Description

Technical Field

[0001] This invention relates to the field of submarine cable monitoring technology, and in particular to a submarine cable monitoring system and a multi-dimensional data analysis and monitoring method. Background Technology

[0002] Submarine cables are cables laid on the bottom of oceans or lakes to transmit power or communication signals. Depending on their purpose, submarine cables are mainly divided into communication submarine cables and power submarine cables, which play a vital role in global communication, energy transmission and Internet connectivity.

[0003] Due to the unique environment of offshore wind power, offshore wind power system equipment is directly exposed to variable and even extreme climatic conditions, making it highly susceptible to the influence of the highly variable and complex natural environment near the coast, such as wave loads, sea ice loads, typhoon damage, earthquakes, and other limiting factors, as well as the effects of corrosive ions and high-intensity corrosion in the marine environment. Its structural durability and stability have become important issues for structural safety.

[0004] When a submarine cable breaks, it is very difficult to salvage the damaged cable and locate the fault point due to factors such as weather and tides. The repair process is time-consuming, difficult, and costly. In addition, it is also very difficult to track down and deal with the offending vessel after the cable anchor is damaged. Therefore, in order to address the above problems, a submarine cable monitoring system and a multi-dimensional data analysis monitoring method are proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a submarine cable monitoring system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a submarine cable monitoring system, characterized in that it includes a surface detection unit and an underwater detection unit, wherein the surface detection unit includes a video monitoring module for capturing images of surface activity, a radar monitoring module for monitoring the position and speed of objects on the surface, and a monitoring module for monitoring the propagation of communication signals on the surface. The underwater detection unit includes a burial depth detection module, a temperature detection module, a stress detection module, and a vibration detection module; The burial depth detection module includes a depth sensor for measuring the depth of underwater devices, a displacement sensor for ensuring the sensor's position, a signal transceiver submodule for receiving and transmitting signals, an optical detection submodule for acquiring optical images of the object being detected, an acoustic detection submodule for detecting and locating underwater targets, and a data processing submodule for integrating and calculating data to generate burial depth detection results.

[0007] In a preferred embodiment, the temperature detection module includes a temperature sensor and a data acquisition submodule.

[0008] The technical effect of adopting the above technical solution is that, with the help of the surface monitoring module and the underwater monitoring module, the system can monitor abnormal situations in real time, such as suspicious objects on the water surface or changes in the underwater environment, and issue early warnings in a timely manner. This real-time early warning mechanism can help relevant departments take measures quickly to prevent potential risks and losses.

[0009] In a preferred embodiment, the stress detection module includes a working strain gauge, a compensating strain gauge, a data acquisition submodule, and a transmission submodule.

[0010] The technical effect of adopting the above technical solution is that it can reduce measurement errors caused by temperature changes, thereby timely detecting possible stress anomalies or fatigue accumulation problems in submarine cables. When the stress exceeds the standard or approaches the limit, the system can issue an early warning to remind relevant personnel to take preventive measures.

[0011] In a preferred embodiment, the vibration detection module includes a vibration sensor for detecting the vibration state of an underwater structure, a signal processing submodule for performing preliminary processing on the signals collected by the vibration sensor, and a data acquisition submodule for acquiring data from the vibration sensor in real time and converting it into digital signals for subsequent processing.

[0012] The technical effect of adopting the above technical solution is that after receiving external input signals, it ensures that the vibration state of the underwater structure can be transmitted to the upper control system in a timely manner for further analysis and feedback, thereby quickly identifying vibration anomalies and issuing early warning signals.

[0013] In one preferred embodiment, the water surface detection unit includes a data storage submodule for storing water surface monitoring data and a data analysis submodule for performing preliminary analysis of the water surface monitoring data.

[0014] The technical effects of adopting the above technical solution are: past water surface condition records can be retrieved at any time, providing detailed data support for accident investigation and problem tracking; combined with the functions of the analysis module, the data can be further processed to generate trend analysis reports or risk assessment results.

[0015] In one preferred embodiment, the underwater detection unit includes a data storage submodule for storing underwater monitoring data and a data analysis submodule for performing preliminary analysis of the underwater monitoring data.

[0016] The technical effects of adopting the above technical solution are: it provides a foundation for subsequent historical data analysis and problem tracing, and the data analysis submodule can form an accurate trend prediction model based on historical data.

[0017] The present invention also adopts the following technical solution: a multi-dimensional data analysis and monitoring method for submarine cable monitoring, specifically including the following steps: S1, system initialization and calibration; S2, surface monitoring process; S3, underwater detection process; S4, data processing and storage; S5, anomaly detection and alarm; In a preferred embodiment, step S1 specifically involves: activating the surface detection unit and the underwater detection unit; ensuring all sensor modules are functioning correctly; The specific steps of step S2 are: capturing water surface activity, transmitting the captured information, and detecting abnormal water surface activity. The specific steps of step S3 are: detecting underwater activities, integrating the detection data of each sub-module, and sending them to the data processing system; As a preferred embodiment, step S4 specifically involves storing the data captured from the water surface and the data detected underwater, performing further analysis, and then generating a monitoring report.

[0018] The specific steps of step S5 are as follows: By integrating the data from each detection module, the status of the submarine cable is monitored in real time, and an alarm is automatically triggered when an abnormality occurs to remind the staff.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The surface monitoring unit integrates video, radar, and communication signal monitoring. Cameras capture moving images, radar monitors object position and speed to identify potential threats to the submarine cable, and communication monitoring ensures continuous and stable signals. The underwater monitoring unit's depth module integrates data from multiple sensors to accurately monitor the cable's condition. The system detects cable damage or displacement and stores monitoring data in real time. The data analysis submodule uses algorithms to extract information, helping to promptly identify potential problems. This design, through multiple monitoring methods on the surface and underwater, allows for comprehensive real-time monitoring of environmental changes around the cable. Radar and video monitoring modules can detect vessels or other objects that may threaten the cable immediately and provide early warnings to prevent damage. Addressing the challenges of traditional submarine cable monitoring, which is limited by weather, tides, and other factors, resulting in difficult and time-consuming repairs, the real-time monitoring and rapid early warning system can significantly reduce the frequency of cable damage, thereby lowering repair costs.

[0020] A temperature sensor measures the underwater environment temperature and transmits the data to the data acquisition submodule. Working strain gauges collect stress and strain values ​​of the underwater structure, while compensating strain gauges perform temperature compensation to correct the impact of temperature on stress data. Vibration sensors monitor the vibration state of the underwater structure. A signal processing submodule performs preliminary processing on the signals collected by the sensors, and the data acquisition submodule converts the vibration data into digital signals. This design allows for real-time tracking of temperature changes in the submarine cable's environment, preventing damage caused by temperature fluctuations, accurately reflecting stress changes experienced by the cable, and reducing temperature interference with stress data. This enables personnel to promptly detect abnormal cable vibrations and prevent damage caused by prolonged vibration. This effectively reduces the interference of environmental temperature changes on stress detection data, allowing personnel to identify potential problems earlier.

[0021] The system deploys sensor units both on and underwater to capture physical signals in the environment that may affect the safe operation of submarine cables in real time. These signals include changes in parameters such as vibration, stress, temperature, and depth. By sensing these changes through physical sensors, the system can detect the operational status of the underwater cable and potential anomalies. This real-time detection and data processing allows the submarine cable system to maintain safe operation under various environmental conditions. Furthermore, through multi-dimensional data analysis, the system can effectively identify threats to the submarine cable in the surface or underwater environment and promptly notify maintenance personnel, reducing the risk of cable breakage or damage.

[0024] Example 1: As Figure 1 and Figure 2 As shown, this embodiment provides a submarine cable monitoring system, including a surface detection unit and an underwater detection unit. The surface detection unit includes a video monitoring module for capturing images of surface activity, a radar monitoring module for monitoring the position and speed of objects on the surface, and a monitoring module for monitoring the propagation of communication signals on the surface.

Example 3: According to as follows Figure 1 , Figure 5 and Figure 6 The document describes a submarine cable monitoring system and a multi-dimensional data analysis monitoring method for submarine cables, such as... Figure 6 and Figure 7 As shown, the specific steps include: S1. System Initialization and Calibration; Start the surface detection unit and underwater detection unit. Ensure all sensor modules are functioning correctly. During system initialization, start the surface detection unit and underwater detection unit. The system will communicate with each sensor through the signal transceiver submodule to ensure the proper functioning of modules such as depth sensors, displacement sensors, temperature sensors, stress detectors, and vibration sensors. Calibration at this stage not only ensures the accuracy of sensor data in subsequent operations but also maintains stable operation of the equipment by integrating the signal transceiver and data acquisition submodules, laying a solid foundation for subsequent data acquisition and processing. S2. Surface Monitoring Process: This process involves capturing surface activity, transmitting the captured information, and detecting abnormal surface activity. During surface monitoring, the video monitoring module captures surface activity and converts it into image data, while the radar monitoring module detects the position and speed of objects on the water surface. Data is transmitted to the data storage submodule for storage, and the data analysis submodule performs preliminary analysis to identify any anomalies, such as abnormally close objects or abnormal surface signals. This ensures that potential threats during surface activity can be detected promptly, preventing surface events from interfering with or damaging the submarine cable system. S3. Underwater Detection Process: This process detects underwater activities and integrates the detection data from various submodules, sending it to the data processing system. During underwater detection, the sensors work collaboratively: depth sensors monitor the burial depth of the submarine cable, temperature sensors monitor underwater temperature, stress sensors detect the stress on the cable, and vibration sensors monitor structural vibration. The data collected by each submodule is initially processed by the signal processing submodule before being transmitted to the data processing system for integrated analysis. Through comprehensive processing of multi-dimensional data, the system can gain a complete understanding of the underwater environment and the operational status of the submarine cable, ensuring its safe operation under predetermined conditions. S4. Data Processing and Storage: Data captured from the water surface and underwater detection are stored, further analyzed, and then a monitoring report is generated. In the data processing and storage stage, the surface and underwater detection data are initially processed and stored in the data storage submodule. Next, the data processing module performs in-depth analysis of the data from each sensor, generating a comprehensive monitoring report. This stage of data processing goes beyond simply storing monitoring data; it uses algorithms to analyze and identify potential anomalies, generating a comprehensive assessment of the system's operational status. This helps operators make regular maintenance and analytical decisions, preventing potential failures. S5. Anomaly Detection and Alarm: By integrating data from various detection modules, the system monitors the submarine cable's status in real time. An alarm is automatically triggered upon detecting anomalies, alerting personnel. When the system detects data exceeding normal ranges on the water surface or underwater—such as increased temperature, overload, abnormal vibration, or insufficient burial depth—it automatically issues an alarm through the alarm module, notifying operators. Real-time data analysis ensures that any anomalies are quickly detected and responded to immediately by the alarm system, providing operators with an opportunity for immediate intervention and preventing damage to the submarine cable system caused by external interference or internal faults. The real-time early warning mechanism improves the system's response speed and reduces the risk of submarine cable damage.
