Time synchronization method, device and system and a storage medium

Abstract

The invention provides a time synchronization method, device and system and a storage medium. The time synchronization system comprises a first part and a second part, the first part and the second part are mechanically coupled, the first part and the second part can move relatively, and the first part and the second part are in wireless communication connection. The method comprises the steps that the second part receives first time axis information and first motion parameters sent by the first part, wherein the first motion parameters correspond to the first time axis information and are used for representing the motion relation between the first part and the second part; the second part determines second time axis information corresponding to the first motion parameter in a local secondtime axis; and the second part adjusts the second time axis according to the first time axis information and the second time axis information, so that the second time axis is synchronized with the first time axis. According to the method, the influence of wireless communication delay on time axis synchronization can be relieved to a certain extent, and the synchronization efficiency is improved.

Description

Technical field [0001] The present invention relates to data processing technology, in particular to a time synchronization method, device and system, and storage medium. Background technique [0002] There are generally at least two modules in a large electronic system. Each module performs work and data processing according to its own clock system. Therefore, if the clocks between the modules in the same system cannot be synchronized, the time may be out of synchronization. This creates a security risk. [0003] At present, for two independent modules in the same system, if the two have relative motion, they can only rely on wireless communication for data synchronization. However, due to the large delay in wireless communication, the prior art usually The delay is estimated multiple times and the average value is taken as the communication delay between the two independent modules, so that the time between the two independent modules is synchronized based on the communication d...
