Abstract:
PURPOSE: An interface station system between a tube railway and an atmospheric railway of a tube railway system is provided to reduce the construction costs for a tube railway system without reduction of the travel performance. CONSTITUTION: An interface station system between a tube railway and an atmospheric railway of a tube railway system comprises a station tube railway system and a control unit(80). The station tube railway system includes a station tube railway which is formed at the boundary between the atmospheric railway and the tube railway, atmosphere and vacuum side vacuum blocking screen devices(30,40) which are installed in the entrance of the station tube railway to block the air of the atmospheric railway, the tube railway, and the station tube railway, a vacuum pump(50) which creates vacuum in the station tube railway, a vacuum breaking valve(60) which breaks the inner vacuum of the station tube railway to form an atmosphere state, and a pressure sensing unit(70) which senses the inner pressure of the station tube railway. The control unit regulates the internal pressure of the station tube railway and controls the vacuum blocking screen devices according to the travel direction of a train.

본 발명은 철도차량의 대차 저면에 선형유도전동기의 1차측 전기자를 취부할 때, 1차측 전기자의 상하 변위를 조절하는 변위조절기가 받는 1차측 전기자의 하중을 감소시킬 수 있는 림·대차 고정부를 구비함과 아울러, 1차측 전기자의 전방 위치에 설치된 공극센서를 통해 실시간으로 감지되는 1차측 전기자와 2차측 회전자 사이의 공극의 크기정보를 이용하여 변위조절기를 제어함에 따라 노면의 변화에 대응하여 공극의 크기를 일정하게 유지하거나 최소화함으로써 추진력의 효율을 극대화할 수 있도록 된 철도차량용 선형유도전동기의 공극제어 시스템에 관한 것이다. 선형유도전동기, 공극, 전기자, 회전자, 공극센서, 변위조절기, 림·대차 고정부, 스프링.
Abstract:
An aperture control system of linear induction motor for a train is provided to stabilize the operation of train by regularly maintaining the aperture control system of linear induction motor. A rotor is installed on the surface between the rails. An armature is installed at the bottom surface of the carriage. An aperture control part(500) is made of an air gap sensor(400), a controller(450) and a displacement controller(100). The rotor is made of the aluminum plate. The displacement controller controls the air gap between the armature and the rotor. A rim fixing unit and a carriage fixing unit(200,300) connects the armature to the carriage. The load of armature is decreased. The displacement controller, the linear induction motor and the carriage fixing unit are equipped in the back side of armature.
Abstract:
A system for evaluating power efficiency of a streetcar track is provided to measure dynamic uplift amount and vibration generated in a streetcar track in passing pantograph by using a laser and a high speed camera. A system for evaluating power efficiency of a streetcar track includes a high speed camera(30), a laser(40), and an image processing device(20). When a pantograph(15) of a streetcar(10) passes through a measuring point on a streetcar track(50), the high speed camera obtains an image of the streetcar track by high speed photographing. The laser is a light source of the high speed camera. The laser is irradiated on the streetcar track of the measuring point. The image processing device stores and outputs a photographing data of the high speed camera. The image processing device measures displacement of the streetcar track by analyzing the obtained image.
