摘要
介绍了利用仓储害虫的吃食和爬行声进行仓储害虫检测可行性设计方案 .其思路是对粮库和中草药仓库采集的声信号进行傅里叶频谱分析 ,根据声信号的强度确定害虫种群的数量 ;
According to the sounds of pests crawling and eating,testing pest of stores by information technology is a kind of new technology.This paper presents its design project to sounds of pest crawling.It determines the number of pest through fourier analysis,the kind of pest by basic frequency.
