An intelligent safety closed-loop control model for hydropower projects

With the intelligent transformation of engineering safety management, traditional safety control models struggle to meet the demands of the intelligent era because of their limited generalizability, incomplete frameworks, and insufficient control indicators. To address these challenges, this study proposes an intelligent safety closed-loop control (ISCC) model. Following the principles of “full perception, accurate analysis, real-time control, and continuous optimization”, the model establishes phased control indicators to identify and rectify safety hazards. It examines the characteristics of key management elements, including workers, machinery, the environment, and management processes, and introduces intelligent implementation methods for safety management based on the ISCC model. Additionally, a multiunit synergistic intelligent control approach is developed to enhance safety hazard identification and rectification. The ISCC model is successfully applied to the safety management of concrete pouring at the Baihetan hydropower project. The results provide valuable insights for advancing intelligent safety management in infrastructure engineering construction.
