摘要:
[摘　要]工业以太网中,各设备对时钟同步精度的要求越来越高.以IEEE１５８８协议理论为基础,设计一种基于无迹卡尔曼滤波的时钟同步算法.通过对 PTP得到的时间差进行观测,获取对下一个周期时钟偏差、时钟频率的估计值,使用该估计值校正从时钟频率和时钟偏差,以保证时钟同步.实验证明,该方法能够有效提高时钟同步精度。
Abstract:
In industrial Ethernet, devices have higher and higher requirements for clock synchronization accuracy. Based on the theory of IEEE1588 protocol, a clock synchronization algorithm based on unscented Kalman filter is designed. By observing the time difference obtained by PTP, the algorithm obtains the estimated value of clock deviation and clock frequency of the next cycle, and uses the estimated value to correct the slave clock frequency and clock deviation to ensure clock synchronization. Finally, experiments show that this method can effectively improve the accuracy of clock synchronization.
