[0022] like Figure 1 As shown, an embodiment of the present invention provides a ship operation simulation method based on geographical environment simulation, comprising: Step S101, receiving a navigation mission of a target ship, determining route information of the navigation mission, and judging whether there is a risk area in the navigation mission based on the route information.

[0023] Specifically, when conducting driving training for ship staff, targeted training is conducted according to the ship's navigation mission. The source of the ship's navigation mission usually comes from the shipowner, shipping company or port management department. The mission content may include the departure port, destination port, expected sailing time, cargo type and quantity, special requirements (such as whether it is necessary to pass through a specific checkpoint), etc. The navigation mission is recorded, including the mission number, start and end time, mission content, etc., for subsequent tracking and management. After determining the navigation mission, the route of the navigation mission is planned. The specific planning method can be to plan the best route by using tools such as electronic charts and navigation software. Among them, the considerations for planning the best route include the shortest distance, the most economical route, international waterway regulations, weather forecasts, etc. After planning the route, the planned route is recorded in detail in the navigation plan, including the starting point, end point, expected sailing time and speed of each segment. Then a risk assessment is conducted on each segment of the route. Among them, the risk assessment can be based on the expected sailing time of each segment, combined with weather forecasts, historical accident data, maritime reports and other information to assess the potential risk areas on the route. Among them, risk areas may include but are not limited to: narrow waterways, shallow waters, crowded waters, bad weather areas, pirate activity areas, etc. Among them, for risk areas, risk areas can be marked on electronic nautical charts to facilitate targeted training in subsequent steps.

[0024] Step S102, obtaining water area data and historical accident data of the risk area, constructing a regional model based on the water area data, constructing a model accident based on the historical accident data, and generating a simulation operation task according to the regional model and the model accident.

[0025] Specifically, water area data of the designated risk area is obtained, where the sources of water area data may include official nautical charts and navigation data, satellite remote sensing data, hydrological and meteorological data, port and waterway management data, etc. The types of water area data may include water area images, such as water depth, water flow, and seabed topography; meteorological data, such as wind speed, wind direction, wave height, and tide; waterway data, such as waterway width, coastline markings, etc. The acquired water area data is sorted and standardized. The data sources of historical accident data in risk areas may include maritime accident reports, insurance company data, related reports, etc. For historical accident data, the data causes of historical accident data can be further determined, such as bad weather, erroneous operation, etc.

[0026] A regional model of the risk area is constructed based on the water area data. The specific construction method can be, for example, to construct a high-precision three-dimensional model based on the water area data through three-dimensional modeling software (such as Autodesk 3ds Max, Blender, etc.), wherein the three-dimensional model is a dynamic simulation model that integrates hydrological and meteorological data to simulate the sea surface conditions under different weather conditions, such as wind, waves, tides, ocean currents, etc., and simulates the motion trajectory and dynamic behavior of ships under different conditions. Model accidents are constructed based on historical accident data, specifically including reproducing specific accident scenes based on historical accident data, including environmental conditions, ship status, operational errors, etc., where the accident occurred. Different accident classifications can be performed for different accident scenes, such as collision accidents, grounding accidents, fire accidents, mechanical failures, etc. Then, a series of simulation operation tasks are designed in combination with the regional model and the model accident, covering different accident types and environmental conditions. For the task scenarios of different simulation operation tasks, each task scenario can cover one or more risk areas, and each risk area accident scenario can also include one or more.

[0027] Step S103, collecting the operation timeline of the tester completing the simulation operation task, combining it with the preset standard operation timeline, comparing and determining the tester's erroneous operation, calculating the corresponding task score, and judging whether the task score is higher than the score threshold.

[0028] Specifically, after the tester completes the simulation operation task, the operation timeline of the tester in the simulation operation task is obtained, wherein the acquisition of the operation timeline can upload the simulation operation task to the platform for simulating navigation, and then adopt different data collection methods accordingly. For example, after the simulation operation task is uploaded to the navigation simulator, when the tester completes the simulation through the navigation simulator, a high-precision timestamp is used to record the time point of each operation node of the tester in the navigation simulator, including steering wheel rotation, throttle adjustment, brake operation, etc.; In addition, the simulation operation task can also be uploaded to the virtual reality technology receipt, and the VR technology allows the tester to immerse in the navigation simulation training. During the test, each operation of the tester in VR can also be recorded by the timestamp. For the simulation operation task, a preset standard operation timeline can be obtained, wherein the standard operation timeline can be the operation that minimizes the accident loss through computer simulation, or it can be based on the operation data of experienced crew members to establish a standard operation timeline, and the standard operation timeline includes the time point and parameter range of each key operation, as well as the allowable error range of the operation, etc.

[0029] Compare the actual operation timeline of the tester with the standard operation timeline to identify the operation nodes with large time deviations and discrepancies in operation, and compare the parameters of each operation node (such as steering wheel rotation angle, accelerator pedal position, etc.) to identify operations that exceed the allowable error range. If the tester's operation time exceeds the allowable error range of the standard operation timeline, it will be marked as an erroneous operation; if the tester's operation parameters exceed the standard parameter range, it will be marked as an erroneous operation; if the tester's operation is not within the standard operation timeline, or the part that is not operated compared with the standard operation timeline, it will be marked as an erroneous operation. According to the misoperation data, the corresponding task score is calculated. The basis for the task score can be a full score deduction system. First, the initial score (for example, 100 points) is set, and then combined with the misoperation, the score is deducted from multiple aspects such as safety, accuracy, efficiency, emergency response ability, and team writing ability. For example, safety: deduct the corresponding score according to the impact of the misoperation on safety; accuracy: deduct the corresponding score according to the degree of deviation of the operation parameters; efficiency: deduct the corresponding score according to the degree of deviation of the operation time; emergency response: adjust the score according to the tester's ability to respond in emergencies; team collaboration: if the task involves multi-person collaboration, evaluate the communication and cooperation between team members and adjust the score. Finally, determine whether the tester's task score is higher than the score threshold. When the task score is higher than the score threshold, it is considered that the tester has passed this training task and can enter the next stage of training or actual operation.

[0030] In addition, when calculating the task score, for some important navigation tasks, or when there is no authoritative standard operation timeline for the current simulation operation task, manual intervention is required to further score the simulation operation task of the navigation task. Check whether the navigation task contains manual marks. When the navigation task contains manual marks, it means that the navigation task requires manual intervention, and the tester's simulation operation task is comprehensively scored. The scoring is divided into two parts. One part is to compare and determine the tester's misoperation, and calculate the corresponding misoperation task score, that is, the original task score. The other part is the scorer, who is generally an experienced crew member, who manually scores the navigation task, and then determines the task score based on the preset scoring weight. Step S104, when the task score is lower than the score threshold, repeat the steps of: determining the model accident corresponding to the misoperation, adjusting the accident data of the model accident, generating a simulation operation task in combination with the regional model, and calculating the task score of the tester completing the simulation operation task, until the task score is higher than the score threshold, then stop the test.

[0031] Specifically, when the task score is lower than the score threshold, it means that the tester's ability is not up to standard, and the tester is required to undergo retraining and testing. Then, according to the tester's operation timeline and parameter records, the specific misoperation node is determined, and then the corresponding model accident is matched according to the type and location of the misoperation. For example, if the tester is stranded due to improper operation in a narrow channel, the corresponding stranding accident model is selected. According to the tester's misoperation, the accident data of the model accident is adjusted to make it more targeted. Among them, only the accident data of the model accident is adjusted, and the accident type is not adjusted. That is, the corresponding stranding accident corresponds to increasing the complexity or difficulty of the accident, simulating worse weather conditions, more complex channel conditions, and more complex ship conditions. For example, in a stranding accident, the wind and wave level at sea is increased, the width of the channel is reduced, and the degree of stranding of the ship is increased, but the stranding accident will not be adjusted to a collision accident, so as to train the tester for the corresponding accident more targeted. And in the adjusted simulation operation task, the key parameters in the model accident, such as wind speed, wave height, channel width, etc., are adjusted to better simulate the challenges in actual operation. Then, the operation timeline and parameter records of the tester completing the new simulation operation task are collected again, and the task score of the tester completing the simulation operation task is calculated. Until the task score is higher than the score threshold, it means that the tester has passed the targeted test of the target ship navigation task. Then the test is stopped and the result of the tester completing the test is output.

[0032] The embodiment of the present invention provides a ship operation simulation method based on geographical environment simulation, receiving the navigation task of the target ship, determining the route information of the navigation task, judging whether there is a risk area in the navigation task based on the route information; obtaining water area data and historical accident data of the risk area, constructing a regional model based on the water area data, constructing a model accident based on the historical accident data, and generating a simulation operation task according to the regional model and the model accident; collecting the operation timeline of the tester to complete the simulation operation task, combining with the preset standard operation timeline, comparing and determining the tester's misoperation, calculating the corresponding task score, and judging whether the task score is higher than the score threshold; when the task score is lower than the score threshold, repeating the steps: determining the model accident corresponding to the misoperation, adjusting the accident data of the model accident, combining with the regional model to generate the simulation operation task, calculating the task score of the tester to complete the simulation operation task, until the task score is higher than the score threshold, and stopping the test. In this way, on the one hand, the navigation skills of the crew and the emergency response capabilities to cope with various adverse situations can be efficiently improved through simulation training, and on the other hand, whether it is for novice crew members or veteran crew members, targeted navigation training can be carried out on the current navigation task, and before performing the navigation task, the current navigation task can be avoided with great probability.
