西瓜品质无损检测技术研究进展

Research Progress of Watermelon Nondestructive Examinations

西瓜品质无损检测方法主要有声学特性法、振动频谱法、介电常数法、可见/红外光谱技术法和核磁共振法等,然而应用于市场的检测装置还未面世。根据现有的检测方法,提出应用声音特性,采用LABVIEW采集与处理技术拟研制台式西瓜无损检测系统,应用DSP处理技术拟研制便携式西瓜无损检测装置。

There are many detection technologies for watermelon quality nondestructive examination,which includes acoustic property,vibration frequency spectrum,electric inductivity,visible and near-infrared spectroscopy,nuclear magnetic resonance,et al,but there is not a detection device used in market.According to the present detection methods,proposes that by sound detecting methods,uses LABVIEW collecting technology to develop desk-top watermelon nondestructive detection devices and DSP processing technology to develop the portable type.
