Intelligent ventilation system of grain depot

Abstract

The invention discloses an intelligent ventilation system of a grain depot, which comprises a ventilation window mechanism, a control mechanism and a detection mechanism, wherein the three mechanisms are connected with one another by wires; the ventilation window mechanism comprises a ventilation window fixing sash; the internal surfaces of the bottom part and the two sides of the ventilation window fixing sash are hinged with ventilation window moving windows; the end parts of two vertical segments of each ventilation window moving window are both hinged with drive connecting rods through draw bars; all the drive connecting rods are welded on the same drive rotating shaft; the other end of the drive rotating shaft is connected with a worm gear; the worm gear is connected with a drive motor; the drive motor is connected with the control mechanism; one end of the worm gear is connected with a position detector; a bearing support, the worm gear and the position detector are all arranged on a bottom plate; a PLC control system is arranged in the control mechanism; and a touch screen is arranged on the outer surface of the control mechanism. The intelligent ventilation system of the grain depot has the advantages of low work intensity, high efficiency, high degree of automation and high reliability.

Description

Technical field: [0001] The invention relates to a grain storage management system, which is a system capable of automatically realizing intelligent ventilation control of a grain depot. Background technique: [0002] As an important strategic material of the country, grain reserves have assumed important responsibilities in maintaining the grain market and social stability, protecting the interests of farmers, and ensuring national security. Our government has always regarded the management of grain reserves as an important economic task. Since 1998, the central treasury has continuously invested in treasury bonds in three batches to build a national grain reserve depot. At this stage, the conditions of my country's grain storage and storage facilities have been greatly improved. The grain reserves are basically stored in warehouses with good conditions, and the quantity and quality of the grain reserves are gradually guaranteed reliably. At present, in the warehouse dire...

Problems solved by technology

Although this method can meet certain ventilation requirements, it has many disadvantages. For example, a standard grain depot has as many as 20 ventilation openings. When opening and closing, the management personnel are labor-intensive and time-consuming, and it is difficult to make quick adjustments when the climate suddenly changes. Response, the judgment of external weather depends on manual implementation, and the reliability is low

At present, the traditional ventilation system methods are: (1) Indoor open type. After the grain storage in the warehouse is full, the ventilation window is opened by stepping on the grain, which brings the disadvantage of high strength. At the same time, it must be realized after t
