[0058] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0059] The terms "first", "second", etc. in the specification and claims of the present application and the above drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed or can optionally include other steps or units inherent to the process, method, product or device.

[0060] Reference to“an embodiment” or“the embodiment” in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in one embodiment” or“in at least one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another.

[0061] In order to better understand the assembly error monitoring and identification method for the fabricated subway station provided by the embodiments of the present application, first of all, the assembly error monitoring and identification method for the fabricated subway station in the prior art will be briefly introduced. In the prior art, when identifying the assembly error, the attribute information of the installed pipe piece is usually collected, and the assembly error is calculated based on the size, angle, joint gap and position, etc., and then the error is optimized by using genetic algorithm, etc., and finally the error that can be used for construction is obtained. However, when the above method is implemented, the size information of the installed pipe piece is uniformly extracted to calculate the joint error, and the error is optimized, which cannot be batched and real-time error optimized according to the construction error in the actual construction environment, so in the actual construction, if the actual construction error is within the error allowable range, but the high value in the error range, the final error is likely to be large due to the accumulation of error, which may cause a series of assembly problems, such as assembly failure or safety hazards after assembly, etc.

[0062] To solve the above problems, the embodiments of the present application provide an assembly error monitoring and identification method for a fabricated subway station, which can extract the current attribute information of each to-be-installed pipe piece and the installation parameter information in the fabricated subway station, determine the actual installation error information by combining the current attribute information, the preset attribute information and the installation parameter information, so as to obtain more real installation error, and error confirmation is needed each time of installation, realizing real-time extraction and correction of error, and improving the accuracy and reliability of the whole installation.

[0063] Please refer to Figure 1 , Figure 1 A flowchart of the assembly error monitoring and identification method for the fabricated subway station provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the method comprises the following steps. Figure 1

[0064] 101, obtaining the current attribute information of the to-be-installed pipe piece in the fabricated subway station, and obtaining the installation parameter information in the fabricated subway station.

[0065] ​The current attribute information of the to-be-installed segment can be used to indicate various feature data of the segment to be installed at the moment, such as actual size (length, width, height) of the segment, actual angle (inclination angle and rotation angle of the edge angle), and other physical attribute information.

[0066] The installation parameter information in the fabricated subway station can involve some setting data related to segment installation in the construction process of the fabricated subway station, for example, installation position coordinates, installation sequence, and environmental parameters (such as temperature and humidity) during installation.

[0067] The current attribute information of the to-be-installed segment in the fabricated subway station and the installation parameter information in the station can be obtained through corresponding measurement means and data collection channels, so that the basic data can be collected, and original data can be provided for error analysis in subsequent steps.

[0068] 102. Determine the installation error information of the to-be-installed segment according to the current attribute information, the preset attribute information, and the installation parameter information.

[0069] The preset attribute information can be used to indicate the standard attribute data preset for each fabricated segment in the design stage of the fabricated subway station. The preset attribute information can include, but is not limited to, ideal size (including design values of length, width, and height) of the segment, accurate angle (such as design upward inclination angle and design rotation angle in the horizontal plane) of the edge angle, and standard joint gap width.

[0070] It can be understood that the preset attribute information can be used as a reference to compare with the current attribute information of the to-be-installed segment obtained in the actual construction process, so that the attribute deviation of the segment in the production, transportation, or other links can be clearly determined, and important reference basis can be provided for subsequent accurate calculation of installation error information and taking of corresponding adjustment measures.

[0071] The installation error information can be used to indicate the deviation data of the to-be-installed segment in the actual installation process relative to the ideal installation state. The installation error information can include, but is not limited to, position, angle, and joint errors caused by differences between the segment attribute and the preset attribute and various factors in the installation process.

[0072] The installation error information of the to-be-installed segment can be determined according to the collected current attribute information, the pre-set standard attribute information and the installation parameter information, and by using a pre-set algorithm or calculation model. It can be understood that this process needs to comprehensively analyze and process various data to accurately obtain the error condition. For details, please refer to the detailed description in the following embodiments. The present application will not be described here.

[0073] 103. adjusting the initial installation parameter of the to-be-installed segment according to the installation error information to obtain an actual installation parameter.

[0074] Further, the initial installation parameter of the to-be-installed segment is adjusted according to the calculated installation error information, so that the actual installation parameter that meets the actual installation requirement can be obtained, and the segment can be accurately installed within the allowable error range.

[0075] In the existing method, only the size information of the installed segment is uniformly extracted to calculate the splicing error and optimize, without considering the construction error in the actual construction environment for batch and real-time error optimization. The present method can accurately extract the current attribute information and installation parameter information of each to-be-installed segment during installation, determine the actual installation error information in combination with the pre-set attribute information, realize real-time extraction and correction of the error, effectively avoid the accumulation problem of the construction error within the allowable range but at a high value, greatly reduce the final error, significantly improve the accuracy and reliability of the overall installation of the assembled subway station, and reduce the occurrence of assembly failure and safety hazards after assembly.

[0076] In the present example, the current attribute information of the to-be-installed segment in the assembled subway station is obtained, the installation parameter information in the assembled subway station is obtained, the installation error information of the to-be-installed segment is determined according to the current attribute information, the pre-set attribute information and the installation parameter information, the initial installation parameter of the to-be-installed segment is adjusted according to the installation error information, and an actual installation parameter is obtained. Therefore, the installation error information can be determined according to the attribute information of the to-be-installed segment and the installation parameter information in the subway station, and the installation parameter is adjusted using the installation error information to obtain an actual installation parameter, which improves the accuracy during subsequent assembly.

[0077] In one possible implementation, the installation error information of the to-be-installed segment is determined according to the current attribute information, the pre-set attribute information and the installation parameter information, including:

[0078] A1. determining attribute offset information according to the current attribute information and the pre-set attribute information;

[0079] A2, determining assembling error information of the installed segment according to the installation parameter information;

[0080] A3, determining installation error information of the to-be-installed segment according to the assembling error information and the attribute offset information.

[0081] The attribute offset information can be used to indicate the difference data between the current attribute information of the to-be-installed segment and the preset attribute information in terms of size, angle, etc. The attribute offset information can reflect the deviation degree of the actual state of the segment from the ideal design state. For example, the difference between the actual length of the current segment and the preset length, the difference between the actual corner angle and the preset angle, etc. can all be attribute offset information.

[0082] Optionally, the current attribute information of the to-be-installed segment and the preset attribute information can be compared and calculated to determine the above-mentioned attribute offset information. It can be understood that this step needs to accurately calculate and analyze the difference of each attribute data of the segment.

[0083] The assembling error information of the installed segment can be used to indicate the data obtained by analyzing and counting the errors in position, angle, joint gap, etc. of the installed segment in the splicing process based on the installation parameter information. The assembling error information of the installed segment can reflect the actual situation in the previous installation process, which has important reference value for subsequent segment installation.

[0084] Optionally, the installation parameter information obtained can be used to calculate the assembling error information of the installed segment in the splicing process by using a preset analysis method and model. It can be understood that this step needs to consider various factors in the installation process and the actual installation state of the installed segment. Specifically, assuming that the installation parameter information includes the actual installation position coordinates and the actual installation angle of the installed segment, and the ideal installation position coordinates and the ideal installation angle can be obtained, then the assembling error information of the installed segment can be the difference between the actual installation position coordinates and the ideal installation position coordinates, and the difference between the actual installation angle and the ideal installation angle, which is not limited in the present application.

[0085] Further, the calculated assembling error information and attribute offset information can be comprehensively processed, such as determining the logical relationship between the two to further integrate the above two information, so as to determine the installation error information of the to-be-installed segment. It can be understood that this step can fully consider the mutual influence and correlation between the two to obtain accurate installation error information. Optionally, the specific content of determining the installation error information of the to-be-installed segment according to the assembling error information and the attribute offset information can be referred to the detailed description in the following embodiments, which will not be repeated here.

[0086] In this example, the way to determine the installation error information is no longer limited to the attribute analysis of a single segment, but also takes into account the assembly error information of the installed segments. The changes in the properties of the segments and the actual error conditions in the previous installation process are comprehensively combined, which can more accurately reflect the complex situation in actual construction, making the installation error information of the to-be-installed segment determined finally more real and reliable. Compared with the traditional method, the problem of cumulative overall installation error caused by incomplete local error analysis can be more effectively avoided, thereby improving the installation quality and stability of the prefabricated subway station, reducing the safety hazards and subsequent maintenance costs caused by installation errors, and improving the efficiency and reliability of the entire project.

[0087] In one possible implementation, the installation error information of the to-be-installed segment is determined according to the assembly error information and the attribute offset information, comprising:

[0088] B1, extracting attribute error information and installation error information from the assembly error information;

[0089] B2, constructing a reference installation error information map according to the construction error information;

[0090] B3, determining a target installation error information map according to the attribute error information and the reference installation error information map;

[0091] B4, determining the current attribute error information according to the attribute offset information;

[0092] B5, determining the installation error information according to the target installation error information map and the current attribute error information.

[0093] The attribute error information can be the part of error data related to the deviation of the properties of the segments (such as height, width, length, inclination angle, rotation angle, etc.) separated from the existing assembly error information. The attribute error information can reflect the influence of the difference between the actual value and the ideal value of the properties of the installed segments on the assembly.

[0094] The installation error information can be the error data of the relative position or angle between the segments caused by the installation process (such as installation position, installation sequence, installation process, etc.) in the assembly error information. Optionally, the collected assembly error information can be analyzed and screened. Specifically, a data table can be established to list different types of error data, and the segment number or installation position information can be marked, so that the attribute error information and the installation error information can be accurately separated for subsequent processing and utilization.

[0095] The construction error information can be used to indicate a collection of various error data generated by the installed segment during the actual construction in the construction process of the fabricated subway station. The construction error information can include, but is not limited to, size deviation, angle deviation, joint gap deviation, and position deviation of the segment, and can cover errors introduced in various links from segment production, transportation to installation.

[0096] The reference installation error information diagram can be understood as a visualized or data-based information diagram constructed based on the construction error information. The reference installation error information diagram can be used to intuitively show the error distribution and trend of the installed segment during the construction process, and can provide a basis for subsequent determination of the target installation error information diagram. Optionally, the reference installation error information diagram can be constructed by using the construction error information accumulated during the construction process and through a preset algorithm or drawing method, so that the complex error data can be presented in an intuitive form.

[0097] The target installation error information diagram can be used to indicate a targeted error information visualization obtained by adjusting and converting the existing reference installation error information diagram in combination with the attribute error information extracted from the assembly error information.

[0098] The target installation error information diagram can comprehensively reflect the ideal installation error distribution and trend considering the influence of the segment attribute error under the current construction state, and can provide a key reference for accurately determining the installation error information of the to-be-installed segment, helping the construction personnel to intuitively understand the difference between the actual installation and the ideal state, thereby more effectively guiding the subsequent installation work and improving the accuracy and reliability of the overall installation.

[0099] The current attribute error information can be used to indicate error data determined according to the difference between the current attribute information of the to-be-installed segment and the preset attribute information. The current attribute error information can reflect the deviation of the segment in size, angle, and other attributes relative to the design standard at the current time. For example, if the actual length of the to-be-installed segment is longer than the preset length by a certain value, or the actual inclination angle of a certain corner deviates from the design inclination angle, the difference value after calculation and arrangement can constitute the current attribute error information.

[0100] The current attribute error information is crucial for accurately evaluating the actual state of the segment and subsequently determining the installation error information and adjusting the installation parameters, and can help the construction personnel to timely find the attribute problems of the segment and take corresponding measures to correct the deviation, thereby ensuring the assembly quality of the fabricated subway station. Further, the target installation error information diagram and the current attribute error information can be comprehensively analyzed and calculated to finally determine the installation error information of the to-be-installed segment, which can provide a basis for subsequent installation parameter adjustment.

[0101] In this example, through detailed decomposition and utilization of the assembly error information, the root cause of the error can be better understood, and the problems of the segment itself or the installation process can be clearly distinguished; by constructing a reference installation error information graph and further determining a target installation error information graph, the error situation during construction can be clearly seen, so that construction personnel can better grasp the overall construction quality and trend; by combining attribute offset information to determine the final installation error information, the actual state and construction history of the segment are fully considered, which can improve the accuracy and reliability of installation error determination, thereby effectively reducing error accumulation during installation, improving the installation precision and stability of the prefabricated subway station, ensuring engineering quality, and reducing maintenance costs and safety risks in the later period.

[0102] In one possible implementation, the reference installation error information graph is constructed according to the construction error information, including:

[0103] C1, extracting construction error information of k installed segments from the construction error information to obtain k first installation error information;

[0104] C2, and extracting overall installation error information of the k installed segments before installation from the construction error information to obtain k overall installation error information;

[0105] C3, installation error information graph construction according to k overall installation error information, k first installation error information and corresponding segment identification information, to obtain a reference installation error information graph.

[0106] The k first installation error information can be used to indicate the part of error information about the k installed segments generated during the installation process, which is directly related to the installation operation. For example, the positioning deviation of the segment during installation, the angle fine-tuning error during splicing, etc. The k first installation error information can reflect the influence of the installation link on the final position and attitude of the segment.

[0107] The k overall installation error information can be used to indicate the related information of the comprehensive error situation of the k installed segments before installation. For example, the deviation information of the overall size and shape of the segment due to the mold precision problem in the manufacturing process, vibration or collision during transportation, etc. The k overall installation error information can reflect the initial state error of the segment before entering the installation link.

[0108] The segment identification information can be a number or a mark used to distinguish each segment. Through the segment identification information, the error information of different segments can be accurately corresponded, so as to facilitate data management and analysis, thereby ensuring that the error data of each segment can be accurately integrated and displayed when constructing the installation error information map.

[0109] Further, the obtained k overall installation error information, k first installation error information and corresponding segment identification information are integrated and associated, and by using drawing software or algorithm, according to certain rules and layout, the above data can be converted into a visual installation error information map, that is, the above reference installation error information map can be obtained.

[0110] In this example, by systematically arranging and summarizing the error data of the installed segments, the complex construction error information is presented in the form of intuitive graphics, so that the construction personnel can quickly and clearly understand the error situation of different segments at different stages, which is convenient for discovering error rules and trends. Based on the accurate association of the segment identification information, the accuracy and traceability of the error data are ensured, which provides a reliable reference for subsequent error analysis and new segment installation, helps to improve the construction efficiency, prevent and correct possible installation problems in advance, thereby ensuring the assembly quality and overall structural stability of the prefabricated subway station, and reducing the safety hazards and maintenance costs caused by error accumulation.

[0111] In one possible implementation, the determining the target installation error information map according to the attribute error information and the reference installation error information map comprises:

[0112] D1, extracting k attribute error information of installed segments from the attribute error information, to obtain k first attribute error information;

[0113] D2, determining an influence factor of the k first attribute error information on the installation error information, to obtain k error influence factors;

[0114] D3, performing error conversion processing on the reference installation error information map according to the k error influence factors and the k first attribute error information, to obtain the target installation error information map.

[0115] The first attribute error information can be used to indicate the selected part of the attribute error information related to the k specific installed segments. The first attribute error information can focus on the attribute deviation of the k specific installed segments, so as to more targetedly analyze the influence of the attribute deviation on the installation error.

[0116] The error influence factor can be used to measure a quantitative index of the influence degree of each first attribute error information on the final installation error information. The error influence factor can reflect the relative importance of the attribute error in the whole installation error system, and can be further calculated or determined according to experience by comprehensively considering various factors such as the position of the pipe piece in the structure, the stress condition and the like.

[0117] Further, according to the k error influence factors and the k first attribute error information calculated, the reference installation error information map is subjected to error conversion processing in a targeted manner, and the data and the trend in the reference installation error information map are adjusted to integrate the influence of the attribute error, so as to generate a target installation error information map.

[0118] Optionally, the process of error conversion processing the reference installation error information map according to the k error influence factors and the k first attribute error information to obtain the target installation error information map can refer to the following formula:

[0119]

[0120] E tj may represent the jth target installation error information in the target installation error information map, i.e. the installation error information after error conversion processing; E 0j may represent the jth reference installation error information in the reference installation error information map, i.e. the installation error information before error conversion processing; j can represent the index of the installation error information; i can represent the index of the installed pipe piece; k can represent the number of the installed pipe pieces; α ij may represent the influence factor of the first attribute error information of the ith installed pipe piece on the installation error information; ΔA ij may represent the jth first attribute error information of the ith installed pipe piece.

[0121] It can be understood that the first attribute error information of the ith installed pipe piece can be ΔA i , and the influence factor α i may be calculated according to the following formula: α i = ΔA i / (ΔA i + ΔA i + ΔA i + ΔA i + ΔA i + …). i i i ​​​

[0122] In this example, the method provided by the embodiment of the application breaks the limitation of traditional single installation error analysis, comprehensively considers attribute error information, accurately extracts and analyzes first attribute error information and determines its influence factor, can more accurately evaluate the potential influence of the actual state of the installed segment on subsequent installation, and can generate target installation error information map based on this to provide more targeted and accurate guidance for construction personnel, help to adjust the installation strategy in advance in the subsequent installation process, effectively reduce the installation deviation caused by attribute error accumulation, improve the overall installation precision and quality of the prefabricated subway station, ensure the structural stability and safety of the project, and reduce the maintenance cost and potential risk in the later period.

[0123] Consistent with the above embodiments, please refer to Figure 2 , Figure 2 A structural schematic diagram of a terminal provided by the embodiment of the application is shown in Figure 2 , which includes a processor, an input device, an output device and a memory, and the processor, the input device, the output device and the memory are connected to each other, wherein the memory is used to store a computer program, the computer program includes program instructions, and the processor is configured to invoke the program instructions, and the above program includes instructions for executing the following steps;

[0126] Adjust initial installation parameters of the to-be-installed segment according to the installation error information to obtain actual installation parameters.
