Abstract

The invention belongs to the technical field of grain drying control and specifically relates to an intelligent control method for a grain drying tower based on neural network and fuzzy control. The hardware comprises a temperature / moisture sensor, a data collecting and treating module and an input and display module, wherein the temperature / moisture sensor is used for collecting temperature and moisture information; the data collecting and treating module is used for controlling the drying parameter according to the temperature and moisture information; the input and display module is used for performing man-machine interaction. The method comprises the following steps: 1) setting an initial value for the drying data according to a drying experience; 2) performing fuzzy control training on the system and drawing a control rule table; 3) sampling and correcting an error in the drying process. A drying tower is modeled according to the training data through the network; the error between a forecast moisture value after training and a moisture value calculated according to a model is small; the practical application requirement can be met; although a simple linear model is adopted, the training effect is excellent even if a higher order model is adopted.

Description

technical field [0001] The invention belongs to the technical field of grain drying control, in particular to an intelligent control method for a grain drying tower based on neural network and fuzzy control. Background technique [0002] There are more than 7,000 sets of large and medium-sized grain drying equipment in my country, and less than 5% of them are equipped with online moisture detection and control devices, which are basically controlled manually, which is likely to cause waste of grain due to excessive drying and energy waste caused by insufficient drying. The "Twelfth Five-Year Development Plan for the Grain Industry" issued by the National Development and Reform Commission and the State Grain Administration specifically puts forward the goal of improving the drying facilities. facilities, eliminate the drying capacity with backward technology, and keep the national drying capacity at more than 110 million tons, including more than 91 million tons in the northe...
