Title:
SYNCHRONIZED DATA NETWORK SYSTEM, AND METHOD FOR INITIALIZING AND SYNCHRONIZING SAME
Document Type and Number:
WIPO Patent Application WO/2024/017947
Kind Code:
A3
Abstract:
The invention relates to a synchronized data network system (10), comprising a data network (100) that connects data network nodes (110) to one another via direct bidirectional data transmission links (x) between neighbouring data network nodes (110) in order to exchange data; and an arbitrary node chain of the data network nodes (110) consisting of successive first (110A), second (110B) and third (110C) data network nodes, wherein the second data network node (110B) is designed to receive data transmitted on a first direct data transmission link (xAB) between the first (110A) and the second (110B) data network node from the first data network node (110A) on a data forwarding link (xABBC) and to forward said data in transmit mode to the third data network node (110C) on a second direct data transmission link (xBC) between the second (110B) and the third (110C) data network node. The synchronized data network system (10) is characterized in that the second data network node (110B) is designed to delay forwarding of the data on a single-hop data forwarding link (xABB, xBBC) between the first and the third data network node (110A, 110C) such that the hop latency (dH_ABB, dH_BBC) is equal to a predetermined fixed common hop latency (dCH). This thus enables a simple method for achieving implicit time synchronization of the data network system.
