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 highprecision 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.关键词
