The TASC control device 4 calculates the train speed 12 based on the speed signal 6 from the speed generator 5, and when the train approaches the stop station and passes through the first ground child P1, the point detection device 1 uses the Detected from T
An ASC point signal 3 is sent to the TASC controller 4. T
The ASC controller 4 receives this and generates a stop control pattern 13 shown in FIG. 7, and applies a brake so that the train speed 12 follows the stop control pattern 13, that is, the train can stop at the fixed position stop point 10. Increase or decrease command 7. Note that the first ground child P1 serving as a trigger for starting the generation of the stop control pattern 13 is normally provided with redundancy by adding two first ground child auxiliary P1's in order to increase its reliability.

The stop control pattern 13 is reduced in accordance with the moving distance obtained by integrating the speed signal 6. At this time, the moving distance caused by the deviation between the wheel diameter and the actual wheel diameter preset on the device side. In order to correct the error of the train, the second and third ground members P2 and P3 are installed immediately before the fixed position stop point 10, and when a signal from this is detected, the train position is corrected based on the known data, and fine adjustment is performed. Make adjustments.
