Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Before explaining the on-line detection device and method for stored grain moisture content based on ground penetrating radar technology provided by the present invention, the principle of the present invention will be described first. As we all know, the dielectric constant of grain directly reflects the level of its moisture content. Therefore, the present invention can detect the amount of moisture (that is, the moisture content) contained in the grain related to the dielectric constant inside the granary by comparing the difference in the return time of the electromagnetic wave of the grain with different moisture content, and generate a detection report for the user to browse.

[0024] see figure 1 , figure 1 It is a system block diagram of the online detection device for the moisture content of stored grains based on the ground pe...

Abstract

The invention discloses an apparatus for the online detection of the content of water in stored grains based on a ground penetrating radar technology, and a method thereof. The apparatus comprises a radar module, a drive module and a monitoring end. The drive module receives a control signal from the monitoring end and drives the radar module according to the control signal to make the radar module move in a plane of a detection zone; when the radar module is in the detection zone, the radar module sends a pulse signal to the detection zone; the radar module receives a target echo reflected from the detection zone, calculates according to a processed target echo to obtain a corresponding dielectric constant, and transmits the dielectric constant to the monitoring end; and the monitoring end corresponds the relationship between the received dielectric constant and a water content to generate a detection report. The apparatus and the method improve the technical effect of the management efficiency of the storage and transportation environment of the grains.

Description

technical field [0001] The invention relates to the field of moisture detection of stored grains, in particular to an on-line detection device and method for the moisture content of stored grains based on ground penetrating radar technology. Background technique [0002] The moisture content of stored grain is a key indicator of food security, which directly affects the process of grain storage, processing, and trade. If you do not know the relevant temperature and moisture information of stored grain in time, it will inevitably affect the storage cycle of grain, leading to premature mold, deterioration, and rot of grain. Therefore, we must always pay attention to the moisture content of grain. In particular, the quality of different batches of grains put into the warehouse is different. The grains that have been put into the warehouse in advance are piled up at the bottom of the granary. After a period of storage, the temperature and humidity will change greatly. important...
