Embodiment
In order to solve the technical problem proposed in background technology, the inventor of the disclosure to existing distributed apparatus when
Between synchronous method analyzed.In the method for synchronizing time of existing distributed apparatus, service board passes through CPU message between plate
Communication mode, the time difference DeltaT being calculated on service board based on PTP protocol, send to main control veneer
CPU.Main control veneer CPU adjusts global clock module according to time difference DeltaT, then passes through bus B US by global clock module
Interface synchronization gives the clock module of each service board.In this method, service board calculates acquisition time difference DeltaT can not
Enter row clock regulation at once, and service board needs to obtain when can just carry out next time after the setting return information of main control veneer
Between it is synchronous, cause time synchronized efficiency low.
As shown in Fig. 2 the time synchronized of distributed apparatus is completed by following step in the prior art：
It is configured with from the CPU of the service board of port and the time difference is determined according to the PTP messages received from upstream equipment, passes through
CPU message communicatings mode between plate, be sent to the CPU of main control veneer the time difference.Main control veneer CPU adjusts according to the time difference
Global clock module Clock Card on this plate, then other business are synchronized to by clock synchronous bus by Clock Card modules
Veneer.
Between the plate of the above method in CPU message communicatings mode, being configured with from the service board of port needs to obtain main control
Time synchronized next time can be just carried out after the setting return information of veneer.And main control veneer sets Clock Card clocks, by
In the realization mechanism of clock chip, after adjusted value will not come into force, it is necessary to wait next second to come into force, other industry can be just synchronized to
The clock module of business veneer.Even if so be configured with from the service board of port when the setting return information of main control veneer,
But this plate clock might not adjusted completion, for the sake of assurance, generally requiring wait could be carried out next time for more than two seconds
Time synchronized, time synchronized is less efficient, can not accomplish the multiple time synchronized of progress per second.
Adjust the time of the clock module of itself in real time after the time difference is obtained if configured with the service board from port,
And the time after adjustment is sent to main control veneer through clock synchronous bus by clock module；Main control veneer is through clock
Synchronous bus sends the time after adjustment to the clock module of other service boards.Substituted by clock synchronous bus existing
Plate between CPU message communicating modes, the efficiency of distributed apparatus time synchronized can be improved.
