[0002] Basket construction is a critical step in modern bridge construction, and its safety and efficiency are crucial to the overall project progress and quality. As bridge structures evolve toward larger spans and greater complexity, safety monitoring technology for basket construction has become a key focus of the industry. Traditionally, the safety of basket construction relies primarily on manual inspections and empirical judgment. However, this approach struggles to meet the precision and real-time requirements of modern bridge construction, necessitating the development of more efficient and reliable monitoring methods.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] In order to facilitate understanding of the technical solutions proposed in this application, several elements that will be introduced in the description of this application are first introduced here. It should be understood that the following introduction is only for the convenience of understanding these elements, so as to understand the content of the embodiments of this application, and does not necessarily cover all possible situations.

[0022] The hanging basket is the primary equipment used in cantilever construction and can be categorized by structural form into four types: truss, cable-stayed, steel-type, and hybrid. Based on the technical requirements for concrete cantilever construction and the design drawings' requirements for the hanging basket, a comprehensive comparison of the various types of hanging baskets was conducted, including their characteristics, weight, steel type, and construction techniques. The design principles for the hanging basket include light weight, simple structure, sturdiness and stability, easy movement and assembly and disassembly, strong reusability, and minimal deformation under load. Furthermore, ample space beneath the hanging basket provides a large working surface, facilitating rebar and formwork construction operations.

[0023] The present application embodiment provides a method for monitoring the safety of bridge hanging basket construction, such as Figure 1 As shown, the method provided in the embodiment of the present application is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S104, wherein: Step S101: Obtain current detection data and current wind speed data corresponding to the current hanging basket.

[0024] The current detection data includes the stress, inclination, and displacement corresponding to the current hanging basket at the current moment. The current wind speed data is the wind speed corresponding to the current cycle, which starts at the current moment. The current wind speed data can be obtained by obtaining weather forecast data for the current hanging basket location, or by communicating with an on-site anemometer through electronic equipment to obtain the current wind speed.

[0025] Specifically, the electronic device establishes a communication connection with various sensors installed on the basket (such as stress sensors, tilt sensors, and displacement sensors) to read the current stress, tilt, and displacement data collected by these sensors in real time, which is the current detection data. These sensors transmit this data to the electronic device via wired or wireless means for storage and processing.

[0026] Step S102: Determine the degree of influence of the current wind speed data on the current detection data.

[0027] Among them, the degree of influence indicates the size and significance of the effect of the current wind speed data on the current detection data (stress, inclination, displacement), which is used to measure the impact of wind speed on the state of the hanging basket.

[0028] Specifically, in this embodiment, determining the degree of influence of the current wind speed data on the current detection data includes: Obtain the historical data of the current hanging basket, including the historical detection data corresponding to the historical detection time and the historical wind speed data; Perform time domain and frequency domain analysis on the historical data to obtain the time domain relationship between each detection sub-data and wind speed data, as well as the frequency domain eigenvector matrix corresponding to the historical data. The detection sub-data is one of stress, inclination, and displacement. Based on the time domain relationship and the frequency domain eigenvector matrix, the degree of influence of the current wind speed data on the current detection data is determined.

[0029] Specifically, historical data related to the current basket can be obtained from the basket database corresponding to the basket. This historical data includes historical detection data such as stress, inclination, and displacement collected by sensors installed on the basket at different historical detection moments in the past, as well as historical wind speed data recorded by the anemometer at the same moment. Furthermore, for each detection sub-data (stress, inclination, displacement), its historical data series that changes over time is compared and analyzed with the corresponding historical wind speed data series. By calculating correlation coefficients, drawing time series curves, and other methods, the changing trends and mutual relationships between the detection sub-data and wind speed data in the time dimension can be observed. For example, when the wind speed changes, how does the stress data change accordingly? Is there an immediate response or a certain delay? This can determine the time domain relationship between the detection sub-data and the wind speed data.

[0030] The entire historical data set, including historical detection data and historical wind speed data, is transformed into the frequency domain using methods such as Fourier transform. After converting the time domain data into the frequency domain, the frequency characteristics are extracted to form frequency domain eigenvectors. For different historical data records, these frequency domain eigenvectors are combined to form a frequency domain eigenvector matrix. This matrix reflects the distribution and characteristics of the historical data at different frequency components, facilitating analysis of potential connections between wind speed data and detection sub-data from a frequency perspective.

[0031] Furthermore, an impact assessment model can be established, taking the time domain relationship and the frequency domain eigenvector matrix as input. The impact assessment model first analyzes whether the change trend between the current wind speed data and the current detection data is consistent with the time domain relationship in the historical data, as well as the magnitude of the change, based on the time domain relationship. Then, the frequency domain eigenvector matrix is ​​used to compare the similarity between the frequency domain features of the current data and the frequency domain features of the historical data. If the frequency domain features of the current data are similar to the frequency domain features in the historical data that show that high wind speed has a significant impact on the detection data, it is considered that the current wind speed data has a high degree of influence on the current detection data; conversely, if the difference is large, the degree of influence is low. The impact degree output by the impact assessment model is obtained. The impact assessment model is trained using a large number of time domain relationship samples, frequency domain eigenvector matrix samples, and impact degree samples.

[0032] Specifically, in this embodiment, the historical data is subjected to time domain analysis and frequency domain analysis to obtain the time domain relationship between each detection sub-data and the wind speed data and the frequency domain eigenvector matrix corresponding to the historical data, including: For each detection sub-data, obtain the historical pouring stage, historical detection sub-data and historical wind speed data corresponding to each historical detection moment; determine the historical basic sub-data corresponding to the historical pouring stage; calculate the historical detection difference between the historical basic sub-data and the corresponding historical detection sub-data corresponding to each historical detection moment, and based on the historical detection difference and the corresponding historical wind speed data corresponding to each historical detection moment, perform time domain analysis on the historical detection difference and the corresponding historical wind speed data to obtain a time domain function relationship with the historical inspection moment as the horizontal axis and the historical ratio as the vertical axis, where the historical ratio is the ratio between the historical detection difference and the corresponding historical wind speed data; Frequency domain analysis is performed on each historical sub-data and historical wind speed data in the historical data to obtain the frequency domain eigenvectors corresponding to each historical sub-data and historical wind speed data, and the frequency eigenvectors are integrated to obtain the frequency domain eigenvector matrix corresponding to the historical data.

[0033] Within the acquired historical data for the current hanging basket, operations are performed separately on the three detection sub-data: stress, inclination, and displacement. For each detection sub-data, the historical pouring stage information corresponding to the historical detection moment (e.g., whether it was at the beginning, middle, or end of the beam segment pouring) is extracted, along with the specific value of the detection sub-data at that moment (i.e., the historical detection sub-data), and the historical wind speed data at the same moment. Furthermore, stress is directly affected by pouring weight. The greater the pouring volume and the more uneven the distribution, the more significant the stress change. The inclination is highly sensitive to pouring eccentricity, and unilateral pouring can easily cause the hanging basket to tilt. Displacement increases linearly with pouring progress (elastic deformation). Therefore, each detection sub-data is related to the pouring stage, and the pouring weight varies in different pouring stages. Therefore, the pouring stages can be divided into initial pouring stage, mid-pouring stage, and late pouring stage. Based on the acquired historical pouring stage information and referring to pre-set rules (which can be based on engineering experience and design specifications), the historical basic sub-data corresponding to each historical pouring stage is determined. For example, for the initial pouring stage, a theoretical base value of stress, inclination, or displacement is determined as the historical basic sub-data based on the designed initial stress state and structural characteristics of the hanging basket. Since each pouring process is based on pre-set pouring instructions, each pouring process is similar or identical. The impact on each detection sub-data in each pouring stage of each pouring process is similar or identical. Therefore, the basic sub-data corresponding to each historical pouring stage can be determined based on pre-set rules.

[0034] Furthermore, for each historical detection moment, the historical basic sub-data corresponding to that moment is subtracted from the historical detection sub-data to obtain the historical detection difference. For the historical detection difference and the corresponding historical wind speed data obtained at each historical detection moment, time domain analysis methods are used, such as calculating correlation coefficients and drawing time series curves. By analyzing how these data change over time (historical detection moments), the ratio between the historical detection difference and the historical wind speed data (i.e., the historical ratio) is calculated. A function curve is then drawn with the historical detection moment as the horizontal axis and the historical ratio as the vertical axis to obtain the time domain function relationship between them. This relationship reflects the correlation between wind speed changes and relative changes in the hanging basket detection sub-data at different historical detection moments.

[0035] Furthermore, frequency domain analysis is performed on each historical detection sub-data (historical data corresponding to stress, inclination, and displacement) and historical wind speed data within the historical data. Frequency domain analysis methods such as Fourier transform are used to convert the time domain data into frequency domain data. In the frequency domain, frequency characteristics of the data, such as frequency components and energy distribution, are extracted to form a frequency domain eigenvector corresponding to each data sequence. For example, for the historical stress data sequence, Fourier transform is used to obtain characteristics such as its energy distribution at different frequencies, forming a frequency domain eigenvector. The frequency domain eigenvectors corresponding to each historical sub-data (frequency domain eigenvectors corresponding to stress, inclination, and displacement) and historical wind speed data are then arranged and combined in a specific order (e.g., according to the order of data type) to form a matrix, namely the frequency domain eigenvector matrix.

[0036] Furthermore, in this embodiment, based on the time domain relationship and the frequency domain eigenvector matrix, determining the degree of influence of the current wind speed data on the current detection data includes: Determining the influence sub-degree of the current wind speed data on each detection sub-data based on the time domain relationship, and determining a first influence degree of the current wind speed data on the current detection data based on each influencing sub-data; Inputting the frequency domain eigenvector matrix into the recurrent network model and obtaining the second influence degree output by the recurrent network model; Based on the first influence degree and the second influence degree, the influence degree of the current wind speed data on the current detection data is determined.

[0037] According to the obtained time domain relationship (i.e., the time domain function relationship with the historical detection time as the horizontal axis and the historical ratio as the vertical axis), the current wind speed data is substituted into the time domain function relationship. For each detection sub-data (stress, inclination, displacement), the change in the historical ratio corresponding to the current wind speed data is analyzed. According to the change amplitude of the historical ratio and the similarity with the change pattern in the historical data, the influence of the current wind speed data on each detection sub-data is determined. The influence of each detection sub-data is comprehensively considered, and the influence of each detection sub-data is integrated by weighted average method. Among them, stress, inclination, and displacement each have different preset weights, and the weighted average is calculated to determine the first influence of the current detection data corresponding to the current wind speed data.

[0038] The frequency-domain eigenvector matrix is ​​then input into a pre-trained recurrent network model (such as a long short-term memory (LSTM) network or a gated recurrent unit (GRU)). This recurrent network model has been trained on a large amount of historical data and has learned the relationship between the frequency-domain eigenvectors and the degree of wind speed's impact on the basket's detection data. The recurrent network model processes and analyzes the input frequency-domain eigenvector matrix. Through internal neuron calculations and parameter adjustments, it outputs a numerical value representing the second degree of impact of the current wind speed data on the current detection data. Electronic equipment then captures and records this second degree of impact output by the recurrent network model.

[0039] Furthermore, an average value of the first influence degree and the second influence degree is calculated to obtain the influence degree of the current wind speed data on the current detection data.

[0040] Step S103: Based on the current detection data, the impact degree and the current wind speed data, predict the safety situation of the current hanging basket in the current cycle.

[0041] Among them, the safety situation is safe or unsafe.

[0042] Specifically, a trained safety prediction model can be used, taking the current test data (stress, inclination, displacement), the determined impact level, and the current wind speed data as input parameters. This safety prediction model can be trained using a machine learning algorithm. Based on the input data, the model analyzes whether various basket indicators exceed safety thresholds. For example, if the stress exceeds the material's allowable stress value, or if the inclination and displacement exceed the specified safety range, and considering the significant impact of the current wind speed data, the model will predict that the basket is in an unsafe state for the current cycle. If all indicators are within the safe range, the basket is deemed safe.

[0043] In this embodiment, based on the current detection data, the impact level, and the current wind speed data, the safety status of the current hanging basket in the current cycle is predicted, including: Obtain the detection threshold corresponding to the current detection data, and determine whether the current detection data is within the corresponding detection threshold; If the current detection data is not within the corresponding detection threshold, the safety condition of the current hanging basket in the current cycle is predicted to be unsafe; If the current detection data is within the corresponding detection threshold, the expected detection data of the current hanging basket in the current period is determined based on the impact degree and the current wind speed data, and the safety situation of the current hanging basket in the current period is predicted based on the expected detection data.

[0044] The detection threshold corresponding to each current detection data (any one of stress, inclination, and displacement) is obtained from the basket database corresponding to the current basket, and the specific value of the current detection data (any one of stress, inclination, and displacement) is compared with the corresponding detection threshold to determine whether the value of the current detection data is within the range specified by the detection threshold, for example, to determine whether the current stress value is within the range of the stress detection threshold.

[0045] Furthermore, if, after comparing the current test data with the detection threshold, any value of the current test data (stress, inclination, or displacement) is found to be outside the corresponding detection threshold, the current basket is judged to be unsafe for the current cycle. This is because even if any key indicator exceeds the safe range, it may pose a threat to the structural safety of the basket. Therefore, no further analysis is required and an unsafe prediction result is directly given.

[0046] When the current test data (stress, inclination, displacement) is determined to be within the corresponding detection threshold range, the possible changes in the basket's test data (stress, inclination, displacement) during the current cycle can be predicted, thereby deriving the estimated test data. The estimated test data (estimated stress, estimated inclination, estimated displacement) is then compared with the corresponding detection threshold. If all estimated test data are within the corresponding detection threshold range, the current basket's safety status for the current cycle is predicted to be safe. If any of the estimated test data exceeds the corresponding detection threshold range, the current basket's safety status for the current cycle is predicted to be unsafe.

[0047] Specifically, in this embodiment, based on the impact degree and the current wind speed data, the expected detection data of the current hanging basket in the current cycle is determined, including: Get the initial BIM model corresponding to the current hanging basket, and get the current pouring stage corresponding to the current hanging basket. The current pouring stage is the pouring stage of the current hanging basket in the current cycle. Input the current pouring stage into the initial BIM model to obtain the target BIM model; The impact degree, current detection data and current wind speed data are input into the target BIM model, and the detection data displayed by the target BIM model is obtained to obtain the expected detection data of the current hanging basket in the current cycle.

[0048] Specifically, the initial BIM model corresponding to the current hanging basket can be obtained from the hanging basket database corresponding to the current hanging basket. The initial BIM model contains various information of the hanging basket design stage, such as structural dimensions, material properties, connection methods, etc. At the same time, the current pouring stage of the current hanging basket in the current cycle is obtained from the construction management system, and the obtained current pouring stage information is input into the initial BIM model. The initial BIM model adjusts the relevant parameters and states in the initial BIM model according to the preset rules and the characteristics of the current pouring stage. For example, the load conditions borne by the hanging basket are determined according to the current pouring stage, and the corresponding load parameters in the model are adjusted; or information such as the solidification state of the concrete in the model is updated according to the pouring progress. After these adjustments, a target BIM model that reflects the actual state of the hanging basket in the current pouring stage is generated.

[0049] Furthermore, the previously determined impact of the current wind speed data on the current test data, the current test data (stress, inclination, displacement), and the current wind speed data are input into the target BIM model. The target BIM model utilizes its internal mechanical analysis and simulation modules to simulate the changes in the basket's operating state during the current cycle under the influence of the current wind speed and impact. Through calculation and analysis, the target BIM model derives the predicted values ​​of the basket's test data (stress, inclination, displacement) under these conditions and displays these predicted values. Electronic equipment captures this displayed test data as the predicted test data for the current cycle. The target BIM model is trained using a large amount of historical test data, historical wind speed data, and historical impact levels.

[0050] Step S104: Based on the security situation, determine whether to generate security alert information.

[0051] Specifically, a judgment is made based on the predicted safety status. If the safety status is "unsafe," a corresponding safety alert message is generated. This alert message may include the basket number, current problems (such as excessive stress or abnormal tilt angle), and the degree of danger. The alert message is sent to relevant construction managers and safety officers via display screens, SMS notifications, and voice alarms. If the safety status is "safe," no safety alert message is generated, and the basket's status continues to be monitored in real time.

[0052] In this embodiment, determining whether to generate security alert information based on the security situation includes: If the security situation is safe, no security alert message is generated; If the safety situation is unsafe, a safety alert message is generated and the target BIM model marked with expected detection data is displayed.

[0053] After completing the safety prediction for the current basket during the current cycle, the resulting safety status results are checked. If the safety status is displayed as "safe," meaning all predicted test data (stress, inclination, displacement) are within the corresponding detection thresholds, the basket is safe for the current cycle and presents no significant safety risks. At this point, no actions that would generate safety alerts are performed; instead, the basket status continues to be monitored in real time, acquiring and analyzing new test data according to the established process and frequency.

[0054] If the safety inspection result is "unsafe," it means that at least one of the expected test data (stress, inclination, or displacement) exceeds the corresponding detection threshold, indicating that the current gantry presents a safety hazard within the current cycle. At this point, a safety alert message containing relevant key information is generated based on the preset alert format and content template. This information may include the gantry's identification (such as its number), a specific description of the unsafe condition (for example, stress exceeding a threshold by X% or inclination exceeding the allowable range), the current expected test data (specific stress, inclination, and displacement values), possible risk consequences, and recommended countermeasures. The previously generated target BIM model is simultaneously retrieved and the relevant expected test data is annotated on the target BIM model. For example, information such as stress values ​​exceeding the threshold or abnormal inclination angles is annotated at the corresponding parts of the gantry structure, visually demonstrating the specific location and extent of the gantry's unsafe condition. The target BIM model with the annotated expected test data is then presented to relevant construction managers and safety officers via the electronic device's display or a connected display terminal, enabling them to quickly understand the gantry's safety status and make decisions.

[0055] The embodiment of the present application provides a method for monitoring the safety of bridge hanging basket construction. By synchronously collecting core parameters such as structural stress, inclination, displacement, and real-time wind speed data, the impact of environmental loads on the stability of the hanging basket is accurately quantified. A dynamic impact assessment model is introduced to couple wind speed changes with structural responses for analysis, effectively identifying the evolution trend of potential risks.
