Description

Technical Field

[0001] This invention relates to the field of ship digital twin technology or other related fields. Specifically, it relates to a ship navigation simulation method and device, and electronic equipment based on a digital twin system. Background Technology

[0002] The operation and management of ship locks and ship lifts has always been a crucial issue in the field of water transportation, especially in hydraulic engineering facilities and large dams. The efficient and safe operation of locks and ship lifts is directly related to the smooth flow of navigation and the maintenance of the aquatic ecological environment. Traditional operation and management of locks and ship lifts rely on manual scheduling and experience. With the increase in the number of ships and the challenges of complex operating environments, traditional methods have gradually revealed problems such as inefficiency, delayed decision-making, and lack of flexibility.

[0003] In recent years, with the rapid development of automation and artificial intelligence, digital twin technology has been introduced into water conservancy and shipping systems to improve management efficiency, ensure navigation safety, and optimize operational strategies. Digital twins create virtual models of physical entities and dynamically update and interact with them using real-time data, enabling real-time monitoring, predictive analysis, and remote control of these entities. However, despite the enormous potential of digital twin technology in multiple fields, its application in the navigation management of locks and ship lifts is still in its early exploratory stages. In particular, existing technologies have not yet developed mature solutions for the deep integration and real-time display of simulation processes.

[0004] Currently, research on digital twins of locks and ship lifts mainly focuses on the modeling and data acquisition of hardware facilities, such as using big data and artificial intelligence technologies to build a safety management system for locks, or proposing digital twin methods for locks oriented towards information management. However, these studies have not explored in depth how to conduct real-time navigation simulation through digital twin systems, nor have they effectively combined simulation data with 3D model displays to provide more intuitive and refined operation management support.

[0005] There are significant gaps in the simulation and dynamic display of digital twin systems for lock and ship lift navigation. Traditional lock passage scheduling plans are ill-equipped to handle emergencies, while digital twin systems lacking simulation cannot provide forward-looking operational guidance and emergency response strategies. Furthermore, existing digital twin display technologies are often limited to static information and cannot dynamically demonstrate the specific processes of ship passage through locks, thus limiting the system's reference value and decision support role in actual operation.

[0006] There is currently no effective solution to the above problems. Summary of the Invention

[0044] Example 1

[0045] According to an embodiment of the present invention, an embodiment of a ship navigation simulation method based on a digital twin 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.

[0046] Figure 1 This is a flowchart of an optional ship navigation simulation method based on a digital twin system according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0047] Step S101: Receive simulation operation instructions, wherein the simulation operation instructions include at least ship lock passage simulation operation data, and the ship lock passage simulation operation data includes at least: simulation simulation time period, simulation speed, and scene parameters of the simulated three-dimensional space scene.

[0048] This embodiment receives simulation run instructions from the user or system through a dedicated interface. The instructions include a signal to start the simulation and a series of parameters to guide the direction, scope and details of the simulation process.

[0049] Among these, the ship lock passage simulation operation data is the core of building and running the simulation model, including the following key elements: Simulation simulation time period, which specifies the time range covered by the simulation, ranging from minutes to hours or even days. This allows users or system administrators to select a suitable time period for simulation based on immediate needs or long-term planning, thereby assessing the short-term effects or long-term trends of ship lock passage. Simulation speed is also included, determining the pace of the simulation. In practical applications, users can set the simulation speed as needed to accelerate or slow down the simulation process, thus completing simulations of longer time periods within a limited time, or slowing down the simulation when detailed analysis is required to ensure data accuracy. Additionally, scene parameters are included, defining the initial state and operating conditions of the simulated three-dimensional space scene. Scene parameters include, but are not limited to, the ship's position coordinates, the operating status and parameters of the locks, ship lifts, and auxiliary locks, such as gate opening, water level, water flow, and equipment operation time. Furthermore, dynamic information of the ship during lock passage, such as speed and direction, is also included.

[0050] Step S102: In response to the simulation operation command, retrieve the planned arrival time of ships, ship information, information on ships waiting at anchorage, the established ship passage scheduling results, the operating status of the hub equipment, and the forecast dataset from the real-time database of the lock information management system, and input them into the digital simulation model. The forecast dataset includes at least one of the following: water level forecast data, water flow forecast data, and weather forecast data. The forecast dataset is used to simulate water level changes, water flow changes, and weather changes to obtain the conditions for ship passage through the lock.

[0051] The system responds to the previously received simulation operation instructions and extracts the necessary operation data from the real-time database of the lock information management system. The data includes information on ships about to pass through the lock, details of ships currently waiting, the scheduled passage plan, equipment operating status, and forecast datasets that may affect future operations.

[0052] Specifically: The planned arrival time of vessels refers to the estimated time of arrival at the lock entrance, serving as a crucial basis for scheduling; vessel information includes basic attributes such as tonnage, type, length, and width, helping the system understand each vessel's specific needs, such as the required lock passage size and operating mode; anchorage waiting vessel information reflects the current status of vessels waiting to pass through the lock in upstream and downstream anchorages, including the number, type, and location of vessels, which is essential for predicting lock passage pressure and optimizing scheduling; the established vessel lock passage scheduling results are pre-designed lock passage sequences and schedules based on current information and rules, used to guide the simulation model's operation and evaluate the feasibility and efficiency of the plan; the operational status of the hub equipment covers the real-time operational status of the locks, ship lifts, and auxiliary locks, including equipment availability, performance indicators, and current operating modes, providing basic equipment conditions for simulation; the forecast dataset contains predicted information on external conditions such as water level, water flow, and weather. This data is used to simulate potential future environmental changes and their impact on vessel lock passage processes. By inputting the forecast dataset into the digital simulation model, the system can evaluate lock passage schemes under different conditions, providing more comprehensive risk management and decision support.

[0053] Step S103: Using a digital simulation model, the operation of the lock hub equipment is simulated based on the operating status of the hub equipment. The traffic flow of arriving ships is simulated based on the planned arrival time of ships, ship information, and information on ships waiting at anchorage. The ship passage scheduling and passage process are simulated based on the ship passage scheduling results, and the simulation results are obtained.

[0054] In this embodiment, step S103 involves inputting various information and data obtained from the real-time database into a preset digital simulation model. This model can perform multi-level simulations based on these inputs to deduce and predict the operating status of the lock hub equipment, as well as the traffic flow pattern and scheduling effect of ships passing through the lock.

[0055] Specifically, the simulation process can include simulating the operation of the lock hub equipment based on its operational status. This involves analyzing the current actual operating status of the hub equipment, including but not limited to lock gate opening and closing times, water filling and discharge times, and upstream and downstream docking and undocking times for the ship lift. This allows for a precise simulation of the lock and ship lift's operation. This simulation not only covers the normal operating status of the equipment but also considers potential malfunctions or maintenance, as well as adjustments to the operating status due to changes in natural conditions. For example, severe weather as indicated by weather forecasts may require the lock or ship lift to cease operation.

[0056] In simulating the traffic flow of arriving ships based on their planned arrival times, ship information, and information on ships waiting at anchorages, this embodiment comprehensively analyzes the planned arrival time, basic information (tonnage, type, length, width, draft, etc.), current position, and waiting status at upstream and downstream anchorages to deduce the traffic flow pattern of ships entering and passing through the lock within a specified time. This simulation considers the actual parameters of the ships, the mutual influence between ships, and the space constraints and operational capacity of the anchorages. It can predict the detailed process of ship arrival and waiting to pass through the lock, including the dwell time of ships at upstream and downstream anchorages, the timing of ships entering the waiting section, and the movement sequence and time of ships within the lock and ship lift.

[0057] Furthermore, in the process of simulating the ship lock passage scheduling and passage process based on the ship lock passage scheduling results, this embodiment further utilizes the established lock passage scheduling plan to simulate ship scheduling and lock passage operations under different operating conditions (such as normal operation, emergency evacuation, etc.). This not only verifies the rationality and efficiency of the scheduling, but also enables the scheduling plan to be optimized and adjusted based on the simulation results, ensuring the smoothness and safety of the ship lock passage process under various possible operating conditions.

[0058] Step S104: Simulate the ship's passage through the lock based on the ship's parameter information, the conditions for the ship's passage through the lock, the simulation operation data of the ship's passage through the lock, and the simulation results.

[0059] This embodiment combines the simulation results generated in the previous step with the ship's specific parameter information, lock passage conditions, and simulation operation data. By driving the changes in the three-dimensional model through a digital twin system, the entire process of the ship passing through the lock is dynamically presented.

[0060] The ship parameter information includes physical attributes such as tonnage, size, and draft, as well as real-time speed and position coordinates at different stages (e.g., entering the lock, passing through the ship lift, and navigating the channel). This embodiment binds these parameters to the ship model in the 3D model to ensure that the model's dynamic changes accurately reflect the ship's physical state. Furthermore, the lock passage conditions, combined with current water level, current speed, weather conditions, and the operating status and potential equipment malfunctions of the lock and ship lift, simulate the specific environmental conditions for ship passage through the lock and ship lift to evaluate the safety and efficiency of lock passage.

[0061] Furthermore, the ship lock passage simulation operation data includes operation instructions such as simulation time, simulation speed, and scenario parameters, as well as all ship and equipment information retrieved from the real-time database. These data together guide the operation of the simulation model.

[0062] Step S105: The simulation results of the ship passing through the lock are displayed in the digital twin system of the lock and the ship lift.

[0063] Optionally, the steps of displaying the ship lock passage simulation results in the digital twin system of the lock and ship lift include: writing the ship lock passage simulation results into the database of the digital twin system of the lock and ship lift through a data interface; driving the three-dimensional platform scene of the digital twin system of the lock and ship lift to perform simulation changes through the ship lock passage simulation results, and displaying the ship lock passage simulation results.

[0064] The data interface is a standardized interface that enables seamless integration and data exchange between different subsystems and services, ensuring that simulation results are written to the database in a unified format and protocol, including but not limited to simulation process and result data, statistical indicators, running process indicators, and display indicators.

[0065] Furthermore, the 3D platform scene in this embodiment is based on the actual layout and structure of the lock and ship lift. Through high-precision 3D modeling technology, a digital twin of the entire water conservancy project, including the lock, ship lift, waterway, and anchorage, is created. After the simulation results are written to the database, the system uses these data to drive the 3D platform scene to dynamically change, thus demonstrating the entire process of a ship passing through the lock.

[0066] Specifically, when driving the 3D platform scene to dynamically change, key elements such as the ship's position, lock gate opening, water level changes, and ship lift operation status are controlled, thus achieving a dynamic and real-time display of ship passage through the locks. This display is not limited to a static final result, but uses animation or simulation to show every stage from the ship entering the upstream and downstream anchorages until it completes the passage through the locks, including the ship's movement in the locks, ship lift, and waterway, as well as the opening, closing, and operation status of the equipment, enhancing data readability and user understanding.

[0067] Through the above steps, a simulation operation command can be received. This command includes at least ship lock passage simulation operation data, which includes at least: simulation time period, simulation speed, and scene parameters of the simulated three-dimensional spatial scenario. In response to the command, the system retrieves the planned arrival time of ships, ship information, information on ships waiting at anchorage, the established ship lock passage scheduling results, the operating status of the hub equipment, and a forecast dataset from the real-time database of the lock information management system. This data is then input into the digital simulation model. The forecast dataset includes at least one of the following: water level forecast data, water flow forecast data, and weather forecast data. This simulation is used to obtain the conditions for ship passage through the lock by simulating changes in water level, water flow, and weather. Through a digital simulation model, the operation of the lock hub equipment is simulated based on its operational status. The traffic flow of arriving ships is simulated based on planned arrival times, ship information, and information on ships waiting at anchor. The ship passage scheduling and process are simulated based on the lock passage scheduling results, yielding simulation results. The ship passage process is simulated based on ship parameter information, lock passage conditions, simulated operation data, and simulation results. The simulation results are then displayed and demonstrated in the digital twin system of the lock and ship lift. In this embodiment, a comprehensive simulation model is constructed, covering the entire process of a ship passing through the lock. It can receive real-time or forecast datasets, dynamically adjust its operating status, simulate every detail of the ship's passage through the lock, and transmit the simulation model's operating results to the digital twin platform in real time, driving the dynamic update of the 3D model. The actual position, operating status, and every detail of the equipment operation of the ship in the lock and ship lift can be reflected in the 3D scene in real time, providing a dynamic and high-fidelity display of the navigation process, ensuring the stability and safety of navigation. This solves the technical problem in related technologies where digital twin systems in lock and ship lift scenarios are limited to static information display and cannot dynamically display the specific process of a ship passing through the lock.

The main hoisting system includes the following statuses: downstream operation, main hoisting operation, downstream docking, downstream undocking, upstream vessel entering the lock chamber, upstream vessel exiting the lock chamber, downstream vessel entering the lock chamber, and downstream vessel exiting the lock chamber. The auxiliary lock includes at least one of the following: downstream gate open, downstream gate closed, vessel entering the auxiliary lock via ship lift, vessel exiting the auxiliary lock via ship lift, downstream vessel entering the lock, and downstream vessel exiting the lock chamber. The downstream gate opening angle, vessel information within the lock chamber, and the vessel's position and speed during entry and exit from the auxiliary lock are also considered. The upstream and downstream... Anchorage includes: moored vessels; intermediate channel includes: vessels underway and moored vessels; vessel includes at least one of the following: vessel's downstream status, vessel's upstream status, vessel's planar coordinates, and vessel's real-time speed, wherein the vessel's downstream status includes: waiting at the upstream anchorage, navigating from the upstream anchorage to the upstream waiting section of the lock, waiting at the upstream waiting section of the lock, entering the lock downstream, lock operation, waiting in the lock chamber downstream, navigating downstream in the intermediate channel to the mooring section, waiting at the downstream mooring section of the intermediate channel, navigating downstream in the intermediate channel to the upstream waiting section of the ship lift, and waiting at the upstream waiting section of the ship lift. The downstream status of a vessel includes: waiting at the lock, moving from the downstream anchorage to the auxiliary lock, waiting at the auxiliary lock, waiting at the auxiliary lock, and leaving the auxiliary lock.

[0072] Optionally, the digital twin system for locks and ship lifts includes: an infrastructure layer, comprising an intelligent navigation subsystem, equipment management systems, and a security management system; a data layer, which performs data processing and integration functions, including inputting lock status data, lock management data, lock service data, lock operation data, and lock support data into corresponding databases; a platform layer, comprising a video cloud platform, an IoT platform, a geographic information service platform, and an artificial intelligence platform; and an application layer, which performs ship operation monitoring, ship status monitoring, historical data review, inspection record functions, and simulation functions.

[0073] Optionally, the steps of displaying the ship lock passage simulation results in the digital twin system of the lock and ship lift include: writing the ship lock passage simulation results into the database of the digital twin system of the lock and ship lift through a data interface; driving the three-dimensional platform scene of the digital twin system of the lock and ship lift to perform simulation changes through the ship lock passage simulation results, and displaying the ship lock passage simulation results.

[0074] The following describes in detail another optional implementation method.

[0075] Figure 2 This is a schematic diagram illustrating the process of building a simulation platform for a digital twin system for navigation of locks and ship lifts according to an embodiment of the present invention. Figure 2 As shown, this study focuses on the Baise Ship Lock, ship lift, intermediate channel, upstream and downstream anchorages, and the intermediate channel anchorage as a system. A simulation model is constructed to model this system, and corresponding algorithms and modules are designed to simulate the operational process. The emphasis is on the algorithms and logic, with independent debugging and verification of the constructed model. The design of algorithms and operational processes mainly considers the following conditions: normal operation (sparse arrival of vessels, dense arrival of vessels) and emergency conditions (one-way navigation in the channel, emergency evacuation).

[0076] Based on the predicted shipping volume and a pre-set debugging dataset, the model is integrated with the integrated platform to comprehensively debug all functions of the model, including plan formulation and simulation implementation. If problems occur, the model is adjusted and modified individually, then integrated with the platform again, and this process is repeated.

[0077] The completed simulation results are written into the digital twin system database through a data interface. The data includes simulation process and result data. This data drives the three-dimensional scene of the twin platform to perform inference and change, and provides an intuitive presentation of the simulation results.

[0078] In this embodiment, the navigation facilities of the Baise Hydropower Project adopt a combination of ship lock and ship lift as an example, specifically the layout of "primary water-saving ship lock + intermediate channel + primary wire rope winch fully balanced vertical ship lift + auxiliary ship lock". The ship lock is mainly used to overcome the fluctuation of upstream water level, the ship lift is mainly used to overcome the navigation head, and the auxiliary ship lock is mainly used to overcome the fluctuation of downstream water level.

[0079] In this embodiment, the entire process of a ship passing through a lock and a ship lift is simulated, including waiting at upstream and downstream anchorages, waiting at the lock or ship lift upstream and downstream waiting sections, lock operation, ship lift operation, and navigation in the intermediate channel.

[0080] The simulation modeling process will be explained below.

[0081] A systematic analysis of the research object was conducted, and a simulation model was built to lay the foundation for the subsequent construction of a digital twin platform.

[0082] 1. Model scope and boundaries.

[0083] The model includes the locks and upstream and downstream berthing facilities, the ship lift and upstream berthing facilities, auxiliary locks, lock approach channels and intermediate channels, upstream and downstream anchorages, and intermediate channel anchorages involved in the system. The model boundaries are the upstream anchorage of the locks and the downstream anchorage of the ship lift.

[0084] 2. Operating conditions.

[0085] (1) Normal operating conditions. Evaluate the operation plan and conduct simulation and analysis of the lock operation.

[0086] (2) Lock shutdown conditions due to severe weather or lock maintenance. To determine the planned shutdown of locks or ship lifts, the waiting situation at anchorages and the evacuation of ships at anchorages can be analyzed.

[0087] (3) Operational conditions that change due to unforeseen events, such as equipment failure or landslides in the intermediate channel. This allows for analysis of the waiting situation at the anchorage and the evacuation of vessels from the anchorage.

[0088] 3. Data integration.

[0089] First, let's explain the input data. It can be divided into three categories: fixed parameters, which are parameters that remain basically unchanged as the locks, ship lifts, etc. operate; initialization parameters, which are information about the facilities, equipment, and ships in the system at the start of the simulation; and existing plans, which refer to the lock passage schedule that has been formulated at the start of the simulation, the ship arrival schedule that has been acquired, the facility and equipment maintenance schedule, and the lock shutdown schedule due to future weather changes.

[0114] (2) Vessel arrival plan: estimated arrival time of vessels that have already reported for duty, and basic information of the vessels (vessels should report for duty a certain time in advance according to management requirements);

[0124] Furthermore, let's explain the data interface design and implementation. The system establishes a standardized data exchange interface, enabling seamless connection and interaction between different systems, services, and applications. Through a unified data format, communication protocol, and access method, rapid information flow and optimized resource allocation are achieved.

[0125] Data transmission between different subsystems is achieved through data bus technology, ensuring data integrity and security. The data interface, based on relevant metadata guidelines, has been standardized and applied to the API (Application Programming Interface) model. Data exchange is based on a service model, using HTTP / HTTPS (HyperText Transfer Protocol / HyperText Transfer Protocol Secure) as the standard transmission protocol, and the message body uses the SOAP (Simple Object Access Protocol) message format. Data exchange is conducted through a message center. First, the data service needs to register with the message center. Then, during registration, relevant data interfaces are matched and invoked. Finally, the required data is retrieved through a message queue. The message center satisfies the real-time, flexible, and secure requirements of data exchange. Message subscription (requesting data) and message consumption (retrieving data) methods meet the system's own business integrity and smooth operation needs.

[0126] The following describes the operation process of the digital twin system simulation platform for navigation of the lock and ship lift.

[0127] 1. Digital twin platform base.

[0128] The Baise Smart Navigation Facilities Digital Twin System was developed using a domestically developed cloud-native digital twin platform. This platform can be flexibly expanded and customized based on application scenarios and industry needs, and possesses the capability to develop and deliver large-scale projects. It has extensive experience and mature solutions for large-scale projects in multiple industries and fields, including petrochemicals, smart cities, intelligent construction, and digital delivery.

[0129] 2. System architecture.

[0130] Figure 3 This is an architecture diagram of a digital twin system for navigation of locks and ship lifts according to an embodiment of the present invention, such as... Figure 3 As shown, the system architecture is divided into an infrastructure layer, a data layer, a platform layer, and an application layer.

[0131] Specifically, the infrastructure layer includes intelligent general aviation subsystems, equipment management systems, and security management systems.

[0132] The data layer implements data governance and business data integration functions. Data governance first involves editing model data, GIS data, and image data, then checking the topology, data accuracy, and image quality, and finally storing the data in the database. Business data integration is achieved by establishing specialized databases, including databases for lock status, lock management, lock services, lock operation, and lock maintenance.

[0133] The platform layer includes a video cloud platform, an IoT platform, a GIS platform, and an AI platform. The integrated 2D / 3D rendering engine includes GIS rendering components, environment rendering components, 3D model rendering components, effects components, data access components, layer control components, comprehensive query components, and spatial measurement components. The application building platform includes application management components, version management components, application editing components, chart management components, text management components, navigation components, custom list components, and backend management components.

[0134] The application layer includes six functional modules: comprehensive situational awareness, operation monitoring, status monitoring, historical data backtracking, inspection records, and simulation.

[0135] After an operational plan is developed using simulation software, the process and results of that plan are stored in a database. The digital twin system accesses this simulation operational plan data. Users select an operational plan within the twin system and input the time period (1-72 hours) and the simulation speed. The twin system triggers changes in the 3D scene based on the simulation data and displays the status and information of the 3D spatial scene during that time period. Status includes the ship's position, locks (gates, water levels), ship lifts (working gates, ship compartment positions, water levels), and the operational status of auxiliary lock gates. Information includes lock sequence information, ship scheduling results, ship passage times, lock operation processes and times (e.g., gate opening and closing times, water system valve opening and closing times), ship lift operation processes and times, and anchorage occupancy planning.

[0136] (1) The system retrieves data such as the planned arrival time and information of ships, information of ships waiting at anchorage, the established ship passage scheduling results, the operating status of the hub equipment, and the current status and forecast information of water level, flow rate, weather, etc. from the real-time database of the lock information management system.

[0137] (2) Based on the predicted information, the system simulates changes in water level, flow rate, weather, etc., to determine the conditions for ship passage through the lock. It also simulates equipment operation based on the operating status of the hub equipment, simulates the traffic flow of arriving ships based on the planned arrival time and ship information, and simulates the ship passage through the lock according to the selected queuing rules—that is, a simulation rehearsal. The digital twin system displays the ship model based on ship parameter information, simulating the entire process of ship passage through the lock.

[0138] (3) Supports users to select appropriate scenarios and set scenario parameters. Click the Start Simulation button to start the simulation process. The system performs simulation based on the selected scenario parameters and model algorithm.

[0139] (4) After the simulation is completed automatically, the completed simulation results are written into the database of the digital twin system through the data interface. The data includes simulation process and result data. On the one hand, the simulation result data is generated and displayed. On the other hand, the data is used to drive the three-dimensional scene of the twin platform to perform simulation changes, and the simulation results are presented intuitively.

[0140] (5) After the simulation results are generated, the user can re-define the parameters and rules as needed to perform the simulation.

[0141] According to the embodiments of the present invention, the operation plan can be dynamically formulated within 1-72 hours by simulating operation, recording data while running, based on the arrival of ships, natural conditions, equipment status, and various input operation scheduling rules.

[0142] This invention, based on simulation and analysis, simulates and analyzes the future operation of different operational plans, thereby enabling scheme comparison and providing support for targeted optimization. It rehearses the operation of locks or ship lifts over several hours, more accurately predicting equipment operating status and corresponding time points (such as the opening or closing time of gates), and the time points of each stage of ship entry and exit from the locks. This improves the experience of crew members while waiting in line and passing through the locks, and enhances lock operation management.

[0143] Based on the simulation results, the 3D model is driven by data to improve the display effect of the ship passing through the lock, thereby enhancing the display and control of the lock operation management.

[0144] The following is a detailed description with reference to another embodiment.

[0153] The aforementioned ship navigation simulation device based on a digital twin system can receive simulation operation commands through a simulation command receiving unit 41. These commands include at least ship lock passage simulation operation data, which includes at least: simulation time period, simulation speed, and scene parameters of the simulated three-dimensional spatial scenario. The data retrieval unit 42 responds to the simulation operation commands by retrieving ship arrival schedules, ship information, anchorage waiting ship information, pre-determined ship lock passage scheduling results, the operating status of key equipment, and a forecast dataset from the real-time database of the lock information management system. This data is then input into the digital simulation model. The forecast dataset includes at least one of the following: water level forecast data, water flow forecast data, and weather forecast data. The system is used to simulate changes in water level, water flow, and weather to obtain the conditions for ship passage through the lock. Through simulation unit 43, the operation of the lock hub equipment is simulated based on the operating status of the hub equipment using a digital simulation model. The traffic flow of arriving ships is simulated based on the planned arrival time of ships, ship information, and information on ships waiting at anchorages. The ship passage scheduling and passage process are simulated based on the ship passage scheduling results to obtain simulation results. Through the passage process simulation unit 44, the ship passage process is simulated based on ship parameter information, ship passage process conditions, ship passage simulation operation data, and simulation results. Through the simulation and display unit 45, the ship passage simulation results are simulated and displayed in the digital twin system of the lock and ship lift.

[0154] In this embodiment, a comprehensive simulation model is constructed, covering the entire process of a ship passing through the lock. It can receive real-time or forecast datasets, dynamically adjust its operating status, simulate every detail of the ship's passage through the lock, and transmit the simulation model's operating results to the digital twin platform in real time, driving the dynamic update of the 3D model. The actual position, operating status, and every detail of the equipment operation of the ship in the lock and ship lift can be reflected in the 3D scene in real time, providing a dynamic and high-fidelity display of the navigation process, ensuring the stability and safety of navigation. This solves the technical problem in related technologies where digital twin systems in lock and ship lift scenarios are limited to static information display and cannot dynamically display the specific process of a ship passing through the lock.
