APPARATUS AND METHOD FOR INFERRING ATMOSPHERE ENVIRONMENT OF UNDERGROUND SPACE USING STATISTICAL ANALYSIS

摘要

A device and a method for estimating an atmospheric environment of underground space with a statistical analysis are provided to estimate a pollution concentration based on a multiple regression analysis by using representative measurement variables such as temperature, humidity, carbon dioxide, and visibility. A measuring module(210) measures the representative measurement variables of the atmospheric environment of the underground. A measurement signal processing module(220) receives and stores the measured variables. An analyzing module(230) estimates the pollution concentration of the underground by receiving data processed in the measurement signal processing module and using the statistics analysis. The measuring module includes a temperature, humidity, carbon dioxide, and visibility sensor(211-214). The measurement signal processing module includes a signal recognizer(221) receiving the variables, a data amplifier(222), a noise filter(223) removing noise from the amplified data, and a data converter(224) converting the filtered data into digital data.
