Substation spatial voiceprint visual imaging method

The invention discloses a transformer substation spatial voiceprint visual imaging method, which comprises the following steps: arranging a plurality of acquisition devices according to the spatial layout of transformer substation primary equipment so as to acquire image data and voiceprint information of the transformer substation primary equipment; constructing a transformer substation spatial voiceprint directional monitoring model according to the spatial layout of the transformer substation primary equipment and the position of the acquisition device so as to determine the position of each monitored transformer substation primary equipment; image data, voiceprint information and the like of the transformer substation primary equipment and load information of each transformer substation primary equipment are collected and compared with voiceprint information stored in a voiceprint standard library under the same load information, then auxiliary information is compared, whether the operation state of the t
