Description

Technical Field

[0001] The present invention relates to a structural health monitoring and intelligent operation and maintenance management system for a railway passenger station, and in particular to a structural health monitoring and intelligent operation and maintenance platform for a railway passenger station building. Background Art

[0002] At present, the structural health monitoring systems of railway passenger stations mostly focus on the monitoring of a single data source, usually only focusing on certain physical parameters (such as strain, temperature and humidity, vibration, etc.) or local areas.

[0003] Patent document CN201911124048.2 discloses a PHM application system, method and storage medium suitable for high-speed railways, which includes: a data acquisition module for obtaining detection and monitoring data of key equipment and facilities of high-speed railways; a data processing module for format preprocessing, feature layer data fusion and feature extraction processing of equipment and facility data to obtain processed data; a data analysis module for performing status detection analysis, fault diagnosis analysis, health assessment analysis and fault prediction analysis on high-speed railway equipment and facilities based on the processed data to obtain analysis results; a maintenance result generation module for generating fault handling results and health management results for high-speed railway equipment and facilities based on the analysis results. By implementing the present invention, limited detection and monitoring data resources can be concentrated to achieve more accurate fault prediction and health perception, reduce the risks caused by faults during operation, and improve the safety of high-speed railway operations and maintenance efficiency.

[0004] Patent document CN202310431493.3 discloses a digital system and method for the three-dimensional development of rail transit stations. The system includes a facility layer, a data layer, an application service layer, a user layer, and a terminal; the facility layer includes network resources, computing resources, storage resources, cloud deployment, and Internet of Things perception; the data layer is divided into data resources and data management, and the data resource part includes BIM, GIS, planning and design data, construction data, and structural health monitoring data; the data management part collects, cleans, stores, governs, and analyzes data based on the platform functional requirements; the application service layer includes a basic module, a planning module, a design module, a construction module, and an operation and maintenance module; the user layer is the platform users; the terminal is the output terminal of the digital platform for the three-dimensional development of rail transit stations.

[0005] Although these systems can provide basic health data, they have significant deficiencies in the following aspects: First, existing technologies lack a comprehensive assessment of the entire passenger station structure, especially the failure to comprehensively consider the long-term impact of environmental factors, usage loads and other external conditions on structural health. Second, the data collection and analysis functions of most systems are scattered, and they fail to achieve effective integration of different types of data (such as monitoring data, design drawings, construction records, etc.), resulting in information islands and difficulty in achieving real-time monitoring and intelligent analysis. Finally, the fault warning mechanism of existing systems mostly relies on simple threshold settings, lacks intelligent analysis and prediction functions, and cannot identify potential structural problems in a timely and accurate manner, affecting the response speed and prevention effect of faults. Summary of the invention

[0006] The present invention aims to solve several key problems in current technology. First, it is necessary to realize the integration of multi-source data, including structural health data, environmental data, passenger station life cycle information (such as design drawings, construction records, operation and maintenance logs, etc.), and combine these data with spatial information (through BIM and GIS technology) to realize dynamic monitoring and comprehensive evaluation of the entire railway passenger station. Secondly, the fault warning mechanism in the prior art mostly relies on simple threshold alarms and lacks intelligent fault diagnosis and prediction capabilities. The present invention will enhance the intelligent warning capability of the system through intelligent diagnosis and comprehensive evaluation methods to ensure that potential risks can be identified in a timely manner in complex situations. In addition, how to integrate monitoring, equipment management, task scheduling and other functions into a unified platform to simplify the operation process and improve work efficiency is also a technical problem that needs to be solved. The present invention will also realize the automatic arrangement of daily inspections, regular inspections and special inspection tasks through task management and delegation functions, and can generate detailed reports to further improve operation and maintenance efficiency.

[0007] In order to achieve the above-mentioned object, the present invention provides a structural health monitoring and intelligent operation and maintenance platform for railway passenger station buildings, comprising:

[0008] Railway passenger station information manager module, which provides comprehensive passenger station structural health monitoring through visual display and data integration;

[0009] Intelligent diagnosis system, which collects statistics and provides early warnings for emergency events through online diagnosis and comprehensive evaluation;

[0010] The event processing system can push warning information to the platform administrator in a timely manner when a threshold event is triggered to ensure that the fault is handled in a timely manner;

[0011] The maintenance system is responsible for the management and entrustment of daily operation and maintenance tasks, automatically arranges daily inspections, regular inspections and special inspection tasks, and records the execution status of each task

[0012] Reporting system, customized to generate reports on structural health status, maintenance progress, etc.

[0013] Furthermore, the railway passenger station information manager module includes a three-dimensional visualization module, a sensor data integration module and a high-speed railway station information viewing module.

[0014] Furthermore, the three-dimensional visualization module builds a three-dimensional digital base for the passenger station structure based on BIM+GIS technology; the sensor data integration module combines information collected by various sensors and sensor hardware information to achieve real-time monitoring; the high-speed railway station information viewing module can view the entire life cycle information of the high-speed railway station.

[0015] Furthermore, the information collected by the sensor includes information such as strain, vibration, temperature or humidity; the sensor hardware information includes information such as sensor layout location or component location.

[0016] Furthermore, events are analyzed and warned through online diagnosis and comprehensive evaluation as follows: The system first collects relevant data of the structure or equipment through sensors, and the collected data is transmitted to the online intelligent diagnosis module for real-time analysis. During the online diagnosis process, the system will identify and eliminate abnormal data to ensure the accuracy of the analysis. No warning evaluation will be performed on abnormal data, and normal data will be divided into two categories according to whether the data needs to be calculated and evaluated. One category is data that needs to be calculated and evaluated, and structural safety evaluation, component sub-unit safety evaluation and overall structural safety evaluation of the station building will be performed in turn, and finally a warning event will be formed; the other category is data that does not need to be calculated and evaluated. If the threshold is exceeded, a warning will be directly triggered, thus forming a warning event; the formed warning event will be pushed to the large screen for display and to the administrator for timely processing and response to possible safety issues.

[0017] Furthermore, when a threshold event is triggered, early warning information can be pushed to the platform administrator in a timely manner to ensure that the fault is handled in a timely manner. Specifically, the early warning event is first pushed to the platform administrator. After receiving it, the administrator initiates analysis and evaluation, and then enters the on-site inspection and processing link to determine whether the early warning has been resolved. If it has been resolved, the early warning problem is resolved; if not, it enters the expert evaluation link until the early warning problem is finally resolved.

[0018] Furthermore, the expert evaluation process includes two methods: analysis and judgment by on-site personnel and analysis and judgment by experts, which ensure accurate judgment and handling of incidents through collaborative work.

[0019] Furthermore, the maintenance system also includes real-time recording of the execution status of each task and generating a task report to facilitate subsequent tracking and review. At the same time, based on historical data and structural health assessment results, the arrangement of maintenance tasks is optimized to ensure the rational use of resources.

[0020] Furthermore, the report includes one or more of a maintenance report, an event report, and a periodic report.

[0021] Furthermore, the report includes visualizations such as charts and data statistics to help managers intuitively understand the health status of the structure.

[0022] The beneficial effects of the present invention are as follows:

[0023] The present invention integrates multi-source data such as structural health, environment, and the entire life cycle of passenger stations, and combines BIM and GIS technology to achieve dynamic monitoring and comprehensive evaluation of railway passenger stations, overcome the defects of incomplete evaluation of passenger station structures in existing technologies, provide a more scientific basis for operation and maintenance, and significantly improve the efficiency and accuracy of passenger station structural health management. Through real-time monitoring and intelligent analysis, the system can identify potential faults in advance and reduce the occurrence of sudden problems. Integrate monitoring, equipment management, task scheduling and other functions into one, simplify the operation process and improve work efficiency. The management and maintenance system automatically arranges tasks and optimizes plans to ensure orderly maintenance; the event handling system forms a closed-loop mechanism to ensure timely handling of faults and improve the overall operation and maintenance management efficiency. Intelligent diagnosis and early warning mechanisms help operation and maintenance personnel to detect problems and respond in time, thereby extending the service life of the structure and reducing maintenance costs. Automated task management and report generation functions improve operation and maintenance efficiency, making the operation and maintenance of passenger stations more efficient and orderly.

[0036] Figure 1 This is the overall architecture diagram of the railway station structural health monitoring, including:

[0037] To achieve the above purpose, the present invention adopts the following technical solutions:

[0038] 1Railway passenger station information manager module

[0039] The railway passenger station information manager module includes a 3D visualization module, a sensor data integration module, and a high-speed railway station information viewing module. The railway passenger station information manager module is based on BIM and GIS technology, and provides comprehensive passenger station structural health monitoring through visualization and data integration. The module can display the 3D panoramic model of the passenger station in real time, and combine spatial data and monitoring data to form a dynamic structural health monitoring data observation and display platform. The module also supports viewing the entire life cycle information from design to construction, operation to maintenance, including design drawings, construction records, operation and maintenance logs, and current health status.

[0040] Features

[0041] (1) 3D visualization module for 3D panoramic display: Based on BIM+GIS technology, a 3D digital base for the passenger station structure is built, and users can view the 3D information of the structure in multiple dimensions and levels.

[0042] (2) Sensor data integration module integrates sensor data: various sensor data (such as strain, vibration, temperature and humidity, etc.) are combined with spatial information (such as sensor layout location and component location) to achieve real-time monitoring.

[0043] (3) The high-speed railway station information viewing module manages information throughout the entire life cycle: it can view the complete historical records of the passenger station from design to construction, operation and maintenance, providing sufficient data support for management decisions.

[0044] Figure 2 This is a schematic diagram of the information manager module. On the left: the three-dimensional panoramic map display area of ​​the railway passenger station, which includes functions such as the station building diagram display, the station structure diagram display, and the sensor layout display, which can intuitively present the three-dimensional panoramic information of the railway passenger station. On the right: the top is a statistical chart of the online rate of various sensors, which can show the online status of the sensors; the bottom is a summary of the monitoring days of all monitored railway passenger stations, and you can also view the detailed information of each passenger station and the detailed information of the sensors. The entire interface is divided into different areas to fully display the relevant information of the railway passenger station, including the three-dimensional panorama, sensor status, passenger station monitoring days, etc., providing users with an information-rich, easy-to-view and analyze platform.

[0045] 2 Intelligent Diagnosis System

[0046] Figure 3It is a flowchart of the intelligent diagnosis system, which shows a process of structural health monitoring and early warning. Sensor data collection: The system first collects relevant data of the structure or equipment through sensors. Online intelligent diagnosis: The collected data is transmitted to the online intelligent diagnosis module for real-time analysis. Abnormal data removal: During the online diagnosis process, the system will identify and remove abnormal data to ensure the accuracy of the analysis. Removal without early warning evaluation: The removed abnormal data will not enter the early warning evaluation process to avoid false alarms. Normal data is divided into two categories according to whether it is necessary to calculate the evaluation data: one category is the need to calculate the evaluation data, which will be carried out in turn for structural safety assessment, component subunit safety assessment and station building overall structural safety assessment, and finally form an early warning event; the other category is the need to calculate the evaluation data, and if it exceeds the threshold, the early warning will be directly triggered. The formed early warning event will be pushed to the large screen for display and pushed to the administrator to promptly handle and respond to possible safety issues. The entire process aims to achieve real-time monitoring and early warning of structural safety and ensure the safe operation of related facilities. This process ensures the accuracy and timeliness of the data, and also improves the efficiency of structural health monitoring and the reliability of early warning. Through the intelligent diagnostic system, the status of structures or equipment can be effectively monitored and managed to prevent potential safety problems.

[0047] The intelligent diagnosis system uses big data analysis and machine learning algorithms to analyze events that trigger thresholds through online diagnosis and comprehensive evaluation. The system can eliminate abnormal and erroneous data, accurately determine the health status of the structure, and display structural safety information. The system can intelligently evaluate structural health in complex environments, count and handle emergency events (such as special weather, emergencies, natural disasters, etc.).

[0048] Features

[0049] (1) Intelligent fault diagnosis: Through machine learning algorithms, the system can identify potential structural faults from a large amount of monitoring data and perform diagnosis and warning in advance.

[0050] (2) Abnormal data elimination: Using data cleaning technology, the system can automatically eliminate abnormal or erroneous data and improve the accuracy of analysis results.

[0051] (3) Emergency response and event statistics: The system can count various events (such as special weather, natural disasters, construction events, etc.) in real time and generate emergency response plans.

[0052] (4) Structural safety assessment: The sensor monitoring data is used to intelligently assess the structural health status of the entire passenger station structure, and whether the health risk exceeds the threshold is displayed based on the safety of the structure, helping operation and maintenance personnel to make timely decisions.

[0053] 3Event Handling System

[0054] Figure 4 This is a schematic diagram of the event processing system. First, the warning event is pushed to the platform administrator, who initiates analysis and evaluation after receiving it. Then, the on-site inspection and processing phase is entered to determine whether the warning has been resolved. If it has been resolved, the warning problem has been resolved; if not, the expert evaluation phase is entered until the warning problem is finally resolved. The entire process forms a closed-loop processing mechanism from warning event push, analysis and evaluation, on-site processing to expert intervention, ensuring that the warning problem can be properly handled and resolved.

[0055] The event handling system can automatically report and issue an early warning when a fault or abnormal event is detected. The system initiates analysis and evaluation through the platform administrator, enters the early warning management process, and finally conducts fault analysis and closed-loop early warning process through on-site personnel or experts. This module supports real-time display of fault information and emergency handling status to ensure timely response and resolution of events.

[0056] Features

[0057] (1) Warning information push: When a threshold event is triggered, the system can promptly push warning information to the platform administrator to ensure that the fault is handled in a timely manner.

[0058] (2) Event management process: Through analysis and evaluation by the platform administrator, events will enter the early warning management process, providing an early warning closed-loop mechanism to ensure that each event is properly handled.

[0059] (3) Multi-mode expert analysis: The system supports both on-site personnel and expert analysis and judgment, ensuring accurate judgment and handling of events through collaborative work.

[0060] 4. Pipe maintenance system

[0061] The maintenance system is responsible for the management and delegation of daily operation and maintenance tasks. The system can automatically arrange daily inspections, regular inspections and special inspection tasks, and record the execution of each task. The system improves operation and maintenance efficiency through automated task management and ensures that maintenance work is carried out as planned.

[0062] Features

[0063] (1) Automatic task scheduling: The system automatically schedules patrol tasks, inspection tasks and special tasks according to preset plans.

[0064] (2) Task execution record: The execution status of each task will be recorded in real time and a task report will be generated to facilitate subsequent tracking and review.

[0065] (3) Inspection task management: Supports various types of task arrangements such as regular inspections and emergency inspections to ensure that the structural health of the passenger station is always under monitoring.

[0066] (4) Maintenance plan optimization: Based on historical data and structural health assessment results, the system can optimize the arrangement of maintenance tasks and ensure the rational use of resources.

[0067] 5. Reporting System

[0068] The reporting system provides a comprehensive and flexible report generation platform for operation and maintenance personnel, aiming to help users efficiently manage and analyze various types of operation and maintenance data. Through this system, users can generate various types of reports according to specific needs, including but not limited to maintenance reports, event reports and regular reports. These reports cover key information such as structural health status, equipment operation status, maintenance records, etc., providing detailed data support for operation and maintenance decisions.

[0069] Features

[0070] (1) Generate multiple reports

[0071] Maintenance report: The system can generate a detailed maintenance report based on the daily maintenance and maintenance records of the equipment. The report will display the equipment's maintenance cycle, maintenance content, maintenance personnel and other information, as well as problems found during the maintenance process and treatment measures. Through the maintenance report, managers can clearly understand the maintenance status of the equipment, discover potential risks in a timely manner, and ensure the stable operation of the equipment.

[0072] Event report: When the system detects equipment failure or other abnormal events, it can quickly generate an event report. The report will record in detail the time, location, type, cause, scope of impact, and emergency measures taken. This helps managers quickly understand the situation of the event and conduct effective emergency response and subsequent analysis.

[0073] Regular reports: The system supports the generation of regular reports, such as weekly, monthly, and quarterly reports. Regular reports will summarize the operation and maintenance data within a certain period, including equipment operation status, fault statistics, maintenance progress, etc. Through regular reports, managers can fully understand the overall situation of operation and maintenance work, evaluate the operation and maintenance effects, and provide a basis for formulating the next work plan.

[0074] (2) Report customization

[0075] Content customization: Users can flexibly select content modules to be included in the report according to actual needs. For example, when generating a device health status report, you can select modules that include the device's operating parameters, historical fault records, and repair and maintenance status; when generating a maintenance progress report, you can select modules that include maintenance plans, completed maintenance tasks, unfinished tasks and their reasons. In this way, the report content can accurately meet the user's management needs and avoid information redundancy or omissions.

[0076] Format customization: The system supports users to customize the format and layout of reports. Users can set the report title, font, color, table style, etc. according to their preferences and management habits. For example, different title styles can be set for different types of reports to highlight their importance; the column width and row height of the table can be adjusted to make the data display clearer and easier to read. In addition, you can also add customized charts, pictures and other elements to enrich the visual effects of the report and make it more attractive.

[0077] (3) Report export function

[0078] Export in multiple formats: The generated reports can be exported in multiple standard formats, such as PDF, Excel, etc. Reports in PDF format have good compatibility and security, are suitable for archiving and sharing, and will not cause content confusion due to formatting issues; reports in Excel format are convenient for further analysis and processing of data, such as data sorting, filtering, calculation, etc. Users can choose the appropriate export format according to actual needs to facilitate subsequent work.

[0079] Convenient export operation: The system provides an easy-to-use export function. Users only need to click the "Export" button to quickly export the report to the required format. During the export process, the system will automatically layout and adjust the report content according to the set format to ensure that the exported report is consistent with the report content displayed in the system, avoiding errors caused by improper export operations.

[0080] (4) Intelligent data statistics

[0081] Chart display: The report contains a variety of charts, such as bar charts, line charts, pie charts, etc., which are used to intuitively display the changing trends and distribution of data. For example, in the equipment failure statistics report, the number of failures of different equipment can be displayed through a bar chart, and the trend of equipment failure rate over time can be displayed through a line chart; in the maintenance progress report, the ratio of completed tasks to unfinished tasks can be displayed through a pie chart. The use of charts makes data more intuitive and easy to understand, helping managers quickly grasp key information.

[0082] Data statistics and analysis: The system can perform intelligent statistics and analysis on operation and maintenance data, and generate various statistical indicators and analysis results. For example, it can calculate indicators such as the mean time between failures (MTBF) and mean time to repair (MTTR) of equipment to evaluate the reliability and maintenance efficiency of equipment; it can perform statistical analysis on maintenance costs to identify the key links of cost control and provide a basis for reducing costs. Through intelligent data statistics, managers can have a deeper understanding of the current status and existing problems of operation and maintenance work, and provide strong support for formulating improvement measures.

[0083] In short, the reporting system provides a powerful data management and analysis tool for operation and maintenance personnel through functions such as multiple report generation, flexible report customization, convenient report export, and intelligent data statistics. It can not only improve the efficiency and quality of operation and maintenance work, but also help managers better understand the operation and maintenance situation, make scientific decisions, and ensure the stable operation of equipment and efficient operation of the system.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
