Abstract—In distributed measurement and control system, it is the key to need a global time to determine the order of events happened in system, to achieve the effectiveness of monitoring and control data which is various information transmissions or operation state , therefore the clock synchronization technology is required to synchronize the every slave subsystem. IEEE 1588 precision clock synchronization protocol can effectively solve the time synchronization problem in distributed measurement and control system. First, the basic principles of the IEEE 1588 precision clock synchronization protocol and related program flow are introduced in this article. Second, two algorithms applied to clock synchronization including DS comparison algorithm and State decision algorithm was further proposed and discussed. Meanwhile, the clock synchronization with PTP (Precision Time Protocol) between two devices communication was implemented on the platform of embedded Linux operating system. Finally test showed the accuracy of synchronization was reached less than dozens of microseconds.

Index Terms—IEEE1588 ; PTP; clock synchronization ; Linux.
