DETECTING APPARATUS OF TRAIN'S POSITION USING OF A RESONANT CIRCUIT

The present invention relates to an apparatus of detecting the position of a train by using a resonant circuit. The purpose of the present invention is to provide an apparatus of detecting the position of a train which includes an input sensor having LC resonant circuits and an output sensor having LC resonant circuits. The input sensor and the output sensor are separated by the normal length of the train. It detects the change of current when each train′s wheel passes by and can accurately detect whether the train passes by and how many trains pass by. According to the present invention, provided is a cheap detecting apparatus using an LC resonant circuit. Also, it can accurately detect the change of current so that economic feasibility and accuracy are improved.
