The invention discloses a hydropower station intelligent inspection system. The system comprises a data layer which is used for the collection, convergence, analysis, calculation and storage of the operation parameters and the environment data of the hydroelectric equipment, the real-time recognition, analysis and diagnosis of the images and audio data, and the transmission of the data to an application layer; an application layer which interacts with a user and is used for service agency, engine scheduling, integrated management, identity authentication and authority control; and a client which performs visual display, alarming, linked playback and event recording of the historical data according to the data of the data layer and the application layer. According to the present invention,the state of the hydroelectric equipment is monitored through image acquisition, audio data acquisition, data linkage, data recording and playback, and the machine identification of equipment defectsand faults is realized; the data acquisition and analysis are carried out through the inspection robot, the visible light camera, the infrared thermal imaging device and the audio acquisition device,and the manual inspection work of the hydropower station is replaced.
