Description

Technical Field

[0001] This invention relates to the field of building wall panels, and more particularly to a seamless splicing wall panel installation system. Background Technology

[0002] Wall panels are decorative panels applied to wall surfaces. Seamless wall panels are aesthetically pleasing and offer a strong sense of unity, adaptable to curved and arched shapes, and convenient for prefabricated construction, making them increasingly mainstream. The splicing quality of seamless wall panels depends on the uniformity of the gap width and the control of misalignment between adjacent panels. Current installation methods largely rely on worker experience or fixed machinery performing the installation process, requiring multiple adjustments after measurement with measuring tools to ensure installation quality, resulting in low efficiency. Some solutions collect images of the panel seams to calculate errors and drive adjustment mechanisms for correction; however, in some building interior construction environments, the image acquisition process is easily affected by lighting and site obstructions, leading to poor efficiency.

[0003] Chinese Patent Publication No. CN110894747A, belonging to the field of integrated wall panel technology, proposes a wall panel installation component, including a keel frame with a hole, a first bolt with a nut at one end and the other end passing through the hole, a clip that is engaged with the keel frame to hold the nut, a fixing bolt with a threaded hole for screwing in, a slot and an insert for insertion into the slot, one of which is located on the keel frame and the other on the panel. The invention also proposes an integrated wall panel installation system, including a wall panel installation component, a panel with a dovetail groove, and a slider located in the dovetail groove and connected to the wall panel installation component. This technical solution solves the problems of existing integrated wall panels, such as difficulty in controlling and adjusting flatness, difficulty in disassembly and repair after installation, thick installation reducing indoor space, easy expansion and contraction in summer and winter leading to gaps, and the need for adhesive, which is environmentally unfriendly and has poor performance.

[0004] However, the following problems still exist in the existing technology: 1. In the existing technology, the joint error is not considered to be formed by two adjacent panels. Only the magnitude of the error is measured without distinguishing which panel the error originates from. The determination of the adjustment object lacks a basis, and the error is easy to be transmitted and accumulated along the wall surface. 2. In the existing technology, the measurement process is easily affected by the surface condition of the panel and the on-site environment. The measurement results under complex environments cannot provide a reliable basis for installation and adjustment. Summary of the Invention

[0005] To address this issue, the present invention provides a seamless splicing wall panel installation system to overcome the problems in the prior art where inaccurate splicing measurement and unclear error sources lead to inaccurate adjustments and difficulty in guaranteeing installation quality in seamless splicing wall panel installation scenarios.

[0006] To achieve the above objectives, the present invention provides a seamless splicing wall panel installation system, comprising: The time-sharing lighting module is used to control the controllable light source to light up at different times, so as to project the corresponding transmitted light pattern through the splicing gap between the two wall panels to be spliced. The pattern recognition module is used to collect each of the transmitted light patterns and identify the characteristic parameters of the transmitted bright band in the transmitted light pattern; An error calculation module is used to calculate splicing error parameters based on the characteristic parameters in order to determine whether the splicing state of the splicing gap meets the preset installation accuracy conditions. The micro-motion excitation module is used to control the installation adjustment mechanism corresponding to the two wall panels to be spliced ​​to perform trial adjustment micro-motion in response to the splicing state not meeting the installation accuracy conditions. An error component determination module is used to obtain the adjustment amount of the trial adjustment micro-motion and the change amount of the splicing error parameter before and after the trial adjustment micro-motion, so as to determine the error component of the splicing error parameter between the two wall panels to be spliced. The correction amount allocation module is used to determine the target correction amount of each of the two wall panels to be spliced ​​according to the error component, and to determine the adjustment command of each spliced ​​wall panel according to the target correction amount.

[0007] Furthermore, the process by which the time-sharing lighting module controls the controllable light source to illuminate at different times, so as to project a corresponding transmitted light pattern through the splicing gap between the two wall panels to be spliced, includes: In response to the target panel being hung in place among the two wall panels to be spliced, the controllable light source is controlled to light up at different incident angles in a time-sharing manner to illuminate the splicing gap and project the corresponding transmitted light pattern. Record the lighting sequence and incident angle for each lighting cycle; The controllable light source is located behind the splicing side of the two wall panels to be spliced.

[0008] Furthermore, the process by which the pattern recognition module acquires each of the transmitted light patterns and identifies the characteristic parameters of the transmitted bright bands in the transmitted light patterns includes: In response to each lighting cycle, the corresponding transmitted light pattern is acquired, and the light intensity distribution of the transmitted light pattern is determined. The multiple light intensity distributions collected along the extension direction of the splicing seam are arranged in the collection order to generate a corresponding grayscale image; Image segmentation is performed on the grayscale image to identify the transmission bright bands, thereby extracting the feature parameters of the transmission bright bands; The characteristic parameters include the bandwidth parameter and the band edge parameter of the transmitted bright band.

[0009] Furthermore, the error calculation module includes: The difference determination submodule is used to determine the amount of difference in the feature parameters between each lighting cycle; An error calculation submodule is used to determine splicing error parameters based on the difference amount; The accuracy determination submodule is used to determine whether the splicing state of the splicing gap meets the installation accuracy conditions based on the splicing error parameters. The splicing error parameters include the gap width and the misalignment.

[0010] Furthermore, the process by which the accuracy determination submodule determines whether the splicing state of the splicing gap meets the installation accuracy conditions based on the splicing error parameters includes: Based on the corresponding accuracy threshold and the splicing error parameters, an accuracy condition determination is performed. If either the gap width or the misalignment is greater than the corresponding accuracy threshold, then the splicing state is determined not to meet the installation accuracy conditions.

[0011] Furthermore, the process by which the error calculation submodule calculates the splicing error parameters based on the difference includes: The gap width is determined based on the difference in the width of the transmitted bright band between each illumination. The misalignment amount is determined based on the difference in the slope of the two sides of the transmitted bright band between each illumination.

[0012] Furthermore, the micro-motion excitation module, in response to the splicing state not meeting the installation accuracy conditions, controls the installation adjustment mechanisms corresponding to the two wall panels to be spliced ​​to perform a trial adjustment micro-motion process, including: Based on the splicing error parameters, the adjustment amount of the tentative adjustment micro-motion is determined; The corresponding installation adjustment mechanism is controlled to perform trial adjustment micro-motion according to the adjustment amount.

[0013] Furthermore, the process by which the error component determination module acquires the adjustment amount of the trial adjustment micro-motion and the change in the splicing error parameter before and after the trial adjustment micro-motion, in order to determine the error component of the splicing error parameter between the two wall panels to be spliced, includes: Obtain the pre-micro-motion splicing error parameters calculated before the trial adjustment micro-motion is executed and the post-micro-motion splicing error parameters calculated after the execution; The change in the splicing error parameter is determined based on the difference between the splicing error parameter before and after the micro-motion. The error component is determined based on the correspondence between the change and the adjustment.

[0014] Further, the correction amount allocation module allocates the correction amount corresponding to the splicing error parameter to the two wall panels to be spliced ​​according to the error component and the adjustment constraint parameters of each splicing wall panel, and the process of determining the adjustment command of each splicing wall panel includes: The installation process data of the two wall panels to be spliced ​​are obtained to determine the adjustment constraint parameters of each spliced ​​wall panel; Based on the error components, determine the initial correction amount for each of the two wall panels to be spliced. Each of the initial correction amounts is corrected according to the adjustment constraint parameters to determine each of the target correction amounts; Based on the target correction amount, determine the adjustment command for each of the splicing wall panels; The adjustment constraint parameters include the number of locked points of the splicing wall panel, the remaining adjustment stroke of the installation adjustment mechanism, and the adjustment transmission coefficient of the splicing wall panel.

[0015] Furthermore, the process by which the correction amount allocation module determines the adjustment command for each of the splicing wall panels based on each of the target correction amounts includes: Identify the installed wall panel among the two wall panels to be spliced; If the remaining adjustment stroke of the installation adjustment mechanism corresponding to the installed splicing wall panel is greater than the target correction amount corresponding to the installed splicing wall panel, then compare the number of locking points of the installed splicing wall panel with that of another wall panel to be spliced. If the number of locking points of the installed splicing wall panel is small, then based on the target correction amount corresponding to the installed splicing wall panel, a callback adjustment instruction is executed on the installation adjustment mechanism corresponding to the installed splicing wall panel, and this instruction is determined as the adjustment instruction.

[0016] Compared with existing technologies, this invention controls a controllable light source to illuminate in a time-sharing manner through a time-sharing lighting module. A transmitted light pattern is projected through the splicing seams. A pattern recognition module identifies the characteristic parameters of the transmitted light bands, an error calculation module calculates the splicing error parameters to determine whether the splicing state meets the installation accuracy requirements, a micro-motion excitation module controls the installation adjustment mechanism to perform tentative micro-motion adjustments, an error component determination module determines the error components of the two wall panels to be spliced ​​based on the change in splicing error parameters before and after the micro-motion, and a correction amount allocation module determines the target correction amount and adjustment command accordingly. This invention avoids the gradual accumulation of errors along the wall panel installation process, improving installation accuracy and efficiency.

[0017] In particular, this invention addresses the problem of blind adjustments due to unclear sources of splicing seam errors. In actual installation, the error in the splicing seam is formed by the combined effect of two adjacent panels. The hanging deviation of the already installed panels and the posture deviation of the current panel are superimposed on the same seam. Measuring only the magnitude of the error cannot determine which panel is primarily responsible, and the installation error may accumulate and propagate along the wall panel installation process. When the splicing state does not meet the installation accuracy requirements, the micro-motion excitation module of this invention controls the installation adjustment mechanism to perform a known trial adjustment micro-motion. The error component determination module determines the error component of the splicing error parameter between the two wall panels to be spliced ​​based on this adjustment amount and the change in splicing error parameters before and after the micro-motion. The correction amount allocation module determines the target correction amount for each of the two wall panels to be spliced ​​according to the error component and generates adjustment instructions. Therefore, the larger the error component attributable to a particular panel, the more correction amount that panel bears, avoiding error propagation and repeated disassembly and reassembly caused by misadjusting the current panel, ensuring the consistency of the overall wall splicing accuracy, and improving installation quality.

[0018] In particular, addressing the issue of seam measurement being easily affected by environmental interference in construction site scenarios, the time-sharing lighting module controls the controllable light source to illuminate at different times, projecting transmitted light patterns through the seams. The pattern recognition module collects the transmitted light patterns and identifies the characteristic parameters of the transmitted light bands. The measurement process is less affected by panel surface texture, reflections, and obstruction by installers, and can still stably provide a reliable data foundation for subsequent adjustments even in construction sites with varying dust and lighting conditions.

[0019] In particular, this invention further provides the basis for determining the callback of installed panels. In construction sites, the main source of splicing errors is sometimes the already locked panels. However, the conventional practice is to only adjust the current panel and avoid touching the installed panels, leading to excessive adjustments of the current panel to accommodate errors, which in turn introduces new deviations. The correction amount allocation module of this invention determines to execute a callback adjustment command on the installed splicing wall panel when the remaining adjustment stroke of the installed splicing wall panel meets the target correction amount and the number of locked points is small. This removes the limitation of only adjusting the current panel, allowing the panel with the larger error component and lower adjustment cost to bear the correction amount, reducing error accumulation and rework.

This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0024] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Please see Figure 1 As shown, this is a structural schematic diagram of the seamless splicing wall panel installation system according to an embodiment of the present invention. The system of this embodiment includes: The time-sharing lighting module is used to control the controllable light source to light up at different times, so as to project the corresponding transmitted light pattern through the splicing gap between the two wall panels to be spliced. The pattern recognition module is used to collect each of the transmitted light patterns and identify the characteristic parameters of the transmitted bright band in the transmitted light pattern; An error calculation module is used to calculate splicing error parameters based on the characteristic parameters in order to determine whether the splicing state of the splicing gap meets the preset installation accuracy conditions. The micro-motion excitation module is used to control the installation adjustment mechanism corresponding to the two wall panels to be spliced ​​to perform trial adjustment micro-motion in response to the splicing state not meeting the installation accuracy conditions. An error component determination module is used to obtain the adjustment amount of the trial adjustment micro-motion and the change in the splicing error parameter before and after the trial adjustment micro-motion, so as to determine the error component of the splicing error parameter between the two wall panels to be spliced. The correction amount allocation module is used to determine the target correction amount of each of the two wall panels to be spliced ​​according to the error component, and to determine the adjustment command of each spliced ​​wall panel according to the target correction amount.

[0026] Specifically, this invention uses a time-sharing lighting module to control the illumination of a controllable light source at different times, projecting corresponding transmitted light patterns through the splicing gap between two wall panels to be spliced. A pattern recognition module collects each transmitted light pattern and identifies the characteristic parameters of the transmitted bright bands. An error calculation module calculates the splicing error parameters based on the characteristic parameters to determine whether the splicing state of the splicing gap meets the preset installation accuracy conditions. When the splicing state does not meet the installation accuracy conditions, a micro-motion excitation module controls the installation adjustment mechanism to perform a trial adjustment micro-motion. An error component determination module determines the error component of the splicing error parameters between the two wall panels based on the adjustment amount of the trial micro-motion and the change in the splicing error parameters before and after the micro-motion. A correction amount allocation module determines the target correction amount for each of the two wall panels based on the error component and determines the adjustment command for each splicing wall panel based on each target correction amount. After each installation adjustment mechanism completes the adjustment according to the adjustment command, the error calculation module recalculates the splicing error parameters until the splicing state meets the installation accuracy conditions, eliminating the need for repeated trial adjustments based on worker experience.

[0027] Specifically, the installation accuracy condition is a preset criterion used to determine whether the installation error of the splicing gap meets the installation requirements; the installation accuracy condition is configured based on the acceptance requirements of the wall decoration project, and the stricter the installation accuracy condition, the more splicing gaps will be judged as not meeting the installation accuracy condition.

[0028] Specifically, exploratory fine-tuning refers to small-amplitude adjustments with known adjustment amounts, used to elicit identifiable changes in splicing error parameters, rather than to directly eliminate errors in splicing gaps.

[0029] It is understood that the seamless splicing wall panel installation system proposed in this invention is mainly applied to wall panel splicing installation scenarios in the field of architectural decoration, such as on-site installation of flat walls, curved walls, and curved-shaped walls in public buildings such as commercial complexes, airports, train stations, and exhibition halls. It is especially suitable for seamless splicing wall panel installation projects with high requirements for the appearance of the splices and the flatness of the surface. The technical concept of this invention can also be extended to other assembly fields with similar needs for measuring splicing errors and distinguishing the sources of errors, including stone and tile laying, metal curtain wall panel installation, prefabricated interior partition wall panel assembly, flooring and ceiling panel laying, etc., where it is necessary to control the gap width and misalignment, which will not be elaborated here.

[0030] It should be noted that the multiple functional modules involved in this application are only logical divisions based on the functions implemented according to the present invention. The specific physical structures of the time-sharing lighting module, pattern recognition module, error calculation module, micro-motion excitation module, error component determination module, and correction amount allocation module are not limited. They can be composed of logic components, including field-programmable gate arrays, application-specific integrated circuits, computers, or microprocessors in computers, which will not be elaborated here.

[0031] Specifically, the controllable light source and the acquisition device for the transmitted light pattern are respectively located on both sides of the splicing gap. The controllable light source is positioned behind the splicing side of the two wall panels to be spliced, and the acquisition device is positioned on the imaging side of the transmitted light pattern. Both are communicatively connected to the time-sharing illumination module and the pattern recognition module. The error calculation module, the micro-motion excitation module, the error component determination module, and the correction amount allocation module are deployed on the field control terminal. The field control terminal is communicatively connected to the acquisition device to acquire and analyze the transmitted light pattern. The micro-motion excitation module and the correction amount allocation module are communicatively connected to the installation adjustment mechanism on the back of each splicing wall panel to issue exploratory adjustment micro-motion and adjustment commands.

[0032] Specifically, the seamless splicing wall panel installation system in this embodiment is used to install a seamless wall panel with overlapping flanges: one side of the seamless wall panel has an outwardly extending flange; when two adjacent wall panels are spliced, the flange of one wall panel overlaps the flange of the other wall panel, and the splicing gap is covered by the overlapping flange from the decorative surface of the wall panel, so that the decorative surface presents a seamless effect; a gap channel for light to pass through is maintained between the flanges of the two wall panels, and the light projected by the controllable light source from the rear of the splicing side passes through the gap channel to form the transmitted light pattern; a hook is provided on the back of the seamless wall panel to facilitate connection with the installation adjustment mechanism; the installation adjustment mechanism is used to adjust the installation position of the wall panel.

[0033] Specifically, the process by which the time-sharing lighting module controls the controllable light source to illuminate in a time-sharing manner, so as to project a corresponding transmitted light pattern through the splicing gap between the two wall panels to be spliced, includes: In response to the target panel being hung in place among the two wall panels to be spliced, the controllable light source is controlled to light up at different incident angles in a time-sharing manner to illuminate the splicing gap and project the corresponding transmitted light pattern. Record the lighting sequence and incident angle for each lighting cycle; The controllable light source is located behind the splicing side of the two wall panels to be spliced.

[0034] Specifically, the controllable light source is a lighting device with controllable lighting timing and lighting parameters, used to light up at different incident angles under the control of the time-sharing lighting module.

[0035] Please see Figure 2 As shown, this is a schematic diagram of the transmitted light pattern and characteristic parameters in an embodiment of the present invention. In this embodiment, the controllable light source is a linear light-emitting unit group located behind the splicing side of the two wall panels to be spliced. The linear light-emitting unit group is arranged along the extension direction of the splicing gap and includes multiple light-emitting units with different incident angles. The time-sharing lighting module illuminates each light-emitting unit sequentially according to a preset lighting sequence, so that each lighting corresponds to a different incident angle. The lighting duration and brightness of each light-emitting unit are adjustable to adapt to different panel materials and ambient light conditions.

[0036] It is understandable that a controllable light source can also use a single light-emitting unit in conjunction with a tilting mechanism or light guide component to change the incident angle, so as to form illumination with different incident angles at different times, which will not be elaborated further.

[0037] It is understood that the present invention establishes a one-to-one correspondence between each lighting and each transmitted light pattern by recording the lighting sequence and the incident angle of each lighting, so that the characteristic parameters of each lighting can be compared according to the corresponding incident angle.

[0038] Specifically, the transmitted light pattern is an optical pattern formed by light from a controllable light source passing through the splicing gaps, which can be acquired by the acquisition device.

[0039] In this embodiment, the light from the controllable light source passes through the gap between the flanges of the two wall panels to be spliced, forming a transmitted light pattern on the photosensitive surface of the acquisition device. The transmitted light pattern shows a transmitted bright band distributed along the extension direction of the splicing gap. The width of the transmitted bright band is related to the width of the splicing gap, and the rate of change of light intensity along both sides of the transmitted bright band is related to the misalignment of the splicing gap. Based on this, the pattern recognition module identifies the characteristic parameters of the transmitted bright band from the transmitted light pattern.

[0040] Specifically, the pattern recognition module includes: The light intensity determination submodule is used to collect the corresponding transmitted light pattern in response to each lighting, so as to determine the light intensity distribution of each transmitted light pattern, including the light intensity values ​​of each collection position distributed along the extension direction of the splicing seam. The bright band recognition submodule is used to perform image segmentation on grayscale images to identify transmitted bright bands and extract the feature parameters of the transmitted bright bands; The grayscale image is generated by arranging multiple light intensity distributions in the order of acquisition.

[0041] Specifically, the process by which the pattern recognition module acquires each of the transmitted light patterns and identifies the characteristic parameters of the transmitted bright bands in the transmitted light patterns includes: In response to each lighting cycle, the corresponding transmitted light pattern is acquired, and the light intensity distribution of the transmitted light pattern is determined. The multiple light intensity distributions collected along the extension direction of the splicing seam are arranged in the collection order to generate a corresponding grayscale image; Image segmentation is performed on the grayscale image to identify the transmitted bright band. Continuous intervals in the light intensity distribution of the transmitted bright band with light intensity values ​​greater than a preset intensity threshold are extracted to determine the bandwidth parameter. The light intensity change rate on both sides of the transmitted bright band is extracted to determine the band edge parameter. The characteristic parameters include the bandwidth parameter and the band edge parameter of the transmitted bright band.

[0042] In this embodiment, the preset intensity threshold is determined based on the peak intensity of the light intensity distribution.

[0043] In this embodiment, the specific value of the preset intensity threshold is determined based on the ambient light and the differences in panel material, which will not be elaborated here.

[0044] Specifically, the error calculation module includes: The difference determination submodule is used to determine the amount of difference of the feature parameters between each lighting, the amount of difference including the amount of difference of the bandwidth parameter between each lighting and the amount of difference of the band edge parameter between each lighting. An error calculation submodule is used to determine splicing error parameters based on the difference amount, so as to determine the installation error state of the splicing gap; The accuracy determination submodule is used to determine whether the splicing state of the splicing gap meets the installation accuracy conditions based on the splicing error parameters. The splicing error parameters include the gap width and the misalignment.

[0045] The splicing error parameters include the misalignment amount determined based on the distance between the edges of the two wall panels to be spliced ​​at the splicing seam and the height difference between the decorative surfaces of the two wall panels to be spliced ​​at the splicing seam.

[0046] It is understandable that the misalignment is the height difference between the decorative surfaces of two wall panels to be spliced ​​at the splicing seam, and its value depends on which of the two wall panels protrudes from the other.

[0047] Please see Figure 3 As shown, it is a logic judgment diagram for determining whether the splicing state meets the installation accuracy conditions in an embodiment of the present invention.

[0048] Specifically, the process by which the accuracy determination submodule determines whether the splicing state of the splicing gap meets the installation accuracy conditions based on the splicing error parameters includes: Based on the corresponding accuracy threshold and the splicing error parameters, an accuracy condition determination is performed. If either the gap width or the misalignment is greater than the corresponding accuracy threshold, then the splicing state is determined not to meet the installation accuracy conditions.

[0049] In this embodiment, the error calculation module further includes a precision threshold determination submodule, which is used to determine the precision threshold corresponding to the gap width and the misalignment amount based on the acceptance requirements of the wall decoration project, the panel specifications of the two wall panels to be spliced, and the on-site construction conditions.

[0050] Understandably, higher acceptance requirements place greater emphasis on the appearance of the joints and the flatness of the surface. Even minute gaps and misalignments can affect the acceptance results. In such cases, a smaller precision threshold is needed to classify these minor errors as failures to meet installation accuracy requirements, triggering subsequent exploratory adjustments. Conversely, lower acceptance requirements allow for larger precision thresholds that minimize the impact on the decorative effect, avoiding unnecessary repeated adjustments. Therefore, the stricter the acceptance requirements, the smaller the precision threshold should be. Those skilled in the art can adjust the precision threshold according to the actual acceptance requirements, which will not be elaborated further here.

[0051] Specifically, the process by which the error calculation submodule calculates the splicing error parameters based on the difference includes: The gap width is determined based on the difference in the width of the transmitted bright band between each illumination. The misalignment amount is determined based on the difference in the slope of the two sides of the transmitted bright band between each illumination.

[0052] Understandably, as the incident angle changes, the degree to which the edge of the board forming the splicing gap blocks light also changes. When the edge of the board on the misaligned side protrudes, that side edge blocks light at different incident angles to varying degrees. The slope of the two sides of the transmitted bright band changes differently between each illumination, and the width of the transmitted bright band is mainly affected by the cross-sectional area of ​​the gap channel. Based on this, the error calculation submodule maps the difference in the width direction and the difference in the two sides to the gap width and misalignment respectively, achieving single-time decoupling of the two types of errors.

[0053] Specifically, the installation adjustment mechanism is an adjustment component located on the back of the splicing wall panel, used to adjust the installation position of the splicing wall panel to adjust the gap width and the misalignment. Specifically, the tentative adjustment micro-motion is a small adjustment action with a known adjustment amount, which is less than the correction amount corresponding to the splicing error parameter. It is used to stimulate a identifiable change in the splicing error parameter, rather than to eliminate the error of the splicing gap, so as to avoid over-adjustment that introduces new errors.

[0054] In this embodiment, the installation adjustment mechanism includes multiple electrically adjustable rods distributed on the back of the splicing wall panel. The extension amount of each electrically adjustable rod is independently adjustable: when each electrically adjustable rod extends by the same amount, the overall installation position of the splicing wall panel changes; when each electrically adjustable rod extends by different amounts, the surface curvature of the splicing wall panel changes; each electrically adjustable rod has a built-in displacement sensor for feedback of the actual extension amount, which serves as the actual execution amount of the installation adjustment mechanism.

[0055] In this embodiment, the adjustment amount is determined based on the splicing error parameter and the minimum identifiable change of the feature parameter by the pattern recognition module. In practice, the specific size of the adjustment amount should be determined according to the equipment performance of the pattern recognition module, which will not be elaborated here.

[0056] It is understandable that if the adjustment amount is too large, the splicing state may deviate further from the installation accuracy conditions, while if the adjustment amount is too small, the change in the feature parameters will be difficult for the pattern recognition module to recognize.

[0057] Please see Figure 4 The diagram shown illustrates the logic for determining the error component and target correction amount in an embodiment of the present invention. Specifically, the error component determination module acquires the adjustment amount of the trial adjustment micro-motion and the change in the splicing error parameter before and after the trial adjustment micro-motion, in order to determine the error component of the splicing error parameter between the two wall panels to be spliced. This process includes: Obtain the pre-micro-motion splicing error parameters calculated before the trial adjustment micro-motion is executed and the post-micro-motion splicing error parameters calculated after the execution; The change in the splicing error parameter is determined based on the difference between the splicing error parameter before and after the micro-motion. Based on the correspondence between the change and the adjustment, the error components in the splicing error parameters belonging to each of the wall panels to be spliced ​​are determined. The error component is determined based on the ratio of the change to the adjustment. The larger the ratio, the larger the error component corresponding to the wall panel to be spliced ​​that has undergone the tentative adjustment.

[0058] In this embodiment, when the two wall panels to be spliced ​​are subjected to the trial adjustment micro-motion one after the other, the ratio of the ratio corresponding to the two trial adjustment micro-motions is equal to the ratio of the error components of the two wall panels to be spliced, and the sum of the error components of the two wall panels to be spliced ​​is equal to the splicing error parameter. Based on this, the error component corresponding to each wall panel to be spliced ​​is calculated.

[0059] Specifically, the correction amount allocation module allocates the correction amount corresponding to the splicing error parameter to the two wall panels to be spliced ​​based on the error component and the adjustment constraint parameters of each splicing wall panel. The process of determining the adjustment command for each splicing wall panel includes: The installation process data of the two wall panels to be spliced ​​are obtained to determine the adjustment constraint parameters of each spliced ​​wall panel, so as to determine the difficulty and scope of influence of adjusting each spliced ​​wall panel; Based on the error components, determine the correction direction and correction value corresponding to each of the spliced ​​wall panels, so as to determine the initial correction amount of each of the two wall panels to be spliced. Each of the initial correction amounts is corrected according to the adjustment constraint parameters to determine each of the target correction amounts; Based on the target correction amount, determine the adjustment command for each of the splicing wall panels; The adjustment constraint parameters include the number of locked points of the splicing wall panel, the remaining adjustment stroke of the installation adjustment mechanism, and the adjustment transmission coefficient of the splicing wall panel.

[0060] In this embodiment, a corresponding locking record is generated after each locking operation at a locking point is completed during the installation process.

[0061] It is understood that the number of locked points is determined based on the locking record. The more locked points there are, the more fixed the relative position of the spliced ​​wall panel and the keel is, the more locking points need to be released when making adjustments, and the greater the difficulty of adjustment.

[0062] In this embodiment, the installation and adjustment mechanism has a built-in displacement sensor. The displacement sensor provides real-time feedback on the adjustment position as the installation and adjustment mechanism adjusts, thereby determining the stroke feedback. The remaining adjustment stroke is determined based on the stroke feedback and the total stroke of the installation and adjustment mechanism.

[0063] In this embodiment, the adjustment transfer coefficient is determined based on the adjustment amount of the trial adjustment micro-motion and the change in the splicing error parameter. The adjustment amount and the change are measured during the execution of the trial adjustment micro-motion. The larger the adjustment transfer coefficient, the greater the change in the splicing error parameter caused by the adjustment of the splicing wall panel, and the larger the range of influence of the adjustment.

[0064] Specifically, the process by which the correction amount allocation module determines the adjustment command for each of the splicing wall panels based on each of the target correction amounts includes: Identify the installed wall panel among the two wall panels to be spliced; If the remaining adjustment stroke of the installation adjustment mechanism corresponding to the installed splicing wall panel is greater than the target correction amount corresponding to the installed splicing wall panel, then compare the number of locking points of the installed splicing wall panel with that of another wall panel to be spliced. If the number of locking points of the installed splicing wall panel is small, then based on the target correction amount corresponding to the installed splicing wall panel, a callback adjustment instruction is executed on the installation adjustment mechanism corresponding to the installed splicing wall panel, and this instruction is determined as the adjustment instruction.

[0065] In this embodiment, if the remaining adjustment stroke is insufficient to execute the target correction amount, the portion exceeding the remaining adjustment stroke is determined to be included in the target correction amount of another wall panel to be spliced.
