppresses inverse rendering according to the vector offset of the directional channel, and isolates the misaligned rendering fragments outside the main flow line, providing a spatial isolation prerequisite for energy uniformity processing.

[0067] A local inversion masking layer is applied to the 3D model to isolate the misaligned rendering fragments from the main line. The specific steps are as follows:

[0068] After the directional channel is formed, the vector offset information recorded in the directional channel is spatially mapped and phase-reversed. The directional channel contains time-series information of the streamline direction of each frame within a continuous sliding interval, and also records the directional change trend and spatial distribution path between adjacent frames. To accurately identify potential phase-reversing regions in the streamline direction, the vector offset information of the directional channel is projected into the coordinate space of the 3D model, and the position of each streamline node is mapped one-to-one with its direction vector. In this process, the vector offset data in the directional channel is distributed to each flow unit in the 3D space, giving each unit its own directional attribute. When the directional change amplitude of a certain spatial region exceeds the set range of the average directional change amplitude of the preceding and following frames, it is determined that the region has a potential phase-reversing trend and is marked as a potential phase-reversing region. Through this identification process, it can be clearly identified which local spatial nodes in the flow field have experienced reverse directional shifts, thus providing accurate spatial positioning basis for the subsequent generation of the phase-reversing shielding layer. Since the generation process of the directional channel has eliminated the interference of time drift, the phase-reversing identification here can truly reflect the regions with inconsistent flow directions in space, ensuring the accuracy of the phase-reversing determination.

[0069] After identifying the directional offset regions, a local anti-phase shielding layer is generated in the 3D model based on the spatial coordinates of potential anti-phase regions within the directional channels. The formation of this local anti-phase shielding layer is a process closely integrated with spatial geometry and flow direction distribution. Specifically, the boundary range of the potential anti-phase regions is first determined, and all nodes within this range that are offset in the opposite direction to the mainstream flow direction are spatially aggregated to form a preliminary set of anti-phase regions. Subsequently, an envelope surface is constructed around these sets; this envelope surface is the spatial outline of the local anti-phase shielding layer. To ensure the shielding layer is structurally consistent with the 3D model, its spatial thickness, coverage area, and extension direction are precisely controlled. The spatial thickness of the local anti-phase shielding layer is determined based on the spatial density of the potential anti-phase regions and the streamline distribution density, ensuring that it completely covers the potential anti-phase regions without interfering with the rendering of adjacent normal streamlines. When the 3D model has complex branching or intersecting structures, the extension direction of the local anti-phase shielding layer needs to maintain a certain angle with the main direction of the local flow field to ensure a natural transition between the shielding layer's boundary and the normal flow direction region, avoiding visual discontinuities. Through this spatial envelope method, the local antiphase shielding layer forms a semi-transparent spatial isolation layer in the 3D model, which can effectively block or weaken the antiphase streamlines, so that they are naturally excluded from the distribution range of the mainstream lines in visual rendering.

[0070] After the local inversion shield is established, misaligned rendering fragments are actively isolated, forming an independent spatial isolation zone outside the main flow line to ensure that the energy flow direction and rendering direction remain spatially consistent. Specifically, when the rendering pipeline generates a 3D image, if it detects a rendering fragment within the coverage area of ​​the local inversion shield, that fragment will no longer participate in the normal rendering output as part of the main flow line. Instead, it will be marked as an inverted fragment and stored separately in the isolation channel of the local inversion shield. The isolation channel spatially separates the inverted region from the normal flow region, ensuring that the rendering process of the main flow line is not affected by abnormal fragments. The isolated inverted fragment still retains its spatial position coordinates and velocity information, but it is downgraded in the rendering result, appearing as low brightness or blurry, thus completely separating it from the main flow direction visually. At the same time, the boundary area of ​​the local inversion shield and the intersection with the main flow direction are automatically smoothed, allowing the direction of the main flow line to naturally transition to the normal area, avoiding boundary discontinuities caused by the isolation operation. Through such spatial isolation, the reverse rendering fragments caused by frame misalignment or directional drift are effectively removed, the directional integrity of the main lines is restored, and the visual presentation of the flow field returns to a state consistent with real air flow.

[0071] It should be noted that the mainstream flow line refers to the set of main airflow paths in the 3D flow field, determined after correction based on continuous temporal buffer zones and directional channels, and consistent with the actual airflow direction. The mainstream flow line represents the dominant airflow transmission direction and energy transfer channel of the ventilation system under current operating conditions. Its flow direction remains continuous and stable in time and space, serving as the benchmark flow direction used by the rendering layer for flow field visualization and by the control logic layer for airflow and pressure adjustment. Compared to localized reverse or abnormal streamlines caused by frame misalignment or phase drift, the mainstream flow line reflects the true, effective, and controllable airflow motion state of the system.

[0072] Through the sequential execution of the above steps, the local anti-phase shielding layer achieves a complete process in the 3D model, from identifying anti-phase regions to generating spatial envelopes and isolating rendered fragments, ensuring that the 3D flow field of the ventilation system remains consistent both visually and physically. Relying on the vector offset information provided by the directional channel, the local anti-phase shielding layer can identify and actively suppress local anti-phase phenomena in real time, thereby avoiding visual misleading phenomena such as incorrect streamline direction or reversed airflow paths during rendering.

[0073] By spatially enclosing and isolating potential antiphase regions, the energy distribution in these regions does not interfere with the velocity gradient changes in the mainstream region, providing a clean spatial boundary for the subsequent establishment of energy-uniform pathways. Ultimately, the rendering result of the three-dimensional flow field visually presents a dynamic scene with stable flow direction, clear hierarchy, and continuous structure. This ensures both the visual accuracy of ventilation system operation monitoring and a reliable spatial data foundation for intelligent control strategies.

[0074] Energy unification path module: Around the spatial isolation area formed by the local inversion shield layer, an energy unification path is introduced between the rendering layer and the control logic layer. The energy unification path redistributes the flow velocity gradient on both sides of the local inversion shield layer according to the actual flow direction of the directional channel, so as to achieve the unification of the direction of the visual flow of the rendering layer and the logical flow of the control logic layer.

[0075] An energy consistency path is introduced between the rendering layer and the control logic layer. The specific steps are as follows:

[0076] After the local anti-phase shielding layer is established and forms a spatial isolation zone, an energy transition boundary is constructed to connect the flow regions on both sides of the local anti-phase shielding layer, ensuring the continuity of energy transfer inside and outside the spatial isolation zone. At this stage, based on the actual flow direction information recorded in the directional channel, the dominant flow direction in the regions on both sides of the local anti-phase shielding layer is determined, and an energy transition zone is established at the intersection of the two flow directions. The spatial range of the energy transition zone is centered on the outer edge of the local anti-phase shielding layer. By setting buffer widths on both sides of the outer edge, a smooth energy connection region is formed between the local anti-phase shielding layer and the surrounding flow field. The formation of this energy transition zone allows the energy flow that was originally blocked by the shielding layer to regain a spatial pathway, while avoiding the energy abrupt changes caused by directly crossing the local anti-phase shielding layer. In this way, the energy transition boundary becomes the starting point of the energy unification path, providing a continuous and transferable basis for energy between the visual layer and the logical layer, and providing a connecting bridge for subsequent flow velocity gradient adjustments.

[0077] After the energy transition boundary is constructed, the velocity gradient in the energy unification path is redistributed based on the actual flow direction data on both sides of the local antiphase shielding layer in the directional channel. The core of this process lies in balancing the energy density on both sides according to the vector difference in the flow directions, ensuring a smooth spatial transition of velocity changes on both sides of the local antiphase shielding layer. In this process, the region with the largest velocity difference on both sides of the local antiphase shielding layer is first identified and designated as the priority adjustment range for gradient balancing. Then, based on the actual flow direction relationship provided by the directional channel, the energy flow is gradually guided from the high-energy side to the low-energy side, creating a gradual spatial distribution of the velocity gradient. To ensure a smooth transition, the streamline density within the transition region is adjusted so that the energy transfer direction extends continuously in space without reversal or superposition. Through this redistribution process, the originally discontinuous energy flows on both sides of the local antiphase shielding layer are smoothly connected, forming an energy flow field with a consistent direction, thus establishing a common spatial baseline for energy transfer at both the visual and logical levels.

[0078] After the velocity gradient is redistributed, the energy flow direction is uniformly adjusted to ensure strict consistency between the visual flow direction of the rendering layer and the control flow direction of the management logic layer. The key to this stage is to reorient the flow direction presentation of the rendering layer based on the actual flow direction data from the direction channel, ensuring that the extension direction of the streamlines in the visual display completely overlaps spatially with the airflow direction within the management logic layer. Specifically, in the energy unification path, each energy node corresponds to a direction vector provided by the direction channel. By using these direction vectors as directional guides for energy transfer, the rendering layer automatically displays streamlines along the actual flow direction in the visualization output. Simultaneously, in the management logic layer, the same directional guide serves as the directional benchmark for airflow judgment, ensuring that the management logic's understanding of the airflow direction is consistent with the direction in the visual rendering. Thus, when the ventilation control logic performs airflow adjustment or pressure balancing, the direction of its decision-making is completely synchronized with the direction of the visual presentation, avoiding misjudgments by the control logic due to a reversal of the visual direction. Through this unified adjustment, the energy consistency path combines the flow direction display of the rendering layer and the flow direction control of the management logic layer into the same directional reference system, so that the entire three-dimensional flow field achieves directional synchronization and energy consistency between the visual and logical levels.

[0079] After the energy uniformity path completes energy transition and direction unification, it undergoes stabilization output to ensure long-term consistency of energy transfer between the rendering layer and the control logic layer during the dynamic changes of the ventilation system. The stabilization output process mainly includes two parts: continuous balancing of the energy channel and adaptive boundary updates. First, by continuously monitoring the flow velocity changes on both sides of the local anti-phase shielding layer, when a new flow direction shift is detected, the energy uniformity path automatically adjusts the energy distribution ratio to restore the energy density of the transition area to a balanced state. Second, when the spatial shape of the local anti-phase shielding layer deforms due to changes in system operation, the energy uniformity path automatically updates its spatial path, ensuring that the path always extends along the latest direction channel, thereby guaranteeing that the energy transfer path is not interrupted. Through this adaptive stabilization output mechanism, the energy uniformity path can continuously maintain the energy coupling relationship between the rendering layer and the control logic layer during operation, ensuring consistency between the visual display of the flow field and the control judgment in time, space, and direction.

[0080] Through the above steps, the energy uniformity pathway not only establishes a stable energy transfer connection on both sides of the local anti-phase shielding layer, but also achieves complete unification of visual and logical flow directions. This effectively eliminates the discontinuous energy distribution problem caused by the spatial isolation zone formed by the local anti-phase shielding layer, enabling seamless connection between the visual representation of the 3D flow field in the rendering layer and the decision-making of the control logic layer. By introducing the energy uniformity pathway, the 3D visualization and intelligent control process of the ventilation system achieves overall consistency and directional synchronization of energy flow, ensuring both the physical realism of the rendering effect and the accuracy of the control strategy execution.

[0081] Rhythmic ventilation mapping module: Based on the unified direction formed by the energy uniformity path, a rhythmic ventilation mapping chain is deployed in the control logic layer. The rhythmic ventilation mapping chain performs delayed distribution according to the rhythm of the actual flow direction, keeping the adjustment command synchronized with the actual flow direction, thereby realizing the dynamic and stable operation of the rendering logic and the control logic.

[0082] A rhythmic ventilation mapping chain is deployed in the control logic layer, enabling the rhythmic ventilation mapping chain to perform delayed distribution based on the actual flow rhythm. The specific steps are as follows:

[0083] After establishing an energy unification pathway and forming a unified directional basis, the actual flow rhythm within the ventilation system is captured and identified. The actual flow rhythm refers to the velocity fluctuations and streamline pulsations exhibited by airflow over time in three-dimensional space. To accurately obtain this rhythmic characteristic, rhythm monitoring points are established in key areas at both ends of the energy unification pathway. Each monitoring point continuously records airflow velocity, flow direction changes, and local pressure fluctuations in the flow field. These continuous records form time-series data of the flow field rhythm. Based on this, the flow direction information provided in the directional channel is spatially correlated with the data from the rhythm monitoring points, establishing a correspondence between flow direction changes and velocity fluctuations in the time dimension. In this way, the rhythmic ventilation mapping chain can accurately grasp the periodic characteristics of airflow in space and time when establishing its initial state, forming a flow rhythm template for the ventilation system. This template provides a rhythmic reference for subsequent delayed distribution, enabling the control logic to follow the dynamic rhythm of the actual airflow when executing adjustment actions.

[0084] After obtaining the actual flow rhythm template, the adjustment commands are time-delayed, ensuring that the execution time of each command corresponds to the change in the flow rhythm. The core purpose of this time-delay mapping is to establish a rhythm-synchronized delay mechanism between command issuance and airflow response, matching the control action with the actual propagation speed of the airflow dynamics. In this process, the flow propagation time interval in the energy uniformity path is first determined, i.e., the time interval required for airflow to propagate from one control point to an adjacent area. Subsequently, the execution time of the adjustment command is mapped to this propagation time interval, ensuring that the actual effective time of the command falls on the appropriate phase of the airflow rhythm change. Through this time-delay mapping, the control logic layer does not immediately act on the physical ventilation unit when issuing control commands, but rather distributes them delayed according to the timing rhythm in the flow rhythm template, keeping each command synchronized with the actual airflow direction. This precise temporal correspondence allows the airflow evolution process of the control layer and the rendering layer to completely overlap, preventing distortion in the visual display where control has intervened prematurely without any change in airflow.

[0085] After the adjustment commands complete their delayed mapping, the rhythm distribution phase begins. The delayed commands are distributed to various control points according to the rhythmic beat sequence to ensure the overall rhythmic coordination of the ventilation system. Specifically, in the control logic layer, the flow rhythm template is divided into several consecutive beat intervals, each corresponding to one or a group of adjustment actions. When the airflow rhythm is in the rising phase, the adjustment commands are sequentially applied to the actuators such as fans and valves, gradually increasing the airflow speed. When the airflow rhythm is in the falling phase, the commands are applied in the reverse order, causing the airflow to slowly stabilize. The entire distribution process relies on the directional consistency of the energy uniformity path, ensuring that the direction of each control action is consistent with the actual flow direction. Simultaneously, the spatial correlation between flow directions needs to be considered during the distribution process. When the action of a control point may affect the airflow in adjacent areas, the rhythmic ventilation mapping chain automatically adjusts the action time of that control point according to the flow rhythm template, ensuring its coordination with the action rhythm of surrounding control points. By using this method of spatial and temporal synchronous distribution, all areas of the ventilation system can operate at a unified rhythm, and the changes in airflow speed and direction are consistent with the dynamic flow of the rendering layer, thereby achieving rhythmic operation of the overall ventilation process.

[0086] After the adjustment commands complete the rhythm distribution, the operating states of the rendering layer and the control logic layer are synchronously corrected to ensure that the rhythmic ventilation mapping chain remains stable and consistent during long-term operation. At this stage, the time difference between the flow field changes displayed in the rendering layer and the airflow feedback in the control logic layer is compared. When a rhythm offset or synchronization delay is detected, the rhythmic ventilation mapping chain automatically adjusts the delay distribution interval to realign the control commands with the airflow rhythm. Simultaneously, the directional information in the energy uniformity path is updated to the rhythmic ventilation mapping chain in real time, ensuring that the rhythm correction is synchronized not only in time but also in direction. When the operating conditions of the ventilation system change, such as adjustments to the duct structure or changes in load, the rhythmic ventilation mapping chain can automatically re-identify the new rhythm cycle and update it in the delay distribution logic, thereby ensuring that the rendering layer and the control logic layer remain synchronized under different operating conditions. This correction mechanism enables the rhythmic ventilation mapping chain to be adaptive, continuously tracking system rhythm changes and dynamically adjusting the control response, achieving long-term stable unity between rendering and control logic.

[0087] Through the above steps, the rhythmic ventilation mapping chain, based on the unified directional basis provided by the energy consistency path, completes the entire process from flow rhythm identification and command delay mapping to rhythm distribution and synchronization correction. This enables the ventilation system to achieve strict rhythm matching and time alignment between the visual and logical levels. It not only synchronizes the execution of adjustment commands with the actual airflow propagation process but also achieves dynamic unification of rendering logic and control logic in both direction and rhythm dimensions, thereby ensuring the stability and accuracy of the ventilation system under complex operating conditions. By introducing the rhythmic ventilation mapping chain, there is no longer a time and direction deviation between the three-dimensional visualized streamline changes and the actual control actions, enabling the system to operate in a rhythmic and predictable manner, ensuring that the energy output, flow direction adjustment, and status display of the ventilation process remain coordinated and consistent throughout the entire cycle.

[0088] This invention introduces a continuous temporal buffer and flow direction matching window during the rendering process, enabling dynamic and continuous connection of the 3D flow field in both time and direction dimensions, eliminating frame misalignment and phase drift issues during transient transitions. Through real-time correction and sliding transition control of streamline direction, the flow field rendering maintains visual smoothness and consistency, avoiding phenomena such as reversed airflow direction and streamline jumps. This ensures the continuity and predictability of the spatial evolution of the ventilation process, significantly improving the stability and realism of 3D visualization in complex ventilation scenarios.

[0089] This invention achieves directional and energy unification between the rendering layer and the control logic layer by constructing an anti-phase shielding layer and an energy unification path, ensuring that the visually presented flow direction is synchronized with the decision-making basis of the control logic. Combined with the delayed distribution mechanism of the rhythmic ventilation mapping chain, it ensures precise temporal alignment between adjustment commands and the actual flow direction, eliminating ventilation instability caused by misjudgment of direction or execution lag. This enables coordinated linkage between the rendering logic and the control logic under complex dynamic conditions, improving the safety, control accuracy, and operational reliability of the ventilation system.
