<p>An image frame control method used for tunnel movement image display comprises the following steps: A10: sequentially disposing multiple display light pillars on a tunnel in a side-by-side manner, and the display light pillars receiving frame synchronizing signals sent by a frame controller; A20: the frame controller recording coordinates of each display light pillar and calculating the sending time of the frame synchronizing signal of each display light pillar according to an operation speed of a locomotive; A30: when a train sequentially passes through the display light pillars, the frame controller correspondingly sending frame synchronizing signals to the display light pillars, the display light pillars starting to scan first to nth lines of display data of one frame by using the display light pillars as starting points, so as to synchronizing multiple images and the train and sequentially displaying and forming movable images; and A40: if the train moves at a low speed, adding a plurality of display light pillars between every two adjacent display light pillars so as to eliminate image flickers. In the method, flickers are eliminated by adding frames when a train moves at a low speed, and images are adjusted and controlled very conveniently.</p> |
