[0022] Figure 3 It is a schematic structural diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] The following will be combined with Figures 1 - 3 Describe the specific embodiments of the present invention.

[0025] Figure 1 is a schematic flow chart of the real-time modeling method for railway signal engineering provided by the present invention. As Figure 1 shown, the method includes the following steps.

[0026] Step 101: Determine 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 represent the station area position where the target object belongs; the refined station area attribute is used to represent whether the target object is located indoors or outdoors; the work point category attribute is used to represent the physical entity category to which the target object belongs.

[0027] Among them, the target object refers to an engineering object to be planned, under construction, or already built and in operation and maintenance in the railway signal control system, which can be a railway signal building, a base station, or a specific device such as a signal lamp, a video control box, etc.

[0028] The station area attribute is used to represent the station area position where the target object belongs, such as Station A, Station B, Relay Station C, Relay Station D, etc., which are mainly divided into two categories, namely stations and relay stations. The station area attribute in this application is a first-level attribute.

[0029] The refined station area attribute is used to represent whether the target object is located indoors or outdoors. In this application, the refined station area attribute is a second-level attribute.

[0030] The work point category attribute is used to represent the physical entity category to which the target object belongs, that is, the specific major category of the device. In this application, the work point category attribute is a third-level attribute.

[0031] Optionally, the third-level attribute also includes the specific visible minimum construction unit (also called a work point) to which the target object belongs. Each work point can be connected with a corresponding virtual model to realize the visual management of the target object.

[0032] In this application, the devices in the railway signal control system are classified into different levels and categories in advance, mainly including the first level (i.e., the station area attribute, indicating whether the device is located in a signal building or a relay station), the second level (i.e., the refined station area attribute, indicating whether the device is located indoors or outdoors), and the third level (i.e., the work point category attribute, indicating the major category of the device to which the device belongs, such as active balises, passive balises, LEUs, etc.). These three levels are stored associatively, that is, the signal buildings and relay stations in the first level are respectively divided into indoor and outdoor, the stations are divided into indoor devices and outdoor devices, where the indoor devices contain a preset type of device major category, and the outdoor devices also contain a preset type of device major category, and so on.

[0033] Specifically, the user first inputs the name or model number of the device, and also needs to input the location or name of the station area to which it belongs, such as Station A or Relay Station B. For example, "A Signal Building - Outdoor LEU1", where LEU represents Lineside Electronic Unit, the ground electronic unit. The processor automatically extracts keywords based on the name input by the user and compares them with the pre - established device classification table to identify that the name represents a ground electronic unit, determine its station area attribute as A Signal Building, and refine the station area attribute as outdoor.

[0034] Step 102, construct the geometric model of the target object.

[0035] Specifically, use Bentley OpenRail or Revit to construct the geometric models of target objects such as signal lights and relay stations. Among them, Bentley OpenRail is an integrated software solution developed specifically for the design, construction, operation, and maintenance of railway projects, which can provide powerful 3D modeling tools, enabling engineers and designers to create 3D models of detailed railway tracks, bridges, tunnels, signal systems, and other railway infrastructure. Revit is a building information modeling software. Users can quickly generate complex building geometries through its intuitive interface and adjust components and systems in the model through parametric design functions.

[0036] Step 103, based on the geometric model of the target object, the station area attribute, the refined station area attribute, and the work point category attribute, map the target object into the pre - constructed BIM model.

[0037] Specifically, integrate the geometric model of the above - mentioned target object into the building information model (i.e., BIM model) of the railway signal control system, map the target object to the appropriate position in the system model according to its station area attribute, refined station area attribute, and work point category attribute, and output this BIM model to the monitor for the user to view.

[0038] Step 104, obtain the real - time status data of the target object.

[0039] Among them, the real - time status data refers to the current state of the device, such as the red, yellow, and green color signal states of the signal light, device voltage, current, and other information.

[0040] Step 105, update the pre - constructed BIM model according to the real - time status data to obtain the real - time virtual model of the target object.

[0041] Specifically, use the real - time status data to update the pre - constructed BIM model. Or, connect the pre - constructed BIM model to the digital twin platform to obtain the real - time virtual model of the above - mentioned target object.

[0042] In the above embodiments, the station area attribute, the refined station area attribute, and the work point category attribute of the target object are determined according to the name and / or model number of the target object; wherein, the station area attribute is used to represent the station area location to which the target object belongs; the refined station area attribute is used to represent whether the target object is located indoors or outdoors; the work point category attribute is used to represent 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, the station area attribute, the refined station area attribute, and the work point category attribute, the target object is mapped into 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 classifies the complex railway signal control system into different categories according to three-level attributes, sets the three-level attributes during modeling, unifies the device attributes for engineers in different departments, is conducive to realizing the unified and efficient management of railway communication infrastructure, and realizes the visual modeling of the railway signal control system.

[0043] In one embodiment, the above real-time status data includes positioning data, and the above step 105 includes: calibrating the mapping point of the target object in the pre-constructed BIM model according to the positioning data to obtain the real-time virtual model of the target object.

[0044] Specifically, install a dual-mode positioning module on the physical entity device corresponding to the target object, or deploy a lidar scanner (scanning frequency 20Hz) at key nodes beside the track to obtain the GPS position coordinates or three-dimensional point cloud coordinates (accuracy ±2mm) of the target object. Perform differential correction on these positioning data, convert the GPS position coordinates into coordinates in the railway engineering coordinate system, use the ICP algorithm (Iterative Closest Point) to align the three-dimensional point cloud coordinates with the preset geometric body in the BIM model, and establish a device coordinate system binding relationship in the BIM model. Receive the positioning data stream in real time, fuse multi-source coordinates through weighted least squares method to improve the coordinate accuracy of the target object in the BIM model. If the device deforms, detect the device deformation (such as displacement ±15mm) and trigger parameter update in the BIM model.

[0045] The above embodiments provide a reliable data basis for constructing the accurate position of the target object in the system model.

[0046] In one embodiment, after the above step 105, it further includes: using timestamp alignment technology to calibrate multiple objects including the target object in the pre-constructed BIM model to obtain the real-time virtual model of the target object.

[0047] Specifically, when the target object is running in the system, a timestamp mark is collected. For example, sensor data (such as displacement, current sensor, 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. An atomic clock is deployed in the railway dispatching center, or the time of the Beidou positioning system is used as the time reference of the entire network. Based on the time reference and the above-mentioned PTP synchronization timestamp, the transmission delay of the data packet from the sensor to the server is measured, and reverse delay compensation is performed on the real-time virtual model according to the transmission delay. The timestamp is calibrated, and the real-time time of the target object is displayed in the BIM model.

[0048] 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.

[0049] 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.

[0050] Specifically, the current environmental parameters and the real-time status data are input into a pre-built fault prediction model to obtain the fault probability of the target object output by the pre-built fault prediction model.

[0051] 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 fault occurrence, maintenance measures (such as replacement part model, maintenance time), and current environmental parameters are collected. 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 particles), and real-time equipment status data, including current values, voltage fluctuations, etc. The real-time status data of the equipment in the past 24 hours and the current environmental parameters 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).

[0052] The above embodiment improves the practicability of the model and the monitoring and management level of the railway signal control system by predicting the failure probability of the target object.

[0053] In one embodiment, the method further comprises: performing 3D rendering on the real-time virtual model of the target object according to the real-time status data, and displaying the real-time virtual model after 3D rendering.

[0054] Specifically, the 3D-rendered real-time virtual model is displayed on a display device through 3D rendering, improving the visualization effect of the model.
