摘要
时标系统对加速器控制系统中的所有控制计算机的时钟起同步作用,以使加速器的各种数据有共同的时间戳。这样加速器各种数据可确定精确的因果关系,便于数据分析、故障诊断等。本文基于对两个大型加速器时标系统的硬件架构及实现机制的分析,设计了一套实验室环境下的时标系统,就测试结果与国外加速器的时标系统进行比较和总结,为上海同步辐射装置的时标系统研制提供有利参考。
The main function of timestamp system is to synchronize the clock of control computers in the control system of an accelerator. Through timestamp system, one can make sure the precise causality between all kinds of data for trouble shooting and data analysis. In this paper, we describe the principle of timestamp system, and analyze the hardware structure and realization mechanism between several large accelerators in detail. A design of timestamp systems for lab environment is presented for applications at SSRF. Finally, we summarize the difference between these timestamp systems.
