基于IEEE 1588协议的时间触发以太网同步算法
Time-triggered Ethernet Synchronization Algorithm Based on IEEE 1588 Protocol
摘要
Abstract
Time-triggered Ethernet (TTE) based on time synchronization of IEEE 1588 solves the uncertainty problem of data transmission delay without considering the effect of timestamp accuracy on the synchronization accuracy of the IEEE 1588 protocol.To solve this problem, a frequency drift estimation and bias estimation model is established to calculate the impact of time stamp accuracy on the synchronization accuracy of the IEEE 1588 protocol, and the error of time synchronization between TTE protocol and the IEEE 1588 protocol is deduced theoretically.Experimental results show that the TTE network based on IEEE 1588 protocol has higher time synchronization accuracy than the standard TTE time synchronization algorithm when the timestamp accuracy reaches 0.1 μs or higher.关键词
