Description

Technical Field

[0001] The invention belongs to the field of marine environment information systems, in particular to a three-dimensional monitoring system for marine area environment. Background Art

[0002] Long-term and continuous marine environmental monitoring is an important means to achieve the rational use of marine resources, protect the marine ecological environment, reduce the risk of marine disasters, promote scientific research and support economic development. However, the existing marine regional environmental monitoring system does not have three-dimensional monitoring, and has deficiencies and drawbacks in technical structure and methods, which limits its scope of application and the practicality of data.

[0003] First, the existing monitoring software can only meet the functions of video monitoring, point monitoring data collection and query, but the data density is low, and it can only be viewed but not used; in addition, these software usually cannot effectively integrate multi-source data such as monitoring data, remote sensing images, and pattern reanalysis, resulting in information islands and affecting the comprehensive analysis and utilization of data. At the same time, although some systems provide data display functions, they often lack effective three-dimensional visualization methods, making it difficult to intuitively reflect the three-dimensional structure and dynamic changes of the ocean.

[0004] In terms of methods, existing technologies often only focus on monitoring local areas or specific parameters, and cannot fully cover various elements of the marine environment, resulting in incomplete monitoring results. In addition, many monitoring systems are unable to achieve real-time data updates, resulting in monitoring results that may not reflect the latest changes in the marine environment in a timely manner. The marine environment is complex and changeable, and existing monitoring systems may not perform well in the face of extreme weather or large-scale pollution incidents. They lack the functions of macro-environmental monitoring and prediction, disaster warning, and decision-making support, and are unable to provide timely and effective marine monitoring and prediction data and disaster warning information to relevant marine-related institutions and enterprises at regular intervals and locations, helping relevant units to take timely response measures and avoid risks. Summary of the invention

[0053] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] like Figure 1 As shown in the figure, the architecture of the marine area environment three-dimensional monitoring system is divided into a data resource layer, a platform service layer, and a user layer. The data resource layer is a data access module, which designs a unified data interface and data access format, accesses buoy monitoring data, remote sensing data, model algorithm data, and other multi-source heterogeneous data, and classifies and reorganizes the data to provide data support for upper-level applications. The platform service layer includes a holographic marine environment module, an information product service module, and a system configuration and management module; the user layer includes relevant government departments, scientific research institutions, and industry users, and designs a unified system portal to facilitate user login and access to achieve human-computer interaction.

[0055] The system configuration and management module includes information product line management, system operation monitoring and user information management. Among them, the information product line management uses the data in the data access module as the input source, configures the automated data production line, and produces marine environment monitoring information products, marine environment prediction information products, and environmental comprehensive assessment information products. In addition, it also provides an information product application review function to review the data application submitted by the user in the information product service. System operation monitoring mainly monitors and manages the system operation to ensure the safe and normal operation of the system. For data access interruptions or abnormal situations in the information product production line, instant email reminders are sent to the relevant person in charge to solve the problem in a timely manner. The user information management module mainly manages the platform application status and user information, including platform data status, system usage, user registration and account management, user role authority management and other functions.

[0056] The information product service module provides external users with marine environment monitoring information service products, marine environment prediction information service products and comprehensive environmental assessment information products. Among them, marine environment monitoring information products mainly include water quality environment, hydrodynamic parameters, typical disasters and long-term data of regional environmental distribution based on satellite remote sensing inversion, providing guidance for regional marine construction planning. Marine prediction environment information service products mainly include three-dimensional prediction information products of temperature and salinity flow and three-day prediction information products of seawater temperature and oxygen, providing marine regional environmental early warning and forecasting services. Comprehensive environmental assessment information products include ecological carrying capacity assessment reports, production capacity assessment reports and marine ecological environment quality assessment reports to increase the overall understanding of the marine ecological environment. In addition, this module provides information product service application functions, and users can query the corresponding information product application through data type retrieval and map retrieval.

[0057] The holographic ocean environment module preprocesses and visualizes the data in the data access module. The processed data is divided into four parts for holographic display, including air-space stereoscopic monitoring, marine environment situation, regional facility distribution situation, and regional environmental disaster situation. Among them, the air-space-ground-sea stereoscopic monitoring collects and integrates physical photos and images of remote sensing satellites, drones, and buoys, and builds a model library of marine environment observation equipment. The model library includes a remote sensing satellite display model library, a drone display model library, a buoy display model library, and a submarine equipment model library. Provide the number and model images of remote sensing satellites used for system visualization; provide the number and model images of drones, including multi-rotor or fixed-wing drones; provide buoy model images used to display buoys, including buoy prototype stereo models and anchor structures; provide model images used to display submarine equipment. Visualize and integrate models such as high-altitude remote sensing, sky drones, sea surface buoys, and submarine equipment to display a three-dimensional monitoring network of air, space, sea, and land.

[0058] The marine regional environmental situation is used to display marine environmental monitoring and prediction data such as buoy monitoring data, satellite remote sensing data products, three-dimensional temperature-salinity flow model data, and three-day seawater temperature and oxygen forecast data in the data access module. This module provides various forms of data visualization, including query retrieval, layer overlay, layer carousel, multi-window display, and vector data particleization to achieve three-dimensional dynamic perception of the marine environment. At the same time, it provides multi-dimensional display and query retrieval of buoy monitoring data at different time series, different depths, and different elements. The real-time monitoring data of the buoy is displayed using independent real-time frame data, and the historical data of the buoy is displayed using line graphs, rose graphs, and other methods to display different elements.

[0059] The regional facility structure situation mainly displays the distribution of offshore facilities, aquaculture structures and functional areas. It includes offshore platforms, wind power, etc. The aquaculture structures include aquaculture facilities such as cages and rafts, as well as the distribution of national and provincial marine ranches. Functional areas include shellfish bottom seeding areas and marine treasure bottom seeding areas.

[0060] Regional environmental disaster situation is used to show the distribution trend of marine ecological environmental disasters. Disaster distribution and image area data are obtained through satellite remote sensing inversion, including sea ice, enteromorpha, oil spills and red tides. When a disaster occurs, enterprises and institutions within the disaster coverage area are automatically warned. Entering the name of an enterprise or institution can display information on all disasters within the sea area where it is located, providing decision-making support services for marine safety management and control.

[0061] like Figure 2 The figure shows the main process logic of the marine area environment stereoscopic monitoring system provided by the embodiment of the present invention. The marine area environment stereoscopic monitoring system accesses satellite remote sensing, drone, buoy and other monitoring data through the data access module, as well as three-dimensional temperature-salinity flow prediction data, three-day seawater temperature-oxygen prediction data and other patterns and artificial intelligence model algorithm data.

[0062] With the data in the data access module as the input source, configure the automated data production line, and produce marine environment monitoring information products, marine environment prediction information products, and environmental comprehensive assessment information products through information product line management. The configured data production line can be saved as a template and reused. Among them, the marine environment monitoring information products include water quality parameter remote sensing monitoring products, hydrodynamic parameter remote sensing monitoring products, ecological environmental disaster remote sensing monitoring products, and offshore facility remote sensing monitoring products. In the information product service configuration function, first set the water quality parameter inversion type, hydrodynamic parameter inversion type, facility identification type, and disaster inversion type, then select the working mode (including satellite remote sensing, drone remote sensing, and satellite and drone remote sensing), product production time, time interval, input data reading path, and product output path. Marine environment prediction information products include three-dimensional temperature-salinity flow prediction data products and seawater temperature-oxygen three-day prediction data products. In the information product service configuration function, enter the reading path and product output path of the three-dimensional temperature-salinity flow prediction data and the three-day seawater temperature-oxygen prediction data respectively to produce an automated data production line. Comprehensive environmental assessment information products include ecological carrying capacity assessment reports, yield assessment reports and ecological environment quality assessment reports. In the information product service configuration function, select the assessment report type, data type, data time, time interval range, input data reading path, and product output path.

[0063] The information product service module manually or automatically publishes products produced by information product line management and displays successfully published data products. Users can query the corresponding information product application through data type retrieval and map retrieval. The administrator reviews it through the information product service review function. After the review is passed, the user can download and use it. When data access is interrupted or the information product production line is abnormal, the system operation monitoring will send an instant email reminder to the relevant person in charge to solve the problem in time.

[0064] The holographic ocean environment module obtains the data in the data access module for visualization preprocessing and holographic display. Data conversion is performed for the three-dimensional temperature-salinity flow prediction data and remote sensing data. Based on the efficient caching and rendering technology of tile data, combined with the GDAL raster-to-vector conversion open source library, the three-dimensional temperature-salinity flow real-time prediction data, the three-day seawater temperature-oxygen prediction data, and remote sensing data are efficiently processed into TIFF and JSON data formats that can be uploaded. Large-scale vector data thinning and efficient loading technology are used for a large amount of vector data. Through the Douglas-Peuker algorithm (this algorithm is an algorithm that approximates a curve as a series of points and reduces the number of points. It has the characteristics of no deformation during translation and rotation. After the curve and threshold are given, the sampling result is certain.) The vector is displayed in layers, and the resolution is directly used as the threshold of the Douglas-Peuker algorithm. The approximate vector of the layer can be obtained, which is basically similar to the original vector in visual effect. While basically ensuring the data loading effect, the loading time is effectively improved; through pyramid slicing, OGC standard data efficient cache acceleration and other technologies, the processed TIFF data and satellite remote sensing data are released as services. Real-time massive data efficient drawing technology is adopted to organically combine the server and the client to achieve efficient drawing of massive real-time location data, take advantage of the resource advantages of the background service, connect the data source data, and perform point cloud clustering and release services for the overall data distribution in real time, and provide a data query interface within the regional range. When the client is displaying in 3D, at the level of the ball (the level of the ball is measured by the camera height, the higher the level of the ball, the lower the camera height / relatively low), the first level (point mode) uses the point cloud data published by the service to display the data distribution as a whole. When the level of the ball is higher and enters the regional range, the data in the requested area is used to realize the loading scheduling of the second level (icon mode) and the third level (model mode). The data is clustered using a combination of the grid method and the k-means algorithm, which improves the efficiency and accuracy of data clustering. The hardware resources of the local computer are used to separate the management and drawing of data, improve the efficiency of drawing massive data, and show better 3D effects.

[0065] The data that has been pre-processed for visualization are holographically displayed according to the three-dimensional air-space monitoring network, regional marine environmental situation, regional facility structure situation, and regional environmental disaster situation. The three-dimensional air-space monitoring network visualizes the remote sensing satellite parameter information and pictures, drone parameter information and pictures, buoy parameter information and pictures, and submarine equipment parameter information and pictures obtained through the data access module. The regional marine environmental situation uses a large-scale multi-layer time series method to display the water quality remote sensing monitoring data, hydrodynamic remote sensing monitoring data, three-dimensional temperature and salt flow prediction data, and seawater temperature and oxygen three-day prediction data obtained through the data access module, and can classify, grade, and retrieve historical large-scale element data in time series; at the same time, it provides multi-dimensional display and query retrieval of buoy monitoring data at different time series, different depths, and different elements. The real-time monitoring data of the buoy is displayed using independent real-time frame data, and the historical data of the buoy is displayed using line charts, rose charts, and other methods. The regional facility structure situation uses a three-dimensional model based on 3DMAX software to display the offshore facility remote sensing monitoring data, offshore aquaculture structure distribution, and functional area distribution data obtained through the data access module. Offshore facilities include offshore platforms, wind power, etc., and aquaculture structures include cages, rafts and other aquaculture facilities as well as the distribution of marine ranches. Functional area distribution includes shellfish bottom seeding areas and marine treasure bottom seeding areas. Regional environmental disaster situation displays the location, distribution and drift range of disasters through layer carousel and query of sea ice extraction data products, enteromorpha disaster extraction data products, red tide disaster extraction data products and oil spill disaster extraction data products obtained through the data access module. When a disaster occurs, disaster warning information is automatically sent to enterprises and institutions within the disaster coverage area. Entering the name of an enterprise or institution can display information on all disasters within the sea area where it is located.
