The invention discloses a blueprint-based data large-screen visualization system interaction construction method, and belongs to the technical field of data visualization. The invention discloses a blueprint-based data large-screen visualization system interaction construction method. The method comprises the following steps: S1, creating a blueprint editor module based on a data large-screen visualization system; s2, creating a blueprint editor import node module; s3, creating a blueprint editor logic node module; s4, creating a blueprint editor and a visual editor; s5, creating a blueprint editor toolbar; s6, creating a blueprint editor configuration panel module; s7, creating a blueprint editor preview module; and S8, creating a blueprint editor debugging module. According to the method, more universal and more flexible large-screen interaction control in a large-screen visualization process can be realized.
