The work aims to integrate human-computer interaction analysis with the FBS design model to derive user interaction paradigms and prototype designs in remote control processes and construct a human-computer interaction process for remote control systems, ultimately forming a design scheme for remote control system of crane. Firstly, based on user research and experiments, the human-computer interaction characteristics of existing crane control systems were analyzed, and a human-computer interaction model for the remote control system of crane was constructed. Secondly, by combining functional requirements and user behavior characteristics with the FBS (Function-Behavior-Structure) design analysis method, the structural components of the remote interaction system for crane were derived, and the specific solutions were designed based on human-computer interaction research. Finally, ergonomic simulation analysis and verification were conducted with Creo Manikin. The design factors are determined and the design scheme is developed for the remote control system of crane through human-computer interaction analysis and FBS design model, which holds theoretical significance and practical application value for the design and development of remote operation systems for engineering machinery.
