  • To prevent safety accidents such as injury or death from falling by blocking platforms from trains, the Seoul Metropolitan Subway Corp. have gradually installed screen doors in platforms of 115 subway stations in Seoul on lines 1, 2, 3, and 4. Installation in nine areas among those has been completed and screen doors are being operated as a model operation. Traffic signs should be clear for users. The essential functions of signs should be fully investigated from the aspect of user as well as the visual beauty and recognition. Signs should be able to provide users with information regarding location, position, directions, etc. Particularly, safety and convenient signs should be visually and sensually correlated. However, the entire screen doors in platforms installed in line 2 subway in Seoul are used for commercial advertisement, consequently, the functions and roles as public signs are not fulfilled aggravating inconvenience for users. In this study, cases have been studied to investigate requirements for user-oriented sign system in platform and public sign space to fulfill the functions of sign system in platform. Using an anthropometry approach, the study aimed to obtain the space to install the sign system and to systemize necessary and sufficient conditions for user-oriented system for platform in which screen doors have been installed using. The study suggests fundamental information to obtain the space of public sign system on the entire screen door.

  • 본 연구에서는 열차와 지하철 역사 형상긴의 유통 흐름에 대한 상호작용을 고려하여 승강장 스크린도어(PSD)봐 비정상 풍압해석을 수행하였다. PSD의 주목적은 열차가 역사 안으로 진입할 때, 인명사고를 예방하고 풍압, 오염된 분진, 소음 등을 차단하는데 있다. PSD에 대한 비정상 풍압수준을 정확하게 예측하기 위하여 이동격자법을 활용한 전산유체역학 기법이 적용되었다. 개방형 및 밀폐형 역사가 고려되었으며, 열차가 역사를 통과하는 경우와 역사에서 멈추는 경우에 대한 풍압 수준을 상호 비교하였다.

  • A study on fire phenomena in a subway transit mass station has been carried out as a part of disaster prevention plan at the subway station. The ventilation facilities installed in both the platform and the trackway are designed to convert into a smoke exhaust system in emergency situation, creating such an environment as necessary for evacuation. 3 dimensional Numerical Simulations based on the CFD are carried out using a simulation tool, Fire Dynamic Simulator. Additionally, four different vent modes are made and performances are compared with the original design mode and each other to find better operation of vents at both the platform and the trackway in case of fire. From the result, an vent operational characteristics under the condition of installed PSD is clarified for the effective smoke and heat removal from the platform area compared with non installed PSD.

  • The ascent and descent market screen door (PSD-Platform Screen Door) between the electromotive car which is in the process of operating from the subway ascent and descent market and the passenger it is an immediacy and crisis as the system which it intercepts currently the inside and outside of the country of course signal system automatic operation signal system (ATO) establishment is operated from the segment. Manual operation signal system (the ATS and the ATC) almost it is a condition which is wholly lacking from the segment. This year from second half of the year 2 line manual operation signal system (ATS). It established the shutting tightly elder brother and the railing elder brother in PSD system in segment 12 reverses and the death accident due to the passenger hurt accident which occurs from the subway. It prevented an energy curtailment in the same time when it raises air cooling efficiency, It gathered it restricted the underground space which is comfortable in the use citizen and and and service it did interface the electromotive car and PSD entrance and exit literature course from the manual operation segment to sleep technically optimizationt. It researched a minute dust diffusion.

  • In the present study, the analysis on heat and fluid flow in subway station platform is carried out by considering the pressure drop between screen doors and stair passages. To investigate the effect on the characteristics of heat and fluid flow of pressure drop, Numerical simulation is applied. The present results show a better cooling condition, in the case of without pressure drop.

  • 본 논문에서는 승객 보호용으로 지하철 역사에 설치된 PSD(승강장 스크린 도어)의 상부 헤더박스 내에 부착되어 개폐용 유리문을 지지하는 알루미늄 구동(레일)부재에 대한 구조해석과 최적설계를 수행하였다. 구동부재의 볼트 체결부에 대한 엄밀한 구조해석을 위하여 물리적 현상과 일치하도록 상세 유한요소 모델링하여 해석의 정확도를 높였다. 또한 유리문이 구동부재에 걸려 있으면서 개폐될 때 발생하는 하중의 이동상태를 고려한 구조해석 결과, 설계 목표치인 내구 수명 20년이 만족되었다. 구동부재 단면의 단면 길이를 설계변수로 하고 설계제약조건(응력의 최소화, 중량의 감소)에 만족할 수 있도록 반응표면법을 적용한 최적화를 수행하여 15%의 감량 결과를 도출하였다.

  • 기존의 승강장 안전문은 철도 차량의 출입문과 승강장 안전문이 1:1로 매칭이 되어야만 사용이 가능하기 때문에 다양한 열차가 정차하는 승강장에는 적용이 매우 어렵다. 이러한 문제를 해결하기 위해 제시된 승강장 안전문이 로프타입 상하개폐식 승강장 안전문(Rope type Platform Safe Door : RPSD)이다. 로프타입 상하개폐식 승강장 안전문은 승강장 안전문이 위에서 아래로 닫히고 승강장 안전문의 상하 이동을 위한 기둥은 20~40m 간격으로 설치되기 때문에 열차의 길이 및 출입문 위치, 출입문 개수와 상관없이 다양한 열차가 혼용하여 사용할 수 있도록 설계되었다. 본 논문에서는 다양한 열차가 정차하는 영등포역 일반열차 승강장에 기존 PSD 및 RPSD의 적용이 가능한지를 시뮬레이션을 통해 검토하였다. 검토결과 기존의 PSD는 시공, 안전, 비용상 문제가 발생할 것으로 파악되었으나, RPSD의 경우에는 적용에 큰 문제가 없는 것으로 나타났다.

  • Platform Screen Door(PSD) has been installed and operated at seoul subway line $1\sim4$ in the manual train operation mode(ATS/ATC) by SeoulMetro since 2005. SeoulMetro uses the wireless (RF) communication system and the train door detection system for the link between the train and PSD doors opening/closing motion in the manual train operation mode. For the convenience and safety of passengers, the train doors and the PSD doors opening/closing shall be synchronized as much as possible. In ATO(Automatic Train Operation) mode which provides the interface between train control system and PSD system, ATO signaling system makes the train doors and PSD doors open/close command signals systematically, so PSD doors can be opened/closed almost simultaneously with the train doors. But, in the manual train control(ATS/ATC) mode, PSD system needs to detect the train doors open/close operation and make PSD open/close command signals to actuate PSD doors. These PSD open/close commanding process cause time delay of PSD doors opening/closing motion in response to the train doors opening/closing motion. Sometimes the response delay time can be over 1 second, which is not proper to operate PSD, and need to be reduced This paper presents the reduction method of the PSD response delay time to improve the convenience and safety of passengers.

  • Metro serves more than a basic function of transporting passengers between short distances but became a crucial part of civic culture due to the fact that citizens demand various facilities for better life style. Therefore, domestic metro cuts off train noise and air dust, provides pleasant platform surroundings by offering effective HVAC, and establishes PSD (Platform Screen Door) system to prevent falls into train tracks. To control and interlock EMU Door and PSD to avoid passenger complaint and revenue service obstructions, stability and reliability of on-board & wayside equipment are required foremost and each line needs to build optimum interface between on-board & wayside equipment. To control PSD, we would like to introduce examples of Busan Metro(BTC : Busan Transportation Corporation) which already utilizes interface between on-board & wayside equipment in various ways and consider optimum interface between on-board & wayside equipment in future PSD system.
