摘要:在分布式测控系统中,各分布式设备、独立的智能传感器、作动器与系统之间的时钟同步是系统测控数据有效性的关键。IEEE 1588精密时钟同步协议有效地解决了分布式测控系统时间同步问题,也是新测试系统总线标准LXI的核心技术之一。首先介绍了IEEE 1588时钟同步的基本原理,之后主要针对最新发布的IEEE 1588 2.0版本所采用的新技术、新方法进行了分析,为进一步研究打下基础。 |

Abstract:In distributed measurement and control system,the clock synchronization between the system and the distributed device, independent smart sensors,actuators is the key to the effectiveness of monitoring and control data.IEEE 1588 precision clock synchronization protocol can effectively solve the time synchronization problem in distributed measurement and control system,and it is also one of the core technologies of the new test system standard bus LXI.First of all,the basic principles of the IEEE 1588 clock synchronization are introduced.Later,the use of new technologies and methods of the latest released version 2.0 of IEEE 1588 are mainly analyzed,and the analysis lays a foundation for further study. |
