| (54) | Signalling system |
| (57) Wayside equipment cannot acquire control information when an interlocking controller
is terminated. Therefore, signals inside the premises show stop indications, and operations
of trains stop. Field controllers of a signalling system realizes route control, the
field controllers having a transmission path for transmitting and receiving state
information between the field controllers constituting a route, having wayside equipment
control logic for realizing the route control of a train based on the received state
information, having first wayside equipment control logic used when communication
from the interlocking controller to the field controllers continues, having second
wayside equipment control logic for continuing the route control when the communication
from the interlocking controller to the field controllers is interrupted, and switching
the control logic from the first wayside equipment control logic to the second wayside
equipment control logic to continue the route control if the interrupt of communication
with the interlocking controller is detected.
