Accident Protection Equipment for Railway Platform using novel LaserRadar Sensory system

초록

Many casualties are being occurred due to many missteps, etc. at the railway platform, and the number of cases occurred is being increased. Thus recently, the PSD (Passenger Screen Door) is being installed in the metropolitan rapid transit section in Korea to prevent casualties at the platform fundamentally, and to solve the environmental problem of platform in case of the underground station building. Although this PSD can prevent public casualties at platform fundamentally, it is impossible to install it at whole station buildings since its installation cost is high. This paper proposes the safety equipment using LaserRadar sensors for the prevention against casualties of passengers at station buildings where the PSDs are not installed like this. The safety equipment using LaserRadar sensors is the safety equipment making an approaching train stopped if the falling object is a person by detecting the obstacle at platform through, and it has the merit possible to apply it to station buildings not only in the underground section but also in the ground section since it may detect accurately under ambient environmental elements such as the snow, rain and yellow dust, etc. also. We manufactured a prototype of the safety equipment to reduce public casualties at platform by using LaserRadar sensors and carried out its performance test, and the result is presented in this paper.
