Intelligent greenhouse irrigation device capable of automatically adjusting water spraying mode based on tomato growth states

Abstract

The invention relates to an intelligent greenhouse irrigation device capable of automatically adjusting a water spraying mode based on tomato growth states. The device structurally comprises a camera,an upper computer, a lower computer and a spray irrigation structure, and the camera is mounted in a greenhouse and used for shooting tomato plant photographs and transmitting the photographs to theupper computer. After the tomato plant photographs transmitted by the camera are received by the upper computer, the photographs are analyzed by the aid of a model based on a deep learning algorithm,a tomato growth cycle model is identified, and operations corresponding to the irrigation device in tomato growth cycles are transmitted to the lower computer. After operation information transmittedby the lower computer is received by the lower computer, adjustment of the irrigation device is controlled, and irrigation is implemented. The device has the advantages that crop growth is protected,the quality of agricultural products is improved, human cost is saved, and waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the field of irrigation equipment for agricultural greenhouses, and in particular relates to an intelligent irrigation device for greenhouses that automatically adjusts the water spray mode based on the growth state of tomatoes. Background technique [0002] Tomatoes have well-developed roots, strong water absorption capacity, and strong evaporation of water from the leaves. They are drought-tolerant crops, which are drought-tolerant and require a lot of water. The growth process of tomatoes has certain stages and periodicity, which can be roughly divided into germination period, seedling period, flowering period and fruiting period. Each stage of tomato growth has different requirements for water volume and droplet diameter. The germination and seedling stage grows fast, and the soil should not be too wet. The amount of irrigation and the droplet diameter should be controlled. Frequent watering is required during the flowerin...

AI Technical Summary

Problems solved by technology

The spraying area of ​​the rotary sprinkler is relatively wide and the use effect is good, but the structure is relatively complicated and the cost is too high. Although the structure of the diffuse sprinkler is simple and the cost is low, the spraying area is relatively small and the irrigation effect is not good. The same effect of the sprinkler head needs to be purchased with more scattered sprinkler heads, and the spraying distance is fixed at the same time, which cannot be watered for long-distance and middle-distance plants.
