Design of Data Acquisition Scheme for Cross-boundary Section Based on Wireless Sensor Network: A Case Study of Guanting Reservoir in Yongding River Basin

In order to fully reflect the temporal and spatial variation characteristics of water quality change in the basin and realize the complete collection of cross-sectional data, it is necessary to improve the time and space precision of monitoring data, expand the monitoring time and space scope, expand the monitoring time and space threshold, ensure the full-time comprehensiveness of monitoring, and realize the comprehensive monitoring of high frequency and multi-time. Under this premise, water quality monitoring network based on wireless sensor becomes a feasible solution. Taking Guanting Reservoir in Yongding River Basin located at the junction of Hebei Province and Beijing as an example, this paper compares and discusses the advantages of on-line water quality monitoring network scheme based on wireless sensor network in determining transboundary pollution sources and strengthening transboundary pollutant monitoring compared with existing fixed station monitoring points.
