TLDR
In this article, a clock synchronization method, clock synchronization equipment, and clock synchronization system is presented to realize the uniformity of message round trip links between the master clock equipment and the slave clock equipment, which ensures the symmetry of uplink delay and downlink delay.Abstract:
The invention provides a clock synchronization method, clock synchronization equipment and a clock synchronization system. The method comprises the following steps of: in a first transmission mode, generating a first receiving timestamp by using a first link and acquiring a first transmitting timestamp of master clock equipment; in a second transmission mode, generating a second transmitting timestamp by using the first link and acquiring a second receiving timestamp of the master clock equipment; and according to the first receiving timestamp, the first transmitting timestamp, the second transmitting timestamp and the second receiving timestamp, acquiring a time deviation with the master clock equipment; and realizing clock synchronization with the master clock equipment through the time deviation. The embodiment of the invention provides slave clock equipment and the master clock equipment. The embodiment of the invention also provides the clock synchronization system. The method, the equipment and the system realize the uniformity of message round trip links between the master clock equipment and the slave clock equipment, and ensure the symmetry of uplink delay and downlink delay.read more
