Description

Technical Field

[0001] The present invention relates to the technical field of crop irrigation, and in particular to a crop water-saving irrigation device based on the agricultural Internet of Things. Background Art

[0002] Global water resources are becoming increasingly scarce. In many areas, agricultural water consumption accounts for a large proportion of total water consumption, which makes water-saving irrigation in the agricultural field an inevitable demand. The growth of crops requires an appropriate and timely supply of water, and the water requirements of different crops at different growth stages vary greatly. Traditional irrigation methods, such as flooding, not only waste water resources, but may also cause problems such as soil waterlogging and nutrient loss due to uneven irrigation, affecting the growth and yield of crops. Therefore, an irrigation device that can accurately supply water is needed to meet the growth needs of crops and save water resources.

[0003] The Internet of Things is a technology system that closely connects the physical world with the information world through sensing devices, network transmission and application platforms. By collecting a large amount of soil moisture, meteorological and other data, a crop water demand model can be established. Cloud computing platforms can store and process these massive data and generate accurate irrigation decisions based on different crops, different growth stages and weather changes.

[0004] The existing device mainly uses spray irrigation to irrigate crops in a water-saving manner. The existing technology is similar to an agricultural water-saving irrigation system and a water-saving irrigation method thereof. The structure with the publication number CN109618889A includes an irrigation water storage tank, a filter device and an irrigation water pipe; the water outlet of the irrigation water storage tank is connected to the water inlet of the filter device; the irrigation water pipe includes a main water pipe, an above-ground irrigation water branch pipe and an underground irrigation water branch pipe, and the water outlet of the filter device is connected to the water inlet of the main water pipe; the water outlet of the main water pipe is connected to the water inlet of the above-ground irrigation water branch pipe and the underground irrigation water branch pipe respectively; the above-ground irrigation water branch pipe is provided with a first spray structure, and the underground irrigation water branch pipe is provided with a second spray structure; the irrigation water in the irrigation water storage tank is dispersed to the agricultural soil through the first spray structure and the second spray structure. The invention can achieve the purpose of maximum water saving while reasonably irrigating according to the water shortage of crops in the agricultural soil at various times by setting up two methods, namely, above-ground sprinkler irrigation and underground drip irrigation. However, there are still areas that can be optimized in the device.

[0005] The existing devices mainly irrigate crops through sprinklers in a fixed state, which makes it difficult for some devices to rotate and spray the surrounding crops, resulting in blockage of some sprinkler ports and difficulty in uniformly irrigating the crops. Secondly, some devices mainly irrigate crops in a circular range through sprinklers, which makes some devices have more repeated irrigation areas, resulting in a large waste of water resources. Finally, some devices are difficult to control the irrigation area by lifting and adjusting the sprinkler head, resulting in some devices can only irrigate crops in fixed areas, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a crop water-saving irrigation device based on agricultural Internet of Things is proposed. Summary of the invention
