ABSTRACT: Currently, the high-speed
serial fiber-optic ring net communication is a main method for performing the distributed
control network topology and control mode. Because of a network transmission
delay inherent in the topology, synchronization between nodes has become a
critical issue which needs to be studied. The existing synchronization methods
largely depend on the complex communication protocol. Therefore, this paper has
proposed a method of automatic measurement and compensation of synchronization
delay, and analyzed its operating principle and implementation procedure in
detail. The results obtained from the experiments prove the proposed method to
be correct, effective and practicable.
