Urban operation data sensing method and system based on digital twinning

The invention relates to the technical field of data processing, and provides a digital twinning-based urban operation data sensing method and system, and the method comprises the steps: obtaining the operation data of a plurality of types of data sources in a data twinning model until the current moment, and obtaining the occurrence time, occurrence place and event type of a plurality of events; obtaining an associated slice of each event in each type of data source; obtaining a linkage coefficient of each event; obtaining the interpretability of each type of events; the recall rate of each data source combination for each type of events is obtained; obtaining a positive class sample probability of each class of data sources to each class of events; obtaining an information carrying rate of each type of data source to each type of event; obtaining the perception probability of each type of data source; and obtaining a sensing sequence based on the sensing probability of the data source, and obtaining a plura
