Abstract

본 발명은 전자석의 흡인력으로 부상상태를 유지하는 시스템, 예컨데 자기 부상 열차 또는 산업용 이송장치등에 적용되는 자기 부상 센서 신호 선택 장치에 관한 것으로, 이는 단일 거리 감지 센서의 구성으로 레일과 레일이 연결되는 연결부를 거리측정 센서가 지날 경우마다 거리 감지 센서의 대응면에는 레일이 존재하지 않기 때문에 이상 펄스가 발생하게 되고, 이 이상펄스가 검출될때 마다 부상 제어기에서는 입력 파형에 대응하는 명령을 초퍼에 전달하여 전자석의 부상 위치를 변화시키게 되어 이동체가 전자석의 불필요한 운동에 따라 상,하 운동되므로서 자기 부상 열차의 경우 승객에게 불쾌한 승차감을 제공할 뿐만 아니라, 정상적인 부상 상태를 유지 할수가 없는 종래 기술의 문제점을 해소하고자 하는 것이다.The present invention relates to a magnetic levitation sensor signal selection device applied to a system for maintaining a floating state by the suction force of the electromagnet, for example, a magnetic levitation train or an industrial transport device, which is connected to the rail and the rail in the configuration of a single distance sensor Whenever the distance measuring sensor passes, an abnormal pulse occurs because there is no rail on the corresponding surface of the distance sensor. Whenever this abnormal pulse is detected, the floating controller transmits a command corresponding to the input waveform to the chopper. Since the moving body is moved up and down according to unnecessary movement of the electromagnet, not only the unpleasant ride feeling is provided to the passenger in the case of the magnetically injured train, but also the problem of the prior art which cannot maintain a normal injury state is solved. I would like to.

이에 따른 본 발명은 기존의 자기 부상 시스템에 전자석의 거리를 검출하는 거리 감지 센서를 복수개로 구상하고 이 복수의 센서 신호중 올바른 신호를 교호적으로 선택 처리하는 센서 신호 선택부를 구비하여 두 개의 검출신호중 적은 값을 선택적으로 출력하도록 하므로서 부상체 이동시 센서 대응면의 부재에 따라 부상의 불안전 해소 내지는 추락사고를 방지할 수가 있는 동시 자기 부상 열차에 적용할 시에는 레일의 불연속 구간에 따른 흔들림을 방지하므로 승차감 향상에 크게 기여할 수가 있고, 아울러 차량의 안전성에도 지대한 성과가 있게 된다.Accordingly, the present invention provides a plurality of distance sensing sensors for detecting the distance of the electromagnet in the existing magnetic levitation system and includes a sensor signal selector for alternately selecting and processing correct signals among the plurality of sensor signals. By selectively outputting the value, it is possible to improve the riding comfort by preventing the shaking due to the discontinuity of the rail when applied to the simultaneous magnetic levitation train that can prevent instability or fall accidents of injuries due to the absence of the sensor's corresponding surface when moving the injured body. Can contribute greatly to the safety of the vehicle, and also has a great effect on the safety of the vehicle.
