This invention relates to the field of
information management technology for construction projects, and discloses a cost-assisted accounting and risk
prediction system for construction projects. The
system includes a multi-source heterogeneous data sensing and access module, an atomic
work unit construction module, a topology network adaptive reconstruction module, a cost sensitivity
cascade analysis module, and a risk damping and reverse
potential energy control module. The invention achieves physical-level accounting by using the atomic
work unit construction module to calculate real-time reconstruction costs based on the measured values of physical quantities of
resource consumption and the mapping between real-time
library unit prices. The topology network adaptive reconstruction module dynamically adjusts the
network structure. The cost sensitivity
cascade analysis module quantifies the
impact of upstream node schedule deviations on downstream node costs, simulates risk
cascade diffusion, and predicts accumulated risk energy. The risk damping and reverse
potential energy control module generates virtual resource tokens for reverse transmission, and executes
physical access control when the reverse locking
signal strength exceeds a threshold, achieving automated risk blocking.
