Embodiment

[0027] This embodiment is based on the typhoon and water increase prediction of Matlab Web Server, and utilizes the combination of Matlab and Web technology to enable Matlab programs to run through Web access on computers that do not have Matlab programs installed. The web server is connected with the matlab service through the CGI extension, and at the same time, the matlab service is connected with the kernel of the matlab program. Using a web server, we can use matlab anytime, anywhere. Put the written neural network forecasting typhoon and storm surge program on the server side, then calculate the typhoon forecast information and storm surge information through HTML documents and standard forms and return them to the client, and store the calculation results in the forecasting database , for easy calling.

[0028] This embodiment adopts the ArcIMS graphic display platform: Geographic Information System (GIS) is under the support of computer hardware and software systems, ...

Abstract

The invention relates to a historical data based intelligent early warning system for typhoon and flood, comprising a database system used for storing historical data, predicting data and GIS base map data, a neural network prediction server, a WEBGIS graph display system and a WEB server, wherein the neural network prediction server is used to process the historical data to obtain prediction data which is then stored in the database system; the WEBGIS graph display system displays data in the database system graphically and publishes the data through the WEB server; the WEB server receives prediction request data inform a user client and displays the corresponding prediction result to the user in the form of WEB. Compared with the prior art, the invention has the characteristics of high prediction accuracy, intuitive display of the current storm surge information and forecasting of storm surge information. Besides, the historical data based intelligent early warning system for typhoon and flood can be taken as an auxiliary decision making system for forecasters to forecast storm surges.

Description

technical field [0001] The invention relates to typhoon and flood prediction technology, in particular to an intelligent typhoon and flood early warning system based on historical data. Background technique [0002] Natural disasters such as typhoons have brought a lot of trouble to coastal cities. However, Shanghai faces the East China Sea, backs Taihu Lake, borders the Yangtze River Estuary on the north, and borders Hangzhou Bay on the south. Shanghai's special geographical location often leads to the occurrence of "three meetings" or "four meetings". At present, the prediction of typhoon water increase is mainly based on artificial experience prediction. Due to the high human factors, the accuracy of the prediction is affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent typhoon and flood early warning system based on historical data in order to overcome the above-mentioned defects in the ...
