Automatic control device and automatic control method for grain storage bin

Abstract

The invention relates to an automatic control device for a grain silo. A cone bottom is a convex cone bottom. The automatic control device comprises a nitrogen adjusting module, a circulating fumigation / air ventilation integrated module, a control module and a detection module, wherein the nitrogen adjusting module, the circulating fumigation / air ventilation integrated module and the detection module are separately connected with the control module; the detection module comprises detection sensors for detecting temperature, humidity and gas content; and the detection sensors are separately connected with a logic comparator (15) through electrical signals, the logic comparator (15) is connected with an assessment model (16) which is connected with a computer (17), the computer (17) is connected with an executor (22), and the logic comparator (16) performs execution motion according to detection values of the detection sensors and the assessment model. The automatic control device for the grain silo performs comprehensive judgment according to the detection data of environment climate conditions, grain situation detecting results, the temperature, the humidity, oxygen concentration and the like, and selects to perform execution in one of three using modes, so that the automatic control of the grain silo is achieved.

Description

technical field [0001] The invention relates to the technical field of grain storage bins, in particular to an automatic control device for grain storage bins and an automatic control method thereof. Background technique [0002] Grain storage technology has always been valued by the country's war preparation materials. The grain is vulnerable to various pests during the storage process. At the same time, due to the long storage period, the temperature and humidity of the grain pile change with the seasonal changes of the outside world, causing heat and mildew of the grain, resulting in grain quality changes. [0003] At present, when inspecting the grain situation of the granary in our country, it is necessary to manually enter the granary for regular inspection. More than three operators must enter the warehouse together, and each time they enter the warehouse for no more than half an hour in a row. In the low-oxygen warehouse environment, they need to wear air respirator...

Problems solved by technology

However, long-term low-temperature storage makes the humidity adjustment function of the grain storage bin worse, and it is necessary to regularly use mechanical ventilation to remove high-humidity areas to obtain a drier grain storage pile. However, there is no environmental climate condition or grain situation in the grain storage bin in the prior art. To determine the operating mode of the storage bin
