The invention discloses a non-invasive identity description and intelligent identification method of an electric screen cabinet. (1) Identity description of the electric screen cabinet is constituted through substation latitude and longitude information and name nameplate image fingerprint information; the name nameplate image fingerprint information is constituted by: enabling a nameplate image of the electric screen cabinet to be imaged in a window through a manner of retrofitting the window on an image acquisition tool, receiving the imaged image by an intelligent terminal, and carrying out feature extraction; and the identity of the electric screen cabinet is enabled to correspond to a traditional input name of the electric screen cabinet, and the identity of the electric screen cabinet and the traditional input name of the electric screen cabinet are saved; (2) The intelligent identification method includes acquiring identity information of the electric power cabinet, wherein the substation latitude and longitude information and the name nameplate image fingerprint information are automatically acquired through an APP of the intelligent terminal; the name nameplate image fingerprint information is constituted by: acquiring the nameplate image of the electric screen cabinet through the image acquisition tool retrofitted by the window, carrying out imaging in the window, receiving the imaged image by the intelligent terminal, and carrying out feature extraction; and the acquired identity information is matched with a saved identity model. According to the method, transforming the electric screen cabinet is not needed.
