Abstract

The invention is applicable in the technical field of network communication, and provides a realizing device of accurate time synchronization protocol, the device comprises a system initialization unit, initializing the realizing device of PTP (precision time protocol), preparing for running of PTP(precision time protocol); a human-computer interaction unit, providing one or more interactive interfaces, providing interact between users and the realizing device of the PTP(precision time protocol); a protocol engine unit, running PTP(precision time protocol); a hardware communication unit, stamping time for all PTP(precision time protocol) messages of engine unit organization of the protocol , transmitting the PTP(precision time protocol) messages with stamp between the master clock device and the vice clock device. The invention of realizing device of PTP(precision time protocol) runs the PTP(precision time protocol) in the network, realizing high-precision synchronization of the network clock, and solving all kinds of problems caused by error of clock synchronization or asynchronization in the current industrial control.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a device for realizing a precise time synchronization protocol. Background technique [0002] In the current industrial control process, a series of problems have been caused to the industrial control due to the difference between the clocks in the industrial control network or the large synchronization error. In order to solve the synchronization problem of each clock in the network. The prior art provides various protocols that can support network clock synchronization, such as Network Time Protocol (Network Time Protocol, NTP), Simple Network Time Protocol (Simple Network Time Protocol, SNTP) and so on. However, the common disadvantage of these protocols that support network clock synchronization is that the clock synchronization accuracy is not high, generally at the millisecond level, which cannot well meet the application requirements of modern industrial control, such...
