| description | Nowadays, the performance requirements of time unified system in various fields are getting higher and higher. In the past, most time unified system used NTP for time synchronization, but the protocol can only provide millisecond-level synchronization accuracy, and the master clock is generally fixed, which cannot meet the requirements of high precision and high robustness in application fields such as measurement and control. Based on this, this paper conducts an in-depth study on the application of high-reliability time unified system based on PTP timing. The system adopts the PTP protocol for timing, which can make the system time synchronization precision reach nanosecond level, and based on the BMC algorithm，the system is designed and implemented the double mode of manual setting and automatic selection for the dual-system hot standby function, which satisfies the high-performance requirements of the time unified system in the application fields such as measurement and control. Compared with the previous time unified system, the system greatly improves the timing accuracy and robustness of time unified system. |
