[0028] Example 1
[0029] Figure 1 This is a schematic diagram of the structure of a digital twin panoramic display system of a rail transit signal system provided by the first embodiment of the present invention. This embodiment is applicable to the situation of panoramic display of rail transit signal systems at different stages. Figure 1 As shown, the system includes: a BIM model building module 110, a three-dimensional data simulation module 120, a data simulation platform 130 and a user interface module 140; the user interface module 140 is connected to the BIM model building module 110, the three-dimensional data simulation module 120, and the data simulation platform 130 respectively;
[0030] The BIM model building module 110 is used to build a BIM three-dimensional model of the rail transit signal system based on the equipment information of the rail transit signal system, and transmit the BIM model data of the BIM three-dimensional model to the three-dimensional data simulation module 120 and the data simulation platform 130 respectively;
[0031] The three-dimensional data simulation module 120 is used to obtain three-dimensional data of the rail transit signal system and environment, receive the BIM model data, and generate a virtual environment based on the BIM model data and the three-dimensional data; perform physical simulation of the rail transit signal system in the virtual environment to obtain physical simulation results of the rail transit signal system under different environmental conditions, and transmit the physical simulation results to the data simulation platform 130;
[0032] The data simulation platform 130 is used to obtain the operating data of the rail transit signal system in real time, and receive the BIM model data and the physical simulation results, perform digital twin simulation based on the operating data, the model data and the physical simulation data to obtain a digital twin model of the rail transit signal system, and perform intelligent analysis based on the digital twin model to obtain analysis results;
[0033] The user interface module 140 is used to display the BIM three-dimensional model, the physical simulation results and the analysis results.
[0034] Among them, equipment information refers to the equipment information of signal equipment in the rail transit signal system. Specifically, signal equipment includes but is not limited to core components such as signal machines, track circuits, interlocking equipment, and switches. The equipment information can be obtained through laser scanning, photogrammetry, CAD drawing data, etc. In an embodiment of the present invention, the BIM model establishment module 110 serves as the basic layer of the system. It constructs a BIM three-dimensional model of the rail transit signal system based on the equipment information of the rail transit signal system, and transmits the BIM model data of the BIM three-dimensional model to the three-dimensional data simulation module 120 and the data simulation platform 130 respectively. Among them, the BIM model data includes but is not limited to the geometric information, attribute parameters, topological relationships, etc. of the signal equipment in the rail transit signal system. It should be noted that the BIM three-dimensional model is a static three-dimensional model used to characterize the geometric shape, spatial distribution and topological relationships of the signal equipment in the rail transit signal system.
[0035] Based on the above embodiment, optionally, the BIM model building module 110 is further configured to obtain the control logic of the rail transit signal system from a control logic library, and embed the control logic into the BIM three-dimensional model in the form of parameterized rules.
[0036] The control logic includes, but is not limited to, signal state switching, track circuit occupancy detection, train route setting, etc. In an embodiment of the present invention, the BIM model building module 110 obtains the control logic of the rail transit signal system from the control logic library and embeds the control logic into the BIM three-dimensional model in the form of parameterized rules, enabling the BIM three-dimensional model to automatically adjust the status of the signal equipment according to different input conditions (such as train position, speed, etc.).
[0037] The three-dimensional data can be 3D scan data obtained by laser scanning the rail transit signal system and the external environment. Specifically, laser scanning technology can be used to collect detailed 3D data of the rail transit signal system equipment and environment. This scan data can be used to create a precise 3D model that reflects the geometric form of the environment. The 3D data can also be 3D data obtained by converting 2D images obtained by photogrammetry of the rail transit signal system and the external environment. Specifically, a high-precision camera can be used to photograph the signal equipment and the external environment to obtain a large number of 2D images. Then, through image matching and geometric reconstruction technology, the 2D images can be converted into 3D data. In an embodiment of the present invention, the 3D data simulation module 120 integrates BIM model data with external 3D data to construct a virtual environment. A physics engine is used to perform physical simulation of the rail transit signal system under different environmental conditions to obtain physical simulation results. Environmental conditions include, but are not limited to, heavy rain, high temperatures, and other environmental conditions. Physical simulation includes, but is not limited to, signal state switching simulation, track circuit occupancy detection simulation, and train operation simulation.
[0038] It is understandable that by conducting physical simulation of the rail transit signal system under different environmental conditions, the rail transit signal system can be simulated and optimized in real time, thereby improving the operation and maintenance management and decision support capabilities.
[0039] Operational data is used to characterize the real-time operational status of rail transit signal systems. Specifically, this operational data includes, but is not limited to, sensor data and device status data for each signal device, such as voltage and current of signal devices, traffic light status of signal machines, and device health status. In an embodiment of the present invention, the data simulation platform 130 receives BIM model data, physical simulation results, and real-time operational data, constructs a dynamic twin using a digital twin engine, and combines machine learning algorithms to perform fault prediction and performance analysis to generate analysis results. These analysis results include, but are not limited to, device health scores, maintenance priority lists, and system bottleneck diagnosis reports.
[0040] Based on the above embodiment, optionally, the data simulation platform is also used to preprocess the operation data, the model data and the physical simulation data, and to fuse the preprocessed operation data, the model data and the physical simulation data to obtain fused data.
[0041] In an embodiment of the present invention, the data simulation platform preprocesses the operating data, model data and physical simulation data. Preprocessing includes preprocessing operations such as data cleaning and data storage. Data cleaning includes but is not limited to preprocessing operations such as processing missing values, deduplication, and noise reduction. Data storage can be based on a time series database or a relational database. Furthermore, the preprocessed operating data, the model data and the physical simulation data are fused to obtain fused data. Specifically, time synchronization can be used to align data from different signal devices. Data fusion is performed based on the use of Bayesian fusion or Kalman filtering to improve data accuracy.
[0042] Based on the above embodiment, optionally, the data simulation platform includes a fault prediction unit; the fault prediction unit is used to input the fusion data into a pre-trained fault prediction model to obtain a fault prediction result.
[0043] The fault prediction model can be a machine learning model. Specifically, fault prediction models include, but are not limited to, LSTM and Random Forest models. In an embodiment of the present invention, the fused data is input into a pre-trained fault prediction model to obtain a fault prediction result, thereby predicting potential faults and effectively avoiding major failures. The fault prediction result refers to the tendency of signal equipment to fail, and can be expressed as the probability of the signal equipment failing.
[0044] In an embodiment of the present invention, the user interface module 140 provides data visualization. Specifically, the BIM model data, physical simulation results, and analysis results can be displayed in layers.
[0045] In some embodiments, optionally, the user interface module further includes a user interface creation unit, configured to create a user interface in response to a drag-and-drop operation on the visualization tool.
[0046] In an embodiment of the present invention, the user interface creation unit responds to a drag-and-drop operation on a visualization tool by dragging and dropping the visualization tool onto a canvas, automatically generating an interface layout and data binding logic, thereby forming a user interface. The visualization tools include, but are not limited to, signal status panels and track circuit monitoring charts, and are not limited here.
[0047] Based on the above embodiment, optionally, the system further includes a full life cycle management module, which is respectively connected to the BIM model establishment module and the data simulation platform; the full life cycle management module is used to obtain multi-dimensional data of the rail transit signal system at different stages from the BIM model establishment module and the data simulation platform, respectively, and track and manage the rail transit signal system based on the multi-dimensional data; the multi-dimensional data includes one or more of the design data, construction data, and operation and maintenance data of the rail transit signal system.
[0048] In an embodiment of the present invention, the full lifecycle management module acquires multidimensional data of the rail transit signal system at different stages through the BIM model building module and the data simulation platform. This multidimensional data includes one or more of the following: design data, construction data, and operation and maintenance data. Specifically, design data includes, but is not limited to, geometric parameters and equipment attributes; construction data includes, but is not limited to, progress logs and quality inspection records; and operation and maintenance data includes, but is not limited to, real-time sensor status data and historical fault data. The rail transit signal system can be tracked and managed based on this multidimensional data from different stages. Specifically, during the design phase, the BIM 3D model can be used to verify the rationality of the rail transit signal system's logical topology as reflected in the design data. For example, this can verify the compatibility of the track circuit layout with the interlocking logic. During the construction phase, the BIM 3D model can be compared with the construction data in real time to identify deviations between the two and issue warnings. For example, if the equipment installation position offset exceeds the limit, the system can be used to generate warnings. During the operation and maintenance phase, the real-time simulation results of the digital twin model can be combined to predict equipment lifespan.
[0049] Based on the above embodiment, optionally, the system further includes a monitoring and analysis module, which is connected to the data simulation platform; the data simulation platform is also used to transmit the fused data to the monitoring and analysis module; the monitoring and analysis module is used to perform a status analysis on the signal equipment in the rail transit signal system based on the fused data to obtain the status of the signal equipment; when the status of the signal equipment is abnormal, the signal equipment is detected for abnormality to obtain an abnormality detection result; wherein, the status analysis includes one or more of data timing analysis, multi-dimensional data comparison and historical data comparison.
[0050] In an embodiment of the present invention, the monitoring and analysis module performs status analysis on signal equipment in the rail transit signal system based on fused data to determine the status of the signal equipment. Specifically, this status analysis includes data time series analysis, multi-dimensional data comparison, and historical data comparison. Data time series analysis involves analyzing the time series of signal equipment status changes based on fused data to identify abnormal values during equipment operation. For example, a signal equipment status switching time outside the normal range may indicate a device failure. Multi-dimensional data comparison compares operating data against a preset normal threshold. If the threshold deviates, anomaly detection is triggered. Historical data comparison compares the current operating data of a signal equipment with its historical operating data. If the difference between the current and historical operating data exceeds a preset difference threshold, the signal equipment is marked as potentially abnormal. Furthermore, if the signal equipment status is abnormal, anomaly detection is performed on the signal equipment to obtain an anomaly detection result. Anomaly detection includes fault location and fault type identification. When a signal equipment failure or anomaly is detected, an alarm is generated based on the anomaly detection result.
[0051] The technical solution of this embodiment includes a BIM model building module for building a BIM three-dimensional model of the rail transit signal system based on the system's equipment information; a three-dimensional data simulation module for acquiring three-dimensional data of the rail transit signal system and its environment, and generating a virtual environment based on the BIM model data and the three-dimensional data; a physical simulation of the rail transit signal system in the virtual environment, and obtaining physical simulation results of the rail transit signal system under different environmental conditions; a data simulation platform for acquiring real-time operational data of the rail transit signal system, performing digital twin simulation based on the operational data, model data, and physical simulation data, and obtaining a digital twin model of the rail transit signal system; and performing intelligent analysis based on the digital twin model to obtain analysis results; and a user interface module for displaying the BIM three-dimensional model, physical simulation results, and analysis results. This system can achieve a panoramic display of the rail transit signal system at different stages. Through transparent management and intelligent analysis of real-time data, it helps to extend the life of the rail transit signal system, reduce operational risks, and effectively improve the operational efficiency and reliability of the rail transit signal system.
