A cultural heritage immersion warning method and system based on multi-source precipitation data
By fusing multi-source precipitation data and using a hydrological-structural coupling model for heritage sites, the problem of high false alarm rates in early warning caused by single data sources has been solved. This enables accurate flood warnings for cultural heritage sites, distinguishing between normal fluctuations and dangerous flooding, and providing personalized risk assessments.

AI Technical Summary
In existing technologies, a single precipitation data source cannot accurately characterize the actual spatial distribution of precipitation under the micro-topography and microclimate of cultural heritage sites, resulting in a high rate of missed or false alarms in flood warnings. Furthermore, it ignores the process of precipitation transport, adsorption, and storage within the heritage material itself.
Using multi-source precipitation data fusion technology, spatiotemporal continuous three-dimensional precipitation field data is generated. Combined with the hydrological-structural coupling model of the heritage site, the seepage and stress response process of precipitation in the heritage body and its foundation is simulated. A seasonal background baseline and a self-adjusting baseline of the heritage body materials are constructed, and an inundation risk index is determined for early warning.
It enables accurate early warning of cultural heritage, reduces false alarm rate, can distinguish between normal fluctuations and dangerous flooding, and provides personalized risk assessment.
