Research on Muskmelon Maturity Detection Method Based on Acoustic Characteristics

In this article, acoustics characteristics is used for testing muskmelon interior quality, sends out the tone frequency through the rap method, established the acoustics characteristic and the quality relevance of fruits and vegetables. PRO/E 4.0 is used for modeling and simulation, automation computer-controlled stroking device is made, microphone is used for receiving the signal, LABVIEW software is used for collecting the acoustic signals, Origin8.1 is used for treatment the signals, including data smoothing, FFT analytical, data fitting, baseline peak value analysis and other methods, then modeling according to these analysis data. Testing the muskmelon by the acoustic characteristics, the research showed that there is remarkable linear relevance based on acoustics characteristics and muskmelon hardness.
