The invention discloses an online real-time monitoring system and method for grain moisture, which relates to the technical field of grain drying and includes a flat-plate capacitive sensor, a temperature sensor, a force sensor, a distance measuring sensor, a signal processing circuit, a data processing system and a human-computer interaction interface. The main purpose is to solve the problems of difficulty in online monitoring of grains in grain dryers and low monitoring accuracy. Among them, the flat capacitive sensor is installed in the grain flow channel behind the screw conveyor of the grain dryer, which is used to detect the current grain capacitance value and upload it to the data processing system through the signal processing circuit to calculate the current grain moisture value; use the temperature sensor to monitor the current grain value. Grain temperature, using the detection results of the force sensor and the ranging sensor to calculate the current grain density, and performing temperature and density compensation on the grain moisture detection value, which can realize accurate online real-time monitoring of grain moisture, and the present invention can be applied to grain drying machinery Grain moisture monitoring.
Description
technical field [0001] The invention relates to the field of grain drying, in particular to an on-line grain moisture monitoring system and method. Background technique [0002] Grain drying is an important part of agricultural product processing. It has the characteristics of nonlinearity and large lag, and manual control cannot achieve the desired effect. It is urgent to develop an intelligent grain drying mode. The basis of intelligent control of grain drying is real-time online and reliable monitoring of grain moisture in the drying process. Therefore, it is of great practical significance to study an on-line grain moisture monitoring system and method. [0003] Patent Application No. 201710400365.7 discloses a resistance-type grain moisture detector, and a precise adjustment system for the gap of the rolling wheel is designed to adapt to grain particles of different diameters, which improves the detection accuracy of grain moisture. Patent 201710400365.7 proposes a re...
