2. Description of the Related Art In recent years, an automatic train operation method has been adopted which automatically controls operation operations such as speed control and stop of a train. This operating method is a method of always knowing the train speed, position, operating time, preceding train and track status, controlling the train speed while comparing with the standard operation diagram to operate the train, and stop at a predetermined position.

As a method of automatically stopping the train at a fixed position, a curve corresponding to a deceleration curve that the train follows when a brake is applied to the train on a distance and speed plane with the stop position as a reference. The braking device is controlled so as to set the speed and decelerate along this curve.

However, it is difficult to keep the braking force of an actual train with a different train set constant, and there is considerable variation. Therefore, even if control is performed so as to decelerate along a curve corresponding to the deceleration curve, There is an error from the deceleration curve that the train follows. In order to correct this, for example, a coil row is arranged at regular intervals before the stop position, and a signal corresponding to a deceleration curve for stopping the train at the fixed position is set for each coil, and the braking device is set. Are in control.

The present invention has been made in response to such a demand, and an object thereof is to obtain a fixed position stop control device capable of controlling the stop position of a train with a simple structure and with higher accuracy.
