摘要
在高速公路联网收费系统中,由于各种收费业务管理的需求,保持系统内各计算机之间的时间同步非常重要。在研究收费系统网络内部时间同步体系结构的基础上,本文介绍了几种比较实用的计算机时间同步方法,对每种方法的适用条件和优缺点进行了分析,并根据高速公路收费系统工程实际应用的需要推荐两种简便可靠的方法,对于其他有时间同步要求的计算机网络和系统应用也同样具有参考价值。
Time synchronization is very important in expressway toll system to satisfy all kinds of management requirements of tolling business. On the basis of study of the hierarchical architecture of time synchronization in the computer network of expressway toll system, characteristics and applicable conditions of several useful methods of time synchronization are analyzed in this paper. Two simple and reliable methods are recommended according to actual needs in expressway toll system, which also could be referenced in other computer networking systems that require time synchronization.
