[0048] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0049] Vessels include surface vessels, warships, and underwater submarines. These vessels typically feature a dedicated control console, which integrates multiple functions for controlling the vessel, effectively improving control efficiency and safety. The control console is the core of vessel control, and its reliability is directly related to the control efficiency and safety of the vessel. High reliability ensures that the control console remains functional after repeated operations, maintaining effective control of the vessel. However, reduced reliability can cause the control console to fail, resulting in an inability to properly control the vessel, posing significant safety risks to transportation and production processes. Therefore, reliability testing of the control console is essential during the actual design process.

[0050] In the related art, reliability testing is typically conducted manually by human testers, who repeatedly test the control components in a ship's control console to obtain test results. However, during manual testing, testers cannot guarantee consistent force and speed throughout each test. The resulting test errors affect the accuracy and precision of the test results, making it impossible to effectively guide the design of ship consoles. Furthermore, manual testing is inefficient and cannot adapt to the rapid development cycle of ship consoles.

[0051] Based on the above problems, the present application discloses a reliability testing method, device, equipment and medium for a ship console, the method comprising: obtaining test tasks, including direct test tasks and indirect test tasks; controlling a test manipulator to perform direct test tasks, and obtaining direct test-related data of the ship console; obtaining resolution difficulty-related data during the execution of indirect test tasks; controlling the test manipulator according to the current status information of the ship console and the indirect test tasks, and obtaining operation intensity-related data of the test manipulator during the control process; and obtaining reliability evaluation data of the ship console based on the direct test-related data, operation intensity-related data and resolution difficulty-related data.

[0052] The reliability testing method for a ship's control console disclosed in this application evaluates the console's reliability by controlling a test manipulator to perform direct and indirect test tasks, and obtaining the manipulator's execution results and related data during the execution process. The direct test task directly tests the console's reliability, determining its performance in terms of preset operating characteristics during and after the direct test task. The indirect test task tests the console's interactive characteristics, indirectly characterizing its reliability through its ease of operation during actual operation.

[0053] Compared to related technologies, this application utilizes a test manipulator to perform reliability testing instead of human testers, improving the repeatability and stability of the reliability test, reducing test errors that occur during the test process, and increasing the precision and accuracy of the reliability test. Furthermore, this application also conducts reliability tests on ship consoles from two different perspectives, improving the accuracy and comprehensiveness of the reliability test results. This allows for the effective identification of potential issues in the ship console design and enhances the safety of the ship console during actual operation.

[0054] The reliability testing method for a vessel control console provided in this specification can be applied to the control consoles of vessels, including surface vessels, warships, and underwater submarines. It is understood that, after adaptive modification, the reliability testing method for a vessel control console provided in this specification can also be applied to other mechanical equipment to perform reliability testing on such equipment.

[0055] According to an embodiment of the present application, an embodiment of a reliability testing method for a ship control console is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0056] In this embodiment, a reliability test method for a ship console is provided, which can be used for the above-mentioned ship console. Figure 1 As shown, the method includes:

[0057] S100. Acquire a test task for testing a ship console; wherein the test task includes a direct test task for testing the reliability of the ship console and an indirect test task for testing the interactive characteristics of the ship console.

[0058] S200. Control the test manipulator to perform the direct test task, and obtain direct test related data of the ship console according to the performance of the ship console in the preset working characteristics during and after the direct test task.

[0059] S300. During the execution of the indirect test task, the display status of the ship console is analyzed to obtain data related to the difficulty of resolution; the test manipulator is controlled according to the current status information of the ship console and the indirect test task to obtain data related to the operating intensity of the test manipulator during the control process.

[0060] S400. Conduct reliability assessment on the ship console based on direct test related data, operation intensity related data, and resolution difficulty related data to obtain reliability assessment data of the ship console to guide the design of the ship console.

[0061] Among them, the direct test task can be a task of directly testing the reliability of the ship's console. The test results obtained through the direct test task include direct test related data. The direct test related data can be the average trouble-free working time, failure rate, failure density and failure mode and effect analysis results of the ship's console, which characterizes whether the ship's console can work normally during and after the direct test task.

[0062] Indirect testing tasks can indirectly test the reliability of a ship's control console, including testing its interactive features. It should be noted that the console's interactive features represent the degree to which its design provides operator convenience. High interactivity indicates high operator efficiency, reducing the likelihood of unnecessary console operations and indirectly improving the console's reliability. Low interactivity, on the other hand, indicates a high probability of repeated or incorrect operations, increasing the complexity of the operation and impacting the console's reliability. Therefore, testing the console's interactive features can indirectly reflect the console's reliability and improve the comprehensiveness and accuracy of reliability test results.

[0063] Similar to direct test-related data, the test results obtained through indirect test tasks include indirect test-related data, which can include resolution difficulty-related data and operation intensity-related data. Among them, resolution difficulty-related data is used to symbolically describe the visual confusion and visual range distribution caused by the display status of the ship console in actual navigation tasks. For example, resolution difficulty-related data is used to represent the information representation capability of the ship console. High interactivity means that the operator can quickly and accurately obtain the information represented by the ship console when operating the ship console. Operation intensity-related data is used to symbolically describe the operational complexity of the ship console in actual navigation tasks. For example, operation intensity-related data is used to represent the rationality of the component layout and ease of operation of the ship console. High interactivity can reduce unnecessary operations of the operator when operating the ship console.

[0064] A test manipulator is positioned around the ship's control console, which is within the manipulator's reach. The manipulator is used to perform controlled testing tasks and acquire test-related data. The manipulator can be a dual-arm robot, SCARA robot, DELTA robot, industrial robot, collaborative robot, or any other configuration. The number of manipulators can be two or more, depending on the specific scenario.

[0065] Specifically, after obtaining a test task for testing a ship's control console, the test manipulator is controlled to perform a direct test task, and direct test-related data is obtained during and after the direct test task based on the performance of the ship's control console in terms of preset operating characteristics. This application utilizes a test manipulator to replace the manual testing of a tester during the execution of the direct test task. Based on parameters such as the control components, operating amplitude, operating force, operating frequency, and number of operations set in the direct test task, the test manipulator is controlled to achieve high-precision and long-term repeatability testing, thereby ensuring consistency in test conditions during the reliability test and improving the accuracy of the reliability test results. In some embodiments, the control components may include components such as the ship's control console's joystick, control wheel, buttons, and switches.

[0066] Furthermore, during the indirect testing process, the display status of the ship's control console is first collected according to the indirect testing task. The display status of the ship's control console indicates the information display capability of the ship's control console, as well as the current state of the ship's control console, such as the current angle, current position, and current control state of the control components on the ship's control console. Data related to the resolution difficulty is obtained by analyzing the display status of the ship's control console, and current state information of the ship's control console is obtained based on the current state of the ship's control console indicated in the display status.

[0067] Furthermore, based on the current state of the ship's control console and parameters set in the indirect test task, such as the control components, operating amplitude, operating force, operating frequency, and number of operations, the specific task to be performed by the test manipulator is determined and the test manipulator is controlled to complete the specific task, thereby completing the indirect test task. During the control of the test manipulator, data on the load of the test manipulator during the control process is collected to obtain data related to the operating force, thereby forming a data basis for evaluating the rationality of the component layout and operational convenience of the ship's control console.

[0068] It can be understood that this application also uses a test manipulator to replace the manual testing of the tester in the process of performing indirect test tasks, controls the test manipulator according to the indirect test tasks to perform interactive characteristics testing, and obtains operation intensity related data based on the load data feedback from the manipulator, thereby enabling quantitative testing of the interactive characteristics of the ship's control console, thereby improving the accuracy and reliability of the interactive characteristics test results.

[0069] Furthermore, a comprehensive evaluation is conducted based on the obtained direct test data, operation intensity data, and resolution difficulty data to assess the reliability of the ship console, thereby obtaining ship console reliability assessment data. It is understood that the direct test data characterizes the performance of the ship console in its preset operating characteristics, directly indicating the reliability of the ship console. The operation intensity data describes the accumulated fatigue caused by the design of the ship console during actual operation of the ship, indicating the rationality of the ship console's component layout and ease of operation. The resolution difficulty data describes the operator's eye fatigue during actual operation of the ship console, indicating the ship console's information presentation capabilities. The operation intensity data and resolution difficulty data together reflect the impact of the ship console on the operator's driving behavior during actual operation. By indirectly reflecting the reliability of the ship console based on whether the operator is affected and makes unnecessary operations, the reliability of the ship console is thus improved in terms of comprehensiveness and accuracy.

[0070] This embodiment provides a reliability testing method for a ship's control console. This method controls a test manipulator to perform direct and indirect test tasks, and obtains the test manipulator's execution results and related data during the execution process, thereby evaluating the reliability of the ship's control console. The direct test task directly tests the reliability of the ship's control console, determining its performance according to preset operating characteristics during and after the direct test task. The indirect test task tests the interactive characteristics of the ship's control console, indirectly demonstrating its reliability through its ease of use during actual operation.

[0071] Compared to related technologies, this application utilizes a test manipulator to perform reliability testing instead of human testers, improving the repeatability and stability of the reliability test, reducing test errors that occur during the test process, and increasing the precision and accuracy of the reliability test. Furthermore, this application also conducts reliability tests on ship consoles from two different perspectives, improving the accuracy and comprehensiveness of the reliability test results. This allows for the effective identification of potential issues in the ship console design and enhances the safety of the ship console during actual operation.

[0072] As an embodiment of the present application, controlling the test manipulator to perform a direct test task includes:

[0073] S210. Control the test manipulator to operate the control components on the ship console according to the operating parameters corresponding to the direct test task, until the number of operations set in the direct test task is reached.

[0074] Among them, the operating parameters corresponding to the direct test task can be one or more parameters such as control components, operation amplitude, operation force, operation frequency and number of operations, so as to specify the operation of the test manipulator on the ship control console.

[0075] Specifically, during the direct test task, the control test manipulator repeatedly tests the corresponding control component according to the set operating amplitude, operating force, and operating frequency until the number of tests reaches the set number of operations. During and after the direct test task, direct test-related data related to the control component is obtained based on the performance of the control component according to the preset operating characteristics. Based on the direct test-related data of all control components on the ship console, the direct test-related data of the ship console can be obtained, thereby obtaining the test results of the direct reliability test of the ship console.

[0076] As an embodiment of the present application, before controlling the test manipulator to perform a direct test task, the process includes:

[0077] S202. Perform spatial path planning on the test manipulator according to the control components and operation amplitude corresponding to the direct test task to obtain a direct test path of the test manipulator for controlling the test manipulator to perform the direct test task.

[0078] Reference Figure 2a As shown, points A1, B1, and C1, as well as points A2, B2, and C2, are located at different locations on the same control component. Points A1, B1, and C1 correspond to the control component status displayed in the current status information of the ship's control console. Points A2, B2, and C2 correspond to the control component status after operation according to the operating parameters set for the direct test task. Points A1 and A2 correspond to each other, points B1 and B2 correspond to each other, and points C1 and C2 correspond to each other. It can be understood that during the test process, a circular arc spatial path exists between points A1 and A2. Similarly, a circular arc spatial path exists between points B1 and B2, and between points C1 and C2. These spatial paths can all serve as direct test paths for testing the manipulator.

[0079] It should be noted that when the test manipulator is controlling the control component, the spatial path it traverses will vary depending on the contact point between the test manipulator and the control component. Therefore, it is necessary to plan the test manipulator's spatial path based on the spatial characteristics of each path, such as whether the path passes through other control components and the length of the path. Direct test paths corresponding to direct test tasks are typically shorter and only pass through a single control component.

[0080] Reference Figure 2bAs shown, points A, B and C are points at different positions on the same control component. Since the mechanical strength and electrical component design of different positions of the control component are different, the direction in which the test manipulator applies force to the control component is different according to the different contact positions between the test manipulator and the control component, and the direct test related data obtained thereby are different, which in turn leads to errors in the reliability test results. In some embodiments, when performing spatial path planning for the test manipulator, the control component can be subjected to a strength analysis based on conditions such as the shape, external dimensions and electrical component design of the control component, thereby determining the weaker structure in the control component and obtaining an operating method that can reflect the reliability of the structure, so as to control the test manipulator, obtain corresponding direct test related data, and improve the accuracy of the reliability test results.

[0081] Reference Figure 3 As shown, as an embodiment of the present application, the direct test related data includes electrical reliability related data and mechanical reliability related data; during and after the direct test task, based on the performance of the ship console in preset working characteristics, the direct test related data of the ship console is obtained, including:

[0082] S220. Obtain electrical reliability related data of the ship console based on the electronic signals output by the ship console during and after the direct test mission.

[0083] S230. Detect the reaction impedance of the control components on the ship console, and obtain mechanical reliability related data of the ship console based on the reaction impedance.

[0084] S240. Obtain direct test related data of the ship control console based on the electrical reliability related data and the mechanical reliability related data.

[0085] Among them, the electrical reliability related data may include whether the control components on the ship's console can send out electronic signals and whether they can send out electronic signals correctly, etc. The mechanical reliability related data may include whether the control components on the ship's console are damaged, and one or more of the stiffness data and reaction impedance of the control components when being operated.

[0086] Specifically, during and after the direct testing mission, the ship's control console is inspected to obtain direct test data. By operating any control component, the correct functioning of its electrical components is determined based on the electronic signals output by that control component, thereby obtaining data related to the electrical reliability of that control component. Based on the electrical reliability data of all control components, the ship's control console's electrical reliability data can be obtained.

[0087] Furthermore, by operating any control component, the mechanical reliability related data of the control component can be obtained based on the reaction impedance and other data fed back by the control component during the inspection process. The mechanical reliability related data of the ship control console can be obtained based on the mechanical reliability related data of all control components.

[0088] Furthermore, based on the electrical reliability related data and the mechanical reliability related data of the ship console, it can be determined whether the ship console can work normally after a direct test task, thereby enabling a direct evaluation of the reliability of the ship console.

[0089] Reference Figure 4 As shown, as an embodiment of the present application, controlling the test manipulator according to the current state information of the ship console and the indirect test task includes:

[0090] S410. Decompose the indirect test task into any number of subtasks according to the current state information, and perform task planning on the any number of subtasks to obtain a subtask sequence.

[0091] S420. Control the test manipulator to test the ship control console according to the subtask sequence to complete the indirect test task.

[0092] Specifically, the current state information represents the control status of the control components on the ship's control console. By comparing this current state information with the indirect test task, the control components that need to be operated during the indirect test task and the corresponding operation ranges of each control component are determined. Subtasks are then organized based on the obtained control components and corresponding operation ranges. These subtasks are then planned based on information such as the operation sequence of the control components in the indirect test task to generate a subtask sequence, which is used to control the test manipulator to complete the indirect test task.

[0093] As an embodiment of the present application, after decomposing the indirect test task into any number of subtasks according to the current state information and performing task planning on the any number of subtasks to obtain a subtask sequence, the following steps are included:

[0094] S412. Perform spatial path planning for the test manipulator according to the control components corresponding to the subtask sequence on the ship console to obtain an indirect test path for the test manipulator, which is used to control the test manipulator to perform the indirect test task.

[0095] Specifically, the subtasks include the control components that need to be operated during the indirect test task, as well as the corresponding operating ranges for each control component. Based on the position and dimensions of the control components before and after the operation, the spatial path traversed by the test manipulator during the operation is determined, resulting in an indirect test path, which is then used to control the test manipulator. Compared to direct test paths, indirect test paths corresponding to indirect test tasks are typically longer and pass through multiple control components.

[0096] Reference Figure 5 As shown, as an embodiment of the present application, the reliability evaluation data is obtained by the following method:

[0097] S510. Compare the electrical reliability related data with the electrical reliability threshold to obtain the electrical reliability test result.

[0098] S520. Compare the mechanical reliability related data with the mechanical reliability threshold to obtain the mechanical reliability test result.

[0099] S530. Compare the resolution difficulty related data with the resolution difficulty threshold to obtain the resolution difficulty test result.

[0100] S540. Compare the operation intensity related data with the operation intensity threshold to obtain the operation intensity test result.

[0101] S550. Perform weighted calculation on the electrical reliability test results, mechanical reliability test results, resolution difficulty test results, and operation strength test results to obtain reliability evaluation data.

[0102] Among them, the data related to resolution difficulty include the brightness data, color data and resolution accuracy data of the display screen of the ship's control console; the data related to operation intensity include the torque data, operation frequency and operation time of the test manipulator during the control process.

[0103] Specifically, electrical reliability thresholds can include electrical signal amplitude and frequency, used to determine whether the control component is properly outputting electrical signals. Mechanical reliability thresholds can include reaction impedance thresholds and stiffness thresholds, used to determine whether the control component is functioning properly. The electrical and mechanical reliability test results can be used to assess the performance of the vessel control console in direct testing tasks.

[0104] Furthermore, a difficulty threshold is set for the difficulty-of-recognition data. For example, the difficulty threshold can be based on the minimum discernible brightness, color difference threshold, and resolution accuracy threshold when observing the ship's control console by the human eye. If the display screen does not meet any of the difficulty thresholds, the tester may not be able to accurately identify the control information displayed on the screen, which may result in the operator being unable to correctly operate the ship's control console, indirectly affecting the reliability of the ship's control console.

[0105] Furthermore, operational intensity thresholds are set for operational intensity data. For example, these thresholds may include the operator's maximum grip torque, maximum pressing force, operation frequency threshold, and operation time threshold when operating the ship's control console. The maximum grip torque and maximum pressing force reflect the operator's operational requirements, while the operation frequency threshold and operation time threshold reflect the fatigue caused by the ship's control console. Improper design increases the risk of operator errors, indirectly impacting the reliability of the ship's control console.

[0106] Furthermore, the test results can be evaluation data related to relevant data. According to the weights corresponding to each test result, the electrical reliability test results, mechanical reliability test results, resolution difficulty test results and operation strength test results are weightedly calculated to obtain the reliability evaluation data of the ship console.

[0107] Accordingly, please refer to Figure 6 The embodiment of the present application provides a reliability testing device for a ship control console, the device comprising:
