Automatic field irrigation and drainage system

Abstract

The invention provides an automatic field irrigation and drainage system which comprises a water depth detector, a humidity detector, a water conveying pipe, a water absorbing mechanism, a plurality of spray heads, a drainage valve, a camera device and a controller. The water depth detector is arranged in a field and used for detecting the depth of a water layer. The humidity detector is arranged in the field and used for detecting the soil humidity. The spray heads are scattered in the field and connected with the water conveying pipe to be used for spraying a water source conveyed by the water conveying pipe into the field. The water absorbing mechanism is arranged on the water conveying pipe and used for controlling water conveying work. The drainage valve is arranged at the water outlet end of a field ditch and used for controlling drainage of the field ditch. The camera device is arranged in the field and used for taking plant growth pictures. The controller is connected with the water depth detector, the humidity detector, the water absorbing mechanism, the drainage valve and the camera device. The automatic field irrigation and drainage system automatically adjusts the field water amount, and is high in real-time performance, high in automation degree and low in labor cost.

Description

technical field [0001] The invention relates to the technical field of irrigation and drainage, in particular to a field automatic irrigation and drainage system. Background technique [0002] At present, the shortage of water resources in my country is becoming more and more prominent. Among them, agricultural water accounts for more than 70% of the total water resources, and crop planting water accounts for more than 90%. The tense trend is not sustainable. [0003] In recent years, the non-engineering water-saving and yield-increasing advantages of crop water-saving irrigation such as "shallow, wet, sun-dried, frequent irrigation, and less irrigation" have been fully affirmed and popularized and applied to a certain extent. However, human factors Extensive management and waste are widespread, and the contradiction between supply and demand of crop planting water is still difficult to alleviate. The reason is that scientific control irrigation technologies such as frequen...

[0003] In recent years, the non-engineering water-saving and yield-increasing advantages of crop water-saving irrigation such as "shallow, wet, sun-dried, frequent irrigation, and less irrigation" have been fully affirmed and popularized and applied to a certain extent. However, human factors Extensive management and waste are widespread, and the contradiction between supply and demand of crop planting water is still difficult to alleviate

The reason is that scientific control irrigation technologies such as frequent irrigation and less irrigation require too much labor time and labor costs, and there is no corresponding intelligent control technology and technology that can save time, labor, labor, and low cost. The support of instruments and equipment is one of the important factors
