摘要
基于昆虫声音的储粮害虫检测是以生物学者的基础研究为基石,以数字信号处理理论和技术为方法,将声信号变成电讯号,去除噪声提取实用的信号,进行信号放大处理后,根据音程的百分比和音程数量的多少可以分辨出储粮害虫的种类和数量。
To check - up stored grain injurious insects based on insect sound is conducted following the groundwork of biologists and by using digital signal processing theory and technology. The acoustic signal is changed into electronic vibration, the yawp is wiped off, and the practical signal is obtained. The species and number of the stored grain injurious insects can be confirmed according to the magnified signal.
