Improvement of the Precise Time Synchronization Algorithm Based on IEEE1588

In the field of industrial control,clock synchronization precision is an important factor that affects the real-time performance of the industrial Ethernet.In order to satisfy the request for precise clock synchronization in the industrial Ethernet,this paper conducts the research to the IEEE1588 high-precision time synchronization protocol,carries on the elaboration to the principle of high-precision synchronization,proposes the corresponding improvement algorithm for asymmetric communication paths.Finally,the algorithm is tested in a self-designed system.The results of test show that the improved algorithm can effectively increase the clock synchronization accuracy under asymmetric communication paths.
