Automatic irrigation water pump control method and controller

The invention discloses an automatic irrigation water pump control method and a controller, and the method comprises the steps: obtaining a current to-be-irrigated crop area grid, building an irrigation water flow path of a crop water pump according to the current to-be-irrigated crop area grid, and generating primary irrigation line information; the method comprises the following steps: constructing an irrigation flow prediction model, obtaining real-time irrigation flow data information based on the irrigation flow prediction model, obtaining coordinate position information of a current to-be-irrigated crop, and obtaining spatial distribution data information of a current coordinate position based on the coordinate position information of the current to-be-irrigated crop; the irrigation process of the crop water pump is automatically controlled, quantitative errors of crops under manual operation can be avoided, the model is predicted, motion trail control and optimization of the irrigation process are furt
