多因素影响下动物体的直流触电电流响应特性分析
Analysis of DC electric shock current response characteristics in animals under multiple influence factors
摘要
Abstract
To address the unclear characteristics of current response under DC electric shock,this paper analyzes the time-domain response characteristics,including current amplitude,peak rise time,and sliding slope of DC electric shock current in animals under multiple factors.A time-frequency response characteristic analysis method based on variational mode decomposition and singular value decomposition(VMD-SVD)is also proposed.First,the DC electric shock current amplitude,sliding slope,and peak rise time in live pigs are analyzed under various conditions,including different electric shock methods,electric shock voltages,skin surface dryness and humidity,current paths,and animal body mass.This reveals the relationship between the electric shock current response characteristics and these multiple factors.At the same time,the influence of various factors on the DC electric shock current characteristics of live pigs is quantitatively analyzed,revealing the quantitative relationship between animal body mass,shock voltage,and current amplitude.Finally,the VMD-SVD method is used to analyze the time-frequency response characteristics of DC electric shock current in living pigs before and after electric shock under multiple factors.The results show significant differences in the maximum singular value and singular entropy characteristics before and after electric shock,although under the influence of multiple factors,these differences remain within 10%.关键词
