Problems solved by technology

At present, the grain moisture detection in the grain pile has not yet realized rapid detection and automatic control. The grain moisture detection of large storage grain piles such as shallow round warehouses and flat warehouses usually uses sampling-type detection instruments, such as infrared and halogen heating weighing heavy-duty instruments, which cannot achieve continuous On-line detection and unattended operation, other online instruments based on capacitance and microwave detection principles have complex structures and high costs, and cannot be densely arranged in grain piles

Abstract

The invention provides an online grain moisture content detection system and method based on temperature and humidity inversion. The system comprises a core micro-controller and temperature and humidity detection units, wherein the temperature and humidity detection units comprise temperature detection units and humidity detection units; the core micro-controller comprises a temperature and humidity data acquisition and processing unit, a timer unit, a grain balance moisture content calculation unit, a historical temperature and humidity data and historical grain balance moisture content data storage unit, a grain moisture content compensation calculation unit, a historical grain moisture content data storage unit and an upper computer communication interface unit. The system can be automatically timed to detect the grain moisture content in each position in a grain mass without manual sampling detection, is high in accuracy, can be used for simultaneously detecting a plurality of sites, and fills up the current blank of online intelligent grain moisture detection in China.

Description

Technical field [0001] The invention relates to the technical field of development of intelligent monitoring equipment for grain storage, in particular to an online grain moisture detection system and method based on temperature and humidity inversion. Background technique [0002] Grain moisture detection is of great significance to the purchase, transportation, storage, and processing trade of grain. Excessive water wastes transportation capacity and storage capacity and promotes vigorous life activities of grains and oils, which can easily cause grain fever, mildew, insects and other biochemical changes. In our country, due to imperfect moisture detection technology, tens of billions of catties of grains are moldy and deteriorated during transportation and storage due to high moisture content each year, causing huge losses. The low moisture content of grain reduces grain weight and affects grain quality. Therefore, moisture has always been an important quality indicator of g...
