The invention discloses a localized protection information viewing method based on off-line speech recognition. The method comprises the following steps: establishing a localized protection information element list; establishing a localized protection offline voice command basic word bank; establishing a localized protection off-line speech recognition pronunciation extension word bank; selectingan interval localized protection device according to the SCD file; accessing a localized protection private network and starting off-line voice recognition; identifying a local protection informationviewing command word; and displaying the successfully identified localized protection information to view the localized protection information corresponding to the command word. According to the method, the local protection private network is accessed; on-site protection field testing and protection information checking during operation and maintenance are rapidly achieved based on voice input, the problem that an on-site protection management unit is separated from on-site protection, and on-site protection information and states are inconvenient to check in time during testing operation andmaintenance is solved, and on-site protection and testing operation and maintenance efficiency and convenience are effectively improved.
