POSITION DETECTING APPARATUS FOR MAGNETIC LEVITATION TRAIN USING OF A MAGNETIC BAR

The present invention relates to a train position detecting device for a magnetic levitation train using a magnetic bar which can be installed at low costs and ensure high accuracy. A magnetic bar having an N pole and an S pole is disposed along a railroad, and the magnetic bar is counted through a magnetic reader installed on a vehicle to detect a relative position. A proceeding direction thereof can be grasped according to a comparison of detection waveforms. When the train position detecting device of the present invention is applied, a device for detecting a train position can be easily and simply constructed, thereby ensuring economical feasibility. A malfunction rate is low, thereby ensuring easy maintenance. Forward driving and backward driving of a train can be sensed, thereby reducing a rate of occurrence of driving-related safety accidents.
