摘要
基于桥梁健康实时监测系统的总体框架和现状,重点分析了该系统中存在的时钟不同步的问题。介绍了几种主要的时钟同步技术和方法。根据监测系统的实际情况、结合常用的时钟同步技术,设计提出了一种适用于小范围局域网内的高速实时数据采集系统的时钟同步模型,阐述了该模型的时钟同步过程。最后,讨论了该模型的时钟同步过程的误差来源及其系统的扩展性问题。
The general structure of a bridge health monitoring system of is introduced The clock asynchronization in the system is analyzed. Some of the clock synchronization techniques and methods are introduced. In analyzing the instance of the monitoring system and combining with clock synchronization techniques, a clock synchronization model which adapts to a high speed and real - time data gather system in a small range LAN is presented. A clock synchronization process of the model is expounded. Finally the error source of the model and the expansibility of the system are discussed.
