Study On Agricultural UAV Product Design Based On SA Theory

With the rapid development of China’s economic strength and scientific power in recent years,the country pays great attention to the combination of mechanization and information technology,agricultural UAVs,as an important part of agricultural machinery,have also been developing rapidly under the strong support of the state,but they need to be strengthened in terms of spraying technology.With the continuous maturity and development of AI,5G,electronic technology and display technology,the control of agricultural UAVs has evolved from being controlled by buttons through large ground stations to completing the control of UAV operations through digital interfaces.Due to the complexity of the external environment and the complexity of the task operations,the interface needs to display the flight status of agricultural UAVs and the real-time status of equipment operation in real time.How to scientifically design the control interface design and interface information presentation form,so that the operator can improve situational awareness,and reduce the aviation accident caused by decision-making errors or inefficient decision-making has become a key issue in the interface research.Most of the existing research is focused on theoretical studies or in other fields,and few scholars have applied to interface design practice.Therefore,based on the SA theory,the thesis is a study on the design of agricultural UAVs and their control interfaces,and the design of agricultural UAV products and control interfaces is optimized based on the problems on agricultural UAV products and the SA problems in their interfaces.The thesis firstly investigates the SA theory and SA in the human-computer interaction of the control interface of agricultural UAVs;secondly,it composes,analyzes and deconstructs agricultural UAVs and their control interfaces,and finds out the problems of users in using the products and the problems of SA in the control interfaces through user research,and summarizes the pain points and needs of users for the products and interfaces,and on this basis,it synthesizes Based on the three levels of SA theory,the design strategy of agricultural UAV and the optimization design strategy of its control interface are proposed.Finally,under the guidance of the design strategy,the product design of the agricultural UAV and the optimized design of the control interface of the agricultural UAV under different situations in the spraying process were produced,and the feasibility and effectiveness of the optimized design were verified by SUS usability scale and eye-movement evaluation experiment.The research results provide design ideas and methods for the optimal design of human-machine interface based on situational awareness theory,and provide theoretical support and experimental basis for the design and optimization of the control interface of agricultural UAVs in the future.The thesis consists of 96 figures,23 tables,and 95 references.
