Title:
CENTRALIZED 1588 IMPLEMENTATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/056921
Kind Code:
A1
Abstract:
A centralized 1588 implementation system and method, relating to the field of 1588 time synchronization. The system comprises a master clock device and a slave clock device, each device comprising a master control panel and a line panel, the master control panel and the line panel each comprising a time synchronization module, the master control panel further comprising a local time module. The time synchronization module of the master control panel completes the sending and receiving of a 1588 message, and calculates the difference according to the collected data and completes time synchronization adjustment of the device; The local time module of the master control panel is configured to output a 1PPS+TOD signal to the time synchronization module of the line panel for synchronization, and is further configured to complete the normal forwarding and time stamping of the 1588 message and correct forwarding delay of the message within the device. The time synchronization module of the line panel completes the normal forwarding and time stamping of the 1588 message and corrects forwarding delay of the message within the device. The present invention ensures the convergence of time synchronization between devices implemented in a centralized manner in the case of interaction of messages at any rate.
