Step C1, the PLC in yard station control system starts break-make monitoring order, and the operator workstation in station control system exists
After receiving the PLC break-make monitoring signals in yard station control system, by the clock of the operator workstation in station control system
The PLC into yard station control system is sent in seconds, and the PLC in yard station control system is received in station control system
Operator workstation clock after, while starting the timer of 20 seconds；
Step C2, the PLC in yard station control system gathers the clock source signals of the 1st second and the 10th second, and compares the 1st second and
Whether the clock source signals value for being collected for 10 seconds is consistent：
If collect the 1st second of the PLC in yard station control system and the 10th second clock source signals value are inconsistent, communication is being represented just
Often, after 13 seconds, the PLC in yard station control system proceeds step C2；
If, the expression communication event consistent with the 10th second clock source signals value in the 1st second that the PLC in yard station control system is collected
Barrier, carries out step C3；
Step 3, trigger a communication failure counter, count once, after 20 seconds, the PLC in yard station control system continue into
Row step C2；
Meanwhile, whether the PLC in yard station control system judges communication failure counter more than 2, and judges the 1st second and the 10th second
Whether the clock source signals value for being collected is consistent：
If after the PLC in yard station control system is detected 1 time or 2 communication failures communicate, in yard station control system
The clock source signals value that PLC is collected is inconsistent, then communication failure counter automatically resets；
If the PLC in yard station control system detects continuous 3 communication failures, the PLC in yard station control system is collected
Clock source signals value it is consistent, then show that a communication disruption is reported to the police on the operator workstation in yard station control system,
Determine whether communication recovers simultaneously, step C4 is carried out if after communication recovery is normal, conversely, communication disruption alarm count device is counted
Continue to determine whether communication recovers after plus one；
Step C4, communication disruption alarm count device and communication failure counter automatically reset, while in yard station control system
PLC issues the order stopped with the operator workstation communication disruption in station control system.
