Tang Guang-ming · Automation in Water Rescources and Hydrology · 2006
In order to improve the working efficiency and level of hydrological survey and forecast of Tianjin Hai River Gate hydrological station, the hydrological survey and control system of Hai River Gate digital hydrological station was founded .The system is constituted of six subsystems, i.e automatic subsystem for water level measuring and reporting, automatic subsystem for gate monitoring, automatic subsystem for flow monitoring, automatic subsystem for meteorological multi-parameters measuring and reporting, video monitoring subsystem and central control subsystem. During more than one-year operation, every subsystem performes normally. Through contrasting analysis, it is shown that the measurement precision of every hydrological apparatus meets the demand of hydrological measurement criterion. The system provides valuable experience for the subsequent digital construction of Tianjin hydrological station net.
