Abstract

The invention provides a single-chip microcomputer based warehoused unhulled rice humidity on-line detection system, which consists of a humidity transmitter, an A / D converter, a single-chip microcomputer, a display part, an alarm indicator and a control motor.

Description

technical field [0001] The invention belongs to an on-line detection system for humidity of incoming rice based on a single-chip microcomputer. Background technique [0002] In large grain reserve depots, the purchased rice may become moldy due to excessive humidity. At present, before the rice enters the silo, it is mainly manually picked out for inspection, and it is difficult to control the humidity. Only when the humidity of the drawn grain bag is too high, which affects the appearance and smell of the grain, can it be detected. How to use testing instruments to detect the humidity of online transported grain before the grain enters the warehouse, and keep unqualified grain out of the warehouse door, so as to improve the quality of grain storage, is an important issue that has attracted much attention in grain storage. [0003] When the rice enters the warehouse, the soil workers usually open the bagged rice on the grain truck and put it on the conveyor belt, and then t...
