Three-dimensional digital water curtain control method

The invention discloses a three-dimensional digital water curtain control method, which comprises the steps of firstly determining characters or patterns to be displayed on water columns ejected by electromagnetic water valves, the electromagnetic water valves in a row are sequentially defined as y1, y2, y3, etc. and yi, columns of the electromagnetic water valves are sequentially defined as x1, x2, x3, etc. and xi, then defining digital I/O ports {6, 8, 10, etc., 2i, etc. and 2i+4} of a singlechip microcomputer as a one-dimensional array pinx[i], connecting a signal output port of a driver to i lines of the electromagnetic water valves x1, x2, x3, etc. and xi, defining digital I/O ports {5, 7, 9, etc., 2i+1, etc., and 2i+3} of the singlechip microcomputer as another one-dimensional array piny[i], connecting the signal output port of the driver to i lines of the electromagnetic water valves y1, y2, y3, etc. and yi, assigning a module to one-dimensional arrays HLxi[i] and HLyi[i], and executing the one-dimensional arrays HLxi[i] and HLyi[i] in a repeated circulation mode, that is, all of the one-dimensional array HLxi[i] is executed once at every time when the one-dimensional array HLyi[i] is executed.
