Position control method and system for sintering end point

The invention relates to a method and system for controlling the position of a sintering end point. The method comprises the following steps: 1) performing grid division on a sintering area; 2) measuring data and setting parameters; 3) determining the position of a sintering end point; (4) the deviation degree of the sintering end point is judged, and adjusting measures are made according to the deviation degree of the sintering end point; (5) according to the state of the sintering end point, a sintering end point adjusting device gives an adjusting instruction according to the adjusting measures until the positions of the sintering end points of the transverse sub-regions are all distributed in the control region; according to the waste gas temperature curves corresponding to the sintering materials in the different areas, the final positions of the sintering materials in the different areas are obtained, the sintering end point deviation evaluation method is formulated, and the sintering end point deviatio
