摘要：This study developed an environment monitoring system in order to construct a data base for understanding the actual conditions and improving problems about the air quality of subway stations, and used this device to understand the air quality of the station and analyzed the changes according to the number of passengers to execute a preliminary review related to their interrelationship.As a result of measuring the air quality of the ticket barrier and the platform of the subway station as well as outside of the station using the monitoring system, the ticket barrier and platform showed an outcome difference of similar patterns while the range of fluctuation for the platform was larger than the ticket barrier.During rush hours, the effect, according to entering passenger cars, showed to be insignificant and some sections were measured to have exceeded the indoor environment standard.This signifies that maintaining air quality during rush hours is especially crucial.In addition, during lunch hours when the number of passengers is relatively small and fixed, it overall showed to maintain a simple concentration below the indoor environment standard.Accordingly, in these times, lowering the rate of operation of conditioning equipment to minimize power and reduce the use of unnecessary energy is found to be needed.
