승강장 스크린도어(PSD: Platform Screen Door)는 철도, 경전철 및 지하철 승강장 내 추락, 전동차 사이의 끼임 등의 안전사고 방지 및 승강장의 공기오염 개선, 장애인, 노약자 등의 탑승편의에 관한 문제, 승강장내의 쾌적한 환경문제 제공 등을 위해 전동차 승강장의 선단에 고정 및 가동 도어를 설치하여 승강장과 선로를 차단함으로써 이용 고객의 안전사고를 예방하는 설비를 말한다. 국내 업체들은 기술 투자를 통해 종합 제어반 및 각종 조작반, RF장치 등 상당 부분 국산화를 이루었지만, 짧은 기간 동안 승강장 스크린 도어를 설치하면서 승강장 스크린 도어 시스템의 핵심이라 할 수 있는 승강장 스크린 도어용 제어장치(DCU: Door Control Unit)의 완전한 국산화는 이루지 못한 채 외국 제품을 도입하여 설치하고 있거나 DC 모터를 적용한 제어장치를 개발하여 설치하고 있는 실정이었다. 본 연구에서는 BLDC 모터를 적용한 제어장치를 국산화하여 시제품을 제작하였고 월미도의 은하레일에 제어기를 설치하여 성능을 검증하였다.

Recently the demand of the driverless rolling stock is increasing with advancement of the stable communication technique and control technique. The automatic train operating system has advantages which takes low operating cost and is able to dispose elastically in demand. Beside it provides high safety and effectiveness because it will be able to control power, signal and communication system from Operation Control Center and the safety and effectiveness are high. The establishment of PSD, Platform Screen Door, is advanced in the goal which is passenger safety, fire protection, noise and dust reduction etc. When but, two advanced systems also have risks of operation delay and accident when two systems are not controlled smoothly. Thus, I'll introduce control method between onboard controller, door control unit in rolling stock and PSD controller to help system design.

In this paper, we introduced a simulator to visualize the driving scenery of newly developed train called the K-AGT(Korea Automated Guideway Transit). The simulator consists of mainly two parts; control system and display system. In the control system, user can control the driving speed of the K-AGT, the driving environment(day and night), the operation of the train door and the screen door and user's views(driver's view, left window view, right window view, passenger's view). In the display system, immersive driving scenery generated by stereoscopic head mount display system and 3 channel PDP display system are displayed. We are expect to utilize the system to share the idea among customer, designer and constructor and verify the operating condition of the K-AGT intuitively.

Platform screen dorr (PSD) is equipment composed of screens and doors on the platform of subways or light trains, separating the platform from the railroad. The equipment is opened and closed in connection to the doors of carriages. In order to operate the system safely, it is important to understand the characteristics of key parts. There are many parts and environmental factors such as voltage, current and temperature change but the present study measured the change rate of torque and energy changes according to the temperature of the driving motor and analyzed the characteristics of the changes and examined the features of a motor required for stable PDS and the conformability of control programs.

PSD(platform screen door) was completely installed at all of Seoul subway station(line 1~8) using 640million people per day by 2010. After installation of PSD, the influence of train induced wind at platform decreased, but is estimated to increase in subway tunnel. In this paper, train induced wind occurred by pass of subway at platform was measured and analyzed using numerical analysis by computational fluid dynamics.

Since PSD(Platform Screen Door) is set up at many subway stations, its design related to a safety becomes gradually important. Especially the intereference check with a running railway vehicle is the most important of performance indices. This study proposes a dynamic analysis models for the railway vehicle and rail. Some design parameters are considered in the models to find a correlation to the performance.

현재 많은 나라에서 지하철 역사에 승강장 스크린 도어(Platform Screen Door)를 설치하여 열차진입에 따른 승강장부의 공조환경 개선 및 승객의 안전을 확보하고자 하고 있다. 한국에서도 서울 지하철 9호선을 비롯하여 각 도시에서 PSD를 지하철 승강장부에 설치하는 노력이 시도되고 있으나, 이에 대한 검증은 전무한 실정이다 한국에서의 지하철 이용 분담율은 30％정도이며, 향후 약 50％까지 이를 것으로 예상되며, 이에 따라 PSD설비는 증가할 것으로 전망된다. 따라서 PSD 설치에 대한 지하철역사 환기 및 화재시의 배연설비에 대한 연구의 필요성은 날로 논아지고 있는 실정이다.(중략)
