Description

Technical Field

[0001] This invention relates to the field of sea gate control technology or other related fields. Specifically, it relates to a gate control method and device, and electronic equipment based on a sea gate control system. Background Technology

[0002] The impact of long-period waves is a common problem in port and terminal operations, especially in offshore coastal engineering, where they pose a serious challenge to the safety and efficiency of terminal operations. To mitigate the impact of long-period waves, breakwaters are widely used in coastal engineering. While breakwaters can effectively block and weaken offshore waves, they cannot completely eliminate the impact of long-period waves entering the harbor through entrances. In particular, under the influence of long-period waves, waves can still penetrate through the channel between the breakwater and the harbor basin, adversely affecting vessels at berths. When the long-period waves are large, even with a breakwater, waves within the harbor can still threaten terminal operations.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0033] To facilitate understanding of the present invention by those skilled in the art, some terms or nouns involved in the various embodiments of the present invention are explained below:

[0034] A breakwater is a marine engineering structure used to protect ports from the impact of waves. It is custom-designed based on the topography, meteorological and hydrological conditions of the project area to minimize the impact of waves on the harbor waters.

[0035] The gate area, comprising gates, lock heads, and hoisting mechanisms, is the core of the sea lock control system. Based on wave monitoring and forecasting results, the gates in this area can automatically close or open under specific conditions to control or prevent the entry of waves.

[0036] The connecting zone is an important transitional area between the breakwater and the gate area, mainly used for structural stabilization and connection.

[0037] The PDI-WFS model, or PDI Wave Forecasting System, is an advanced wave forecasting system designed for port and waterway engineering needs. It can predict wave fields over a future period. Based on the WW3 model, it provides wave time series, average wave parameters, and spectral partition data, supporting refined management and decision-making.

[0038] It should be noted that the gate control method and device based on the sea gate control system in this disclosure can be used in the field of sea gate control technology for gate opening and closing control of coastal engineering projects under long-period wave conditions based on a novel sea gate control system, and can also be used in any field other than the field of sea gate control technology. In the case of gate opening and closing control of coastal engineering projects under long-period wave conditions based on a novel sea gate control system, this disclosure does not limit the application field of the gate control method and device based on the sea gate control system.

[0039] It should be noted that the information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, and displayed data) collected in this public disclosure are information and data authorized by the user or fully authorized by all parties.

[0041] The following embodiments of the present invention can be applied to various gate control systems / applications / equipment based on sea lock control systems. The present invention is applicable to the fields of marine engineering, port construction, and operation and maintenance, especially to port basins, wharves, and dry docks located in open sea areas and susceptible to long-period waves. In specific application scenarios, during the port design phase, the present invention can be used to evaluate and plan the optimal combination of breakwaters and sea locks to improve the overall safety and economy of the port.

[0042] This invention achieves effective management of long-period waves and real-time optimization of the dock operation environment by adding a sea gate to the breakwater entrance and integrating an intelligent wave prediction system. When a long-period wave is detected to exceed a preset threshold, the sea gate can be quickly closed to cut off the direct impact of the wave on the port area, significantly improving the safety of ship berthing and cargo loading and unloading.

[0043] Accurate prediction of wave conditions allows for the rational planning of operational windows, preventing operational interruptions or delays due to unforeseen severe weather, thereby improving the overall operational efficiency of the port. Compared to traditional static breakwater measures, dynamic seawall control systems can respond more flexibly to changing marine environments, reducing unnecessary resource waste and lowering long-term operating costs.

[0044] By rationally designing wave-damping zones, this invention can not only reduce wave damage to wharf infrastructure but also alleviate pressure on the ecological environment of nearby waters, achieving a win-win situation for economic development and environmental protection.

[0045] The present invention will now be described in detail with reference to various embodiments.

[0046] Example 1

[0047] According to an embodiment of the present invention, an embodiment of a gate control method based on a sea gate control system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0048] According to one aspect of the present invention, a gate control method based on a seawall control system is provided. The seawall control system includes at least a gate area, which includes a gate, a gate head, and gate control equipment. The gate is located at the entrance of the breakwater.

[0049] Figure 1 This is a schematic diagram of an optional sea gate control system according to an embodiment of the present invention, such as... Figure 1 As shown, the sea lock control system includes: a breakwater area, a gate area (including gates and gate heads), a wave-dissipating area, and a connecting area.

[0050] The design of the breakwater must be based on data on the topography, meteorology, hydrology, geology, and sediment of the project area. Its main function is to reduce the impact of waves from the open sea. This breakwater can be regarded as the first line of defense in this embodiment, helping to reduce the energy of external waves. Through detailed analysis of topographic, meteorological, and hydrological data, the breakwater can specifically reduce wave impact and create a relatively calm water environment within the harbor.

[0051] The gate remains open during periods of lower long-period waves and closed during periods of higher long-period waves to ensure the safety and efficiency of port operations. The gate area includes the gate itself, the gate head, and the hoisting mechanism. The gate can flexibly adjust its opening and closing status based on real-time wave data monitoring, helping to limit wave entry into the port during periods of active long-period waves, thus protecting berth operations from disturbance. The gate head, as the supporting structure for the gate, enhances its stability and safety, ensuring normal operation under high loads.

[0052] The connecting zone is the area where the breakwater and the gate connect, and its main function is reinforcement. Serving as a bridge between the breakwater and the gate area, it strengthens the overall structure. The connecting zone not only helps ensure a stable connection between the various parts but also optimizes the direction of water flow and wave propagation paths, further enhancing the overall efficiency of the system.

[0053] A breakwater zone serves to reduce the impact of long-period waves that have already entered the harbor. It can be achieved by extensively deploying boulders, slopes, vegetation, etc., in areas that do not disrupt operations. By establishing breakwater zones, the residual wave energy that has already penetrated the breakwater and gate areas can be further mitigated. By placing natural or man-made barriers such as boulders, slopes, and vegetation in key areas that do not affect operations, it helps to weaken waves and reduce their potential threat to ships and dock facilities.

[0054] This embodiment, through the coordinated operation of the four key areas mentioned above, can effectively control the impact of long-period waves on port operations, helping to improve the safety and efficiency of terminal operations while reducing reliance on adverse weather conditions. Through dynamic monitoring and intelligent adjustments, this embodiment enables proactive management and adaptation to changes in complex marine environments, providing a more reliable and flexible solution for port operations.

[0055] Optionally, the breakwater area in the lock control system includes at least: a breakwater, the direction and length of which are determined according to the topography, meteorology, hydrology, and geology of the target lock project, used to weaken the impact of offshore waves on the harbor; a connecting area, connecting the breakwater and the gate, wherein the gate type includes: rotary type, and the gate opening and closing mechanism includes: hydraulic opening and closing mechanism; and a wave-dissipating area, used to weaken the impact of long-period waves that have entered the harbor, wherein the wave-dissipating area includes at least one of the following: boulders, slopes, and pre-planted plant species.

[0056] It should be noted that the direction and length of the breakwater in this embodiment are not arbitrarily set, but determined after careful consideration of detailed data such as the topography, meteorology, hydrology, geology, and sediment of the target sea gate project site. This helps to minimize the impact of offshore waves on the harbor waters and provides a stable foundation for the other components of this embodiment. The connecting area in this embodiment is responsible for linking the breakwater and the gate, ensuring a stable connection between the two structures, and providing support for the normal operation of the gate.

[0057] It should be noted that the gate in this embodiment, as the key to controlling the entry of long-period waves into the harbor basin, can adopt a rotary design, which helps to quickly respond and adjust the opening or closing state. The gate's opening and closing mechanism adopts a hydraulic opening and closing mechanism. This mechanism is characterized by its high efficiency and reliability, which can ensure that the gate reacts quickly when needed and effectively manages the entry and exit of waves.

[0058] In addition, the purpose of setting up a breakwater zone in this embodiment is to further reduce the energy of long-period waves that have already passed through the breakwater and gate areas, ensuring the safety and stability of the port environment. The breakwater zone includes, but is not limited to, the use of boulders, slopes, or pre-planted vegetation, which help disperse and absorb wave energy, reducing the direct impact on the dock operation area.

[0059] Optionally, the wave-dissipating zone is set up in the following way: the wave conditions of the wharf of the target sea lock project are analyzed, and the main wave direction is determined based on the wave analysis results; wave model calculation is performed based on the main wave direction to determine the wave propagation diagram; the direction and location of wave reflection are determined according to the wave propagation diagram, wherein the location does not affect the wharf operation, and the positive reflection location includes the wharf location; the secondary reflection location is selected as the optimal wave-dissipating zone.

[0060] When setting up the breakwater zone, firstly, an in-depth analysis of the wave conditions at the target sea lock project's wharf was conducted. Based on the analysis results, the dominant wave direction was determined, which forms the basis for optimizing the breakwater zone layout. Secondly, wave model calculations were performed based on the dominant wave direction to obtain detailed wave propagation diagrams, revealing the specific paths and characteristics of wave propagation within the harbor. Thirdly, wave reflection patterns were analyzed based on the wave propagation diagrams to determine the direction and location of reflections. The key was to select reflection locations that would not negatively impact wharf operations, avoiding secondary interference that positive reflections might cause to the wharf. Finally, the secondary reflection location was selected as the optimal breakwater zone. This location typically does not directly involve the core operational area of ​​the wharf. By setting up breakwater facilities such as boulders, slopes, or vegetation, the energy of long-period waves can be effectively reduced without affecting normal operations, further optimizing the safety and efficiency of the harbor's operational environment.

[0061] Applied to the above Figure 1 The diagram illustrates the control system of the sea gate. Figure 2This is a flowchart of an optional gate control method based on a sea lock control system according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0062] Step S201: Input the topographic range data and topographic grid of the target sea lock project into the wave forecasting model. Use the wave forecasting model to simulate the waves at the target location outside the project area based on the weather forecast data for a predetermined time period. Output the wave sequence data of the target location within a predetermined time period in the future. The wave sequence data includes at least: wave height data and period data.

[0063] In this embodiment, the topographic range data of the target sea lock project may include detailed information such as sea area boundaries, harbor basin depth, and seabed topography. This data helps the model to accurately understand and simulate the marine geographical environment around the project, providing a basis for subsequent wave simulation.

[0064] It should be noted that gridding the input terrain data refines the terrain features and improves the accuracy of wave forecasting. The grid size can be adjusted according to the terrain complexity and forecast accuracy requirements, which helps the model to analyze the propagation characteristics of ocean waves under different terrain conditions in greater detail.

[0065] Then, based on the above-mentioned terrain data and grid division, this embodiment uses a wave forecasting model (for example, the model can be the PDI-WFS model or its derivative) to simulate ocean waves at the target location point outside the project area (which can be defined as point P in this embodiment) based on weather forecast data for a period of time in the future. Optionally, the weather forecast data may include meteorological parameters such as wind speed, wind direction, and air pressure.

[0066] During the wave simulation process, the model calculates the propagation, refraction, and attenuation of wind waves and swells in the target sea lock project area, and outputs wave sequence data for the target location point within a predetermined time period in the future. The duration of the forecast data can range from several hours to several days, depending on the model's capabilities and user needs.

[0067] The wave sequence data output by the model includes at least wave height data, period data, and wave direction data. Wave height data describes the average height of the waves at the target location and is one of the key indicators for assessing the necessity of closing the sea gate. Period data reflects the frequency characteristics of the waves. Long-period waves usually pose a greater threat to the safety of the wharf. Wave direction data indicates the direction of wave propagation and helps to understand how waves affect the harbor basin and wharf area.

[0068] Optionally, the step of inputting the topographic range data and topographic grid of the target sea lock project into a wave forecasting model, and using the wave forecasting model to simulate ocean waves at the target location outside the project area based on weather forecast data for a predetermined time period, includes: reading the boundary data of the target sea lock project using the wave forecasting model; inputting the topographic range data and topographic grid of the target sea lock project into the wave forecasting model, and calculating the grid point data and spectral data of each topographic grid through the wave forecasting model, wherein the grid point data includes: mean wave parameters, and the spectral data includes: local wave spectrum and sub-grid wave data; and simulating ocean waves at the target location outside the project area based on the grid point data and spectral data of each topographic grid, combined with weather forecast data for a predetermined time period, through the wave forecasting model.

[0069] First, this embodiment utilizes a wave forecasting model to read the boundary data of the target sea lock project. This helps the model understand the geographical boundary conditions of the project area, including but not limited to the shape and depth of the sea area and its boundary with the land. Accurate input of boundary data provides a basic framework for subsequent wave simulation, ensuring the reliability of the calculation results. Next, this embodiment inputs the topographic extent data and topographic grid of the target sea lock project into the wave forecasting model. The topographic extent data can cover the seabed topography and geomorphological features within the project area, while the topographic grid subdivides the complex terrain into a series of smaller units, facilitating more accurate calculations by the model. Through this input, the model can handle the complex terrain of each grid, performing in-depth simulations of wave propagation paths, energy distribution, and morphological changes.

[0070] Based on topographic data and grid division, this embodiment calculates grid point data and spectral data for each topographic grid using a wave prediction model. Grid point data mainly includes mean wave parameters, such as mean wave height and mean period, reflecting the general characteristics of ocean waves within a specific grid. Spectral data may include local wave spectra and gridded wave data, providing details of the distribution of wave energy at different frequencies and directions, which helps in analyzing the interaction between long-period waves and other wave components.

[0071] Finally, this embodiment utilizes the calculated gridded and spectral data, combined with weather forecast data for a predetermined time period, to simulate ocean waves at the target location outside the engineering area. Weather forecast data typically includes key parameters such as wind speed, wind direction, and air pressure. Combining this data with the output of the ocean wave model allows for the prediction of wave sequences at the target location within a specific future timeframe, including important parameters such as wave height, period, and wave direction. This helps port operators understand ocean wave conditions in advance, enabling them to make reasonable decisions regarding lock control to protect port facilities and operational safety.

[0072] Step S202: Compare the wave sequence data of the target location with the wave data threshold to obtain the wave comparison result. The wave data threshold includes: period duration threshold and wave height threshold parameters.

[0073] In this embodiment, step S102, which compares the wave sequence data of the target location with a pre-set wave data threshold, helps to identify whether the target location will face wave conditions exceeding safe limits within a predetermined future timeframe. The wave sequence data, including key parameters such as wave height, period, and wave direction, is output by the wave forecasting model and reflects the intensity and characteristics of future wave activity. The wave data threshold serves as a warning standard; if the wave parameters at the target location exceed this standard, it indicates a potential risk to the safety of port facilities and vessels.

[0074] Optionally, the wave data threshold is determined as follows: The wave simulation results of the coastal zone wave dynamics simulation model are analyzed to obtain the maximum allowable wave height and period for each berth, including wind waves and swells. The coastal zone wave dynamics simulation model is used to simulate wave propagation in the nearshore area of ​​the project area and assess the distribution of wave energy in the nearshore area. Each berth in the target sea lock project is monitored to obtain real-time wave height and period data. Based on the maximum allowable wave height and period for each berth, and the monitored real-time wave height and period data, the wave data threshold is determined.

[0075] In this embodiment, when determining the wave data threshold, a coastal wave dynamics simulation model can be used to simulate wave propagation in the nearshore area of ​​the target sea lock project, assessing the distribution pattern of wave energy in the nearshore area of ​​the project area. The simulation process helps identify the range of wave conditions that the project area may encounter. Next, the wave simulation results from the coastal wave dynamics simulation model are analyzed in depth to extract key parameters of the impact of wind waves and swells on each berth, namely the maximum allowable wave height and period for each berth. These parameters reflect the berth's tolerance limit when facing specific wave conditions.

[0076] It should be noted that this embodiment also includes monitoring real-time wave height and period data for each berth. Through the real-time monitoring system, instantaneous changes in waves can be captured to dynamically adjust the threshold. Through the collection and analysis of real-time data, it is helpful to assess the actual wave environment of the berth in a timely manner, ensuring that the setting of wave data thresholds can closely match the actual operating conditions, and improving the system's response speed and adaptability.

[0077] Finally, this embodiment comprehensively determines wave data thresholds based on the maximum allowable wave height and period for each berth under wind and swell conditions, combined with real-time monitored wave height and period data (the period duration threshold is used to determine whether the wave period indicated by the period data is a long-period wave; in the case of long-period waves, automatic gate closure is required). The aim is to find a balance point that minimizes the impact of the lock on normal operations while ensuring safety. By comparing simulation results with real-time data, this embodiment can dynamically adjust the thresholds to adapt to the constantly changing marine environment, improving the safety and efficiency of port operations.

[0078] Optionally, the steps for analyzing the wave simulation results of the coastal wave dynamics simulation model to obtain the maximum allowable wave height and period for wind waves and swells at each berth include: acquiring the boundary data and topographic data of the target sea lock project; creating a quadrilateral mesh based on the topographic data using a mesh generator to obtain a topographic mesh file; setting a sponge layer at the land boundary based on the boundary data to obtain a sponge layer file; inputting the topographic mesh file and the sponge layer file into the harbor wave model, and using the harbor wave model to analyze the wave results of the coastal wave dynamics simulation model through Fourier transform to obtain the maximum allowable wave height and period for wind waves and swells at each berth.

[0079] In this embodiment, the wave simulation results of the coastal wave dynamics simulation model are analyzed to determine the maximum allowable wave height and period for each berth. Specifically, boundary data and topographic data of the target sea lock project are first acquired. The boundary data clarifies the scope of the simulation area, while the topographic data provides detailed information on the seabed topography, including depth and slope. Then, based on the acquired topographic data, a quadrilateral mesh is created using a mesh generator to form a topographic mesh file. Meshing helps the simulation model more accurately calculate the wave propagation characteristics under different topographic conditions, improving the accuracy and reliability of the simulation.

[0080] Meanwhile, this embodiment also incorporates a sponge layer at the land boundary to absorb wave reflection at the simulated boundary, reducing the interference of boundary conditions on the simulation results. This generates a sponge layer file, ensuring more reasonable boundary conditions for wave simulation and improving the accuracy of the simulation results. Finally, the prepared terrain mesh file and sponge layer file are input into the harbor wave model. This model is used for wave propagation simulation analysis. Post-processing of the simulation results using Fourier transform allows for the separation and analysis of wave components of different wavelengths, thereby obtaining specific indicators of the impact of wind waves and swells on each berth, namely the maximum permissible wave height and period.

[0081] Optionally, the step of determining the wave data threshold based on the maximum allowed wave height and period for each berth of wind and waves and swell, as well as the monitored real-time wave height and period data, includes: adjusting the maximum allowed wave height and period for each berth of wind and waves and swell based on the monitored real-time wave height and period data, and calculating the wave data threshold for the target location point outside the engineering area based on the adjusted wave height and period.

[0082] In this embodiment, a real-time monitoring system can capture the instantaneous wave conditions in the sea area near the current berth, including key parameters such as wave height and period. This data reflects instantaneous changes in the marine environment and is crucial for assessing current and near-term wave risks. Based on the real-time monitored data, this embodiment adjusts the maximum allowable wave height and period for each berth based on wind, waves, and swells. The adjustment steps consider changes in actual wave conditions, helping to ensure that the threshold settings match the current marine environment and preventing threshold failure due to changes in conditions. The adjustment is based on a combination of real-time monitoring data and long-term statistical analysis, considering not only short-term fluctuations but also seasonal or climatic wave characteristics.

[0083] After adjusting the maximum allowable wave height and period for each berth, this embodiment continues to advance. Based on these adjusted parameters, the wave data threshold for the target location outside the engineering area is calculated. The calculation process can utilize wave physics models and ocean dynamics theories to extend the safety standards of the berths to the open sea and identify when the wave conditions at the target location may threaten the safety of the inner harbor.

[0084] By using the adjusted maximum permissible wave height and period as input, the model can predict the impact of wave activity at a target location on the safety margin of the inner harbor berths. This helps to identify potential dangerous wave conditions in advance, enabling the lock control system to take preventative measures, such as closing the gates in advance, before the waves reach the harbor basin. This reduces the impact of wave energy on harbor facilities and protects the port and vessels from damage.

[0085] Step S203: If the wave comparison result indicates that the wave sequence data is greater than the wave data threshold, a closing control signal is sent to the gate control device to close the gate within a specified time period.

[0086] If wave comparison results indicate that the wave sequence data at the target location exceeds the wave data threshold, this embodiment will send a closing control signal to the gate control equipment of the sea lock via a dedicated communication channel. This signal conveys the instruction to close the gate within the upcoming specified time period to block or mitigate the impact of long-period waves on the harbor area.

[0087] It should be noted that the selection of the specified time period can be based on the predicted duration provided by the wave forecast model and the expected duration of the peak wave activity.

[0088] Upon receiving the closure control signal, the gate control equipment can activate the hydraulic opening and closing mechanism or other corresponding closure methods to keep the gate closed for a specified period of time. This helps port operators to take timely protective measures based on the forecast wave conditions without affecting daily operations, thereby ensuring the safety of port facilities and the continuity of maintenance operations.

[0089] Step S204: If the gate is closed for a predetermined warning time, an opening control signal is sent to the gate control device to open the gate.

[0090] The gate control logic in this embodiment includes monitoring the duration of gate closure. Once it is detected that the gate has been closed according to the previous safety instructions, and this closure has lasted for a predetermined warning duration, the system will automatically send an opening control signal to the gate control equipment. The setting of the warning duration helps to avoid the impact of prolonged gate closure on normal port operations. The determination of the warning duration is based on multiple factors, including the timeliness of wave forecasts, port operational needs, and past experience data, ensuring that the gate can be opened promptly after safety conditions are restored, restoring free exchange of water between the port and the outside world, thereby protecting the port's operational efficiency from the negative impact of prolonged closure.

[0091] When the monitoring system confirms that the sea conditions meet the safety standards, i.e., are below the set wave data threshold, and the time that meets this condition is equal to or exceeds the predetermined warning duration, the system automatically triggers the sending of an activation signal without human intervention, which helps to reduce operation delays and improve response speed.

[0092] The automatic gate opening mechanism in this embodiment is designed with a focus on both safety and efficiency. From a safety perspective, the gate opening process is only initiated after the monitoring system confirms that the sea conditions meet the safety release standards. This helps mitigate potential risks and ensures the safety of personnel, facilities, and vessels within the port. From an efficiency perspective, the automatic opening mechanism reduces the time required for human judgment and operation, facilitating a rapid return to normal operations and avoiding additional waiting time caused by delays in human decision-making, thereby improving the overall operational efficiency of the port. Furthermore, this embodiment can flexibly adjust the alert duration according to different port operational needs and weather conditions, ensuring that the operational window is maximized while protecting safety, thus promoting the port's economic benefits.

[0093] Through the above steps, the topographic range data and topographic grid of the target sea lock project can be input into the wave forecasting model. The wave forecasting model, based on weather forecast data for a predetermined time period, simulates ocean waves at the target location outside the project area, outputting wave sequence data for the target location within a predetermined future time period. This wave sequence data includes at least wave height data and period data. The wave sequence data at the target location is compared with wave data thresholds to obtain a wave comparison result. These wave data thresholds include period duration thresholds and wave height thresholds. If the wave comparison result indicates that the wave sequence data is greater than the wave data threshold, a closing control signal is sent to the gate control equipment to close the gate within a specified time period. If the gate closure duration reaches a predetermined warning duration, an opening control signal is sent to the gate control equipment to open the gate. In this embodiment, by adding a sea gate at the breakwater entrance and combining it with an intelligent wave forecasting model to analyze wave sequence data of the target location within a predetermined time period, effective management of long-period waves and real-time optimization of the dock operation environment can be achieved. When a long-period wave is detected to exceed a preset threshold, the sea gate can be quickly closed to cut off the direct impact of the wave on the port area, thereby improving the safety of ship berthing and cargo loading and unloading. This solves the technical problem in related technologies where using breakwaters to block long-period waves at the dock results in the inability to eliminate the wave's impact, thus affecting the safety of ships at berths.

[0094] The following describes in detail another optional implementation method.

[0095] Figure 3 This is a schematic diagram of an optional gate control method based on a novel sea gate control system according to an embodiment of the present invention, as shown below. Figure 3 As shown, wave simulation is first performed to determine the wave-dissipating zone and berth operating conditions. Combined with real-time berth monitoring data, wave data thresholds are determined. Simultaneously, terrain parameters and the driving file are input into the PDI-WFS model to extract wave sequence data. Based on the wave data thresholds, a decision is made regarding whether to close the gate. The following section combines… Figure 1 and Figure 3 This embodiment will be described in detail.

[0096] The first step is to determine the berth control conditions.

[0097] Under long-period wave conditions, berth control conditions need to be obtained through numerical simulation analysis of specific projects. The analysis results will provide the maximum allowable wave height and period for each berth under both wind and swell conditions.

[0098] A wave model within the harbor was established based on the MIKE21BW model.

[0099] Basic data collection: This includes model boundary data collection and terrain data collection.

[0100] Terrain file creation: Based on the collected terrain data, use the Bathymetries mesh generator to create quadrilateral meshes. Sponge layer file creation: Set up sponge layers at land boundaries to absorb excess wave energy.

[0101] Results: Output the wave height at the wharf. The wave results from the BW model were analyzed using Fourier transform to separate the long-wave and short-wave results.

[0102] The second step is real-time berth monitoring.

[0103] Because berth control conditions have a certain degree of error, they need to be corrected through actual operation. The shipboard observations include: wave height and period.

[0104] The third step is to determine the threshold for wave data.

[0105] For the corrected berth operation conditions, the wave data threshold at point p outside the engineering area is calculated using the wave height relationship obtained from the numerical model: wave height + period combination.

[0106] The fourth step is wave data sequence prediction.

[0107] Optionally, this embodiment can utilize a wave forecasting model (such as the PDI-WFS model) to forecast the wave field of the engineering area for a specified period of time (e.g., within 15 days) in response to the wave demand during the construction and operation of port and waterway engineering projects. It can output the wave field time series, as well as the average wave parameters of deep water points, the wave full spectrum, and the time series of spectral partitions.

[0108] Terrain parameters: terrain extent, grid size.

[0109] Driven file: Global Atmospheric Forecast Data (GFS) (1° resolution) released by the Environmental Forecasting Center.

[0110] Output results: Output wave data for target location point P over a specified time period (e.g., three days). Output one result per hour, including wave height, period, and wave direction.

[0111] It should be noted that the wave forecasting model PDI-WFS used in this embodiment is based on the WW3 model. The core of the WW3 model system is the wave model subroutine W3WAVE. The wave model routine can be called independently by a shell program or by other programs that need to dynamically update wave data. WW3 provides two shell programs: one is a simple ww3_shel for handling single grids, and the other is ww3_multi for handling complex multi-grid systems. Auxiliary programs include a grid preprocessing program (set), a program for generating artificial initial conditions, an input data preprocessor, and an output data postprocessing program (set).

[0112] The main program routine for the wave model can be W3WAVE, and the data file is identified by the suffix .ww3. However, in the multi-grid wave model, each grid is identified by its suffix.

[0113] Input data such as wind, waves, and ice are generated into data files by the input data preprocessor. The wave model can also optionally read boundary conditions, with the boundary condition file named nest.ww3. Similarly, it is also possible to generate boundary conditions nestn.ww3.

[0114] The model writes the raw data of grid-averaged wave parameters, local spectra, spectra along the trajectory, and zoned wave data to separate output files, while the output trajectory is defined in another file. Here, the model does not directly write the standard output to a file, as this would be inconvenient when WW3 is part of an integrated model. It can output its own log file and select a test output file; for shared memory models, the file name is test.ww3, and for distributed memory models, the output file name is testnnn.ww3. Finally, there is a series of post-processors for the output data, including processing the raw grid field data, point outputs, and trajectory output data; packaging the grid wave data into GRIB data (Gridded Binary, an international standard format for storing and transmitting gridded meteorological data); and processing the grid data or spectral data into plotting data.

[0115] The fifth step is to control the opening and closing of the gate.

[0116] When the forecast data at point p outside the project area exceeds the threshold, a message is sent to the gate control equipment, and the gate is closed during the corresponding time period. Once the warning period has passed, the gate can be opened.

[0117] Through the above implementation method, by setting up a sea gate outside the engineering area entrance and combining it with precise wave data threshold determination technology, the gate can be closed in a timely manner during periods of significant long-period wave influence, effectively preventing large waves from entering the port, significantly reducing the impact of waves on the wharf and ships, and significantly improving the operational safety of port facilities and personnel safety. The sea gate control system of this invention is not static but based on real-time monitoring and dynamic forecasting technology. It can open the gate during periods when wave conditions permit, ensuring safety and avoiding unnecessary prolonged closures. This maximizes the port's operational window, improves loading and unloading efficiency, reduces ship waiting time, and lowers operating costs.

[0118] Furthermore, this embodiment can further reduce the energy of long-period waves that have entered the port by setting up wave-dissipating zones and using various wave-dissipating methods (such as boulders, slopes, and vegetation), thereby reducing the adverse effects of waves on berths and docked vessels and creating a more stable port operating environment.

[0119] This invention provides port management departments with rich data support through continuous wave data monitoring and forecasting, which helps in long-term planning and emergency preparedness, and improves the overall operation and management level.

[0120] The following is a detailed description with reference to another embodiment.
