Embodiment Construction

[0029] The present invention discloses a storm surge disaster early warning system based on time sequence analysis. The specific implementation will be described below with reference to the drawings.

[0030] Such as figure 1 As shown, a storm surge disaster early warning system based on time series analysis receives remote monitoring data in real time, performs early warning analysis on the monitoring data sequence, and performs early warning and auxiliary decision-making based on the analysis results. It is characterized by including database system, early warning model analysis, auxiliary decision system display, Web server and user management. The early warning prediction model analysis module is mainly to preprocess the observation data in the database, and perform piecewise linear representation of the time series data to achieve the purpose of dimensional compression, and then similarly match the real-time monitoring data with the historical monitoring data, and based on th...

Abstract

The invention discloses a time sequence analysis-based storm surge disaster early warning system, which comprises a database server, an early warning prediction model analysis module, an assistant decision making system, a Web server and a management user, wherein the database server stores historical monitoring data, real-time monitoring data, basic geographic information data, emergency plan data, related calculation model data and early warning data; the monitoring data and the early warning data are time sequence data; the early warning prediction model analysis module is mainly used for preprocessing the data, piecewise linearly expressing the time sequence data to fulfill dimension reduction and compression aims, performing similarity matching on the time sequence data and the historical monitoring data, and performing disaster early warning according to a similarity matching result; and the assistant decision making system displays assistant decision making information on the basis of geographical graphic information, and displays the assistant decision making information to a client of the management user through the deployed Web server.

Description

Technical field [0001] The invention relates to a marine storm surge early warning system based on time sequence analysis, in particular to a system and method that fully utilizes historical monitoring data to analyze and early warning current monitoring data. Background technique [0002] With the rapid development of the global economy, frequent climate changes have led to global ocean acidification, rising sea levels, and frequent ocean disasters. Marine disasters mainly include: storm surges, tsunamis, wave and coastal erosion, red tides, etc. Among them, the frequency of storm surges and the disasters caused are the first in my country. The losses caused account for more than 60% of the losses of marine disasters, and the number of casualties exceeds Land disasters such as earthquakes. [0003] At this stage, the methods used for marine disaster forecasting basically adopt numerical forecasting methods. Numerical forecasting methods mainly use large-scale, fast electronic com...
