Intelligent irrigation system based on three-dimensional soil humidity chart

Abstract

The invention discloses an intelligent irrigation system based on a three-dimensional soil humidity chart. The system comprises humidity sensors arranged at different directions in soil, positioning nodes, an irrigation device and a monitoring terminal for building a humidity value distribution three-dimensional chart. The humidity sensors, the positioning nodes, the monitoring terminal and the irrigation device are sequentially connected; humidity values at the points can be obtained by arranging the humidity sensors at the few special points in soil, three-dimensional coordinates of the points are obtained through a positioning module, the humidity value distribution three-dimensional chart is built in the system, the three-dimensional humidity value in the soil is reflected, on the basis of intelligent irrigation, the soil humidity can be better controlled, the agricultural product quality is improved, the agricultural product yield is increased, the planting risk is lowered, economic benefits of farmers are greatly improved, and resource consumption and economic cost can be lowered by utilizing a limited number of humidity sensors.

Description

technical field [0001] The invention relates to the field of agricultural intelligent management systems, in particular to an intelligent watering system based on a three-dimensional soil moisture map. Background technique [0002] An important feature of modern agricultural production management is the use of sensors to detect the growth environment and growth of plants. Specifically, in terms of soil moisture detection, at present, multiple humidity sensors are usually placed in different places in the soil to obtain the humidity of multiple points. The management system judges whether to start the watering operation based on the humidity value at this point detected by the humidity sensor. [0003] The above scheme has certain limitations. Since the system measures the humidity values ​​of multiple single points in the soil, it cannot accurately express the humidity of the entire soil. The automatic judgment of the system may cause repeated watering in certain areas. , o...

[0003] The above scheme has certain limitations. Since the system measures the humidity values ​​of multiple single points in the soil, it cannot accurately express the humidity of the entire soil. The automatic judgment of the system may cause repeated watering in certain areas. , or the area cannot be covered by irrigation, the solution to this problem is usually to increase the number of humidity sensors, which will increase the cost of system construction, which is obviously not an ideal solution for cost-sensitive growers
