The invention relates to the technical field of intelligent construction, and discloses an intelligent construction
collaborative management platform and method based on digital twinning, and the method comprises the steps: firstly obtaining the practical operation data of a target
engineering machine, analyzing the data safety level of the practical operation data to generate a distributed storage path, extracting storage node identifiers in the path, and deploying the storage node identifiers to a digital twinning platform; analyzing a node storage state index, querying a data
backup demand and constructing a storage
backup framework; then identifying an access request of the
storage security framework, verifying a user identity, calculating an authority level index, analyzing an access range, and determining a platform multi-layer access regulation; then monitoring a permission change event, collecting a log, identifying a risk access behavior and calculating an access
risk index; and finally, adjusting node
encryption configuration according to the
risk index, identifying an
authority control key, and generating a self-
adaptive security policy of the target
engineering machinery on the platform. According to the invention, the integrity and safety of
construction management can be improved.
