Problems solved by technology

The outside temperature at night and in the morning is low, so it is suitable for forced ventilation. The management personnel need to turn on the fan, and when the outside temperature rises, they need to turn off the fan. The temperature and humidity in the warehouse cannot be effectively regulated, especially the temperature and humidit

Embodiment Construction

[0018] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] Such as figure 1 As shown, an automatic control device for forced ventilation during potato storage includes a temperature sensor, a central processing module, a display module, a clock module, a fan control module and a fan, and the temperature sensor transmits the collected temperature values ​​to the central processing module. The processing module performs operations on the collected temperature values, and transmits the processing results to the fan control module through instructions. The fan control module controls the fan switch according to the received instructions. The display module displays the temperature values ​​measured by the temperature sens...

Abstract

The invention discloses an automatic controller used for forced ventilation in the storage period of potatoes. The automatic controller comprises a temperature sensor, a central processing module, a display module, a clock module, a fan control module and a fan. An output end of the temperature sensor is electrically connected to an input end of the central processing module, an output end of the central processing module is connected to an input end of the fan control module, the fan control module is connected with the fan, the display module is electrically connected with the central processing module, and the clock module is electrically connected to the central processing module. Therefore, the fan can be intelligently controlled according to temperature changes of storage environment, ventilation and temperature reducing effects inside potato piles are increased, storage time of potatoes is prolonged, storage loss of the potatoes is reduced, and labor intensity of managers is also reduced.

Description

technical field [0001] The invention relates to the field of forced ventilation storage facilities for agricultural products, in particular to an automatic control device for forced ventilation during potato storage. Background technique [0002] Potato is a fresh agricultural product that requires a long storage period. In order to reduce storage loss, maintain edible quality, and extend storage period, potatoes need to be properly ventilated during storage. Scientific and reasonable ventilation can not only adjust the temperature and humidity inside the storage and carbon dioxide content, but also to avoid condensation on the surface of potato skins. At present, some potato storages in the northern part of my country are equipped with forced ventilation systems, and the switch of the fan is mainly controlled by the switch manually. The outside temperature is low at night and in the morning, which is suitable for forced ventilation. The management personnel need to turn on...
