Abstract:
PURPOSE: A movable station is provided to enable the inexpensive construction of an underground or ground station which moves underground or overground based on the arrival time of trains while passengers are waiting for the trains at a station on a street. CONSTITUTION: A movable station comprises an outside structure, a station structure, an elevating unit (115), a vehicle access door device (130), a ceiling opening and closing device (140), a passenger access door device (150), and a control unit. The outside structure is fixed on the ground with a bus station. The station structure is equipped inside the outside structure to elevate a train to an underground platform area in which the train goes up or down. The elevating unit elevates the station structure. The vehicle access door device includes a screen door (132) which is opened or closed to allow passengers to get on or off a train. The ceiling opening and closing device is formed on the ceiling of the station structure and is equipped with an opening and closing plate (142). The passenger access door device is equipped with a passenger access door (152) which allows the access of passengers to the station structure. The control unit controls the operation of the elevating unit, the vehicle access door device, the ceiling opening and closing device, and the passenger access door device.

본 발명은 지하철 차량의 기관실과 객실간의 브이디에스엘 전송방식을 이용한 실시간 객실감시용 데이터전송 시스템에 관한 것으로; 지하철 객실에 구비되어 실시간으로 고화질의 객실 감시를 위한 영상을 촬영하는 카메라와, 상기 카메라에서 촬영된 객실감시용 영상데이터를 전송하는 VDSL모뎀과, 지하철 기관실에 구비되어 상기 VDSL모뎀으로부터 객실감시용 영상데이터를 수신받는 VDSL집중장비로 구성되는 것을 특징으로 한다. 본 발명에 따르면, 열차에 설치된 기존의 인터폰 전화망을 이용하여 VDSL(very high-data rate digital subscriber line)망을 구축함으로써 추가적인 케이블의 설치 없이도 열차의 객실에서 기관실로의 객실감시 영상의 전송뿐 아니라 기존의 객실광고 방송, 인터폰 및 비상호출 등과의 연동운영도 가능하다. 또한, 본 발명은 객실과 기관실 통합 양방향의 초고속 데이터 통신망을 제공하면서도 추가적인 케이블의 설치가 필요 없어 통신망의 구축을 위한 비용의 절감 효과도 있다.
Abstract:
PURPOSE: A railway vehicle reliability calculating method through malfunction enumeration of a reliability path is provided to calculate reliability through malfunction enumeration of a reliability path. CONSTITUTION: A reliability relation between a railway vehicle system and a lower component is configured in an RBD(Reliability Block Diagram)(S10). The RBD is expressed in a matrix by using an adjacent matrix(S20). A reliability path matrix is configured in all paths of the RBD(S30). A malfunction enumeration matrix of the lower component is configured through the reliability path matrix(S40). A system reliability is calculated by adding the probability of a normal system to a malfunction matrix(S60).

Abstract:
PURPOSE: A sound absorbing plate for the railway concrete roadbed, a sound absorbing construction method using the same and a sound absorbing structure are provided to reduce the repair and maintenance cost of the sound absorbing plate and railway concrete roadbed by easily installing and removing an absorbing plate. CONSTITUTION: A sound absorbing plate for the railway concrete roadbed comprises a plurality of convex portions(10) and a plurality of concave portions(11). The convex portion is formed in the longitudinal direction one side of the sound absorbing plate into the traverse direction. The convex portion is projected with the thickness smaller than the total thickness of the sound absorbing plate from the top of one side. The concave portion is formed in the longitudinal direction other side face of the sound absorbing plate.
Abstract:
PURPOSE: A roaming realizing method between radio base stations in a high mobile body is provided to smoothly process roaming between radio stations of mobile wireless transceivers of high mobile body. CONSTITUTION: A directional antenna is installed to a reserve direction and the process direction of a mobile wireless transceiver of the high mobile body. Each ground radio transceiver transmits receiving sensitivity information about a radio receiving signal which is received through the directional antenna to the directional antenna(S2). The wireless radio station analyzes the receiving sensitivity information which is collected from each ground wireless transceiver(S3). The ground radio station realizes roaming with a frequency in which the instant receiving sensitivity rate has a maximum value(S5).
