Abstract

The invention relates to an intelligent water and fertilizer irrigation system and method based on the Internet of Things and edge calculation. The system comprises a soil parameter sensing subsystem, a water and fertilizer parameter calculation subsystem, a water and fertilizer irrigation control subsystem and a remote state monitoring subsystem. The soil parameter sensing subsystem is used for collecting soil parameters in real time; wherein the soil parameters comprise moisture content, temperature content, conductivity and nitrogen, phosphorus and potassium content; the water and fertilizer parameter calculation subsystem is used for calculating irrigation parameters based on the soil parameters; wherein the irrigation parameters comprise required irrigation water quantity and required nitrogen, phosphorus and potassium contents; the water and fertilizer irrigation control subsystem is used for controlling the irrigation water amount and the content of nitrogen, phosphorus and potassium salt according to the irrigation parameters; and the remote state monitoring subsystem is used for monitoring irrigation state information. According to the method, the crop yield can be maximized and the resource use can be minimized at the same time under the framework of multi-objective optimization through the real-time AI calculation model, and scientific and efficient decision support is provided for agricultural management.
