Description

Technical Field

[0001] The present invention relates to railway management and control technology, and in particular to a railway construction management deduction and simulation method and system. Background Art

[0002] The existing railway construction management system is fragmented and coordination is difficult. The construction management system, skylight repair management, train dispatching and other platforms operate independently, and the data are not interconnected. For example, the power outage status of the contact network cannot be synchronized to the train dispatching system in real time, which may cause electric locomotives to mistakenly enter the power outage construction area; the construction blockade area needs to be manually checked repeatedly between the paper ledger and the interlocking system, which is prone to missed detection and wrong detection. This fragmented management leads to lengthy construction plan approval processes, construction plan conflicts in the construction organization process, difficulties in construction route deduction, and problems such as delayed disclosure and delayed safety risk warnings. Summary of the Invention

[0003] The purpose of the present invention is to provide a railway construction management simulation method to solve the problems of construction plan conflicts, construction route simulation difficulties and untimely disclosure in the construction organization process.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a railway construction management simulation method, which automatically obtains the construction plan issued by the railway safety production dispatching and command center system through the interface with the railway safety production dispatching and command center system, parses the construction plan to automatically extract the construction scope and responsible unit information, generates structured construction meeting records in combination with predefined items, issues the construction list of the site according to the site parameters associated with the structured construction meeting records, builds a formal plan overview and a construction simulation map, maps the construction section to the plan overview according to the construction list for visual presentation, and simulates the construction section, simulates the train route, personnel path and equipment trajectory in the construction process, detects construction conflicts in real time and triggers safety alarms.

[0005] Furthermore, the following process is performed to obtain the construction plan: a communication connection is established with the railway production safety dispatching and command center system, and regular synchronization is performed with the railway production safety dispatching and command center system to obtain the construction plan, wherein the construction plan includes the construction time, all construction areas in the station, and the equipment in the station occupied by each construction area during the construction process.

[0006] Furthermore, predefined items include common part issues, road train operation issues, overhead power outage issues, speed limit issues, and road material vehicle loading and unloading, which can be selected from the construction plan based on the selection of corresponding preset items.

[0007] Furthermore, after the visual railway map is built and the construction list of the site is entered, the construction process is simulated and time conflicts, resource conflicts and safety distance conflicts are automatically detected. The conflict detection results are displayed graphically on the visual railway map, including the conflict location, type and impact range, so that users can quickly identify and resolve conflicts.

[0008] Furthermore, a dynamic rule base associated with the construction type is established. The rule base predefines the train route restrictions, personnel safety areas and equipment adaptation types for track construction, contact network construction and signal construction. The corresponding restrictions are activated according to the current construction type, and the dispatchable train types, personnel path planning range and equipment on-track authority are dynamically constrained in the simulation interface. When the simulation operation violates any constraint in the rule base, a safety alarm is automatically triggered. The compliance of all constraints is verified through iterative simulation, and a maintenance equipment dispatch plan and path binding instructions that match the construction plan are output.

[0009] Furthermore, the construction of the formal plan overview map and construction simulation map is based on the station yard map or CIPS system base map as the simulation base map. The base map data is extracted to form an SVG format map or manually drawn according to the map site location.

[0010] A simulation system for executing the above-mentioned railway construction management simulation method, comprising a construction control platform, a construction process platform, and a construction plan platform;

[0011] The construction management and control platform is used to connect with the railway production safety dispatching command center system to achieve automatic acquisition and structured analysis of construction plans;

[0012] The construction process platform includes a meeting management module for generating structured meeting records based on a predefined item point library and associating them with construction simulation constraints; a construction cross-section diagram module for generating a visualization chart of the entire construction timeline and linking it with simulation interface data; a site configuration module for managing site parameters and equipment occupancy relationships involved in the construction plan; a visualization construction module for drawing station construction simulation diagrams and formal plan overview diagrams; and a construction simulation module for dynamically simulating train routes, personnel paths, and equipment trajectories.

[0013] Furthermore, the construction simulation map module dynamically superimposes the construction progress layer, equipment occupancy layer and conflict marking layer. The conflict marking layer dynamically marks the conflict location and impact range with highlighted color blocks based on the detection results of safety distance conflict and resource limit conflict.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The construction process control system can identify relevant information in the construction plan and provide a multi-station or single-station visual display on the official plan overview and construction simulation diagram. Through functions such as animated simulation of route operation, automatic simulation of fixed personnel routes, and simulation of large equipment routes, we can intuitively understand each link and potential risks in the construction process. At the same time, the construction process control system also has an automatic alarm reminder function. For example, in the event of an electric locomotive mistakenly running into a power outage area or a conflict in the blockade area, it can promptly issue an alarm and take appropriate safety measures. The construction simulation diagram can demonstrate the revelation and unrolling of the control console during construction. This function effectively solves safety issues such as construction plan conflicts, difficulties in construction route simulation, and untimely revelation and unrolling in the construction organization process, thereby improving the accuracy and timeliness of risk warnings. The construction cross-section diagram can intuitively reflect all construction information and construction time within the section, allowing workshop (station) and section management personnel to intuitively grasp the construction information of the entire section.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0026] like Figures 1 to 7 As shown, the present invention provides a railway construction management simulation method and system thereof, including a construction control platform, a construction process platform and a construction plan platform;

[0027] The construction management and control platform is used to connect with the railway production safety dispatching command center system to achieve automatic acquisition and structured analysis of construction plans;

[0028] The construction process platform includes a meeting management module for generating structured meeting records based on a predefined item point library and associating them with construction simulation constraints, a construction cross-section diagram module for generating a visualization chart of the entire construction timeline and linking it with simulation interface data, a site configuration module for managing site parameters and equipment occupancy relationships involved in the construction plan, a visualization construction module for drawing station construction simulation diagrams and formal plan overviews, and a construction simulation module for dynamically simulating train routes, personnel paths, and equipment trajectories. The system adopts a B / S architecture model. The main technical framework uses NetCore+Abp+MySql, the middleware layer mainly uses middleware such as Nginx and Redis, and the front end uses mainstream market technologies and framework languages ​​such as Vue3, Http, SCSS, and TypeScript for system development. At the same time, distributed processing methods such as Nginx are used to assist in big data analysis. The entire system adopts a containerized deployment model.

[0029] The following is an introduction to the main core technologies of the present invention, which mainly include three parts:

[0030] The core technical aspects of this railway construction management simulation method and system revolve around automated data processing, visual simulation, and intelligent conflict detection. The system automatically acquires and analyzes construction plans by establishing an interface with the railway safety production dispatching and command center system, extracting key parameters such as construction time, area, and equipment occupancy. It then automatically generates structured construction meeting records based on a predefined database of items (e.g., catenary outages, speed limits, and road material loading and unloading). This process transforms unstructured data into actionable construction and maintenance checklists, which in turn trigger the subsequent visualization simulation process. The simulation results support the visualization of construction and maintenance plans for multiple stations and between stations, as well as for track and turnout plans within a single station. It also supports the simultaneous visualization of multiple single-station construction plans. The simulation structure support system, based on station yard maps or CIPS system basemaps, creates a visualization interface through SVG format conversion or manual drawing. Construction plans are mapped to formal plan overviews and construction simulation diagrams, creating a digital construction scenario in both time and space.

[0031] 2. In the dynamic deduction link, the system relies on the dynamic rule base associated with the construction type to achieve multi-dimensional constraints. The rule base predefines the train route restrictions, personnel safety areas and equipment adaptation rules for different types of operations such as track construction and contact network construction. For example, when the contact network is out of power, the train dispatching authority of the relevant track area is automatically locked, and the personnel path planning range is limited during signal construction. During the deduction process, the three-dimensional simulation engine calculates the train route, personnel movement trajectory and equipment on-road path in real time, and detects time conflicts (such as overlapping construction periods), resource conflicts (such as the same equipment being occupied by multiple construction parties) and safety distance conflicts (such as insufficient minimum distance between equipment and trains) through the time-space superposition algorithm. The detection results are presented in real time on the visual interface in the form of highlighted blocks, dynamic marks, etc., and the conflict location, type and impact radius are specifically marked to form an intuitive risk warning.

[0032] 3. The system's modules achieve deep collaboration through a data bus. After analyzing the raw data captured by the construction control platform, the meeting management module generates structured meeting records and associates them with construction constraints. Simultaneously, the site configuration module establishes a map of equipment occupancy relationships. The visualization construction module integrates this data with the SVG / CIPS basemap to create an interactive simulation interface. The construction cross-section diagram module simultaneously generates a timeline view that is updated in sync with the 3D simulation process. When the conflict detection system detects a violation, it not only triggers a safety alert but also reversely corrects the risk items in the meeting record and initiates an iterative simulation mode to re-verify the feasibility of the solution. The final output, the maintenance equipment dispatch plan and path binding instructions, are transmitted back to the command center system via an interface, forming a closed-loop management loop. This complete chain, from plan analysis, rule constraints, dynamic simulation, to feedback optimization, realizes digital control of the entire construction management process, significantly improving construction safety and scheduling efficiency.

[0033] The railway construction management simulation method is as follows: through the interface with the railway safety production dispatching command center system, the construction plan issued by the railway safety production dispatching command center system is automatically obtained, the construction plan is automatically extracted from the construction scope and responsible unit information, and structured construction meeting records are generated in combination with predefined items. The construction list of the site is issued according to the site parameters associated with the structured construction meeting records, and a formal plan overview and construction simulation map are built. The construction section is mapped to the plan overview according to the construction list for visual presentation, and the construction section is simulated to simulate the train route, personnel path and equipment trajectory in the construction process, and construction conflicts are detected in real time and safety alarms are triggered; those skilled in the art can understand that by connecting to the railway safety production dispatching command center to realize automatic acquisition and analysis of the construction plan, the original plan data containing information such as construction scope and responsible unit are compared with predefined safety items (such as contact network power outage, speed limit requirements, etc.). The system then uses intelligent matching to generate structured construction meeting records based on the site parameters in the records, and automatically generates specific construction checklists based on the site parameters in the records. A visual simulation platform is then built using railway yard maps or CIPS system base maps, mapping construction sections as highlighted areas on the map. Dynamic simulation technology is used to simulate train routes (such as route adjustments to bypass construction sections), construction personnel activity paths (such as safe passages to avoid track traffic), and construction machinery operation trajectories (such as the limit range of crane arm span). Risks such as temporal and spatial overlap (such as conflicts between maintenance periods and train passage times), equipment occupancy conflicts (such as cross-operation between multiple teams sharing tracks), and insufficient safety distances are detected in real time, triggering audible and visual alarms (such as a flashing prompt indicating "7:30 train at K123+500 conflicts with construction machinery trajectory"). This creates a digital control closed loop for the entire process, from plan introduction to risk prediction. This is equivalent to deploying a "simulation verification first, actual execution later" intelligent insurance mechanism for railway construction.

[0034] The following process is used to obtain the construction plan: establish a communication connection with the railway safety production dispatching and command center system, and regularly synchronize with the railway safety production dispatching and command center system to obtain the construction plan, which includes the maintenance plan, construction time, all construction areas in the station, and the equipment in the station occupied by each construction area during the construction process.

[0035] Predefined items include problems with public areas, road train operation problems, contact network power outage problems, speed limit problems and road material vehicle loading and unloading. They can be selected from the construction plan based on the corresponding preset item points. Those skilled in the art can understand that the predefined item points are matters that are frequently handled at the site. Frequently handled matters are set as predefined items. By checking the predefined items, the keywords of the matters included in the predefined options can be automatically filtered out from the construction plan. The platform packages and organizes these filtered keywords to form construction meeting records that need to be handled by the site. The specific construction plan of the site can be clarified through the construction meeting records.

[0036] After the visual railway map is built and the construction list of the site is entered, the construction process simulation automatically detects time conflicts, resource conflicts and safety distance conflicts. The conflict detection results are displayed graphically on the visual railway map, including the conflict location, type and impact range, so that users can quickly identify and resolve conflicts.

[0037] A dynamic rule base associated with construction types is established. The rule base predefines train route restrictions, personnel safety areas, and equipment adaptation types for track construction, contact network construction, and signal construction. The corresponding restrictions are activated according to the current construction type, and the dispatchable train types, personnel path planning range, and equipment on-track authority are dynamically constrained in the simulation interface. When the simulation operation violates any constraint in the rule base, a safety alarm is automatically triggered. The compliance of all constraints is verified through iterative simulation, and a maintenance equipment dispatch plan and path binding instructions that match the construction plan are output.

[0038] The construction of the formal plan overview map and construction simulation map is based on the station yard map or CIPS system base map as the simulation base map. The base map data is extracted to form an SVG format map or manually drawn according to the map site location.

[0039] In addition to the above-mentioned preferred embodiments, the present invention has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
