Dynamic Synchronization Interval Adjustment for Time Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time synchronization techniques between communication devices suffer from decreased accuracy over time due to frequent transmission and reception of synchronous packets, which is inefficient and degrades synchronization accuracy.
Innovation Solution
A synchronizing system and method that adjust the synchronization interval based on the absence of abnormality notifications, reducing the communication frequency of synchronous packets while maintaining synchronization accuracy by increasing the interval when no abnormalities are detected and shortening it upon detection.

1Productivity
If the interval at which synchronous packets are transmitted and received is made long, then the communication frequency is reduced, but the synchronization accuracy degrades
Solution Approach 1:
The synchronization interval is made dynamic rather than fixed. The second synchronizing device adjusts the interval based on abnormality notifications received from the first device. When abnormalities are detected, the interval is shortened to maintain accuracy; when no abnormalities occur, the interval is extended to improve communication efficiency. This dynamic adjustment resolves the contradiction by adapting the interval to actual system conditions.
Solution Approach 2:
The system implements a feedback mechanism where the first synchronizing device notifies the second device of abnormalities in real-time. The second device uses this feedback information to adjust the synchronization interval accordingly. This feedback loop enables the system to maintain high synchronization accuracy while reducing unnecessary communications, resolving the trade-off between accuracy and communication efficiency.
2Measurement precision
If synchronous packets are transmitted frequently, then synchronization accuracy is maintained, but communication resource consumption increases
Solution Approach 1:
The transmission frequency of synchronous packets is dynamically adjusted based on system state. The second synchronizing device changes the synchronization interval according to abnormality notifications, reducing transmission frequency when the system is stable and increasing it when abnormalities are detected. This dynamic approach minimizes communication resource consumption while maintaining accuracy when needed.
Solution Approach 2:
The system changes the time interval parameter of synchronous packet transmissions based on abnormality conditions. By adjusting this parameter dynamically, the system can reduce the number of transmissions (and thus resource consumption) when synchronization is stable, while increasing transmissions when accuracy is compromised by abnormalities.

AI summary
Provided is a synchronization system comprising a first synchronization device and a second synchronization device which carry out synchronization processing by transmitting and receiving synchronization packets in accordance with a synchronization protocol and which synchronize the times thereof. The first synchronization device, which corresponds to a slave device, notifies an abnormality to the second synchronization device when an abnormality related to time synchronization processing is detected. The second synchronization device, which corresponds to a master device, increases the interval during which synchronization is performed as the length of time during which an abnormality notification is not received increases.
