摘要：
In modern distributed measure and control systems, transmission and processing of real-time data requires each communication node to work in a unified time base in order to ensure the timeliness of data transmission. IEEE1588 precision clock synchronization protocol (PTP) is aimed to solve the high-precision clock synchronization, which supports software or hardware implementation. This paper analyzes the factors that affect the accuracy of clock synchronization. Considering the special requirements of the protocol implemented in embedded systems, we propose an adaptive exponential smoothing algorithm to achieve high-precision clock synchronization. Experiments show that this algorithm can significantly improve the accuracy of clock synchronization.
