Multi-Sensor System for Passenger Safety in Railway Applications

초록

Subway is a convenient and efficient public transportation system in metropolitan areas, but there are happened frequently such safety accidents as fall between a platform and a train, getting stuck between the doors, fallen passenger from the boarding platform and disastrous fire etc. In this paper, we propose a new concept of platform safety system by using multi sensor, which perceives dangerous factors of passengers on the platform automatically and informs CCR(Central Control Room) and local station employee and train driver about the situation. The proposed system consists of a set of sensors, such as video cameras and laser sensors. Each sensor monitors its own preset monitoring area in real-time whether any dangerous factor occurs in that area or not. Central data fusion unit generates more intelligent and meaningful information by using inputted the monitored results from every single sensor. Moreover, the system uses vision technique employed in ITS technology to improve detection rate.
