[0002] Vessels usually have dedicated vessel consoles, which integrate various functions for controlling vessels, effectively improving the control effect and safety of vessels. The vessel console is the core for controlling vessels, and the reliability of the vessel console is directly related to the control effect and safety of the vessels. Higher reliability can ensure that the vessel console can still work normally after multiple operations and maintain effective control of the vessels.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] Vessels may include surface vessels, warships and submarines navigating underwater. These vessels are usually equipped with dedicated vessel consoles, which integrate various functions for controlling the vessels, effectively improving the control effect and safety of the vessels. The vessel console is the core for controlling the vessel, and the reliability of the vessel console is directly related to the control effect and safety of the vessel. Higher reliability can ensure that the vessel console can still work normally after multiple operations and maintain effective control of the vessel. However, a decrease in reliability will cause the vessel console to fail, resulting in the inability to control the vessel normally, bringing great safety risks to the transportation process and production process. Therefore, it is essential to conduct reliability tests on the vessel console during the actual design process of the vessel console.

[0021] In the related art, common reliability tests are mainly carried out manually by testers. The testers repeatedly test the control components in the vessel console to obtain test results. During the manual testing process, the testers cannot ensure that the force and speed are unified in each test. The resulting test errors will affect the accuracy and precision of the test results, leading to the inability to effectively guide the design of the vessel console. In addition, the efficiency of manual testing is low and cannot adapt to the rapid development cycle of the vessel console.

[0022] Based on the above problems, the present application discloses a reliability testing method, device, equipment and medium for a vessel console. The method includes: obtaining test tasks, including direct test tasks and indirect test tasks; controlling a test manipulator to execute the direct test tasks to obtain direct test-related data of the vessel console; during the execution of the indirect test tasks, obtaining data related to the discrimination difficulty; controlling the test manipulator according to the current state information of the vessel console and the indirect test tasks to obtain operation intensity-related data during the control process of the test manipulator; and obtaining reliability evaluation data of the vessel console based on the direct test-related data, operation intensity-related data and discrimination difficulty-related data.

[0023] The reliability testing method for the vessel console disclosed in the present application controls a test manipulator to execute direct test tasks and indirect test tasks, and obtains the execution results of the test manipulator and related data during the execution process, so as to evaluate the reliability of the vessel console. Among them, the direct test tasks are used to directly test the reliability of the vessel console and determine the performance of the vessel console in preset working characteristics during and after the direct test tasks; the indirect test tasks are used to test the interaction characteristics of the vessel console, and indirectly characterize the reliability of the vessel console by the operation convenience of the vessel console in the actual operation process.

[0024] Compared with the related technology, the present application uses a test manipulator to replace a test person for reliability testing, improves the repeatability and stability of the reliability testing, reduces the test errors occurring during the testing process, and improves the test accuracy and accuracy of the reliability testing. In addition, the present application also conducts reliability testing on the vessel console from two different perspectives, improves the accuracy and comprehensiveness of the reliability testing results, and thus can effectively discover potential problems existing in the design of the vessel console, and improves the safety of the vessel console in the actual operation process.

[0025] The reliability testing method for the vessel console provided in this specification can be applied to the vessel console of a vessel. The vessel can include surface vessels, warships and submarines navigating underwater. It can be understood that after adaptive modification, the reliability testing method for the vessel console provided in this specification can also be applied to other mechanical equipment to conduct reliability testing on these mechanical equipment.

[0026] According to an embodiment of the present application, an embodiment of a reliability testing method for a vessel 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0027] In this embodiment, a reliability test method for a vessel console is provided, which can be used for the above-mentioned vessel console. Refer to Figure 1 As shown, the method includes: S100. Obtain a test task for testing the vessel console; wherein, the test task includes a direct test task for testing the reliability of the vessel console and an indirect test task for testing the interaction characteristics of the vessel console.

[0028] S200. Control the test manipulator to execute the direct test task, and obtain the direct test-related data of the vessel console according to the performance of the vessel console on the preset working characteristics during and after the direct test task.

[0029] S300. During the execution of the indirect test task, analyze the display state of the vessel console to obtain the data related to the discrimination difficulty; control the test manipulator according to the current state information of the vessel console and the indirect test task to obtain the data related to the operation intensity during the control process of the test manipulator.

[0030] S400. Conduct a reliability assessment on the vessel console according to the direct test-related data, the operation intensity-related data, and the discrimination difficulty-related data to obtain the reliability assessment data of the vessel console, so as to guide the design of the vessel console.

[0031] Among them, the direct test task can be a task for directly testing the reliability of the vessel console. The test results obtained through the direct test task include the direct test-related data. The direct test-related data can be the mean time between failures, the failure rate, the failure density, and the failure mode and effect analysis results of the vessel console, which characterize whether the vessel console can work normally during and after the direct test task.

[0032] The indirect test task can be a task for indirectly testing the reliability of the vessel console. The indirect test includes testing the interaction characteristics of the vessel console. It should be noted that the interaction characteristics of the vessel console can characterize the degree of convenience brought to the operator by its design. High interaction characteristics mean that the operator can have a higher operation efficiency during the operation process, reduce the probability of unnecessary operations on the vessel console, and indirectly improve the reliability of the vessel console. While low interaction characteristics mean that the operator has a higher probability of repeated operations or incorrect operations during the operation process, which not only increases the complexity of the operation process but also affects the reliability of the vessel console. Therefore, by testing the interaction characteristics of the vessel console, the reliability of the vessel console can be reflected indirectly, and the comprehensiveness and accuracy of the reliability test results can be improved.

[0033] Similar to directly testing relevant data, the test results obtained through indirect test tasks include indirect test relevant data, which can include discrimination difficulty relevant data and operation intensity relevant data. Among them, the discrimination difficulty relevant data is used to symbolically describe the visual confusion situation and the viewing angle range distribution situation caused by the display state of the ship console in the actual navigation task. For example, the discrimination difficulty relevant data is used to represent the information representation ability of the ship console. A high interaction characteristic means that the operator can quickly and accurately obtain the information represented by the ship console when operating the ship console. The operation intensity relevant data is used to symbolically describe the operation complexity of the ship console in the actual navigation task. For example, the operation intensity relevant data is used to represent the rationality of the component layout and the operation convenience of the ship console. A high interaction characteristic can reduce the unnecessary operations of the operator when operating the ship console.

[0034] A test manipulator is arranged around the ship console. The ship console is within the operable range of the test manipulator. The test manipulator is used to perform test tasks under control to obtain test relevant data. The type of the test manipulator can be any one of configurations such as a two-arm robot, a SCARA robot, a DELTA robot, an industrial robot, and a collaborative robot. The number of test manipulators can be determined according to the actual scenario requirements and can be two or more.

[0035] Specifically, after obtaining the test task for testing the ship console, control the test manipulator to perform a direct test task, and obtain direct test relevant data based on the performance of the ship console on the preset working characteristics during and after the direct test task. In this application, during the execution of the direct test task, the test manipulator is used to replace the manual test of the tester. According to parameters such as the control components, operation amplitude, operation force, operation frequency, and operation times set in the direct test task, control the test manipulator to achieve high-precision and long-term repetitive tests, thereby ensuring the consistency of test conditions during the reliability test and improving the accuracy of the reliability test results. In some embodiments, the control components can include components such as the control lever, control wheel, buttons, and switches of the ship console.

[0036] Furthermore, during the execution of the indirect test task, first collect the display state of the ship console according to the indirect test task. The display state of the ship console represents the information representation ability of the ship console and the current state of the ship console, such as the current angle, current position, and current control state of the control components on the ship console. Analyze the display state of the ship console to obtain the discrimination difficulty relevant data, and obtain the current state information of the ship console based on the current state of the ship console represented in the display state.

[0037] Further, based on the current status information of the vessel console and parameters such as the control components, operation range, operation force, operation frequency, and number of operations set in the indirect test task, determine the specific tasks that the test manipulator needs to perform and control the test manipulator to complete the above specific tasks, so as to complete the indirect test task. During the process of controlling the test manipulator, collect the load data of the test manipulator during the control process to obtain operation intensity-related data, thereby obtaining a data basis for evaluating the component layout rationality and operation convenience of the vessel console.

[0038] It can be understood that in the process of performing the indirect test task in this application, the test manipulator is also used to replace the manual test of the test personnel. The test manipulator is controlled according to the indirect test task to perform the interaction characteristic test, and the operation intensity-related data is obtained based on the load data fed back by the manipulator, so that the interaction characteristics of the vessel console can be quantitatively tested, and the accuracy and reliability of the interaction characteristic test results are improved.

[0039] Further, conduct a comprehensive evaluation based on the obtained direct test-related data, operation intensity-related data, and resolution difficulty-related data to evaluate the reliability of the vessel console and obtain the reliability evaluation data of the vessel console. It can be understood that the direct test-related data characterizes the performance of the vessel console in the preset working characteristics and directly represents the reliability of the vessel console. The operation intensity-related data describes the fatigue accumulation situation of the operator during the actual operation of the vessel due to the design of the vessel console, indicating the rationality of the component layout and operation convenience of the vessel console. The resolution difficulty-related data describes the eye fatigue situation of the operator when the vessel console is actually operated, indicating the information representation ability of the vessel console. The operation intensity-related data and the resolution difficulty-related data jointly reflect the influence of the vessel console on the driving behavior of the operator during the actual driving process. From the indirect perspective of whether the operator will be affected and cause unnecessary operations, it reflects the reliability of the vessel console, thus improving the comprehensiveness and accuracy of the vessel console reliability test results.

[0040] The reliability test method for the vessel console provided in this embodiment evaluates the reliability of the vessel console by controlling the test manipulator to perform direct test tasks and indirect test tasks, and obtaining the execution results of the test manipulator and the relevant data during the execution process. Among them, the direct test task is used to directly test the reliability of the vessel console and determine the performance of the vessel console in the preset working characteristics during and after the direct test task; the indirect test task is used to test the interaction characteristics of the vessel console, and indirectly characterize the reliability of the vessel console by the operation convenience of the vessel console during the actual operation process.

[0041] Compared with the related art, the present application uses a test manipulator to replace a tester to perform reliability tests, improving the repeatability and stability of the reliability tests, reducing the test errors occurring during the tests, and enhancing the test accuracy and precision of the reliability tests. In addition, the present application also performs reliability tests on the vessel console from two different perspectives, improving the accuracy and comprehensiveness of the reliability test results, thereby effectively discovering potential problems existing in the design of the vessel console and enhancing the safety of the vessel console during actual operation.

[0042] As an embodiment of the present application, controlling the test manipulator to execute a direct test task includes: S210. Controlling the test manipulator to operate the control components on the vessel console according to the operation parameters corresponding to the direct test task until the set number of operations in the direct test task is reached.

[0043] Among them, the operation parameters corresponding to the direct test task can be one or more of parameters such as control components, operation amplitude, operation force, operation frequency, and number of operations, so as to stipulate the operation of the test manipulator on the vessel console.

[0044] Specifically, during the execution of the direct test task, the test manipulator is controlled to repeatedly test the corresponding control components according to the set operation amplitude, operation force, and operation frequency until the number of tests reaches the set number of operations. During and after the direct test task, according to the performance of the control component on the preset working characteristics, direct test-related data related to the control component is obtained. According to the direct test-related data of all the control components on the vessel console, the direct test-related data of the vessel console can be obtained, thereby obtaining the test result of directly performing a reliability test on the vessel console.

[0045] As an embodiment of the present application, before controlling the test manipulator to execute the direct test task, it includes: S202. Performing a spatial path planning on the test manipulator according to the control components and operation amplitude corresponding to the direct test task to obtain the direct test path of the test manipulator, so as to control the test manipulator to execute the direct test task.

[0046] Refer to Figure 2aAs shown, where points A1, B1, and C1, as well as points A2, B2, and C2 are points at different positions on the same control component. The control component corresponding to points A1, B1, and C1 is the state of the control component shown in the current status information of the vessel console. The control component corresponding to points A2, B2, and C2 is the state of the control component after operating according to the operation parameters set for the direct test task. Point A1 corresponds to point A2, point B1 corresponds to point B2, and point C1 corresponds to point C2. It can be understood that during the test, there is a spatial path with an arc trajectory between points A1 and A2. Similarly, there are spatial paths with arc trajectories between points B1 and B2 and between points C1 and C2. These spatial paths can all serve as the direct test paths for the test manipulator.

[0047] It should be noted that when controlling the test manipulator to operate on the control component, due to the different contact positions between the test manipulator and the control component, the spatial paths passed by the test manipulator are also different. Therefore, it is also necessary to perform spatial path planning on the test manipulator according to the spatial characteristics of each spatial path, such as whether the spatial path passes through other control components and the length of the spatial path. The direct test path corresponding to the direct test task is usually shorter and only passes through one control component.

[0048] Refer to Figure 2b As shown, where points A, B, and C are points at different positions on the same control component. Since the mechanical strengths and electrical component designs at different positions of the control component are different, due to the different contact positions between the test manipulator and the control component, the directions of the forces exerted by the test manipulator on the control component are different, and the resulting direct test-related data is different, which in turn leads to errors in the reliability test results. In some embodiments, when performing spatial path planning on the test manipulator, strength analysis can be performed on the control component according to conditions such as the shape, external dimensions, and electrical component design of the control component, so as to determine the relatively weak structure in the control component and obtain the operation method that can reflect the reliability of this structure, in order to control the test manipulator and obtain the corresponding direct test-related data, improving the accuracy of the reliability test results.

[0049] Refer to 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, according to the performance of the vessel console in the preset working characteristics, the direct test-related data of the vessel console is obtained, including: S220. According to the electronic signals output by the vessel console during and after the direct test task, the electrical reliability-related data of the vessel console is obtained.

[0050] S230. Detect the reaction impedance of the control components on the vessel console, and obtain the data related to the mechanical reliability of the vessel console based on the reaction impedance.

[0051] S240. Obtain the data related to the direct test of the vessel console based on the data related to the electrical reliability and the data related to the mechanical reliability.

[0052] Among them, the data related to the electrical reliability may include whether the control components on the vessel console can emit electronic signals and whether they can emit correct electronic signals, etc. The data related to the mechanical reliability may include whether the control components on the vessel console are damaged, and one or more of the data such as the stiffness data and the reaction impedance when the control components are operated.

[0053] Specifically, during and after the direct test task, the vessel console is inspected to obtain the data related to the direct test of the vessel console. By operating any control component, it is judged whether the electrical components of the control component are working properly according to the electronic signal output by the control component, so as to obtain the data related to the electrical reliability of the control component. The data related to the electrical reliability of the vessel console can be obtained according to the data related to the electrical reliability of all control components.

[0054] Furthermore, by operating any control component, the data related to the mechanical reliability of the control component is obtained according to the data such as the reaction impedance feedback by the control component during the inspection process. The data related to the mechanical reliability of the vessel console can be obtained according to the data related to the mechanical reliability of all control components.

[0055] Furthermore, according to the data related to the electrical reliability and the data related to the mechanical reliability of the vessel console, it can be determined whether the vessel console can work properly after the direct test task, so as to directly evaluate the reliability of the vessel console.

[0056] Refer to Figure 4 As shown in the figure, as an embodiment of the present application, the test manipulator is controlled according to the current state information of the vessel console and the indirect test task, including: S410. Decompose the indirect test task into any number of subtasks according to the current state information, and perform task planning on any number of subtasks to obtain a subtask sequence.

[0057] S420. Control the test manipulator to test the vessel console according to the subtask sequence to complete the indirect test task.

[0058] Specifically, the current state information represents the control state of the control components on the vessel console. By comparing the current state information with the indirect test task, the control components that need to be operated during the execution of the indirect test task and the corresponding operation amplitudes of each control component are determined. Sub-tasks are formed based on the obtained control components and the corresponding operation amplitudes, and task planning is performed on the sub-tasks according to information such as the operation sequence of the control components in the indirect test task to obtain a sub-task sequence, so as to control the test manipulator to complete the indirect test task.

[0059] As an embodiment of the present application, after decomposing the indirect test task into any number of sub-tasks according to the current state information and performing task planning on any number of sub-tasks to obtain a sub-task sequence, it includes: S412. Perform spatial path planning on the test manipulator according to the control components corresponding to the sub-task sequence on the vessel console to obtain the indirect test path of the test manipulator, which is used to control the test manipulator to execute the indirect test task.

[0060] Specifically, the sub-tasks include the control components that need to be operated during the execution of the indirect test task and the corresponding operation amplitudes of each control component. According to the positions and external dimensions of the control components before and after the operation, the spatial path passed by the test manipulator during the operation is determined to obtain the indirect test path, so as to control the test manipulator. Compared with the direct test path, the indirect test path corresponding to the indirect test task is usually longer and passes through multiple control components.

[0061] Refer to Figure 5 As shown, as an embodiment of the present application, the reliability evaluation data is obtained through the following methods: S510. Compare the electrical reliability-related data with the electrical reliability threshold to obtain the electrical reliability test result.

[0062] S520. Compare the mechanical reliability-related data with the mechanical reliability threshold to obtain the mechanical reliability test result.

[0063] S530. Compare the resolution difficulty-related data with the resolution difficulty threshold to obtain the resolution difficulty test result.

[0064] S540. Compare the operation intensity-related data with the operation intensity threshold to obtain the operation intensity test result.

[0065] S550. Perform weighted calculation on the electrical reliability test result, the mechanical reliability test result, the resolution difficulty test result, and the operation intensity test result to obtain the reliability evaluation data.

[0066] Among them, the data related to the discrimination difficulty includes the brightness data, color data, and discrimination accuracy data of the display screen of the vessel console; the data related to the operation intensity includes the torque data, operation frequency, and operation time of the test manipulator during the control process.

[0067] Specifically, the electrical reliability threshold may include the electrical signal amplitude and frequency, etc., for judging whether the manipulation component outputs electrical signals normally. The mechanical reliability threshold may include the reaction impedance threshold and the stiffness threshold, for judging whether the manipulation component can work normally. According to the electrical reliability test results and the mechanical reliability test results, the performance of the vessel console in the direct test task can be obtained.

[0068] Furthermore, a discrimination difficulty threshold is set for the data related to the discrimination difficulty. Exemplarily, the discrimination difficulty threshold may be based on the minimum distinguishable brightness, color difference threshold, and discrimination accuracy threshold when the human eye observes the vessel console, etc. If the display screen does not meet any of the discrimination difficulty thresholds, the tester may not be able to accurately identify the control information displayed on the display screen, which may further cause the operator to be unable to operate the vessel console correctly, thereby indirectly affecting the reliability of the vessel console.

[0069] Furthermore, an operation intensity threshold is set for the data related to the operation intensity. Exemplarily, the operation intensity threshold may be the maximum holding torque, maximum pressing force, operation frequency threshold, and operation time threshold when the operator operates the vessel console, etc. Among them, the maximum holding torque and the maximum pressing force reflect the operation requirements of the vessel console for the operator, while the operation frequency threshold and the operation time threshold reflect the fatigue conditions caused by the vessel console to the operator. Unreasonable design will increase the risk of incorrect operation by the operator, indirectly affecting the reliability of the vessel console.

[0070] Furthermore, the test result may be evaluation data related to the relevant data.
