AI Technical Summary

Technical Problem

Existing technologies struggle to accurately estimate solar radiation and Wet Bulb Globe Temperature (WBGT) without direct measurement of solar radiation, especially when using sensors that only measure solar irradiance, leading to complex calculations and increased computation costs.

Method used

A method and system that estimates solar radiation using a regression equation derived from solar irradiance and observation time, focusing on clear days at solar noon, and uses this estimation to calculate WBGT, incorporating temperature, relative humidity, and wind speed, with the option of machine learning models for improved accuracy.

Benefits of technology

Enables accurate estimation of solar radiation and WBGT, allowing for timely heatstroke warnings by simplifying calculations and reducing computational costs, while utilizing existing sensor capabilities.

Abstract

In an information processing method according to the present invention, a computer executes processing for acquiring an amount of sunlight at an observation point and observation time point information indicating an observation time point of the amount of sunlight, and estimating the amount of solar radiation at the observation point on the basis of the acquired amount of sunlight and observation time point information. Preferably, the amount of solar radiation is estimated on the basis of the acquired amount of sunlight and observation time point information by using a regression equation indicating the relationship between the observation time point and a ratio of the amount of solar radiation to the amount of sunlight.
