Technical Field

The utility model relates to an automatic frost prevention of crops freezes technical field, especially relates to a crops intelligence frost prevention system based on NB-IoT technique.

Background

Frost appears in autumn, winter and spring. Frost means that the air temperature drops suddenly and the ground surface temperature drops to below 0 ℃, so that crops are damaged and even die. The first frost in autumn every year is called initial frost, the last frost in spring next year is called final frost, and the influence of the initial and final frost on crops is large. The temperature after the plant enters the autumn is obviously reduced along with the frequent invasion of cold air, especially at the sunny night or early morning, the radiation heat dissipation is increased, the temperature of the ground and the surface of the plant is rapidly reduced, and when the temperature of the plant is reduced to be below 0 ℃, cells in the plant can be dehydrated and frozen to be damaged by frost. The first frost in autumn is usually called incipient frost, because incipient frost always damages crops in quiet and silent periods, so that crops are called "autumn killers". In order to ensure that crops can effectively prevent and control frost, the frost occurrence rule is determined, the environmental parameter change before frost occurrence is collected, and then the influence of frost on the crops can be effectively avoided through active and active external intervention.

3. And an information transmission means suitable for the growing environment of crops is lacked. Crops growth environment span is big, and wireless signal covers relatively poorly, even if set up all kinds of sensors, intelligent control ware also difficult and remote monitoring terminal realize that remote wireless communication is comparatively difficult, perhaps communication quality is not good enough. And the cost of laying the line network is high, and the maintenance difficulty is large.
