The invention relates to the technical field of emergency command, and discloses an emergency
command system and method based on a BIM digital base, and the method comprises the steps: building a unified
data model through expanding an IFC standard, carrying out the
semantic mapping and entity alignment of BIM building information, GIS
geographic space data,
monitoring data and an
emergency plan document, and carrying out the construction of a unified
data model. The method comprises the steps of generating an emergency
knowledge graph with BIM building information as nodes,
coupling physical
simulation and an LSTM prediction
algorithm, injecting
monitoring data into a BIM model to deduce a disaster process, outputting a risk thermodynamic diagram and an evacuation forbidden zone, and calculating space-time
accessibility of emergency resources through a
reinforcement learning model according to a deduction result. An optimization scheme including an unmanned aerial vehicle path, a personnel evacuation
route and an equipment scheduling instruction is generated, the instruction is synchronized to an
augmented reality individual soldier terminal and a mobile command shelter through an
edge computing node, a resource deployment state is labeled in real time in a BIM model, multi-
terminal operation is synchronized, the timeliness and accuracy of disaster situation sensing are remarkably improved, and the disaster situation sensing efficiency is improved. And disaster loss is effectively reduced.
