摘要

超前时钟同步是无线分布式系统(WDS)的一项重要基本要求。IEEE 1588标准定义了测量和控制系统中高精度的时钟同步协议。本文提出了一种基于IEEE 1588标准的WDS时间同步方案。分析了IEEE 1588在无线分布式系统中的应用，重点讨论了拓扑选择和分域对PTP同步精度的影响。该方案采用了两种典型的无线网络拓扑结构，即单层星形结构和多层树形结构。通过Matlab仿真，对两种网络拓扑同步方案的同步精度进行了评价。此外，通过仿真研究了不同接入机制下PTP时钟同步精度。

Clock Synchronization of Wireless Distributed System Based on IEEE 1588

Advanced clock synchronization is a basic requirement of significant importance for the wireless distributed system (WDS). IEEE 1588 standard defines a high precision clock synchronization protocol in measurement and control systems. In this paper, an excellent time synchronization scheme for WDS based on the IEEE 1588 standard is proposed. The application of IEEE 1588 on wireless distributed system is analyzed with emphasis on PTP synchronization accuracy influenced by topology choice and domain division. The two typical wireless network topologies, i.e. single-level star structure and multi-level tree structure, are employed in the scheme. Matlab simulations are carried out to evaluate the synchronization accuracy of the synchronization scheme for both network topologies. In addition, the PTP clock synchronization accuracy is researched on different access mechanism through simulations.
