Title:
TIME SYNCHRONIZED COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/056609
Kind Code:
A1
Abstract:
A communication time period (TT) for operating state request information from a trap operating state management device (120) to a trap operating state provision device (110) requires ((number (N0) of inter-node communications along shortest communication pathway) x (unit inter-node communication time period (t0) required between nodes) = time period (TT1)) + ((unit rebroadcast processing time period (t1) required for one rebroadcast process) x (number (N-N0) of rebroadcast processes) = time period (TT2)). As a result, at the trap operating state provision device (110), synchronization processing initiation wait time period (TW) = (synchronization wait time period (Ta)) - (communication time period (TT) (=(TT1) + (TT2))) - (processing time period (TC1) at trap operating state provision device (110)), and when the synchronization processing initiation wait time period (TW) has elapsed, the time at a clock circuit (110j) is set to a synchronized time (T).
