the pouring plan list comprises information such as pouring date, bin codes, square amount, intermission period, age, adjacency and maximum height difference; meanwhile, information such as daily pouring strength, monthly pouring strength, total pouring unit number and the like is counted;
the age refers to subtracting the pouring time of the current unit or the planned pouring time according to the current time; the intermittent period is the planned pouring date of the unit to be poured minus the pouring date of the lower layer, and the intermittent period must be controlled within a reasonable range;
the adjacent height difference is based on the position of the current bin, the height difference between the current date progress image and the left dam section and the right dam section is calculated, and the height difference is positive when the current date progress image is higher than the adjacent dam section and negative when the current date progress image is lower than the adjacent dam section;
