Description

Technical Field

[0001] The present invention relates to the technical field of urban infrastructure monitoring, and in particular to an urban regional-level pipe gallery monitoring system based on distributed temperature measurement optical fibers and base stations. Background Art

[0002] Urban underground pipeline corridors, as an important part of modern urban infrastructure, undertake the task of centralized laying and management of various municipal pipelines such as power cables, communication cables, water supply pipelines, and drainage pipelines. They are like the "lifeline" of the city, and their safe and stable operation is directly related to the daily life quality of urban residents and the overall operation efficiency of the city.

[0003] Traditional monitoring methods for pipe corridors mainly rely on manual inspections and fixed-point monitoring equipment. Although manual inspections can visually check the conditions in the pipe corridor, they are often difficult to detect and handle sudden faults in a timely manner due to the limited human resources and the fixed inspection cycle. Although fixed-point monitoring equipment can achieve real-time monitoring of specific locations, due to the limited number and location of monitoring points, there are often large monitoring blind spots, and it is impossible to fully cover all areas inside the pipe corridor. Especially in terms of temperature monitoring, due to the dense pipelines inside the pipe corridor and the complex operating environment, temperature anomalies often indicate potential safety hazards such as fire and leakage. Traditional temperature monitoring equipment, such as thermocouples and thermal resistors, are difficult to meet the needs of real-time temperature monitoring in the pipe corridor due to limited measurement range, slow response speed, and complex installation. In addition, with the expansion of urban scale and the increase in the length of pipe corridors, traditional monitoring methods are also facing increasing challenges in data processing, fault location, and early warning release. How to achieve comprehensive, rapid, and accurate monitoring of temperature anomalies in the pipe corridor has become an important issue that needs to be solved in the current field of urban infrastructure monitoring technology. Summary of the invention

[0031] In order to solve the problems of large monitoring blind spots, inaccurate positioning, and untimely response existing in traditional tunnel monitoring methods, an embodiment of the present invention provides an urban regional tunnel monitoring system based on distributed temperature measuring optical fiber and base station. The system realizes comprehensive and continuous monitoring of the temperature in the urban underground tunnel through distributed temperature measuring optical fiber, and combines the multi-level base station architecture to collect, process and analyze data and locate faults, and uses the monitoring and early warning module to realize the early warning level division and early warning information push.

[0032] Hereinafter, an urban area-level pipeline corridor monitoring system based on distributed temperature measurement optical fiber and base station provided by an embodiment of the present invention will be introduced in detail with reference to the accompanying drawings.

[0033] Figure 1 FIG. 1 shows a schematic diagram of the structure of a city-level pipe gallery monitoring system based on distributed temperature measurement optical fiber and base station provided by an embodiment of the present invention. Figure 1 As shown, the system includes a distributed temperature measurement optical fiber 1, a multi-level base station architecture 2, a monitoring and early warning module 3, a repair guidance feedback module 4 and a user display module 5.

[0034] like Figure 2 As shown, the distributed temperature measurement optical fiber 1 is laid along a preset path inside the urban pipe gallery 12. The distributed temperature measurement optical fiber 1 has the characteristics of high sensitivity and long-distance continuous monitoring, and can sense and transmit the temperature change information along the pipe gallery in real time. In this embodiment, the distributed temperature measurement optical fiber 1 used is a distributed temperature measurement optical fiber based on the Raman scattering principle. This optical fiber can continuously monitor the temperature distribution over a long distance (usually up to tens of kilometers), and has high measurement accuracy and fast response speed.

[0035] It should be understood that when the distributed temperature measurement optical fiber 1 is laid, a reasonable optical fiber laying plan is designed according to the structural characteristics and monitoring requirements of the urban pipe gallery 12. The optical fiber should be laid along the main path of the pipe gallery, such as power cable trenches, communication cable troughs, and around water supply and drainage pipes, to ensure that the key areas inside the pipe gallery can be fully covered. During the laying process, the optical fiber should be firmly fixed to avoid movement in the pipe gallery or damage by external forces.

[0036] like Figure 2 and 3 As shown, the multi-level base station architecture 2 includes a substation layer and a main station layer. Among them, the substation layer: according to the urban area division, multiple substations 22 are set along the urban pipeline corridor 12. The urban pipeline corridor 12 is composed of pipeline corridors 23 crisscrossing in the area. Each substation 22 is connected to the distributed temperature measurement optical fiber 1 in its coverage area, responsible for collecting the temperature data transmitted by the distributed temperature measurement optical fiber 1 in its coverage area, and performing preliminary processing and analysis on the collected temperature data, identifying temperature anomalies, and uploading relevant data to the main station layer; the main station layer: a main station 21 is set, and all substations 22 upload relevant data to the main station 21 by wired or wireless means. The main station 21 is the core of the entire monitoring system and is responsible for data aggregation, comprehensive analysis and fault location.

[0037] It should be understood that when setting up each substation 22 in the substation layer, substations 22 are set up at important nodes or areas along the pipeline corridor. Substations 22 should have data processing and preliminary analysis capabilities, be able to identify temperature anomalies, and upload relevant data to the main station 21. The configuration of substations 22 should be appropriately adjusted according to the size of their coverage area and monitoring needs. At the same time, the main station 21 set up in the main station layer serves as the central monitoring station and is the core of the entire monitoring system. The main station 21 is responsible for receiving data from each substation 22, and performing data aggregation, comprehensive analysis, and fault location. The main station 21 should be equipped with high-performance servers and data storage devices to ensure real-time processing and long-term preservation of data.

[0038] Specifically, for each substation 22, a processing and analysis unit for performing preliminary processing and analysis on the collected temperature data, and a temperature anomaly identification unit for identifying temperature anomalies based on the temperature data after preliminary processing and analysis are provided in the substation 22. The specific implementation process of preliminary processing and analysis and temperature anomaly identification is as follows:

[0039] The preliminary processing and analysis include: 1. Data cleaning: Substation 22 first cleans the temperature data received from the distributed temperature measurement optical fiber to remove abnormal values ​​or erroneous data caused by signal interference, transmission errors, etc. 2. Temperature data calibration: Based on the previous measurement data of the temperature measurement optical fiber under different environmental conditions (such as different seasons, different time periods, different pipeline conditions, etc.), a calibration model is obtained, and then the calibration model is used to calibrate the temperature data after data cleaning, so as to obtain the temperature data after preliminary processing. 3. Temperature anomaly point identification: The algorithm based on the combination of threshold and temperature change rate analysis is used to identify the temperature anomaly points in the temperature data after preliminary processing. Based on the data of the existing fixed-point monitoring equipment and the pipeline operation information, a reasonable temperature threshold is set. When the temperature at a certain location exceeds the threshold, it is preliminarily marked as a potential anomaly point. At the same time, the temperature change rate of each potential anomaly point relative to its adjacent preliminary processed temperature data is calculated. If the temperature change rate exceeds the preset change rate threshold, the corresponding adjacent preliminary processed temperature data also belongs to a potential anomaly point, and the potential anomaly point is further confirmed as a temperature anomaly point.

[0040] After the substation 22 completes the above-mentioned preliminary processing and analysis of the collected temperature data and identifies the temperature anomaly point, the relevant data will be uploaded to the main station 21 in the main station layer. The relevant data uploaded by the substation 22 to the main station 21 include: 1. Processed temperature data: The substation 22 summarizes and packages the cleaned and calibrated temperature data at a certain time interval (such as every 15 minutes or half an hour). 2. Detailed information of the anomaly point: The substation 22 sends the location information of the temperature anomaly point to the main station 21 (accurate to the specific location coordinates on the distributed temperature measurement optical fiber or the specific section and location identification of the corridor), and also sends the temperature value of the temperature anomaly point, the timestamp of the anomaly, the duration of the anomaly, and the temperature gradient information of the area near the temperature anomaly point (that is, the temperature difference of adjacent points). 3. Substation status information: The substation 22 regularly sends its own status information to the main station 21, including the operating temperature, power supply voltage, communication connection status (such as signal strength, data transmission success rate, etc.) of the substation 22 equipment, and the load status of the data processing unit (including the processing and analysis unit, the temperature anomaly identification unit and other processing units).

[0041] Specifically, for the main station 21, a data aggregation unit for data aggregation, a comprehensive analysis unit for comprehensive analysis, and a fault location unit for fault location are provided in the main station 21. The implementation contents of data aggregation, comprehensive analysis and fault location are as follows: Data aggregation includes two items: 1. Multi-substation data integration: The main station receives temperature data and abnormal point information from each substation after preliminary processing. These data are classified, stored and integrated according to different areas of the corridor, different lines and the time sequence of data collection. Based on the geographic information system (GIS), the temperature data of the areas covered by each substation are intuitively mapped to the three-dimensional model of the corridor, and a complete urban corridor temperature database is constructed to realize the visual aggregation of data, so that managers can quickly understand the overall picture of the temperature distribution of the entire corridor system. 2. Historical data archiving: Archive and manage the historical data accumulated over a long period of time, statistically archive the temperature data according to the time periods of day, week, month, year, etc., record the temperature mean, maximum, minimum and temperature change trend of each area of ​​the corridor in different time periods, and provide a data basis for subsequent comprehensive analysis.

[0042] Comprehensive analysis includes: 1. Temperature trend analysis: Based on the summarized historical temperature data and real-time temperature data, the machine learning data analysis algorithm is used to analyze the temperature change trend of each area of ​​the corridor. For example, by conducting long-term tracking analysis of the distributed temperature measurement optical fiber data in a certain section, it is determined whether the temperature in the area has a trend of gradual increase or decrease, and whether this trend exceeds the normal range (refer to the reasonable threshold set by historical data of the same period and engineering experience). If it is found that the temperature of a certain section of the corridor shows a continuous abnormal upward trend, it may indicate that there are potential thermal fault hazards inside the corridor, such as cable overload heating, pipeline insulation layer damage, etc., which require further in-depth analysis. 2. Abnormal point correlation analysis: When multiple substations report temperature abnormal points, the main station performs correlation analysis on the location, occurrence time, temperature value and other information of these abnormal points. Determine whether these abnormal points have some spatial or temporal correlation, and find possible systemic faults or external interference factors. For example, if the temperature of abnormal points in multiple adjacent substations shows a similar upward trend and is highly synchronized in time, it may be due to the influence of external heat sources in the area (such as nearby construction fires, thermal pipeline leakage, etc.).

[0043] Fault location includes: a GIS system is integrated in the main station. Based on the detailed information of the temperature anomaly points reported by the substations, combined with the structural layout of the corridor and the distribution of equipment, the high-precision positioning technology of distributed temperature measurement optical fiber is used to accurately lock the fault location.

[0044] like Figure 1 As shown, the monitoring and early warning module 3 communicates with the main station 21 to obtain its temperature data, basic information parameters of the pipeline corridor, fault location and other data, and performs early warning level classification and early warning information push.

[0045] Specifically, for the monitoring and early warning module 3, a warning level division unit for dividing warning levels and a warning information push unit for pushing warning information are provided in the monitoring and early warning module 3. The implementation contents of the warning level division and the warning information push are as follows:

[0046] Warning level classification: According to the results of comprehensive analysis and fault location, the operation status of the corridor is risk assessed, and the warning level is divided into three levels: mild warning, moderate warning and severe warning. Mild warning means that there are some potential abnormal conditions in the corridor, but it has not posed a serious threat to normal operation, and only the monitoring and inspection frequency need to be strengthened; moderate warning means that the risk of failure is high, and maintenance personnel need to be arranged in time to conduct on-site investigation and treatment, but it does not affect the overall operation of the corridor; severe warning means that the corridor has a serious fault or a major safety accident is about to occur, and emergency measures need to be taken immediately (such as power outage, evacuation of personnel, activation of fire protection system, etc.), and relevant departments and personnel are notified for emergency disposal. Warning information push: Warning information is pushed to relevant management personnel, maintenance personnel and emergency command center in a timely manner through various communication methods (such as SMS, email, sound and light alarm, monitoring platform pop-up window, etc.). Warning information includes detailed content such as fault location, fault type, warning level, possible impact range, etc., to ensure that the receiving personnel can quickly understand the abnormal situation of the corridor.

[0047] like Figure 1 As shown, the repair guidance feedback module 4 is provided with a repair suggestion unit, a fault repair progress unit and a user feedback unit. The repair suggestion unit is connected to the main station 21 and the monitoring and early warning module 3 to obtain fault information, wherein the data summary information of the substation, the preliminary analysis results of the substation, the fault information associated with the corridor equipment and environmental parameter data, the corridor basic information data and the fault location are obtained from the main station; and the accurate temperature anomaly point analysis results and the early warning level are obtained from the monitoring and early warning module. According to the above-mentioned relevant fault information, a repair suggestion applicable to the level and type of fault is provided, including possible fault causes, repair methods and required materials, etc., to guide relevant personnel to quickly repair the fault. The fault repair progress unit tracks the progress of fault repair. Tracking the progress of fault repair means tracking the progress of fault repair and recording key information in the repair process, such as repair time, repair personnel, materials and equipment used, etc., which can be used for subsequent fault analysis and formulation of improvement measures. The user feedback unit is used to collect user feedback on system performance and repair suggestions, and continuously optimize the functions and performance of the system according to user feedback, so as to improve the practicality and reliability of the system.

[0048] like Figure 1 As shown, the user display module 5 is communicatively connected to the monitoring and early warning module 3 and the repair guidance feedback module 4. The user display module 5 provides a user-friendly operation interface for maintenance personnel to monitor the status of the pipeline corridor and receive fault alarms.

[0049] Among them, the user display module 5 receives temperature data, abnormal point information, and warning information details from the monitoring and early warning module 3; receives fault repair suggestions from the repair guidance module 4, and records the fault repair progress information and user feedback, and sends them back to the repair guidance feedback module 4.

[0050] Specifically, the user display module 5 is provided with a user interface, which is an interactive window between the monitoring system and the maintenance personnel, and provides a user-friendly operation interface for monitoring the status of the pipe gallery, receiving fault alarms, and providing real-time data display, fault alarms, historical data query, system configuration and user management functions, and supports mobile device access and multi-language interface, as well as remote control functions. The specific functions include:

[0051] 1. Real-time data display: The user interface can display the temperature data of each area in the corridor in real time, and intuitively show the temperature distribution and change trend through dynamic charts and maps.

[0052] 2. Fault alarm: When the system detects abnormal temperature or potential fault, the user interface will immediately issue visual and audible alarms, clearly indicate the fault location, and provide fault details.

[0053] 3. Historical data query: Users can access historical data records through the user interface, including temperature change curves, fault records and maintenance logs, for easy analysis and auditing.

[0054] 4. System Configuration: The user interface allows authorized users to configure system parameters such as temperature alarm thresholds, data sampling frequency, and fiber monitoring areas.

[0055] 5. User management: The user interface provides user account management functions, including user permission allocation, password modification and account locking, to ensure system security.

[0056] 6. Mobile terminal access: The user interface supports access from mobile devices, such as smartphones and tablets, enabling maintenance personnel to receive alarm information and monitor the status of the tunnel at any location.

[0057] 7. Multi-language support: The user interface provides a multi-language interface to meet the needs of users in different regions.

[0058] 8. Custom reports: Users can generate custom reports through the user interface, including daily reports, weekly reports and monthly reports, to facilitate regular evaluation of the operation status of the corridor.

[0059] 9. Data visualization: The user interface uses data visualization technology to present complex temperature data and system status in a graphical and color-coded manner to improve the readability and comprehensibility of information.

[0060] 10. Interaction design: The user interface adopts intuitive interaction design, such as touch screen operation, voice command and gesture control, to enhance user experience.

[0061] 11. Remote control: The user interface provides remote control functions, allowing maintenance personnel to remotely start fault diagnosis programs, adjust monitoring parameters or restart monitoring equipment.

[0062] 12. System Feedback: Users can provide feedback through the user interface, and the system will collect this feedback for future system upgrades and improvements.

[0063] 13. Help and support: The user interface has built-in help documents and online support links to provide users with operational guidance and technical support.

[0064] During the operation of the above-mentioned urban area-level corridor monitoring system based on distributed temperature measurement optical fiber and base station, the user logs in to the user interface, and the system displays the corresponding functional modules according to the user's permissions. The user views the temperature distribution of the corridor in the real-time data display module, and the system represents different temperature ranges through different colored areas on the map. When the system detects abnormal temperature, the user interface automatically pops up a fault alarm window to display the fault location and recommended maintenance measures. Maintenance personnel receive fault alarms through mobile devices and view fault details on the user interface. Maintenance personnel perform on-site fault maintenance, and the system tracks the progress of fault repair and records key information in the repair process, such as repair time, repair personnel, materials and equipment used, etc. Based on feedback, the system's functions and performance are intelligently optimized to improve the system's practicality and reliability.
