Design and Implementation of Data Acquisition Subsystem Based on RF Signal Human Motion Recognition

Abstract

This paper designs and realizes the data acquisition subsystem based on RF signal human motion recognition to make the data acquisition in a unified format. This data acquisition system collects data of different human motions, getting RSS data for human motion recognition. Due to the coarse-grained nature of RSS data itself, the data acquisition system adds the data preprocessing function to refine the motion data characteristics. This paper designs the data preprocessing algorithms, including the upsampling algorithm, the energy information converting algorithm, the human motion duration extracting algorithm. The data acquisition system is divided into data acquisition module, data upsampling module, data energy information converting module and human motion duration extracting module, realizing each module in the realization of the system, and specifying the data collection format in the data acquisition module. The main function of the data acquisition system is to collect the RSS data of different human motions, preprocessing the collected data, refining the motion characteristics and generating the data sets of different motions.
