摘要
时间同步是网络化测试技术的重要课题之一。根据网络化混合测试系统的体系结构的特点,分析了常用时间同步方法。提出分层式混合同步的方法实现了系统的时钟同步。这种同步方式将GPS硬件方式和改进的IEEE1588软件方式有机地融合在一起,很好地结合了系统的层次结构,具有良好的扩展性和兼容性。
Time synchronization is one of the important issues of network test technology. According to the characteristic of the network mixed-test system architecture, the commonly used method of time synchronization is analyzed, and a method of layered hybrid synchronization is proposed to realize the system clock synchronization. The hard technology-GPS and improved soft technology- IEEE1588 are syncretized well in this method which suits the structure very well and has expansibility and compatibility.
