[0070] Next, the technical solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0071] Please refer to Figures 1 to 9 , an in-navigation tide level control method for a trailing suction hopper dredger, which is applied to the in-navigation tide level control scenario of the trailing suction hopper dredger; the in-navigation tide level control method for the trailing suction hopper dredger includes:

[0072] Step S11: Collect the antenna elevation data of the trailing suction hopper dredger;

[0073] Step S12: Define the tide level data based on the antenna elevation data;

[0074] Step S13: Obtain the draft data of different positions of the trailing suction hopper dredger;

[0075] Step S14: Synchronize the tide level data and the draft data to a unified time scale;

[0076] Step S15: Collect the ship installation data and define the vertical distance according to the ship installation data;

[0077] Step S16: Define the in-navigation tide level of the trailing suction hopper dredger based on the tide level data, the draft data, and the vertical distance.

[0078] In the embodiment of the present invention, by the method of the embodiment of the present invention, the antenna elevation data of the trailing suction hopper dredger is collected; the tide level data is defined based on the antenna elevation data; the draft data at different positions of the trailing suction hopper dredger is obtained; the tide level data and the draft data are synchronized to a unified time scale, realizing the synchronization of the tide level data and the draft data in time, facilitating the further processing of the tide level data and the draft data, and ensuring the subsequent processing of the tide level data and the draft data.

[0079] Furthermore, the ship installation data is collected, and the vertical distance is defined according to the ship installation data; the in-navigation tide level of the trailing suction hopper dredger is defined based on the tide level data, the draft data, and the vertical distance, accommodating the overall consideration of the tide level data, the draft data, and the vertical distance, realizing the multi-dimensional control of the tide level data, the draft data, and the vertical distance, ensuring the accurate control of the in-navigation tide level of the trailing suction hopper dredger, and further ensuring the accuracy of the in-navigation tide level of the trailing suction hopper dredger.

[0080] Reference Figure 2 , in step S11, the antenna elevation data of the trailing suction hopper dredger is collected;

[0081] In the specific implementation process of the present invention, the specific steps may be:

[0082] S111: Locate the trailing suction hopper dredger;

[0083] S112: Associate the trailing suction hopper dredger and the satellite-based augmentation system (SBAS) high-precision positioning device;

[0084] S113: Perform dynamic interaction between the trailing suction hopper dredger and the SBAS high-precision positioning device;

[0085] S114: Collect the antenna elevation data of the trailing suction hopper dredger based on the dynamic interaction between the trailing suction hopper dredger and the SBAS high-precision positioning device.

[0086] In the embodiment of the present application, the trailing suction hopper dredger is located, the trailing suction hopper dredger is introduced, and the trailing suction hopper dredger is controlled. At the same time, the trailing suction hopper dredger and the SBAS high-precision positioning device are associated, and the overall consideration of the trailing suction hopper dredger and the SBAS high-precision positioning device is realized, achieving the multi-dimensional control of the trailing suction hopper dredger and the SBAS high-precision positioning device.

[0087] Therefore, dynamic interaction is performed between the trailing suction hopper dredger and the satellite station differential high-precision positioning device; based on the dynamic interaction between the trailing suction hopper dredger and the satellite station differential high-precision positioning device, the antenna elevation data of the trailing suction hopper dredger is collected, the antenna elevation data of the trailing suction hopper dredger is introduced, and subsequent control of the antenna elevation data of the trailing suction hopper dredger is carried out.

[0088] At this time, the satellite station differential high-precision positioning device is connected to the automation system of the trailing suction hopper dredger through a wireless network or a wired connection. During the navigation of the trailing suction hopper dredger, the satellite station differential high-precision positioning device will measure the position and height information of the ship in real time. Through the ship automation system, these data can be obtained and stored in real time, including the height of the antenna relative to the sea level or a certain reference plane. Therefore, based on the dynamic interaction between the trailing suction hopper dredger and the satellite station differential high-precision positioning device, the antenna elevation data of the trailing suction hopper dredger can be collected in real time.

[0089] Optionally, the RTX device can output a GGA format message of the NEMA0183 protocol in the phase-locked state. This message contains time information, latitude information, accuracy information, elevation information (the starting elevation based on the earth ellipsoid), satellite status information (the satellite status ranges from 1 to 4, and different statuses represent different elevation accuracies obtained), etc. The time information, elevation information, and satellite status information can be extracted from the GGA message.

[0090] Reference Figure 3 , in step S12, tidal level data is defined based on the antenna elevation data;

[0091] In the specific implementation process of the present invention, the specific steps can be:

[0092] S121: Freeze the antenna elevation data;

[0093] S122: Traverse the antenna elevation data;

[0094] S123: Define multiple position data according to the traversal of the antenna elevation data;

[0095] S124: Define tidal level data based on the identification of multiple position data.

[0096] In the embodiment of the present application, the antenna elevation data is frozen, the antenna elevation data is introduced, and then the antenna elevation data is traversed, so as to realize the traversal of the antenna elevation data.

[0097] At this time, the antenna elevation data is traversed. Traversal refers to the process of accessing the antenna elevation data one by one in a certain order (such as chronological order). Through traversal, the integrity and continuity of the data can be checked, and a basis for subsequent analysis and processing can be provided. Traverse these data in chronological order. They may write scripts using programming languages (such as Python, MATLAB, etc.), access each data point one by one through a loop structure, and check information such as the value and timestamp of the data.

[0098] During the process of traversing the antenna elevation data, multiple position data can be defined according to the characteristics of the data (such as height change, time interval, etc.). These position data usually represent the position and height information of the ship at different time points, and can be used for subsequent tide level calculation and analysis.

[0099] Furthermore, multiple position data are defined based on the traversal of the antenna elevation data; tide level data are defined based on the identification of multiple position data. The identification of multiple position data is introduced, and the control of multiple position data is carried out to ensure the accuracy of the tide level data.

[0100] At this time, after multiple position data are defined, the tide level data can be defined through the analysis and processing of these position data. The tide level data usually represents the sea water height at a specific time point and position. Optionally, engineers can use reference data such as tide tables and nautical charts, combined with the defined position data to calculate the tide level. They may look up the corresponding tide level value in the tide table according to the longitude, latitude, and time information of the position data. In addition, they can also use mathematical models (such as tide prediction models) to calculate the tide level according to the position data and time information. Finally, engineers will obtain a series of tide level data, which represent the sea water height at different time points and positions.

[0101] Reference Figure 4 , in step S13, draft data at different positions of the trailing suction hopper dredger are obtained;

[0102] In the specific implementation process of the present invention, the specific steps may be:

[0103] S131: Fix the trailing suction hopper dredger;

[0104] S132: Perform sensor detection on the trailing suction hopper dredger;

[0105] S133: Define the positions where the draft sensors are located based on the sensor detection of the trailing suction hopper dredger; at this time, the positions where the draft sensors are located are the bow, the midship, the ship position, and the dredging mouth respectively;

[0106] S134: Collect the corresponding draft sensors according to each draft sensor to define the draft data at different positions of the trailing suction hopper dredger;

[0107] S135: Dynamically obtain the draft data at different positions of the trailing suction hopper dredger.

[0108] In the embodiment of the present application, a trailing suction hopper dredger is introduced, and then sensor detection is carried out on the trailing suction hopper dredger; based on the sensor detection of the trailing suction hopper dredger, the positions where the draft sensors are located are defined; at this time, the positions where the draft sensors are located are respectively the bow, the midship, the ship position, and the dredging mouth, and an overall control is carried out on the positions where the draft sensors are located.

[0109] At this time, based on the sensor detection results of the trailing suction hopper dredger, the specific positions of the draft sensors need to be determined. The position selection of the draft sensors is crucial for accurately reflecting the draft state of the ship. Usually, these positions will be distributed at key parts of the ship to comprehensively monitor the draft changes of the ship.

[0110] Bow: The draft sensor is installed at the bow position to monitor the draft depth at the front of the ship.

[0111] Midship: Installing a draft sensor at the midship part can monitor the draft state at the middle of the ship.

[0112] Dredging mouth: Installing a draft sensor at the dredging mouth of the trailing suction hopper dredger can monitor the draft state of the dredging mouth during operation.

[0113] Therefore, according to the corresponding draft sensors collected by each draft sensor, the draft data at different positions of the suction dredger are defined; the draft data at different positions of the suction dredger are dynamically obtained, the draft data at different positions of the suction dredger are introduced, and the draft data at different positions of the suction dredger are overall controlled.

[0114] At this time, the draft sensors will collect data in real time or regularly and transmit these data to the ship's automation system or data recording equipment. Engineers or technicians can view and analyze the draft data through these systems or equipment, including the draft depth at different positions, change trends, etc.

[0115] Optionally, generally a pair of draft sensors are installed at each of the bow, midship, ship position, and dredging mouth of the trailing suction hopper dredger. The draft sensor data will enter the network switch through the gateway and be edited together with other sensor data into a ship construction data message for transmission. The draft data corresponding to each draft sensor can be read according to the ship construction data message protocol.

[0116] Reference Figure 5 , S14: Synchronize the tide level data and the draft data to a unified time scale;

[0117] In the specific implementation process of the present invention, the specific steps can be:

[0118] S141: Freeze the draft data at different positions;

[0119] S142: Collect tide level data;

[0120] S143: Associate the draft data at different positions with the tide level data;

[0121] S144: Perform time control on the draft data at different positions and the tide level data;

[0122] S145: Associate the time dimension, the draft data at different positions, and the tide level data;

[0123] S146: Synchronize the tide level data and the draft data to a unified time scale.

[0124] In the embodiment of the present application, the antenna elevation data of the trailing suction hopper dredger is collected; the tide level data is defined based on the antenna elevation data; the draft data at different positions of the trailing suction hopper dredger is obtained; the tide level data and the draft data are synchronized to a unified time scale, realizing the synchronization of the tide level data and the draft data in time, facilitating the further processing of the tide level data and the draft data, and ensuring the subsequent processing of the tide level data and the draft data.

[0125] At this time, freeze the draft data at different positions, and at the same time, collect the tide level data; associate the draft data at different positions with the tide level data, and perform overall control on the draft data at different positions and the tide level data, realizing the multi-dimensional control of the draft data at different positions and the tide level data.

[0126] At this time, associate the draft data at different positions (such as the bow, the middle of the ship, the ship position, the dredging mouth) of the trailing suction hopper dredger with the tide level data at the same time point, record the data of the draft sensor and the tide gauge, and stamp each data point with a time stamp. Whenever new draft data and tide level data are collected, they are automatically associated with the current time stamp and stored in the corresponding database table.

[0127] Therefore, perform time control on the draft data at different positions and the tide level data; associate the time dimension, the draft data at different positions, and the tide level data; synchronize the tide level data and the draft data to a unified time scale, realizing the synchronization of the tide level data and the draft data in time, facilitating the further processing of the tide level data and the draft data, and ensuring the subsequent processing of the tide level data and the draft data.

[0128] At this time, a more in-depth association of the time dimension (such as date, time) with the draft data and tide level data can be carried out. Data visualization tools (such as Excel, Tableau, etc.) can be used to create time series charts to show the changing trends of the draft data and tide level data over time. These charts can help us identify patterns, trends, and outliers in the data, ensuring that the tide level data and draft data are compared on a unified time scale. This usually means that we need to perform time synchronization processing on the data to ensure that they have the same time reference. Optionally, assume that we decide to adjust all data points to midnight (00:00) every day. In this way, regardless of the time of day when the draft data and tide level data are collected, they will be synchronized to the time scale of midnight every day. In this way, we can more easily compare and analyze this data without worrying about errors caused by time differences.

[0129] Optionally, for the tide level data output by RTX, its time stamp is GNSS (Global Navigation Satellite System) time, and for the ship draft data output by the draft sensor, its time stamp is the computer time of the ship's central server. The two are inconsistent in data collection frequency, and time synchronization technology is required to synchronize the tide level data and draft data to a unified time scale.

[0130] Reference Figure 6 , S15: Collect the ship installation data and define the vertical distance according to the ship installation data;

[0131] In the specific implementation process of the present invention, the specific steps can be:

[0132] S151: Monitor the trailing suction hopper dredger in real time;

[0133] S152: Define the ship installation data based on the real-time monitoring of the trailing suction hopper dredger;

[0134] S153: Collect the ship installation data;

[0135] S154: Analyze the ship installation data;

[0136] S155: Define the vertical distance according to the analysis of the ship installation data.

[0137] In the embodiment of the present application, the trailing suction hopper dredger is monitored in real time; the ship installation data is defined based on the real-time monitoring of the trailing suction hopper dredger, and the ship installation data is collected to facilitate the control of the ship installation data. At the same time, the ship installation data is analyzed, realizing the analysis of the ship installation data, and thus the vertical distance is defined according to the analysis of the ship installation data, ensuring the accuracy of the vertical distance.

[0138] At this time, collect all data during the ship installation process, including but not limited to the ship's dimensions (such as length overall, molded breadth, molded depth), equipment positions, installation angles, vertical and horizontal distances, etc. Preprocess the collected data, including data cleaning (removing invalid or incorrect data), data conversion (such as converting string data to numerical data), and data formatting (such as unifying data formats and units). Then parse the preprocessed data. This usually involves splitting, reorganizing, and calculating the data to extract useful information. Verify the parsed results to ensure the accuracy and integrity of the data. This can be achieved by comparing with the original data, using verification algorithms, or conducting actual measurements.

[0139] Meanwhile, during the ship installation process, one or more reference points need to be determined as the basis for measuring vertical distances. These reference points can be a certain fixed position of the ship, the foundation of the equipment, or the installation bracket, etc.; use measuring tools (such as laser rangefinders, tape measures, etc.) to measure the vertical distance from the reference point to the target position (such as the top, bottom, or other key positions of the equipment); record the measured vertical distance data and organize it. This includes classifying the data, numbering it, marking the measurement position and date, etc.

[0140] According to the parsing results of the ship installation data, further analyze and define the measured vertical distances. This may involve calibrating, correcting, or converting the data to obtain more accurate vertical distance values, and apply the parsed and defined vertical distance data to the ship installation and commissioning process. This can ensure the correct installation and positioning of the equipment and improve the performance and safety of the ship.

[0141] Reference Figure 7 , S16: Define the in - transit tide level of the trailing suction hopper dredger based on tide level data, draft data, and vertical distance;

[0142] In the specific implementation process of the present invention, the specific steps can be:

[0143] S161: Fix the vertical distance;

[0144] S162: Associate tide level data, draft data, and vertical distance;

[0145] S163: Perform dynamic interaction on tide level data, draft data, and vertical distance;

[0146] S164: Define the first in - transit tide level parameter according to tide level data and draft data;

[0147] S165: Define the second in - transit tide level parameter according to tide level data and vertical distance;

[0148] S166: Associate the first in-navigation tide level parameter, the second in-navigation tide level parameter, and the trailing suction hopper dredger, and define the in-navigation tide level of the trailing suction hopper dredger according to the first in-navigation tide level parameter, the second in-navigation tide level parameter, and the trailing suction hopper dredger.

[0149] In the specific implementation process of the present invention, ship installation data is collected, and the vertical distance is defined according to the ship installation data; based on the tide level data, draft data, and vertical distance, the in-navigation tide level of the trailing suction hopper dredger is defined, which incorporates the overall consideration of the tide level data, draft data, and vertical distance, realizes the multi-dimensional control of the tide level data, draft data, and vertical distance, ensures the precise control of the in-navigation tide level of the trailing suction hopper dredger, and further ensures the accuracy of the in-navigation tide level of the trailing suction hopper dredger.

[0150] At this time, freeze the vertical distance; associate the tide level data, draft data, and vertical distance, introduce the tide level data, draft data, and vertical distance, and conduct an overall consideration of the tide level data, draft data, and vertical distance, realizing the multi-dimensional control of the tide level data, draft data, and vertical distance.

[0151] At the same time, conduct dynamic interaction on the tide level data, draft data, and vertical distance; define the first in-navigation tide level parameter according to the tide level data and draft data; define the second in-navigation tide level parameter according to the tide level data and vertical distance; associate the first in-navigation tide level parameter, the second in-navigation tide level parameter, and the trailing suction hopper dredger, and define the in-navigation tide level of the trailing suction hopper dredger according to the first in-navigation tide level parameter, the second in-navigation tide level parameter, and the trailing suction hopper dredger, which incorporates the overall consideration of the tide level data, draft data, and vertical distance, realizes the multi-dimensional control of the tide level data, draft data, and vertical distance, ensures the precise control of the in-navigation tide level of the trailing suction hopper dredger, and further ensures the accuracy of the in-navigation tide level of the trailing suction hopper dredger.

[0152] At this time, during the ship's navigation, the tide level data, draft data, and vertical distance data are updated in real time or periodically, and these data need to be correlated and interacted with each other. Specifically, when the tide level changes, the draft depth of the ship will also be affected, and at the same time, the vertical distance between the ship and the water surface or the seabed will also change accordingly.

[0153] Regarding the first in-navigation tide level parameter, the first in-navigation tide level parameter is defined according to the tide level data and draft data, and this parameter may reflect the safe water level or operation limit of the ship under specific navigation conditions. Specifically, we can add the tide level data and the draft data, and add a safety margin (usually determined according to the ship type and navigation conditions), so as to obtain a minimum water level that ensures the safe navigation of the ship. This parameter is very important for ship operators because it can help them evaluate navigation safety, formulate navigation plans, and avoid dangerous situations such as running aground or colliding.

[0154] For the second in-navigation tide level parameter, the second in-navigation tide level parameter is defined based on the tide level data and the vertical distance. This parameter pays more attention to the vertical relationship between the ship and the water surface or the seabed to ensure that the ship does not collide with obstacles or run aground during navigation. Specifically, we can compare the tide level data with the minimum vertical distance between the ship and the obstacle (determined according to the ship type and navigation conditions) to obtain a maximum tide level limit to ensure the safe navigation of the ship. When the tide level exceeds this limit, the ship's operator needs to take corresponding measures to avoid dangerous situations.

[0155] Integrate these parameters to define the actual tide level of the trailing suction hopper dredger during navigation. Specifically, we can use the two in-navigation tide level parameters as the limiting conditions for the safe navigation of the ship, and formulate a navigation plan, adjust the navigation attitude, and take corresponding safety measures based on these conditions. For example, when the tide level approaches or exceeds the second in-navigation tide level parameter, the ship's operator may need to reduce the speed, adjust the course, or choose other safe navigation routes to avoid dangerous situations such as collisions or groundings.

[0156] Optionally, assume that a trailing suction hopper dredger is operating in a certain sea area, with a draft of 6 meters and a minimum vertical distance of 3 meters from the seabed. At the same time, the tide level data in this sea area shows that the current tide level is 2 meters, and with the tide change, the tide level will fluctuate between -1 meter and 3 meters.

[0157] The first in-navigation tide level parameter: Considering the ship's draft and safety margin (assumed to be 1 meter), we can obtain that the safe water level of the ship at the lowest tide level (-1 meter) is 7 meters (draft 6 meters + safety margin 1 meter). Therefore, when the tide level is lower than 7 meters, the ship may face the risk of running aground.

[0158] The second in-navigation tide level parameter: Considering the minimum vertical distance between the ship and the seabed (3 meters), we can obtain that the maximum safe tide level limit of the ship at the highest tide level (3 meters) is 6 meters (the original minimum vertical distance 3 meters - the reduction in the tide level rise of 3 meters). This means that when the tide level exceeds 6 meters, the vertical distance between the ship and the seabed will be less than 3 meters, and there may be a risk of collision.

[0159] Optionally, the vertical distance Tide from the sea surface to the tide reference level is the in-navigation tide level value of the ship; H1 is the elevation data measured by the RTX device, H2 is the ship draft data measured by the draft sensor, and D is the vertical distance from the RTX device to the draft sensor device (which can be obtained from the ship installation data). Then the in-navigation tide level data Tide of the ship can be calculated by the following formula:

[0160] Tide = H1 - D + H2
