Abstract

The invention relates to the technical field of bridge monitoring data storage, in particular to a bridge digital twin data storage and tracing platform based on a block chain. According to the technical scheme, the system comprises a multi-mode tamper-proof acquisition module, a credible data preprocessing module, a component-level block chain evidence storage module, a data-driven twin modeling module and a judicial traceability verification module, wherein the credible data preprocessing module adopts an improved ICP algorithm to realize submillimeter registration of laser point cloud and a BIM model; and the component-level block chain evidence storage module realizes millisecond-level credible evidence storage based on a fragment chain architecture divided by bridge components. According to the method, through hardware fingerprint binding, multi-modal data fusion, fragment chain evidence storage, dynamic twin modeling and judicial-level evidence chain construction, whole-process credible management of bridge monitoring data from collection to tracing is realized, and data authenticity, fusion precision, evidence storage efficiency and model dynamics are remarkably improved; and a real-time and intelligent solution with judicial efficacy is provided for bridge health monitoring.
