<p>PROBLEM TO BE SOLVED: To synchronize the times of respective processors with high precision irrelevantly to the styles of transmission lines constituting a decentralization system. SOLUTION: By this time synchronizing method, processors 11a, 12a, 21a, etc., constituting the decentralization system are grouped by processors connected to the same transmission lines and one processor in each group is determined as a time master. For example, the processor 11a in the group of a transmission line 10 and a processor 12a in the group of a transmission line 20 are dynamically determined. Further, an original time master for the reference time of the whole system is determined (e.g. processor 11a) and processors other than the time masters in the respective groups adjust their time with the times of the time masters in the groups in the order from the group including the original time master to adjacent groups to synchronize the times of all the processors in the system with the reference time.</p> |
