Title: Hua Liu: Inventor of a Concrete Dam Monitoring Method
Introduction
Hua Liu is an inventor associated with Kunming City, China. His work includes a patent application focused on monitoring key parts of concrete dams and detecting anomalies in their operation.
Latest Patents
Liu’s listed patent is “Partition Monitoring Method and Model for Concrete Dam Operation Key Part.” The method uses time-frequency features from monitoring data to divide key dam areas into partitions. It then organizes measurements from different monitoring instruments into a graph structure, capturing relationships across time and variables. A graph attention network helps represent these relationships, and the resulting features are used to calculate anomaly scores. The approach is designed to support cross-checking among multiple measurement points and reflect the dam’s structural integrity and spatial distribution.
Career Highlights
Liu is associated with Huaneng Lancang River Hydropower Inc. and Hohai University. His listed patent count is 1 patent.
Collaborations
Hao Chen and Haibin Xiao are identified as Liu’s coworkers.
Conclusion
Hua Liu’s listed invention applies time-series analysis and graph-based learning to concrete dam monitoring, with the goal of improving anomaly detection through coordinated measurements.
