Abstract

The invention discloses a microwave on-line grain moisture content detection device and a method thereof. The device comprises a microcontroller, an interface circuit and a computer, which are sequentially connected with each other, and also comprises a high-frequency signal generator for generating a high-frequency signal, a high-frequency signal receiver for receiving the high-frequency signal which transmits through the grain, a signal regulation and detection circuit for detecting the amplitude value and phase difference of the high-frequency signal which is picked up by the high-frequency signal receiver and the high-frequency signal before transmitting through the grain and for transmitting the picked moisture content detection result to the computer through the microcontroller and the interface circuit, wherein the computer performs the density compensation for the moisture content detection result according to the density compensation algorithm. The auxiliary high-frequency signal amplitude value and phase difference detection technology and the density compensation algorithm are adopted to solve the density spacing influence of the grain particles.

Description

technical field [0001] The invention relates to the technical field of automatic detection of agricultural products, in particular to the microwave on-line grain moisture detection system, which is designed for the significant impact on the detection results due to the different grain varieties and particle shapes and sizes. The value and phase difference detection technology, as well as the density compensation algorithm, compensate and correct the microwave moisture detection to solve the influence of grain particle density. Background technique [0002] The moisture content of grain affects the physical, chemical and biological characteristics of grain, and is a key indicator of grain quality, directly affecting the process of grain purchase, transportation, storage, and processing trade. As a very high-frequency electromagnetic wave, microwave has strong penetrability. What it detects is not only the moisture on the surface of the grain, but also the moisture content ins...
