in the preset search box, the corresponding marked sub-number group, i.e. sub-coordinate (X m-i ，Y m+i )；
Then according to the formula W= (X) m-i +Y m+i ) And/2, obtaining corresponding marked parent numbers W, wherein W is greater than 0, then determining the storage partition in a plane rectangular seat according to the coordinate values of W as management coordinates on the X axis and the Y axis, namely (W, W), and then determining the storage partition in the plane rectangular seat according to the coordinate values of (W, W)Positions in the frame;
and searching corresponding storage points in the determined storage partition, and extracting project data from the corresponding storage points.
