For example, a visitor asks by voice "What tasks do hydropower station power dispatchers mainly handle in their daily work?"; 2. The speech recognition engine converts the voice into text "What tasks do hydropower station power dispatchers mainly handle in their daily work?" and transmits the text to the large language model core module; 3. The large language model core module receives the question and searches and reasons in its fine-tuned knowledge system.

The generated answer text is transmitted back to the interactive interface module, and the speech synthesis engine synthesizes the text into speech and plays it to the visitor, while the touch query terminal (if the visitor is asking questions by voice, the nearby touch query terminal can also display the answer text synchronously); 5. After listening to the answer, if the visitor is satisfied, he can continue to visit; if he has further questions, he can ask again. If the visitor is not satisfied with the answer, he can select "not satisfied" through the feedback button and input feedback opinions such as "the answer is too general, and I hope to introduce the fault judgment method in detail". These feedback information is transmitted back to the system, and the data collection and preprocessing module collects more detailed information related to the power fault judgment method according to the feedback opinions, and the large language model core module is fine-tuned and optimized again according to the new information, so as to provide more detailed and accurate content when answering similar questions in the future.
