| Abstract: | Clock drift and undetermined delay of transmission are the serious problems in the distributed system,which will de-teriorate the precision of clock synchronization.To improve the precision,this paper analyzes the mechanism of synchronization and designs the hardware structure of the slave clock node about IEEE 1588 precise clock synchronization protocol,proposes the precise clock synchronization algorithm,which combined data filter and PI control based on PLL. |
