Description

Technical Field

[0001] This invention relates to the field of intelligent management and control products for LED advertising screens, specifically a remote deployment management system for outdoor foldable LED cube advertising screens. Background Technology

[0002] Foldable LED cube advertising screens are widely used in outdoor commercial district advertising, exhibitions, cultural tourism night scene displays, and outdoor marketing promotions due to their advantages of being foldable, easy to store, versatile in form, and offering a novel and three-dimensional display effect. Compared to traditional fixed flat LED advertising screens, cube foldable screens can switch between different display forms by opening, closing, folding, and deforming at multiple angles, resulting in a stronger three-dimensional display effect and better adaptability to various scenarios.

[0003] Currently, the existing control technology for foldable LED cube advertising screens has two major flaws, which seriously restrict the product display effect and intelligence level: First, the existing equipment only supports overall image output in a fixed form and has not established a dedicated image rendering mechanism for the multi-faceted folding deformation characteristics of the cube. When the cube is in a non-standard unfolded state such as folded, half-open, or multi-angle deflection, the spatial position and angle of each folded panel will shift. The uniformly placed advertising materials cannot adapt to the panel deformation state, which is very easy to cause problems such as image misalignment, pixel shift, image tearing, and edge distortion. It is impossible to guarantee the consistency and clarity of multi-faceted display, which seriously affects the quality of advertising display. Second, the current playback mode switching completely relies on manual on-site debugging by staff. It is necessary to manually switch between single-screen, multi-screen, and panoramic playback modes according to the folding posture of the cube. The debugging process is cumbersome, labor costs are high, and response efficiency is low. Moreover, it cannot achieve remote real-time control and adaptive adjustment, making it difficult to adapt to outdoor multi-point, dynamic, and unattended advertising scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a remote projection management system for outdoor foldable LED cube advertising screens to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote deployment management system for an outdoor foldable LED cube advertising screen, comprising a remote cloud management platform, an attitude sensing feedback module, a faceted rendering mapping processing module, a multi-panel independent playback driving module, and a foldable LED cube advertising screen body; the foldable LED cube advertising screen body is a multi-faceted foldable and deformable cube structure, composed of several independently openable and rotatable LED foldable panels spliced ​​together, each foldable panel can independently display images and supports multi-angle folding deformation;

[0006] The attitude sensing feedback module is integrated inside each LED folding panel. It is used to collect the folding angle, opening and closing deformation amplitude, and spatial relative position attitude parameters of the Rubik's Cube as a whole and each individual panel in real time, and transmit the real-time attitude data back to the remote cloud management platform through a wireless communication link.

[0007] The remote cloud management platform has a built-in posture recognition and mode scheduling unit, which is used to receive deformation posture data transmitted from the sensor, identify the current unfolded / folded state of the Rubik's Cube, and automatically match and switch between three preset playback modes: single-screen playback, multi-face linkage playback, and panoramic playback of the 3D Rubik's Cube; at the same time, it receives advertising materials uploaded remotely by users and completes material preprocessing, resolution adaptation, storage and distribution.

[0008] The faceted rendering mapping processing module is coupled to the remote cloud management platform. It has a built-in faceted rendering mapping model based on the multi-faceted folding deformation parameters of the Rubik's Cube. It is used to perform cloud-adaptive splitting, pixel coordinate reconstruction, and image distortion correction on the complete advertising material according to the real-time collected Rubik's Cube folding deformation parameters, and generate sub-screen materials that are adapted to the independent display of each folded panel.

[0009] The multi-panel independent playback driver module is used to receive independent sub-screen materials of each panel distributed from the cloud, and drive the corresponding LED folding panels to output and display independently, so as to achieve accurate matching of multi-faceted screens and display without misalignment or distortion under all working conditions of folding and opening.

[0010] As a preferred embodiment of the present invention, the method for constructing the faceted rendering mapping model includes: collecting spatial coordinate parameters of the Rubik's Cube under different folding angles, opening and closing states, and panel deflection postures, and establishing a three-dimensional spatial pixel mapping matrix for each folded panel; based on the three-dimensional spatial pixel mapping matrix, constructing a one-to-one correspondence mapping relationship between the complete advertising material and the display area of ​​each independent folded panel, and presetting material splitting rules, pixel compensation parameters, and distortion correction algorithms under different deformation conditions.

[0011] As a preferred embodiment of the present invention, the specific workflow of the faceted rendering mapping processing module includes: obtaining real-time folding deformation parameters of the Rubik's Cube from the cloud and importing them into the faceted rendering mapping model; the model automatically retrieves the corresponding material splitting strategy according to the current deformation posture and adaptively splits the original complete advertising material into blocks; performs pixel-level image correction on the spatial deflection angle and deformation displacement of each folded panel to eliminate image stretching, misalignment, and edge distortion caused by folding deformation; and accurately distributes the corrected independent sub-image materials to the corresponding LED folded panels.

[0012] As a preferred embodiment of the present invention, the attitude sensing feedback module includes a high-precision angle sensor, a displacement sensing unit, a wireless transmission unit, and a data filtering unit; the high-precision angle sensor is used to collect the real-time folding and opening angle of each folding panel, with a detection accuracy of 0.1°; the displacement sensing unit is used to collect the panel deformation displacement and relative position parameters; the data filtering unit is used to perform noise reduction filtering on the collected raw attitude data to remove abnormal data caused by outdoor vibration and environmental interference; the wireless transmission unit adopts 5G / 4G dual-mode communication to realize low-latency real-time feedback of attitude data and remote download of cloud materials.

[0013] As a preferred embodiment of the present invention, the mode scheduling logic of the remote cloud management platform includes: when the Rubik's Cube is detected to be fully folded and a single panel is unfolded, it automatically switches to single-screen playback mode, driving only the unfolded panel to independently play the complete advertisement screen; when the Rubik's Cube is detected to be half-folded and multiple panels are simultaneously unfolded, it automatically switches to multi-faceted linkage playback mode, achieving seamless linkage display of multiple panel screens through a faceted rendering mapping model; when the Rubik's Cube is detected to be fully unfolded and a three-dimensional Rubik's Cube is formed, it automatically switches to three-dimensional Rubik's Cube panoramic playback mode, splitting and rendering panoramic materials to achieve multi-faceted combined three-dimensional panoramic advertisement display.

[0014] As a preferred embodiment of the present invention, the system supports remote manual intervention and control. Users can manually lock the playback mode, customize the material splitting rules, and adjust the picture correction parameters through the cloud management backend to adapt to special scene display needs.

[0015] As a preferred embodiment of the present invention, each of the LED folding panels adopts an outdoor high-brightness waterproof LED screen body, which has dustproof, waterproof and anti-interference performance, and is suitable for complex working conditions such as high and low temperatures, wind and rain.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By using a faceted rendering mapping model, we achieve deformation-adaptive material splitting and pixel correction, adapting to all working conditions such as fully folded, half-unfolded, and fully unfolded Rubik's Cubes. This completely solves the problems of image misalignment, distortion, and tearing caused by folding deformation, ensuring the consistency, high definition, and three-dimensionality of multi-faceted advertising display effects.

[0018] 2. Relying on sensor feedback links and cloud-based intelligent scheduling, it achieves fully automatic recognition and switching of playback modes without the need for on-site manual debugging. It supports remote material delivery, parameter adjustment, and status monitoring, and is suitable for outdoor unattended, multi-location, and dynamic advertising operation scenarios, improving operation and maintenance efficiency by more than 80%.

[0019] 3. Three playback modes flexibly adapt to different advertising needs, such as single-point display, multi-faceted promotion, and three-dimensional panoramic display. The combination of the cube's versatile shape and intelligent control mechanism significantly enhances the innovation and visual impact of outdoor advertising displays, making it suitable for various outdoor scenarios such as business districts, exhibitions, cultural tourism, and sports events.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Please see Figure 1-4 This invention provides an embodiment of a remote deployment management system for an outdoor foldable LED cube advertising screen, comprising five parts: a remote cloud management platform, a posture sensing feedback module, a faceted rendering and mapping processing module, a multi-panel independent playback driver module, and the outdoor foldable LED cube advertising screen hardware itself. At the hardware level, the foldable LED cube advertising screen features six independently foldable and rotatable outdoor high-brightness waterproof LED panels. These panels are connected by silent folding hinges, enabling multi-angle folding deformations of 90°, 180°, 270°, and 360° to meet different display requirements. Each panel is internally encapsulated with high-precision angle sensors and miniature displacement sensors, forming a posture sensing feedback module. This module collects real-time data on the folding angle, spatial displacement, and relative position of each panel. After noise reduction processing by a built-in data filtering chip, the data is uploaded to the cloud platform in real-time via a 5G wireless communication module, with a data transmission latency of ≤20ms.

[0028] The cloud platform, as the core control terminal, is equipped with a data receiving and parsing unit, a posture recognition unit, a mode scheduling unit, a material processing unit, and a faceted rendering mapping model. It can receive device posture data in real time and remotely receive user-uploaded images and video advertising materials, completing material format adaptation and resolution optimization. The cloud accurately determines the current form of the device through posture data, automatically matches the corresponding playback mode, and completes adaptive splitting and correction of materials through the faceted rendering model. Finally, it sends the exclusive sub-screen materials of each panel to the terminal driver module to achieve independent display output.

[0029] Beforehand, deformation parameters of the Rubik's Cube under all folding conditions were collected through equipment calibration experiments, including the folding angle, deflection direction, displacement distance, and panel spacing of each panel, to establish a three-dimensional spatial coordinate mapping database. Based on the database, a faceted rendering mapping model was constructed, with preset material splitting algorithms, pixel compensation formulas, and distortion correction parameters corresponding to different deformation parameters.

[0030] In actual operation, the cloud obtains the cube's deformation parameters in real time and imports them into the model. The model automatically matches the rendering strategy corresponding to the current deformation condition: when the cube is in an asymmetrical folded state, for the differentiated deformation parameters of each panel, the display area and pixel matching coordinates of each panel are independently calculated. The original complete advertising video / image material is non-uniformly adaptively split, pixel compensation is performed on the image stretching area caused by deformation, and distortion correction is performed on the edge offset area. Finally, 6 sets of independent distortion-free sub-image data are generated and sent to the corresponding LED panels to ensure that the multi-faceted images are connected naturally and without misalignment or distortion in any folded state.

[0031] The attitude sensing feedback module collects device attitude data in real time 24 / 7 and continuously uploads it to the cloud platform. The cloud attitude recognition unit has a built-in threshold judgment algorithm, which presets the attitude parameter thresholds corresponding to each playback mode: when only a single panel is unfolded and the other panels are folded, and the angle deviation threshold is ≤10°, it is judged as a single-screen display condition, and the single-screen playback mode is automatically switched to drive only the unfolded panel to play the complete advertisement screen; when 2-5 panels are unfolded simultaneously and are in a semi-folded linkage state, and the panel angle is in the range of 30°-150°, it is judged as a multi-face linkage condition, and the multi-face linkage mode is automatically switched to achieve seamless display of multi-panel screens through faceted rendering model; when all 6 panels are fully unfolded to form a complete 3D cube structure, and the angle deviation of each panel is ≤5°, it is judged as a panoramic display condition, and the 3D panoramic mode is automatically switched to split rendering panoramic material to achieve 360° 3D advertisement display.

[0032] The entire mode switching process is fully automated, requiring no on-site manual operation. The cloud backend can record the device's posture status and playback mode information in real time, supporting remote viewing, manual fine-tuning, and parameter customization to adapt to special scenario display needs.

[0033] The foldable LED cube advertising screen integrated into this system can be deployed in outdoor commercial areas, outdoor exhibitions, cultural and tourism plazas, and other scenarios. After the device is powered on, it automatically completes posture self-checks and network connection, continuously uploading deformation posture data. Users can remotely upload advertising materials and issue placement commands through mobile phones or computer cloud backends. The system automatically adapts the image rendering method and playback mode according to the real-time folding shape of the device. Facing complex outdoor environments such as wind, rain, high and low temperatures, and vibration, the sensing module and screen can operate stably, with uninterrupted data transmission and distortion-free image display. There is no need for staff to conduct regular on-site debugging, significantly reducing the operation and maintenance costs of outdoor advertising, and the display effect is significantly improved compared to traditional fixed cube screens.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
