[0020] like Figure 6 As shown, step S5 specifically includes Step S51) Improve the loading / reloading process, formulate detailed operation standards and processes, and perform multiple tasks in parallel; Step S52) Rationally allocate personnel according to workload and complexity; Step S53) Optimize material storage and management, and prepare all tools and materials required for replacement in advance.

[0021] Example 1 discloses a simulation method for rapid installation / replacement of ship equipment based on process node drive, such as Figure 7 As shown, the following steps are included: 1) Simulation starts, start the simulation software, enter the main interface, and choose to load an existing simulation project; 2) Select the equipment to be added or replaced. Select the equipment to be added or replaced from the predefined equipment library. The system supports the selection of multiple equipment types, such as pianos, radars, generator sets, flow meters, propeller integrated devices, air compressors, deep-sea winches, and valve pumps.

[0022] 3) Data input: The following data must be entered: Equipment specifications (including model, size, weight, power), operating conditions (factors affecting operation, such as temperature, humidity, sea conditions), environmental factors (including surrounding workspace conditions, location of other equipment).

[0023] 4) Configure simulation parameters and set the following simulation parameters to affect the simulation results: Time parameters (setting simulation duration and time step), physical parameters (such as gravity, fluid dynamics), and result output method (select the format of the output report, such as graphics, text, or data table).

[0024] Run the simulation. The system performs simulation based on the input data and configured parameters, simulates the equipment installation and replacement process, and performs real-time monitoring; Create a simulation environment, including: Equipment model creation (generating corresponding 3D models based on input equipment specifications), simulation environment construction (building suitable simulation scenarios, including marine environment and weather conditions), and visualization interface setting (users can customize the visualization interface to optimize information display).

[0025] 7) Determine the execution nodes. During the simulation process, the system automatically identifies key execution nodes, such as equipment disassembly, equipment transportation, and equipment installation, and records the status and time of each node.

[0026] 8) Result analysis. After the simulation is completed, the system analyzes the results and generates comparative data, including time cost, resource utilization, and safety hazards.

[0027] 9) Clothing change decision: Based on the result analysis, make clothing change decision suggestions to help users evaluate whether to actually change clothes.

[0028] 10) Perform the refit. If the decision is passed, perform the actual operation according to the system's suggestions and optimize the refit process with reference to the simulation results; If the decision is not passed, restart the simulation.

[0029] 11) After the simulation is completed and all steps are completed, the system saves the simulation data and generates a complete simulation report, which can be viewed and printed at any time.

[0030] The behavior node template of this embodiment is as follows Figure 8 As shown, it includes root nodes, sequence nodes, selection nodes, parallel nodes, conditional nodes and action nodes.

[0031] In a sequential node, each step is performed in order, and if a step fails to complete, it will be terminated early; Under the selection node, you can complete it as long as one of the following steps is met; In parallel nodes, child nodes will run simultaneously, requiring all child nodes to complete successfully; Under the conditional node, this condition must be met for success; An action node is an execution node, which is an execution action.

[0032] In this template, the root node is a sequential node. The equipment is added or replaced in a main line sequence. The root node contains sequential nodes, parallel nodes, and selection nodes. There are selection nodes under the sequential node. A certain condition must be met before the next action can be performed. For example, it is necessary to determine whether the screws have been unscrewed before the next step of equipment disassembly can be performed. The condition nodes and action nodes under the sequential node correspond to the conditions that need to be achieved and the specific execution actions, respectively.

[0033] Under the parallel node, there are multiple sequential nodes. Under the condition that multiple sequential nodes do not affect each other, we can execute them in parallel to improve efficiency. Each sequential node may be completed at different times, but the parallel operation is considered successful only after all of them are completed.

[0034] There can be multiple action nodes and sequence nodes under the selection node. As long as any one of the following is completed, the selection node can be completed. For example, in some emergencies, one of them may occur, and you only need to solve the one that occurs.

[0035] like Fig. 9 As shown, based on Figure 2 The node-driven valve pump replacement method, the execution nodes of which include: Open the small guide door, fix the water pump with a hand chain hoist, remove the water pump junction box, remove the water pump raft isolator bolts, remove the floor around the water pump, remove the inlet and outlet water pipes, remove the control valve, move the water pump to the hatch, move the crane to the target position, block the inlet and outlet water pipes, drill holes to remove burrs, check with a feeler gauge, hang a new water pump, torque the water pump raft isolator bolts, remove the blind head, install the control valve, install the inlet and outlet water pipes, install the floor around the water pump, and install the water pump junction box; The entire simulation process is carried out sequentially according to the node behavior tree.

[0036] like Fig.10 As shown, in the ship equipment replacement simulation system, the entire process runs smoothly according to the logic of this behavior tree.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
