Description

Technical Field

[0001] The present invention relates to the field of ship ergonomics design and evaluation, and in particular to an ergonomics evaluation method and system for an integrated control console of a high-speed ship. Background Art

[0002] Existing technologies for the design of integrated control consoles for high-speed vessels primarily rely on physical prototype trials and empirical ergonomic evaluations, which present significant limitations. Traditional methods typically employ static human models for simulation analysis, failing to fully consider the impact of dynamic operating conditions such as hull roll and pitch on human posture during actual operation. This results in discrepancies between the height of the control panel and the layout of display units and ergonomic requirements. For example, simulation data shows that a P95 height soldier cannot reach key control panel buttons while standing upright, requiring them to continuously bend at the waist to operate, which can lead to musculoskeletal injuries. Furthermore, existing evaluation processes often focus on a single dimension, such as static dimensional compliance, lacking systematic analysis of multi-position collaborative operation effectiveness, software interface interaction logic, and environmental adaptability. Optimization solutions are often limited to local adjustments. Repeated revisions to physical prototypes rely on subjective judgment and fail to effectively integrate virtual simulation data, such as joint load parameters, with physical test results, such as the rate of exceedance of dynamic operating angles. This results in long design iteration cycles and high costs. Although some methods refer to the national military standard GJB 2873-1997 for size comparison, a full-process standard compliance verification mechanism has not been established from virtual model verification, prototype testing to semi-physical environment simulation, making it difficult to ensure the overall compliance of key indicators such as human-machine adaptability and visual accessibility.

[0003] Therefore, there is an urgent need for an evaluation method that integrates multi-stage data-driven and covers all dimensions of human-machine relationships to solve the problem of human-machine ergonomics collaborative optimization in the design of high-speed ship consoles.

[0004] Therefore, the present invention can construct a demand-, function-, and task-oriented semi-physical ergonomics evaluation system for the integrated console through the semi-physical ergonomics evaluation of the integrated console, guided by the actual tasks of the integrated console. The standards, methods, and concepts in the ergonomics evaluation system are integrated into each stage of the design, development, production, assembly, use, and maintenance of the integrated console, thereby making the integrated console safer, more comfortable, healthy, efficient, and economical during use, and fundamentally improving the sustainable combat capability in all environments and throughout the entire cycle.

[0080] The purpose of the present invention is to provide a method and system for evaluating the ergonomics of a high-speed vessel integrated control console, aiming to improve the ergonomics adaptability of the high-speed vessel control console.

[0081] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0082] Reference Figure 1 , showing a method for evaluating ergonomics of a high-speed vessel integrated control console according to an embodiment of the present application, the method comprising the following steps:

[0083] Step S1. Perform an ergonomic simulation assessment. Based on the integrated console CAD drawings, a 3D virtual simulation model of the console is constructed using UG modeling software. This model is then imported into the JACK ergonomic analysis platform for ergonomic analysis. This 3D virtual simulation model simulates the human-object-environment interaction and generates operational reach, joint load parameters, and ergonomic dimension deviation warning data.

[0084] Specifically, the integrated control console primarily consists of navigation control and operating areas, auxiliary control areas, and navigation radar. Based on the integrated control console's CAD drawings, a virtual simulation model was constructed using UG modeling software. Human-machine efficiency analysis and research were conducted on the virtual simulation model using JACK software. Data from the ergonomic evaluation of the integrated control console revealed that a P95 male operator must bend over to operate the console; when standing upright, their palms cannot reach the buttons and screen. Bending the waist forward 15° and rotating it 15° to the right allows access to the seventh control panel and pitch setter. Bending the waist forward 30° and rotating it 30° to the right allows access to the sixth, seventh, and eighth control panels. Bending the waist forward 85° (extreme position) and rotating it 40° to the right allows access to the fifth, sixth, and seventh control panels, as well as some buttons on the broadcast control box and the left and right sides of screen 2. In extreme positions, the screen can be operated with one hand. Bending the waist forward 30° and rotating it 30° to the left allows access to the sixth, seventh, and eighth control panels, as well as all buttons and keyboards on the broadcast control box. Bend the waist forward 85° (extreme position) and rotate it 40° to the left (extreme position) to access the ⑤, ⑥, ⑦, and ⑧ control panels, as well as all buttons on the broadcast control box, the keyboard, and both sides of the screen. In extreme positions, the screen can be operated with one hand. Soldiers with a height of P95 in positions A and D need to bend over to operate. The control surface should be raised, moved closer to the screen, or a seat should be provided to reduce the risk of lumbar injury.

[0085] Preferably, the step S1 includes the following sub-steps: Figure 2 As shown:

[0086] S11. Based on the integrated console CAD drawings, a three-dimensional virtual simulation model including navigation parts, radar parts, and auxiliary parts is constructed in the UG modeling software to simulate the cockpit space layout and the hull roll and pitch conditions;

[0087] S12. The P95 male human biomechanical model is introduced into the JACK ergonomic analysis platform, and the natural operating height reference value H in the upright state is set based on the GJB2873-1997 standard. 基准 =900mm;

[0088] S13. Detect waist bending angle and horizontal rotation angle The combined operation state maps the operation range according to the following rules:

[0089] when =15° and =15°, the operating range covers the main control panel and pitch adjustment device at the navigation command position;

[0090] when =30° and =30°, the operating range extends to the combined control panel at the navigation radar and all functional interfaces of the broadcast terminal;

[0091] when ≥85° or When the angle is ≥40°, it is determined to be an extreme operation state, and the operation range is reduced to some functional interfaces of the emergency control panel, edge display unit and broadcast control terminal, and only one-handed operation is supported;

[0092] S14. Calculate the operating surface height ΔH=H 基准 -H 实测 , where H 实测 The actual height of the operating surface when the palm of the P95 male human biomechanical model touches the core control panel in the virtual environment;

[0093] S15. When the navigation command position and auxiliary command position are detected When the continuous operation behavior is ≥30°, the optimization instructions of the operation surface lifting amount ΔH ≥ 50mm and the display unit forward movement amount ΔL ≥ 150mm are generated.

[0094] In summary, Step 1, through comprehensive console ergonomics simulation assessment, can simulate the relationship between people (captain, deputy captain, radar team leader, etc.), objects (console), and the environment (driver's cab). This allows for early detection of potential safety, efficiency, health, and comfort risks to the console caused by issues such as human-machine size deviations and human-machine relationship confusion. This not only improves design efficiency and shortens the R&D cycle, but also minimizes the cost of subsequent modifications and maintenance, avoiding the significant risks of possible major modifications and redesigns.

[0095] Step S2. Conduct ergonomic verification of the prototype: construct a wooden prototype and measure its static dimensions and dynamic operating parameters. Compare the measurement results with the GJB 2873-1997 standard and generate an optimized parameter set for the prototype based on the user experience scale.

[0096] Specifically, the ergonomics evaluation of the integrated control console prototype aims to clarify the dimensional relationships between people (captain, deputy captain, radar monitor), objects (the integrated control console and various functional components of the bridge), and the environment (the bridge), as well as the overall user experience. This will provide a basis and direction for the subsequent ergonomic optimization design of the semi-physical prototype. The integrated control console primarily consists of navigation control and operation areas, auxiliary control areas, navigation radar areas, and temporary areas. The prototype consists of a wooden molded frame structure, spray-painted gray, and inlaid with an LCD screen (the interface is simulated using a static image), a physical panel mockup, a physical handle mockup, a physical phone mockup, and a physical handwheel mockup. The entire prototype is non-functional and serves only to demonstrate the overall form, the actual dimensions of its components, and their spatial relationships.

[0097] (1) The prototype of the integrated control console was measured using tools such as a tape measure, ruler, caliper, rangefinder, inclinometer, and positioner to obtain the actual static (length, width, height, angle) and dynamic (limbs, field of view) dimensions of the prototype. The data were compared with relevant human-machine engineering standards such as GJB 2873-1997 “Human-machine engineering design guidelines for military equipment and facilities” to determine whether the human-machine dimensions of the prototype met the requirements.

[0098] (2) Let users simulate the operation of the prototype of the integrated driving console in real life. Users fill in the user experience scale based on their sensory cognition of the simulated operation, thereby obtaining the user's overall cognitive feeling of the prototype of the integrated driving console, and judging whether the human-computer experience of the prototype meets the requirements.

[0099] Preferably, the step S2 includes the following sub-steps: Figure 3 As shown:

[0100] S21. Build a wooden prototype, including a frame structure for the navigation control unit, navigation radar unit, auxiliary control unit, and temporary units. The surface is painted gray and inlaid with a simulated display unit, a physical operation panel, and a control handle.

[0101] S22. Perform static dimensional measurements using a laser rangefinder and digital inclinometer to obtain the actual measured values ​​of the prototype's length, width, height, and installation angle, and calculate the relative deviation from the design values. ,

[0102] ;

[0103] in, 、 、 are respectively the measured length, width and height of the wooden prototype; 、 、 are the design values ​​of the CAD drawings respectively; When the ratio is >5%, it is judged as out of tolerance;

[0104] S23. Perform dynamic ergonomic verification by using an inertial motion capture system to record the forearm tilt angle of the user when operating the broadcast control terminal. and wrist rotation angle ,when >45° or Generates the tilt correction value of the operation panel when it is >25° =5°~10°;

[0105] S24. Conduct a user experience assessment, having experienced users perform simulated combat readiness and navigation missions, and assign ratings based on three dimensions: operational comfort, visual accessibility, and task continuity. Operational comfort is assessed based on hand contact pressure distribution and limb movement fluidity, with a weight of 0.4. Visual accessibility is assessed based on the main display unit's field of view coverage and interface element recognition, with a weight of 0.3. Task continuity is assessed based on the number of interruptions and false trigger rate for multi-position coordinated operations, with a weight of 0.3.

[0106] S25. Comprehensive static dimensional deviation , dynamic angle exceeding standard rate and total score of user experience, generate the initial prototype optimization parameter set, including: operating surface height adjustment =ΔH×0.8+ ×0.2; display unit tilt correction , is the nominal sight distance; the control handle spacing is enlarged .

[0107] Among them, in the sub-step of S23 on dynamic ergonomics verification, the dynamic angle exceeding rate index represents the forearm inclination angle during user operation. or wrist twist angle The percentage of operations exceeding the threshold to the total number of operations is used to evaluate ergonomic design defects. For example, if the dynamic angle exceeds the standard rate > 20%, it means that the operating posture is prone to fatigue and the panel tilt angle needs to be adjusted, which is the above-mentioned =5°~10°.

[0108] In the user experience evaluation substep S24, weights of 0.4, 0.3, and 0.3 are assigned to operational comfort, visual accessibility, and task coherence, respectively. This serves to quantify priorities. The weight of 0.4 for operational comfort is given because physical fatigue directly impacts operational efficiency, and therefore, this dimension has the highest priority. Interface visibility is crucial for task execution, but slightly less so than operational comfort, so a weight of 0.3 is assigned to visual accessibility. The smoothness of collaborative operations impacts overall task completion time, so a weight of 0.3 is assigned to task coherence.

[0109] In S25, the total user experience score is a weighted average that combines multi-dimensional data into a single indicator, namely the total score U. The specific formula is: U = 0.4 × operating comfort score + 0.3 × visual accessibility score + 0.3 × task consistency score. The range of U is usually 0 to 100 points. When U ≥ 80 points, it is judged as qualified, indicating that the prototype design meets the ergonomic requirements; when U < 80 points, the corresponding prototype needs further optimization. =ΔH×0.8+ ×0.2, for example, if ΔH=10mm, =5°, then =0.8×10+0.2×5=9mm. Display unit tilt correction amount According to the height of the adjusted operating surface With a nominal viewing distance of 500 mm, calculate the display unit tilt correction to ensure that the viewing angle is consistent with the natural visual range of the human eye, usually 15°~30°. For example, if =9mm, then =arctan(9 / 500)≈1.03°. Control handle spacing expansion Indicates handle spacing adjustment and size deviation Proportional, For every 5% threshold exceeded, the spacing is increased by 10 mm. For example, if =7.5% (2.5% deviation), then =10×(7.5 / 5)=15mm.

[0110] In summary, step 2, through the ergonomics evaluation of the integrated console prototype, i.e., the wooden prototype, can perform ergonomic dimension verification for the integrated console of a specific target volume based on the overall senses of actual users, simulate the actual relationship between man and machine, and preliminarily build an ergonomics evaluation system for the integrated console prototype oriented to needs, functions, and tasks, providing a very important basis and specific direction for the ergonomics optimization design of the semi-physical model in the later stage.

[0111] Step S3. Conduct a comprehensive hardware-in-the-loop evaluation, evaluating the hardware-in-the-loop model in seven dimensions: human-machine applicability, human-machine usability, human-machine relationship, human-machine task, human-machine environment, execution software interface, and user psychology and overall experience. Output a comprehensive evaluation report and a structural optimization plan.

[0112] Specifically, the ergonomics evaluation of the integrated console hardware-in-the-loop model requires a multi-level evaluation model that progresses from simple to complex, from part to whole, from people to machines, and from relationships to tasks. Referring to this process, different methods are used to evaluate the following:

[0113] (1) Human-machine suitability evaluation of the semi-physical model of the integrated cockpit console. Using measurement and comparison methods, the static dimensions of the semi-physical model are numerically compared with the standard human body dimensions of the appropriate percentile of the national military standard to evaluate the suitability of the user's physiological parameters for the semi-physical model of the integrated cockpit console.

[0114] (2) Human-computer usability evaluation of the semi-physical model of the integrated driving console. This evaluation uses the input method, simulation method, measurement method, and comparison method. The dynamic range (including visual dynamic range and behavioral dynamic range) of the user when operating the semi-physical model of the integrated driving console is numerically compared with the vertical and horizontal visual ranges and vertical and horizontal limb activity ranges specified in the national military standard to evaluate the user's visual visibility, limb accessibility, and sensory recognition.

[0115] (3) Human-machine relationship evaluation of the semi-physical model of the integrated control console. This evaluation uses mapping, experimental verification, and analytical methods. Based on the mapping relationship between display and operation, the correlation, compatibility, and consistency between the navigation radar display, integrated information interaction display 1, multi-function information display 1, integrated information interaction display 2, and multi-function information display 2 and the navigation command and control position, radar position, and maneuver position operation are evaluated.

[0116] (4) Human-machine task evaluation of the integrated driving console semi-physical model. This evaluation used experimental verification methods, multiple linear regression analysis, and algorithms. The task process and requirements were sorted out, and the user character settings of each combat position in the branch were set. The time, accuracy, and difficulty of single task items and overall task items were extracted. Through multiple regression analysis, the task completion measurement value was obtained. The task completion brightness value was compared with the weighted mean to evaluate the task completion degree of each combat position user when using the integrated driving console semi-physical model.

[0117] (5) Human-machine environment assessment of the semi-physical model of the integrated control console. This assessment uses measurement, analysis, and comparison methods to simulate the sound and light environments of users in actual work scenarios, measure the values ​​of each individual environment, and compare the values ​​with the environmental parameters of the national military standard to evaluate the environmental adaptability of the integrated control console to users of navigation command, auxiliary command, and navigation radar operations.

[0118] (6) Software interface evaluation of the semi-physical model of the integrated control console. This evaluation uses experimental, measurement, and comparative methods to collect, experiment, and analyze the icons, text, symbols, and colors of the ship system software interface, power system software interface, operation and control system software interface, main power system software interface, and integrated control console software interface at the cognitive, interactive, and feedback levels, and conduct software interface evaluation of the semi-physical model of the integrated control console.

[0119] (7) User psychology and comprehensive experience evaluation of the semi-physical model of the integrated cockpit console. This evaluation uses experimental and scale methods. The information type and quantity of the semi-physical model of the integrated cockpit console are extracted, and the cognitive load of the information encoding capacity of the semi-physical model of the integrated cockpit console on the user is experimentally analyzed. At the same time, based on the user's experience in the complete task cycle, the comprehensive human-machine quality of the semi-physical model of the integrated cockpit console is evaluated through sensory perception.

[0120] Preferably, the step S3 includes the following sub-steps: Figure 4 As shown:

[0121] S31. Perform an ergonomics assessment. Using measurement and comparison methods, compare the static dimensions of the semi-physical model with the P50-P95 percentile human dimensions specified in the GJB 2873-1997 standard. Generate a physiological parameter compatibility report. In S31, use a laser rangefinder to measure the height of the navigation control panel, the installation height of the radar display unit, and the horizontal spacing of the auxiliary combat position control handles. Collect at least three sets of data and average the values. Compare these measurements item by item with the P50-P95 percentile human elbow height in sitting position (P95 male: 650mm-720mm) and vertical grip height in standing position (P95 male: 1900mm-2050mm) specified in GJB 2873-1997. For example, if the actual height of the navigation control panel is 680mm, compared to the P95 elbow height range (650mm-720mm), it is determined to be suitable. For example, if the actual height of the radar display unit is 2100mm, exceeding the P95 upper limit of standing grip (2050mm), a correction parameter is generated to "move the display unit down 50mm." A tabular report is generated, noting any deviations. For example, if "the distance between the auxiliary combat position handles is measured at 400mm, exceeding the standard range of 350mm-380mm, a deviation of 5.3%," an adjustment solution is recommended, such as "reducing the distance to 370mm ± 5mm."

[0122] S32. Perform a human-computer usability assessment. Using input and simulation methods, the user's visual and limb dynamic ranges during operation are measured and compared with the vertical and horizontal visual ranges and limb ranges specified in GJB 2873-1997. Correction parameters for visual visibility, limb accessibility, and sensory perceptibility are generated. In S32, a ±15° roll of the hull is simulated on a six-degree-of-freedom platform. An eye tracker is used to record the user's vertical viewing angle when observing the navigation radar display unit to determine whether it exceeds the ±30° vertical visual range specified in GJB 2873-1997 for the upright position. A motion capture system is used to measure the user's forearm extension radius when operating the broadcast control terminal and compare it to the standard horizontal range of 500mm-700mm. If the measured extension radius is 750mm, an optimization command to "move the control panel inward 50mm" is triggered. Under an ambient illumination of 300Lx, the symbol recognition distance of the multi-function information display unit is tested. If the standard requires that the symbol be recognizable when the distance is ≥1.5m, and the actual measurement is 1.2m, a suggestion of "enlarge the symbol size by 20%" is generated.

[0123] S33. Perform a human-machine relationship assessment. Using mapping and experimental verification methods, establish a mapping relationship matrix between the navigation radar display unit, the integrated information interaction display unit, the navigation command position, and the radar position operation panel. Verify the correlation, compatibility, and consistency between the display and operation. Trigger a layout optimization instruction when the mapping relationship deviation exceeds a standard threshold. In S33, verifying the correlation, compatibility, and consistency between the display and operation specifically includes: verifying the correlation based on the matching relationship between the navigation command position operation instruction sequence and the navigation radar display unit information update sequence, and calculating the correlation coefficient. :

[0124] ;

[0125] in, For the The type code of the sub-operation instruction, For the The type code of the display information update. is the number of sampling times and ≥50; when When the correlation is less than 0.7, it is determined to be insufficient; the response time Δt from the input of the command on the radar operation panel to the completion of the feedback update of the integrated information interaction display unit is measured to verify the consistency; when Δt>300ms, it is determined to be excessive consistency; the matching degree between the physical layout of the operation panel and the logical layout of the display interface is quantified by the spatial mapping algorithm to verify the consistency. The calculation is as follows:

[0126] ;

[0127] in, is the number of comparable functional groups, For the operation panel The measured distance between the function keys, To display the design spacing of the corresponding functional blocks on the interface, =500mm; when When the correlation, compatibility, and consistency verification result is less than 0.9, it is determined that the consistency does not meet the standard. When any one of the correlation, compatibility, and consistency verification results is less than the standard, the layout optimization instruction is triggered according to the following priorities: the first priority corresponds to the function mapping group with insufficient correlation; the second priority corresponds to the interactive link with excessive compatibility; the third priority corresponds to the layout area with insufficient consistency.

[0128] S34. Perform human-machine task evaluation, using experimental verification and multivariate linear regression analysis to extract the time and accuracy data for each user at each combat position performing both single and overall task items. This weighted task completion metric is then compared with the preset weighted mean to generate a task process optimization plan. In S34, the weighted task completion metric specifically includes: , Accuracy stability factor , Difficulty Adjustment Factor , construct an orthogonal regression model without multicollinearity, corresponding to the measurement value ;

[0129] ;

[0130] in, and The benchmark operation time and the measured time are respectively; For operational accuracy; is the task complexity weight; define the qualified lower limit , warning threshold ,in and are the mean and standard deviation of the historical completion of similar tasks respectively; <15%, shorten >1.1 The operation link of the task item; when <0, adjust <0.8 Task item interface element layout; when Less than 0.2, decomposition >1.3 high complexity task items.

[0131] S35. Perform a human-machine environment assessment, simulating the acoustic and light environments of actual user work scenarios. Sound pressure levels and illuminance parameters are measured, numerically compared with the environmental parameters specified in GJB 2873-1997, and an environmental compatibility analysis report is generated. In S35, noise sources are placed in the cockpit model, with a frequency range of 63Hz-8kHz. An integrating sound level meter is used to measure the equivalent sound pressure level at the navigation control area. If the measured sound pressure level is 68dB(A), exceeding the GJB 2873-1997 limit of 65dB(A), a plan is generated to "install 5cm thick sound-absorbing cotton around the combat position." A illuminance meter is used to measure the horizontal illuminance in the radar operating area. If the measured illuminance is 280Lx, compared to the standard of 300-500Lx, a command is triggered to "add two sets of 5000K color temperature LED fill lights." The display unit's image jitter amplitude is tested under 5Hz-30Hz random vibration. If the jitter is greater than 0.5mm, the optimization item "Install a shock-absorbing bracket with a damping coefficient ≥ 0.3" is generated.

[0132] S36. Perform software interface evaluation, conducting experimental testing of the icons, text, symbols, and colors of the ship system, power system, and operation and control system software interfaces at the cognitive, interactive, and feedback levels, and outputting interface usability optimization recommendations. In S36, the software interface evaluation specifically includes: testing the icon recognition of the ship system, power system, and operation and control system software interfaces, recording the user's first recognition time and number of false touches of key icons in a simulated operating environment, and generating icon layout optimization recommendations; testing the readability of text and symbols in the main power system and integrated control console software interfaces, analyzing whether their size, font, and contrast meet the human-computer interaction design requirements of GJB 2873-1997; verifying the visual distinction of the colors of each system software interface, and generating color adjustment solutions based on the colorimetric standards specified in GJB 2873-1997; and testing the interactive feedback response time when the user operates the interface, testing whether the delay from command input to system update meets the preset interactive performance requirements.

[0133] S37. Perform a user psychology and comprehensive experience assessment, quantifying user cognitive load and user experience data throughout the complete task cycle using a scale method, and generating a comprehensive human-machine performance rating report. In S37, performing the user psychology and comprehensive experience assessment specifically includes: collecting users' subjective ratings of the integrated dashboard information encoding capacity using a scale method, analyzing the impact of the type and amount of simultaneously displayed information on cognitive load; based on operation records throughout the complete task cycle, calculating the frequency and number of interruptions in user multitasking and generating a task flow simplification plan; combining sensory experience scale data to evaluate users' comprehensive evaluation of the dashboard's operational smoothness and environmental comfort, and outputting a comprehensive human-machine performance rating report; and triggering information architecture optimization and human-machine layout adjustment processes when either the cognitive load score or the sensory experience score falls below a preset qualifying threshold.

[0134] The evaluation results of S31-S37 were integrated to generate the comprehensive evaluation report and structural optimization plan. Here is an example of the evaluation report: Regarding the navigation control area, the operating panel height is 680mm (standard P50-P95 elbow height is 650-720mm), which is acceptable. The main display unit tilt angle is 15° (standard 10°-20°), which is acceptable. Regarding the radar area, the horizontal spacing of the combined control panels is 420mm (standard 350-400mm), exceeding the tolerance by 5%. It is recommended to reduce it to 380mm. The display unit viewing angle deviation is -35° (standard ±30°), and it is recommended to move it down 80mm.
