Design And Implementation Of Dalian Area Meteorological Disaster Information Sharing System

With the continuous development of meteorological service in China, the weather forecast and disaster service work is more and more important. At the same time, the global industry and other factors, the global climate conditions are deteriorating, the trend of climate warming, frequent extreme weather events, people affected by the large production life, the national economy has been varying degrees of loss. Dalian is located in the southern tip of Liaodong peninsula, and the topography is complex, affected by the monsoon circulation. Therefore, Dalian is one of the national meteorological disasters happen more frequently. Establish Dalian meteorological disaster information sharing system is helpful to promote the development of Dalian disaster prevention and mitigation work better and faster.System development and design to comply with the specifications, accurate meteorological disaster information management basic principles. Accordance with the requirements of actual interaction system development using ASP.NET and VB6.0 by use of two kinds of language, the administrator in the data storage and user query in data interaction of C/S and B/S mode respectively. The system database for SQL SERVER 2008 database. System requirements analysis from business process can be divided into business application requirement analysis and the analysis of functional requirements. Adopting the combination of UML modeling and use case diagram, scientific and standardized describes the weather business users on the system of management and operation. System design phase, according to design principle to draw the whole frame structure and functional module chart, special design gives the detailed design of user query function, pointed out the query shows the way. System by adopting the idea of e-r diagram, database design is divided into conventional ground observation database and two kinds of meteorological disasters database, record the conventional meteorological observation information and disaster information.This system by collecting the Dalian municipal civil affairs bureau, the bureau of meteorology, transport, water authority departments such as meteorological disaster information, according to the specification requirements of the meteorological disasters ceremony, compiled from 1949 to 1949 in the first half of the Dalian area of storms, drought, frost, hail, wind and thunder and lightning, all the data of meteorological disaster, and after finishing after unified format specification in the backend database. According to different user permissions, the system realizes the administrator of the data standard and safety management, other users can implement the data query, export and statistics. The query display mode histograms, line chart and so on the many kinds of styles. The system has realized the well dalian meteorological disaster information sharing service function, conforms to user operation and using habit to meteorological operations. System of forecasters timely understand and grasp the region information such as time, frequency of meteorological disaster, to guide forecast, early warning and decision-making service work with strong practical significance.
