At present， there are some problems in domestic hydrometric stations， such as single function， disconnection of information collection and analysis， low coordination of system functions. To ameliorate these problems， an integrating hydrological monitoring， hydrological forecast， and hydrology and water conservancy calculation hydrological intelligent robot is designed. The robot has the following functions： self-inspection and automatic monitoring of hydrological monitoring equipment； real-time hydrological forecasting through communication technology and other historical information and observation information fusion and data assimilation； carrying out water conservancy evaluation intelligently； generating scheduling decision-making plans， and issuing forecasting and warning information. The intelligent robot system realizes a friendly human-computer interaction platform by means of language recognition and synthesis， which can simulate the thinking mode of hydrologists， change the one-way transmission mode of traditional equipment measurement， reporting， and calculation， and dynamically changes the measurement mode， position and frequency according to the rationality evaluation of forecasting and calculations. The proposed hydrological intelligent robot structure can replace the related functions of hydrological personnel at the basic station and in charge of flood control， reduce the labor intensity of hydrological work， and provide an important technical support for promoting the transformation of water conservancy undertakings to modernization and intelligence.
