摘　　要：设计了一个皮肤电阻变异性在线监测系统。该系统分为数据采集、数据实时绘制、数据处理和时频分析四部分。结合Arduino NANO和ESP8266 Wi-Fi模块完成数据采集、传输。PC端接收到数据后用Python编程实现在线绘图、实时更新。MATLAB的小波分析工具箱提取皮肤电阻高频成分并进行时频域分析。最终实现了皮肤电阻变异性的在线监测。A wireless skin resistance variability monitoring system is designed in this paper.The system can be divided into four parts:data acquisition,real-time data display,data processing,and time-frequency analysis.Data acquisition and transmission use the Arduino NANO and ESP8266 Wi-Fi modules.The real-time drawing and updating on the PC are programmed by python.The MATLAB wavelet analysis toolbox was used for data processing and time-frequency domain analysis.This system provides reliable technical support for studying skin resistance variability.
