Description

Technical Field

[0001] The present invention relates to the technical field of ship construction, and particularly to a method, device, equipment and medium for adjusting the excavation depth of a ship. Background Art

[0002] With the rapid development of global infrastructure construction and ocean engineering, ship dredging construction has gradually become an important means to achieve water depth regulation and port construction. The ship dredging construction technology mainly controls the dredging depth during the construction process to ensure that the ship can operate smoothly in a complex water area environment and avoid safety accidents such as grounding and capsizing. However, traditional ship dredging construction methods usually rely on static environmental parameters, ignoring the dynamic changes of the water area environment and the mutual influence between ship performance and the environment, resulting in a reduction in construction efficiency. Summary of the Invention

[0003] In order to improve construction efficiency, the present application provides a method, device, equipment and medium for adjusting the excavation depth of a ship.

[0004] The first invention object of the present application is achieved by the following technical solutions: A method for adjusting the excavation depth of a ship, the method for adjusting the excavation depth of the ship comprising: Obtaining the water depth information of the construction area, and based on the water depth information, drawing a water depth change trend chart of the construction area; Obtaining the tidal law information of the construction area, and based on the tidal law information, drawing a tidal level change curve graph; Based on the water depth change trend chart and the tidal level change curve graph, and combining with the ship performance parameter information, calculating the preliminary excavation depth information; Obtaining the geological information of the construction area of the construction area, and based on the geological information of the construction area, using a soil-sediment characteristic analysis model to adjust the preliminary excavation depth information to obtain the adjusted excavation depth information; Constructing the construction area according to the adjusted excavation depth information.

[0005] By adopting the above technical solutions, the water depth changes, tidal patterns, and geological characteristics of the construction area are monitored in real time to ensure accurate calculation and adjustment of the excavation depth. Through the combination of the water depth change trend chart and the tidal level change curve chart, the dredging operation of the ship can be dynamically adjusted to avoid excavation depth deviation caused by water depth changes or tidal fluctuations, thereby improving the stability and safety of the construction process. At the same time, by using the ship performance parameter information, such as draft depth, load capacity, and navigation speed, etc., the excavation depth calculation is further optimized to ensure the stable operation of the ship at different construction stages. By using the soil-sediment characteristic analysis model to adjust the preliminary excavation depth, the geological characteristics of the construction area can be accurately adapted to avoid excavation errors caused by soil differences or sediment layers, thereby improving the construction accuracy and efficiency.

[0006] In a preferred example, the present application can be further configured as: obtaining the water depth information of the construction area, and based on the water depth information, drawing the water depth change trend chart of the construction area, including: Classify and organize the water depth information by time to obtain the water depth value sequence at each location; Perform smoothing processing on the water depth value sequence at each location by spline interpolation method to obtain the smoothed water depth information after spline interpolation, and based on the smoothed water depth information after spline interpolation, draw the water depth change trend chart of the construction area.

[0007] By adopting the above technical solutions, classifying and organizing the water depth information by time can ensure that the water depth changes at each location are carefully tracked, providing reliable basic data for subsequent analysis and decision-making. Then, use the spline interpolation method to smooth the water depth value sequence at each location, which not only eliminates the volatility in the measurement data but also effectively improves the smoothness and accuracy of the data, thus reducing the errors caused by irregular water depth changes. Based on the smoothed water depth information, the water depth change trend chart of the construction area can be drawn to help construction personnel grasp the law of water depth changes in real time.

[0008] In a preferred example, the present application can be further configured as: obtaining the tidal pattern information of the construction area, and based on the tidal pattern information, drawing the tidal level change curve chart, including: Obtain the tidal pattern information, standardize the tidal pattern information at a preset time interval to obtain the tidal level time series information; Use the trend analysis algorithm to calculate the tidal level time series information, calculate the tidal level change trend result, and based on the tidal level change trend result, draw the tidal level change curve chart by a graphical method.

[0009] By adopting the above technical solution, the tidal law information can be accurately obtained, and through standardized processing, the tide level time series information can be compared consistently within the same time interval, ensuring the accuracy and reliability of the data. The trend analysis algorithm is used to calculate the tide level time series, effectively revealing the long-term trend of the tide level change, thus avoiding the influence of the tide level fluctuation on the construction process and providing a better scientific basis for the subsequent construction. The tide level change curve is presented in a graphical way, enabling the construction personnel to intuitively understand the change trend of the tide level.

[0010] In a preferred example of the present application, it can be further configured as follows: based on the water depth change trend graph and the tide level change curve graph, combined with the ship performance parameter information, calculate the preliminary excavation depth information, including: Obtain the ship draft depth parameter information, ship load capacity parameter information, and ship sailing speed parameter information from the ship performance parameter information; Calculate the preliminary excavation depth information based on the following formula: D 0 (t) = (H trend(t) - T trend(t) ) - H s + f(L s , V s ), where the H trend(t) is the water depth change trend graph, the T trend(t) is the tide level change curve graph, the H s is the draft depth parameter information, the L s is the ship load capacity parameter information, the V s is the ship sailing speed parameter information, and f(Ls, Vs) is an adjustment function according to the ship load capacity parameter information and the ship sailing speed parameter information.

[0011] By adopting the above technical solution, by combining the water depth change trend graph and the tide level change curve graph and calculating using the formula, the influence of dynamic environmental factors can be considered, making the excavation depth more accurate. This solution further optimizes the calculation process of the preliminary excavation depth by the adjustment function f(Ls, Vs) in combination with the load capacity and sailing speed of the ship, ensuring that the calculation result is more in line with the actual construction requirements. This can effectively reduce the risks caused by inaccurate calculation of the excavation depth during the construction process and improve the construction efficiency and safety.

[0012] In a preferred example of the present application, it can be further configured as follows: obtain the geological information of the construction area of the construction area, and based on the geological information of the construction area, use the soil - sediment characteristic analysis model to adjust the preliminary excavation depth information to obtain the adjusted excavation depth information, including: Obtain the soil type information, sediment layer thickness information, soil moisture information, and soil density information of the construction area from the geological information of the construction area; Obtain the adjusted excavation depth information through the following formula: D adj =D 0 ·(1 + k soil (T soil ) + k sediment (H sediment , ρ soil ) + k moisture (M soil ))), where D 0 is the preliminary excavation depth information, T soil is the soil type information of the construction area, k soil is the correction coefficient of the soil, H sediment is the sediment layer thickness information of the construction area, k sediment is the sediment layer correction coefficient, ρ soil is the soil density information of the construction area, M soil is the soil moisture information of the construction area, k moisture is the soil moisture correction coefficient, and D adj is the adjusted excavation depth information.

[0013] By adopting the above technical solution, by obtaining the soil type, sediment layer thickness, soil moisture, and soil density information of the construction area and calculating in combination with the corresponding correction coefficients, the preliminary excavation depth information can be effectively corrected. This adjustment takes into account the characteristics of different soil types and sediment layers, ensuring the adaptability and safety of the excavation depth in the actual construction environment. The adjusted excavation depth information obtained through precise calculation can provide more accurate depth guidance for construction, thereby optimizing the construction path and avoiding resource waste or construction obstacles caused by inappropriate depth. In addition, this dynamic adjustment mechanism can cope with the possible geological environment changes during the construction process, reducing the impact of uncertain factors on the construction progress and quality.

[0014] In a preferred example of the present application, it can be further configured as: the dynamic control method for ship excavation depth construction further includes: during the construction process, real-time monitor the environmental information of the construction area, compare the environmental information of the construction area with the construction safety benchmark, and obtain the safety status assessment result; According to the safety status assessment result, if the environmental information of the construction area meets the construction safety benchmark, continue the construction; if the environmental information of the construction area does not meet the construction safety benchmark, generate construction adjustment information; Based on the construction adjustment information, adjust the construction dynamic parameter information. After the adjustment is completed, obtain the construction progress information, and generate a construction progress report according to the construction progress information.

[0015] By adopting the above technical solution, it is possible to monitor the environmental changes in the construction area in real time, compare them with the construction safety benchmark, and timely evaluate the safety status of the construction area. If the environmental information of the construction area meets the safety benchmark, the construction will continue. If it does not meet the safety standard, the system will generate construction adjustment information to help the on-site staff adjust the construction plan in time and avoid potential safety risks. Through this dynamic safety monitoring and adjustment mechanism, the safety and efficiency of the construction process can be ensured. In addition, the adjustment of the construction dynamic parameters can ensure that the construction progress is consistent with the changes in environmental conditions, thereby optimizing the utilization of resources and improving construction efficiency.

[0016] In a preferred example of the present application, it can be further configured that: the adjusting the construction dynamic parameter information based on the construction adjustment information includes: Obtain the construction dynamic parameter information to be adjusted from the construction adjustment information, and adjust the construction dynamic parameter information to be adjusted through the construction optimization rule; The construction optimization rule is adjusted through the following formula: P adj = f(P current , ΔP, R opt ), where Padj is the adjusted construction dynamic parameter information, P current is the current construction dynamic parameter information, ΔP is the adjustment amount of the construction dynamic parameter, and R opt is the construction optimization rule.

[0017] By adopting the above technical solution, it is possible to obtain the construction dynamic parameter information to be adjusted according to the construction adjustment information, and effectively adjust these parameters through the construction optimization rule. Through the provided formula, the construction dynamic parameter information will be adjusted based on the current construction status and optimization rule to ensure that the construction process can be carried out under the conditions that meet the environmental conditions and safety requirements. For example, the adjusted construction dynamic parameter information can reflect the impact of environmental changes on the construction process in real time, thereby ensuring the balance between construction efficiency and safety. The introduction of the construction optimization rule makes the dynamic adjustment in the construction process more scientific and accurate, improving the flexibility and adaptability of the construction process. The implementation of this solution helps to reduce resource waste and construction delays caused by environmental changes during the construction process, and improve the construction progress and quality.

[0018] The above second invention object of the present application is achieved through the following technical solution: A ship excavation depth adjustment device, the ship excavation depth adjustment device includes: A water depth change trend analysis module, which is used to obtain the water depth information of the construction area and draw a water depth change trend chart of the construction area based on the water depth information; A tide level change curve drawing module, which is used to obtain the tidal law information of the construction area and draw a tide level change curve chart based on the tidal law information; A preliminary excavation depth calculation module, which is used to calculate preliminary excavation depth information based on the water depth change trend chart and the tide level change curve chart, in combination with ship performance parameter information; A soil - sediment property analysis module, which is used to obtain the geological information of the construction area of the construction area and adjust the preliminary excavation depth information using a soil - sediment property analysis model based on the geological information of the construction area to obtain adjusted excavation depth information; A construction execution module, which is used to perform construction on the construction area according to the adjusted excavation depth information.

[0019] By adopting the above - mentioned technical solution, the water depth change, tidal law and geological characteristics of the construction area are monitored in real time to ensure the accurate calculation and adjustment of the excavation depth. By combining the water depth change trend chart and the tide level change curve chart, the dredging operation of the ship can be dynamically adjusted to avoid excavation depth deviation caused by water depth change or tidal fluctuation, thereby improving the stability and safety of the construction process. At the same time, by using ship performance parameter information, such as draft depth, load capacity and navigation speed, etc., the calculation of the excavation depth is further optimized to ensure the stable operation of the ship in different construction stages. By using a soil - sediment property analysis model to adjust the preliminary excavation depth, it can accurately adapt to the geological characteristics of the construction area and avoid excavation errors caused by soil quality differences or sediment layers, thereby improving the construction accuracy and efficiency.

By combining the water depth change trend chart and the tidal level change curve, the dredging operation of the ship can be dynamically adjusted to avoid excavation depth deviation caused by water depth changes or tidal fluctuations, thereby improving the stability and safety of the construction process. At the same time, using the ship's performance parameter information, such as draft depth, load capacity, and navigation speed, etc., further optimize the excavation depth calculation to ensure the stable operation of the ship at different construction stages.

This adjustment takes into account the characteristics of different soil types and sediment layers to ensure the adaptability and safety of the excavation depth in the actual construction environment. The adjusted excavation depth information obtained through accurate calculation can provide more accurate depth guidance for the construction, thereby optimizing the construction path and avoiding resource waste or construction obstacles caused by inappropriate depth. In addition, this dynamic adjustment mechanism can cope with the possible geological environment changes during the construction process and reduce the impact of uncertain factors on the construction progress and quality; 3. It can obtain the construction dynamic parameter information to be adjusted according to the construction adjustment information and effectively adjust these parameters through the construction optimization rules.

Detailed implementation manners

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] In one embodiment, as Figure 1 shown, the present application discloses a ship excavation depth adjustment method, which specifically includes the following steps: S10: Obtain the water depth information of the construction area, and based on the water depth information, draw a water depth change trend chart of the construction area.

[0026] Specifically, through a water depth detection device such as a multi-beam sonar or a single-beam sonar, the water depth information of the construction area is collected. The multi-beam sonar can measure the water depth at multiple measurement points simultaneously, improving the information collection efficiency, especially in a large-scale construction area. The measurement information will record the water depth value of each measurement point and correspond one-to-one with the corresponding geographical location (GPS coordinates) to ensure the accuracy of the information. By setting a reasonable measurement interval, the density and accuracy of the water depth information can be ensured. After the information collection is completed, the original water depth information is cleaned by using information processing software to remove noise and outliers, and the information is smoothed by spline interpolation method to ensure the continuity and stability of the water depth information. After the information cleaning and interpolation are completed, a water depth change trend chart of the construction area is drawn based on the processed water depth information.

[0027] S20: Obtain the tidal law information of the construction area, and based on the tidal law information, draw a tidal level change curve graph.

[0028] Specifically, tidal level information is collected in real time within a certain time range through tidal level measurement devices (such as tide gauges, buoys, etc.) installed in the construction area. These devices record tidal level information at set time intervals and transmit this information to the information processing system. In addition, historical tidal information for this area can be obtained from offshore marine meteorological stations or relevant institutions. After the tidal level information is collected, standardization processing is required, that is, by adjusting the units and time formats of different tidal levels, it is unified into a form convenient for analysis. Then, trend analysis algorithms (such as linear regression, Fourier analysis, etc.) are used to process the tidal level time series and calculate the trend of tidal level changes. According to the analysis results, a tidal level change curve graph is generated.

[0029] Furthermore, the information processing system refers to a system used to receive, store, analyze, and process information from the construction area, environmental monitoring devices, and other relevant information sources. It can collect and integrate in real time the environmental information, tidal information, geological information, etc. of the construction area, and use information analysis algorithms to process this information to provide construction decision-making support and ensure the safety and efficiency of the construction process. The information processing system is also responsible for transmitting the processed information to other relevant systems or platforms for subsequent monitoring and control operations.

[0030] S30: Based on the water depth change trend graph and the tidal level change curve graph, combined with the ship performance parameter information, calculate the preliminary excavation depth information.

[0031] Specifically, first, the performance parameters of the ship need to be obtained from the ship's monitoring system or manually input, including the draft depth, load capacity, and navigation speed of the ship. These parameters can be collected through the ship's sensors, such as draft depth sensors, load sensors, speed sensors, etc., or directly obtained from the ship's technical manual. After obtaining the ship performance information, it is necessary to combine the water depth change trend graph and the tidal level change curve graph and calculate the preliminary excavation depth through specific calculation formulas.

[0032] S40: Obtain the geological information of the construction area. Based on the geological information of the construction area, use the soil-sediment characteristic analysis model to adjust the preliminary excavation depth information to obtain the adjusted excavation depth information.

[0033] Specifically, the geological information of the construction area is usually obtained through means such as underground drilling, geological exploration, and soil sampling. During the drilling process, information such as the soil type, soil moisture, soil density, and the thickness of sediment layers at different depths is recorded, and this information is obtained through on-site experimental analysis or laboratory analysis. In addition, factors such as the particle size of the sediment layer and the friction coefficient of the soil may also affect the excavation depth. After obtaining the geological information, it is input into the soil-sediment characteristic analysis model, and the model will adjust the preliminary excavation depth based on this information. For example, if the soil density in a certain area is relatively large or the sediment layer is relatively thick, the model will consider increasing the excavation depth to ensure the construction progress and quality. On the contrary, in areas with higher soil moisture and softer sediment, the excavation depth may need to be appropriately reduced.

[0034] S50: Perform construction on the construction area according to the adjusted excavation depth information.

[0035] Specifically, the construction personnel start the construction process according to the adjusted excavation depth information. First, the construction area will be delimited according to the adjusted excavation depth, and the actual excavation depth of each position will be marked. The construction personnel use professional excavation equipment, such as excavation ships, dredgers, etc., to perform precise excavation according to the measurement results. During the construction process, real-time monitoring equipment (such as water depth detectors, laser rangefinders, etc.) is used to continuously detect the actual excavation depth and compare it with the preset depth target. The real-time monitoring information will be continuously fed back to the construction personnel to ensure that the excavation operation is carried out within the accurate depth range. If it is found that the excavation depth deviates from the designed depth, the construction personnel will adjust the operation parameters according to the real-time information to ensure that the construction depth meets the design requirements.

[0036] In one embodiment, as Figure 2 shown, in step S10, that is, obtaining the water depth information of the construction area, based on the water depth information, a water depth change trend chart of the construction area is drawn, including: S101: Classify and organize the water depth information by time to obtain a sequence of water depth values at each position.

[0037] Specifically, first, obtain the water depth information of each measurement point in the construction area. Usually, this information is collected by marine exploration instruments (such as multibeam sonar equipment) at different time periods. To ensure the comprehensiveness and accuracy of the data, the data collection process may need to be repeated multiple times, and the time interval should consider the tidal law and the change of the construction cycle. Then, classify and organize all the collected water depth information by time to ensure that the water depth information of each measurement position forms a time series.

[0038] S102: Smooth the water depth value sequence at each location through spline interpolation method to obtain the smoothed water depth information after spline interpolation. Based on the smoothed water depth information after spline interpolation, draw the water depth change trend graph of the construction area.

[0039] Specifically, for the water depth value sequence at each location, perform smoothing through the spline interpolation method. The spline interpolation method can effectively eliminate the noise and irregular fluctuations in the original data, ensuring that the water depth information curve at each location is smoother and more continuous. During the processing, the spline interpolation method usually selects appropriate interpolation nodes for data fitting according to the distribution of water depth data points, making the description of water depth changes more accurate and stable. After smoothing, the obtained smoothed water depth information will provide a more reliable basis for subsequent construction decisions. Then, based on this smoothed water depth information, use a graphical drawing tool to draw the water depth change trend graph of the entire construction area.

[0040] In one embodiment, as Figure 3 shown, in step S20, that is, obtain the tidal law information of the construction area. Based on the tidal law information, draw the tidal level change curve graph, including: S201: Obtain the tidal law information and standardize the tidal law information at a preset time interval to obtain the tidal level time series information.

[0041] Specifically, obtain the tidal law information of the construction area. The tidal law information can be obtained through a tidal prediction system, a marine observation station or other relevant devices. The tidal law information usually includes data such as the rising and falling times of the tide, the high tide level, and the low tide level. Then, standardize these data at a preset time interval (such as every hour, every minute, etc.). The standardization steps include aligning the time nodes in the tidal information to the same time interval. For example, if the original data has different recording times, unify the tidal law information to the same time period through interpolation or sampling methods. Finally, obtain a tidal level time series information evenly distributed at the time interval.

[0042] Furthermore, the tidal prediction system is used to collect and analyze the tidal law information of the construction area. Based on historical tidal information and meteorological information, use a tidal prediction model to calculate and predict the change trend of the tidal level in the future for a period of time.

[0043] S202: Use a trend analysis algorithm to calculate the tidal level time series information, calculate the tidal level change trend result, and draw the tidal level change curve graph through a graphical method based on the tidal level change trend result.

[0044] Specifically, by obtaining tidal law information, the water level data corresponding to each time point in the time series is obtained, and the data is standardized at a preset time interval to ensure that each data point in the time series has a consistent time interval and unit, which can better analyze the trend of water level changes. After standardization, a trend analysis algorithm is used to process the water level time series. Common algorithms include exponential smoothing method, ARIMA model or linear regression, etc. For data with obvious seasonal and periodic fluctuations, the exponential smoothing method can be selected. This method predicts the future trend of water level changes by weighted averaging the past water level data and assigning higher weights to the more recent time points. If the data of water level changes has obvious time dependence and trend, the ARIMA model can be used. By performing autoregressive analysis on the time series, the trends and seasonal characteristics in the data are extracted, and then predictions are made. After calculating the trend of water level changes using these algorithms, based on the calculated results of the trend of water level changes, it can be displayed by graphical methods. Common graphical methods include plotting a water level change curve graph. In this process, with the time axis as the abscissa and the water level as the ordinate, the standardized water level change data points are connected into a curve to show the trend of water level changes over time.

[0045] In one embodiment, as Figure 4 shown, in step S30, that is, based on the water depth change trend graph and the water level change curve graph, combined with the ship performance parameter information, the preliminary excavation depth information is calculated, including: S301: Obtain the ship draft depth parameter information, ship load capacity parameter information, and ship sailing speed parameter information from the ship performance parameter information.

[0046] Specifically, the draft depth, load capacity, and sailing speed of the ship are important factors affecting the excavation depth. First, by obtaining the real-time performance parameters of the ship, this information can be read through the ship's sensors or control systems. Specifically, the ship draft depth (H s ) refers to the vertical distance from the water surface to the bottom of the ship and can be obtained through a water level sensor and a measuring device at the bottom of the hull. The ship load capacity (L s ) refers to the maximum weight that the ship can safely carry and can usually be obtained from the ship's design specifications and real-time sensors (such as cargo scales, load monitoring devices). The ship sailing speed (V s ) can be obtained through the ship's speedometer or navigation system.

[0047] S302: Calculate the preliminary excavation depth information based on the following formula: D 0 (t) = (H trend(t) - T trend(t) ) - H s+f(L s , V s ), where H trend(t) is the water depth change trend graph, T trend(t) is the tidal level change curve graph, H s is the draft depth parameter information, L s is the ship load capacity parameter information, V s is the ship navigation speed parameter information, and f(Ls, Vs) is an adjustment function based on the ship load capacity parameter information and the ship navigation speed parameter information.

[0048] Specifically, based on the input of the water depth change trend graph (H trend(t) ) and the tidal level change curve graph (T trend(t) ), the physical model can be used in combination with the ship performance parameters to calculate the excavation depth. First, the water depth change trend graph provides the water depth change information in the construction area at different time points, while the tidal level change curve graph reflects the tidal level change caused by tides, and they jointly determine the current water depth condition. Then, by combining the draft depth (H s ), load capacity (L s ) and navigation speed (V s ) of the ship, the original water depth data can be adjusted to calculate the most appropriate preliminary excavation depth. In this process, the function f(L s , V s ) plays a key role. It is an adjustment function calculated based on the ship load capacity and navigation speed parameters, aiming to reflect how the ship affects the actual height of the bottom of the ship under different loads. Especially when sailing at high speed, the draft depth of the bottom of the ship will be affected by factors such as buoyancy and waves. By introducing L s and V s into this adjustment function, the influence of ship load and speed on the underwater operation depth can be comprehensively considered, so as to obtain the preliminary excavation depth information that meets the actual operation conditions. For example, if the ship load is light and the speed is high, then after being adjusted by the function f(L s , V s ), the preliminary excavation depth may be reduced because the hydrodynamic force generated by the hull during fast sailing will slightly lift the hull. And if the load is large or the speed is slow, the draft depth of the hull may increase, thus requiring a deeper excavation depth. The preliminary excavation depth information obtained through this calculation formula will be used as the basis for subsequent adjustment and construction decisions.

[0049] In an embodiment, as shown in Figure 5 , in step S40, that is, obtaining the geological information of the construction area of the construction area, based on the geological information of the construction area, using the soil - sediment characteristic analysis model to adjust the preliminary excavation depth information to obtain the adjusted excavation depth information, including: S401: Obtain the soil type information, sediment layer thickness information, soil moisture information, and soil density information of the construction area from the geological information of the construction area.

[0050] Specifically, the soil type information (T soil ) can be obtained through geological exploration or on-site soil sampling. Generally, methods such as drilling, geological section analysis, and soil classification are used to determine the soil type, such as clay, sand, or gravel. The engineering properties of each soil type are different, which affects the adjustment of the excavation depth. The sediment layer thickness information (H sediment ) is measured by geological survey equipment (such as a stratigraphic detector, ground penetrating radar, etc.). This information helps to judge the thickness and hardness of the soil layer and determines whether further soil treatment is required. The soil moisture information (M soil ) is obtained through methods such as humidity sensors and soil sampling. The moisture of the soil affects the bearing capacity and excavation difficulty of the soil. Moist soil may be easier to excavate than dry soil. The soil density information (ρ soil ) is obtained through means such as laboratory analysis and on-site sampling. The soil density also has a greater impact on the excavation depth. Soils with a higher density are harder and require a greater excavation force and depth.

[0051] S402: Obtain the adjusted excavation depth information through the following formula: D adj = D 0 ·(1 + k soil (T soil ) + k sediment (H sediment , ρ soil ) + k moisture (M soil ))), where D 0 is the preliminary excavation depth information, T soil is the soil type information of the construction area, k soil is the correction coefficient of the soil, H sediment is the sediment layer thickness information of the construction area, k sediment is the sediment layer correction coefficient, ρ soil is the soil density information of the construction area, M soil is the soil moisture information of the construction area, k moisture is the soil moisture correction coefficient, and D adj is the adjusted excavation depth information.

[0052] Specifically, based on the various parameters obtained from the geological information, the preliminary excavation depth information is adjusted through a soil-sediment characteristic analysis model. In the actual calculation process, first, from the preliminary excavation depth information (D 0) Starting from this value, which is the preliminary result calculated based on water depth, tide level, and ship performance parameters. Then, according to the soil type (T soil ) information in the construction area, select the appropriate soil correction coefficient (k soil ), which reflects the impact of different soil types on excavation. For example, clay may be more difficult to excavate than sand, so a larger correction coefficient is required. Next, according to the thickness (H sediment ) of the sediment layer in the construction area, select the corresponding sediment correction coefficient (k sediment ). If the sediment layer is thick, the excavation depth may need to be adjusted to adapt to the characteristics of the sediment layer. In addition, the density (ρ soil ) and humidity (M soil ) information of the soil will also affect the excavation depth. When the soil density is large, a deeper depth may be required for excavation, so the density correction coefficient (k soil ) will adjust the preliminary depth. The soil humidity (M soil ) is adjusted through the humidity correction coefficient (k moisture ). Soils with higher humidity may make excavation more difficult, so soils with higher humidity will require a deeper excavation depth. After combining all these adjustment coefficients and parameters and performing formula calculations, the obtained D adj is the final excavation depth information after correction.

[0053] In one embodiment, as Figure 6 shown, after step S50, that is, the ship excavation depth adjustment method, further includes: S60: During the construction process, real-time monitor the environmental information of the construction area, compare the environmental information of the construction area with the construction safety benchmark, and obtain the safety status assessment result.

[0054] Specifically, in the construction area, multiple high-precision sensors (such as water level sensors, anemometers, barometers, soil humidity detectors, etc.) are arranged for real-time monitoring of environmental information. Each sensor will upload information to the central monitoring platform regularly (such as every minute or every second) according to its type and detection range. The central monitoring platform uses an information transmission protocol (such as MQTT or HTTP) to receive information in real time. The central monitoring platform compares the collected environmental information (such as wind speed, water depth, air pressure, temperature, etc.) with the preset safety benchmark. The safety benchmark can be the standard values such as the maximum wind speed, maximum water depth, and minimum soil density set in the construction standard. The central monitoring platform will automatically judge whether the environmental information exceeds these safety benchmarks. If the environmental information meets the safety standard, it is marked as a safe state; if not, it is marked as a potential risk and an alarm is triggered.

[0055] Furthermore, the central monitoring platform is used to centrally monitor and analyze various real-time environmental information during the construction process. This platform integrates information from multiple sensors or monitoring devices, such as water depth, soil moisture, climatic conditions, etc., and can display the safety status of the construction area in real time and respond to the dynamic changes at the construction site.

[0056] S70: According to the safety status assessment result, if the environmental information of the construction area meets the construction safety benchmark, continue the construction; if the environmental information of the construction area does not meet the construction safety benchmark, generate construction adjustment information.

[0057] Specifically, when the real-time monitored environmental information conforms to the safety benchmark, the central monitoring platform sends a safety status confirmation signal to the on-site construction personnel, allowing the construction to continue and updating the construction progress information in real time. If the environmental information does not conform to the safety benchmark (such as too high wind speed, excessive water depth, etc.), the central monitoring platform will immediately activate the abnormal response mechanism, automatically generate a construction adjustment information, and propose adjustment measures according to the environmental changes. For example, if the wind speed exceeds the standard, the operating parameters of the high-altitude operation will be automatically adjusted; if the water depth is too deep, the deep-water operation will be temporarily stopped, and it is recommended to replace the construction equipment or adjust the construction depth.

[0058] S80: Based on the construction adjustment information, adjust the construction dynamic parameter information. After the adjustment is completed, obtain the construction progress information, and generate a construction progress report according to the construction progress information.

[0059] Specifically, the construction adjustment information will be transmitted to the on-site construction management personnel or the construction command central monitoring platform, and the construction team will adjust the operating parameters according to this information. For example, if the construction equipment cannot operate safely due to too high wind speed, the operator will reduce the operating speed according to the adjustment information provided by the central monitoring platform, or enable equipment with higher wind resistance. If the soil moisture is not suitable for the current operation, the depth and path of the operation may be adjusted, or some non-urgent operations may be suspended. After the adjustment is completed, the central monitoring platform will calculate the new construction progress according to the actual construction progress. The central monitoring platform will re-estimate the remaining construction time, resource usage, etc., and the progress data will be updated and displayed on the construction progress interface in real time. Finally, the central monitoring platform generates a construction progress report, which includes a comparison chart of the original progress and the actual progress, details the construction tasks and adjustment parameters adjusted due to environmental changes, and summarizes the changes and impacts of the overall construction status.

[0060] In one embodiment, as Figure 8 shown, in step S80, that is, based on the construction adjustment information, adjust the construction dynamic parameter information, including: S801: Obtain the construction dynamic parameter information to be adjusted from the construction adjustment information, and adjust the construction dynamic parameter information to be adjusted through the construction optimization rules.

[0061] Specifically, when the environmental information during construction does not conform to the safety criteria, the central monitoring platform generates construction adjustment information according to the preset construction adjustment rules. These information include the construction dynamic parameters that need to be adjusted, such as construction depth, operation speed, equipment operation parameters, etc. The construction dynamic parameter information is extracted and sorted. For example, if the soil humidity in the construction area is too high, the central monitoring platform will mark the operation depth and operation path that need to be adjusted. If the wind speed is too high, the operation speed and construction operation period will be adjusted. These parameters to be adjusted are transmitted to the central control central monitoring platform, and the central monitoring platform processes them according to the construction optimization rules. The optimization rules are based on historical data, engineering experience, and real-time feedback of the construction environment to design a suitable dynamic parameter adjustment plan to ensure construction safety and efficiency.

[0062] S802: The construction optimization rules are adjusted through the following formula: P adj = f(P current , ΔP, R opt ), where P adj is the adjusted construction dynamic parameter information, P current is the current construction dynamic parameter information, ΔP is the adjustment amount of the construction dynamic parameter, and R opt is the construction optimization rule.

[0063] Specifically, P adj is the adjusted construction dynamic parameter, representing the parameter value that meets the new construction conditions after adjustment. P current is the current construction dynamic parameter, representing the parameter value used in the current construction process without adjustment. ΔP is the adjustment amount of the construction dynamic parameter, representing the increase or decrease range required for the current parameter to meet the construction safety and efficiency requirements. R opt is the construction optimization rule, representing a set of adjustment formulas generated based on the actual construction situation, historical data, and real-time environmental conditions. These rules take into account factors such as safety criteria, construction cycle, environmental data, etc., such as relevant environmental parameters like soil humidity, wind speed, air pressure, etc. The optimization rule R opt will automatically update and calculate a new adjustment amount (ΔP) according to changes in the construction environment (such as wind speed, humidity, soil density, etc.). For example, if the current wind speed reaches the upper limit of the construction safety criteria, R opt may calculate an adjustment amount to reduce the operation speed to avoid construction risks caused by excessive wind speed. If the soil humidity is high, it may be required to adjust the operation depth to avoid mechanical damage or unstable operation. According to the calculated ΔP, apply ΔP to P current to obtain the adjusted construction dynamic parameter P adjIf multiple parameters need to be adjusted, all adjustment amounts will be calculated simultaneously and applied one by one to ensure that each parameter is optimized within a safe range. Assume that the current operation depth is P current = 5 meters, and the construction optimization rule calculates the adjustment amount as ΔP = -0.5 meters, that is, the operation depth should be reduced by 0.5 meters, and the new adjusted operation depth is P adj = 4.5 meters.
