Key technologies for data exchange in the national groundwater monitoring project(water conservancy)
Based on typical four-tier exchange scenarios(Ministry of Water Resources-Basin-Province-City)within the water conservancy industry,and Ministry of Water Resources and Ministry of Natural Resources'real-time exchange and sharing of groundwater monitoring data,this study addresses the need for trustworthy exchange of massive,heterogeneous data across complex network conditions.It proposes four technologies:adaptation and integration for long-distance transmission of multi-source data,distributed collaborative scheduling for massive data exchange,bidirectional trusted exchange using security-isolated network gates,and integration and sharing of massive,heterogeneous data between two departments.These technologies are summarized based on core structure and principle levels,and practical operational experiences are used to propose future upgrade recommendations.Currently,these technologies are widely applied and promoted within the national groundwater monitoring project(water conservancy).Application results demonstrate that these key data exchange technologies enable effective data exchange and sharing under complex conditions,facilitating real-time collection,reporting,sharing,and exchange of groundwater monitoring data between two departments.This also provides technical support for local groundwater monitoring stations to interface with basin sub-centers and the national center.
