Abstract

The invention discloses a time data processing method, device and system. The method comprises the steps of receiving a first time message and a second time message sent by a server, wherein a time interval is reserved between the sending time of the first time message and the sending time of the second time message; confirming first time of the first time message arriving a terminal and second time of the second time message arriving the terminal; sending a delay request message to the server and receiving a delay response message fed back by the server and corresponding to the delay request message; obtaining third time of the delay response message arriving the terminal and fourth of the delay request message arriving the terminal; confirming the delay time and drift compensation amount according to the first time, the second time, the third time and the fourth time; using the delay time and drift compensation amount to perform time synchronization processing on the terminal. By adopting the time data processing scheme based on IEC61850 adopting the time data processing method, device and system, the problem of low time synchronization accuracy of a time synchronization system in the prior art is solved, and the effect of improving the time synchronization accuracy is achieved.

Description

Technical field [0001] The present invention relates to the field of clock monitoring, in particular to a time data processing method, device and system. Background technique [0002] At present, the equipment time synchronization system of industrial automation generally adopts the method of combining direct time synchronization and network time synchronization. Various IEDs (Intelligent Electronic Devices) used in the industrial automation industry use digital processing technology. The internal crystal oscillator circuit can be accompanied by time stamp information when outputting information. However, this method is in practical applications because of different IEDs will have clock delays, and the time accumulation of different IEDs will increase the time error. The traditional time synchronization method is to first synchronize the time of the main IEDs, and then synchronize the time of the sub-IEDs in the form of time messages. In actual applications, time synchronization...
