CONTINUOUS TIME SYNCHRONIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240028066 titled 'CONTINUOUS TIME SYNCHRONIZATION

Simplified Explanation

The abstract describes a method and network for time synchronization between a master and slave in an interrupt-capable network component. The method involves determining a time offset between the master and slave time, adjusting the first time fraction of the offset using a time jump in the first synchronization step, and adjusting the second time fraction of the offset in successive synchronization steps using frequency alignment and/or a time jump. The second time fraction can be a non-integer multiple within a specific range of the interrupt cycle duration. The actual occurring cycle duration of the interrupt deviates from the predefined cycle duration by no more than a predefined deviation in each of the second synchronization steps.

Original Abstract Submitted

a method and network for time synchronization of at least one master and at least one slave, which is an interrupt-capable network component. a time offset between a master time and a slave time is determined. a first time fraction of the determined time offset is adjusted in first synchronization step(s) using a time jump. the first time fraction corresponds to an integer multiple of the cycle duration of the interrupt(s) and a second time fraction of the determined time offset is adjusted in a number of successive second synchronization steps using frequency alignment and/or a time jump. the second time fraction corresponds to a non-integer multiple from the range ]−1.0[ and ]0.1[ of cycle duration of the interrupt(s). in each of the number of second synchronization steps, an actual occurring cycle duration of the interrupt(s) deviates from the predefined cycle duration by no more than a predefined deviation.
