For the solution of operation and maintenance scenarios, operation and maintenance personnel still need to judge based on the displayed data, lacking flexibility and convenience. Operation and maintenance personnel rely on paper or electronic manuals and need to accumulate a large amount of experience and training to complete various operation and maintenance operations. Summary of the Invention

[0013] Preferably, the processing module extracts operation and maintenance information and uses NLP natural language processing methods to convert unstructured data into structured knowledge, establishes relevant indexes and tags, and then uses them for data query, retrieval, data cleaning, and standardization processing.
[0014] Preferably, for data retrieval, relevant document data is vectorized and embedded into the vector database, and then the user's query statement is converted into a vectorized query to recall data with high similarity from the vector database.
[0015] Furthermore, the large language model learns common semantics from different data modalities through pictures, voices, and texts input by operation and maintenance personnel.
[0016] Preferably, the output module is used to output the operation and maintenance management suggestions of the target information system to a preset terminal or page.

Detailed Embodiments

[0031] The data processing module also includes a deduplication operation to delete duplicate samples in the original data to ensure that each sample appears only once in the training set, thereby improving the diversity of data and the generalization ability of the model; at the same time, irrelevant information and error data in the text, such as non-text content, garbled characters, etc., are identified and removed through denoising to ensure the purity and effectiveness of the training data. Data processing uses word segmentation and part-of-speech tagging to split continuous text into independent lexical units and assigns a grammatical role label, such as noun, verb, adjective, to each lexical unit.
[0032] The retrieval of data vectorizes relevant document data and embeds it into the vector database, and then converts the user's query statement into a vectorized query to recall data with high similarity from the vector database.
[0033] The creation of a vector database involves the following steps: 1) Create a model: Determine the machine learning model to generate vector embeddings; 2) Information embedding: Embed information such as text, images, and audio into vectors; 3) Data vectorization: Convert data into vector representations through the model; 4) Store metadata: Store additional metadata together with the vectors to assist in searching; 5) Create indexes: Create indexes for the vectors and metadata respectively; 6) Data storage: Store the vector data, its indexes, and metadata in the database; 7) Query preparation: Conduct searches and metadata queries through an ANN neural network; 8) Data filtering: Exclude vectors that do not meet the conditions based on the metadata; 9) Vector search: Use ANN search to find similar vectors; 10) Similarity evaluation: Evaluate the similarity between vectors through methods such as cosine similarity.

At the same time, 3 subsequent faults were successfully predicted during the system deployment, and 2 fault phenomena were accurately predicted, significantly improving the operation and maintenance efficiency and quality.
