description The invention discloses a method and a device for realizing map synchronous interaction on a spliced screen. The device comprises a main control node, a plurality of rendering nodes and display screens corresponding to the rendering nodes, the main control node is used for acquiring main map parameters of the main map and calculating sub-map parameters; each rendering node is used for generating asub-map according to the received sub-map parameters, and obtaining cursor operation information corresponding to an interaction operation when the interaction operation triggered based on the sub-map is detected; the main control node is also used for calculating target sub-map parameters according to the cursor operation information and the main map parameters; and each rendering node is also used for updating the sub-map according to the target sub-map parameter and sending the updated sub-map to the corresponding display screen for displaying. When the interactive operation is detected, the cursor operation infor
