Abstract—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.
