Embodiment Construction

[0031] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] figure 1 It shows a flow chart of an intelligent grain drying control method provided by an embodiment of the present invention, as shown in figure 1 shown, including the following steps:

[0033] Step S101: During the grain drying process, judge whether the grain needs to be dried in a delay mode according to the temperature signal, humidity signal and grain moisture value;

[0034] Step S102: When it is determined that the grain needs to enter the drying delay mode, a heating control signal is obtained according to the temperature signal and the humidity signal;

[0035] Step S103: Control the heating temperature and heating time of the grain a...

Abstract

The invention discloses an intelligent grain drying control method. According to the method, a temperature signal, a humidity signal and a grain moisture value are utilized for judging whether delayed-mode drying is required to be performed on grains or not and a heating control signal is obtained or other modes are started according to the judgment result, so that finally a target moisture value of the grains can be achieved. The intelligent grain drying control method can be used for achieving the intelligent management in a drying process, controlling the drying process by utilizes a fuzzy predictive control method, and adjusting drying time in a predictive way to adjust and control the grain drying time relatively accurately; the intelligent grain drying control method can be used for effectively overcoming a large delay link, shortening the adjusting time and eliminating the systematic quiet error.

Description

technical field [0001] The invention relates to the field of drying device control, in particular to the field of a control method for an intelligent drying device. Background technique [0002] my country is a large agricultural country, and it is also the largest food producing and consuming country in the world. At this stage, our country has solved the problem of food and clothing for the people. In 2011, my country's total grain output was 550 million tons, but according to the statistics of previous years, we know The loss of my country's grain in threshing, drying, storage and transportation after harvest has reached 15%, far exceeding the 5% standard stipulated by the Food and Agriculture Organization of the United Nations, and many farmers want to reduce field shattering when receiving goods The loss is harvested at the right time, but at this time the grain moisture is very large, if it is not dried in time, it will cause mildew and deterioration of the grain. Accord...
