Automatic secondary circuit design method, device and system based on screen cabinet interface model and typical design template

The invention discloses a secondary circuit automatic design method, device and system based on a screen cabinet interface model and a typical design template, and the method comprises the steps: building the typical design template of a secondary circuit according to the voltage class, the main wiring form and interval information; the interval information of the typical design template is stored in an interval relation database, and the connection relation of screen cabinet interfaces related to the typical design template is stored in an information flow database; function partitioning and feature extraction are carried out on a screen cabinet logic loop according to the characteristic of secondary loop design function partitioning, and a screen cabinet interface model containing a logic function area is established; based on the typical design template and the screen cabinet interface model, through step-by-step analysis mapping between the templates and the models, automatic matching of the logic functio
