Device for detecting activity of stored grain and method thereof

Abstract

The invention discloses a device for detecting activity of stored grain and a method thereof. The device comprises a micro air pump, a sensor array, a signal acquisition and conversion circuit and a computer, wherein the micro air pump is used for sucking the smell of the grain from a grain sample tank; the sensor array is connected with the micro air pump for outputting an electric signal which is generated after the interaction with the smell; the signal acquisition and conversion circuit is connected with the micro air pump and the sensor array for controlling the work of the micro air pump, acquiring the electric signal from the sensor array and converting the electric signal; and the computer is connected with the signal acquisition and conversion circuit for controlling the work of the signal acquisition and conversion circuit, extracting and analyzing the characteristic value of the data subjected to the processing of the signal acquisition and conversion circuit and judging the quality and/or activity level of the grain according to the analysis result. The device and the method can quickly judge the quality and/or activity level of the stored grain.

Description

technical field [0001] The invention relates to the technical field of automatic detection of agricultural products, in particular to a stored grain activity detection device and method applied in the field of agricultural product safety. Background technique [0002] my country is a populous country, and the food problem has always been a top priority. my country's annual grain output is about 500 million tons, of which the annual output of rice reaches 200 million tons, accounting for 35% of the world's annual output. Most of the grain needs to be circulated and stored in warehouses. However, in the process of domestic and foreign trade and circulation of grain, there is a lack of rapid quality testing methods. The existing grain quality testing methods of many grain purchasing departments mainly use human sensory touch, nose smell, mouth bite, and seeing to determine the quality of food. Various internal quality parameters, and there is a huge subjective error in quality...

Problems solved by technology

For a long time, incidents of stale grains have occurred many times in China. On July 15, 2000, Wuhan City auctioned 61,179 tons of stale grains and old grains through bidding transactions, and about 80% of them have lost their direct consumption. Unscrupulous traders take this opportunity to re-flow these grains into society and cause losses

Dealing with stale grain has become the top priority of my country's grain work. If there is no corresponding rapid detection method, the consequences will be disastrous
