Aiming at the problem of lacking effect moisture detection method for large grain pile,it proposes a new method using electromagnetic wave detection to overcome the shortcomings of traditional methods such as poor precision,complexity and so on.Based on the principles of reflection and refraction of electromagnetic wave on different media interface,it obtains the dielectric constant of grain surface,according to the law of reflection and refraction,it uses the surface dielectric constant to infer the distri...
