TIME SYNCHRONIZATION PROCESSING SYSTEM, TIME INFORMATION DISTRIBUTOR, TIME SYNCHRONIZATION PROCESSOR, TIME INFORMATION DISTRIBUTION PROGRAM, AND TIME SYNCHRONIZATION PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform accurate and simple time synchronization processing in a device connected to a radio network.

SOLUTION: A time information distributor 10 of a master 1 receives a reference time signal that synchronizes with an accurate clock device by an antenna 3, generates a packet of time synchronization which is a time packet describing a transmission completion time of the preceding time packet in an information storage area, and accurately broadcasts the time packet from an antenna 4 for a radio LAN to a slave 2 at a fixed interval (just one second). The slave 2 receives a time packet signal from an antenna 5 for a radio LAN, and a time synchronization processor 30 uses a relation between a reception completion time of the received time packet and a transmission completion time of the preceding packet in the time packet to perform synchronization processing for synchronizing the time of the slave 2 with that of the master 1.
