로프타입 상하개폐식 승강장 안전문의 개폐제어 알고리즘에 관한 연구

Most trains operated in the urban rail network in Korea have the same or similar attributes in terms of their physical dimensions per unit vehicle. By comparison, those in Japan and the United States compose of different features including lengths or various numbers of doors per unit vehicle. Hence, the existing PSD (Platform Screen Door) is not generally applicable to different types of trains due, for example, to different door positions by various train types. RPSD (Rope-type Platform Safe Door) has been developed in response to such inconsistencies in train features in order to accommodate different types of trains regardless of the length, or the locations of the doors. Since RPSD should open only when the train doors open, one of the most critical features of RPSD is the detection on opening and closing movement of the train doors. Therefore, the objective of this study is to develop an operational algorithm to minimize the detection error on opening and closing movement of the train doors. For this purpose, this study assessed a variety of alternative algorithms with respect to various train types to find the safest and optimal system of operation.
