The invention discloses a hydrological
dynamic monitoring and
analysis method based on an entity map, and relates to the technical field of hydrological
dynamic monitoring and analysis based on
the Internet of Things, and the method comprises the steps: constructing a hydrological entity map of a target
watershed, abstracting a hydrological object into an entity, defining a time-space association relation of the entity, and after a
system responds to a request, carrying out the analysis of the entity map. A polymorphic monitoring view strictly corresponding to the entity map is displayed, when a user operates a specific view, the
system traverses the map from a root node entity and dynamically outputs a monitoring result, and intelligent guide analysis is achieved. The
system supports unified conversion of multi-source heterogeneous hydrological data, and the time-space relation clearly covers key associations such as space inclusion, flow direction, monitoring dependence and event triggering. Each hydrological
entity model integrates multi-dimensional attributes, supports from basic monitoring to intelligent analysis and early warning decision, and realizes unified fusion of hydrological
monitoring data, precise modeling of a time-space relationship, dynamic guidance of an analysis path and effective support of early warning decision.
