[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The following combination Figure 1-Figure 3 Specific embodiments of the present invention are described.

[0039] Figure 1 This is a flow chart of the real-time modeling method for railway signal engineering provided by the present invention, such as Figure 1 As shown, the method includes the following steps.

[0040] Step 101: Determine the station area attribute, refined station area attribute, and work site category attribute of the target object based on the name and / or model of the target object; wherein the station area attribute is used to indicate the station area location to which the target object belongs; the refined station area attribute is used to indicate whether the target object is located indoors or outdoors; and the work site category attribute is used to indicate the physical entity category to which the target object belongs.

[0041] Among them, the target object refers to the engineering object in the railway signal control system that is to be planned, under construction, or has been completed and is in operation and maintenance. It can be a railway signal tower, base station, or specific equipment such as signal lights, video control boxes, etc.

[0042] The station area attribute is used to indicate the station area location to which the target object belongs, such as station A, station B, relay station C, relay station D, etc. It is mainly divided into two categories, namely stations and relay stations. The station area attribute in this application is a first-level attribute.

[0043] The refined station area attribute is used to indicate whether the target object is located indoors or outdoors. In this application, the refined station area attribute is a secondary attribute.

[0044] The work site category attribute is used to indicate the physical entity category to which the target object belongs, that is, a specific equipment category. In this application, the work site category attribute is a third-level attribute.

[0045] Optionally, the third-level attributes also include the specific visible minimum construction unit (also called work point) to which the target object belongs. Each work point can be connected to a corresponding virtual model to achieve visual management of the target object.

[0046] In this application, the equipment in the railway signal control system is divided into different levels and categories in advance, mainly including the first level (i.e., station area attributes, indicating whether the equipment is located in a signal tower or a relay station), the second level (i.e., detailed station area attributes, indicating whether the equipment is located indoors or outdoors) and the third level (i.e., work site category attributes, indicating the major category of equipment to which the equipment belongs, such as active transponders, passive transponders, LEUs, etc.). These three levels are stored in an associated manner, i.e., the signal tower and relay station in the first level are divided into indoor and outdoor respectively, and the station is divided into indoor equipment and outdoor equipment. Among them, the indoor equipment includes preset types of equipment categories, and the outdoor equipment also includes preset types of equipment categories, and so on.

[0047] Specifically, the user first enters the name or model of the device, and also the location or name of the station area, such as Station A or Relay Station B. For example, "Signal Building A - Outdoor LEU1," where LEU stands for Lineside Electronic Unit, automatically extracts keywords from the user-entered name and compares them with a pre-defined device classification table. The processor identifies the name as a ground electronic unit and determines its station area attribute as Signal Building A, further refining the station area attribute to outdoor.

[0048] Step 102: construct a geometric model of the target object.

[0049] Specifically, geometric models of target objects such as signal machines and relay stations are constructed using Bentley OpenRail or Revit. Bentley OpenRail is a comprehensive software solution developed specifically for railway engineering design, construction, operations, and maintenance. It provides powerful 3D modeling tools, enabling engineers and designers to create detailed 3D models of railway tracks, bridges, tunnels, signal systems, and other railway infrastructure. Revit is a building information modeling software that allows users to quickly generate complex building geometries through its intuitive interface and adjust components and systems within the model through parametric design capabilities.

[0050] Step 103 : Mapping the target object into a pre-built BIM model based on the geometric model of the target object and the station area attributes, the refined station area attributes, and the work site category attributes.

[0051] Specifically, the geometric model of the target object is integrated into the building information model (i.e., BIM model) of the railway signal control system. The target object is mapped to the appropriate position in the system model according to its station area attributes, refined station area attributes, and work site category attributes, and the BIM model is output to the display for user browsing.

[0052] Step 104: Acquire real-time status data of the target object.

[0053] Among them, real-time status data refers to the current status of the device, such as the red, yellow, and green signal status of the traffic light, device voltage, current and other information.

[0054] Step 105: Update the pre-built BIM model according to the real-time status data to obtain a real-time virtual model of the target object.

[0055] Specifically, the pre-built BIM model is updated using real-time status data, or the pre-built BIM model is connected to the digital twin platform to obtain a real-time virtual model of the target object.

[0056] The above embodiment determines the station area attribute, refined station area attribute, and work point category attribute of the target object according to the name and / or model of the target object; wherein the station area attribute is used to indicate the station area location to which the target object belongs; the refined station area attribute is used to indicate whether the target object is located indoors or outdoors; and the work point category attribute is used to indicate the physical entity category to which the target object belongs; a geometric model of the target object is constructed; based on the geometric model of the target object and the station area attribute, the refined station area attribute, and the work point category attribute, the target object is mapped to a pre-constructed BIM model; real-time status data of the target object is obtained; and the pre-constructed BIM model is updated according to the real-time status data to obtain a real-time virtual model of the target object. This method divides the complex railway signal control system into different categories according to the three-level attributes. The three-level attributes are set during modeling, which unifies the equipment attributes for engineers from different departments, facilitates the unified and efficient management of railway communication infrastructure, and realizes visual modeling of the railway signal control system.

[0057] In one embodiment, the real-time status data includes positioning data, and the step 105 includes: calibrating the mapping points of the target object in the pre-built BIM model according to the positioning data to obtain a real-time virtual model of the target object.

[0058] Specifically, a dual-mode positioning module is installed on the physical device corresponding to the target object, or a lidar scanner (scanning frequency 20Hz) is deployed at key trackside nodes to obtain the GPS position coordinates or 3D point cloud coordinates (accuracy ±2mm) of the target object. This positioning data is differentially corrected, converting the GPS position coordinates into coordinates in the railway engineering coordinate system. The ICP algorithm (Iterative Closest Point) is used to align the 3D point cloud coordinates with the pre-set geometry in the BIM model. A device coordinate system binding relationship is established in the BIM model. The positioning data stream is received in real time, and multi-source coordinates are fused using weighted least squares to improve the coordinate accuracy of the target object in the BIM model. If the device deforms, the deformation is detected (e.g., a displacement of ±15mm), triggering a parameter update in the BIM model.

[0059] The above embodiment provides a reliable data basis for constructing the accurate position of the target object in the system model.

[0060] In one embodiment, after step 105, the method further includes: calibrating multiple objects including the target object in the pre-built BIM model using a timestamp alignment technology to obtain a real-time virtual model of the target object.

[0061] Specifically, when the target object is running in the system, a timestamp mark is collected. For example, sensor data (such as displacement, current sensors, etc.) is sampled at a fixed frequency (such as 100 times per second), and a PTP (Precision Time Protocol) synchronization timestamp is attached to each data packet. Atomic clocks are deployed in the railway dispatching center, or the time of the Beidou positioning system is used as the time reference for the entire network. Based on this time reference and the above-mentioned PTP synchronization timestamp, the transmission delay of the data packet from the sensor to the server is measured. According to the transmission delay, reverse delay compensation is performed on the real-time virtual model, the timestamp is calibrated, and the real-time time of the target object is displayed in the BIM model.

[0062] The above embodiment improves the real-time accuracy of the real-time virtual model of the target object by calibrating the time in real time.

[0063] In one embodiment, the method further includes: acquiring current environmental parameters of the target object; and predicting a real-time virtual model of the target object based on the current environmental parameters and the real-time status data to obtain a failure probability of the target object.

[0064] Specifically, the current environmental parameters and the real-time status data are input into a pre-built fault prediction model to obtain the failure probability of the target object output by the pre-built fault prediction model.

[0065] To elaborate, all fault records of the same type of equipment (such as signal lights) in the past five years are extracted from the railway maintenance database, including: fault type (such as circuit board damage), time of failure, maintenance measures (such as replacement part model, maintenance time), and current environmental parameters. Sensors are deployed at the equipment site to collect real-time data: temperature and humidity, vibration sensors, salt spray concentration detectors (for coastal lines, to detect the concentration of corrosive particulate matter), and real-time equipment status data, including current values, voltage fluctuations, etc. The real-time status data and current environmental parameters of the equipment in the past 24 hours are input into the LSTM neural network to obtain the probability of failure in the next 24 hours output by the model. The LSTM neural network is trained using the fault records of the same type of equipment (including historical environmental parameter data and historical status data as well as the corresponding true fault labels).

[0066] The above embodiment improves the practicability of the model and enhances the monitoring and management level of the railway signal control system by predicting the failure probability of the target object.

[0067] In one embodiment, the method further includes: performing 3D rendering on the real-time virtual model of the target object according to the real-time status data, and displaying the 3D rendered real-time virtual model.

[0068] Specifically, the 3D rendered real-time virtual model is displayed on a display device through 3D rendering, thereby improving the visualization effect of the model.
