The invention relates to the field of building intellectualization, in particular to a digital twinborn mixed cloud edge collaborative intelligent
house building group operation and maintenance intelligent
system, which establishes a digital twinborn scene
database by collecting building basic information, equipment operation data and environmental parameters, synchronizes the digital twinborn scene
database to edge equipment, and uses BIM, GIS,
Internet of Things, 5G and AI technologies to establish a digital twinborn scene
database, so as to realize the intelligent operation and maintenance of a building group. A virtual-real combined digital intelligent building scene is constructed, real-
time synchronization of a virtual scene and a physical environment is realized through AR / VR equipment, and an operation and maintenance module comprises multi-source heterogeneous data fusion, edge intelligent analysis decision, adaptive model training and iterative optimization, a
predictive maintenance algorithm of virtual-real mapping and a multi-level collaborative decision and autonomous scheduling mechanism. And the monitoring module monitors the state and operation condition of the edge equipment, provides data service and supports
visualization of management decisions, and the
system effectively improves the intelligence and
digitization level of operation and maintenance of the building group.
