Automatic control system of intelligent low-temperature grain storage and control method thereof

Abstract

The invention relates to an automatic control system of intelligent low-temperature grain storage and a control method thereof. The automatic control system is provided with a plurality of three-dimensional vent pipes which are vertically arranged in storage space in a grain store; a three-dimensional branch vent is divided into multiple groups of first branches and second branches for which air blast and indraft are exchanged, wherein the first branch is connected with the air outlet of a circulating fan respectively through a first divided manifold and a first header pipe, and the second branch is connected with the air inlet of the circulating fan respectively by a second divided manifold and a second header pipe; a first branch pipe and a second branch pipe which carry out wind direction commutation control to the first branch and the second branch by an air valve are arranged between a blast main and an air suction header pipe; and the first branch, the second branch, the first divided manifold, the second divided manifold, the first header pipe and the second header pipe are all provided with a motor-driven air valve connected with the control device. The system and the method of the invention assure grain storage quality, save fund and energy, obtain the purpose of environmentally-friendly storage, can assure the safety and health of prevention personnel, reduce larbor intensity and have simple operation.

Description

technical field [0001] The invention relates to a low-temperature grain storage technology, in particular to an intelligent low-temperature grain storage automatic control system and a control method thereof. Background technique [0002] With the economic development of the society, the continuous improvement of the level of science and technology and people's living standards, people's demand for high-quality, high-nutrition green food is increasing day by day. The direction of world food storage. [0003] Low-temperature grain storage is a reliable guarantee of "low consumption, low cost, low pollution, high quality, high nutrition, and high benefit" in the modern grain storage industry. After my country's accession to the WTO, the grain storage industry will be integrated into the globalized environment to a greater extent, the quality of grain storage will be improved, the cost of grain storage will be reduced, and the safety and freshness of grain storage will be guar...

AI Technical Summary

Problems solved by technology

During the conventional storage of grain, insects and mildew occur from time to time. With the extension of time and the increase of temperature, the aging speed of grain is accelerated at room temperature, and its nutritional quality is seriously lost.

[0005] Since the reform and opening up, the grain industry has often encountered the following problems in the process of purchasing and storing: In the process of purchasing grain, it is impossible to completely guarantee the control of the safe moisture index. If the purchase is based on safe moisture, it is difficult to find enough grain sources

At present, there is no report on the grain storage system that can meet the above requirements
