針對(duì)現(xiàn)有的太陽(yáng)能殺蟲(chóng)燈害蟲(chóng)計(jì)數(shù)方法不精確的問(wèn)題,設(shè)計(jì)了一種基于電壓和聲音融合的太陽(yáng)能殺蟲(chóng)燈害蟲(chóng)計(jì)數(shù)方法。為解決對(duì)單只害蟲(chóng)重復(fù)計(jì)數(shù)的問(wèn)題,,對(duì)聲音模擬數(shù)據(jù)進(jìn)行處理,,提出了一種基于MFCC特征的相鄰脈沖間隔計(jì)數(shù)的方法,有效的減少了重復(fù)計(jì)數(shù),。使用機(jī)器學(xué)習(xí)對(duì)電壓和聲音兩種計(jì)數(shù)方法做決策,計(jì)數(shù)最后的殺蟲(chóng)數(shù)量?;谠O(shè)計(jì)的方法,在農(nóng)田環(huán)境下進(jìn)行驗(yàn)證,,其準(zhǔn)確率為93.28%,。
