The emergence of sensor networks as one of the dominant technology trends in the coming decades. These networks are likely to be composed of hundreds, and potentially thousands of tiny sensor nodes, functioning autonomously, and in many cases, without access to renewable energy resources. Cost constraints and the need for ubiquitous, invisible deployments will result in small sized, resource-constrained sensor nodes. Ubiquitous sensor network(USN) module with 4 kinds of air quality monitoring sensors was developed for indoor environment monitoring system in subway stations. The module has various enlargement for various kinds of sensors such as temperature sensor, humidity sensor, CO₂ sensor, particulate sensor. To reduce the measurement error of sensors, we calibrated each sensor using standard gases and particles. The development wireless node is very convenient to be installed in the subway stations. USN is expected to be used for the cheap and easy way for indoor air quality monitoring.

As the standard of living is higher, the passengers using public transportations desire better qualities of environment as well as more comfortable indoor environment. In case of train, the passengers’ comfort in passenger cabin is one of the most important elements to be competitive with other transport systems. The indoor air quality of the cabin should be managed properly, because many passengers travel for a long time in the small space of 144 ㎥. For proper management of the air quality, the heating, ventilation and air conditioning (HVAC) system is required for the ventilation of the compartment. To maintain comfortable environment in the compartment, the automatic ventilation system is needed to exchange the indoor air with fresh air or clean indoor air. In this study, we investigated the indoor air quality (PM-10, CO₂, and VOCs) in the compartment of train. In addition, type and pattern of PM-10 has been analyzed through the clustering analysis. Based on the analysis, we could found that the fine particulate matters in the compartment can be a serious hazard to human. To control the concentration of PM-10 and CO₂ air cleaners were developed. Through this study, it is expected that people who take a train will be in a more comfortable environment.

Objective of this study was to characterize PM10 sources on subway tunnels and development of simple particulate matters measuring device based on wireless sensor network. A new wireless sensor module PMX has been designed and manufactured to measure PM10 and PM2.5 simultaneously. The measurements have been conducted at a specific subway station on the Seoul metro line. The accuracy of the device was verified and compared with commercial measuring device based on weighting method.

Because the indoors spaces of the passenger cabin is generally airtight to secure the safety of passengers and enhance the efficiency of the cabin air conditioning performances, the contamination pattern of them are largely similar to that of general indoor spaces. Therefore, continuous supply of outdoor air is required to keep the amenity of indoor space. Heating, ventilation, and air-conditioning (HVAC) system is composed of air cleaning filter, heater and air conditioned, blower and ducts. To achieve the clean indoor environment, an integrated control of each HVAC equipment are required. In this study, we developed the air cleaning system to enhance the amenity of the railroad passenger cabin.

In this study, we tested hybrid pilot system combined with soil vapor extraction and bioventing methods on the contaminated railroad soil. So, we found out the remediability and operating conditions. Air permeability(k) and gas phase(O2/CO2/VOCS) level trend are very important to determine the remediation rate of the contaminated sites. Throughout hybrid pilot test on different conditions, the range of air permeability(k) was 1985~1194 darcy. The tests results in hybrid system was appropriate on this test sites, and the suitable injection air flow rate was 3.5㎥/hr. So, we suggested a basic data for the remediation and management of contaminated railroad soil.
