<p>PURPOSE:To improve the accuracy of stoppage by changing over control to one according to a nonlinear type notch output pattern determined by a travelling distance from one according to a stoppage pattern determined by ground signals when specified ground signals are received before a predetermined distance from a stoppage target point. CONSTITUTION:A pattern generator 6 outputs the stoppage pattern fp in response to the ground signals a, and a proportional controller 7 compares the stoppage pattern fp and speed signals, and outputs a brake notch. When the specified point signals b are received before the stoppage target point, a control changeover logic circuit 3 is set, and the output of the proportional controller 7 is interrupted. On the other hand, a distance integrator 9 counts speed pulses fv, and a train speed detector 8 detects train speed by stages. A V-S notch matrix circuit 10 outputs a brake notch corresponding to the output of the distance integrator 9 and the train speed detector 8.</p> |
