The invention belongs to the technical field of knowledge graph construction, and particularly relates to a transformer operation inspection-oriented causal relationship enhanced knowledge graph construction method and system. According to the method, information in a transformer fault processing text is deeply mined, a natural language processing technology and a deep learning algorithm are utilized, and accurate recognition and relation extraction of key entities such as fault description, reasons, phenomena, detection methods, detection results and operation and maintenance suggestions are achieved. Structured knowledge is organized and stored in a graph database, and a comprehensive, deep and easy-to-query transformer fault operation and maintenance knowledge graph is formed. By introducing a causal scientific theory, the causal relationship in the knowledge graph is remarkably enhanced, fault operation and maintenance causal knowledge with a more stable causal effect is formed, the accuracy and robustness of the causal relationship in the knowledge graph are improved, and operation and maintenance personnel can more intuitively understand complex association between fault phenomena and reasons.

The application provides a traffic signal lamp intelligent regulation system, and relates to the technical field of traffic regulation.The system comprises a traffic information collection unit and an upper computer software system;by fusing modern frontier technologies such as the Internet of Things, big data and geomagnetic field measurement, and combining scientific theories such as automatic control theory, operations research and artificial intelligence, a traffic signal lamp self-adaptive control system based on period time expansion is constructed, and the green light release time is automatically adjusted according to the real-time arrival condition of the traffic flow at the intersection.
