Abstract

Study on the movement posture measurement system based on traction parallel

Author(s): Lirong Zhang

The key of traction parallel is to make the posture get a more accurate measurement process during the human body movement by carrying out the cable measurement between the moving platform and the static platform, so as to provide a strong foundation for the posture accuracy during the human body movement. In the research and exploration of this area, first, it carries out an in-depth exploration for the layout and basic unit of the measurement system. Through the establishment of appropriate mathematical model, it makes the human movement measurement process become a relatively simple process from a complex process. In this process, this study researches from the aspects of basic configuration of the pose measurement unit and the definition the measurement unit movement parameter to ensure the basic structural of the measurement unit maintain highly unambiguous and confirm the movement parameter of the measurement unit effectively. After that, it explores the relationship between the three point layout of the moving platform and the segment parameters of human body specifically. The main aspects are the explorations to the selection of motor control mode, the working principle of DC motor and location working mode to make the system work process maintain a high degree of accuracy and lay a solid foundation for the construction of the system and the accurately and efficiently operation. Finally, this study discusses the position measuring workspace derivation of the measurement system and the analysis of error sources of the measurement system to improve the effectiveness of the system construction. This is the main idea of the research process, which fully reflects the specific purpose and content of the study.
