Abstract

Regarding a granary, the invention relates to a device for measuring and monitoring the temperature and the humidity of the granary. The device can achieve the automatic ventilation and adjustment functions. The device comprises a core control module, a ventilation module, a temperature and humidity data transmitting module, a data receiving module and a data terminal. The core control module is installed in the granary, the ventilation module is installed on a ceiling of the granary, the temperature and humidity data transmitting module is installed outside the granary, and the data receiving module and the data terminal are installed in a monitoring chamber. The core control module is placed in the granary, and a master controller of the core control module is connected with a temperature and humidity sensor, a temperature sensor and the ventilation module. Data of the temperature and the humidity of the granary are collected and extracted, the state of the interior of the granary is judged through an intelligent algorithm, the temperature and the humidity of the granary are adjusted, the inspected result is sent to an upper computer, and therefore an inspector can monitor the granary in real time.

Description

technical field [0001] The invention relates to a granary temperature and humidity measurement and monitoring device capable of realizing the function of automatic ventilation adjustment for a granary. Background technique [0002] Grain is a country's strategic resource, and grain storage has always been a national key issue. Real-time automatic monitoring and adjustment of temperature and humidity in granaries is an important part of the field of agricultural automation, and its research and application have made great progress in recent years. However, the existing granary measurement and control system is mainly a combination of wired and manual methods. The wiring is complicated, the investment is large, and the workload is heavy. It takes a lot of manpower and financial resources to detect the grain temperature and collect data one by one. The accuracy is poor and the temperature of the granary cannot be obtained in real time. humidity data. Therefore, it has become ...
