Space Station Payload Cabinet Interface Information Organization And Design Practices

The space station payload cabinet is an important vehicle for maintaining the operation of the space station system,the daily life of the astronauts,and the normal conduct of a large number of space experiments.As an important part of the space station and other large spacecraft.The payload cabinets provide standard mechanical,electrical,thermal and environmental interfaces for each payload unit to ensure the reliable operation of the payload units,and a large number of manipulators are arranged on the operator interface.Which is an important medium for astronauts to control the cabinets to conduct relevant experiments and maintain the normal operation of the space station.However,before the completion of the Chinese Tian Gong space station,most of the load cabinets deployed on it are designed and studied from the functional and structural levels,and there are still deficiencies in the interface of the cabinets.Such as complicated operation information and undisciplined layout.In this research,we design and study the cabinet interface through information organization theory.Construct a design model for the information organization of the load cabinet interface,and validate the method by using design practice and eye-movement experiments to provide a new method for the design of the space station load cabinet interface.This paper focuses on exploring the design model of information organization of space station load cabinet interface from the perspective of information organization theory,and solving the problems of unclear logical relationship and lack of aesthetic interface of present-day load cabinets.The paper is mainly divided into three parts:(1)To analyze the design of special cabinets for space station payload cabinets,analyze the product modeling style,related human-machine requirements,interface design points,etc.And identify the relevant issues in the interface design of payload cabinets,and at the same time,interpret the information organization theory to explore the common points in information organization and interface design.(2)Integrate the information organization theory with the interface design process.Build a space station payload cabinet interface information organization design model,from the five levels of information analysis,selection,revealing,storage,and service.Distinguish the selection of single information,arrangement of multiple information,and optimization of multiple information,and establish the hierarchical relationship of model selection layer-organization layer-system layer.In the information analysis link,the information characteristics are ordered by analyzing all the information in the interface;in the information selection link,the information is refined by selecting the required information;in the information disclosure link,the operation is clarified by arranging and combining the information in the interface;in the information storage link,the information quality is optimized by optimizing the information carrier;in the information service link,the interface is made friendly by optimizing the cabinet interface as a whole.In the information service link,the overall interface of the cabinet is optimized to achieve a friendly interface.(3)Taking the KJZ human system experimental load cabinet product as a case,the reliability and validity of the interface design under the guidance of this method model are verified by using the eye-tracking experiment.This paper takes information organization method as the theoretical basis,integrates it into the product interface design process,and creatively constructs an information organization design model for the space station payload cabinet interface.A rational constraint is constructed for the interface design process,and the validity and reliability of the method are verified through product design practice and eyemovement experiments.In terms of research significance,this is not only a supplement to the current product interface design method,but also a multi-disciplinary expansion of information organization theory,providing a reliable methodological reference for the study of load cabinet interface design and contributing to the national manned space program in the field of industrial design.
