Intelligent grain drying production line

Abstract

The invention discloses an intelligent grain drying production line. The intelligent grain drying production line comprises a grain drying machine, a hot-air furnace and a control system, wherein the control system comprises a single chip processing module, a grain water content sensor, a grain temperature sensor, a hot-air pressure sensor, a hot-air temperature sensor, a three-phase SPWM wave output module and an alarm module are connected to the single chip processing module; the three-phase SPWM wave output module is connected with the grain drying machine and the hot-air furnace respectively; and A/D converters are connected among the grain water content sensor, the grain temperature sensor, the hot-air pressure sensor, the hot-air temperature sensor and the single chip processing module. An automatic control system for grain drying, which is disclosed by the invention, is capable of realizing dual control on the grain drying machine and the hot-air furnace, intelligently and automatically adjusting the working states of the drying machine and the hot-air furnace according to a water content and a temperature in grains, and further increasing the intelligence degree of grain drying operation.

Description

technical field [0001] The invention relates to the technical field of intelligent production, in particular to an intelligent grain drying production line. Background technique [0002] my country is the largest grain producer and consumer country in the world, but at present most of the grain drying still relies on the traditional natural drying method. Mildew, etc., have caused huge losses, so the use of grain dryers has become very necessary, but the existing grain dryers are mainly manual operations, with a low degree of automation, resulting in high energy consumption and low efficiency of the dryers. And the operation is inconvenient. [0003] Chinese patent CN 102679711 A proposes an automatic control device for a grain dryer, which can automatically adjust the operating frequency of the dryer according to the moisture and temperature in the grain, realize intelligent control, and improve the degree of automation of the grain dryer. However, the technical solution ac...
