AI Technical Summary
Existing technologies for large variable displacement sprinkler irrigation machines suffer from large spraying errors and cannot effectively solve the problem of sudden changes in water depth between adjacent management areas, especially when the sampling intervals are large and unequal, resulting in insufficient sprinkler irrigation accuracy.
By employing surface radiation grid discretization, inverse distance weighted interpolation, and area weighted equal division, the known water demand information is diffused to the entire plot plane through grid division of the sprinkler irrigation area, and the depth of sprinkler irrigation water in each management area is calculated.
It achieves a smooth transition in water depth during sprinkler irrigation, reduces abrupt changes in water depth, improves sprinkler irrigation accuracy, and ensures the accuracy and uniformity of water demand within the management area.
