Abstract

The invention discloses a high-efficiency online drying system for grain moisture, and relates to the technical field of drying equipment. The high-efficiency online drying system for the grain moisture comprises a power supply control unit (110), a touch screen display control unit (120), a PLC (Programmable Logic Controller) data control unit (130) and a grain moisture detecting unit (140), wherein the PLC data control unit (130) is respectively interconnected with the touch screen display control unit (120), the power supply control unit (110) and the grain moisture detecting unit (140). On the basis of the resistance moisture detecting method, the high-efficiency online drying system for the grain moisture applies the nonlinear processing capacity of an RBF (Radial Basis Function) neutral network algorithm to fuse the measured data, and can automatically implement various corrections and error compensations for the measured value, so that the reliability and measurement precision of the grain moisture detecting system are improved; meanwhile, a real-time control system based on a PLC and matched with grain drying equipment is independently researched and developed to realize the functions of automatic control, online display, fault alarming and grain moisture detection in the grain drying process.

Description

Technical field: [0001] The invention relates to the technical field of grain drying equipment, in particular to a high-efficiency grain moisture online drying system. Background technique: [0002] Grain moisture detection is of great significance to the purchase, transportation, storage, and processing trade of grain. Excessive moisture wastes transportation capacity and storage capacity, and promotes vigorous food life activities, which can easily cause food fever, mildew, insects and other biochemical changes. The low moisture content of grain reduces the weight of grain and affects grain quality. Therefore, moisture has always been an important quality indicator of grain, and accurate detection of grain moisture content has become an important issue. [0003] Grain moisture detection technology is generally divided into direct method and indirect method. The direct method is to directly remove the moisture in the grain through drying or chemical methods, and detect the abso...
