[0002] The inner formwork of a precast beam is a commonly used formwork in construction projects, and is mainly used in the manufacturing process of precast beams. The formwork is mainly assembled from small pieces of shaped steel formwork. These small pieces of steel formwork usually use wedge-shaped joints when assembled to facilitate the disassembly of the formwork. In order to avoid obvious deformation of the inner formwork, a channel steel frame will be installed on the inside to enhance its stability. During the manufacturing process of the inner formwork of a precast beam, the design requirements of the beam will be determined first, and then the specifications and structure of the formwork will be determined based on these requirements. Next, a formwork with a specific shape, size and structure is manufactured using a steel formwork, and then concrete is poured into it to produce a precast concrete beam that meets the design requirements. During the assembly process of the inner formwork of the precast beam, it is necessary to analyze the assembly effect. At this time, a monitoring system for the assembly process of the hinge of the inner formwork of the precast beam is required;

[0003] When monitoring the assembly process of the inner mold hinge of the prefabricated beam, the prior art usually analyzes the image and assembly strength of the assembly parts after the assembly is completed to analyze whether the assembly requirements are met. However, this method has serious lag. The prior art cannot comprehensively analyze the deformation of the inner mold hinge and the abnormal conditions of the assembly process to predict and analyze the assembly results, resulting in reduced safety and efficiency in the assembly process. Most of the prior art has the above problems.

[0004] In order to solve the problems raised by the background technology, the present application designs a precast beam inner mold hinge assembly process monitoring system and method based on data analysis. Summary of the invention

[0040] To solve the technical problem raised in the background technology: when monitoring the assembly process of the inner mold hinge of the prefabricated beam, the prior art usually analyzes the image and assembly strength of the assembly parts after the assembly is completed to analyze whether the assembly requirements are met. However, this method has serious hysteresis. The prior art cannot comprehensively analyze the deformation of the inner mold hinge and the abnormal conditions of the assembly process to predict and analyze the assembly results, resulting in reduced safety and efficiency of the assembly process. The present invention provides a preferred embodiment: Figure 1-Figure 3 As shown, the method for monitoring the assembly process of the inner mold hinge of the precast beam based on data analysis includes the following specific steps:

[0041] S1, obtaining image data of the hinge connection of the inner mold of the precast beam at the beginning of assembly, and obtaining vibration data and deformation data of the connection position during the assembly process;

[0042] In a specific embodiment, the image data of the connection of the inner mold hinge of the precast beam at the beginning of assembly is obtained, and the specific contents of obtaining the vibration data and deformation data of the connection position during the assembly process are:

[0043] S11, acquiring three-dimensional image data of two corresponding inner mold hinge connections at the start of assembly, and storing the data in a first storage component;

[0044] The following methods can be used to obtain the three-dimensional image data of the inner mold hinge joint: 3D scanning technology: Use a professional 3D scanner to scan the hinge joint. This device can capture the geometric shape of the object surface and generate high-precision 3D point cloud data. Through software processing, the point cloud data can be converted into a 3D model to obtain a detailed 3D image of the hinge joint; Photogrammetry technology: Use multiple cameras to shoot the hinge joint from different angles, and use photogrammetry software to process the photos to generate a 3D model. This method requires precise camera calibration and photo matching to ensure that the generated 3D model has sufficient accuracy;

[0045] S12, respectively obtaining the vibration amplitude and vibration frequency data of the connection between the two inner mold hinges during the assembly process, and simultaneously obtaining the pressure data of each point corresponding to the connection seam during the assembly process and the deformation data of the connection between the two inner mold hinges, wherein the deformation data includes the image data of the wear position during the assembly process, which is stored in the second storage component; it should be noted that the image data of the wear position here includes the wear position volume and wear corresponding position data, and simultaneously the vibration amplitude and vibration frequency data of the connection between the inner mold hinges here are directly obtained by a displacement sensor or a vibration sensor installed at the connection between the inner mold hinges, and the use of the displacement sensor or the vibration sensor is a conventional technical means in the art, which will not be described in detail herein;

[0046] S2, obtaining the image data of the hinge connection of the inner mold of the precast beam at the beginning of the corresponding assembly and importing it into the assembly deformation abnormality analysis model to perform assembly deformation abnormality analysis;

[0047] In a specific embodiment, obtaining the image data of the hinge connection of the inner mold of the prefabricated beam at the beginning of the assembly and importing it into the assembly deformation abnormality analysis model for assembly deformation abnormality analysis includes the following specific steps:

[0048] S21, obtaining three-dimensional image data of two corresponding inner mold hinge connections at the start time of assembly, and comparing them with the designed three-dimensional image of the inner mold hinge connection, obtaining corresponding areas where the three-dimensional image of the inner mold hinge connection is different from the designed three-dimensional image, obtaining several assembly deformation areas, and obtaining the shapes, positions and volumes of all assembly deformation abnormal areas;

[0049] S22, obtaining position data of the corresponding assembly deformation area after the design three-dimensional image is assembled on the simulation software, taking the center position of one of the assembly deformation areas as the selection point, it should be noted that the center position here is the point with the largest depth of the assembly deformation area, obtaining the sum of the shortest distances from the selection point to the other corresponding assembly deformation areas, obtaining the minimum shortest distance and the corresponding assembly deformation area as the center deformation area;

[0050] S23, obtaining the shortest distance between each assembly deformation area and the selected point of the central deformation area after the design three-dimensional image is assembled, and simultaneously obtaining the volume data of each assembly deformation area and the volume data of the inner mold hinge connection, and importing them into the assembly deformation abnormality index calculation formula to calculate the assembly deformation abnormality index, wherein the assembly deformation abnormality index calculation formula is: , where m is the number of assembly deformation regions, Vi is the volume of the i-th assembly deformation region, V is the volume of the inner mold hinge connection, and Li is the shortest distance of the i-th assembly deformation region relative to the selection point of the central deformation region after the design three-dimensional image is assembled. It should be noted here that since the shape of the region has been obtained, most of the existing image processing software can directly obtain the volume of the region. At the same time, the assembly deformation anomaly index not only analyzes the proportion of the deformation at the inner mold hinge connection to the inner mold hinge connection, but also analyzes the degree of deformation aggregation through the distance of the deformation variable. The deformation anomaly is comprehensively analyzed by combining the degree of deformation aggregation and the proportion of the deformation at the inner mold hinge connection to the inner mold hinge connection;

[0051] S24. If the calculated assembly deformation anomaly index is compared with the set assembly deformation anomaly threshold, if the calculated assembly deformation anomaly index is greater than or equal to the set assembly deformation anomaly threshold, it means that the inner mold hinge is abnormal and cannot be assembled. If the calculated assembly deformation anomaly index is less than the set assembly deformation anomaly threshold, it means that the inner mold hinge is normal and can be assembled. It should be noted that since the inner mold hinge connection is often damaged during production, transportation or storage, it is necessary to analyze the state of the inner mold hinge before assembly. At the same time, the value of the assembly deformation anomaly threshold here is as follows: obtain 500 groups of inner mold hinge state data, import them into the assembly deformation anomaly index calculation formula to calculate the assembly deformation anomaly index, and hire experts to evaluate whether these inner mold hinges are abnormal, import the evaluation results and the assembly deformation anomaly index into the fitting software, and output the assembly deformation anomaly threshold that meets the highest evaluation accuracy;

[0052] S3, importing the acquired vibration data and deformation data of the connection position in the assembly process into the assembly process abnormality analysis model to perform assembly process abnormality analysis;

[0053] In a specific embodiment, importing the acquired vibration data and deformation data of the connection position in the assembly process into the assembly process abnormality analysis model to perform assembly process abnormality analysis includes the following specific steps:

[0054] S31, obtaining the vibration amplitude and vibration frequency data of the connection between the two inner mold hinges during the assembly process, and importing the obtained vibration amplitude and vibration frequency data of the connection between the two inner mold hinges during the assembly process into the vibration abnormality index calculation formula to calculate the vibration abnormality index, wherein the vibration abnormality index calculation formula is: , where T is the assembly time, dt is the time integral, zat is the vibration amplitude of one of the inner mold hinge connections at time t, zbt is the vibration amplitude of the other inner mold hinge connection, and zm is the vibration amplitude safety value. The vibration amplitude and vibration frequency of the two inner mold hinge connections during the assembly process do not correspond, which will lead to assembly misalignment. Therefore, the vibration amplitude and vibration frequency of the inner mold hinge connection are analyzed in correspondence, and the abnormal situation of assembly misalignment is analyzed. The vibration here refers to the vibration of the hinge connection caused by the operation or movement speed of the mobile equipment during assembly.

[0055] S32, obtaining image data of the wear position at the connection between the two inner mold hinges during the assembly process, obtaining the volume of the wear position and importing it into the assembly wear abnormality index calculation formula to calculate the assembly wear abnormality index, wherein the assembly wear abnormality index calculation formula is: , where M is the number of wear locations, and dj is the volume of the jth wear location;

[0057] S4, analyzing the assembly effect by acquiring the assembly deformation abnormality analysis results and the assembly process abnormality analysis results;

[0058] In a specific embodiment, performing assembly effect analysis by acquiring assembly deformation abnormality analysis results and assembly process abnormality analysis results includes the following specific contents:

[0059] Obtain the calculated assembly deformation abnormality index and assembly process abnormality index and substitute them into the assembly effect abnormality index calculation formula to calculate the assembly effect abnormality index, wherein the assembly effect abnormality index calculation formula is: , where exp() is the power of the natural constant e;

[0060] S5. Judging the success of assembly based on the assembly effect obtained through analysis, and giving an early warning for the unsuccessful assembly process;

[0061] In a specific embodiment, judging whether the assembly is successful based on the assembly effect obtained by analysis and giving an early warning for an unsuccessful assembly process include the following specific contents:

[0062] Obtain the calculated assembly effect abnormality index and compare it with the set assembly effect abnormality threshold. If the calculated assembly effect abnormality index is greater than or equal to the set assembly effect abnormality threshold, it means that the assembly process is abnormal, and the maintenance personnel are reminded to perform maintenance warnings on the inner mold hinge. If the calculated assembly effect abnormality index is less than the set assembly effect abnormality threshold, it means that the assembly process is normal, and the next step of bolt fixing is carried out.

[0063] The advantages of this embodiment over the prior art are as follows: by performing an abnormal assembly deformation analysis on the inner mold hinge connection before assembly, and performing an abnormal assembly process analysis through the vibration data and deformation data of the connection position during the assembly process, and then comprehensively analyzing the deformation of the inner mold hinge and the abnormal conditions of the assembly process to predict and analyze the assembly results, the safety of the assembly process is improved and the efficiency of the assembly is guaranteed.
