Description

Technical Field

[0001] The invention belongs to the technical field of troubleshooting and maintenance in a virtual environment of ship electromechanical equipment, and relates to a troubleshooting and maintenance system in a virtual environment of ship electromechanical equipment. Background Art

[0002] With the continuous development of ship technology, the automation and intelligence of electromechanical equipment are becoming higher and higher, and its internal structure and working principle are becoming more and more complex, which makes it more difficult for maintenance personnel to accurately master relevant knowledge and skills, and puts higher requirements on the comprehensive quality of maintenance personnel. In traditional ship electromechanical equipment maintenance training, it mainly relies on theoretical teaching combined with actual equipment operation. Theoretical teaching is often more abstract, and it is difficult for maintenance personnel to closely link the knowledge in books with the complex structure and operation of actual equipment. Although the actual equipment operation is intuitive, it is subject to many restrictions. For example, the price of ship electromechanical equipment is expensive, and it is impossible for maintenance personnel to simulate faults and practice repeatedly at will. Therefore, the troubleshooting and maintenance system based on the virtual environment of ship electromechanical equipment is of great significance and role.

[0003] In the prior art, there are also some related solutions for troubleshooting and maintenance in a virtual environment for ship electromechanical equipment. For example, a maintenance data import method and system for ship electromechanical equipment fault information simulation is disclosed in China Patent Publication No. CN115938188A, which includes: three-dimensional modeling of equipment model, external environment, and detection tool in a ship electromechanical equipment fault information simulation system according to equipment photos and drawings; judging whether the three-dimensional model obtained by the three-dimensional modeling of the equipment model, external environment, and detection tool is qualified, and if qualified, importing the three-dimensional model into the ship electromechanical equipment fault information simulation system; importing the maintenance data corresponding to the fault information into the ship electromechanical equipment fault information simulation system according to the collected fault information to simulate the maintenance action in the ship electromechanical equipment fault information simulation system, etc. Its benefit lies in providing a maintenance data import method and system for ship electromechanical equipment fault information simulation that can simulate the real maintenance process.

[0004] There is also a Chinese patent publication number CN115810300A, which is a method for demonstrating a fault maintenance solution in a virtual environment of ship electromechanical equipment, including: constructing a virtual environment of ship electromechanical equipment and its physical elements and fault database on a server; the server responds to a demonstration request from a training terminal, queries the fault content data and corresponding maintenance demonstration data in the fault database corresponding to the demonstration request; feeds back the fault content data and maintenance demonstration data to the training terminal, and displays the virtual environment of ship electromechanical equipment on the training terminal; the training terminal gradually delays the fault maintenance solution in the virtual environment of ship electromechanical equipment according to the changes of physical elements in the training terminal according to the user's operation of the training terminal and the fault content data and maintenance demonstration data. Its benefit lies in providing a method for realistically demonstrating fault maintenance by dynamically reproducing the ship electromechanical equipment represented by the physical elements in a virtual environment.

[0005] Although the above schemes have proposed some solutions for troubleshooting and maintenance of ship electromechanical equipment in a virtual environment, there are still certain limitations: the existing schemes mainly provide a maintenance data import method for simulating the fault information of ship electromechanical equipment that simulates the real maintenance process, or a method for realistically demonstrating fault maintenance by dynamically reproducing the ship electromechanical equipment represented by the physical elements in a virtual environment. However, the existing schemes ignore the detection and analysis of the simulated operations of maintenance personnel in troubleshooting and maintenance in a virtual environment, so that maintenance personnel cannot discover and correct their own strengths and weaknesses in the maintenance process, nor can they formulate personal development plans for maintenance personnel, which is not conducive to promoting the personal development of maintenance personnel, improving the overall level of the maintenance team, ensuring the stable operation of equipment, and promoting technological innovation and progress.

The target ship virtual environment and the simulated state of the fault of each type of electromechanical equipment of each ship therein are further collectively referred to as the target ship electromechanical equipment virtual environment.

[0009] The virtual environment verification module is used to obtain the comparative information of the virtual environment of the target ship's electromechanical equipment and analyze the evaluation of the virtual environment of the target ship's electromechanical equipment. If it is qualified, the troubleshooting and maintenance startup module is executed; if it is unqualified, the virtual environment construction module is executed.

[0010] The troubleshooting and maintenance startup module is used by maintenance personnel to start the virtual environment of the target ship's electromechanical equipment according to predefined principles to perform troubleshooting and maintenance simulation operations and learning.

[0011] The troubleshooting and maintenance analysis module is used to obtain the process information of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, analyze the evaluation indicators of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, and provide feedback.

[0013] The evaluation feedback module is used to analyze the comprehensive evaluation of each maintenance personnel's troubleshooting maintenance test.

[0014] The information base is used to store the process information and evaluation indicators of each troubleshooting and maintenance test of each maintenance personnel, and store the standard process information of each troubleshooting and maintenance test corresponding to each fault simulation state of the maintenance personnel.

[0037] It should be noted that the construction flow chart of the fault simulation state of each type of electromechanical equipment of each ship in the target ship virtual environment is as follows: Figure 3 shown.

[0038] The virtual environment verification module is used to obtain the comparative information of the virtual environment of the target ship's electromechanical equipment and analyze the evaluation of the virtual environment of the target ship's electromechanical equipment. If it is qualified, the troubleshooting and maintenance startup module is executed; if it is unqualified, the virtual environment construction module is executed.

[0039] As a preferred feasibility example, the comparison information of the virtual environment of the electromechanical equipment of the target ship includes the ship similarity and the fault similarity of the electromechanical equipment of each type of ship.

[0040] It should be further explained that the reasons for using the ship similarity and the similarity of the electromechanical equipment failures of each type of ship as the comparison information of the target ship electromechanical equipment virtual environment are: (1) By analyzing the ship similarity, it is helpful to analyze the realism of the ship in the virtual environment of the target ship electromechanical equipment in terms of appearance structure and operation, which is conducive to further targeted optimization and improvement. (2) By analyzing the similarity of the electromechanical equipment failures of each type of ship, it is helpful to analyze the similarity of the electromechanical equipment failures of each type of ship in the virtual environment of the target ship electromechanical equipment with the actual failures in terms of phenomena and the degree of impact on related equipment, which is conducive to further targeted optimization and improvement.

[0041] It should be further explained that the specific method for obtaining the ship similarity of the target ship electromechanical equipment virtual environment is: the three-dimensional modeling of the ship in the target ship electromechanical equipment virtual environment is compared with the standard three-dimensional model of the target ship stored in the information library to obtain the degree of overlap between the three-dimensional modeling of the ship in the target ship electromechanical equipment virtual environment and the standard three-dimensional model of the target ship, which is recorded as the appearance and structure similarity of the target ship electromechanical equipment virtual environment. .

[0042] The operation record data of each electromechanical equipment in the virtual environment of the target ship's electromechanical equipment are obtained through virtual sensors, and then the operation record data of each electromechanical equipment in the virtual environment of the target ship's electromechanical equipment are evaluated by professionals to obtain the operation similarity score of each electromechanical equipment in the virtual environment of the target ship's electromechanical equipment. ,in , is the number of each electromechanical equipment, is the number of electromechanical equipment, and the similarity of the target ship's electromechanical equipment virtual environment to the ship's operation is analyzed ,in The minimum operation similarity score of the electromechanical equipment in the virtual environment of the target ship's electromechanical equipment is set.

[0043] According to the analytical formula Get the ship similarity of the target ship's electromechanical equipment virtual environment .

[0044] The specific method for obtaining the similarity of each type of ship electromechanical equipment failure in the virtual environment of the target ship electromechanical equipment is as follows: the phenomenon record data of each type of ship electromechanical equipment failure in the virtual environment of the target ship electromechanical equipment is obtained by using a virtual sensor, and then the phenomenon record data of each type of ship electromechanical equipment failure in the virtual environment of the target ship electromechanical equipment is evaluated by professionals to obtain the phenomenon similarity score of each type of ship electromechanical equipment failure in the virtual environment of the target ship electromechanical equipment. ,in , For each type of number, is the number of types, , is the number of each ship's mechanical and electrical equipment failure, is the number of ship electromechanical equipment failures, and analyzes the similarity of the corresponding failure phenomena of each type of ship electromechanical equipment in the virtual environment of the target ship electromechanical equipment ,in It is the minimum phenomenon similarity score of the ship electromechanical equipment failure of the type in the virtual environment of the target ship electromechanical equipment. Similarly, the similarity score of the recorded data of the impact of each type of ship electromechanical equipment failure on the associated equipment in the virtual environment of the target ship electromechanical equipment can be obtained. , analyze the impact similarity of each type of ship electromechanical equipment corresponding to the associated equipment in the virtual environment of the target ship electromechanical equipment .

[0045] According to the analytical formula Obtain the fault similarity of each type of ship electromechanical equipment in the virtual environment of the target ship electromechanical equipment .

[0046] As a preferred feasibility example, the specific analysis method of the evaluation of the virtual environment of the target ship electromechanical equipment is as follows: extract the ship similarity of the virtual environment of the target ship electromechanical equipment and the fault similarity of each type of ship electromechanical equipment, which are recorded as ,in , For each type of number, is the number of types, , is the number of each ship's mechanical and electrical equipment failure, The number of ship electromechanical equipment failures is used to analyze the evaluation index of the target ship electromechanical equipment virtual environment. ,in They are the weight factors of the evaluation indicators corresponding to the set ship similarity and ship electromechanical equipment failure similarity.

[0047] A specific example, .

[0048] Ship similarity is usually compared based on multiple features of the ship, such as appearance, structure, and operation. Although these features are important for identifying the similarities and differences of ships, they do not dominate the troubleshooting and maintenance simulation of ship electromechanical equipment. Therefore, the weight factor of the evaluation index corresponding to the ship similarity is recorded as 0.25.

[0049] The similarity of each type of ship electromechanical equipment failure is usually compared based on the similarity of the phenomenon of the ship electromechanical equipment failure and the degree of impact on related equipment with the actual failure. It plays a dominant role in the troubleshooting and maintenance simulation of ship electromechanical equipment. Therefore, the weight factor of the evaluation index corresponding to the similarity of ship electromechanical equipment failure is assigned to 0.75.

[0050] The evaluation index of the virtual environment of the target ship's electromechanical equipment is compared with the set evaluation index threshold. If the evaluation index of the virtual environment of the target ship's electromechanical equipment is greater than the evaluation index threshold, the evaluation of the virtual environment of the target ship's electromechanical equipment is recorded as qualified; otherwise, the evaluation of the virtual environment of the target ship's electromechanical equipment is recorded as unqualified.

[0051] The present invention helps to construct a more realistic virtual environment for target ship electromechanical equipment by constructing a virtual environment for target ship electromechanical equipment and analyzing its evaluation situation, thereby helping maintenance personnel to better understand the causes and mechanisms of faults and conduct troubleshooting and maintenance drills therein, helping to reduce the trial and error costs in actual maintenance and improving the maintenance personnel's practical ability and emergency handling ability in troubleshooting and maintenance.

[0052] The troubleshooting and maintenance startup module is used by maintenance personnel to start the virtual environment of the target ship's electromechanical equipment according to predefined principles to perform troubleshooting and maintenance simulation operations and learning.

[0053] As a preferred feasibility example, the content of starting the virtual environment of the target ship's electromechanical equipment according to predefined principles is: each maintenance personnel selects troubleshooting and maintenance tests according to his or her own troubleshooting and maintenance level, and then starts and confirms operations in the virtual environment of the target ship's electromechanical equipment.

[0054] It should be noted that when each maintenance personnel selects a troubleshooting maintenance test according to their own troubleshooting maintenance level, they can repeatedly select completed troubleshooting maintenance tests, or select a new troubleshooting maintenance test according to the current troubleshooting maintenance test progress.

[0055] The troubleshooting and maintenance analysis module is used to obtain the process information of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, analyze the evaluation indicators of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, and provide feedback.

[0056] As a preferred feasibility example, the process information of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state includes fault troubleshooting sequence compliance, fault troubleshooting conclusion accuracy, maintenance operation sequence compliance, maintenance operation standardization and maintenance operation accuracy.

[0057] It is necessary to further explain that the reasons for using the fault troubleshooting sequence compliance, fault troubleshooting conclusion accuracy, maintenance operation sequence compliance, maintenance operation standardization and maintenance operation accuracy as the process information of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state are: (1) It helps maintenance personnel to conduct fault troubleshooting training in a scientific and reasonable sequence, laying the foundation for subsequent maintenance work. (2) It helps to train maintenance personnel to obtain accurate fault troubleshooting conclusions, which is conducive to subsequent maintenance personnel to perform targeted maintenance operations. (3) It helps to train maintenance personnel to perform maintenance operations according to a certain sequence and process, which is conducive to ensuring the quality of subsequent maintenance and equipment safety, avoiding operational errors and safety hazards. (4) The standardization of maintenance operations is one of the important indicators for measuring the professional level of maintenance personnel. It helps to train maintenance personnel to standardize maintenance operations, which is conducive to reducing the risks of equipment damage, personal injury and other risks in the future and improving maintenance quality. (5) It helps to train maintenance personnel to be accurate in maintenance operations, which is conducive to ensuring that subsequent equipment failures are completely repaired and avoiding failure recurrence.

[0058] It needs to be further explained that the specific method for obtaining the conformity of the fault troubleshooting sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state is as follows: in the virtual environment of the target ship's electromechanical equipment, the whole process of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state is recorded by the log recording function, and it is recorded as the whole process record of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state, and then the fault troubleshooting sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state is extracted therefrom, and it is compared with the standard troubleshooting sequence of the maintenance personnel's current troubleshooting maintenance test to each fault simulation state stored in the information database, and the number of steps that are consistent with the standard troubleshooting sequence of the maintenance personnel's current troubleshooting maintenance test to each fault simulation state is obtained, and it is ratioed with the total number of steps of the standard troubleshooting sequence of the maintenance personnel's current troubleshooting maintenance test to each fault simulation state, and the quotient is recorded as the conformity of the fault troubleshooting sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state.

[0059] The specific method for obtaining the accuracy of the troubleshooting conclusions of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state is as follows: extract the troubleshooting conclusions of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state from the full process record of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, and compare the standard troubleshooting conclusions of the maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state stored in the information database; if the troubleshooting conclusion of a maintenance personnel's current troubleshooting maintenance test corresponding to a fault simulation state is consistent with its standard troubleshooting conclusion, then the accuracy of the troubleshooting conclusion of the maintenance personnel's current troubleshooting maintenance test corresponding to the fault simulation state is recorded as 1; otherwise, the accuracy of the troubleshooting conclusion of the maintenance personnel's current troubleshooting maintenance test corresponding to the fault simulation state is recorded as 0.

[0060] In a specific example, the current troubleshooting maintenance test of a maintenance personnel corresponds to a fault simulation state which is an engine electrical short circuit fault simulation state, and the standard troubleshooting conclusion of the current troubleshooting maintenance test of the maintenance personnel corresponding to the fault simulation state is an engine electrical short circuit fault simulation state.

[0061] The specific method for obtaining the degree of conformity of the maintenance operation sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state is as follows: the method for obtaining the degree of conformity of the fault troubleshooting sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state can be used to obtain the degree of conformity of the maintenance operation sequence of each maintenance personnel's current troubleshooting maintenance test to each fault simulation state.

[0062] The specific method for obtaining the degree of standardization of maintenance operation of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state is as follows: extracting the maintenance operation video of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state from the whole process record of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, comparing it with the standard maintenance operation video of the maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state stored in the information database, obtaining the number of operation steps of the maintenance operation video of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state that is consistent with its standard maintenance operation video, and comparing it with the total number of operation steps of the standard maintenance operation video of the maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, and the obtained quotient is recorded as the degree of standardization of maintenance operation of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state.

[0063] The specific method for obtaining the maintenance operation accuracy of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state is as follows: extracting the results of each maintenance operation of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state from the whole process record of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, and comparing it with the standard results of each maintenance operation of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state stored in the information database, and obtaining the number of times that the results of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state are consistent with the standard results after the maintenance operation, and ratioing it with the total number of maintenance operations of the maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, and the obtained quotient is recorded as the maintenance operation accuracy of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state.

[0064] A specific example is that the current troubleshooting maintenance test of a maintenance personnel corresponds to a fault simulation state which is an engine electrical short circuit fault simulation state. Then the standard result after the last maintenance operation of the current troubleshooting maintenance test of the maintenance personnel corresponding to the engine electrical short circuit fault simulation state is that the insulation resistance of the engine-related circuits is greater than the set insulation resistance threshold.

[0065] As a preferred feasibility example, the specific analysis method of the evaluation index of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state is: extract the fault troubleshooting sequence compliance, fault troubleshooting conclusion accuracy, maintenance operation sequence compliance, maintenance operation standardization and maintenance operation accuracy of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state, and record them as ,in , is the maintenance personnel's number, is the number of maintenance personnel, , is the number of each fault simulation state, is the number of fault simulation states, and analyzes the evaluation indicators of each maintenance personnel's current troubleshooting maintenance test corresponding to each fault simulation state ,in They are respectively the preset fault troubleshooting sequence compliance threshold, maintenance operation sequence compliance threshold, maintenance operation standardization threshold and maintenance operation accuracy threshold corresponding to the fault simulation state of the current fault troubleshooting maintenance test of the maintenance personnel.

[0066] The present invention obtains process information of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, and analyzes the evaluation index of each maintenance personnel's current troubleshooting and maintenance test corresponding to each fault simulation state, which helps maintenance personnel to discover and correct their own strengths and weaknesses in the maintenance process, and make targeted improvements to enhance their troubleshooting and maintenance capabilities, thereby ensuring that subsequent maintenance work complies with specifications and requirements, and also helps to reasonably arrange maintenance resources and spare parts to avoid unnecessary waste.
