摘要
为实现分布式系统高精度同步数据采集及实时控制,提出一种基于IEEE 1588协议的分布式系统时钟同步方法。通过分析影响同步精度的因素,采用FPGA设计时间戳生成器,并且采用晶振频率补偿时钟解决时间戳的精确获取和从时钟相对主时钟的频率纠偏等问题。
In order to realize high accuracy synchronous data acquisition and control in distributed system,a distributed system clock synchronization method based on IEEE1588 protocol is proposed.Through analyzing the factors which affects the synchronized precision,using field programmable gate array （FPGA） designs timestamp generator oscillator frequency compensation solves the problems of timestamp precision acquisition and error correction from relative master time frequency.
