Intelligent grain storage ventilation system

Abstract

The invention discloses an intelligent grain storage ventilation system. The intelligent grain storage ventilation system comprises a grain situation detection unit, an intelligent ventilation unit and a grain situation monitoring and alarming unit. The grain situation detection unit comprises a grain pile temperature sensor arranged in a grain pile and a bin interior temperature and humidity sensor arranged above the bin interior grain pile, and the grain pile temperature and bin interior temperature and humidity data are output. The intelligent ventilation unit comprises a first server receiving the grain pile temperature and the bin interior temperature and humidity through a grain situation extension set, the first server compares the obtained real-time temperature and humidity of a small meteorological station outside a bin with the grain pile temperature and bin interior temperature and humidity, and ventilation equipment is controlled for running at different air volumes. Grain pile temperature alarming range threshold values of different grain varieties are further preset in the first server, and an alarm instruction is output if the value is not in the range of the alarming range threshold values. The grain situation monitoring and alarming unit comprises a display and an alarm device which are in communication with the first server. By means of the intelligent grain storage ventilation system, timely intelligent regulation and control can be conducted when the grain pile temperature and bin interior temperature and humidity deviate from control, the labor intensity of warehouse keepers is relieved, and the warehouse management cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of granary ventilation, and more specifically, the invention relates to an intelligent ventilation system for grain storage. Background technique [0002] When the grain is stored, if the temperature and humidity exceed the standard, heat and mildew will occur. The traditional method is to use testing equipment such as hygrometers, hair hygrometers, bimetallic measuring meters, and humidity test papers, through manual testing, to ventilate, dehumidify, and cool warehouses that do not meet the temperature and humidity requirements. The method of manual warehouse management, due to the large area and large scale of the grain warehouse, the large number of warehouses and the large capacity, manual inspection is difficult to ensure timely and accurate grasp of the changes in various monitoring indicators during the storage process, time-consuming and laborious, not smart enough, and cannot When the temperature ...
