多功能轮椅的研究-控制系统及框架结构设计

Research on Multifunctional WheelchairControl System and Frame Structure DesignAbstractIn this paper,the research background,purpose,significance and current situation of themultifunctional intelligent wheelchair are described,and then the core problems and keytechnologies are summarized.According to the main functional requirements of themulti-functional intelligent wheelchair,the mechanical structure and control system of thewheelchair are studied and designed in this paper.For the mechanical structure part of thedesign mainly studied the human body size data,and combined with the theoreticalknowledge of ergonomics to carry out a more humanized design of each structure of thewheelchair.The hardware system and software system constitute the whole multi-functionintelligent wheelchair control system.The control system of the intelligent wheelchair iscontrolled by STM32 microcontroller,and the hardware is distributed reasonably with theserial port distribution function.Together with the control program,the control system of theentire design is constituted,and the functional requirements of each part of the intelligentwheelchair are completed.Finally,the paper summarizes the main research content andelaborates the research development direction.Keywords:intelligent wheelchair;Ergonomics;Wheelchair comfort;Control system;Massage system.2
