Design And Application Study Of Wireless Information Acquisition System For Human Motion Acceleration Information

The acceleration information acquisition is the premise for the study of human motion. Firstly, the lecture studies the research status of acceleration information acquisition of human motion. Then, based on the research status of the world and the empty of inland, and the request of our lab, we propose the study of'Design and Application Study of Wireless Information Acquisition System for Human Motion Acceleration Information'. The article which decides to study the human motion acceleration drives the development of this study and has important foundation significance.The main research objectives of this paper are: providing a solution for wireless human motion acceleration information acquisition system, developing a device of human motion acceleration information acquisition system, and then conducting a preliminary study and exploration of the acceleration information acquisition system in related fields.Based on the study of acceleration information acquisition technology, combined with the practical application of the requirements, this paper designs and develops an information acquisition system based on wireless communication technology and portable technology which can not only gain the human motion acceleration in one place of the body, but can also gain the human motion acceleration in 12 places of the body at one time. Then, develops applied research in human waist and leg motion acceleration information acquisition. The result proves the stability, reliability and practicality of the system.This paper firstly analyzes the collectivity of the system, and proposes the task of the system design. Then, analyzes the acceleration information acquisition technology, and adopt acceleration IC to gain the human motion acceleration according to the applied circumstance. Next, proposes a kind of system architecture that a control system works with a number of acquisition subsystems, and analyzes the requirements of the entire acquisition system. At last, proposes a novel distributed wireless information acquisition system for human motion acceleration gain.This paper analyzes the design process of the acceleration information acquisition system. Firstly, put forwards the general principles of the hardware system design, optimizes the information gain subsystem hardware design requirements, and then proposes one system design blue print which has not memory module. Finally, discuss the control system hardware design process in detail.The thesis detailed analysis and discusses the process of embedded software and PC application software of the human motion acceleration information acquisition system. Firstly, proposes the general principles of software design, then basing on the low-power requirements of the system, optimizes the design of the system workflow. At last, designs and implements the embedded software and PC applications.Develops applied research of the human motion acceleration information acquisition system. First of all, let foot acceleration information acquisition as an example, the paper focusing on three-dimensional acceleration of the foot and carry out applied research. Then, basing on the three-dimensional acceleration information of the foot, this paper carried out analysis and research of the gait cycle. At last, this paper carried out analysis and research of this acceleration acquisition system in waist and leg acceleration gain. Application studies of the above have demonstrated the stability of the system, as well as practical significance for system design.The achievement of the wireless acquisition system for human motion acceleration information provides an important experimental platform for the human motion acceleration acquisition and for the applied research information based on the acceleration information which has an important significance.
