[0052] As Figures 1 - 3 shown, the present invention provides a technical solution: a digital handover management platform for municipal engineering based on multi-source data fusion. The platform includes multiple data collection terminals, a data storage module, and a data processing module. The data collection terminals are used to collect multi-source data during the construction of municipal engineering. The data storage module is used to store the collected multi-source data. The data processing module includes:

[0053] A data fusion unit, which is used to receive real-time data from multiple data collection terminals, and perform time synchronization and spatial alignment processing on data from different sources to form a fused data set. It should be clear that in the embodiments of the present application, the data fusion unit is responsible for all the data from multiple data collection terminals, and the data comes from different sensors, devices, or systems. During the integration process, the data fusion unit needs to perform time synchronization and spatial alignment processing along with the data. Time synchronization is to ensure that data from different sources is comparable in time, while spatial alignment is to ensure the consistency of data in space. Time synchronization is achieved by setting a unique clock host to provide the same reference time for various sensors and calibrating their respective clock times according to the provided reference time. For each modality of data, high-level semantic features are extracted through specific feature extraction methods, and then alignment techniques are used to map the features of different modalities to a shared feature space, thereby achieving alignment between modalities. For time-series modality data, time alignment methods are used to align different modality time-series data, fuse them on the same time scale, and construct a graph model to describe the mutual relationship between multi-modal data. Then, graph matching and graph cut techniques are used for data alignment and fusion. In the present application, the nodes of the graph model represent different modalities, and the edges represent the similarity or correlation between modalities. Then, a neural network architecture is used to learn the alignment and expression between modalities, thereby achieving the fusion of multi-modal data.

[0054] A quality assessment unit, which is used to conduct real-time assessment on the construction quality, progress and safety of municipal engineering based on the unified dataset, and generate a quality assessment report. In this application, this unit can accept and integrate datasets from different sources, including real-time monitoring data, historical data, design drawings and construction plans during the construction process, and perform data cleaning, verification and standardization processing to ensure the accuracy and consistency of the data. Based on the dataset, quality assessment is carried out on each construction link of the municipal engineering, and the assessment content includes but is not limited to material quality, construction technology and construction process control, etc. Statistical methods are used to analyze the data, identify potential quality problems and put forward improvement suggestions.

[0055] A handover management unit, which is used to generate a digital handover document based on the quality assessment report, and support the review, determination and archiving of the handover document;

[0056] A visualization display unit, which is used to display the fusion dataset and quality assessment results in a customized manner and support user interaction operations. It should be clear that in the embodiment of this application, the quality assessment report is the basis for handover management. Through the fusion and analysis of multi-source data, a comprehensive assessment of the quality of municipal engineering is generated. The generation process of the quality assessment report needs to refer to the following formulas and indicators. Data quality indicators include data accuracy rate, recall rate, precision rate and F1 score, etc. The following are the calculation formulas for data quality indicators:

[0057] Accuracy rate: ;

[0058] Recall rate: ;

[0059] Precision rate: ;

[0060] F1 score: , where TP represents true positive, TN represents true negative, FP represents false positive, and FN represents false negative.

[0061] The data fusion unit includes:

[0062] A data preprocessing module, which is used to clean, denoise and convert the format of the received multi-source data;

[0063] A time synchronization module, which is used to align the timestamps of data from different sources;

[0064] A space alignment module, which is used to align the spatial coordinates of data from different sources based on geographical location information or BIM model data;

[0065] The data fusion algorithm module, based on deep learning algorithms, fuses the aligned data to generate a fused dataset. It should be clear that in this application, the data preprocessing module is the first step of data fusion, and its main function is to clean, denoise, and convert the format of the received water source data. This is achieved through the following methods: filling missing values with the mean of the feature column, where the filling value is equal to u, and u is the mean of the feature column. Then, find the k samples most similar to the missing value sample and fill it with the average of these samples. Calculate the Euclidean distance between all samples: , select K nearest neighbors, calculate their average as the filling value, construct a polynomial interpolation function through known points, and calculate the missing value: .

[0066] The time synchronization module is used to align the timestamps of data from different sources to ensure the consistency of data in the time dimension. For data with missing timestamps, linear interpolation or polynomial interpolation is used to fill the timestamps, and the timestamps of different data sources are aligned to the same time window. For example, second-level data is aligned to minute-level data by taking the average or maximum value. It should also be clear that in this application, the spatial alignment module is based on geographical location information or BIM model data to align the spatial coordinates of data from different sources, unifying the coordinates of different data sources into the same coordinate system. For irregularly distributed spatial data, Kriging interpolation or nearest neighbor interpolation is used, or it can also be achieved through the differences between sensor data or other spatial data and the geometric elements and expressions in the BIM model. In this application, the data fusion algorithm module, based on deep learning algorithms, fuses the aligned data to generate a fused dataset, uses CNN or LSTM to extract the spatial and temporal features of the data, fuses the extracted features through a fully connected layer or an attention mechanism, and remaps the fused features to the original data dimension to generate a fused dataset.

[0067] The quality assessment unit includes:

[0068] A quality index library for storing preset municipal engineering quality assessment indicators;

[0069] A data analysis module for calculating the values of various quality indicators based on the fused dataset;

[0070] A quality assessment model for comprehensively evaluating the construction quality, progress, and safety of municipal engineering based on the calculated quality indicator values and generating a quality assessment report.

[0071] It should be clear that in the embodiments of the present application, the quality index library is used to store preset quality assessment indicators for municipal engineering, and the indicators cover aspects such as construction quality, progress, and safety. The data analysis module calculates the values of various quality indicators based on the fused dataset. Before calculating the quality indicators, it is necessary to preprocess the fused dataset, and calculate various quality indicators according to the preprocessed data. The quality assessment model comprehensively assesses the construction quality, progress, and safety of the municipal engineering based on the calculated quality indicator values, and generates a quality assessment report.

[0072] The visualization display unit includes:
