Problems solved by technology

[0005] However, using the general absolute difference adjustment method will cause the time counter to be compared with the central node in time, and the offset will be large and small, resulting in a large time jitter
Therefore, the time jitter of the communication network will be relatively large with this simple real-time absolute error adjustment method, which is not conducive to effectively improving the stable operation of the communication network

Abstract

The invention provides a time synchronization method for weight flexible decremental adjustment, relates to the technical field of network communication, and solves the technical problem of poor network operation stability caused by adjusting network synchronization time difference by absolute difference at present. Including different-layer adjustment coefficients, same-layer adjustment coefficients, comparison errors and actual errors, introduction of construction rules for said layer adjustment coefficients and same-layer adjustment coefficients, and actual error and said different-layer adjustment coefficients, same-layer adjustment coefficients, and comparison errors the mathematical relationship between them. The invention fully takes into account fast time synchronization and smooth and stable synchronous operation, effectively improves the stable synchronization performance of each node in the network, and ensures the stable and synchronous operation of the entire network.

Description

technical field [0001] The invention relates to the technical field of network communication, and in particular, to a time synchronization method for weight flexible decreasing adjustment. Background technique [0002] In the MESH communication system, it is often composed of a central node and several sub-nodes, and two transmission media of wireless and carrier are used. According to the transmission relationship to the central node, the child nodes are distributed in several levels around the central node. [0003] in this typical MESH communication system. The central node sends periodic central beacons, the first-tier sub-nodes realize time synchronization according to the received central beacons and forward the beacons in a timely manner, and other layers of nodes realize time synchronization according to the received central beacons or forwarded beacons. Continue to forward beacons until the outermost layer of the network achieves time synchronization. In a long s...
