Embodiment Construction

[0033] Solar activity forecasting is a massive data analysis, and the computer solar activity forecasting system of the present invention is to set a forecast module and a massive database in a server system (see figure 1 ), the server has a man-machine interface and is connected to the Internet, and the forecast module is connected with the database and the server; three forecast models are established in the forecast module, namely the flare forecast model, the proton forecast model and the radio flux forecast model (see figure 2 ).

[0034] Proton forecasting model, based on SVM:

[0035] Selection of characteristic parameters: select six parameters including current proton occurrence, sunspot area, sunspot magnetic classification, sunspot group McIntosh classification, sunspot position, and current maximum flow of protons.

[0036] SVM-based forecasting model: choose SVM (Support Vector Machine, Support Vector Machine) to build a proton forecasting model. SVM is a new ma...

Abstract

A computer solar activity forecasting system comprises a forecasting module in a system containing a server with human-machine interface and a mass data base, wherein the forecasting module is composed of a radio current forecasting module established based on ARIMA module, a proton forecasting module based on SVM and a flare forecasting module based on multiple discrimination pattern, a network station automatic data downloading module, a mail automatic data receiving module, a conventional sending module and an unconventional sending module, and a timing start-up forecasting module controlled by the timer in the server. The said system solves the problem that the data processing amount is large and the time and vigour is squandered during forecasting the solar activity and quickly and accurately forecasts the solar activity of mid long term and forecasts the solar activity of short term which is difficult to forecast in days of old and has great applied cost for preventing the solar acute activity from influencing the human living and agricultural production and performing scientific study.

Description

technical field [0001] The invention relates to a computer application system, in particular to a computer solar activity forecasting system. Background technique [0002] The sun is a planet closely related to human life, and the sun is in non-stop activities, and any activities of the sun: such as the activities of sunspots, the activities of flares on the surface of the sun, the activities of the sun’s magnetic field and the activities of the sun’s X-current Directly affect the climate change of the earth, and directly affect the life and production of human beings on the earth. The observation and monitoring of solar activity has always been a major task in the astronomical community, and the purpose of monitoring is to analyze the characteristics of solar activity, and then make accurate forecasts for possible future activities of the sun. [0003] However, the sun's activities are very frequent, and the monitoring of solar activities is almost uninterrupted. The workl...
