[0002] With the rapid development of LED display technology, its application in commercial displays, stage performances, and urban landscapes has become increasingly mature, primarily serving the functions of visual presentation and environmental beautification. In recent years, LED display technology has begun to extend into the field of sports venues. However, existing products are mostly limited to advertising screens, scoreboards, or simple ground ambient lighting devices around the venue. Their functional positioning remains at the level of visual output, failing to achieve substantial functional coupling and data interaction with sports itself, and thus unable to provide effective data support for athletes' training optimization, technical evaluation, or competition analysis.
[0003] In applications targeting professional sports training and competitive analysis, sports floor systems not only need high-quality display capabilities but also require real-time perception and quantitative feedback of athletes' athletic status. However, existing LED floor tile screen products have limited structural functionality, and the display and sensing modules lack effective integration design. If sensing functions are forcibly added, they often employ simple external or planar stacking combinations, resulting in limited sensing types and insufficient accuracy. Summary of the Invention

The mounting posts are connected to the shell body and project toward a base. The shell body has a bottom wall and sidewalls arranged circumferentially around the bottom wall. The shell body defines a first chamber. The sidewalls are configured as the surface walls of the first chamber. The circuit board is disposed in the first chamber. Along the direction from the force sensing layer to the force receiving layer, the distance from the lower surface of the force receiving layer to the upper surface of the base is greater than the distance from the upper surface of the circuit board layer to the upper surface of the base; and / or,
[0022] The ends of the sidewalls are higher than the surface of the circuit board.
[0023] In some embodiments, the mounting base includes a magnetic element, the base is magnetic, and the magnetic element and the base are magnetically connected; and / or,
[0024] The base has positioning protrusions, and the force sensing layer has positioning holes, with the positioning protrusions passing through the positioning holes.
[0025] An embodiment of the second aspect of this application proposes an intelligent floor screen, including a plurality of screen structures as described above, wherein the plurality of screen structures are connected in a horizontal direction.
[0026] In some embodiments, the circuit board layer includes a plurality of spaced-apart light-emitting elements and an infrared sensor, the infrared sensor being adapted to detect the height of the target object from the force-bearing layer and / or the position of the target object relative to the force-bearing layer.

[0036] According to the above embodiments, the beneficial effects of this application are:
[0037] The screen structure of this application includes a force-receiving layer, a circuit board layer, a force-conducting layer, a force-sensing layer, and a base. The force-receiving layer is adapted to contact a target object. The circuit board layer is located below the force-receiving layer, the force-conducting layer is located below the circuit board layer, and the force-sensing layer is located below the force-conducting layer. The force-sensing layer includes a pressure sensor and abuts against the force-conducting layer to monitor pressure from the force-conducting layer. The base is located below the force-sensing layer and is connected to the force-sensing layer. The force-receiving layer includes a mask structure and a force-conducting structure. Along the direction from the base to the force-receiving layer, the force-conducting structure has two oppositely arranged ends. The first end is connected to the mask structure, and the second end is connected to the force-conducting layer, so that the pressure from the mask structure is transmitted to the force-conducting layer. The circuit board layer has through-holes through which the force-conducting structure passes.
[0038] The screen structure of this application adopts a vertically integrated three-dimensional mechanical transmission architecture. A force transmission structure rigidly connects the mask structure of the force-bearing layer to the underlying force transmission layer, forming an efficient and direct force transmission path. The force transmission structure passes through vias in the circuit board layer, allowing the circuit board layer to float outside the force transmission path. This effectively isolates the direct impact of external impact loads on precision circuit components, reducing the risk of deformation, solder joint fatigue, and device failure caused by mechanical stress on the circuit board, thereby significantly improving the overall structural reliability and service life. Simultaneously, the direct contact between the force transmission layer and the force sensing layer ensures efficient pressure signal acquisition, reduces energy loss and signal attenuation during force transmission, and improves the sensitivity and accuracy of pressure monitoring.
[0039] This layered decoupled design not only achieves efficient spatial integration of display and sensing functions, but also ensures structural stability and durability under dynamic loads through precise force transmission in the vertical direction. The base provides a stable support foundation for the force sensing layer, and the mechanical coupling formed between the functional layers through the force transmission structure ensures effective force transmission while avoiding physical interference and signal crosstalk between functional modules in traditional planar stacked layouts. This structural design ensures high-precision pressure sensing while providing reliable mechanical protection for the circuit system, achieving an organic unity between sensing performance and structural strength. It is particularly suitable for dynamic application scenarios that require withstanding high-frequency, high-load impacts. For example, during basketball, the athlete's continuous jumps and landings, sudden stops and changes of direction, and the repeated impacts of the basketball during dribbling all apply transient high loads to the surface of the screen. The force transmission structure directly transmits the impact force borne by the mask structure to the force transmission layer and the force sensing layer through rigid connection, realizing efficient transmission and accurate acquisition of impact energy. At the same time, the suspended protection design of the circuit board layer effectively isolates the damage of severe vibration to electronic components, ensuring the long-term stable operation of display and sensing functions under high-intensity confrontation environment.

[0080] The realization of the purpose, functional features and advantages of this application will be further explained with reference to the accompanying drawings and embodiments. Detailed Implementation
[0081] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0082] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0083] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
[0084] In related technologies, precision circuit boards directly participate in mechanical load bearing or are on the impact transmission path. This not only fails to protect electronic components from damage by dynamic loads, but also causes pressure transmission to be dispersed and distorted, and response to be delayed. It is difficult to meet the professional needs of fine monitoring of biomechanical parameters such as athletes' force characteristics, center of gravity movement, and movement trajectory, which seriously restricts the in-depth application and value release of LED display technology in the field of smart sports.
[0085] The following is for reference. Figures 1 to 29 This application describes a screen structure, smart floor screen, monitoring method, medium, and computer product according to embodiments of the present application. (Refer to...) Figures 1 to 6Some embodiments of this application propose a screen structure 10, which includes a force-receiving layer 100, a circuit board layer 200, a force-conducting layer 300, a force-sensing layer 500, and a base 600. The force-receiving layer 100 is adapted to contact a target object. The circuit board layer 200 is disposed below the force-receiving layer 100, the force-conducting layer 300 is disposed below the circuit board layer 200, and the force-sensing layer 500 is disposed below the force-conducting layer 300. The force-sensing layer 500 includes a pressure sensor 520 and abuts against the force-conducting layer 300 to monitor pressure from the force-conducting layer 300. The base 600 is disposed below the force-sensing layer 500 and is connected to the base 600. The force-bearing layer 100 includes a mask structure and a force-transmitting structure 120. Along the direction from the base 600 to the force-bearing layer 100, the force-transmitting structure 120 has two oppositely arranged ends. The first end is connected to the mask structure, and the second end is connected to the force-transmitting layer 300, so that the pressure of the mask structure is transmitted to the force-transmitting layer 300. The circuit board layer 200 has a through hole 230, and the force-transmitting structure 120 passes through the through hole 230.
[0086] Reference Figure 2 The screen structure 10 of this application adopts a vertically integrated three-dimensional mechanical transmission architecture. The force transmission structure 120 rigidly connects the mask structure of the force-bearing layer 100 to the underlying force transmission layer 300, forming an efficient and direct force transmission path. The force transmission structure 120 passes through the through-holes 230 of the circuit board layer 200, allowing the circuit board layer 200 to float outside the force transmission path. This effectively isolates the direct impact of external impact loads on precision circuit components, reducing the risk of deformation, solder joint fatigue, and device failure of the circuit board 210 due to mechanical stress, thereby significantly improving the overall structural reliability and service life. Simultaneously, the direct contact between the force transmission layer 300 and the force sensing layer 500 ensures efficient pressure signal acquisition, reduces energy loss and signal attenuation during force transmission, and improves the sensitivity and accuracy of pressure monitoring.
[0087] This layered decoupled design not only achieves efficient integration of display and sensing functions in spatial layout, but also ensures the stability and durability of the structure under dynamic loads through precise force transmission in the vertical direction. The base 600 provides a stable support foundation for the force sensing layer 500. The mechanical coupling between functional layers through the force transmission structure 120 ensures effective force transmission while avoiding physical interference and signal crosstalk between functional modules in traditional planar stacked layouts. This structural design ensures high-precision pressure sensing while providing reliable mechanical protection for the circuit system, achieving an organic unity between sensing performance and structural strength. It is particularly suitable for dynamic application scenarios requiring high-frequency, high-load impacts. For example, during basketball, the athlete's continuous jumps and landings, sudden stops and changes of direction, and the repeated impacts of the basketball during dribbling all apply transient high loads to the surface of the screen. The force transmission structure 120 directly transmits the impact force borne by the mask structure to the force transmission layer 300 and the force sensing layer 500 through a rigid connection, realizing efficient transmission and accurate acquisition of impact energy. At the same time, the suspended protection design of the circuit board layer 200 effectively isolates the damage of severe vibration to electronic components, ensuring the long-term stable operation of the display and sensing functions under high-intensity confrontation environment.
[0088] In some embodiments, the force-bearing layer 100 refers to the functional layer located at the top of the screen structure 10, directly in contact with the external environment and bearing external loads. It includes a mask structure and a force transmission structure 120 for receiving and transmitting mechanical pressure downwards. In some embodiments, the force-bearing layer 100 can be configured as a composite load-bearing system including the mask structure and the force transmission structure 120. The mask structure can be an integral cover panel or a modular cover plate with a split array layout. The force transmission structure 120 can be set as a through-type column, cantilever support, or grid-like force transmission support. The two work together to form the interface for receiving and transmitting surface loads. Specifically, the mask structure can directly serve as the contact interface between the athlete's foot and the sports equipment. The force transmission structure 120 provides vertical support anchor points for the mask and transmits the mechanical load applied to the surface downwards to the force sensing layer 500, forming a complete mechanical transmission path.
[0089] Regarding the target object, it should be noted that the target object refers to the external entity that makes physical contact with the force-bearing layer 100 and applies pressure to the screen structure 10. In the specific application scenario of the sports floor screen, the target object mainly includes the body parts of athletes (such as feet) and sports balls such as basketballs, badminton shuttlecocks, and tennis balls. The contact, movement, and pressure application between the target object and the force-bearing layer 100 constitute the physical basis for structural mechanics transmission and sensing monitoring, enabling the system to perceive the position, height changes, and pressure distribution information of the target object.
[0090] Regarding the circuit board layer 200, in some embodiments, the circuit board layer 200 is a functional layer disposed below the force-bearing layer 100, having through holes 230 through which the force transmission structure 120 passes, allowing the circuit board layer 200 to float outside the force transmission path. In some embodiments, the circuit board layer 200 can be configured as a functional electronic layer carrying light-emitting elements 211 and sensing elements, specifically manifested as a printed circuit board 210 assembly carrying display driving circuits and signal processing circuits, or a composite circuit unit integrating a light-emitting array and an infrared sensing device. In addition, the circuit board layer 200 may include a mounting base 220 with a cavity structure. The mounting base 220 provides physical protection space for the internal circuit board 210 through surrounding sidewalls 221, and achieves mechanical anchoring with the lower structure through mounting posts 223 protruding towards the base 600, thereby forming a unified whole of electronic function implementation and structural support and protection, ensuring the stable operation of precision electronic devices in complex mechanical environments.
[0091] Regarding the force transmission layer 300, in some embodiments, the force transmission layer 300 is an intermediate force transmission structure disposed below the circuit board layer 200, used to receive pressure from the upper force transmission structure 120 and transmit it downward to the force sensing layer 500. The force transmission layer 300 can be configured as a load transfer component with composite functions, such as a load-bearing plate, a force transmission frame, or a grid-type support structure. In some embodiments, the force transmission layer 300 is provided with mounting points for anchoring the force transmission structure 120 and detection bosses for concentrating stress transmission. Load is received through mechanical coupling between the mounting points and the upper force transmission structure 120, and pressure is transmitted through direct contact between the detection bosses and the lower force sensing layer 500. In addition, the force transmission layer 300 can also integrate an elastic buffer medium to form a composite force transmission unit, or use an array of force transmission columns and connecting ribs to form a grid-like load-bearing system, thereby ensuring mechanical transmission efficiency while achieving coordinated cooperation with surrounding components.
[0092] Regarding the force sensing layer 500, in some embodiments, the force sensing layer 500 is a functional layer disposed below the force transmission layer 300 and connected to the base 600. The core component of the force sensing layer 500 includes a pressure sensor 520. The force sensing layer 500, through direct contact with the force transmission layer 300, realizes the sensing and monitoring of pressure from the force transmission layer 300. As the end sensing unit of the mechanical transmission path, the force sensing layer 500 converts the surface mechanical load transmitted step by step through the force transmission structure 120 and the force transmission layer 300 into a quantifiable electrical signal output, thereby completing the accurate acquisition of external pressure information. The sensing element of the force sensing layer 500 can specifically be an array of pressure sensing units, a distributed sensing module, or an integrated detection pad, etc., to achieve synchronous acquisition of surface pressure distribution through a multi-point sensor group, or to form surface contact with the force transmission layer 300 using an integrated molded sensing plane, thereby converting mechanical deformation into a measurable electrical signal. In some embodiments, the force sensing layer 500 may include a flexible substrate or a rigid support plate that carries the sensing element, on which signal transmission lines are laid and mechanically anchored to the base 600 to form a complete pressure sensing and signal output system.
[0093] In some embodiments, the two ends of the force transmission structure 120 refer to the mechanical connection ends arranged opposite each other along the direction from the base 600 to the force-bearing layer 100. These two ends can be the axial end faces of rod-shaped members, or can be manifested as various structural forms such as snap-fit joints, threaded mating parts, plug-in fitting parts, or integrally formed transition connection areas. The first end forms a mechanical connection with the mask structure to bear the surface load, and the second end forms a mating with the force transmission layer 300 to transmit pressure downward. The two ends together form a continuous force transmission path that penetrates the circuit board layer 200 and bypasses its through-hole 230 space, ensuring that the mechanical transmission from the force-bearing layer 100 to the force transmission layer 300 is not blocked by intermediate layers, realizing efficient acquisition of pressure signals and effective isolation of the circuit board layer 200.
[0094] In some embodiments, the through-holes 230 provided in the circuit board layer 200 can be regular circular or rectangular through-holes 230 specifically provided for the force transmission structure 120 to ensure precise alignment and stable fit of the force transmission path; or they can be irregular avoidance patterns designed to adapt to complex assembly relationships, thereby ensuring mechanical transmission efficiency while also optimizing the layout of the circuit board layer 200. Furthermore, the through-holes 230 can also be in the form of a grid array to match the distributed arrangement requirements of multiple force transmission structures 120, enabling synchronous multi-point pressure acquisition. In application scenarios where the circuit board layer 200 is composed of multiple sub-boards, the splicing gaps can be directly used as passageways for the force transmission structure 120, achieving three-dimensional transmission function without additional processing, effectively simplifying the manufacturing process and improving the overall integration of the structure.
[0095] Reference Figure 2 , Figures 12 to 16 In some embodiments, the force transmission structure 120 is configured as a rod, with its length parallel to the direction from the base 600 to the force-bearing layer 100, to optimize the accuracy and efficiency of force transmission. The rod-like configuration provides a clear and stable directional constraint for force transmission, enabling the pressure from the mask structure of the force-bearing layer 100 to be efficiently transmitted axially to the force transmission layer 300, minimizing force dispersion and loss during transmission and ensuring accurate capture of pressure signals by the force sensing layer 500. Simultaneously, the vertical arrangement is highly compatible with the overall layered architecture, allowing the force transmission structure 120 to maintain a perpendicular relationship to the board surface when penetrating the through-hole 230 of the circuit board layer 200. This minimizes the space occupied by the through-hole 230 on the layout of the circuit board layer 200 and avoids lateral force components and structural interference problems that may be caused by oblique or curved force transmission paths.
[0096] Specifically, the force transmission structure 120 is configured as a rod, i.e., this application adopts a lattice-type discrete force transmission architecture. For example, the array-arranged force transmission structure 120 transforms the continuous surface load on the mask structure into concentrated force transmission at 256 independent points. Compared with the planar uniform force transmission mode of traditional integral masks, this point-like transmission mechanism effectively avoids the dispersion, attenuation, and lateral crosstalk of force flow at the interface of multi-layer structures, enabling the pressure signal to be accurately transmitted vertically to the corresponding detection position 320 of the force sensing layer 500. This significantly improves the spatial resolution and numerical accuracy of pressure detection, and achieves precise capture of refined biomechanical parameters such as the trajectory of the athlete's foot pressure center and the forefoot / heel force ratio.
[0097] Furthermore, the regular geometric shape of the rod-shaped force transmission structure 120 provides a reliable guarantee for the fitting accuracy with adjacent components. This shape facilitates positioning and connection with the mask structure and force transmission layer 300, ensuring assembly consistency and repeatability, and improving structural stability during mass production. The vertical arrangement also ensures that the force transmission structure 120 is primarily under axial compression when subjected to dynamic impact loads, fully utilizing the compressive strength of the rod material and effectively suppressing the risk of bending deformation and lateral instability, thereby maintaining a constant and reliable force transmission path under long-term vibration conditions. This design achieves efficient mechanical function with a simple configuration, laying an important foundation for the overall compactness and high performance of the screen structure 10.
[0098] Regarding the force transmission structure 120, further, in some embodiments, a hollow tubular structure can be adopted, with the tube wall bearing the axial pressure. The internal cavity can provide space for wiring or other functional components, achieving dual optimization of force transmission and functional integration. In some embodiments, a variable cross-section stepped shaft structure can be adopted, with differentiated radial dimensions set in different height sections to adapt to the thickness differences and connection requirements of each functional layer, forming a gradual force flow transition. In some embodiments, a combined sleeve structure can be adopted, with an inner rod and an outer sleeve forming a nested fit. The inner rod undertakes the main force transmission function, while the outer sleeve provides lateral constraints and positioning guidance. The two work together to achieve precise force transmission and adjustable assembly.
[0099] Reference Figure 5 , Figure 15 and Figure 16 In some embodiments, the force transmission layer 300 has an installation position 310 and a detection position 320. At the installation position 310, the force-bearing layer 100 is installed. The detection position 320 has a detection block protruding towards the force-sensing layer 500, with the end of the detection block abutting against the force-sensing layer 500 so that the force-sensing layer 500 can detect pressure from the force-bearing layer 100. By setting functional partitions between the installation position 310 and the detection position 320, precise separation and coordinated operation of structural connection and pressure detection are achieved. The installation position 310 provides a stable mechanical anchor point for the force-bearing layer 100, ensuring a reliable connection between the force transmission structure 120 and the force transmission layer 300, allowing external loads to be effectively transmitted to the overall structure of the force transmission layer 300. The protruding detection block of the force-sensing layer 500 at the detection position 320 constitutes a targeted pressure concentration transmission unit. The abutting design of its end with the force-sensing layer 500 forms a direct force contact interface, avoiding pressure dispersion and attenuation during transmission. This functional zoning design ensures that structural installation and signal acquisition do not interfere with each other, guaranteeing the stability of mechanical connections while optimizing the sensitivity and accuracy of pressure detection.
[0100] Furthermore, the protruding configuration of the detection block shortens the pressure transmission path, allowing pressure from the load-bearing layer 100 to act directly and efficiently on the force sensing layer 500 through the detection block, reducing force loss and response delay in intermediate stages. Simultaneously, the interface between the detection block and the force sensing layer 500 can be specifically designed according to detection requirements to optimize pressure distribution and improve detection accuracy. The layout of the installation position 310 and the detection position 320 can be flexibly configured according to sensing density and structural strength requirements, achieving multi-point distributed pressure monitoring while ensuring overall structural rigidity. This design, with its simple functional zoning strategy, effectively coordinates the dual needs of structural load-bearing and sensing detection, giving the force transmission layer 300 a clear mechanical orientation and functional specificity, and improving the reliability and monitoring effectiveness of the screen structure 10 under complex working conditions.
[0101] Regarding the installation position 310 and the detection position 320, in some embodiments, a concentric ring layout is adopted, with the installation position 310 set as an annular area surrounding the detection position 320, and the detection block located at the center. This layout facilitates the synergy between centralized central pressure detection and stable external anchoring, improving the overall stability and detection symmetry of the structure. In some embodiments, an interlaced array layout can be adopted, with multiple installation positions 310 and detection positions 320 alternately arranged along the surface of the force transmission layer 300 to form a grid distribution. This design can achieve multi-point distributed pressure acquisition while ensuring structural connection density, and is suitable for large-area sensing coverage scenarios. In some embodiments, a hierarchical nested layout can be adopted, with the installation positions 310 and detection positions 320 layered in the thickness direction of the force transmission layer 300. The upper layer is the installation position 310 to achieve a fitting connection with the force-bearing layer 100, and the lower layer protrudes to form a detection block to fit against the force sensing layer 500. This three-dimensional layout effectively separates the mechanical connection interface and the pressure transmission interface, avoiding interference from assembly stress on detection accuracy.
[0102] The protruding surface of the detection block is suitable for the pressure sensor 520 of the stress sensing layer 500. Therefore, the shape of the detection block can be flexibly arranged according to the distribution of the pressure sensor 520. In some embodiments, a frustum-shaped detection block can be used, with its gradually expanding sidewalls 221 forming a gradual diffusion of force flow, increasing the contact area with the force sensing layer 500, reducing contact stress concentration, and maintaining structural continuity with the force transmission layer 300 body. In some embodiments, a spherical cap-shaped detection block can be used, utilizing its smooth convex surface to form point or line contact with the force sensing layer 500, realizing adaptive adjustment of the pressure direction and reducing detection deviation caused by assembly errors or force skew. In some embodiments, a bifurcated detection block can be used, splitting into multiple sub-contact portions at the end. Each sub-contact portion can be independently attached to different sensitive units of the force sensing layer 500, realizing pressure distribution from a single force transmission structure 120 to multiple detection points, improving spatial resolution and redundancy reliability.
[0103] It is understandable that the installation location is only for installation and does not bear any force from the load-bearing face shield 110. For details, please refer to... Figures 7 to 10The screen structure of this application adopts a layered and decoupled floating design, which creates a non-contact spatial separation between the circuit board layer 200 and the force-bearing layer 100, achieving physical isolation between precision electronic components and the dynamic force transmission path. Along the direction from the force-sensing layer 500 to the force-bearing layer 100, the distance from the lower surface of the force-bearing layer 100 to the upper surface of the base 600 is greater than the distance from the upper surface of the circuit board layer 200 to the upper surface of the base 600. This height difference limits the overall suspension of the circuit board layer 200 below the force-bearing layer 100, forming a controllable gap space between them. In some embodiments, the vertical distance between the upper surface of the circuit board layer 200 and the lower surface of the force-bearing layer 100 is 0.2 mm. This gap size ensures that the deformation displacement of the force-bearing layer 100 under external loads will not touch the circuit board layer 200, and also provides the necessary physical space for the heat dissipation, wiring, and electromagnetic shielding functions of the circuit board layer 200. The floating state of the circuit board layer 200 is structurally supported by the mounting posts 223 of the mounting base 220. Mounting post 223 connects to the shell body and protrudes towards the base 600, forming a rigid anchor with the base 600, so that the shell body and the first chamber it defines are suspended above the base 600. The end of the side wall 221 is higher than the surface of the circuit board 210, forming a circumferential physical barrier to the internal electronic components, preventing foreign objects from the side from intruding or accidentally touching it, further enhancing the suspension protection effect of the circuit board layer 200 under dynamic load environment. The force transmission structure 120 passes through the through hole 230 of the circuit board layer 200, maintaining a non-contact or micro-gap fit with the hole wall of the through hole 230. This insertion method allows the force transmission structure 120 to form a clear functional partition with the circuit board layer 200 during its penetration of the circuit board layer 200. For example, the force transmission structure 120 constitutes an independent force transmission channel, and the circuit board layer 200 is completely suspended outside this force transmission path. The external load on the load-bearing layer 100 is completely transmitted to the force transmission layer 300 and the force sensing layer 500 through the force transmission structure 120. The circuit board layer 200 does not participate in any mechanical load-bearing, thereby eliminating the diversion, attenuation or interference effect on the pressure transmission path caused by the circuit board layer 200's own stiffness, deformation characteristics or assembly state differences.
[0104] In summary, the suspended design ensures that the circuit board layer 200 remains stress-free in dynamic application scenarios where the screen structure 10 is subjected to high-frequency, high-load impacts. Taking basketball as an example, the transient high loads generated by athletes' continuous jumps, landings, sudden stops, changes of direction, and dribbling impacts are directly transmitted to the force sensing layer 500 via the rigid force transmission structure 120. The suspended protection design of the circuit board layer 200 effectively isolates the electronic components from severe vibrations, ensuring the long-term stable operation of the display and sensing functions. At the same time, this suspended gap provides ample space and assembly freedom for the force transmission structure 120, enabling the three-dimensional transmission path and electronic display functions to achieve efficient collaboration and non-interference within a limited spatial dimension.
[0105] Reference Figures 1 to 6 In some embodiments, the force transmission structure 120 abuts against the detection position 320. In some embodiments, the screen structure 10 includes an elastic buffer layer 400 sandwiched between the force transmission layer 300 and the force sensing layer 500. Specifically, through the direct abutment design between the force transmission structure 120 and the detection position 320, and the sandwich arrangement between the elastic buffer layer 400, the force transmission layer 300, and the force sensing layer 500, a dual optimization of pressure transmission accuracy and system buffer protection is achieved. The direct abutment of the force transmission structure 120 against the detection position 320 forms a rigid force transmission path, allowing the pressure from the force-bearing layer 100 to be transmitted to the detection block without loss, and then act on the force sensing layer 500, improving the sensitivity and response speed of pressure detection, and avoiding signal attenuation and delay caused by loosening or gaps in intermediate links. At the same time, this direct abutment relationship simplifies the assembly structure, reduces the number of connecting parts, and enhances the reliability and long-term working stability of the force transmission path. The introduction of the elastic buffer layer 400 provides the screen structure 10 with controllable deformation capability and energy absorption mechanism. This buffer layer, sandwiched between the force transmission layer 300 and the force sensing layer 500, can absorb and buffer some energy through elastic deformation when subjected to dynamic impact loads, effectively reducing the direct damage of transient impact forces to the force sensing layer 500 and protecting the precision sensing elements from overload damage. Simultaneously, the elastic properties of the buffer layer create a flexible contact interface between the force transmission layer 300 and the force sensing layer 500, achieving a smooth transition and optimized distribution of force during pressure transmission, reducing stress concentration problems that may be caused by hard contact. In summary, this design ensures both accurate and efficient pressure detection and improves the durability and reliability of the structure under complex working conditions, achieving a harmonious balance between mechanical performance and protective functions.
[0106] Furthermore, the elastic buffer layer 400 can adopt various forms to achieve buffering and force transmission functions. For example, in some embodiments, the elastic buffer layer 400 can adopt a continuous homogeneous layered structure, covering the force sensing layer 500 with an overall flat interface, providing uniform support and comprehensive buffer protection for the force transmission layer 300. In some embodiments, the elastic buffer layer 400 can adopt a local boss array structure, with elastic units protruding towards the force transmission layer 300 at specific locations, achieving targeted buffer support and providing clearance space or forming a mating relationship for the detection block. In some embodiments, the elastic buffer layer 400 can adopt a corrugated or toothed interlocking structure, enhancing interlayer shear stability through geometric interlocking at the interface, while providing multi-directional buffering capability through the undulating deformation of the corrugations. In some embodiments, the elastic buffer layer 400 can adopt a partitioned composite structure, setting the buffer stiffness differently for the load characteristics of different regions, achieving local optimization and overall coordination of mechanical response.
[0107] Reference Figures 1 to 6 as well as Figure 15 In some embodiments, at least a portion of the force transmission structure 120 is installed at the installation position 310. Directly installing at least a portion of the force transmission structure 120 at the installation position 310 of the force transmission layer 300 enhances the integrity of the force transmission path and the compactness of the structural assembly. By embedding or fixing the lower end of the force transmission structure 120 to the installation position 310, a continuous rigid force transmission channel is formed from the mask structure of the force-bearing layer 100 to the force transmission layer 300, effectively avoiding force transmission loss and response delay caused by fit gaps or loose connections between multi-layer structures. This installation method allows the force transmission structure 120 to receive direct support and constraint from the force transmission layer 300 when bearing external loads, suppressing the swaying and deflection of the force transmission components under dynamic working conditions, and ensuring the stability and accuracy of the pressure transmission direction. Simultaneously, the direct fit between the force transmission structure 120 and the installation position 310 simplifies the overall assembly relationship, reduces the use of intermediate transition connectors, and lowers the cumulative tolerance in the structural height direction, which is beneficial for achieving a thinner design of the screen structure 10. This installation layout also allows the force transmission layer 300 to perform both force transmission and load-bearing functions. Its main structure serves as an extension and anchoring foundation for the force transmission structure 120, enhancing the overall rigidity and impact resistance of the structure. Furthermore, the selective arrangement of the force transmission structure 120 at installation position 310 provides flexibility in configuring the sensing density. The appropriate number of force transmission structures 120 can be placed at different locations according to monitoring accuracy requirements, achieving synergistic optimization of structural strength and sensing performance. This design achieves efficient mechanical integration through a simple assembly relationship, laying an important foundation for the modular production and reliable operation of the screen structure 10.
[0108] In some embodiments, the lower end of the force transmission structure 120 can be directly installed at the installation position 310 to form a rigid force transmission channel, or an independent connecting component can be set at the installation position 310 to achieve mechanical anchoring between the load-bearing layer 100 and the force transmission layer 300. In this case, the force transmission structure 120 can only abut against or approach the detection position 320 without directly participating in the connection of the installation position 310. In the latter layout, the installation position 310 mainly undertakes the structural fixing function between the load-bearing layer 100 and the force transmission layer 300, ensuring the relative position stability of the two under dynamic loads. The detection position 320 independently forms a close contact with the force sensing layer 500 through the detection block for pressure signal acquisition and transmission. This functional separation design allows structural connection and pressure detection to be implemented by different components, avoiding the interference of assembly stress on detection accuracy. At the same time, it provides greater design space for layout optimization of the force transmission structure 120 and flexible configuration of sensing density, which is beneficial for targeted trade-offs and coordinated optimization of structural strength and detection sensitivity according to specific application scenarios.
[0109] Reference Figure 5 and Figure 15 In some embodiments, the end of the force transmission structure 120 facing the force sensing layer 500 has a threaded hole, the mounting position 310 has a through hole 230, and the screen structure 10 includes a threaded fastener 700, which passes through the through hole 230 and is threaded to the threaded hole. By using an assembly method in which the threaded fastener 700 passes through the through hole 230 of the mounting position 310 and is threadedly connected to the threaded hole at the end of the force transmission structure 120, a detachable rigid fixation between the force transmission structure 120 and the force transmission layer 300 is achieved. The threaded connection structure provides a reliable axial tightening force, enabling the force transmission structure 120 to be stably anchored at the mounting position 310, maintaining a constant position under dynamic impact loads, effectively suppressing the loosening, dislodgement, or relative slippage of the force transmission component, and ensuring the long-term stability and repeatability of the pressure transmission path. At the same time, the preload of the threaded connection can be adjusted according to assembly requirements, achieving controllable optimization of the connection stiffness, ensuring sufficient tightening strength to resist vibration conditions, and avoiding structural deformation or stress concentration problems caused by over-tightening. Furthermore, the detachable threaded connection enhances the assembly convenience and maintenance efficiency of the screen structure 10. The standardized design of the threaded fastener 700 facilitates mass production and quality control, while the corresponding arrangement of the through hole 230 and the threaded hole simplifies assembly alignment, enabling rapid modular assembly. During long-term use, if the force transmission structure 120 or adjacent components experience wear, aging, or functional abnormalities, individual replacement can be achieved by unscrewing the threaded fastener 700, without damaging the overall structure or performing complex disassembly, significantly reducing maintenance costs and downtime. Moreover, the reversibility of the threaded connection provides conditions for structural debugging, optimization, and upgrades. The arrangement density or connection parameters of the force transmission structure 120 can be flexibly adjusted based on actual operational feedback, enhancing the screen structure 10's adaptability to different application scenarios and its economic feasibility throughout its entire lifecycle.
[0110] Regarding the connection method of the force transmission structure 120, in some embodiments, a plug-in snap-fit structure can be adopted, with radial lugs or barbs provided at the end of the force transmission structure 120, and corresponding slots or reduced-diameter holes provided at the mounting position 310. A quick, tool-free connection is achieved through axial insertion and rotational locking, balancing assembly efficiency and connection reliability. In some embodiments, a magnetic adhesion structure can be adopted, with magnetic elements embedded at the end of the force transmission structure 120 and corresponding to the mounting position 310. Magnetic force is used to achieve adsorption positioning and pre-tightening between the two. This method facilitates quick assembly and disassembly and has a certain self-centering capability, suitable for scenarios requiring frequent maintenance or adjustment. In some embodiments, an interference fit structure can be adopted, where a tight friction connection is formed through dimensional interference fit between the end of the force transmission structure 120 and the hole at the mounting position 310 using a press-fit process. This method has a simple structure, requires no additional connecting parts, and facilitates a compact and lightweight design of the overall structure.
[0111] Reference Figure 5 and Figure 15 In some embodiments, the mounting position 310 surrounds the detection position 320. This arrangement ensures that the detection block receives balanced support and constraint from the surrounding mounting positions 310 when subjected to pressure, effectively suppressing warping or skew deformation of the detection position 320 under load. This allows pressure to be transmitted vertically and stably to the force sensing layer 500, improving the accuracy and repeatability of the detection. Simultaneously, the surrounding mounting positions 310 provide multi-point mechanical anchoring for the force transmission structure 120, enhancing the circumferential uniformity and overall stability of the connection between the force transmission layer 300 and the load-bearing layer 100, and reducing the risk of local stress concentration. Furthermore, this concentric arrangement provides good structural symmetry, enabling the force transmission layer 300 to maintain a balanced and stable mechanical response when subjected to eccentric loads or dynamic impacts, which is beneficial for improving the reliability and durability of the screen structure 10 under long-term vibration conditions.
[0112] Reference Figures 12 to 16 In some embodiments, the direction from the base 600 to the force-bearing layer 100 is the first direction, and the force transmission structures 120 are arranged at intervals along the second direction. In some embodiments, the force transmission structures 120 are arranged at intervals along a third direction, and the first, second, and third directions are perpendicular to each other. By arranging multiple force transmission structures 120 in an array in the horizontal plane, a multi-dimensional pressure acquisition network is formed, enabling the screen structure 10 to simultaneously monitor the pressure status at multiple locations, effectively capturing the position, distribution pattern, and dynamic changes of the target object on the surface of the force-bearing layer 100. This interval arrangement breaks through the limitations of a single force transmission point, providing spatial information richness for pressure monitoring, which is beneficial for achieving refined analysis of the target object's motion trajectory, posture balance, and mechanical characteristics. At the same time, the planar arrangement perpendicular to the first direction ensures that each force transmission structure 120 does not interfere with each other when transmitting force vertically, forming independent and parallel mechanical channels, thus ensuring the synchronization and accuracy of multi-point pressure detection.
[0113] Reference Figures 7 to 10 In some embodiments, the circuit board layer 200 and the load-bearing layer 100 are spaced apart. This spaced arrangement of the circuit board layer 200 and the load-bearing layer 100 achieves spatial separation and mutual protection between the display function and the mechanical load-bearing function. This spacing ensures that when the load-bearing layer 100 is subjected to external impact or pressure, its deformation or displacement will not be directly transmitted to the circuit board layer 200, effectively isolating dynamic loads from mechanical damage to precision electronic components and improving the reliability and service life of the circuit board layer 200 under vibration and impact conditions. Simultaneously, this spacing provides the necessary physical space for the circuit board layer 200 to perform functions such as heat dissipation, wiring, and electromagnetic shielding, which is beneficial for optimizing the operating environment and performance stability of the circuit board layer 200.
[0114] The spacing design also creates a clear functional division and collaborative relationship between the circuit board layer 200 and the force transmission structure 120. During its passage through the via 230 of the circuit board layer 200, the force transmission structure 120 maintains a non-contact or gap-fitting state with the circuit board layer 200, avoiding direct interference or frictional loss between the force transmission components and electronic components, ensuring the independence of the force transmission path and the integrity of the electrical performance of the circuit board layer 200. For example, this spacing ensures that the external load on the load-bearing layer 100 is completely transmitted to the force transmission layer 300 and the force sensing layer 500 via the force transmission structure 120, without the circuit board layer 200 participating in any mechanical load-bearing. This eliminates the diversion, attenuation, or interference effects on the pressure transmission path caused by differences in the circuit board layer 200's own stiffness, deformation characteristics, or assembly state, ensuring that the pressure signal received by the pressure sensing layer 500 accurately reflects the actual load on the target object, thus improving the accuracy and reliability of pressure detection.
[0115] Reference Figure 1 , Figure 17 and Figure 18In some embodiments, the circuit board layer 200 includes a circuit board 210 and a mounting base 220. The mounting base 220 includes a shell body and mounting posts 223. The mounting posts 223 are connected to the shell body and protrude toward the base 600. The shell body has a bottom wall and sidewalls 221 arranged circumferentially around the bottom wall. The shell body defines a first chamber. The sidewalls 221 are configured as the surface walls of the first chamber. The circuit board 210 is disposed in the first chamber. Along the direction from the force sensing layer 500 to the force receiving layer 100, the distance from the lower surface of the force receiving layer 100 to the upper surface of the base 600 is greater than the distance from the upper surface of the circuit board layer 200 to the upper surface of the base 600. In some embodiments, the end of the sidewall 221 is higher than the surface of the circuit board 210. Through the coordinated design of the shell body 220 and the mounting post 223, and the differentiated arrangement of the stress-bearing layer 100 and the circuit board layer 200 relative to the base 600, the sunken protection of the circuit board layer 200 and the optimized integration of the three-dimensional mechanical transmission structure are achieved. The mounting post 223 protrudes towards the base 600 and is directly connected to the base 600, so that the shell body and the first chamber it defines are suspended above the base 600, forming an independent housing space for the circuit board layer 200. The distance from the lower surface of the stress-bearing layer 100 to the upper surface of the base 600 is greater than the distance from the upper surface of the circuit board layer 200 to the upper surface of the base 600, ensuring that the circuit board layer 200 is completely below the stress-bearing layer 100 in the height direction. This prevents the deformation or displacement of the stress-bearing layer 100 under external loads from touching the circuit board layer 200, effectively avoiding mechanical interference and electrical damage. Meanwhile, the design of the sidewall 221 being higher than the surface of the circuit board 210 further strengthens the circumferential protection of the circuit board layer 200, forming a physical barrier for the internal electronic components and preventing the intrusion of foreign objects or accidental contact from the side. This design not only ensures the operational safety of the circuit board layer 200 under dynamic loads, but also provides ample space and assembly freedom for the force transmission structure 120, enabling the three-dimensional transmission path and electronic display functions to achieve efficient collaboration and non-interference within a limited spatial dimension, thereby improving the integration and reliability of the screen structure 10.
[0116] Regarding the connection method between the circuit board 210 and the assembly base 220, in some embodiments, a screw fastening connection is used. Through holes 230 are opened at the corners and center of the circuit board 210, and threaded holes or embedded nuts are provided corresponding to the bottom wall of the main body. The circuit board 210 is rigidly pressed and fixed by screwing in the screws. This method of connection is reliable and convenient to disassemble and assemble, and is suitable for scenarios with high requirements for connection strength. In some embodiments, a snap-fit connection is used. Elastic claws or barbs are provided on the inner side of the side wall 221, and notches or grooves are opened on the edge of the circuit board 210. The circuit board 210 is pressed into the cavity and is elastically locked by the claws, realizing tool-free quick assembly, which is beneficial to improving production efficiency and maintenance convenience. In some embodiments, a guide rail sliding connection is used. Parallel guide rail grooves are provided on the inner side of the oppositely arranged side walls 221. Thin flanges are formed on both sides of the circuit board 210. After sliding into the positioning position along the guide rail groove, it is limited by the end stop. This method facilitates the precise alignment of the circuit board 210 and the pull-out disassembly and assembly, and is suitable for application scenarios that require frequent replacement or debugging of the circuit board 210.
[0117] Reference Figure 11 In some embodiments, the assembly base 220 includes a magnetic element 222, and the base 600 is magnetic, with the magnetic element 222 and the base 600 magnetically connected. In some embodiments, the base 600 has a positioning protrusion 610, and the force sensing layer 500 has a positioning hole 510, through which the positioning protrusion 610 passes. Through the magnetic connection between the assembly base 220 and the base 600, and the through-and-through cooperation of the positioning protrusion 610 of the base 600 and the positioning hole 510 of the force sensing layer 500, rapid assembly and precise positioning between the functional layers of the screen structure 10 are achieved. The magnetic connection method utilizes magnetic attraction to achieve adsorption and fixation between the assembly base 220 and the base 600, achieving a reliable mechanical connection without the need for traditional threaded fasteners 700, significantly simplifying the assembly process, improving assembly efficiency, and facilitating non-destructive disassembly and reassembly during subsequent maintenance, reducing maintenance costs and operational difficulty. This magnetic connection also has a certain degree of self-adjustment capability, enabling preliminary alignment through magnetic guidance during assembly, creating conditions for subsequent precise positioning.
[0118] The engagement of the positioning protrusion 610 on the base 600 with the positioning hole 510 on the force sensing layer 500 provides a rigid positioning mechanism. The geometric fit between the protrusion and the hole restricts the translational and rotational freedom of the force sensing layer 500 relative to the base 600 in the horizontal plane, ensuring the accuracy and stability of the force sensing layer 500 at the installation position 310. This positioning structure effectively suppresses slippage or deflection of the force sensing layer 500 under dynamic loads, ensuring continuous alignment between the detection position 320 and the force transmission structure 120, thereby maintaining the accuracy and repeatability of pressure detection. The flexible adsorption of the magnetic connection and the rigid constraint of the positioning protrusion 610 complement each other, enabling both quick and convenient assembly operations and ensuring structural stability and reliable detection during long-term operation. This provides crucial technical support for the modular design and efficient maintenance of the screen structure 10.
[0119] Reference Figure 11 In some embodiments, the magnetic element 222 is disposed inside the mounting post 223. When the athlete jumps, the local pressure on the screen structure 10 increases sharply, causing the edges to easily lift. The adsorption capacity of the magnetic element 222 further ensures the stability of the connection between the circuit board layer 200 and the base 600.
[0120] Reference Figures 1 to 22 The second aspect of this application provides an intelligent floor screen, including a plurality of screen structures 10 as described above, with reference to... Figure 9 and Figure 12 and Figure 22Multiple screen structures 10 are connected horizontally. The smart floor screen provided in this application achieves a large-area, highly integrated motion monitoring and display platform by connecting and combining multiple of the aforementioned screen structures 10 horizontally. Each screen structure 10, as a standardized modular unit, has independent display driving and pressure sensing functions. Through horizontal splicing, it can be flexibly expanded to any required coverage area to adapt to the application needs of sports fields or interactive spaces of different sizes. The modular design ensures the functional integrity of a single screen structure 10. Each unit can operate independently to achieve localized pressure detection and display control, and can also work together to form a globally unified data acquisition and presentation system, significantly improving the system's scalability and configuration flexibility. This splicing architecture also gives the smart floor screen excellent maintenance convenience and operational reliability. When a screen structure 10 fails or needs to be upgraded, the unit can be disassembled, replaced, or debugged and repaired individually without interrupting the operation of the entire floor screen system, greatly reducing maintenance costs and downtime losses. Meanwhile, the standardized interfaces and consistent mechanical and electrical performance between each screen structure 10 ensure the overall flatness and functional continuity after splicing, avoiding monitoring blind spots or display discontinuities caused by differences in units. This design, with its modular system approach, extends the technological advantages of a single screen structure 10 to large-scale application scenarios, providing an efficient, reliable, and economical technical solution for building immersive, interactive smart sports spaces.
[0121] Reference Figure 3 In some embodiments, the circuit board layer 200 includes multiple spaced-apart light-emitting elements 211 and infrared sensors 212. The infrared sensors 212 are adapted to detect the height of the target object from the force-bearing layer 100 and / or the position of the target object relative to the force-bearing layer 100. Integrating multiple spaced-apart light-emitting elements 211 and infrared sensors 212 into the circuit board layer 200 of the smart floor screen achieves deep synergy and spatial reuse of display and optical sensing functions. The light-emitting elements 211 provide the floor screen with high-definition visual presentation capabilities, supporting real-time display of dynamic images, interactive feedback, and event information; the infrared sensors 212, through actively emitting and receiving infrared signals, achieve non-contact detection of the vertical height and horizontal position of the target object. This optoelectronic integrated design enables a single screen structure 10 to simultaneously possess both visual output and environmental perception capabilities, enhancing the information interaction dimension and scene adaptability of the smart floor screen.
[0122] Specifically, the infrared sensor 212's ability to detect the height of the target object enables the floor screen to recognize athletes' take-off and jumping movements, providing crucial data support for motion posture analysis and jumping ability assessment. Detecting the horizontal position of the target object allows for real-time tracking of the athlete's coordinates within the playing area, supporting advanced functions such as motion trajectory mapping, hotspot analysis, and multi-person interactive recognition. This multimodal sensing and display fusion design upgrades the smart floor screen from a simple passive display carrier into an interactive platform for active perception and intelligent analysis, providing strong technical support for digital sports training, immersive competitive experiences, and smart venue operation.
[0123] Reference Figure 29 The third aspect of this application provides a monitoring method for the screen structure 10 of any of the above claims. The monitoring method includes:
[0124] S101: The target object exerts pressure on the screen structure 10;
[0125] S103: Force sensing layer 500 detects pressure from the target object;
[0126] S105: Screen structure 10 outputs the first information.
[0127] The monitoring method proposed in this application achieves efficient conversion and accurate mapping of external mechanical action to digital information output through a series of steps: the target object applies pressure to the screen structure 10, the force sensing layer 500 detects the pressure, and the first information is output. In step S101, the target object applies mechanical load to the surface of the screen structure 10 through direct contact with the force-bearing layer 100. This pressure is directionally transmitted through the force transmission structure 120 and the force transmission layer 300, forming a clear and controllable mechanical input signal. This step defines the physical triggering conditions of the monitoring process, ensuring that only effective pressure that meets the threshold requirements can initiate the subsequent detection process, effectively filtering out invalid interference such as environmental micro-vibrations. In step S103, the force sensing layer 500, through contact with the force transmission layer 300, converts the received mechanical pressure into a quantifiable electrical signal. This step achieves sensitive capture and accurate conversion of mechanical quantities into electrical quantities, laying a data foundation for the digital characterization of pressure magnitude, distribution, and variation characteristics. In step S105, the screen structure 10 outputs the pressure information acquired by the force sensing layer 500 in the form of first information. This output can be expressed as pressure values, distribution images, trigger signals, or data formats that interface with other systems, realizing the visualization, storage, recording, or linkage control of the monitoring results. This step completes the closed loop from physical perception to information application, enabling the pressure monitoring function of the screen structure 10 to play a role in real-world scenarios. This monitoring method relies on the aforementioned three-dimensional mechanical transmission architecture of the screen structure 10, ensuring the high efficiency of pressure transmission and the accuracy of detection, providing reliable support for applications such as motion analysis, interactive control, and safety monitoring.
[0128] In some embodiments, after the step of the target object applying pressure to the screen structure 10, the monitoring method further includes:
[0129] At the first moment, the screen structure 10 obtains the distance from the target object to the force layer 100 and outputs the second information;
[0130] At the first moment, the screen structure 10 acquires the position of the target object relative to the force layer 100 and outputs the third information.
[0131] The monitoring method incorporates steps to simultaneously acquire the distance from the target object to the force-bearing layer 100 and output the second information, and to acquire the target object's position relative to the force-bearing layer 100 and output the third information. This achieves multi-dimensional information fusion and synchronous acquisition of pressure detection and spatial positioning. In the distance acquisition step, the screen structure 10 transmits a detection signal to the target object via infrared sensor 212 and receives the echo. Based on signal propagation time or intensity changes, the vertical distance between the target object and the force-bearing layer 100 is calculated. This step enables real-time perception of the target object's height status, identifying whether the athlete is in different postures such as airborne, landing, or standing, providing crucial third-dimensional data for motion trajectory analysis and biomechanical assessment. In the position acquisition step, the screen structure 10 determines the planar coordinates of the target object's projection onto the surface of the force-bearing layer 100 through signal difference analysis of the multi-point infrared sensor 212 or an array positioning algorithm. This step enables precise tracking of the target object's horizontal position, supporting applications such as motion path mapping, gait analysis, and regional hotspot statistics.
[0132] In some embodiments, the above two steps and the pressure detection step are executed simultaneously, ensuring the temporal synchronization of the mechanical and spatial states and avoiding data timing misalignment and correlation analysis failure caused by step-by-step acquisition. The synchronous output of the second and third information enables the monitoring method to construct a complete state description of the target object in three-dimensional space, expanding a single pressure value into a multi-dimensional data vector containing position, height, and force, thus enhancing the richness of information and its application value. This multimodal synchronous monitoring method, relying on the optoelectronic integrated design of the screen structure 10, provides comprehensive, accurate, and timely data support for intelligent motion analysis, real-time interactive feedback, and refined motion training through efficient signal processing and data fusion capabilities, promoting a leapfrog development of motion monitoring from single-point perception to spatial intelligence.
[0133] Furthermore, this application possesses significant application value and unique technical advantages in basketball player injury detection, posture analysis, and tactical simulation. For example, in injury detection, basketball involves frequent high-intensity movements such as jumping, sudden stops, and changes of direction. Athletes' knee joints, ankle joints, and plantar fascia bear enormous impact loads, which can easily lead to chronic injuries or acute trauma over time. The monitoring method of this application captures the pressure distribution characteristics and impact magnitude of the athlete's foot in real time through a pressure detection step, identifies jump height and landing posture through a distance detection step, and tracks the athlete's movement trajectory on the court through a position detection step, thus constructing a complete lower limb biomechanical load database. When the system detects that a player continuously exhibits asymmetrical pressure distribution, abnormal impact peaks, or unbalanced landing posture in a specific area, it can promptly warn of potential injury risks, prompting coaches to adjust training intensity or correct technical movements. In particular, the time synchronization characteristic of this method ensures strict correspondence between the pressure, height, and position data, accurately reconstructing the instantaneous biomechanical environment of the injury. This provides high-precision data for sports medicine teams to analyze injury mechanisms and develop rehabilitation plans, realizing a paradigm shift in injury management from passive treatment to proactive prevention.
[0134] In terms of posture analysis, traditional video analysis is limited by viewpoint occlusion and two-dimensional imaging, making it difficult to accurately quantify the athlete's center of gravity trajectory, force exertion sequence, and coordination of various body parts. This application, by simultaneously collecting data from multiple screen structures 10 arranged throughout the court, can reconstruct the athlete's three-dimensional kinematic model in real time: position information continuously tracks the athlete's planar movement path, identifying the angle of change of direction and movement speed; distance information dynamically reflects the athlete's center of gravity fluctuations, distinguishing different posture stages such as standing, knee bending, jumping, and airborne; pressure information accurately records the interaction force between the sole of the foot and the ground, revealing the mechanical characteristics of key techniques such as forefoot push-off and heel cushioning. Coaches can use this synchronous data to deeply analyze whether the athlete's shooting force chain is smooth, whether the defensive sliding step is stable, and whether the rebounding positioning is efficient, thereby developing targeted technical improvement plans. In addition, this method supports simultaneous monitoring and differentiation of multiple players, providing a data foundation for the posture coordination analysis at the tactical execution level, such as the tacit understanding of movement and the timing of pick-and-rolls in team cooperation, promoting the scientific transformation of basketball training from experience-driven to data-driven.
[0135] In terms of tactical simulation, traditional tactical boards and video reviews make it difficult for players to intuitively grasp the spatial relationships and timing in tactical execution. This application deeply integrates monitoring methods with the display function of a smart screen, enabling a closed-loop tactical simulation system that combines perception, analysis, and presentation. In training scenarios, the screen can dynamically draw heatmaps of running routes based on real-time collected player position information, overlaying and displaying the deviation between the ideal tactical path and the actual execution trajectory. This visual feedback helps players develop correct spatial awareness. In simulated combat, the system can identify players' intentions for sudden stops, turns, etc., based on pressure detection, and predict their next move based on distance changes. The screen display area then prompts defending players to position themselves in advance or attacking players to pass the ball in time. Furthermore, the long-term monitoring data accumulated by this method can construct a database of player athletic abilities, including multi-dimensional indicators such as maximum sprint speed, vertical jump height, change-of-direction agility, and sustained exercise endurance. Coaches can use these data models to conduct virtual simulations when developing tactics, assessing the feasibility of different lineup configurations and tactical approaches in actual execution, and even designing targeted tactics based on the characteristics of specific opponents' players.
[0136] In summary, this application redefines the intelligent training and competition model for basketball by leveraging multi-dimensional, high-precision, and real-time data acquisition capabilities.
[0137] An embodiment of the fourth aspect of this application proposes a computer-readable storage medium storing a processor-executable program. When executed by a processor, the processor-executable program is used to implement the monitoring method described above. The computer-readable storage medium provided by this application, by storing a processor-executable program, achieves software solidification and reusability of the aforementioned monitoring method. As the physical carrier of the program code, this storage medium ensures that the pressure detection algorithm, distance measurement algorithm, location positioning algorithm, and multi-dimensional information fusion output logic involved in the monitoring method can be stably saved and reliably read, providing a standardized software foundation for the deployment and implementation of the monitoring method on different hardware platforms. When the processor executes the program, it can precisely control the collaborative working timing of each functional module in the screen structure 10, ensuring that steps such as pressure detection, distance acquisition, and location tracking are completed simultaneously in the same first time, realizing synchronous acquisition and processing of multimodal data, and effectively avoiding data asynchrony problems caused by software execution timing errors.
[0138] This storage medium also endows the monitoring method with flexible adaptability and iterative upgrade capabilities. The editable nature of the program code allows the signal processing algorithms, threshold judgment logic, and information output formats in the monitoring method to be customized according to specific application scenarios, optimizing monitoring performance without changing the hardware structure. Simultaneously, as sensing technology and data analysis methods evolve, the system functions can be continuously upgraded by updating the program version in the storage medium, extending the technological lifecycle of the smart floor screen.

[0139] An embodiment of the fifth aspect of this application proposes a computer program product, including a computer program or computer instructions.

The computer program product provided by this application, by storing the computer program or computer instructions in a computer-readable storage medium and having them read and executed by the processor of a computer device, achieves complete software encapsulation and cross-platform deployment of the aforementioned monitoring method. This program product transforms the method steps of pressure detection, distance acquisition, position tracking, and synchronous output of multi-dimensional information into a sequence of instructions that can be recognized and executed by the processor. This makes the monitoring method no longer dependent on a specific hardware architecture, but can run stably on general-purpose or special-purpose computer devices with corresponding interfaces, improving the applicability and deployment flexibility of the technical solution. By executing this program product, the processor can accurately schedule the collaborative work of hardware modules such as the force sensing layer 500, infrared sensor 212, and light-emitting element 211 in the screen structure 10, ensuring that each functional step is completed within a strictly synchronized timing framework, achieving efficient acquisition, fusion processing, and real-time output of mechanical and optical signals.

As a software bridge connecting hardware functions and upper-level applications, this computer program product transforms the technological advantages of the aforementioned monitoring method into a deliverable, operable, and iterative standardized software solution, providing a technical path for the industrialization and ecosystem development of smart floor screens.
[0141] Below, refer to Figures 1 to 29 This application systematically describes the intelligent floor screen, monitoring method, and computer product according to a specific embodiment. This application achieves efficient integration of display, sensing, load-bearing, and buffering functions through a three-dimensional mechanical transmission architecture of seven horizontal layers and one vertical column. The screen structure 10, from top to bottom, consists of a force-bearing layer 100, a circuit board layer 200, a force transmission layer 300, a force sensing layer 500, and a base 600. The force-bearing layer 100 includes a mask structure and a force transmission structure 120. The circuit board layer 200 has through holes 230 for the force transmission structure 120 to pass through, forming a precise force transmission closed loop from the mask to the force sensing layer 500, thus suspending the circuit board layer 200 within a rigid frame to prevent impact damage.
[0142] Reference Figure 9 and 14 The mask structure of the force-bearing layer 100 divides the original single mask into multiple independent small units (4 screen structures 10 form a combination with a length L1 of 250mm, a width L2 of 250mm, and a thickness L3 of 26.4mm; each screen structure 10 has a length L4 of 125mm, a width L6 of 125mm, a single crystal block width L5 of 4.02mm, a distance L7 from the end of the force transmission structure 120 to the top of the force-bearing mask 110 of 21.6mm, and a thickness L8 of 5.5mm for the force-bearing mask 110; multiple screen structures 10 are connected horizontally to form an intelligent ground screen), which increases the number of pressure sensing channels and spatial accuracy to 4 times the original, enabling precise measurement of the foot pressure center and the force ratio of the forefoot / heel; the mask surface incorporates anti-slip texture (diamond-shaped protrusions with an included angle of 60°), keeping the coefficient of friction stable in the optimal range for athletes of 0.4-0.7, balancing anti-slip and smooth movement. The force transmission structure 120 array forms a miniature space frame system similar to an "I-beam," providing high-strength support in the vertical direction and a non-destructive clearance area for the circuit board layer 200 in the horizontal direction. The holes through which the supports pass through the circuit board layer 200 and the base shell have high precision (single-sided gap ≤ 0.1mm), allowing for stress release through slight deformation while strictly limiting unintended lateral displacement. The surface of the force-bearing shield 110 can be configured in various shapes, for example, as shown in the reference... Figure 23 The surface of the force-bearing mask 110 shown in the figure has a diamond-patterned texture, with its edges inclined at 45°, as referenced. Figures 23 to 25 The surface of the force-bearing mask 110 shown in the figure has a square grid pattern. Figure 24 In the process, the force transmission structure 120 has different lengths. The shorter force transmission structure 120 is used for threaded connection with the assembly base shell 220, while the longer one is used to realize the transmission of force.
[0143] The circuit board layer 200 includes a circuit board 210 and an assembly base 220, integrating 4096 LED beads (64×64 pixels) and 256 infrared sensors 212 (3519 pixels) arranged in a 16×16 pattern to determine the height of the athlete's feet based on the time of sound waves. The circuit board layer 200 is 0.2mm above the face mask and 0.5mm below the force transmission layer 300, spaced apart from the force-receiving layer 100 to avoid mechanical interference. The force transmission layer 300 has an installation position 310 and a detection position 320, with the installation position 310 surrounding the detection position 320. The detection position 320 has a detection block protruding towards the force-sensing layer 500. An elastic silicone layer is sandwiched between the force transmission layer 300 and the force-sensing layer 500, and its contact surface with the upper force-receiving support adopts a sawtooth or bump-shaped interlocking structure to increase the contact area, optimize force flow distribution, and reduce transmission loss. (Refer to...) Figures 26 to 28 The screen structure 10 of this application adopts a layered modular assembly design. The force-bearing layer 100, circuit board layer 200, and force transmission layer 300 can be pre-assembled to form independent functional modules. In one specific embodiment, a single module integrates four circuit board layers 200 and their corresponding force-bearing layers 100 and force transmission layers 300 to form a standardized 250mm×250mm unit. In some embodiments, the force sensing layer 500 can also be included in this module. The specific division method can be flexibly adjusted according to actual maintenance needs and site conditions. This modular architecture allows each functional layer to be quickly assembled and disassembled through the through-fitting of positioning protrusions 610 and positioning holes 510 and the adsorption connection of magnetic components 222. When a local unit fails, it can be removed and replaced separately from the horizontally spliced overall structure without disassembling adjacent modules or interrupting the overall system operation, thus improving the maintenance convenience and operational continuity of the smart stadium during long-term use.
[0144] The three-dimensional force transmission structure allows a single module to withstand instantaneous impacts of ≥500kg, with a theoretical service life of ≥100,000 hours, perfectly matching the intensity of professional sports. The force transmission path is significantly shortened and optimized, with a pressure sensing response time of ≤10ms and signal transmission stability improved by over 40%. For the ball, surface hardness ensures that the basketball's rebound trajectory meets professional standards; for the athlete, the cushioning system can absorb ≥55% of the impact force, and the absorption rate increases non-linearly with the impact, effectively protecting the athlete's joints; for the user experience, the surface flatness error is ≤0.3mm, eliminating any foreign object sensation, and the anti-slip texture provides optimal tactile feedback. The mounting base 220 is magnetically connected to the base 600 via magnetic components 222. The base 600 has positioning protrusions 610 that engage with the positioning holes 510 of the force sensing layer 500.
[0145] In summary, this application can accurately monitor the motion state of the target object, achieve precise transmission and high-speed response of pressure signals through a three-dimensional mechanical transmission structure, and simultaneously acquire the spatial position and vertical height information of the target object by combining infrared sensing technology. It constructs a multi-dimensional data monitoring system that includes mechanical characteristics, spatial coordinates and posture changes, providing high-precision and real-time data support for sports biomechanical analysis, technical movement correction, tactical execution evaluation and sports injury prevention, effectively improving the application value and reliability of smart floor screens in professional sports training and competitive matches.
[0146] In addition, the beneficial effects of this application include, but are not limited to, the following:
[0147] 1. Order-of-magnitude improvement in pressure sensing accuracy. This application employs a dot-matrix three-dimensional mechanical transmission architecture. Through the array arrangement of force transmission structures 120, the overall surface force of the traditional mask structure is transformed into a discrete point force mode. In a specific embodiment, 16×16=256 force transmission structures 120 are arranged within a single screen structure 10, forming 256 independent pressure sensing channels. Compared to the single force plane of the traditional 250mm×250mm mask structure, the spatial resolution of pressure sensing is increased to 256 times, achieving an order-of-magnitude leap in pressure sensing accuracy. This dot-matrix layout enables the system to accurately capture refined biomechanical parameters such as the pressure center trajectory of the athlete's foot and the forefoot / heel force ratio, providing high-precision data support for sports posture analysis and injury prevention.
[0148] 2. Simultaneous Expansion of Spatial Perception Dimensions and Accuracy. Circuit board layer 200 integrates 4096 light-emitting elements 211 arranged in a 64×64 array, and 256 infrared sensors 212 arranged in a 16×16 configuration. This integration density is approximately 256 times higher than traditional solutions, enabling a single screen structure 10 to achieve high-resolution visual output while simultaneously enabling non-contact detection of the vertical height and horizontal position of the target object. The infrared sensors 212 are used to emit and detect infrared radiation. This infrared radiation belongs to the near-infrared to far-infrared band of the electromagnetic spectrum (wavelength range approximately 0.75μm to 1mm), located between visible light and microwaves, and has a thermal effect (for example, the infrared radiation naturally emitted by the human body originates from this characteristic). By using infrared sensors 212 to detect the distance between the athlete's foot and the pressure layer 100 in real time, and fusing pressure detection data, a multi-dimensional data monitoring system covering mechanical characteristics, spatial coordinates, and posture change information is constructed, with an information density approximately 10,000 times higher than a single sensing mode.
[0149] 3. Deep decoupling of mechanical and optoelectronic functions. This application utilizes a three-dimensional transmission design where the force transmission structure 120 passes through the via 230 of the circuit board layer 200, completely separating the LED display function, infrared sensing function, and pressure detection function in physical space. The light-emitting element 211 and the infrared sensor 212 are encapsulated within the first cavity defined by the mounting base 220 and are protected circumferentially by the side wall 221; the force transmission structure 120 forms an independent rigid force transmission channel, directly transmitting external impacts to the force sensing layer 500. This architecture eliminates physical interference and signal crosstalk between the display module, sensing module, and load-bearing structure in traditional planar stacked layouts, avoids the risk of failure of LED devices and infrared elements due to mechanical stress, and ensures the independent and stable operation of each functional module under complex mechanical environments.
[0150] 4. Modular design significantly improves maintenance efficiency. The screen structure 10 of this application adopts a layered plug-in assembly design, enabling rapid disassembly and assembly for front maintenance. The circuit board layer 200 is magnetically connected to the base 600 via magnetic components 222 on the mounting base 220. A single 250mm×250mm unit can be directly removed and replaced from above using a vacuum suction cup. The base 600 uses 500mm×1000mm standard units, and horizontal splicing is achieved through the interlocking of positioning protrusions 610 and positioning holes 510 on the force sensing layer 500, supporting pull-out disassembly from the front of the court. This modular architecture allows a standard 460-square-meter basketball court to be assembled from 1840 circuit board layer units and 920 base units. Any unit can be replaced independently in case of failure without interrupting the overall system operation, reducing maintenance response time from several hours to minutes.
[0151] 5. Enhanced structural reliability under dynamic loads. The three-dimensional mechanical transmission architecture allows a single module to withstand instantaneous impacts of ≥500kg, with a theoretical service life of ≥100,000 hours, perfectly matching the intensity of professional sports. An elastic buffer layer 400, sandwiched between the force transmission layer 300 and the force sensing layer 500, can absorb ≥55% of the impact force, with the absorption rate increasing non-linearly with increasing impact, effectively protecting the athlete's knee, ankle, and plantar fascia. Surface flatness error ≤0.3mm, combined with an anti-slip texture with a friction coefficient of 0.4~0.7, ensures the basketball's rebound trajectory meets professional standards while providing optimal sports feel and joint protection.
[0152] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
