Abstract

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.
