The Research And Utilization Of The Data Management Platform Of Hydrology And Water Resources Monitoring

The monitoring data of hydrology and water resources is one of the most important water conservancy basic information and strategic resources in the 21st century in our country. It is conducive to the macro-decision of government, the national economy of development and the information advancement of hydrology and water conservancy by scientific managing and applying these data. Because of the deficient research in hydrology and water resources information work, the level of monitoring data management is very low for long. The research on information management is also behind the increasing of demand. This paper studies the development and use of the hydrology and water resources data management platform software system by draw on the experiences of international in using the PDM platform software system.The development and use of data management platform is basing on the acquisition, management and applying of the monitoring data of hydrology and water resources. It's using the advanced computer and network technology such as . net, 0racle9i, XML technology, Web Services and so on. According to the demand of practical work, it manages the real time monitoring data by establishing spatial database and use GIS and wireless technologies. The database is the center of the data application service system. It provides the functions of inquiry, statistics, analysis and appraisal for users by developing the spatial database and monitoring data of hydrology and water resources database. It carries out the long-distance access and management by using WebGIS platform into the multi-dimensional electronic map of hydrology and water resources. The safety control system is mainly composed of the network security system, the application security system and the data security system and so on. It provides the good function of fault-tolerant and backup and guarantees the system safe, stable and reliable in application.
