Research On Layout Design And Evaluation Optimization Of Human-machine Interface For Cabin

Cabin is the human-computer interaction node of control,human-machine interface composes of a large number of display,control components,with complex structure.The reasonable layout design of human-machine interface of cabin,can provide comfortable operating postures,good vision and pleasant atmosphere to operators,and help to give full play to the operators’ working efficiency.Therefore,from the angle of ergonomics,layout design and evaluation optimization has very important significance.But the current research on layout problem is studied from the viewpoint of engineering practice,take the improvement of utilization rate of space and materials as the research target,and cognitive characteristics and perceptual image requirements are seldom be considered in cabin layout design.Cabin evaluation is given priority to qualitative analysis,or take single factor,partial design as research object,so there is lack of systematic quantitative research.Aiming at these problems,under the support from project of CNPC Logging CO.,LTD.“logging truck industrial design” and key projects of national 863 project “4500 meters manned submersible design and key technology research: the cabin layout optimization design method research”,the key technology is studied around the layout design and evaluation optimization of human-machine interface for cabin.The main content and innovation points of this paper are as follows:(1)From the perspective of industrial design,the layout design and evaluation optimization problem of human-machine interface of cabin was decomposed,described and solved.And the research method framework of layout design and evaluation optimization of human-machine interface of cabin was put forward.Including: the human-machine interface spatial layout design method based on genetic-ant colony algorithm;the human-machine interface color layout design method based on hierarchical interactive genetic algorithm;the layout ergonomic comprehensive evaluation method containing visual ergonomics,operating comfort and human reliability analysis;the color image evaluation method based on gene expression programming algorithm.(2)In terms of spatial layout design,on the basis of Wickens information processing model,the cognitive model of human-machine interface for cabin was established.Through cognitive model to describe the process of human understanding,human cognitive characteristics were studied,and the layout design principles were summarized.According to each principle respectively,the mathematical model and objective function of layout optimization were built.The problem of solving layout scheme was transformed into a combinatorial optimization problem,and genetic-ant colony algorithm would be used to solve.The expression form of fitness function,pheromone and heuristic information for the layout optimization was studied.The solution of layout scheme was generated by genetic algorithm,and they would be translated into initiatory pheromone,then ant colony algorithm would calculate precisely by the optimization mechanism of positive feedback.The whole process realized the algorithmization of artificial optimization process,with good optimal performance and time performance.(3)In terms of color layout design,the comprehensive factors influenced on color image were discussed,such as color value,number,area ratio,and location distribution form.125 color samples were divided by KJ method,and the semantic difference method was used to survey the relationship between color samples and image semantic “dynamic – quiet”.The color image evaluation of adjectives “dynamic – quiet” was divided into three kinds of gray classes: dynamic,neutral,quiet,and the grey clustering method was used to predict the color image tendency of human-machine interface painted with multicolor.Through color image position value to obtain color combinations,a feasible solution of color database was built.The global search capability of interactive genetic algorithm was used to carry out color combination,and hierarchical search was used to reduce the searching space and speed up convergence.(4)In terms of layout ergonomic evaluation,from the perspective of ergonomics,to evaluate whether the layout of display,control component within the cabin was in line with the human physiological structure and psychological characteristics,and whether minimized the human error probability as much as possible.On the basis of the analysis of the human vision characteristics,eye ellipse and H point from automotive vision design were improved,eye ellipsoid was used to locate the human body model quickly,and visibility analysis and main operating postures simulation were analyzed by CATIA software.By Kane dynamic model and NASA strength mode,the joint torque was brought into the joint comfort evaluation,and the upper limb’s operating comfort would be used to evaluate layout scheme.In view of the application area of petroleum industry,the common performance conditions in CREAM were improved,and with analytic hierarchy process to determine their weights,the quantitative evaluation of human reliability of cabin was realized by grey correlation analysis method.(5)In terms of color image evaluation,from the perspective of color psychological effect,to evaluate whether the color design could play reasonable color regulating function,and whether could meet the demand of users’ perceptual image.The color image evaluation experiment between environmental color sample of cabin and image semantics was carried out by semantic differential method.Under the premise of keeping the main information of data,the experimental data was preprocessed by factor analysis,which could get rid of the correlation among data,and reduce the data dimension effectively.The entropy weight method was used to determine the objective weight of each color factor.With 125 groups of evaluation data as the data base of prediction model,gene expression programming algorithm realized the automatic modeling of complex function,and built the best fitting function between the factor score and comprehensive color image of environmental color sample of cabin.It provided a rapid method to evaluate color image.Through the above research work,a set of theory and method system suitable for layout design and evaluation optimization of human-machine interface for cabin was formed eventually,a prototype system was developed,and combining with the case of human-machine interface layout of oil drilling control room for verification.The proposed method enriched and improved the theory system of ergonomic research on cabin,which had practical value for improving ergonomic performance of cabin.
