Abstract

The invention discloses a real-time adaptive convergence estimation system for time synchronization. The real-time adaptive convergence estimation system comprises a synchronization error estimation unit, a synchronization error feature estimation model and a real-time convergence detection model. The method can be applied to a distributed system or a wireless network with a time synchronization requirement, the method is integrated into a time synchronization algorithm used by an application object, and the synchronization error convergence probability is further calculated by utilizing timemigration estimation obtained by the time synchronization algorithm. The synchronization error convergence probability obtained by the method can be used as a basis for determining the system time synchronization precision and convergence state by other applications or a time synchronization algorithm.

Description

technical field [0001] The invention relates to the technical field of time synchronization, in particular to a real-time self-adaptive convergence estimation system for time synchronization. Background technique [0002] According to published papers at home and abroad, relevant patent information, and related protocols or standards such as NTP (Network Time Protocol), IEEE standard 1588v2, WIA-PA, ISA100.11a and WirelessHART, the existing technologies for large-scale wireless network time synchronization are mainly Concentrate on time information exchange, parameter estimation and implementation schemes of time synchronization algorithms. However, there is no specific research on the online estimation of network time synchronization convergence state. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, a real-time self-adaptive convergence estimation system for time synchronization provided by the present invention solves the ...
