Abstract

The present invention provides a time synchronization processing method and device, wherein the method includes: acquiring the number of child nodes recorded in a node list; establishing a target tree for the child nodes according to the number of the child nodes and the principle of minimum synchronization time In the case where the number of layers of the target tree-shaped hierarchical network is greater than the maximum allowable number of time synchronization layers, a control node is selected according to the maximum allowable number of time synchronization layers, wherein the control node is the child node One or more of; after the time synchronization is completed with the root node through the control node, the time synchronization between the control node and the child node can be performed, which can solve the problem that the error of all nodes cannot be controlled within a certain range in the related art The time synchronization is carried out through the control node to meet the synchronization accuracy requirements within the error control range.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a time synchronization processing method and device. Background technique [0002] For multi-node time synchronization, two aspects must be considered in the design of time synchronization algorithm, one is to reduce the energy consumption caused by time synchronization itself; the other is to provide high time synchronization accuracy to effectively reduce the energy consumption caused by other key technologies. energy consumption. [0003] The related technology adopts a hierarchical mode, establishes a network through hierarchical discovery, and selects nodes, algorithms, or interactive methods such as two-way and broadcasting for time synchronization based on factors such as accuracy and energy consumption. After the establishment of the hierarchy, the hierarchical relationship is relatively solid, and the adjustment measures after the absence of intermediate no...
