The invention provides an intelligent
early warning system fusing
Internet of Things sensing data and
a domain knowledge graph, aiming at the problems of data islands, high
false alarm rate, response
lag and the like of a traditional park
early warning system, and is suitable for park safety prevention and control in industries such as
chemical industry, logistics, manufacturing and the like. The
knowledge graph is an ideal tool for modeling connection between objective objects in the real world, the data island problem can be effectively solved by constructing the
knowledge graph oriented to the smart park safety management field and fusing an intelligent
reasoning algorithm, and the accuracy and timeliness of park risk early warning are remarkably improved. Specifically, a whole set of pre-
warning system is designed from bottom to top in three aspects of multi-
modal knowledge graph modeling, a three-level pre-warning
inference engine and a self-
adaptive optimization mechanism, and the park pre-warning requirements which meet current intellectualization and manpower cost saving are constructed. The multi-
modal knowledge graph relates to six types of ontology concepts, comprises different data types, and comprises an equipment topological relation, environmental parameter association, an
emergency plan, risk analysis,
attack behavior
simulation and an asset attribute model. The third-level early warning reasoning comprises rule reasoning, sub-graph matching reasoning and link prediction reasoning. The self-
adaptive optimization technology aims at constructing a feedback learning mechanism, incorporating each early warning
processing result into a knowledge graph, and continuously optimizing the object relation weight. In an early warning analog
simulation experiment, the scheme of the invention realizes the effects of reducing the
false alarm rate by 42% and improving the
emergency response speed by 60%, and the feasibility and effectiveness of the scheme are proved.
