| In recent years, the flood disaster of middle and small rivers in China is very serious, which has been exposed to the outstanding problems of China’s small and medium rivers flood control and disaster reduction. According to the "national medium and small rivers and dangerous reservoir reinforcement, mountain torrents geological disaster prevention and comprehensive management master plan", China will use 5 years of time of flood disaster prone, densely populated areas, objects of protection of important 5000 small rivers key river protection for centralized management, from the whole to enhance flood control security level. By 2015, the whole country will complete the construction of small and medium-sized River early warning and forecasting system, to ensure that the flood control tasks of the 5186 small and medium-sized rivers can timely warning, to provide decision-making basis for the development and utilization of water resources in the middle and small rivers, flood control and safe operation of small and medium reservoirs.In this system, the real time rainfall, meteorological data collection, storage and management as the basis, the use of advanced water technology and information technology, to the small river flood forecasting business as the core, the integration of mountain flood warning system and water resources management system, establish the service in small and medium-sized rivers, flood forecasting, hydrological station network management, spatial query the information service platform and consultation decision support environment, to ensure that the river floods can be timely warning, improve the accuracy of flood forecasting and forecasting period, enhance the hydrological service capacity and service level, to provide decision-making basis for the safe operation of river water resources utilization and protection, flood control and reservoir.B/S structure is used and based on SOA technology to realize the whole system, using Server SQL 2008 as the database server, the remote data receiving and processing, remote monitoring, system setting management, flood forecasting, flood forecasting and information retrieval are 6 functional modules. In the telemetry data receiving processing module, realizes the function of flood forecast data communication, data decoding and data storage; in telemetry monitoring management module, the realization of the self surveillance, monitoring of rainfall, water level monitoring and condition monitoring four functions. Among them, since the surveillance is responsible for real-time monitoring and self-reported information through the screen alarm output; responsible for the monitoring of rainfall monitoring and real-time rainfall information through the screen alarm output; water level monitoring is responsible for monitoring of the real-time water level information and through the screen alarm output; working condition monitoring for monitored real-time condition information through the screen and alarm output; set in the system management module:the realization of the system parameters, the parameters of RTU management functions (including the increase, modify, delete) in flood forecasting; parameter management module, the implementation of basic data and empirical data of flood forecasting management (including add, modify and delete), including the time management of flood forecasting and flood forecast release management unit 2 functions; in the flood forecasting module, realizes the prediction of data dissemination and query, including precipitation forecasting and river hydrological forecasting function; in the information retrieval query module, realized for query display and Excel reports operating functions for all hydrological information.Each functional module data sharing and functional interoperability, based on all kinds of information provided by other systems, is a scientific basis for flood forecast, forecast and analysis, and provide a scientific basis for flood control departments with rapid and accurate. |
