A Displacement Data Acquisition and Transmission System Based on a Wireless Body Domain Network

摘要

Wireless body domain network can monitor and collect the displacement data of the human body in real-time through the application of wireless sensor technology with the human body as the carrier, and upload the collected data to the displacement monitoring center for further analysis of the displacement data. In this paper, based on the wireless body domain network technology, to human body displacement data acquisition and transmission, through displacement data were collected for the human body gesture recognition and sports training, and so on to provide a series of technical support, the design of portable wearable human body displacement data acquisition unit, implements the multi-sensor wireless transmission, and application of Kalman filtering algorithm, the acquisition unit collected by the state variables and the quantity of observation data fusion and filtering, minimize noise interference, at the same time of six-axis gyro attitude algorithm by using three-axis attitude Angle of the body. To realize the real-time monitoring of human movement.
