<p>PURPOSE:To keep the position of stoppage constant regardless of the speed of a train by changing the starting timing of brake application in response to the speed of the train. CONSTITUTION:When a train reaches a point A, a point A detecting command (a) is outputted, and a point A relay 21 is turned OFF after a time T passes. When the train reaches a point B, a point B detecting command (b) is outputted, and a point B relay 22 is turned OFF. When the train runs at high speed and the point B relay 22 is turned OFF before the point A relay 21 is turned OFF, a brake relay 20 is turned OFF, and a brake command (e) is outputted. When the train runs at low speed and the point B relay 22 is turned OFF, a speed relay 24 and the brake relay 20 are kept under an ON state because the point A relay 21 is turned OFF. When the train reaches a point C and a point C relay 23 is turned OFF,,the speed relay 24 and the brake relay 20 are turned OFF, and the brake command (e) is outputted.</p> |
