<p>PURPOSE:To accurately stop an electric rolling stock at a stop point, by computing in response to a program by receiving ground signals, by commanding deceleration corresponding to a deceleration pattern every a fixed distance and by shortening a fixed distance that deceleration is commanded every time receiving ground signals. CONSTITUTION:A distance between a 1st ground piece 2a and a virtual stop point as a L(m) unit, a distance between a 2nd ground piece 2b and the virtual stop point as 1/2 L(m) unit and a distance between a 3rd ground piece 2c and the virtual stop point and a distance between the virtual stop point and a true stop point as 1/4 L(m) unit are memorized to a memory 14 in binary digit. When a travelling electric rolling stock receives a signal of the 1st ground piece 2a, offering demand is emitted to a CPU 13 from an offering input circuit 12. When receiving offering, the CPU 13 deducts one of the distance in L(m) unit memorized in the memory 14 from the 1st ground piece 2a by an answering routine, and the speed information of a counter 11 is input through an address data bus 16. Thus, the CPU 13 puts out a fixed brake step command to an output amplifying circuit 15.</p> |
