Granary temperature-humidity control method and system

Abstract

The invention discloses a granary temperature-humidity control method. The method comprises the steps of a starting step,preparation step,regulating step and status report step in sequence,wherein thestarting step is used for electrifying and starting equipment and completing the deployment of a control system,the preparation step is used for determining whether or not the power supply situationis suitable for executing the regulating step,the regulating step is used for regulating the temperature and humidity in a granary,and the status report step is used for reporting running status information of the system outward; the regulating step comprises that a threshold is set; the temperature and humidity in the granary are acquired; it is judged whether or not the temperature and / or humidity exceed the threshold; if yes,the temperature and / or humidity are regulated; and if no,an adjusting device is in a shutdown state. The invention further discloses a granary temperature-humidity control system applied to the control method,temperature-humidity data inside and outside the granary is monitored comprehensively,and the running status of the adjusting device is automatically controlled,thereby achieving the automatic regulation of the grain storage.

Description

technical field [0001] The invention relates to the field of grain storage, in particular to a method and system for controlling the temperature and humidity of a granary. Background technique [0002] In recent years, my country's granary has developed relatively rapidly. The original brick-wood structure and bamboo-wood structure have developed into today's tall square silos, vertical silos, and shallow round silos. The storage capacity has also been significantly improved. At present, although the grain storage warehouses in most areas of our country have basically completed the modernization, they are equipped with ventilation and adjustment equipment such as air conditioners, axial fans, and ventilation windows. The air temperature is adjusted so that the grain in the entire warehouse can be in a low temperature and low humidity environment suitable for storage. [0003] The problem is that the adjustment of the temperature and humidity in the warehouse needs to judge ...

AI Technical Summary

Problems solved by technology

[0003] The problem is that the adjustment of the temperature and humidity in the warehouse needs to judge the temperature and humidity through the operator's body feeling and manually control the start and stop of the temperature and humidity adjustment device in the warehouse. Problems such as untimely adjustment or inappropriate setting of adjustment parameters lead to rapid changes in grain quality and the quality of grain storage cannot be guaranteed
