We have evaluated the structural stability of a platform screen door due to train wind pressure. The platform screen door was installed at the ground and underground station and had 65 meters in length. Also, the platform screen door was a safety device because it was placed between the train and the platform. The finite element analysis was used to calculate the stresses and deflections of platform screen door caused by wind pressure using ANSYS 10.0. Quasi-static analysis was introduced to save calculating time and check quickly structural performances when compared to those of transient analysis. The results show that structural stability of the platform screen door under train wind pressure is proven and quasi-static analysis can quickly check the structural integrity of platform screen door.

In this study, transient and quasi-static analysis were done for the evaluation of structural integrity of the platform screen door due to train wind pressure. Fluent 6.0 was used to calculate the train wind pressure, and Ansys 10.0 was used to evaluate the structural stability of platform screen door due to train wind pressure. Transient analysis was used to check the design requirements of platform screen door, and quasi-static analysis was introduced to save the calculating time and check quickly structural performances when compared to those of transient analysis. The results show that structural stability of the platform screen door under train wind pressure is proven and quasi-static analysis can quickly check the structural integrity of platform screen door.

Platform Screen Door System (PSD)는 지하철 승객의 편의 및 안전을 위해 설치되기 시작하였고, 현재 전국 9개 운영기관이 관리하고 있는 824개 역사 중 전체의 71.8%에 해당하는 592개 역이 PSD를 운영 중에 있다. 본 연구에서는 전동차 정차 위치에 따른 PSD와 전동차 가동문 사이의 개폐율 변화를 분석하였고, 수도권 지하철을 운행 중인 기관에서 제공받은 재차인원 자료 분석 및 피난시뮬레이션을 통해 각 역사별 피난소요시간을 산정하였다. 연구결과 승객이 매우 혼잡하게 밀집되는 일부 고밀도 역사에서는 PSD 개폐율에 따라 매우 위험한 상황이 초래될 수 있음을 알 수 있었다. 특히 정위치에서 7 m 벗어난 곳에 정차할 경우 PSD의 고정 안전보호벽과 맞물려 열차 출입문 절반 이상이 폐쇄되는 것으로 분석되었다. 이러한 문제점을 개선하기 위해 기(旣) 설치된 PSD 고정안전보호벽을 모두 개폐 가능한 비상문으로 교체 및 개량하는 것을 제안한다.

Platform Screen Door System is a facility on platform to separate platform from track, having automatic sliding door structures interlocked to opening and closing of train door with integrated control unit. When a train comes to a stop at a designed position at a station, onboard ATC/ATO system transmits train berth signal to wayside signaling system. In case of automatic/driverless operation, opening and closing of the Platform Screen Door will be controlled by wayside signaling system. Unfortunately, we often see the case in news that passengers fall into track and their contact with train lead to critical accidents. However, passengers will be free from such accidents on the platform with the Platform Screen Door System. Especially during the rush hours, to ensure passenger's safety and smooth getting on & off, it is necessary to arrange. some station staffs on the platform without the Platform Screen Door System. On the other hand, the Platform Screen Door System will realize such operation by fewer staffs. Due to the above reasons, the Platform Screen Door System is becoming more popular in subway system recently.

This paper presents a case study of PSD(Platform Screen Door) system assurance based on EN50126 life-cycle stage. By applying this system assurance, the accidents related to urban light transit railway especially that caused casualties could be reduced tremendously. This case study contributes significantly to the reliability, availability, maintainability and safety of the PSD system. Request For Proposal (RFP) of a rail road operator in which required by RAMS is prepared in which to ensure all system assurance activity and safety assessment are compulsory. The step-by-step activities and related deliverables are used which include functional analysis, FMECA, hazard identification analysis, system hazard analysis, maintainability analysis, FRACAS, and finally verification and validation of the system.

The Platform Screen Door system(PSD) is scheduled to be installed on the platform of some subway stations in Seoul, Pusan, Kwang-Ju, Daejun and Daegu and all stations of Seoul Subway No 9. will equipped with PSD. On the other hand Seoul Metropolitan Rapid Speed(SMRT) that has operated the train automatically had finished the basic desic design and the execution drawing of PSD and installed successfully the PSD on the platforms in the Kimpo Airport station in Subway Line No 5. at dec. 2005. The exhibition operations of PSD has made the major contribution to build up the safe and optimum subway for the increasing customers. Nowadays PSD has operated on ATO sections and ATS sections. But in the case of closing the door manually in ATO sections, it would be delayed about 5 seconds in closing the door of PSD. Although the interface of PSD, train and the signal system is established automatically, we have to supplement technically on the interface between train, PSD and the ground signal interface equipments. Therefore I will center on the optimizing methods about the interfacing system between the train and the PSD, train and the signal system to overcome the above problems in this study.

이 글은 지하철 위험의 해결책으로 제시된 스크린도어를 대상으로 "기술적 해결"(technological fix)의 가능성과 한계를 검토하고 있다. 지하철 위험은 그 유형에 따라 모두 다섯 종류―"전철운행 사고", "역사 내 사고", "승강장 사고", "지하의 공간적 위험", "범죄 및 테러의 위험"―로 분류할 수 있는데, 가장 중요한 것은 궤도와 역사의 접촉면에 위치한 승강장에서 발생하는 승강장 사고이다. 스크린도어는 승강장 사고를 예방할 수 있는 효과적인 기술적 수단으로 여겨진다. 여기에는 사고를 기술적 수단을 통해 해결하려는 기술적 해결의 이데올로기가 강하게 작용한다. 신설되는 역이 아니라 기존 역의 승강장에 스크린도어를 설치하는 것이 세계적으로 유래를 찾기 힘든 경우라는 사실이 이를 잘 보여준다. 스크린도어는 현실적 수단으로서 가시적 효과를 낳았지만 예상치 못한 비가시적 위험을 가중시킨 측면도 없지 않다. 승강장 내부, 특히 출퇴근 환승역 승강장에서 화재가 발생했을 때, 스크린도어는 승객의 탈출로를 차단하는 "통곡의 벽"으로 돌변할 수 있다. 기술적 해결에 대한 지나친 기대와 의존은 금물이며, 그 한계에 대한 성찰이 요구되는 이유이다.

The most principal approach to improve indoor air quality(IAQ) of subway was to examine the fine particulate(PM-10) from the emission sources. Therefore, this study was carried on the investigation the fine particulate for comparison with the removal efficiency of PM-10 in divided the PSD(Platform Screen Door) and Non-PSD subway station from July, 2007 to May 2008. In the monitoring results, the range of PM-10 concentration of Non-PSD station was $44.6{\sim}116.5{\mu}g/m^3$ and the range of PM-10 concentration of PSD station was $23.9{\sim}81.1{\mu}g/m^3$. And then the range of PM-2.5 concentration of Non-PSD station was $17.4-56.6{\mu}g/m^3$, and then the range of PM-2.5 concentration of PSD station was $17.9{\sim}34.4{\mu}g/m^3$. In comparison with the results of the PSD and Non-PSD subway station, we found that the PM-10 removal efficiency of PSD was 30-40%. In conclusion, the PSD will be applied the effective facilities of decreasing PM-10 in subway station in Korea.

Platform Screen Door, PSD, is a device that seeks to prevent accidents with regards to falling off the platform and getting trapped between the trains, achieve improvements on the cleanliness of the air, address the accessibility issue of the disabled and the elderly and provide fresher environment on the platform in general. This is achieved by preventing health hazards and accidents from occurring through installation of fixed and moving doors between rail, tram and subway platforms and the railway. Domestic firms have achieved domestic production to a large degree in various Control Units including the Overall Control Unit and RF devices through investments in technology. Despite this, full domestic production of the core of the PSD system, Door Control Unit, DCU, is not yet achieved, having to install PSDs in a relatively short period of time. Currently, controllers with DC motors are developed for installation or one is faced with having to import foreign produced controllers. In this research, the control unit prototype using the BLDC motor was domestically produced. The performance of the control unit was rigorously tested through installation on Eun-Ha Rail on Wol-Mi Island.

PSD is automatically opened and closed when subway train arrive on the station. This system was designed to control electric automatic system. These doors will provide passenger safety, energy saving and a good environment in subway. The monitoring and control systems of PSD are configured so that they can be operated in automatic mode in connection with ATO through the composite control panel in the station control room. The objective of this paper is to obtain high reliability that is essential for monitoring and control systems of PSD. The power supply is based on protection circuit using DC power bridge from two UPS. Also, stable communication system consists of CAN communication line redundancy and RF cross protection algorithm. Monitoring state display results show the validity of the proposed high reliability monitoring and control systems of PSD.
