摘要

Node( 104 )Including N number of time regeneration unit(105 to 107)Each and every N number of host node(101 to 103)Between propagation delay calculate each host node(101 to 103)With( 104 )Time slave node and regenerated each host node(101 to( 104 )0,Time comparing unit( 104 )Comparison result between 1 calculates each independently of one another in each host node,( 104 )2 to( 104 )3,It is reproduced with every N number of time regeneration unit( 104 )4 to( 104 )5,Reference time keeps by from node( 104 )6,With( 104 )7 that chronometry unit,It is weighted by each corrected value of calculating to calculate comparison result respectively,Until comparing unit (104) 8 determines that the node (104) 9 of reference time carries out statistical disposition based on propagation delay, by utilizing corrected value. Utilize this structure, it is possible to improve the slave node of the synchronization time of preci-sion and accuracy, it is at low cost.
